HS 290211 Cyclanes, cyclenes and cycloterpenes

Quick Answer: HS Code 2902.11 covers unsaturated cyclic hydrocarbons, specifically cyclanes, cyclenes, and cycloterpenes. These are organic chemical compounds characterized by their ring structures, often used as intermediates in chemical synthesis, solvents, or in the production of polymers and pharmaceuticals. For instance, common examples include cyclohexane and cyclohexene. Importers and exporters should note the varying duty rates across major jurisdictions. The UK and EU apply a 0.00% ad valorem duty rate, indicating duty-free entry for these products. In contrast, the US imposes a more complex duty structure, with a "Free" rate for some entries, but also a specific rate of 15.4¢/kg plus an ad valorem rate of 40% for others, depending on specific product characteristics or country of origin. This significant difference necessitates careful classification and origin determination to avoid unexpected costs.

How to Classify This HS Code?

What products does HS 290211 cover?

This subheading covers cyclohexane, a saturated alicyclic hydrocarbon with the chemical formula C6H12. As defined by the World Customs Organization (WCO) Harmonized System Nomenclature and reflected in the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC, HS 2902.11 specifically identifies cyclohexane within the broader category of cyclanes, cyclenes, and cycloterpenes of Heading 2902. It is a colorless, flammable liquid primarily used as a solvent for cellulose ethers, fats, oils, waxes, resins, and as a raw material in the production of nylon intermediates like adipic acid and caprolactam, making its precise classification critical for trade.

What falls outside HS 290211?

The following products are excluded from HS 290211: other cyclanes, cyclenes, and cycloterpenes, which are classified in other subheadings under Heading 2902, such as methylcyclohexane (2902.19). Aromatic hydrocarbons, even if they contain a cyclohexane ring fused with an aromatic ring (e.g., tetralin or decalin), are generally classified under Heading 2902 as cyclic hydrocarbons but not specifically under 2902.11. Furthermore, derivatives of cyclohexane, such as cyclohexanol (2906.12) or cyclohexanone (2914.22), are excluded because they contain oxygen-functional groups, moving them to different chapters or headings based on their specific chemical structure and functional groups, as per Chapter 29's structural hierarchy.

What are common classification mistakes for HS 290211?

A common error is misclassifying other cyclanes or even certain aromatic hydrocarbons as cyclohexane under HS 290211. For instance, methylcyclohexane, while structurally similar, is correctly classified under HS 2902.19. Another frequent mistake involves classifying cyclohexane derivatives, such as cyclohexanol, under this subheading; however, these are correctly classified under other headings in Chapter 29 based on their specific functional groups, following the principles of General Interpretative Rule (GRI) 1 and the Chapter 29 Notes. Importers sometimes overlook the precise chemical definition of "cyclohexane" and apply the code too broadly to any cyclic hydrocarbon, leading to incorrect duty rates and potential compliance issues.

How should importers classify products under HS 290211?

The correct procedure for classifying products under HS 290211 requires meticulous attention to the chemical identity of the substance. Importers and customs brokers must first confirm that the product is indeed pure cyclohexane (C6H12) and not a derivative or another cyclane. This typically involves reviewing the Certificate of Analysis (CoA) or Safety Data Sheet (SDS) provided by the manufacturer, which specifies the chemical name, CAS number (e.g., 110-82-7 for cyclohexane), and purity. Subsequently, cross-referencing these details with the WCO Explanatory Notes for Heading 2902 and the specific subheading 2902.11 in the USITC HTSUS or EU TARIC is essential to ensure accurate classification and compliance with international trade regulations.

FAQ

What are the typical Most Favored Nation (MFN) duty rates for products classified under HS 2902.11, 'Cyclohexane'?

For products classified under HS 2902.11 (Cyclohexane), the MFN duty rates can vary significantly by importing country. For example, the United States generally applies a 'Free' duty rate for MFN imports under HTSUS 2902.11.00. The European Union's TARIC database also indicates a 0.00% ad valorem duty rate for MFN imports of cyclohexane. However, other countries may apply different rates, such as a 3.5% ad valorem rate or even compound duties in specific circumstances. Importers should always verify the exact duty rate applicable to their specific destination country using the official national tariff schedule (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff).

What are the key classification criteria for distinguishing cyclohexane under HS 2902.11 from other cyclanes or related hydrocarbons?

The primary classification criterion for HS 2902.11 is the chemical identity of 'Cyclohexane' itself. This heading specifically covers cyclohexane, a saturated alicyclic hydrocarbon with the chemical formula C6H12. It is distinguished from other cyclanes (like methylcyclohexane, which falls under 2902.19) by its precise molecular structure and chemical name. The Harmonized System Explanatory Notes for Chapter 29 provide guidance on the chemical purity and isomer considerations. Importers and customs brokers must ensure that the product's chemical name, CAS number, and purity align precisely with the definition of cyclohexane to avoid misclassification.

Are there any preferential duty rates available for cyclohexane (HS 2902.11) under common free trade agreements?

Yes, preferential duty rates are often available for cyclohexane (HS 2902.11) under various free trade agreements (FTAs) and Generalized System of Preferences (GSP) schemes, provided the product meets the respective rules of origin. For instance, under agreements like USMCA (United States-Mexico-Canada Agreement), EU-Japan EPA, or the UK's trade agreements, cyclohexane originating from a partner country may enter at a 0.00% preferential duty rate. Importers must ensure they have valid documentation, such as a certificate of origin or origin declaration, to claim these preferential rates. Failure to provide proper documentation will result in the application of the MFN duty rate.

What specific documentation is required for importing cyclohexane (HS 2902.11) to ensure smooth customs clearance?

For importing cyclohexane (HS 2902.11), standard customs documentation is required, including a commercial invoice, packing list, bill of lading or air waybill, and a certificate of origin (if claiming preferential duty rates). Due to its chemical nature, a Safety Data Sheet (SDS) is highly recommended and often required by regulatory bodies for hazardous materials, even if not strictly a customs document. Depending on the destination country, additional chemical import permits or declarations to environmental or chemical control agencies may be necessary. For example, in some jurisdictions, compliance with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations in the EU or TSCA (Toxic Substances Control Act) in the US might necessitate specific declarations or registrations.
