Hexafluoropropylene duty and classification

Read from the UK Trade Tariff on 1 October 2026, heading 2903 covers halogenated derivatives of hydrocarbons. Hexafluoropropylene falls within the description of other unsaturated fluorinated derivatives under 2903 59 00 90, subject to confirmation of the actual product. The supplied file contains only this relevant line, so the table does not add unrelated chemicals.

The line carries 4% duty for goods from China, with no anti-dumping or countervailing duty recorded. Its 0.00 % autonomous suspension names other substances and does not cover hexafluoropropylene. The UK Trade Tariff attaches an export control for waste; ask your customs broker to confirm its relevance to the transaction, especially if material is being returned or discarded.

Confirm the substance identity, purity and any added components before choosing the commodity code. For the wider heading, see the vinyl chloride monomer guide. Use the import duty and VAT guide to assess landed cost.

Specify the gas and its delivery system

Write hexafluoropropylene explicitly on the purchase specification. Agree the intended process, assay method, impurity profile, moisture limit and acceptance criteria with the factory and your technical team. Ask for actual batch results rather than a generic product brochure.

Agree cylinder material, valve connection, protective fittings, net contents and the arrangements for empty cylinders. Have the receiving site confirm compatibility with its gas handling equipment before dispatch.

UK REACH requires businesses to identify and manage the risks of substances they place on the Great Britain market. Before importing, ask HSE to confirm your registration position for the substance and planned annual volume. Everyone in the supply chain is responsible for correct labelling and packaging before placing substances on the market.

Worked duty example

Illustrative example, not a quote: Illustrative shipment of hexafluoropropylene in cylinders under 2903 59 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, invoice, cylinder labels and safety data sheet to hexafluoropropylene. Resolve any description referring to hexafluoropropane before accepting the shipment.

Batch quality: match the certificate of analysis to the delivered batch and compare assay, moisture and individual impurities with the agreed acceptance criteria. Arrange independent testing where needed.

Cylinders: check identification, valve connection, protective fittings, seals and visible damage against the approved packing specification. Have trained personnel investigate suspected leakage.

Receiving documents: reconcile cylinder identifiers and net contents with the packing list. Check that the receiving team has the safety data sheet and the agreed handling instructions.

What goes wrong

A similar chemical name can lead to the wrong substance being quoted, labelled or declared. A headline purity result can also conceal an impurity that matters to your process. Make identity and the individual impurity limits part of the written acceptance specification.

An incompatible valve can prevent connection to the receiving equipment, while a generic analysis certificate leaves the delivered batch unverified. Keep disputed cylinders separate pending assessment and retain photographs, labels and batch documents. Use factory verification to check who actually manufactures and fills the gas.

Cambridge China Bridge sources these products for UK businesses, checking the factory and the documents before shipment. See factory verification. For repeat volumes, see container programmes.

Frequently asked questions

What is the UK import duty on hexafluoropropylene from China?

The relevant line, 2903 59 00 90, carries 4% duty. Its named suspension does not cover hexafluoropropylene, and the supplied tariff data records no anti-dumping or countervailing duty.

Does hexafluoropropylene qualify for the tariff suspension?

The suspension on this line names other substances. Do not claim it for hexafluoropropylene merely because the commodity code is shared.

What should I ask the Chinese factory to test?

Ask for batch-specific assay, moisture and individual impurity results using agreed methods. Set acceptance criteria around your intended process rather than accepting a headline purity alone.

What must I check before selling the gas in Great Britain?

Confirm your UK REACH position, manage the chemical risks and ensure correct labelling and packaging. Match the safety data sheet and batch evidence to the actual substance supplied.
