U.S. imports of vinyl chloride–vinyl acetate copolymers in primary forms (HS 390430) totaled $3.6M in April 2026, traded with 10 countries.
Importers of Vinyl Chloride–Vinyl Acetate Copolymers in Primary Forms paid $448K in duties in April 2026 — an effective duty rate of 14% on $3.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataVinyl chloride–vinyl acetate (VC/VAc) copolymers are specialty resins where the vinyl acetate content modifies solubility, adhesion, and film-forming properties relative to pure PVC, making them widely used in surface coatings, adhesives, and vinyl flooring binders. The US schedule distinguishes vinyl acetate–vinyl chloride–ethylene terpolymers containing less than 50% vinyl acetate by weight (3904302000) from all other VC/VAc copolymers (3904306000). Germany is the leading supplier, consistent with its strong specialty polymer industry, with Thailand and Japan also significant sources.

The US schedule splits VC/VAc copolymers at the 50% vinyl acetate by weight threshold: terpolymers containing vinyl acetate, vinyl chloride, and ethylene with less than 50% vinyl acetate fall under 3904302000, while all other VC/VAc copolymers — including standard two-component grades — are classified under 3904306000. Importers must obtain monomer composition data from suppliers to determine the correct 10-digit line.
Unlike homopolymer PVC, VC/VAc copolymers are soluble in common organic solvents and have lower softening points, which makes them suitable for solution-applied coatings and adhesives where PVC would be impractical. Procurement teams should specify the vinyl acetate content range and molecular weight in purchase orders, as these parameters directly affect solution viscosity and film properties in end-use applications.
