HS code · 6-digit subheading

HS Code 2932.99 – Heterocyclic compounds; with oxygen hetero-atom(s) only, no lactones or unfused furan rings in the structure, other than isosafrole, 1-(1,3-benzodiaxol-5-yl) propan-2-one, piperonal, safrole, tetrahydrocannabinols (all isomers), carbofuran (ISO)

HS code 2932.99 is the 6-digit subheading for heterocyclic compounds, with oxygen hetero-atom(s) only, no lactones or unfused furan rings in the structure, other than isosafrole, 1-(1,3-benzodiaxol-5-yl) propan-2-one, piperonal, safrole, tetrahydrocannabinols (all isomers), carbofuran (ISO). It is used for specific pharmaceutical intermediates, specialty polymer additives, advanced organic synthesis reagents, certain food-grade antioxidants and specific flavor/fragrance molecules.

What HS 2932.99 covers

This 'other' category encompasses a diverse range of heterocyclic compounds containing only oxygen hetero-atoms, excluding lactones, unfused furan rings, and specific controlled substances like THC, carbofuran, and certain drug precursors. It serves as a catch-all for numerous complex organic chemicals vital across various industries. These compounds function as intermediates in pharmaceutical synthesis, components in agrochemicals, specialty chemicals for polymers, and ingredients in flavors and fragrances. Importers and exporters include a broad spectrum of entities, from large chemical manufacturers and pharmaceutical giants to specialized fine chemical producers and research laboratories. Trade involves both bulk raw materials and highly purified intermediates, reflecting the wide applications of these versatile chemical building blocks.

Codes often confused with 2932.99

Common mistake. Often confused with other oxygen heterocyclics like lactones (293220) or furan derivatives (29321X), or even other 'other' categories like 293290, due to the broad nature of the chemical group and its exclusions.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
