HS Code for Formic acid

Formic acid, also known as methanoic acid, is classified under HS code 2915.11. As the simplest saturated acyclic monocarboxylic acid, it is the lead compound in Heading 2915. The classification is determined by Chapter 29 of the Harmonized System, which covers organic chemicals. Formic acid is classified here whether it is in anhydrous form or in aqueous solutions of various concentrations, provided it remains a separate chemically defined compound. The HS nomenclature prioritizes the chemical structure of the molecule, and since formic acid contains only one carbon atom and a single carboxyl group, it fits the definition of a saturated acyclic monocarboxylic acid perfectly. It is an essential industrial chemical used in the production of leather, textiles, and as a preservative in animal feed (silage).

Products Included

• Anhydrous formic acid
• Aqueous solutions of formic acid (e.g., 85% or 94% concentration)
• Technical grade formic acid
• Pharmaceutical grade formic acid

Common Misclassification

Formic acid is often confused with its derivatives, such as formate salts (2915.12) or formate esters (2915.13). It is also sometimes misclassified under HS code 3808.94 (disinfectants) when it is sold specifically for its antimicrobial properties in retail packaging. However, for industrial bulk shipments, 2915.11 is the correct code regardless of the intended use, as per the hierarchy of the Harmonized System which favors specific chemical headings over general use headings.

FAQ

What is the HS code for formic acid 85%?

The HS code for formic acid at 85% concentration is 2915.11.

Is formic acid classified as a hazardous material for shipping?

While HS codes are for tariff classification, formic acid is indeed a corrosive substance (UN 1779) and requires specific dangerous goods documentation in addition to its HS code.
