EPA is issuing a final rule to implement the Formaldehyde Standards for Composite Wood Products Act, which added Title VI to the Toxic Substances Control Act (TSCA). The purpose of TSCA Title VI is to reduce formaldehyde emissions from composite wood products, which will reduce exposures to formaldehyde and result in benefits from avoided adverse health effects. This final rule includes formaldehyde emission standards applicable to hardwood plywood, medium-density fiberboard, and particleboard, and finished goods containing these products, that are sold, supplied, offered for sale, or manufactured (including imported) in the United States. This final rule includes provisions relating to, among other things, laminated products, products made with no-added formaldehyde resins or ultra low-emitting formaldehyde resins, testing requirements, product labeling, chain of custody documentation and other recordkeeping requirements, enforcement, import certification, and product inventory sell-through provisions, including a product stockpiling prohibition. This final rule also establishes a third-party certification program for hardwood plywood, medium-density fiberboard, and particleboard and includes procedures for the accreditation of third-party certifiers and general requirements for accreditation bodies and third-party certifiers.
