3209.10.00.00 - Based on acrylic or vinyl polymers

This HTS category, 3209.10.00.00, specifically classifies paints, varnishes, enamels, and lacquers that are based on acrylic or vinyl polymers. These products are characterized by being dispersed or dissolved in an aqueous medium, meaning water is the primary solvent. This includes a wide range of decorative and protective coatings for various surfaces, such as architectural paints, interior and exterior wall coatings, and certain types of industrial finishes where the binder is an acrylic or vinyl polymer.

It is important to distinguish this subcategory from its sibling, 3209.90.00.00, which covers "Other" paints and varnishes based on synthetic polymers or chemically modified natural polymers in an aqueous medium. Therefore, 3209.10.00.00 is reserved exclusively for those products where the synthetic polymer binder is either an acrylic or a vinyl polymer. Any water-based coatings using other synthetic polymers (e.g., alkyds, polyurethanes not otherwise specified) or chemically modified natural polymers would fall under the "Other" category.

As a leaf node in the HTS structure, 3209.10.00.00 does not have further subcategories. Classification at this level hinges on the precise identification of the polymer base (acrylic or vinyl) and the aqueous nature of the dispersion or solution. Importers and exporters should ensure their product documentation accurately reflects the polymer composition to facilitate correct customs declarations and avoid potential discrepancies.
