2933.99.01.00 - Butyl (R)-2-[4-(5-trifluoromethyl-2- pyridinyloxy)phenoxy]propanoate 🖩

This HTS classification covers specific heterocyclic compounds containing nitrogen atoms within their ring structures. Notably, the nomenclature "Other" at this level indicates that these compounds are not specifically enumerated in preceding subheadings under 2933.99. The primary characteristic defining this group is the presence of at least one nitrogen atom within a ring system, coupled with the absence of other hetero-atoms like oxygen or sulfur in the heterocyclic ring itself.

Distinguishing this specific subheading from its siblings requires careful attention to the precise chemical structure and naming conventions. For instance, while 2933.99.02.00 deals with quinoxaline derivatives, and 2933.99.06.00 enumerates specific triazole-based fungicides like Myclobutanil and Fenbuconazole, this subheading encompasses other distinct heterocyclic compounds that do not fall into those specifically named categories. The presence of an ester functional group and the specific arrangement of trifluoromethyl and pyridinyloxy moieties on a phenoxypropanoate backbone are key identifiers for this particular classification.

As this is a leaf node within the HTS, there are no further subdivisions. Therefore, classification within 2933.99.01.00 relies on a precise match of the chemical name and structure to the goods being imported or exported. The inclusion of Butyl (R)-2-[4-(5-trifluoromethyl-2- pyridinyloxy)phenoxy]propanoate exemplifies the type of chemical entity intended for this specific classification. Importers and exporters should verify that the chemical composition and structural features align precisely with this description to ensure accurate customs declaration.
