3212.90.00 - Other

This HTS category, 3212.90.00, encompasses "Other" pigments, dyes, and coloring matter that are not specifically classified elsewhere within heading 3212. This typically includes finely divided solid coloring matter dispersed in a non-aqueous medium, such as liquid or paste, intended for use in the manufacture of paints and enamels. The key characteristic is their form and intended application as a component in paint production, rather than as finished paints themselves.

Within heading 3212, this "Other" category serves as a residual classification. It is distinct from the sibling category 3212.10.00.00, which specifically covers stamping foils. Stamping foils are typically thin films with a colored or metallic coating applied to a carrier material, used for decorative or marking purposes through a hot-stamping process, and thus have a different physical form and application than the dispersed pigments classified here.

The subcategories within 3212.90.00 further refine this classification based on the specific material of the pigment. 3212.90.00.10 specifically addresses metallic aluminum pigments, recognizing their distinct properties and widespread use. The remaining items fall under 3212.90.00.50, designated as "Other," which would include pigments dispersed in non-aqueous media made from materials other than aluminum, such as iron oxides, titanium dioxide (when dispersed as a pigment precursor), or organic pigments.
