EPA Finalises Formaldehyde Standards Update for Composite Wood Products
Reference source : US EPA
New Testing Method Added to Emissions Framework
The U.S. Environmental Protection Agency (EPA) has finalised updates to its Formaldehyde Emission Standards for Composite Wood Products, introducing a new internationally recognised test method for measuring formaldehyde emissions from wood-based materials. The revision forms part of the agency's ongoing efforts to keep regulatory requirements aligned with current scientific and industry standards.
The newly approved method, ISO 12460-2:2024, provides manufacturers and testing laboratories with an additional quality-control tool for determining formaldehyde emissions from composite wood products. EPA stated that the update will help improve consistency, reliability and comparability of emissions data across the industry.
Alignment with International Standards
Alongside the introduction of the new ISO method, EPA has updated several voluntary consensus standards referenced in the regulation. The changes align the rule with the latest standards developed by organisations including the American National Standards Institute (ANSI), ASTM International, the British Standards Institution (BSI), the International Organization for Standardization (ISO) and the National Institute of Standards and Technology (NIST).
The revised standards cover testing methods and product specifications for plywood, laminated timber and wood-based panels commonly used in construction and furniture manufacturing.
No Changes to Existing Safety Requirements
EPA emphasised that the amendments are technical updates and do not alter existing formaldehyde emission limits or health protections for consumers and workers. The agency also clarified that the revisions are separate from its ongoing TSCA risk evaluation for formaldehyde.
Formaldehyde is widely used in adhesives and resins found in products such as furniture, flooring, cabinetry, plywood and other engineered wood materials. Federal emission standards were originally established under the Formaldehyde Standards for Composite Wood Products Act of 2010 to reduce indoor air exposure and protect public health.
Greater Clarity for Industry
According to EPA, the latest updates will help maintain consistency with current manufacturing practices while providing greater regulatory clarity for manufacturers, testing laboratories and certification bodies. The agency noted that this marks the fourth update to the rule's voluntary consensus standards since the original regulation was finalised in 2016.
