9902.08.42 - Vat blue 66 (9,10-Anthracenedione,1,1ʹ-[(6-phenyl- 1,3,5-triazine-2,4-diyl)diimino]bis(3ʺ-acetyl-4-amino-)) (CAS No. 32220-82-9) (provided for in subheading 3204.15.30).

This HTS classification, 9902.08.42, specifically designates Vat blue 66, identified by its chemical name (9,10-Anthracenedione, 1,1ʹ-[(6-phenyl-1,3,5-triazine-2,4-diyl)diimino]bis(3ʺ-acetyl-4-amino-)) and CAS Number 32220-82-9. While the general material falls under Chapter 3204.15.30 concerning organic dye preparations, this particular subheading within Chapter 99 signifies a temporary legislative provision. This means that imports of Vat blue 66 are subject to specific, often temporary, trade agreement modifications or additional import restrictions as proclaimed under Section 22 of the Agricultural Adjustment Act.

Given that this is a leaf node, there are no further subcategories. The primary distinction for this classification lies in its inclusion within Chapter 99, indicating its status as a special provision rather than a standard product classification found in earlier chapters. This implies that importers must be aware of any specific proclamations, quotas, or additional duties that may apply solely to Vat blue 66, overriding its standard tariff treatment under Chapter 32. The classification ensures that these specific temporary measures are applied correctly at the point of entry.
