On April 26, 2007, the Air Resources Board (ARB) approved an airborne toxic control measure (ATCM) to reduce formaldehyde emissions from composite wood products including hardwood plywood (HWPW), particleboard (PB), medium density fiberboard (MDF), and also furniture and other finished products made with composite wood products.

For manufacturers of HWPW, PB, and MDF, compliance with emission standards specified in the ATCM must be verified by using a third party certifier approved by ARB.  Third party certifiers are required to ensure that manufacturers of composite wood products verify compliance with the applicable emissions standards under the ATCM for their manufactured products.
