2930.90.43.90 - Other

This HTS category, 2930.90.43.90, encompasses a residual group of organo-sulfur compounds that do not fall under the more specific subcategories within heading 2930.90.43. These are typically chemical substances where sulfur is directly bonded to carbon atoms, and they exhibit pesticidal properties or are intended for pesticidal use, but do not fit the precise definitions of the listed sibling categories. The scope is broad, covering various synthesized compounds that fulfill the general criteria of organo-sulfur pesticides but lack specific nomenclature or structural features that would place them elsewhere.

Distinguishing this category from its siblings is crucial for accurate classification. For instance, it does not include O-Ethyl-S-phenylethylphosphono-thiolothionate (fonofos), Phorate, Terbufos, or compounds specifically defined by the presence of a single methyl, ethyl, n-propyl, or isopropyl group attached to a phosphorus atom alongside other carbon atoms. Instead, 2930.90.43.90 is a fallback for other organo-sulfur pesticides that might possess different alkyl or aryl groups attached to sulfur and phosphorus, or have more complex structures not explicitly covered by the more narrowly defined sibling classifications.

As this is a terminal node within the HTS, there are no further subcategories to introduce. The classification concludes at this point, meaning any substance meeting the broad definition of an organo-sulfur pesticide not otherwise specified would be classified here. Therefore, the key to classifying goods under 2930.90.43.90 lies in a thorough review of the chemical structure and intended pesticidal application, ensuring it does not meet the specific criteria of any preceding, more granular HTS classifications.
