9902.08.45 - Reduced Vat Blue 1 ([2,2'-Bi-1H-indole]-3,3'-diol, potassium sodium salt) (CAS No. 207692-02-2) (provided for in subheading 3204.15.40)

This HTS category, 9902.08.45, specifically covers Reduced Vat Blue 1, also known by its chemical name [2,2'-Bi-1H-indole]-3,3'-diol, potassium sodium salt (CAS No. 207692-02-2). This classification is temporary and is established under Section XXII of the Harmonized Tariff Schedule, pertaining to special classification provisions, temporary legislation, and import restrictions proclaimed under specific trade agreements and agricultural acts. The "provided for in subheading 3204.15.40" note indicates that this substance, when not subject to these temporary provisions, would typically fall under the dyes and pigments classification.

As a temporary provision within Chapter 99, this code differentiates specific items from their more general or permanent classifications. Unlike sibling categories which might cover a broad range of live animals or other goods under the general HTS structure, this node is highly specific to a particular chemical compound. Its existence signifies a unique regulatory treatment, likely due to trade policy, agricultural protection, or temporary market management measures, rather than inherent material or functional differences that would distinguish it from products in unrelated chapters.

Since HTS 9902.08.45 is a leaf node, it does not have further subcategories. This means that any import of Reduced Vat Blue 1, when subject to the temporary legislation indicated by its presence in Chapter 99, will be classified directly under this specific code. Classification into this category hinges entirely on whether the imported product is identified as Reduced Vat Blue 1 and whether the prevailing trade conditions warrant its application under these special provisions.
