Looking to Achieve ATCM Compliance from an Approved CARB Certification Lab?

In order to sell a product containing composite wood in the state of California, compliance with the California Air Resources Board’s (CARB) Airborne Toxic Control Measure (ATCM) is required. Designed to reduce formaldehyde emissions from composite wood products and any finished products that contain them, the ATCM sets forth emissions limits for hardwood plywood (HWPW), particle board (PB), and medium density fiberboard (MDF).

UL is an approved Third Party Certifier of the California Air Resources Board, meaning that UL is authorized to conduct inspections and testing to assess composite wood panel manufacturers’ products for compliance to the regulation. In the certification process, UL verifies that the manufacturing facilities for subject composite wood products are capable of complying with the ATCM’s emission standards. To receive CARB Certification, manufacturers undergo quarterly inspections and testing, and routine quality control testing at manufacturing locations. Manufacturers that earn this certification demonstrate that their panels comply with the emission standards by labeling their panels as CARB Phase 2 compliant.

Certification ensures compliance with the ATCM and establishes a starting point for understanding a product’s emissions and opportunities to offer lower emitting products that contribute to healthier indoor environments.
