HS Code for Vinyl acetate copolymer emulsion

Vinyl acetate copolymer emulsions are classified under HS code 3905.21. These products are defined as copolymers of vinyl acetate in primary forms, specifically in aqueous dispersion. In the context of the Harmonized System, "primary forms" include liquids and pastes, including dispersions (emulsions and suspensions) and solutions. Heading 3905 covers polymers of vinyl acetate, and the subheadings are divided based on whether the product is a homopolymer or a copolymer, and then by its physical state. An aqueous dispersion means the polymer particles are suspended in water, often with the help of surfactants or protective colloids. These emulsions are commonly used as the base for wood glues, paper adhesives, and architectural coatings. The classification follows GRI 1 and 6, relying on the specific description of the copolymer's physical delivery system (water-based) as the primary determinant for the 3905.21 code.

Products Included

• Vinyl acetate-ethylene (VAE) emulsions
• Vinyl acetate-acrylic copolymer dispersions
• Water-based wood adhesives (white glue)
• Aqueous dispersions used in paint formulations
• Vinyl acetate-dibutyl maleate copolymer emulsions

Common Misclassification

This product is often confused with HS code 3209.10, which covers paints and varnishes based on acrylic or vinyl polymers dispersed in an aqueous medium. The distinction depends on whether the product is a "primary form" (raw material) or a finished "prepared" coating with added pigments and fillers. Another common misclassification is 3905.11, which is for polyvinyl acetate homopolymers in aqueous dispersion. If the polymer contains any amount of another monomer (like ethylene or butyl acrylate) that is not merely an impurity, it must be classified as a copolymer under 3905.21.

FAQ

What is the HS code for Vinyl acetate copolymer emulsion?

The HS code for vinyl acetate copolymers in aqueous dispersion (emulsion) is 3905.21.

Can this code be used for finished adhesives?

If the emulsion is a simple primary form, 3905.21 applies. However, if it is a complex formulated adhesive with multiple additives packaged for retail sale, it may fall under HS code 3506.
