program is also known as the GSA Schedules Program or the Multiple Award Schedule (MAS) Program. The FSS program is directed and
managed by GSA and provides Federal agencies with a simplified process for obtaining commercial supplies and services at prices
associated with volume buying. Indefinite-delivery, indefinite quantity contracts are awarded to provide supplies and services
at stated prices for given periods of time. GSA has delegated authority to the VA to manage the Schedules for medical supplies
under the VA FSS program. This solicitation is issued to establish contracts which may be used on a nonmandatory basis by eligible
users, as a source of supply for the supplies or services described herein, for domestic and/or overseas delivery. At a minimum,
contract holders are required to deliver their products within the 48 contiguous states, Alaska, Hawaii, Puerto Rico, Washington,
DC, and U.S. territories. Domestic delivery also includes a port or consolidation point, within the aforementioned areas, for orders
received from overseas activities. Offerors who cannot provide the required geographic coverage will not be considered for award.
This solicitation further requires that offered prices cover delivery to destinations (i.e. F.O.B. destination) located within
the 48 contiguous states and the District of Columbia. Offerors can choose whether or not prices cover delivery f.o.b. destination
to Alaska, Hawaii, and the Commonwealth of Puerto Rico. Additionally, the solicitation defines the number of calendar days after
receipt of order (ARO) within which delivery must be made. Special Item Numbers (SINs): FSS solicitations set forth broad categories
of accepted products/services, referred to as Special Item Numbers (SINs), listed in the Continuation of SF1449 in Vendor Response
Continuation Page 4 of 7

 

     

     

    

 

 

65IIA Mass Modification 0008 Document 02. Offerors are not required
to submit their entire catalog of products/services but are free to choose which items they will offer as long as those items fall
within one of the solicitation’s pre-defined SIN categories. Items that do not fall within one of these SINs are considered
to be out of scope of the solicitation and cannot be awarded. An item’s acceptability under the schedule may be further restricted
by clause 52.225-5 Trade Agreements, limitations on certain types of commercial items, and a determination of fair and reasonable
pricing. Please be advised of the below restrictions applicable to this schedule for specific SINs/types of products. • Glucose
Monitoring Products: Glucose monitoring equipment, such as blood glucose monitoring (BGM) units and continuous glucose monitoring
(CGM) units, no longer fall within the scope of this schedule. All types of glucose monitoring products, including accessories
and consumables, fall under Schedule 65 VII, Invitro Diagnostics, Reagents, Test Kits, and Test Sets, new SIN 555-11. Please note
that these products do not fall under GSA schedules. Low Vision Aids: Although this schedule does not currently have a SIN category
which provides coverage for low vision aids, these items may be proposed under SIN A-94 Introduction of New Products/Services pending
the addition of a new Low Vision Aids SIN category with specifically defined parameters. We will currently accept low vision aids
under SIN A-94 on a case by case basis, at the discretion of the agency, provided that the item is a medical product/device. Please
note that this does not include prescription eyewear and reading glasses, nor does it include products covered under GSA’s
FSS programs, such as loupes/magnifiers and IT related low vision equipment (which falls under GSA schedule 70, SIN 132 8, subcategory
 “Equipment for • Physically Challenged”). Personal Medical Alert Devices: No types of personal medical alert/monitoring
devices fall within the scope of this schedule. These fall under GSA schedule 70, SIN 132-8. • • Air Purifiers: Air purifiers
and other such air filtration/disinfection equipment do not fall within the scope of this schedule. These fall under GSA Schedule
56, SIN 563 27. • Pool Lifts: Pool lifts do not fall under SIN A-76 Patient Lifts nor SIN A-77 Patient Transfer Apparatus.
These fall under GSA Schedule 51V, SIN 105 002 and GSA Schedule 78, SIN 192 19. • Home Diagnostic Testing: Home diagnostic
tests do not fall within the scope of this schedule. Tests, test kits, and test sets fall under schedule 65 VII, Invitro Diagnostics,
Reagents, Test Kits, and Test Sets. Be advised that currently there is no provision for home diagnostic testing/monitoring services
under any VA schedule. Medical IT: This schedule only permits medical IT products/systems where the purpose of the product/system
is for medical treatment/diagnosis. No line items will be awarded under this schedule for which the product is of a general IT
nature, such as a keyboard, monitor, tablet, etc. These types of general IT items would only be permissible under this schedule
when provided as an integral part of a medical IT system being offered. Additionally, laptops/tablets pre-loaded with medical therapy
software should only be capable of operating the installed software (i.e. not be a general use laptop/tablet with pre-loaded medical
therapy software). All non-permissible IT items fall under GSA schedule 70. • • Lease/Rental: This schedule does not
permit leased items. Rental items may be proposed provided that the following conditions are met: 1) The offeror rents such items
commercially in the normal course of business; 2) The proposed rental term of any task order does not exceed 12 months; and 3)
The offeror must negotiate in good faith a rental agreement at the task order level with such agreement adhering to the parameters
set forth in the “General Terms and Conditions Applicable to Rental” section of Solicitation Document 01. When proposing
rental Continuation Page 5 of 7

 

     

     

    

 

 

65IIA Mass Modification 0008 items, the offeror must clearly
identify the item as a rental in the Name/Product Description column of the price proposal spreadsheet (Document 03) and must state
the period for the rental (e.g. “daily rental”, “monthly rental”, etc.). New Items vs. Refurbished or “Grey
Market Goods” Note: This section does not apply to rental items. This solicitation is for the award of new items only. The
Contractor shall provide only new equipment and new parts for the required products described herein. Absolutely no “grey
market goods” or refurbished products shall be provided under any delivery order. Grey market goods are defined as genuine
branded goods sold outside of an authorized sales-territory (or by non-authorized dealers in an authorized territory) at prices
lower than being charged in authorized sales territories (or by authorized dealers). All equipment must be covered by the manufacturer’s
warranty. Trade Agreements Act The Trade Agreements Act is applicable to all Schedules. In exercising its authority under FAR Part
25, Foreign Acquisition, purchases by Ordering Activities are restricted to either U.S.-made or designated country end products.
A U.S.-made product can be either 1) an article that is mined, produced, or manufactured in the United States, or 2) an article
that is substantially transformed in the United States into a new and different article of commerce with a name, character, or
use distinct from that of the article or articles from which it was transformed. It is the offeror’s responsibility to verify
that all offered products are U.S. made or designated country end products as defined in clause FAR 52.225-5. When an item consists
of components from various countries and the components are assembled in a designated country, the test to determine country of
origin is substantial transformation (see FAR 25.001(c)(2)). Offerors requiring a determination on substantial transformation can
go to the US Customs and Border Protection (CBP) Office of Regulations and Rulings. For the purposes of services, origin is determined
by the country in which the firm providing the service is established, not the location at which the services are performed. Commercial
Items - Limitations Per GSA regulations at 538.271(a), MAS awards are for commercial items as defined in FAR 2.101. Certain types
of “custom” items fall under this definition as modified commercial items. For example, FSS accepts configurable items,
such as configurable wheelchairs, and custom count items, such as pharmaceutical tablets packaged in quantities specifically for
the Government. FSS, however, has made a business decision not to award contracts for the following: • • Custom Packs
Non-Configurable Custom Products Made to Individual Specifications, including, but not limited to, such items as custom orthotics,
custom dental products, and prescription eyeglasses. Additionally, per the commercial item definition at FAR 2.101, FSS cannot
award contracts to installation, maintenance, and repair service companies who do not also provide similar services to the general
public (i.e. Government only service providers). FDA Regulatory Requirements Offerors of products classified as medical devices
by the U.S. Food and Drug Administration shall be in compliance with the Federal Food Drug and Cosmetic (FD&C) Act, as amended,
and regulations promulgated there under (codified in 21 CFR Parts 800-1299). Offerors of medical devices not in compliance with
these regulations shall not be considered for award under this solicitation. Notice of Additional Requirements - Ordering Level
In addition to the terms and conditions set forth in this solicitation, the contractor may, in the performance of orders issued
under this contract, be responsible for further requirements at the Continuation Page 6 of 7

on these potential, additional requirements, please see the note in Solicitation Document 01 after FAR clause 52.216-18 Ordering.
Please note that the VA does not promote the use of any company’s specific Schedule contract. Vendors should be aware that
obtaining a VA Schedule contract is not a guarantee of sales. Vendors awarded a VA Schedule contract will need to market their
supplies and services to Government customers as they would to commercial customers. A listing of eligible schedule users can be
found at on GSA’s website at http://gsa.federalschedules.com/resources/eligible-gsa-schedule-users/. ELECTRONIC ACCEPTANCE
