9902.05.71 - 1-[[1-ethyl-4-[3-(2-methoxyethoxy)-2-methyl-4-(methylsul- fonyl)benzoyl]-1H-pyrazol-5-yl]oxy]ethyl methyl carbonate (Tolpyralate) (CAS No. 1101132-67-5) (provided for in subheading 2933.19.23)

This HTS category, 9902.05.71, specifically covers Tolpyralate, a chemical compound identified by CAS No. 1101132-67-5. The description indicates it is a 1-[[1-ethyl-4-[3-(2-methoxyethoxy)-2-methyl-4-(methylsulfonyl)benzoyl]-1H-pyrazol-5-yl]oxy]ethyl methyl carbonate. While the HTS code resides within Chapter 99, its classification context directs users to its primary tariff provision under subheading 2933.19.23, which deals with heterocyclic compounds containing a pyrazole ring.

As a specific temporary provision, 9902.05.71 is distinct from other sibling categories within Chapter 99, which typically encompass various temporary tariff modifications, trade agreement measures, or agricultural import restrictions. Its sole purpose is to provide a specific classification for Tolpyralate, likely for administrative, statistical, or temporary trade policy reasons.

Since 9902.05.71 is a leaf node, there are no further subcategories. The classification is definitive for Tolpyralate as described. The inclusion of the parenthetical reference to subheading 2933.19.23 is crucial for understanding its fundamental tariff treatment for customs purposes beyond the temporary measure indicated by the 99xx code.
