HS Code 2918.30 – Acids; carboxylic acids, (with aldehyde or ketone function but without other oxygen function), their anhydrides, halides, peroxides, peroxyacids and their derivatives

HS code 2918.30 is the 6-digit subheading for acids, carboxylic acids, (with aldehyde or ketone function but without other oxygen function), their anhydrides, halides, peroxides, peroxyacids and their derivatives. It is used for pyruvic acid, levulinic acid, acetoacetic acid, glyoxylic acid and oxaloacetic acid.

What HS 2918.30 covers

This HS code encompasses carboxylic acids that also possess an aldehyde or ketone functional group, along with their anhydrides, halides, peroxides, peroxyacids, and other derivatives. These compounds are crucial building blocks in organic synthesis, finding diverse applications in pharmaceuticals, flavors and fragrances, polymers, and specialty chemicals. International trade involves fine chemical manufacturers, pharmaceutical companies, and companies specializing in aroma chemicals. Key considerations for trade include the specific reactivity of the aldehyde or ketone group alongside the carboxylic acid, the high purity requirements for sensitive applications, and their role in creating complex molecules with desired properties for various industries, from food additives to drug synthesis.

Covers
  • Pyruvic acid
  • Levulinic acid
  • Acetoacetic acid
  • Glyoxylic acid
  • Oxaloacetic acid
  • Benzoylformic acid
  • Methyl acetoacetate
Examples
  • BASF (intermediates)
  • Merck (reagents)
  • Givaudan (flavor/fragrance precursors)

Codes often confused with 2918.30

Common mistake. Can be confused with simple aldehydes or ketones (e.g., 2912, 2914) if the carboxylic acid function is overlooked, or with other organic acids (e.g., 2918.19) if the aldehyde/ketone function is not identified.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
