CARB Certification is verification, by a third party certification body, that composite wood products comply with formaldehyde emissions standards

Intertek is approved by the California Air Resources Board (CARB) as a Third Party Certifier (TPC) under the Airborne Toxic Control Measure (ATCM), which aims to reduce formaldehyde emissions from composite wood products. Intertek is qualified to perform an extensive range of services related to CARB certification, including:

  • Formaldehyde emission testing on wood panel and finished goods
  • Establishing Quality Control Limits
  • Qualifying factory personnel
  • Review of quality control manuals
  • Factory audits
  • Labeling review for manufacturers and fabricators

The ATCM places different roles and obligations to panel manufacturers, distributors, importers, fabricators, as well as retailers.

The ATCM regulation consists of two phases of emission standards (see table 1 below), and requires good documentation control on the production quality management and formaldehyde emission standard compliance. To ensure compliance with the ATCM, panel manufacturers must be "third party certified" using a TPC, such as Intertek approved by the CARB. This involves independent emission testing of panels and factory audit of the manufacturing processes for manufacturers that sell or supply products to California.

Finished goods manufactured before the phase 1 and 2 effective dates containing HWPW-VC, HWPWCC, PB, MDF, or thin MDF may be sold, supplied, offered for sale for specified periods after the effective dates.

The ATCM will be enforced by the CARB or local air district personnel. Enforcement activities include facility inspections, auditing of records, and securing samples for compliance testing.
