2915.13.50.00 - Other

This HTS category, "Other," specifically encompasses esters of formic acid that are not classified under the sibling category of "Aromatic." These substances are organic compounds formed by the reaction of formic acid with an alcohol, excluding those where the alcohol portion is derived from an aromatic compound. Examples include simple alkyl formates such as methyl formate, ethyl formate, and propyl formate. These esters are characterized by their distinctive odors and are utilized in a variety of industrial applications, including as solvents, flavorings, and in the production of other chemicals.

The key distinguishing factor for this category lies in the structure of the alcohol moiety. While all are esters of formic acid, those classified under "Aromatic" would involve an alcohol derived from an aromatic hydrocarbon (e.g., phenyl formate). This residual category, therefore, captures all other formic acid esters that do not possess this aromatic characteristic, focusing on aliphatic (straight or branched chain) or cycloaliphatic alcohol derivatives.

As this is a leaf node, there are no further subcategories within this specific HTS code. Therefore, the classification of an ester of formic acid into 2915.13.50.00 hinges solely on its non-aromatic nature. Importers and exporters should carefully examine the chemical structure of the ester in question to ensure it meets this criterion, distinguishing it from any potentially aromatic counterparts at the same hierarchical level.
