2915.70.01.50 - Other

This HTS category, "Other," within the classification of Palmitic acid, stearic acid, their salts and esters, encompasses a range of products that are chemically derived from these fatty acids but do not fall under the specific classifications for palmitic acid or stearic acid themselves. This includes various esters and salts of palmitic acid and stearic acid, as well as their anhydrides, halides, peroxides, peroxyacids, and their halogenated, sulfonated, nitrated, or nitrosated derivatives, provided they are not specifically enumerated elsewhere. The focus is on compounds that share the fundamental structure of these saturated acyclic monocarboxylic acids but have undergone further chemical modification or are presented in a derivative form.

This classification is distinct from its siblings, 2915.70.01.10 (Palmitic acid) and 2915.70.01.20 (Stearic acid), which exclusively cover the pure acids. While palmitic and stearic acids are the foundational components, this "Other" category accounts for the diverse range of chemical compounds that are synthesized from them. It is crucial for customs purposes to differentiate between the raw fatty acids and their various ester, salt, or other chemically modified forms, as these derivatives may have different applications, properties, and tariff treatments.

As this is a terminal node within the HTS, there are no further subcategories to introduce. Therefore, classification within this heading relies on the accurate determination that a product is indeed a derivative of palmitic or stearic acid, is not a pure palmitic or stearic acid, and does not fit into any other more specific HTS classification. Examples of goods that might fall here include methyl palmitate, ethyl stearate, glycerol monostearate, or the sodium salts of these fatty acids, when not specifically listed under other HTS headings.
