Structural engineered wood products exempt from new EPA formaldehyde ruling

June 19, 2018

Composite wood products must meet new U.S. Environmental Protection Agency (EPA) formaldehyde emissions regulations as of June 1, 2018.

Among the products impacted: particleboard, medium density fiberboard (MDF), and hardwood (decorative) plywood. Structural engineered wood products manufactured for construction applications, such as structural plywood, oriented strand board (OSB), wood I-joists, laminated veneer lumber, and glued-laminated timber, are exempt from the regulation.

Structural engineered wood products marked with the APA Mark of Quality are exempt from the regulation. In cases where unmarked structural engineered wood products from APA member mills are sold into industrial applications that do not require a certification mark, the product invoice and an APA certificate of conformance can be used to identify the product as exempt.

Certification of compliance is required to be completed by a Third Party Certifier, who will verify that the regulated composite wood product’s manufacturer is capable of complying with the emission regulation. Quarterly inspections and testing, and reviews of routine quality testing conducted at each mill are also required.
