HS Code for Cyclohexane

Cyclohexane is classified under HS code 2902.11 because it is a cyclic hydrocarbon belonging to the cyclanic series. According to the Harmonized System's Chapter 29, which governs organic chemicals, products must generally be separate chemically defined compounds to be classified here. Cyclohexane (C6H12) fits this criterion perfectly. Heading 2902 specifically addresses hydrocarbons, and the subheadings are organized by the molecular structure. Since cyclohexane is a saturated alicyclic hydrocarbon, it falls under the category of cyclanes. Subheading 2902.11 is a specific provision for this compound, reflecting its significant industrial importance as a precursor in the production of nylon and as a non-polar solvent. The classification remains consistent regardless of whether the product is used as a laboratory reagent or a bulk industrial feedstock, provided it meets the purity standards set forth in the Chapter 29 notes, which typically require the substance to be at least 95% pure by weight. If the product contains significant additives or is part of a mixture, the classification may shift to Chapter 27 or 38.

Products Included

• Pure cyclohexane (95% or more purity)
• Technical grade cyclohexane
• Cyclohexane used as a laboratory reagent
• Cyclohexane feedstock for adipic acid production

Common Misclassification

Cyclohexane is frequently confused with benzene, which is classified under HS code 2902.20. While both are six-carbon rings, benzene is an aromatic hydrocarbon, whereas cyclohexane is a saturated cyclane. Another common error involves petroleum fractions containing cyclohexane; if the product is not a separate chemically defined compound but rather a mixture of hydrocarbons obtained by the distillation of petroleum, it must be classified under heading 2710. Furthermore, other cyclanes like cyclopropane or cyclobutane fall under 2902.19, so precise identification of the ring structure is required.

FAQ

What is the HS code for Cyclohexane?

The specific HS code for cyclohexane is 2902.11, which falls under the broader category of cyclic hydrocarbons.

Does the purity of cyclohexane affect its HS code?

Yes, for classification in Chapter 29, the product must generally be a separate chemically defined compound. If it is a crude petroleum distillate containing cyclohexane, it belongs in Chapter 27.
