Sourcing cyclopentene from China
Cyclopentene from China falls within a tariff line carrying 0% UK duty, with no anti-dumping or countervailing duty recorded. Suppliers must ensure chemicals are correctly labelled and packaged before placing them on the Great Britain market. Cambridge China Bridge sources cyclopentene.
Cyclopentene duty and tariff scope
Read from the UK Trade Tariff on 1 October 2026, heading 2902 covers cyclic hydrocarbons. Cyclopentene belongs within the other cyclanes, cyclenes and cycloterpenes line, 2902 19 00 00. The supplied tariff record shows 0% duty for goods from China, no anti-dumping or countervailing measures and no suspension.
The UK Trade Tariff attaches an export control for waste to this line. Waste shipment controls apply when the material being transported is waste. For recovered or discarded material from China, ask your customs broker to confirm the applicable requirements before shipment; the listed export measure alone does not establish the import procedure.
Confirm the commodity code against the actual composition and batch analysis, especially if the supplier offers a blend. For the wider cyclic-hydrocarbon heading, see our cyclohexane guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Cyclopentene, within other cyclanes, cyclenes and cycloterpenes | 2902 19 00 00 | 0% | None |
Specify cyclopentene identity and purity
Write cyclopentene explicitly in the purchase specification. Ask the factory to distinguish it from cyclopentane and cyclopentadiene. Agree the assay method, acceptable related impurities, water content and whether additives are present. Request a batch certificate of analysis and the supporting chromatogram.
Agree container material, closure, seal and sampling arrangements. Review the safety data sheet with your receiving site and carrier before ordering. Suppliers must ensure chemicals are correctly labelled and packaged before market placement. Confirm UK REACH registration responsibilities for your annual import volume with HSE, including whether an appointed only representative covers your imports.
Worked duty example
Illustrative example, not a quote: Illustrative order: 20 kg of cyclopentene in sealed chemical containers under 2902 19 00 00, invoiced at £3,000 free on board, with £980 of freight and insurance to the UK. The customs value is £3,980. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £3,980, so it is £796. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the purchase order, container labels and batch certificate to cyclopentene; investigate any different chemical name.
Assay: compare the batch chromatogram and independent sample results with the agreed purity and related-impurity specification.
Water and additives: check the agreed water result and any declared additives against the certificate and your intended process.
Containers: check seals, closures, leakage and batch markings on arrival; retain traceable samples using the agreed safe sampling procedure.

What goes wrong
Similar chemical names can lead to the wrong material being quoted or dispatched. An assay result alone may hide an unsuitable impurity profile, while a generic certificate may not describe the delivered batch. Treat inconsistent names, missing chromatograms and unexplained additives as reasons to hold acceptance.
Leaking closures or contaminated containers can invalidate an otherwise acceptable batch. Agree acceptance criteria and independent testing before loading, then compare arrival samples with retained dispatch samples. Use our quality inspection guide to organise the checks.

Frequently asked questions
What is the UK import duty on cyclopentene from China?
The supplied tariff record, read on 1 October 2026, shows 0% for 2902 19 00 00, with no anti-dumping or countervailing duty recorded.
Do I need UK REACH registration for cyclopentene?
Check your annual import total and ask HSE to confirm your UK REACH registration responsibilities, including whether an appointed only representative covers your imports.
What should a cyclopentene certificate of analysis show?
Ask for batch identity, assay method and result, related impurities, water and declared additives. Match it to the delivered containers and request the supporting chromatogram.
Can I accept cyclopentane instead of cyclopentene?
Do not accept it as a substitution against a cyclopentene order. Confirm the chemical identity and intended process suitability before approving any change.
