9902.04.60 - 1,1'-(1,3-Phenylene)bis(1H-pyrrole-2,5-dione) (CAS No. 3006-93-7) (provided for in subheading 2925.19.91)

This HTS classification, 9902.04.60, pertains to specific chemical compounds classified under temporary legislation and special provisions, not for general commodity items. The described product, 1,1'-(1,3-Phenylene)bis(1H-pyrrole-2,5-dione) (CAS No. 3006-93-7), is designated for temporary tariff treatment and falls under Chapter 99, which encompasses various temporary modifications, trade agreement provisions, and agricultural adjustment measures. This specific entry is "provided for in subheading 2925.19.91," indicating it is a temporary or special provision for a chemical that would otherwise be classified under a more general heading in Chapter 29.

Given that Chapter 99 is dedicated to special and temporary measures, this classification is distinct from the broader commodity-based sibling categories such as live animals (Chapters 0101-0105) or other general merchandise found in earlier chapters. Its purpose is to manage specific import circumstances, often related to trade policy, agricultural support, or other legislative actions, rather than representing a standard product category.

As this is a leaf node, there are no further subcategories within 9902.04.60. The classification ends at this specific chemical compound and its associated temporary provision. Further classification would typically involve referencing the primary HTS heading (2925.19.91 in this case) for the underlying chemical substance and understanding the conditions or tariff rates associated with this specific Chapter 99 provision.
