9902.05.61 - tert-Butyl (E)-α-(1,3-dimethyl-5-phenoxypyrazol-4-ylmethyleneamino oxy)-p-toluate (Fenpyroximate (ISO)) (CAS No. 134098-61-6) (provided for in subheading 2933.19.23)

This HTS category, 9902.05.61, specifically covers tert-Butyl (E)-α-(1,3-dimethyl-5-phenoxypyrazol-4-ylmethyleneamino oxy)-p-toluate, also known by its ISO name, Fenpyroximate. This compound, identified by CAS No. 134098-61-6, is a chemical substance primarily used as an acaricide and insecticide. Its classification within Chapter 99 indicates it falls under special provisions related to temporary legislation or modifications.

Distinguishing this category from its sibling categories is crucial for accurate classification. Unlike the broad categories in Chapter 01, which cover live animals, or other chapters dealing with raw materials or finished goods, 9902.05.61 is highly specific. It is reserved for this particular chemical compound and its direct commercial forms, not for general agricultural chemicals or pesticides which would be classified under their respective chemical chapters, such as Chapter 29. The parenthetical note "(provided for in subheading 2933.19.23)" explicitly points to its underlying chemical classification, but this 9902 entry signifies a special trade or regulatory treatment.

As this node is a leaf node, there are no further subcategories to introduce. Classification decisions within this specific HTS code will therefore focus on confirming the identity of the imported merchandise as Fenpyroximate and ensuring compliance with any temporary provisions or restrictions associated with its entry under Chapter 99. The precise chemical nomenclature and CAS number are the primary identifiers for this classification.
