On December 17, 2024, US EPA issued a final risk-management rule under TSCA section 6(a) prohibiting all uses of trichloroethylene (TCE), most of which would be prohibited within one year, including TCE manufacture and processing for most commercial and all consumer products. The final rule was originally scheduled to become effective on January 16, 2025, however the effective date was postponed due to petitions and legal filings until November 17, 2025.
EPA recently announced that it is extending the postponement of the effectiveness of certain regulatory provisions of the final rule for an additional 90 days until February 17, 2026.
