2930.90.46.00 - dl-Hydroxy analogue of dl-methionine

This HTS classification, 2930.90.46.00, specifically covers the dl-Hydroxy analogue of dl-methionine. Methionine is an essential amino acid, and its hydroxy analogue is a synthetic compound often utilized as a nutritional supplement or as an intermediate in the production of other chemicals. Its inclusion under organo-sulfur compounds reflects the presence of sulfur within its molecular structure.

Within the broader category of organo-sulfur compounds, this particular code is situated under several "Other" subheadings, indicating it does not fit into more specific, pre-defined groups like thiols, sulfides, or disulfides. At this level, its closest sibling is 2930.90.49, which encompasses "Other" organo-sulfur compounds that are not specifically the dl-Hydroxy analogue of dl-methionine. Therefore, precise identification of the chemical structure is crucial for accurate classification, distinguishing this specific compound from other less defined organo-sulfur substances.

As this classification is a leaf node, there are no further subcategories. Classification decisions at this level will rely on confirming the exact chemical identity of the imported or exported merchandise. The defining characteristic for this code is the presence of the dl-Hydroxy analogue of dl-methionine, differentiating it from any other organo-sulfur compounds that might fall under the residual "Other" categories.
