For Amazon sellers that list products that need an EPA Certificate of Conformity, the due date to submit is October 18, 2022. Continue reading to understand the process of obtaining the certification.

What is the EPA Certificate of Conformity

The US Environmental Protection Agency (EPA) Certificate of Conformity (COC) is a compliance requirement set forth by the Clean Air Act. It requires manufacturers or importers of fuel-powered engines to comply with federal emissions prior to being sold in the United States. These are the same regulations required for any vehicle, engine, or method of transportation sold in the United States.

Compliance with these regulations is essential to attaining air quality in the United States. Obtaining the COC means that the engine or vehicle has gone through regulated testing and conforms to all emission requirements.

How to Obtain the EPA Certificate of Conformity

There is a list of certification data that sellers can find on the EPA’s website. Sellers will need to know the engine family number, engine type, and model year to locate the information. The database dates to model years from 1998.

If for any reason a seller cannot locate their required number in the database, sellers are advised to reach out to the EPA’s Import Hotline. The hotline can be reached via email at; fax to 734-214-4676; or phone to 734-214-4100.

Consequences for Not Obtaining the EPA Certificate of Conformity

If you’re a seller who has product listings that require an EPA Certification and Amazon doesn’t receive it by October 18, 2022, any new or existing listings are subject to removal. Amazon doesn’t need a physical certificate to meet its requirements. Sellers can submit a valid EPA COC number or a California Air Resources Board Executive Order (CARB EO) number. Until the valid certification numbers are received, those sellers’ products will not be listed on Amazon.

Sellers can find more information about submitting the COC in their Seller Central Account to review Amazon’s full requirements.
