Last updated: August 2026 dataVinyl chloride monomer (VCM) is the foundational feedstock for polyvinyl chloride (PVC) resin, making it a critical upstream input for the construction, packaging, and automotive sectors. Classified under a single 10-digit line (2903210000), US imports originate primarily from China, with South Korea as a secondary source. Because vinyl chloride is a known human carcinogen, shipments are subject to OSHA hazard communication requirements and EPA Toxic Substances Control Act (TSCA) reporting obligations at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Importers must comply with EPA TSCA Section 13 certification requirements, confirming the substance either complies with TSCA or is not subject to it. Given vinyl chloride's carcinogen classification, additional reporting under TSCA Section 8(e) may be triggered if new risk information arises during transit or handling.
Vinyl chloride (chloroethylene) has its own dedicated HS6 heading (290321) and a single 10-digit line, distinct from trichloroethylene (290322) and tetrachloroethylene (290323). Misclassification can result in incorrect duty assessment and missed compliance obligations, since each compound carries different regulatory and hazard profiles.
