HS-4 · Heading
3905 — Polymers of vinyl acetate or of other vinyl esters, in primary forms; other vinyl polymers in primary forms
Chapter 39: Plastics and articles thereof
Plain-language overview
Use HS-4 3905 when importing or exporting polymers of vinyl acetate or other vinyl esters in primary forms. For example, if you're dealing with poly(vinyl acetate) in aqueous dispersion for adhesive applications, this heading is relevant.
When deciding between HS-6 390512 and 390519, consider the form of the poly(vinyl acetate). If your product is a water-based adhesive, use 390512. However, if it’s a solid form not in aqueous dispersion, 390519 is the correct choice.
For vinyl acetate copolymers, the distinction between HS-6 390521 and 390529 hinges on whether the product is in aqueous dispersion. If you have a copolymer in a water-based format, choose 390521; otherwise, opt for 390529.
If your product is poly(vinyl alcohol), it falls under HS-6 390530, regardless of whether it contains unhydrolyzed acetate groups. For other vinyl polymers not classified elsewhere, refer to HS-6 390591 or 390599 based on their copolymer status.
