9902.08.52 - Reactive Yellow F00-0155 (1H-Xantheno[2,1,9-def]isoquinoline-5,9-disulfonic acid, 2,3-dihydro-1,3-dioxo-2-[3-[[2-(sulfooxy)ethyl]sulfonyl]phenyl]-, sodium salt (1:?:?)) (CAS No. 1309975-18-5) (provided for in 3204.16.30)

This HTS code, 9902.08.52, specifically covers "Reactive Yellow F00-0155," a particular chemical compound identified by its chemical name and CAS number. This entry falls under Chapter 99, which is reserved for temporary legislation, temporary modifications to trade agreements, and restrictions imposed under Section 22 of the Agricultural Adjustment Act. Therefore, the classification of Reactive Yellow F00-0155 under this code signifies a specific, temporary control or provision applied to this particular dye, overriding its standard classification.

The inclusion of "provided for in 3204.16.30" in the description is crucial. It indicates that, absent these temporary provisions, Reactive Yellow F00-0155 would typically be classified under HTS heading 3204.16.30, which pertains to reactive dyes and preparations thereof. The Chapter 99 classification therefore represents a deviation from this standard treatment, likely due to import quotas, temporary duty adjustments, or other trade policy measures.

As a leaf node, 9902.08.52 has no further subcategories. Its scope is precisely defined by the chemical name and the temporary legislative context. Classification within this node is determined by the precise identity of the substance as Reactive Yellow F00-0155, and the applicable temporary regulations in force under Chapter 99 at the time of import. Importers must consult current trade notices and regulations pertaining to this specific HTS code to understand the full implications for entry.
