9902.07.20 - 1-(4-{4-[5-(2,6-Difluorophenyl)-4,5-dihydro-1,2-oxazol- 3-yl]-1,3-thiazol-2-yl}-1-piperidinyl)-2-[5-methyl-3- (trifluoromethyl)-1H-pyrazol-1-yl]ethanone (Oxathiapiprolin) (CAS No. 1003318-67-9) (provided for in subheading 2934.99.12)

This HTS category, 9902.07.20, specifically covers Oxathiapiprolin (CAS No. 1003318-67-9), a chemical compound identified as 1-(4-{4-[5-(2,6-Difluorophenyl)-4,5-dihydro-1,2-oxazol-3-yl]-1,3-thiazol-2-yl}-1-piperidinyl)-2-[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]ethanone. While the broader HTS structure organizes goods into chapters based on material or product type, this particular node falls under Chapter 99, which is designated for temporary legislation, trade agreement modifications, and specific import restrictions. Therefore, its primary purpose is not to classify a commodity by its inherent characteristics, but rather to implement specific customs provisions related to this named chemical.

Distinguishing this category from its numerous sibling categories within the HTS is crucial for accurate classification. The sibling categories, such as those starting with "0101" for live horses or "0102" for live bovine animals, are defined by the physical nature and biological type of the goods. In contrast, 9902.07.20 is a specialized classification within the temporary legislation chapter. It does not describe a general class of goods but rather a specific chemical compound subject to particular import regulations, often related to its intended use or unique regulatory status, as indicated by its provision under subheading 2934.99.12 for other heterocyclic compounds.

As a leaf node, this category has no further subcategories. This signifies that once goods meet the criteria for classification under 9902.07.20, they are at their most granular level of detail within this specific temporary provision. Classification here relies on confirming the identity of the imported substance as Oxathiapiprolin, as detailed in the HTS description, rather than navigating further subdivisions. This ensures that the specific trade or regulatory measures associated with this chemical are correctly applied.
