EPA proposes updates to incorporated voluntary consensus standards for TSCA Title VI formaldehyde emissions standards (incl. adding ISO 12460-2:2024 QC test method)

EPA issued a proposed rule to update the incorporation by reference (IBR) of multiple voluntary consensus standards in 40 CFR Part 770 (TSCA Title VI—Formaldehyde Emission Standards for Composite Wood Products). EPA also proposes adding ISO 12460-2:2024(en) as an additional small-scale quality control chamber test method and making related conforming updates (e.g., scope/definitions). Compliance teams in composite wood products and downstream supply chains should review whether current QA/QC testing methods and referenced standards would need updating if the rule is finalized, and should consider submitting comments to the docket by the stated deadline (March 13, 2026).
