Sourcing chloroprene monomer from China

Chloroprene monomer: 4% duty

Read from the UK Trade Tariff on 1 October 2026, heading 2903 covers halogenated derivatives of hydrocarbons. For chloroprene monomer, check the residual unsaturated chlorinated derivatives line, 2903 29 00 90. The table shows specification and packaging options under that same line, rather than separate commodity codes.

The supplied tariff record gives 4% duty for goods from China and shows no anti-dumping or countervailing measure. Its suspension to 0.00 % applies only to trans-dichloroethylene, so it does not cover chloroprene. The line attaches dangerous-chemical export and waste-export controls. Ask your customs broker to confirm their relevance, including any return shipment; these are recorded as export controls.

Confirm the commodity code using the substance identity, composition and stabiliser details before declaring the goods. For wider heading context, see vinyl chloride monomer.

Specify the monomer and stabiliser

Write chloroprene monomer into the purchase specification and distinguish it from chloroprene rubber or formulated adhesive. Agree assay, impurity profile, water, acidity, stabiliser identity and content, analytical methods and batch acceptance criteria. Ask the producer to document storage conditions and the handling arrangements for transport and receipt.

HSE guidance requires UK REACH registration for a GB-based business importing a substance at or above 1 tonne per year. Resolve the registration position before ordering. Chemical classification is a supplier responsibility, and substances must be correctly labelled and packaged before being placed on the market. Hazardous chemicals supplied for workplace use require safety data sheets.

Worked duty example

Illustrative example, not a quote: Illustrative order: 15 tonnes of chloroprene monomer for a business process under 2903 29 00 90, invoiced at £21,000 free on board, with £3,500 of freight and insurance to the UK. The customs value is £24,500. Duty at 4% is £980. Import VAT at 20% is charged on the customs value plus duty, £25,480, so it is £5,096. Import taxes total £6,076; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £980 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match the purchase specification, batch analysis certificate, safety data sheet and package labels to chloroprene monomer.

Composition: compare assay, impurities, water, acidity and stabiliser results with the agreed limits; arrange independent testing where the batch evidence is incomplete.

Packaging: check closures, seals, leakage and package condition on arrival, and record the affected batch before accepting damaged goods.

Storage record: compare transport records and arrival conditions with the producer's documented handling instructions; arrange sampling through trained chemical handlers.

What goes wrong

A description such as chloroprene can lead to an offer for rubber or adhesive instead of monomer. A purity-only specification also leaves stabiliser content and impurities unresolved. Require the complete specification and batch analysis before shipment, then check the arriving batch against them.

Unexplained changes in appearance, missing storage records or leaking packages should trigger a hold and technical review. Do not release the batch into production on the strength of a generic certificate. Agree the evidence needed for acceptance or rejection before dispatch.
