U.S. imports of vinyl acetate copolymers in aqueous dispersion (HS 390521) totaled $4.1M in August 2026, imported from 18 countries.
Importers of Vinyl Acetate Copolymers in Aqueous Dispersion paid $69K in duties in August 2026, an effective tariff rate of 1.68% of the $4.1M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataVinyl acetate copolymers in aqueous dispersion — most commonly ethylene-vinyl acetate (EVA) or vinyl acetate-acrylic emulsions — are widely used as binders in paints, coatings, textile finishing, and construction adhesives, where their water-based form simplifies application and reduces VOC emissions. Classified under a single US tariff line (3905210000), these copolymers are distinguished from homopolymer PVAc dispersions by the presence of a co-monomer that modifies flexibility, adhesion, or water resistance. Canada and Mexico are the leading import sources, positioning USMCA as a relevant framework for duty treatment in North American supply chains.

An EVA dispersion is a copolymer containing both ethylene and vinyl acetate repeat units and classifies under 390521, while a pure PVAc dispersion (homopolymer) classifies under 390512. The co-monomer identity and weight percentage, confirmed by the manufacturer's specification sheet, are the determining factors.
While aqueous polymer dispersions are not subject to FDA or FSIS review, they may require Safety Data Sheets (SDS) under OSHA Hazard Communication standards if they contain hazardous components. For customs entry, the commercial invoice should specify the polymer type, solids content, and co-monomer composition to support correct classification and valuation.
