3209.90.00.00 - Other

This HTS classification, 3209.90.00.00, covers paints, varnishes, and similar coatings that are based on synthetic polymers or chemically modified natural polymers and are dispersed or dissolved in an aqueous medium. Crucially, this category encompasses products that do not fall under the more specific subcategory of acrylic or vinyl polymer-based coatings. Therefore, the primary distinguishing factor from its sibling category (3209.10.00.00) lies in the chemical nature of the base polymer.

Goods classified under 3209.90.00.00 would include water-based paints and varnishes where the primary film-forming binder is derived from polymers other than acrylics or vinyls. Examples might include water-based polyurethane coatings, alkyd emulsions, or certain epoxy-based waterborne coatings. The defining characteristic remains the aqueous dispersion or solution, as opposed to solvent-based formulations, and the absence of acrylic or vinyl polymers as the principal synthetic or modified natural polymer.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification into this code is determined by meeting the general criteria for Chapter 32 paints and varnishes (water-based, synthetic or chemically modified natural polymers) and specifically by *not* fitting the criteria for the "acrylic or vinyl polymers" sibling category. Careful consideration of the polymer composition is essential for accurate classification.
