On April 26, 2007, the California Air Resources Board approved a regulation to reduce formaldehyde emissions from composite wood products that are sold, supplied, used, or manufactured for sale in California. The regulation focuses on hardwood plywood (HWPW), particleboard (PB), and medium density fiberboard (MDF). The regulation requires that HWPW, PB, and MDF and new finished goods that contain these composite wood products meet stringent emission standards and be labeled as such.
