2915.90.50.10 - Acid chlorides

This classification, HTS Code 2915.90.50.10, specifically covers **acid chlorides** within the broader category of other saturated acyclic monocarboxylic acids and their derivatives. Acid chlorides are reactive organic compounds characterized by the presence of a -COCl functional group. They are often used as intermediates in the synthesis of esters, amides, and other organic compounds. This entry encompasses acid chlorides that do not fall under more specific subheadings within Chapter 29.

Within the "Other" category at this level, HTS 2915.90.50.10 is distinguished from its sibling, 2915.90.50.50 ("Other"). While both are residual classifications for unlisted derivatives, 2915.90.50.10 is exclusively for acid chlorides, whereas 2915.90.50.50 would cover any other derivatives of saturated acyclic monocarboxylic acids not otherwise specified, such as peroxides, peroxyacids, or complex halogenated derivatives not fitting into prior subheadings. Therefore, the key differentiator is the presence of the acid chloride functional group.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Classification under this heading requires careful examination to confirm the presence of the acid chloride functional group and to ensure that the specific chemical does not meet the criteria for any preceding, more specific subheadings within the 2915 chapter. Examples of goods classified here might include acetyl chloride, propionyl chloride, or benzoyl chloride when imported as distinct chemical entities.
