Bond Requirements for Nonroad 

Spark-Ignition Engines 

On October 8, 2008, the Environmental Protection Agency (EPA) 

published regulations adopting new exhaust emissions standards 

for nonroad spark-ignition engines, also known as Small SI engines 

(73 FR 59034). As part of these regulations, EPA has adopted a 

bond requirement for manufacturers that are subject to these new 

regulations. 

Why is EPA requiring a bond for Small SI engine manufacturers? 

Before a manufacturer can introduce an engine into commerce in the United States, 

they must first apply for a Certificate of Conformity (certificate) from EPA. The certification process requires manufacturers to demonstrate that engines and equipment 

meet applicable emission standards. Once a manufacturer has received a certificate, 

several important obligations apply to the certifying manufacturer or importer. For 

example, we require ongoing testing of production engines, as well as reporting of 

recurring defects. Manufacturers may need to pay penalties if there is a violation and 

may need to perform a recall if their products are noncompliant. 

For manufacturers operating within the United States, we are generally able to communicate clearly and insist on compliance. Depending on the circumstances, we may 

meet with specific manufacturer representatives, halt production, or seize assets. For 

manufacturers without staff or assets in the United States, these alternatives are not 

available. Our limited ability to enforce requirements or to recover appropriate penalties increases the risk of environmental problems as well as problems for consumers. 

This creates the potential for a manufacturer to gain a competitive advantage if they 

do not have substantial assets or operations in the United States. We have learned 

from several recent enforcement cases that there is an increasing number of manufacturers selling certified engines in the United States without committing the necessary 

resources to meet their in-use and long-term obligations. 

Warranty is an example of a potential compliance obligation that manufacturers 

commit to when they receive a certificate from EPA. Regulations require that

engine manufacturers must service warranty claims for emission-related defects that occur during the prescribed warranty period. We have experience with manufacturers that did not have 

the resources to make warranty repairs if necessary. Such manufacturers benefit from being able 

to legally sell their product in the United States without bearing the full range of associated 

obligations. 

To address this concern, we adopted a requirement for manufacturers of certified engines to meet 

bond requirements to cover the cost of any potential compliance or enforcement actions under 

the Clean Air Act. 

When does the bond requirement take effect? 

This requirement was adopted in regulations that were published on October 8, 2008, at 40 

CFR 1054.690 (73 FR 59034). Starting with the 2010 model year, applications for certification 

must include information related to the bond, including a commitment to secure a bond if that 

is required for the manufacturer. Starting January 1, 2010, all Small SI engines that are subject 

to the bond requirement must have the bond in place before introducing 2010 and later model 

year engines into U.S. commerce. U.S. Customs and Border Protection in particular will be 

looking for documentation related to required bonds starting in 2010. 

Does the bond requirement apply to all manufacturers? 

The bond provisions apply to all manufacturers that certify and sell Small SI engines in the 

United States. This includes domestic and foreign producers of engines. In the case of imported 

products, this also includes equipment manufacturers and importers that import products containing engines certified by another manufacturer. 

The regulation includes provisions that allow certain manufacturers or importers to waive the 

bond requirements in certain circumstances. To be exempt from the bond requirements, a manufacturer would need to meet both the asset test and the repair-network test. Note that equipment manufacturers and importers may meet the bond requirements or obtain waivers of the 

bond requirements in conjunction with the certifying engine manufacturer. For example, if the 

certifying engine manufacturer passes the asset test and the repair-network test, or has met the 

bond requirements, all equipment manufacturers and importers that import those engines will 

be considered to be in compliance with the bond provisions in the regulations. 

The bond requirements apply with respect to engines that are subject to exhaust emission standards; they do not apply separately for fuel-system components or any other products relative to 

evaporative emission standards. 

What is the asset test for waiving bond requirements? 

The asset test is based on the understanding that manufacturers with substantial long-term assets in the United States are more likely able to meet any compliance- or enforcement-related

obligations. We have therefore adopted provisions to allow for waiving the bond requirements 

for manufacturers that have fixed assets in the United States meeting one of the following applicable thresholds: 

•	 $3 million – For manufacturers that have been certificate holders in each of the 

preceding ten years without failing a test conducted by EPA officials or having 

been found by EPA to be noncompliant under applicable regulations. 

•	 $6 million – For secondary engine manufacturers. A secondary engine manufacturer is generally a certifying manufacturer that buys partially complete 

engines for final assembly from another engine manufacturer. 

•	 $10 million – For manufacturers that do not qualify for the smaller specified bond 

thresholds. 

The value of long-term assets is based on the value from the manufacturer’s most recent balance 

sheet for buildings, land, and fixed equipment, after subtracting depreciation and related longterm liabilities (such as a mortgage) using Generally Accepted Accounting Principals (GAAP) 

or International Accounting Standards (IAS). 

What is the repair-network test for waiving bond requirements? 

The biggest indicator of a manufacturer’s ability to make warranty repairs is the presence of repair facilities in the United States. The regulations specify that manufacturers can demonstrate 

a readiness to meet warranty obligations by maintaining an adequate repair network. Such a repair network would need to involve at least 100 authorized repair facilities in the United States, 

or at least one such facility for each 5,000 engines sold in the United States, whichever is less. 

Does the bond requirement apply to engines if they are only sold in California? 

Yes, the bond requirement applies to all engines sold in the United States. 

If I need to meet the bond requirements, how do I determine the value of the bond? 

The value of the bond must be at least $500,000, though a higher bond value may apply based 

on multiplying the annual volume of shipments by a per-engine rate. In April of 2010, EPA 

issued an amendment to the bonding provisions to impose a maximum bond of $10 million 

dollars through 2012. This maximum value applies without adjustment for inflation. The perengine bond values are shown in the following table.

The total bond amount will be based on the value of imported products over a one-year period. 

For example, for total projected U.S.-directed production volumes of 10,000 engines with 180 

cc displacement and 10,000 engines with 400 cc displacement in a given calendar year, the calculated bond value is $750,000. This calculated value must be adjusted as follows:

•	 If estimated or actual U.S.-directed production volume increases beyond the 

 level appropriate for the currently held bond, the manufacturer must increase the 

 value of the bond to reflect the increased volume within 90 days. 

•	 You may not decrease the value of the bond. 

•	 The bond values (as well as the asset thresholds identified above) must be adjusted 

 for inflation based on the Consumer Price Index (CPI) published by the Bureau 

 of Labor Statistics. For example, 2010 bond values are adjusted by comparing the 

 CPI for June 2009 with the CPI for June 2008. Round calculated values for the 

 thresholds and for total bond obligations to the nearest thousand dollars. 

•	 For engines produced within the United States and shipped without aftertreat- 

 ment devices under the delegated-assembly provisions of 40 CFR 1054.610, the 

 calculated bond value must increase by 20 percent. 

The bond must remain in place for every year that a manufacturer or importer is selling or importing engines in the U.S. Additionally, the bond must remain in place for five years after the 

engine manufacturer no longer certifies Small SI engines (or after the equipment manufacturer 

or importer no longer imports Small SI engines). 

What information must I include in my application for certification?

The manufacturer must identify whether or not the bond requirement applies. If the bond requirement is waived, the manufacturer must provide basic information to demonstrate that the 

asset test and the repair-network test have been met. For example, the applications must include 

street addresses to identify the location of the relevant long-term assets. If a bond is required, 

the application must include an estimate of the value of the bond and a commitment to meet 

the bond requirement. It is not necessary to secure the bond before we can issue a certificate. 

What is a surety agent?

A surety agent is a party that provides a surety bond, such as those required to meet the bond 

requirements for Small SI engines. This is somewhat like an insurance company that is prepared 

to underwrite a policy to ensure that the manufacturer required to post a bond will be able to 

meet its obligations under the regulations. A sample bond form is attached to this fact sheet. 

The Surety & Fidelity Association of America (http://surety.org/) and the National Association of Surety Bond Producers (http://www.nasbp.org/) have an extensive set of information on 

surety bonds, both for an explanation about how surety bonds works (see especially http://surety.

org/content.cfm?lid=70&catid=2) and for help in finding a surety agent (see http://www.nasbp.

org/NASBP/NASBP/Directory/FindAProducer/Default.aspx). 
Frequently Asked Questions 

How much does it cost to get a bond? 

Each prospective surety agent will charge a fee for underwriting a bond. The costs related to 

this service are negotiated between the manufacturer and the surety agent. The surety agent 

will generally take into account the ability of the manufacturer to meet its obligations, from 

the perspective of current business practices and presence in the market as well as the financial 

standing to be able to meet potential monetary obligations. The surety agent might consider any 

number of factors in evaluating the risk that the bond might be needed for EPA compliance or 

enforcement actions. 

Part of the fee for underwriting the bond would also depend on the quantity and quality of collateral provided by the manufacturer. Manufacturers that have a well established history of compliance and a sound financial standing may need to provide minimal collateral to secure a bond 

at an agreed-on price. Manufacturers that represent a greater risk would likely need to provide 

substantial collateral for any surety agent to offer a bond at any price. A common example of 

collateral would be an escrow account held at a U.S. bank that could be accessed by the surety 

agent to cover bond amounts that are forfeited based on an EPA judgment for noncompliance.
