The California Air Resources Board “Airborne Toxic Control Measure to Reduce Formaldehyde Emissions from Composite Wood Products” (CARB Rule) is the toughest production standard of its kind in the world and the model for EPA’s national regulation, TSCA Title VI.  Initially approved in May 2007, CPA worked closely with the CARB in supporting its development and initial implementation.  The North American composite panel industry also made voluntary investments in technology, quality assurance and third-party verification programs in order to meet the state’s stringent formaldehyde standards for all 50 states, even though the regulations only applied in California. 

CPA has provided longstanding support for CARB’s strong regulatory enforcement to protect consumers and ensure a level playing field for manufacturers around the world. CPA also continues to work with California regulators on subsequent updates and amendments to this rule, actively supporting future amendments that better align the CARB rule with TSCA Title VI.   CARB is expected to propose new amendments in late 2019.
