The recognition allows SEMA to offer certification-level automotive exhaust emissions testing to help members develop products for all 50 states. Testing plays a vital role in the CARB Executive Order (EO) process, particularly for products that may impact vehicle emissions.

Keeping up to date on regulations such as the federal Clean Air Act and the California Vehicle Code allows SEMA to offer knowledge to assist companies with compliance by offering emissions testing services and aiding in navigating regulatory standards. 

This support enables manufacturers to efficiently test, develop, certify and bring their products to market. As of February 2024, there were only 14 Independent Vehicle Emissions Testing Labs in the United States, including the two SEMA Garages, recognized by CARB to perform light-duty tailpipe emissions testing.

“The emissions testing labs at the SEMA Garage in Detroit and Diamond Bar focus on developing and certifying aftermarket components,” said Ben Kaminsky, general manager, SEMA Garage Detroit.

Opened in 2022, the SEMA Garage Detroit emissions lab offers comprehensive services, including cutting-edge emissions tools, competitive rates, assistance with vehicle procurement, and real-time observation of testing by manufacturers. 

The SEMA Garage Compliance Center can assist manufacturers throughout the entire CARB application process, further streamlining the path to regulatory approval.

The facility also features an Advanced Driver-Assistance Systems (ADAS) Center and offers Original Equipment Manufacturer (OEM) measuring sessions, scanning services, and tools and equipment.

The SEMA emissions and compliance teams are dedicated full-time staff who guide members through the CARB EO application and testing requirements, offering support in communication with CARB every step of the way. SEMA has secured more than 700 CARB EOs for its members. 

SEMA also offers its SEMA Certified Emissions program that meets the requirements of the EPA’s Tampering policy, helping manufacturers sell confidently in 49 states.

Located in Plymouth, Michigan, and Diamond Bar, California, SEMA Garage services are available to all SEMA members. For more information, visit
