Your Resource for California ATCM compliance
Starting January 1, 2009, California began regulating the formaldehyde emissions from composite wood products (particleboard, MDF, and hardwood plywood) sold in the state or used to make finished goods offered for sale in the state of California. The Airborne Toxic Control Measure (ATCM) is known as the "CARB rule." All products containing composite wood products must comply with the regulation.
Informational documents explaining the rule, customer fact sheets, and Frequently Asked Questions are all provided on our Resources page. This should be your first stop if you're looking for information on the CARB rule.
CPA was the first Third Party Certifier (TPC) in the world to be approved by CARB and is now certifying manufacturers to CARB. Fabricators looking for a list of CARB certified panel producers and those domestic composite panel manufacturers interested in CARB certification should visit our Testing & Certification and Standards pages.
Finally, visit our Links page to find contact information for CARB and other associations working with CPA on the implementation of the rule.
