Which label indicates CARB approval status for aftermarket parts?

• A. Emissions Label
• B. CARB Approved Label
• C. Manufacturer Label
• D. Aftermarket Parts Label (APL)

Answer: (D)

In California, parts that affect emissions must be CARB-verified, and the sign that confirms that status is the Aftermarket Parts Label. This label is placed on the part or its packaging and shows that the part has CARB approval to be used legally in CA. It helps the inspector quickly verify that the component meets emissions standards and won’t cause a failure.

The Emissions Label on the vehicle is about the vehicle’s own emissions system as a whole, not about individual aftermarket parts. The Manufacturer Label identifies who made the part, but not its CARB approval status. A CARB Approved Label isn’t the standard label used to indicate verification for aftermarket components; the formal indication of CARB approval for aftermarket parts is the Aftermarket Parts Label.
