2930.90.92 - Other

This HTS category, HTS Code 2930.90.92, encompasses "Other" organo-sulfur compounds that do not fall into more specific subheadings within the broader organo-sulfur compound classification. It serves as a residual category for a diverse range of sulfur-containing organic chemicals whose unique chemical structures or specific applications prevent their classification elsewhere. The scope is broad, including compounds where sulfur is directly bonded to carbon, or where sulfur is part of a functional group within a larger organic molecule, but not fitting into more precisely defined chemical families.

Distinguishing this category from its sibling, 2930.90.71.00 (Dibutylthiourea), is crucial. While both fall under the general umbrella of organo-sulfur compounds, 2930.90.71.00 specifically designates dibutylthiourea. HTS Code 2930.90.92, conversely, is for all other organo-sulfur compounds that are not dibutylthiourea, nor are they captured by any other specific enumeration within the organo-sulfur provisions. This means that any organo-sulfur compound that does not have a more precise classification is likely to be found here.

Within HTS Code 2930.90.92, further subdivisions exist to classify more specific types of "Other" organo-sulfur compounds. These subcategories, such as O,O-Diethyl S-[2-(diethylamino)- ethyl] phosphorothioate and its salts, Thiodiglycol, Cysteine hydrochloride, and various aminoethane thiols, are provided to offer greater granularity. These subdivisions are based on the presence of specific functional groups, the type of organic radical attached to sulfur, or the presence of additional elements like phosphorus, allowing for more accurate and consistent classification of a wider array of chemical substances.
