New SEMA Emissions Certification Program Helps Manufactures Get Products to Market Faster

220201 The new SEMA Certified-Emissions program (678)

First-ever program meets EPA’s Tampering Policy requirements

DIAMOND BAR, CA – February 1, 2022 – (Motor Sports NewsWire) – SEMA introduced a new program to make it possible for automotive aftermarket parts manufacturers to meet the legal requirement for emissions compliance under the Environmental Protection Agency’s (EPA) Tampering Policy. The program, called SEMA Certified-Emissions (SC-E), gives manufacturers the ability to verify that a product meets the EPA’s “reasonable basis” criteria and is therefore legal for sale in 49 states.

For the first time ever, manufacturers have a clear, accelerated path to compliance and can begin selling products legally in 49 states prior to receiving a California Air Resources Board (CARB) Executive Order (EO), which is still a requirement for selling products in all 50 states.

“It’s now easier than ever for manufacturers to demonstrate emissions compliance,” said Mike Spagnola, SEMA VP of OEM & Product Development Programs. “SEMA Certified-Emissions is a major accomplishment in accelerating a manufacturer’s ability to get products to market, and it paves the path to obtaining emissions compliance in all 50 states.”

Since 2014, the SEMA Garage has been instrumental in helping automotive aftermarket parts manufacturers obtain CARB EOs. With state-of-the-art CARB-recognized testing equipment and dedicated expert staff conducting tests and assisting with the process, the SEMA Garage has helped secure more than 500 CARB EOs – over half of all performance parts EOs issued by CARB.

The new SC-E program is comparable to CARB EO requirements and was developed in response to the EPA’s Tampering Policy. SEMA staff will assess manufacturer’s needs and advise as to the most appropriate path forward, whether that includes applying for a CARB EO or SEMA emissions certification.  SC-E may help manufacturers get to market about three months before obtaining a CARB EO. SC-E is also ideal for products that may not have a clear path in the CARB EO process (such as Flex-Fuel modifications, HCT equipped intakes, and engine packages).

“SC-E gives manufacturers much greater options and opportunities,” said Peter Treydte, SEMA Director of Emissions Compliance. “This is a significant milestone in the industry’s ability to provide products to consumers. We look forward to working with members and helping them go to market with SEMA Certified-Emissions products.”

The SEMA Garage is available to auto parts manufacturers with all their product development needs. For more information, visit
