HS Code for Butyric acid

Butyric acid, systematically referred to as butanoic acid, is a saturated acyclic monocarboxylic acid. Its classification under HS code 2915.60 is highly specific and accurate, as this subheading explicitly covers "butanoic acids, pentanoic acids, their salts and esters" within the broader category of "Saturated acyclic monocarboxylic acids and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives" (2915). The chemical structure of butyric acid, characterized by a four-carbon chain and a single carboxylic acid functional group, directly aligns with the "butanoic acids" mentioned in the description. This classification reflects its nature as a fundamental organic acid, widely utilized in various chemical syntheses, as a flavoring agent, and in the production of pharmaceuticals. Its inclusion in Chapter 29, dedicated to organic chemicals, is based on its defined molecular structure and industrial applications.

Products Included

• Butanoic acid
• Isobutyric acid (2-methylpropanoic acid)
• Salts of butanoic acid (e.g., sodium butyrate, calcium butyrate)
• Esters of butanoic acid (e.g., methyl butyrate, ethyl butyrate, butyl butyrate)
• Pentanoic acid (valeric acid) and its isomers
• Salts and esters of pentanoic acid

Common Misclassification

Misclassification of butyric acid can occur if the specific carbon chain length of the carboxylic acid is not precisely identified. HS 2915.29, which covers "Other acetic acid", is a common point of confusion, as acetic acid is a two-carbon carboxylic acid, distinct from the four-carbon butyric acid. Similarly, HS 2915.39, for "Other esters of acetic acid", would be incorrect for esters of butanoic acid. While both are esters of saturated acyclic monocarboxylic acids, the parent acid differs. Furthermore, HS 2915.90, a residual category for "Other saturated acyclic monocarboxylic acids", should not be used for butyric acid because "butanoic acids" are explicitly listed and covered by 2915.60. Accurate classification relies on matching the specific chemical name and structure to the detailed descriptions provided in the HS nomenclature.
