HS Code 29.02 – Cyclic hydrocarbons

HS code 2902 is a 4-digit heading in the Harmonized System that covers: Cyclic hydrocarbons. Heading 2902 covers cyclic hydrocarbons, a class of organic compounds characterized by carbon atoms forming closed rings, with or without side chains. This includes both aromatic hydrocarbons, such as benzene, toluene, and xylenes (BTX), known for their distinct ring structures and stability, and alicyclic hydrocarbons, which are saturated or unsaturated non-aromatic cyclic compounds like cyclohexane. These compounds are indispensable as starting materials in the production of polymers, synthetic fibers, pharmaceuticals, dyes, and various industrial solvents. The scope generally encompasses pure, individual cyclic hydrocarbons. Mixtures of specific isomers (e.g., mixed xylenes) are also included, provided they are not crude mixtures primarily for fuel (which would fall under Chapter 27). Proper classification under 2902 is vital for trade compliance due to varying tariffs, safety regulations, and environmental controls associated with specific cyclic hydrocarbons, some of which are regulated due to toxicity or ozone depletion potential. Historically, the development of the petrochemical industry has been closely linked to the efficient production and trade of these cyclic compounds. This heading builds upon the foundational hydrocarbon structures of Chapter 29, providing more complex, ring-based organic building blocks.

Benzene, Toluene, o-Xylene, m-Xylene, p-Xylene, Mixed Xylenes, Ethylbenzene, Styrene, Cumene, Cyclohexane, Decahydronaphthalene, Tetrahydronaphthalene, Indane, Limonene, Pinene, Turpentine (pure chemical components), Naphthalene (pure), Biphenyl, Methylcyclohexane, Isopropylbenzene, Vinylcyclohexene, Dicyclopentadiene (pure).

A common mistake when classifying under 2902 is confusing pure cyclic hydrocarbons with crude aromatic mixtures or coal tar distillates. Heading 2707 (Oils and other products of the distillation of high temperature coal tar; similar products in which the weight of the aromatic constituents exceeds that of the non-aromatic constituents) specifically covers these less refined mixtures, which are often used as fuels or blending components rather than pure chemical feedstocks. Another error is misclassifying certain terpene compounds, which are often naturally derived and can sometimes be found in essential oils (Chapter 33) if not isolated as pure chemicals. Lastly, very complex, formulated chemical preparations containing cyclic hydrocarbons might belong to 3824 (Prepared chemical products not elsewhere specified or included).

In 2025, the top exporters of HS code 2902 in UN Comtrade data were South Korea ($7.3B, 22% of world exports), Japan ($3.0B) and the United States ($2.7B). World exports came to about $32.6B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 2902 in UN Comtrade data were China ($13.4B, 38% of world imports), India ($3.0B) and the United States ($1.7B). World imports came to about $35.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 2902 is a 4-digit heading under Chapter 29 of the Harmonized System. The first 2 digits (29) identify the chapter, and digits 3-4 (02) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
