Last updated: April 2026 dataPerchloroethylene (PERC) is the dominant solvent in commercial dry cleaning and a key degreasing agent in industrial metal finishing, entering under a single 10-digit line (2903230000). Germany and the Czech Republic are the leading US import sources, reflecting strong European production capacity for this compound. Like trichloroethylene, PERC is subject to EPA TSCA scrutiny as a probable human carcinogen, and importers should track any evolving use restrictions that could affect downstream customer eligibility.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Both countries host established chlorinated solvent manufacturing infrastructure with long-standing export relationships. European producers have historically maintained quality consistency and regulatory compliance documentation that US industrial buyers require, giving them a competitive edge over more distant suppliers.
Importers must file a TSCA Section 13 certification confirming compliance or exemption. Safety Data Sheets (SDS) meeting OSHA HazCom standards are required for hazardous chemical shipments. If the shipment is destined for dry-cleaning end-use, buyers should also be aware of state-level restrictions on PERC that may affect resale.
