HS Code for Polyvinyl acetate dispersion

HS code 3905.12 is designated for polyvinyl acetate (PVA) in aqueous dispersion, in primary forms. In the context of the Harmonized System, an aqueous dispersion refers to a system where polymer particles are suspended in water, often stabilized by surfactants or protective colloids. This is commonly known as PVA emulsion or \"white glue\" in its raw, bulk state. The classification falls under Chapter 39, which covers plastics and polymers. To qualify for 3905.12, the product must be in a primary form as defined by Note 6 to Chapter 39 and must consist predominantly of vinyl acetate polymers. These dispersions are critical raw materials for the adhesive industry, particularly for wood and paper bonding, as well as for the textile industry as sizing agents. The classification is straightforward but requires confirmation that the medium is water-based. If the polymer were dissolved in an organic solvent or presented in a solid form, it would be excluded from this specific subheading and moved to 3905.19. Furthermore, if the dispersion has been modified with pigments and other additives to function as a paint or varnish, it would be classified under 3209.10. The distinction between a primary form polymer and a prepared coating or adhesive is a common point of contention in customs audits. 3905.12 is strictly for the polymer dispersion before it has been fully formulated into a consumer-ready product.

Products Included

• Aqueous polyvinyl acetate emulsions
• Bulk white wood glue (unformulated)
• PVA water-based binders for textiles
• Vinyl acetate polymer dispersions in water
• Liquid PVA primary forms

Common Misclassification

PVA dispersions are often misclassified under 3209.10, which covers paints and varnishes based on synthetic polymers dispersed in an aqueous medium. If the product contains pigments, it belongs in 3209. Another common error is using 3905.19, which is for non-aqueous or solid forms of PVA. Finally, if the dispersion is packaged for retail sale as a glue (under 1kg), it must be classified under 3506.10.

FAQ

What is the HS code for Polyvinyl acetate dispersion?

The HS code for polyvinyl acetate in aqueous dispersion is 3905.12.

Can 3905.12 be used for wood glue?

Yes, if the wood glue is a basic aqueous PVA dispersion in bulk primary form. If it is a complex formulation or in small retail packs, 3506 is used.
