9902.04.75 - (R)-α-Cyano-3-phenoxybenzyl (1S,3S)-3-(2,2-dichlorovinyl)-2,2 dimethylcyclopropanecarboxylate and (S)-α-cyano-3-phenoxybenzyl (1R)-cis-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecar- boxylate isomers (α-cypermethrin technical) (CAS No. 67375-30-8) (provided for in subheading 2926.90.30)

This HTS category, 9902.04.75, specifically covers technical-grade α-cypermethrin, a synthetic pyrethroid insecticide. This classification applies to the combined isomers ((R)-α-Cyano-3-phenoxybenzyl (1S,3S)-3-(2,2-dichlorovinyl)-2,2 dimethylcyclopropanecarboxylate and (S)-α-cyano-3-phenoxybenzyl (1R)-cis-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate) of this chemical compound, identified by CAS Number 67375-30-8. Its primary function is as an active ingredient in the production of various pest control products.

Distinguishing this category from its siblings within the broader HTS structure is crucial. Unlike Chapter 01 headings that deal with live animals, or other chapters that classify raw materials or finished goods by their physical composition or end-use, 9902.04.75 falls under Section XXII, denoting special classification provisions. This particular heading is part of temporary legislation or modifications, indicating its classification is subject to specific trade agreements or statutory requirements rather than permanent tariff schedules. While its chemical components might be classifiable under other headings, such as subheading 2926.90.30 for organic compounds containing cyano groups, this specific 9902 code signifies a distinct regulatory treatment.

As a leaf node, HTS code 9902.04.75 does not have further subcategories. Therefore, classification under this code is definitive for the described isomers of technical α-cypermethrin when imported under the specific conditions outlined by the temporary legislation or trade agreements associated with Chapter 99. Importers must carefully verify that their product precisely matches the chemical description and is intended for import under the circumstances prompting this special classification.
