Starting January 1, 2009, California will begin 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.  All products containing composite wood products must comply with the new regulation.

To help producers and consumers understand and comply with this rule, the Composite Panel Association (CPA) has created this site to provide information on the rule.

Informational documents explaining the rule, customer fact sheets, and Frequently Asked Questions are all provided on our Resources and Documents About the Rule 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 & Compliance Certification page.

Finally, visit our Links page to find contact information for CARB and other associations working with CPA on the implementation of the rule.

If you have a specific question that is not addressed in the materials on this site, please contact the CPA staff for immediate assistance.
