HS code · 6-digit subheading
HS Code 2916.19 – Acids; unsaturated acyclic monocarboxylic, cyclic monocarboxylic, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives, n.e.c. in item no. 2916.1
HS code 2916.19 is the 6-digit subheading for acids, unsaturated acyclic monocarboxylic, cyclic monocarboxylic, their anhydrides, halides, peroxides and peroxyacids, their halogenated, sulphonated, nitrated or nitrosated derivatives, n.e.c. in item no. 2916.1. It is used for sorbic acid, crotonic acid, fumaric acid, maleic anhydride and cinnamic acid.
What HS 2916.19 covers
This "not elsewhere specified" (NES) code within the 2916.1 subheading covers a diverse range of unsaturated acyclic and cyclic monocarboxylic acids, their anhydrides, halides, peroxides, peroxyacids, and their halogenated, sulphonated, nitrated, or nitrosated derivatives, provided they are not specifically classified under 2916.11 through 2916.16. This category serves as a catch-all for specialty chemicals used in niche applications across various industries, including pharmaceuticals, agrochemicals, polymers, and fine chemicals. Importers are typically specialized chemical distributors, research and development firms, or manufacturers requiring specific intermediates. Exporters are often specialty chemical producers in technologically advanced economies. Trade in these compounds is characterized by lower volumes but higher value, with a strong emphasis on purity, custom synthesis, and intellectual property.

Codes often confused with 2916.19
Common mistake. This code is a residual category, so misclassification often occurs with more specific codes within 2916.1 (if a specific acid or derivative is listed there) or with other organic chemical codes in Chapter 29 if the compound has other functional groups. It's crucial to ensure the chemical doesn't fit a more specific heading.
Top exporters and importers of HS code 291619, 2025
In 2025, the largest exporter of HS code 291619 in UN Comtrade data was China, with 38% of world exports; the largest importer in UN Comtrade data was the United States, with 13% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
