Last updated: April 2026 dataTrichloroethylene (TCE) is a high-solvency degreasing agent widely used in metal fabrication, electronics cleaning, and aerospace maintenance, classified under a single 10-digit line (2903220000). China is the dominant US import source, with Japan and Germany also supplying the market. EPA has designated TCE a carcinogen and has pursued restrictions on its industrial use under TSCA, so importers must monitor evolving use prohibitions and ensure TSCA certification is filed at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
EPA has taken regulatory action under TSCA to restrict or prohibit certain industrial uses of TCE due to its carcinogenicity. Importers should verify current use restrictions before contracting supply, as prohibited end-uses can affect admissibility and downstream liability even if the import itself clears customs.
Trichloroethylene (three chlorine atoms, HTS 290322) and tetrachloroethylene/perchloroethylene (four chlorine atoms, HTS 290323) are distinct chemical compounds with separate headings. The distinction matters not only for duty purposes but also because their EPA regulatory treatment and primary end-use sectors differ.
