HS Code 2902.90 – Cyclic hydrocarbons; n.e.c. in heading no. 2902

HS code 2902.90 is the 6-digit subheading for cyclic hydrocarbons, n.e.c. in heading no. 2902. It is used for cyclohexane, tetralin, decalin, dicyclopentadiene and indene.

What HS 2902.90 covers

This "not elsewhere specified" (n.e.c.) category for cyclic hydrocarbons covers a diverse range of aromatic and alicyclic compounds that do not fall under the more specific subheadings of HS 2902, such as benzene, toluene, xylenes, styrene, ethylbenzene, or cumene. This includes various specialized cyclic hydrocarbons used as solvents, chemical intermediates for niche applications, or components in fuel blends. Importers and exporters in this category often include specialty chemical manufacturers, research institutions, and companies dealing with custom synthesis. The trade volume for individual compounds within this code might be smaller than for major bulk aromatics, but collectively, they represent a significant segment of the fine and specialty chemical market. Key considerations for traders involve understanding the specific chemical identity and purity, regulatory compliance for novel or less common compounds, and specialized logistics. This code acts as a catch-all for important but less common cyclic hydrocarbons.

Codes often confused with 2902.90

Common mistake. This code is a common point of misclassification, as specific cyclic hydrocarbons might be incorrectly placed here instead of their more precise codes (e.g., 290211 for cyclohexane) or vice versa, requiring careful identification.

Top exporters and importers of HS code 290290, 2025

In 2025, the largest exporter of HS code 290290 in UN Comtrade data was China, with 31% of world exports; the largest importer in UN Comtrade data was India, with 12% 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).
