9902.08.47 - Vat Blue 4 (6,15-dihydro-5,9,14,18-anthrazinetetrone) (CAS No. 81-77-6) (provided for in subheading 3204.15.80)

This classification, HTS Code 9902.08.47, pertains to a specific chemical compound: Vat Blue 4, also known by its chemical name 6,15-dihydro-5,9,14,18-anthrazinetetrone. This designation is applied under Chapter 99 of the Harmonized Tariff Schedule, which covers temporary legislation and special provisions, including those related to agricultural import restrictions. The inclusion of the CAS Number (81-77-6) and a reference to its placement within subheading 3204.15.80 highlights that this entry is a specific temporary modification or restriction affecting a product otherwise classified as a synthetic dyestuff.

Given that this is a leaf node within Chapter 99, there are no further subdivisions. The unique nature of Chapter 99 categories means they do not have direct sibling classifications in the traditional sense of product categories like live animals or manufactured goods. Instead, they represent specific, often temporary, legislative actions or limitations applied to goods that might otherwise fall under different chapters of the HTS. Therefore, this entry is distinguished by its specific designation as Vat Blue 4 under a special provision, rather than by comparison to other, unrelated product groups at the same structural level. The primary function of this classification is to implement specific trade policy or regulatory measures on this particular chemical compound.
