2922.29.08.00 - Other

This HTS classification, 2922.29.08.00, specifically addresses certain amino-naphthols and amino-phenols that do not fall under more specific subheadings within this group. The defining characteristic of goods classified here is their molecular structure, which includes both an amine group and at least one hydroxyl group attached to an aromatic naphthol or phenol ring, and crucially, does not contain multiple different oxygen-containing functional groups beyond what is implied by the naphthol or phenol structure. Their salts and ethers are also included.

This "Other" category serves as a residual classification for amino-naphthols and amino-phenols not otherwise specified. It is distinguished from the sibling category 2922.29.06.00, which is exclusively for "Fast color bases." Fast color bases are a specific subset of amino-naphthols and amino-phenols that are primarily utilized as intermediates in the production of azo dyes, where their chemical properties are tailored for coupling reactions that yield specific colorfast properties. Consequently, goods classified under 2922.29.08.00 are those amino-naphthols and amino-phenols that, while possessing the basic structural features, are not designated for or primarily used as fast color bases.

As this is a leaf node, there are no further subcategories to introduce. Classification at this level is dependent on confirming that the imported substance is an amino-naphthol or amino-phenol meeting the general criteria and is not specifically classified as a fast color base or under any other more specific tariff provision. The focus for classification rests on the precise chemical structure and the intended commercial application if it deviates from the common use of fast color bases.
