HS Code 2904.99 – Derivatives of hydrocarbons n.e.c. in heading no. 2904, whether or not halogenated

HS code 2904.99 is the 6-digit subheading for derivatives of hydrocarbons n.e.c. in heading no. 2904, whether or not halogenated. It is used for chlorinated paraffins, brominated flame retardants, nitrobenzene, toluene diisocyanate (TDI) precursors and sulfonated hydrocarbons.

What HS 2904.99 covers

This HS code encompasses a diverse range of organic chemical compounds derived from hydrocarbons, which have undergone further chemical modification but are not specifically classified elsewhere within heading 2904. These are often crucial intermediate chemicals used in the synthesis of pharmaceuticals, agrochemicals, dyes, and specialty polymers. Importers and exporters typically include large chemical manufacturers, pharmaceutical companies, and distributors specializing in industrial chemicals. Key aspects of trade involve stringent purity standards, adherence to regulatory compliance (especially for hazardous materials), and understanding their specific application in downstream industries. The global trade in these derivatives is driven by complex manufacturing supply chains, with significant volumes moving between major industrial hubs worldwide.

Codes often confused with 2904.99

Common mistake. Often confused with 2903 (Halogenated derivatives of hydrocarbons) or 290410 (Derivatives containing only sulfo groups), as the "n.e.c." (not elsewhere specified) nature can lead to ambiguity if the primary functional group isn't clearly defined.

Top exporters and importers of HS code 290499, 2025

In 2025, the largest exporter of HS code 290499 in UN Comtrade data was Kuwait, with 78% of world exports; the largest importer in UN Comtrade data was India, with 24% 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 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
