2922.29.06.00 - Fast color bases

This HTS category, specifically 2922.29.06.00, encompasses "Fast color bases." These are a type of amino-naphthol or amino-phenol derivative, characterized by their functional groups and suitability for use in the synthesis of dyes and pigments. The term "fast color" refers to their property of producing colors that are resistant to fading from light, washing, or other forms of degradation. They are essentially intermediates used to create vibrant and durable coloration.

Within the broader group of "Other" amino-naphthols and amino-phenols, this specific heading distinguishes itself by referring to a particular subset of these compounds that are designated and utilized as "fast color bases." While other compounds within the 2922.29 subheading may also possess amino and hydroxyl functionalities on a naphthol or phenol ring, their intended application or specific chemical structure does not classify them as fast color bases. This distinction is crucial for proper tariff classification and is often determined by chemical nomenclature and intended commercial use.

As this is a leaf node, there are no further subcategories under 2922.29.06.00. Classification at this level is definitive, and goods falling under this description will not be further broken down within the HTS. Therefore, the primary classification criteria rely on the chemical identification of the substance as an amino-naphthol or amino-phenol that is commercially recognized and traded as a "fast color base" precursor for the dye industry.
