MSSC, INC v AIRBOSS FLEXIBLE PRODUCTS CO
 
Docket No. 163523.  Argued December 7, 2022 (Calendar No. 2).  Decided July 11, 2023. 
 
 
MSSC, Inc., brought an action in the Oakland Circuit Court against Airboss Flexible 
Products Co., alleging anticipatory breach of contract and seeking to enforce a purchase order 
between the parties after Airboss threatened to stop filling orders unless MSSC agreed to a price 
increase.  Airboss supplied products to MSSC, and MSSC used those products to manufacture 
parts for their customers.  The parties’ purchase order for the Airboss products was identified as a 
“blanket” order that listed the parts to be supplied but did not include specific quantities.  Instead, 
the purchase order indicated that quantities would be based on the needs of an MSSC customer.  
MSSC was obligated to create and send “releases” per the terms and conditions, but neither the 
purchase order nor the terms and conditions obligated MSSC to send any number of firm orders 
to Airboss—either as a raw number or as a percentage of MSSC’s total need.   
 
 
MSSC brought the instant suit, and the trial court granted a preliminary injunction in favor 
of MSSC, finding that the contract was a requirements contract and was likely enforceable.  
Airboss moved for summary disposition, arguing that the purchase order failed to satisfy MCL 
440.2201(1), the statute of frauds of the Uniform Commercial Code, MCL 440.1101 et seq.  In 
response, MSSC moved for summary disposition, arguing that the blanket purchase order was a 
requirements contract that satisfied the statute of frauds.  The trial court, James M. Alexander, J., 
granted MSSC’s motion for summary disposition, concluding that because the purchase order was 
identified as a “blanket” order, it contained a “quantity term” that satisfied the statute of frauds.  
Airboss appealed, and the Court of Appeals, GADOLA, P.J., and JANSEN and O’BRIEN, JJ., affirmed.  
338 Mich App 187 (2021).  Airboss sought leave to appeal in the Supreme Court, and the Supreme 
Court granted the application.  508 Mich 1024 (2022). 
 
 
In an opinion by Justice WELCH, joined by Chief Justice CLEMENT and Justices BERNSTEIN 
and CAVANAGH, the Supreme Court held: 
 
 
The term “blanket” order, without more, does not express a quantity term that satisfies 
MCL 440.2201(1), the statute of frauds of the Uniform Commercial Code, MCL 440.1101 et seq.  
The Court overruled Great Northern Packaging, Inc v Gen Tire & Rubber Co, 154 Mich App 777 
(1986), to the extent that it held to the contrary.

1.  MCL 440.2201(1) provides that contracts entered into for the sale of goods worth $1,000 
or more must be in writing and that a court may only enforce the contract up to the quantity of 
goods set forth in writing.  When a contract fails to include a quantity term, parol evidence—
evidence outside the contract itself—cannot be offered to supply a missing quantity term.  A 
requirements contract is a contract in which a buyer promises to buy, and a seller to supply, a set 
amount or percentage of the goods or services that a buyer needs during a specified period, such 
as “all requirements of the buyer.”  Requirements contracts may be created by a “blanket” purchase 
order, which, along with the amount or percentage to be purchased and supplied, sets forth the 
terms governing items such as price, length of contract, warranty, details, indemnification, and 
termination.  However, a quantity term is what is needed to specifically create a requirements 
contract.  MCL 440.2306 provides, in pertinent part, that a term that measures the quantity by the 
requirements of the buyer means such actual requirements as may occur in good faith, except that 
no quantity unreasonably disproportionate to any stated estimate may be tendered or demanded.  
In contrast, release-by-release contracts are governed by a blanket purchase order that sets the 
overall contract terms, and the buyer issues subsequent releases that set forth the specific quantity 
the buyer needs; however, unlike a requirements contract, the blanket purchase order does not set 
forth the share of the buyer’s need to be purchased from the supplier.  Although the seller is not 
bound to accept future orders in the same manner as with a requirements contract, the seller is 
bound by the terms in the purchase order when future releases are issued and accepted.  The key 
difference between a requirements contract and a release-by-release contract is the level of mutual 
obligation between the parties and the risk each party bears.  A requirements contract assures the 
seller that the buyer will be a customer for the length of the contract, but the seller cannot reject 
future orders for the length of the contract.  In contrast, a release-by-release contract gives both 
parties the freedom to allow their contractual obligations to expire in short order by either not 
issuing or not accepting a new release.   
 
 
2.  In this case, the documents between the parties created a release-by-release contract, 
not a requirements contract.  The documents did not contain a quantity term; rather, the purchase 
order only stated that MSSC would issue releases.  While the releases contained a firm quantity 
and MSSC’s estimated future need, those releases only constituted an obligation binding Airboss 
as to each individual release if Airboss accepted—not a promise to fulfill all future releases.  The 
trial court in this case erroneously relied on Cadillac Rubber & Plastics, Inc v Tubular Metal Sys, 
LLC, 331 Mich App 416 (2020), to hold that the use of a blanket purchase order combined with a 
substantial history of prior dealings between the parties created a requirements contract that bound 
Airboss.  The trial court’s reliance on Cadillac Rubber was erroneous because in Cadillac Rubber, 
the Court of Appeals had found that a quantity term existed—“a quantity between one part and 
100%”—which therefore allowed it to use parol evidence to discern the parties’ intent.  In this 
case, however, there was no quantity term; accordingly, parol evidence could not be used to 
determine the existence of a quantity term.  The parties instead entered into a release-by-release 
contract.  The purchase order and incorporated terms and conditions in this case created a blanket 
agreement, while the releases created individual purchasing contracts governed by the umbrella 
terms.  This saved the parties from renegotiating complex terms for each order while allowing the 
parties greater flexibility than a requirements contract would allow.  Either party was able to walk 
away from the agreement once a release was fulfilled, and Airboss’s choice to do so was not legally 
actionable. 
 
 
3.  The contractual requirement of “good faith and fair dealing” did not create a 
requirements contract.  Every contract has an implied duty of good faith and fair dealing.  But the 
quantity term must be explicit under MCL 440.2201(1), and an implied duty is very different from 
an explicit written requirement.  Good faith alone cannot solve the problem of the missing quantity 
term. 
 
 
4.  A 2015 communication between the parties that stated that Airboss was “awarded 
the . . . value add of MSSC for the life of the . . . program in exchange for continuous improvement 
and year over year productivity” did not create a requirements contract.  In context, “value add” 
was more appropriately read as a statement of pricing—and Airboss sharing in profitability of the 
parts it makes—not actual sourcing.  An award of the “value add” in exchange for “continuous 
improvement and year over year productivity” showed an expectation of decreasing costs-per-unit 
leading to greater reward to Airboss.  This communication was more appropriately read as a per-
unit dollar figure shared with Airboss, not an obligation for MSSC to purchase parts from Airboss. 
 
 
Reversed and remanded to the Court of Appeals for further proceedings. 
 
 
Justice VIVIANO, joined by Justice ZAHRA, concurring in part and dissenting in part, agreed 
with the majority that the term “blanket” order, without more, did not express a quantity term and 
that Great Northern should be overruled to the extent that it held to the contrary.  Justice VIVIANO 
also agreed that neither the provision in the purchase order stating that MSSC “shall issue” releases 
to Airboss nor the UCC’s imposition of “an obligation of good faith” created a requirements 
contract such that the statute of frauds was satisfied.  However, the lower courts did not address 
the May 2015 update to the purchase order, and it was unclear to Justice VIVIANO whether this 
provision obligated MSSC to purchase a quantity of parts from Airboss such that the statute of 
frauds was satisfied.  Accordingly, rather than hold that the parties did not enter into a requirements 
contract, Justice VIVIANO would have remanded this case to the trial court for it to resolve this 
issue. 
 
 
Justice BOLDEN did not participate in the disposition of this case because the Court 
considered it before she assumed office.

WELCH, J.  
This case involves a dispute between automotive suppliers.  MSSC, Inc., sued 
Airboss Flexible Products Co. because Airboss refused to continue providing parts at a 
price set forth in a blanket purchase order.  The resolution of this dispute depends on the 
type of contract the parties created.  The trial court granted MSSC’s motion for summary 
disposition, finding that the parties created a requirements contract, thus binding Airboss

to continue selling parts to MSSC.  The Court of Appeals affirmed, and Airboss appealed 
the result to this Court.  Contrary to the lower courts, we find that the parties entered into 
a release-by-release contract, which allowed Airboss to stop selling parts to MSSC.  We 
therefore reverse and remand for further proceedings that are consistent with this opinion.   
I.  BACKGROUND 
A.  THE UCC’S STATUTE OF FRAUDS  
To understand the facts in this case, it is first helpful to provide some legal 
background regarding supplier contracts.  Under Michigan law, contracts for the sale of 
goods—including supplier contracts—are governed by the Uniform Commercial Code (the 
UCC), MCL 440.1101 et seq.  The UCC contains a statute-of-frauds provision that governs 
which agreements must be in writing.  MCL 440.2201(1).  That section provides: 
Except as otherwise provided in this section, a contract for the sale of 
goods for the price of $1,000.00 or more is not enforceable by way of action 
or defense unless there is a writing sufficient to indicate that a contract for 
sale has been made between the parties and signed by the party against whom 
enforcement is sought or by his or her authorized agent or broker.  A writing 
is not insufficient because it omits or incorrectly states a term agreed upon 
but the contract is not enforceable under this subsection beyond the quantity 
of goods shown in the writing.  [Id. (emphasis added).] 
The first sentence of MCL 440.2201(1) mandates that contracts entered into for the sale of 
goods worth $1,000 or more must be in writing.  The second sentence of MCL 440.2201(1) 
allows for some terms to be missing or incorrect but provides that a court can only enforce 
the contract up to the quantity set forth in writing.  In other words, quantity is the only 
essential term required by the statute of frauds.  See In re Frost Estate, 130 Mich App 556, 
559; 344 NW2d 331 (1983).  If an agreement for the sale of goods contains a quantity, then 
 
3 
 
the agreement satisfies the statute of frauds.  See Lorenz Supply Co v American Standard, 
Inc, 419 Mich 610, 614; 358 NW2d 845 (1984).   
Thus, in reviewing an agreement involving the sale of goods for more than $1,000, 
a court must endeavor to identify the “quantity term” in the contract to determine whether 
the contract is enforceable.  When a contract fails to include a quantity term, parol 
evidence—that is, evidence outside the contract itself—“[cannot] be offered to supply a 
missing quantity term.”  In re Frost Estate, 130 Mich App at 559.  In contrast, when a 
contract provides a quantity term but fails to express details sufficient to determine the 
specific or total quantity, “it may be explained or supplemented by parol evidence.”  Id. at 
560, citing MCL 440.2202 (the UCC’s parol evidence provision).   
B.  TYPES OF QUANTITY TERMS IN SUPPLIER CONTRACTS 
The UCC allows for a contract’s quantity to be measured “by the output of the seller 
or the requirements of the buyer . . . .”  MCL 440.2306(1).1  This provision allows for 
parties to enter into contracts that provide a quantity term but lack specificity as to the total 
of goods agreed upon.  Two types of contracts fall under this provision: output contracts 
and requirements contracts.  Both are commonly used between suppliers.  Today we 
formally recognize a third type of contract: a release-by-release contract.  
 
An “output contract” defines quantity by the supply provided by the seller.  See 
Black’s Law Dictionary (11th ed), p 408 (defining “output contract” as “[a] contract in 
 
1 “A term which measures the quantity by the output of the seller or the requirements of 
the buyer means such actual output or requirements as may occur in good faith, except that 
no quantity unreasonably disproportionate to any stated estimate or in the absence of a 
stated estimate to any normal or otherwise comparable prior output or requirements may 
be tendered or demanded.”  MCL 440.2306(1).

which a seller promises to supply and a buyer to buy all the goods or services that a seller 
produces during a specified period and at a set price”).  In contrast, a “requirements 
contract” is a contract that defines quantity by reference to the buyer’s requirements.  See 
id. at 410 (defining “requirements contract” as “[a] contract in which a buyer promises to 
buy, and a seller to supply, all the goods or services that a buyer needs during a specified 
period”); see also Acemco, Inc v Olympic Steel Lafayette, Inc, unpublished per curiam 
opinion of the Court of Appeals, issued October 27, 2005 (Docket No. 256638), p 9 
(defining a typical requirements contract as “an agreement ‘in which the seller promises to 
supply all the specific goods or services which the buyer may need during a certain period 
at an agreed price in exchange for the promise of the buyer to obtain his required goods or 
services . . . from the seller’ ”) (citation omitted).   
In agreements between a buyer and supplier-seller, requirements contracts are often 
created by an umbrella agreement, which is also referred to as a “blanket purchase order.”  
This umbrella agreement sets forth the terms governing items such as price, length of the 
contract, warranty details, indemnification, and termination.  See David Engineering Co, 
LLC v Morbern Inc, unpublished opinion of the United States District Court for the Eastern 
District of Michigan, issued July 31, 2012 (Case No. 11-12615), pp 2-3 (describing a Tier-
1 supplier’s supply agreement which “set[] forth the terms and conditions for all purchase 
orders of a particular part or program during the life of the [agreement]” and against which 
the buyer issued four purchase orders); see also 77A CJS (February 2023 update), Sales, 
§ 41 (“A blanket purchase order does not oblige the seller to manufacture or ship; that 
obligation arises when the buyer issues a shipment, production, or release order against the 
blanket purchase order.”).  Most importantly, in a requirements contract, the terms of the 
 
5 
 
blanket purchase order also dictate that the buyer will obtain a set share of its total need 
from the seller (such as “all requirements of the buyer”).  This phrase satisfies the quantity 
term required by the statute of frauds.  MCL 440.2306(1).  To supplement this general 
term, the buyer will typically later issue “releases” to let the seller know its specific short-
term requirements.  
Finally, similar to requirements contracts, some agreements are governed by a 
blanket purchase order that sets the overall contract terms, and the buyer issues subsequent 
releases that set forth the specific quantity the buyer needs.  But unlike a requirements 
contract, the blanket purchase order does not set forth the share of the buyer’s need to be 
purchased from the supplier.  See Advanced Plastics Corp v White Consol Indus, Inc, 
unpublished opinion of the United States Court of Appeals for the Sixth Circuit, issued 
January 18, 1995 (Case No. 93-2155), p 2; 47 F3d 1167 (Table) (finding that the parties’ 
“Blanket Purchase Order Terms and Conditions” did not create a requirements contract 
because there was no quantity term and “the parties intended for [the buyer] to purchase 
quantities of parts only according to its releases, and not according to its requirements”).  
Instead, the purchase order is more appropriately thought of as an umbrella agreement that 
governs the terms of future contract offers.  See David Engineering Co, unpub op at 2.  
Although the seller is not bound to accept future orders in the same manner as with a 
requirements contract, the seller is bound by the terms agreed to in the purchase order when 
future releases are issued and accepted.  See Opdyke Investment Co v Norris Grain Co, 413 
Mich 354, 359; 320 NW2d 836 (1982) (“A contract to make a subsequent contract is not 
per se unenforceable; in fact, it may be just as valid as any other contract.”).  These 
agreements are also known as “release-by-release” contracts.  See Killips, Section 2-201

Isn’t Optional: Option Provisions, Requirements Contracts, and Cadillac Rubber, 41 Mich 
Bus L J 46, 47 (2021) (describing release-by-release contracts as structured so that their 
overarching terms are “only enforceable once a firm quantity is stated,” which “happens 
only when a release is issued” and accepted).2 
The key difference between a requirements contract and a release-by-release 
contract rests in the level of mutual obligation between the parties and the risk each party 
bears.  A requirements contract assures the seller that the buyer will be a customer for the 
length of the contract, but the seller cannot reject future orders for the length of the contract.  
In contrast, a release-by-release contract “gives both parties the freedom to allow their 
contractual obligations to expire in short order by either not issuing or not accepting a new 
release.”  Section 2-201 Isn’t Optional, 41 Mich Bus L J at 47; see also Advanced Plastics 
Corp, unpub op at 2-3 (finding that the blanket terms of the contract at issue, which stated 
that the only firm obligations were in issued and accepted releases, “convincingly 
demonstrate[] that the parties did not enter into a requirements contract”).  The seller cannot 
 
2 While Michigan caselaw has not previously identified a release-by-release contract as a 
specific contract type, we adopt the term “release-by-release” to describe a contract with 
an umbrella agreement that includes general terms but which lacks a quantity term and 
which operates via releases issued by the buyer to the seller.  See Brief for Aisin World 
Corp of America, Inc., et al. as Amici Curiae (August 4, 2022) (Docket No. 163523) at 11.  
Although this term might be “new,” the concept is not.  We have found multiple cases 
describing these contracts by reference to what they are not—requirements contracts—
without naming what they are called.  See Advanced Plastics Corp, unpub op at 2-3 
(describing a release-by-release contract and stating that the terms of the contract at issue 
in that case demonstrated that the parties “did not enter into a requirements contract”); 
David Engineering Co, LLC, unpub op at 2 (describing an agreement by which one contract 
“sets forth the terms and conditions for all purchase orders . . . [but] is not itself, a purchase 
order”).

be guaranteed future business from the buyer, but the seller can accept or reject any offer 
for future orders.   
C.  FACTS AND PROCEEDINGS OF THIS CASE 
The parties in this case are both automotive suppliers and have contracted with one 
another since at least 2013.  Plaintiff, MSSC, Inc., is a Tier-1 automotive supplier and 
contracts to build assemblies for automobile companies.  Tier-1 suppliers take parts 
provided by Tier-2 suppliers and make assemblies or systems for automobile companies.  
Defendant, Airboss Flexible Products Co., is a Tier-2 automotive supplier that obtains raw 
materials from Tier-3 suppliers, makes parts, and supplies the parts to Tier-1 suppliers. 
Sometime before July 2013, MSSC contracted with Fiat Chrysler Automobiles 
(now Stellantis) to build suspension systems for various vehicles.  At the outset of their 
relationship, MSSC supplied Airboss with a purchase order.  That purchase order included 
specific terms and incorporated the general terms and conditions found on MSSC’s website 
by reference.  It also included the following language: 
If this Purchase Order is identified as a “blanket” order, this order is valid 
and binding on seller for the lifetime of the program or until terminated 
pursuant to MSSC’s Terms and Conditions. 
The purchase order further stated that “[a]nnual volume is an estimate based on the 
forecasts of MSSC’s customers and cannot be guaranteed.”  The incorporated terms and 
conditions stated, in relevant part: 
2. BLANKET ORDERS: If this order is identified as a “blanket 
order”, [MSSC] shall issue a “Vendor Release and Shipping Schedule” to 
[Airboss] for specific part revisions, quantities and delivery dates for 
Products.  [MSSC] shall have the right to cancel, adjust or reschedule the 
quantities of Products shown in such “Vendor Release and Shipping 
Schedule,” except that it may not cancel, adjust or reschedule the Products 
 
8 
 
shown as “Firm Obligations” on such “Vendor Release and Shipping 
Schedule.” 
In the normal course of operations, MSSC created a “Vendor Release and Shipping 
Schedule” pursuant to the terms and conditions and sent it to Airboss.  This document 
included a “firm order”—or an order that could not be changed—as well as longer-term 
estimates.  MSSC was thus obligated to create and send “releases” per the terms and 
conditions, but neither the purchase order nor the terms and conditions obligated MSSC to 
send any number of firm orders to Airboss—either as a raw number or as a percentage of 
MSSC’s total need.   
Airboss produced the parts for MSSC, and the parties’ relationship developed 
through the releases under the conditions set forth by the purchase order and terms.  The 
requirements, prices, and other terms set out in the blanket purchase order were 
occasionally modified in a manner that appears to have been mutually beneficial for both 
parties for roughly six years.  Sometime in 2016, for instance, the parties edited the 
language in the purchase order to include language stating that Airboss “is awarded 
the . . . value add of MSSC for the life of the . . . program in exchange for continuous 
improvement and year over year productivity.”  In mid-2019, however, Airboss began to 
experience losses on 6 of the 42 parts it produced for MSSC.  Eventually, according to 
Airboss, these annualized losses totaled over $1 million.  As a result, Airboss sought to 
pass the price increases onto MSSC.  MSSC agreed to a price increase on the condition 
that Airboss enter into a letter agreement barring further unilateral price increases for the 
lifetime of the program.  Although Airboss agreed, Airboss later alleged that it continued 
 
9 
 
to lose money and sent a letter to MSSC in December 2019, stating that it would cease 
taking further orders from MSSC starting in March 2020.   
MSSC, in response, sued Airboss for anticipatory breach of contract and sought 
specific performance on the contract as written.  The Oakland Circuit Court granted a 
preliminary injunction in favor of MSSC, finding that the contract was a requirements 
contract and was likely enforceable.  Subsequently, Airboss moved for summary 
disposition, arguing that the purchase order failed to satisfy the statute of frauds and that it 
showed no mutuality of obligation because it did not require MSSC to purchase any 
quantity of parts from Airboss but instead obligated Airboss to supply any quantity MSSC 
requested.3  MSSC also moved for summary disposition, arguing that Airboss was bound 
to provide parts for the life of the program.  The trial court granted MSSC’s motion for 
summary disposition.  In its order and opinion, the trial court found that the purchase order 
contained a “quantity term,” as required by the statute of frauds, because the purchase order 
was identified as a “blanket” purchase order.  In other words, the trial court interpreted the 
term “blanket” to be a quantity term.  Further, the trial court examined the past dealings 
between the parties and found that their interactions indicated an intent to enter into a 
requirements contract.  Finally, the trial court rejected Airboss’s argument that the 
agreement failed for lack of mutuality of obligation, specifically noting that requirements 
contracts do not fail on that basis alone given that a buyer must operate in good faith and 
abide by commercial standards of fair dealing.   
 
3 Airboss moved for summary disposition under MCR 2.116(C)(7) (“[D]ismissal of the 
action . . . is appropriate because of . . . [the] statute of frauds . . . .”) and MCR 
2.116(C)(10) (“[T]here is no genuine issue as to any material fact, and the moving party is 
entitled to judgment or partial judgment as a matter of law.”).   
 
10 
 
The Court of Appeals affirmed in a published per curiam decision.  It held that “the 
use of ‘blanket order’ in this case was intended as an imprecise quantity term,” MSSC, Inc 
v Airboss Flexible Prod Co, 338 Mich App 187, 195; 979 NW2d 718 (2021), and that the 
use of that term was sufficient to create a requirements contract that satisfied the statute of 
frauds.  The Court of Appeals went on to hold that the purchase order “did not state a 
specific quantity because plaintiff’s need for parts was dependent on its customer’s 
production schedule, which is common in the automotive industry.”  Id.  It also affirmed 
the trial court’s holding that the contract did not fail for lack of mutuality of obligation.  Id. 
at 196.  Airboss sought leave to appeal in the Supreme Court.  We granted the application 
and asked the parties to address “whether the purchase order between the parties, together 
with the relevant written terms and conditions, satisfied the requirements of the Uniform 
Commercial Code’s statute of frauds, MCL 440.2201(1).”  MSSC, Inc v Airboss Flexible 
Prod Co, 508 Mich 1024, 1024 (2022).  As set forth below, we find that they did not. 
II.  STANDARD OF REVIEW 
This Court reviews grants of summary disposition de novo.  See DeRuiter v Byron 
Twp, 505 Mich 130, 139; 949 NW2d 91 (2020).  This case also involves questions of 
statutory and contractual interpretation, which we likewise review de novo.  See id.; 
Schmalfeldt v North Pointe Ins Co, 469 Mich 422, 426; 670 NW2d 651 (2003).  When we 
review an issue de novo, we “review this issue independently, with no required deference 
to the courts below.”  In re Ferranti, 504 Mich 1, 14; 934 NW2d 610 (2019).

III.  ANALYSIS 
We find that the documents between the parties created a release-by-release 
contract, not a requirements contract.  Significantly, the writings between MSSC and 
Airboss did not contain a quantity term.  Rather, the purchase order in this case only stated 
that MSSC would issue releases; it made no reference anywhere to a quantity term.  While 
the releases contained a firm quantity and MSSC’s estimated future need, those releases 
only constituted an obligation binding Airboss as to each individual release if Airboss 
accepted—not a promise to fulfill all future releases.  In other words, because the purchase 
order contained no quantity term, as is required to be an enforceable contract for the sale 
of goods under the UCC, Airboss was free to provide MSSC with notice that it would no 
longer accept future releases.  We therefore reverse the Court of Appeals decision and, as 
discussed more fully later in this opinion, overturn Great Northern Packaging, Inc v Gen 
Tire & Rubber Co, 154 Mich App 777; 399 NW2d 408 (1986), to the extent that it 
contradicts this opinion.  
A.  OUTPUT AND REQUIREMENTS CONTRACT CASELAW 
There are only a few Michigan cases that have discussed output and requirements 
contracts that are relevant to this case.  In In re Frost Estate, 130 Mich App at 558, the 
Court of Appeals analyzed an output contract that provided for the sale of “ ‘all wood 
sawable.’ ”  The total quantity of wood at issue was ambiguous because the contract failed 
to identify which parcel of land the agreement covered.  Id. at 561.  However, the quantity 
term—“all”—was specific.  The Court of Appeals held that the term “all” “referred to a 
quantity and was sufficient to meet the requirements” of the statute of frauds and that parol 
 
12 
 
evidence was admissible to determine the relevant parcel or parcels the agreement covered.  
Id. at 565.   
The same concept applies to requirements contracts.  See MCL 440.2306(1) 
(defining output and requirements contracts); see also Lorenz Supply Co, 419 Mich at 616 
(providing that “the quantity term . . . alone must be specified in writing” in a requirements 
contract).  A requirements contract can be nonspecific as to the quantity, but it must still 
have a quantity term that can be evaluated further using parol evidence. 
This Court evaluated an alleged requirements contract in Lorenz Supply Co, 419 
Mich 610.  In that case, Lorenz Supply Company and American Standard, Inc., entered 
into an oral distributorship agreement whereby American Standard agreed to provide 
Lorenz with $420,000 in “out of the wall” plumbing materials (e.g., wash basins and 
faucets).  Id. at 613 n 1; id. at 618 (BRICKLEY, J., concurring).  The only writing that 
referred to the existence of a distributorship agreement was a letter welcoming Lorenz to 
“ ‘the family of American Standard distributors . . . .’ ”  Id. at 623 (BRICKLEY, J., 
concurring).  After a breakdown between the parties, Lorenz sued American Standard for 
breach of the oral distributorship agreement.  American Standard argued that the 
distributorship was actually a sale-of-goods contract governed by the UCC and therefore 
was unenforceable for lack of a written quantity term.  We held that the distributorship 
agreement did not constitute a sale of goods and, thus, the UCC did not apply.  As a result, 
the oral agreement was enforceable.  Id. at 615 (opinion of the Court).  Of significance to 
this case, we noted in Lorenz that the quantity term in a UCC contract may not be inferred 
but “must, . . . under § 2-201, be specifically stated.”  Id. at 614-615.  
 
13 
 
Just two years after Lorenz was decided, the notion of what constitutes “quantity” 
under the UCC’s statute of frauds became muddled.  In Great Northern Packaging, 154 
Mich App at 779, the seller, Great Northern Packaging, Inc., sold a packaging system to 
General Tire and Rubber Company, which, in turn, used the system to ship products to 
Ford Motor Company.  General Tire issued a “change order” (equivalent to the purchase 
orders at issue here) that modified the quantity heading from 50 units to a “blanket order” 
with no expiration date.  Id. at 780.  After a Great Northern employee started working for 
a competitor, General Tire began ordering from both companies; eventually, General Tire 
ordered more units from the competing company.  Great Northern sued to enforce the 
agreement, claiming that the term “blanket order” required General Tire to purchase all its 
packaging systems from Great Northern.  In response, General Tire argued that the contract 
was void under the statute of frauds because “blanket” was not a quantity term.  Id. at 786.  
The Court of Appeals found for Great Northern, holding that “the term ‘blanket order’ 
expresses a quantity term, albeit an imprecise one,” analogous to the “ ‘all wood sawable’ ” 
quantity term in In re Frost Estate.  Great Northern Packaging, 154 Mich App at 787, 
quoting In re Frost Estate, 130 Mich App at 558, 560.  But the Court of Appeals failed to 
recognize that although the total quantity might be imprecise in a requirements contract (as 
in In re Frost Estate), the quantity term must be provided in the writing and cannot be 
provided via parol evidence.   
For example, a produce market owner could agree with Orchard X that “as a blanket 
policy, I will buy all my apples from Orchard X for $3.00/bushel.”  While we don’t know 
the specific number or total quantity of bushels that the market owner will purchase, we 
know that 100% of the apples the market owner purchases will come from Orchard X.  
 
14 
 
How do we know this?  Because the market owner stated that they would purchase “all my 
apples” from Orchard X.  Accordingly, “all my apples” constitutes the required quantity 
term in this example.  The fact that there is a “blanket policy” is not the provision that 
informs the quantity term.  
Alternatively, if the market owner says to Orchard X that “as a blanket policy, I will 
only purchase apples for $3.00/bushel,” we are left to question both what percentage of 
apples sold at the market will come from Orchard X and how many bushels of apples the 
market will purchase.  There is a difference between a quantity term (“all my apples”) and 
a precise quantity (a specific number of bushels).  They are not synonymous.  A contract 
may leave the final or total quantity ambiguous or unspecified in a requirements contract, 
but it may not state an imprecise quantity term.  As a result, to the extent that Great 
Northern stands for the conclusion that the term “blanket order” alone infers a quantity 
term in an alleged UCC sale-of-goods contract, it is overruled.   
Finally, the trial court in this case relied heavily upon Cadillac Rubber & Plastics, 
Inc v Tubular Metal Sys, LLC, 331 Mich App 416; 952 NW2d 576 (2020), when it ruled 
in favor of MSSC.  That case also involved a Tier-1 automotive supplier (Tubular Metal 
Systems, LLC) and a Tier-2 supplier (Cadillac Rubber & Plastics, Inc., doing business as 
Avon Automotive).  Tubular Metal issued two purchase orders that incorporated general 
terms and conditions and provided that “MATERIAL REQUIREMENT WILL BE 
RELEASED WEEKLY.”  Additionally, Tubular Metal’s terms and conditions “provided 
for the issuance of material authorization releases under which [Tubular Metal] was 
obligated to purchase from [Cadillac Rubber] a quantity between one part and 100% of 
[Tubular Metal’s] requirements.”  Id. at 429-430.  Cadillac Rubber argued that all 
 
15 
 
requirements contracts must be exclusive—i.e., that Tubular Metal could only use Cadillac 
Rubber as its supplier.  The Court of Appeals disagreed and determined that the agreement 
was a nonexclusive requirements contract.  Id. at 430 & n 6.  The Court of Appeals also 
found that the parties had, for eight years, behaved in a manner that suggested an intent to 
create a requirements contract and that there was no evidence that Tubular Metal failed to 
act in good faith.  Id. at 430-431.   
B.  DOCUMENTS DID NOT CREATE A REQUIREMENTS CONTRACT 
As an initial matter, we agree with the Court of Appeals in Cadillac Rubber that 
requirements contracts do not always have to be exclusive.  A seller can agree to provide a 
nonexclusive part of the buyer’s total need.  But the trial court in this matter relied on 
Cadillac Rubber to find that the use of a blanket purchase order combined with a substantial 
history of prior dealings between the parties created a requirements contract that bound 
Airboss.  This was erroneous because in Cadillac Rubber, the Court found the existence of 
a quantity term—“a quantity between one part and 100%”—which therefore allowed it to 
use evidence of past practice (or parol evidence) to discern the parties’ intent.4  Id. at 430-431.   
 
4 Airboss has urged us to overrule the holding in Cadillac Rubber that the purchase order’s 
language providing for “a quantity between one part and 100%” constituted a proper 
quantity term for a nonexclusive contract under MCL 440.2201(1), thus allowing for the 
use of parol evidence to determine the parties’ intent as to the existence of a requirements 
contract.  Airboss urges us instead to adopt the position taken in Acemco, unpub op at 5, 
which held that a requirements contract cannot grant “complete discretion” to the buyer 
because “ ‘[a]ny’ quantity is in fact no quantity at all.”  We decline to address this apparent 
inconsistency today because, in this case, there was no quantity term set forth in the 
purchase order or in any other document.  Whether Cadillac Rubber and Acemco can be 
reconciled and, if not, which is correct remain questions for another day. 
 
16 
 
Here, the documents between MSSC and Airboss do not contain such a quantity 
term.  The terms of the agreement, as stated in the purchase order and the terms and 
conditions, set blanket policies governing the sale of parts between MSSC and Airboss.  
These terms did not create any obligation for MSSC to purchase any parts from Airboss.  
The purchase order and terms and conditions leave both the quantity term and total quantity 
undefined, which violates the UCC’s statute of frauds.  While the terms state that MSSC 
“shall issue” releases, there is no obligation for those releases to represent a share of 
MSSC’s total needs.  MSSC could issue release after release stating “zero” in the firm-
obligations category while contracting with another Tier-2 supplier for 100% of its 
production without running afoul of the purchase order or the terms and conditions.  This, 
by definition, is not a requirements contract.  The lower courts found that the purchase 
order’s “blanket order” language and the statement that “[a]nnual volume is an estimate 
based on the forecasts of MSSC’s customers and cannot be guaranteed” evidenced a 
quantity term.  But those provisions do not, in fact, state a quantity term.  Rather, they are 
silent.  
Whether exclusive or not, a quantity term must be stated in a UCC sale-of-goods 
contract.  And although parol evidence can be used to determine the specific total of an 
imprecise quantity in a requirements or output contract under the UCC, it cannot be used 
to determine the existence of the quantity term itself.  See In re Frost Estate, 130 Mich 
App at 558-559.  By creating a quantity term when there was none—just as the Court in 
Great Northern did—and then relying upon past practice between the parties, the lower 
courts here committed reversible error. 
 
17 
 
MSSC next argues that the contractual requirement of “good faith and fair dealing” 
creates a requirements contract even if the quantity term is missing.  According to MSSC, 
this is because “the party who will determine the quantity . . . is obligated to operate in 
good faith and according to commercial standards of fair dealing to ensure that the 
requirements ordered will approximate a reasonably foreseeable figure.”  Plaintiff’s Brief 
on Appeal (May 2, 2022) at 32, quoting Cadillac Rubber, 331 Mich App at 426, in turn 
quoting MCL 440.2306, comment 2 (quotation marks omitted).  Thus, because Airboss 
does not argue that MSSC acted outside the bounds of good faith or fair dealing, MSSC 
claims that Airboss is bound to supply 100% of MSSC’s requirements at the negotiated 
price.  We find this unpersuasive.  Every contract has an implied duty of good faith and 
fair dealing.  But the quantity term must be explicit under MCL 440.2201(1), and an 
implied duty is very different from an explicit written requirement.  Holding to the contrary 
would mean that every contract without an explicit quantity term meets the requirements 
of the statute of frauds because all contracts require good faith and fair dealing.  If this 
were a requirements contract, the duty of good faith and fair dealing would require both 
MSSC and Airboss to act in good faith while fulfilling their respective obligations.  
However, good faith alone cannot solve the problem of the missing quantity term.  The 
terms of this agreement allow MSSC to simply contract with another Tier-2 supplier to 
provide the parts at a cheaper rate5 without acting in bad faith or engaging in unfair dealing.  
This would not violate the parties’ implied duties because the purchase order does not 
 
5 MSSC, in briefing and during oral argument, discussed the difficulty of finding another 
Tier-2 supplier that had been approved by Stellantis.  Although that is a practical concern 
that this Court does not ignore, it does not change the reality of what a contract permits or 
does not permit.  
 
18 
 
require that any business be directed to Airboss.  In short, the “good faith and fair dealing” 
requirement applies to all contracts—it does not create a requirements contract.   
Finally, MSSC points to a 2015 communication between the parties that stated that 
Airboss “is awarded the . . . value add of MSSC for the life of the . . . program in exchange 
for continuous improvement and year over year productivity.”  MSSC claims that this 
language created a requirements contract.6  Again, we find this argument unpersuasive.  In 
context, “value add” is more appropriately read as a statement of pricing—and Airboss 
sharing in profitability of the parts it makes—not actual sourcing.  An award of the “value 
add” in exchange for “continuous improvement and year over year productivity” shows an 
expectation of decreasing costs-per-unit leading to greater reward to the manufacturer 
(Airboss).  It is more appropriately read as a per-unit dollar figure shared with Airboss, not 
an obligation for MSSC to purchase parts from Airboss.7 
 
6 There is a dispute between the parties as to whether the parts discussed in this addendum 
are the same parts at issue in this case.  Given our holding today that the parties did not 
enter into a requirements contract, we need not decide this matter.   
7 While the partial concurrence would remand this case to the trial court to determine 
whether the e-mail communications constituted an agreement, we find that to be 
unnecessary.  Airboss’s initial motion for summary disposition included a motion under 
MCR 2.116(C)(10), which tests the factual sufficiency of a claim.  The partial concurrence 
is correct that the lower courts failed to address this issue despite full discovery and full 
briefing on the matter.  Whether a contract exists is a question of law that—had the lower 
courts decided it—we would review de novo.  Bandit Indus, Inc v Hobbs Int’l, Inc (After 
Remand), 463 Mich 504, 511; 620 NW2d 531 (2001).  This Court has the full record before 
it, including the relevant e-mails, following extensive discovery.  As a result, we disagree 
with our partially concurring colleague that we are not in a position to review the disputed 
e-mails and assess their impact upon the existence—or nonexistence—of a legal contract.  
 
19 
 
In summary, none of the documents between MSSC and Airboss created any 
obligation for MSSC to purchase from Airboss.  Without such obligation, there is no 
requirements contract.  It is a release-by-release agreement. 
C.  THE PARTIES ENTERED INTO A RELEASE-BY-RELEASE CONTRACT 
Given our holding that the documents in this case lacked a quantity term and did not 
create a requirements contract under the UCC, we hold that the parties entered into a 
release-by-release agreement.  The purchase order and incorporated terms and conditions 
created a blanket—or umbrella—agreement, while the releases created individual 
purchasing contracts governed by the umbrella terms.  This saved the parties from 
renegotiating complex terms for each order while allowing the parties greater flexibility 
than a requirements contract would allow.  Either party was able to walk away from the 
agreement once a release was fulfilled, and Airboss’s choice to do so is not legally 
actionable.  Parties are free to balance the competing forces of flexibility and certainty.  
MSSC and Airboss chose greater flexibility at the expense of certainty. 
IV.  CONCLUSION 
In conclusion, the purchase order, terms and conditions, and other writings between 
MSSC and Airboss lacked a quantity term.  No document reflected a number or portion of 
parts that MSSC committed to purchase from Airboss on an ongoing basis.  The term 
“blanket” is not a quantity term, and we overrule Great Northern Packaging, 154 Mich 
App 777, to the extent that it conflicts with that holding.  Given the lack of a quantity term, 
the agreement between MSSC and Airboss did not comply with the UCC’s statute-of-
frauds provision set forth in MCL 440.2201(1), and it was error for the lower courts to use 
 
20 
 
parol evidence to determine the intent of the parties.  Without a quantity term, the parties 
could not have entered into a requirements contract under MCL 440.2306(1).  Instead, we 
hold that the parties entered into a release-by-release contract.  We reverse the Court of 
Appeals opinion and remand this case to the Court of Appeals for further proceedings that 
are consistent with this opinion.

v 
No. 163523 
 
AIRBOSS FLEXIBLE PRODUCTS CO., 
 
 
 
Defendant/Counterplaintiff-
Appellant. 
 
 
 
VIVIANO, J. (concurring in part and dissenting in part). 
At issue is whether an enforceable contract exists between plaintiff, MSSC, Inc., 
and defendant, Airboss Flexible Products Co.  The answer to this question turns on whether 
the agreement between the parties contains a quantity term such that it satisfies MCL 
440.2201(1), the statute of frauds of the Uniform Commercial Code, MCL 440.1101 et seq.  
I agree with the majority that the term “blanket” order, without more, does not express a 
quantity term and that Great Northern Packaging, Inc v Gen Tire & Rubber Co, 154 Mich 
App 777; 399 NW2d 408 (1986), should be overruled to the extent that it held to the 
contrary.  I also agree that several of MSSC’s theories for why a valid requirements contract 
exists are without merit.  However, portions of the majority’s opinion are unnecessarily 
broad and lack supporting authority.  Rather than hold that the parties did not enter into a 
valid requirements contract, I would remand this case to the trial court for it to resolve this 
issue.

I.  THE TERM “BLANKET” ORDER IS NOT A QUANTITY TERM 
I agree with the majority’s conclusion that the term “blanket” order is not a quantity 
term sufficient to satisfy the UCC’s statute of frauds provision in MCL 440.2201(1).  
MSSC argues that the term “blanket” order is a quantity term that is consistent with a 
requirements contract.  To create a requirements contract, the agreement must include “[a] 
term which measures the quantity by . . . the requirements of the buyer . . . .”  MCL 
440.2306(1); see also Methodist Health Servs Corp v OSF Healthcare Sys, 859 F3d 408, 
410 (CA 7, 2017) (explaining that a requirements contract “obligate[s] [the] buyer to 
purchase all, or a substantial portion of, its requirements of specific goods or services from 
one supplier”); 2A Anderson, UCC (3d ed, December 2022 update), § 2-306:28 (“A 
requirements contract obligates the buyer to purchase all the goods that the buyer will need 
for a particular use contemplated by the parties.”).  The trial court in this case held that, 
like in Great Northern, the term “blanket” order in the parties’ contract expresses a quantity 
term, and the Court of Appeals agreed.  See Great Northern, 154 Mich App at 787 (holding 
that “blanket order” is a quantity term, “albeit an imprecise one,” and that parol evidence 
can be used to clarify what quantity was intended). 
But the term “blanket” order, on its own, cannot be a quantity term because it is 
silent as to any quantity of parts that MSSC was required to purchase from Airboss.  See 
Royal Paper Box Co v E R Apt Shoe Co, 290 Mass 207, 209-210; 195 NE 96 (1935) 
(determining that the “dominant words” in the contract at issue were “Requirements for 
Balance of year to Jan 1 1930,” not the estimates that followed, and that “[t]he words 
‘Blanket Order’ in the column headed ‘Quantity’ lend further support to this construction”).  
As the majority recognizes, if a contract states an imprecise quantity, parol evidence is 
 
3 
 
admissible to “explain[] or supplement[]” the agreement, but parol evidence may not be 
admitted to add a quantity term to a contract in which no quantity term exists.  In re Frost 
Estate, 130 Mich App 556, 559-560; 344 NW2d 331 (1983).  Thus, I agree with the 
majority that the lower courts in this case made the same mistake that the Court of Appeals 
made in Great Northern by reading “blanket” order as creating a quantity term where none 
existed.1 
II.  WHETHER THE PARTIES NONETHELESS ENTERED INTO A VALID 
REQUIREMENTS CONTRACT 
That “blanket” order, on its own, is not a quantity term does not end the inquiry.  
Whether a quantity term was stated elsewhere in the agreement hinges on whether the 
parties entered into a requirements contract.  A requirements contract existed here if MSSC 
was obligated to purchase parts from Airboss.2 
 
1 This does not mean that a blanket order is necessarily inconsistent with a requirements 
contract.  A purchase order between two parties with a valid requirements contract may be 
a “blanket” order, but there would need to be some other provision in the contract indicating 
that the buyer is required to purchase all or a portion of its requirements from the seller to 
satisfy the quantity term.  See Methodist Health Servs, 859 F3d at 410; MCL 440.2306(1). 
2 I agree with the majority that a requirements contract can exist even when there is not 
100% exclusivity for the buyer’s needs as long as there is a meeting of the minds that the 
buyer is required to purchase some portion of its needs from the seller.  See Cadillac 
Rubber & Plastics, Inc v Tubular Metal Sys, LLC, 331 Mich App 416, 426-427; 952 NW2d 
576 (2020); id. at 433-434 (SHAPIRO, J., concurring in part and dissenting in part); see also 
2A Anderson, UCC (3d ed, December 2022 update), § 2-306:31 (“A requirements contract 
does not necessitate that the buyer purchase ‘all’ of the buyer’s requirements of the goods 
from the seller.”).  I take no position as to whether the majority in Cadillac Rubber was 
correct to hold that “between one part and 100% of Tubular’s requirements” was a proper 
quantity term for a requirements contract.  Cadillac Rubber, 331 Mich App at 430 (opinion 
of the Court). 
 
4 
 
Relying on Cadillac Rubber & Plastics, Inc v Tubular Metal Sys, LLC, 331 Mich 
App 416; 952 NW2d 576 (2020), the trial court in this case looked at the use of a “blanket” 
purchase order and the conduct of the parties to conclude that a valid requirements contract 
existed.  But the trial court’s reliance on Cadillac Rubber was misplaced because the Court 
of Appeals in Cadillac Rubber had first analyzed the language of the contract and 
concluded that a valid requirements contract existed before looking to parol evidence.  
Cadillac Rubber, 331 Mich App at 430-431.  The trial court here erred by using parol 
evidence—the “course of conduct” of the parties—to create a quantity term where none 
existed.  See In re Frost Estate, 130 Mich App at 559-560.3 
In addition to the “blanket” order language in the purchase order, MSSC raises three 
other arguments in an attempt to demonstrate that the parties had a valid requirements 
contract.  First, MSSC points to the provision in the purchase order stating that MSSC 
“shall issue” releases as evidence that it was obligated to purchase its required parts from 
Airboss.  I agree with the majority that this provision does not establish a requirements 
contract because it did not obligate MSSC to issue releases representing all or even a share 
of its needs.  See Methodist Health Servs, 859 F3d at 410; 2A Anderson, UCC (3d ed, 
December 2022 update), § 2-306:31. 
 
3 Under the UCC, courts may consider the parties’ “course of performance” when 
interpreting the language of a contract.  MCL 440.1303(4) (“A course of performance or 
course of dealing between the parties or usage of trade in the vocation or trade in which 
they are engaged or of which they are or should be aware is relevant in ascertaining the 
meaning of the parties’ agreement [and] may give particular meaning to specific terms of 
the agreement . . . .”).  “[T]he express terms of an agreement and any applicable course of 
performance, course of dealing, or usage of trade must be construed whenever reasonable 
as consistent with each other.”  MCL 440.1303(5).  However, parol evidence alone cannot 
establish a quantity term under the statute of frauds. 
 
5 
 
Second, MSSC argues that “the covenant of good faith and fair dealing” obligated 
MSSC to buy parts from Airboss such that it created a requirements contract.  I agree with 
the majority that MSSC’s argument is unpersuasive.  At issue here is a contract subject to 
the UCC, and every contract under the UCC “imposes an obligation of good faith in its 
performance and enforcement.”  MCL 440.1304.  A quantity term must be “shown in the 
writing,” MCL 440.2201(1), but this “good faith” obligation is found in the statute, not the 
purchase order.  Therefore, MSSC’s argument fails. 
Finally, MSSC points to the following update to the purchase order in May 2015 as 
evidence of a valid requirements contract: 
The following 2016 WK/WD part numbers will be added to the 
blanket as line items when the parts are PPAPed approved.  AirBoss Flexible 
Products is awarded the bushing/bonding/assembly value add of MSSC for 
the life of the 2016/2017 generation of the WK74 and WD75 program in 
exchange for continuous improvement and year over year productivity.  
(Program life could go into 2018-2019 for this generation) 
Although MSSC relied on this provision in the lower courts, the lower courts did not 
address it in their decisions.  It is unclear to me whether this provision obligated MSSC to 
purchase a quantity of parts from Airboss such that the statute of frauds is satisfied.  The 
majority cursorily states that this provision deals with pricing and reflects an expectation 
of decreasing costs per unit.  But the majority does not explain how it reached this 
conclusion, and how it did so is unclear to me.  Additionally, as the majority acknowledges, 
the parties dispute whether the parts discussed in this update are the same parts as those at 
issue in this case.  For these reasons, rather than attempting to answer a question that neither 
lower court addressed, I would remand this case to the trial court for it to determine whether 
 
6 
 
this provision obligated MSSC to purchase a quantity of parts from Airboss such that the 
statute of frauds is satisfied.4 
III.  CONCLUSION 
In conclusion, I believe that a question remains as to whether the agreement between 
the parties contains a valid quantity term.  I agree with the majority that the term “blanket” 
order, without more, is not a quantity term, that Great Northern should be overruled to the 
extent it held to the contrary, and that the lower courts erred by using parol evidence to 
create a quantity term as opposed to merely resolving an ambiguity as to the quantity term.  
I also agree that neither the provision in the purchase order stating that MSSC “shall issue” 
releases to Airboss nor the UCC’s imposition of “an obligation of good faith” created a 
requirements contract such that the statute of frauds is satisfied.  But I believe that there 
remains a legitimate question as to whether the May 2015 update to the purchase order 
obligated MSSC to purchase a quantity of its requirements from Airboss.  I would remand 
this case to the trial court for it to address that issue.

4 On remand, the trial court would also have the opportunity to determine whether any 
other provisions of the purchase orders support Airboss’s argument that a requirements 
contract was formed, including a provision in one of the purchase orders stating that the 
order was a “binding” agreement that lasted “for the lifetime of the program . . . .”
