U.S. imports of Vinyl Chloride–Vinyl Acetate Copolymers, Primary Forms (SITC 57391) totaled $5.4M in August 2026, imported from 10 countries.
Importers of Vinyl Chloride–Vinyl Acetate Copolymers, Primary Forms paid $732K in duties in August 2026, an average duty rate of 13.70% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Vinyl Chloride–Vinyl Acetate Copolymers, Primary Forms imports of $5.4M in August 2026 ran 33% above the year-to-date monthly average of $4.1M.
Last updated: August 2026 dataVinyl chloride–vinyl acetate (VC/VAc) copolymers are widely used in coatings, adhesives, and flooring binders, where the vinyl acetate content modifies solubility and adhesion relative to homopolymer PVC. The ratio of vinyl chloride to vinyl acetate monomer units is the critical specification that determines both end-use suitability and correct tariff classification. Suppliers in Asia, particularly China, are significant sources, making Section 301 tariff exposure a routine cost consideration for US compounders and formulators.

Customs classification typically requires the weight percentage of each monomer unit. The vinyl acetate content in particular can shift classification between vinyl chloride copolymer headings and other polymer categories, so a technical data sheet or certificate of analysis should accompany the entry.
VC/VAc copolymers are primary inputs for solvent-based coatings, heat-seal lacquers, vinyl flooring adhesives, and magnetic tape binders. Their balance of chemical resistance and adhesion makes them preferred over straight PVC in formulations requiring solubility in ketone or ester solvents.
