About this product:
Dear SEMA Member,
Over the years, SEMA has received many requests from members seeking information about federal and state emissions compliance requirements. If you manufacture emissions-related aftermarket parts for regulated vehicles, the parts will likely need to be tested to confirm that vehicles will still meet applicable clean air standards after the part has been installed. Emissions-related parts are regulated under our Nation’s clean air laws and are primarily enforced by two government agencies: the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB).
SEMA wants to give you all the tools necessary to comply with the law in a cost-effective manner. That includes explaining the law and providing an option to test your products. Emissions-related aftermarket parts include any specialty part that interacts with the vehicle’s emissions system and changes the performance levels of the equipment being replaced or supplemented. They are commonly called “add-on” or “modified” parts. The product may be “emissions-related” if it is installed anywhere between the air intake and the outlet end of the catalytic converter. The term does not include ordinary replacement parts.
The information contained in this document is intended as a complete guide for any interested party to understand the emissions compliance process and to maximize the probability of a successful compliance experience. SEMA has a staff available to assist members throughout the process. Contact information is provided at the end of this document. We encourage you to contact us with any questions pertaining to the compliance process.
