Sourcing Polyvinyl Fluoride Resin from China

0% duty on the dedicated resin line

Read from the UK Trade Tariff on 1 October 2026, heading 3904 covers polymers of vinyl chloride or other halogenated olefins in primary forms. Its dedicated polyvinyl fluoride line is 3904 69 10 00, limited to the forms specified in the chapter note. Only that product-specific line is shown here.

The supplied tariff record gives 0% duty for goods from China, with no anti-dumping or countervailing duty and no suspension listed for this line. It attaches import and export waste controls. For a China-to-England shipment subject to waste notification controls, the exporter must apply to the dispatch country's competent authority for consent. Confirm waste status and the applicable requirements with your customs broker before shipment.

Give your broker the polymer composition, additives, physical form and intended use to confirm the commodity code. For neighbouring resin families, see the wider PVC and PTFE resin guide.

Specify polymer identity and processing behaviour

Write out polyvinyl fluoride in the purchase specification. Distinguish it from polyvinylidene fluoride and polytetrafluoroethylene. Request the manufacturer's grade designation, composition, additive package and confirmation of whether the material is virgin or reprocessed.

Specify the supplied form, particle-size distribution, moisture, bulk density and contamination criteria. Agree the test methods and acceptance limits with your processor. For film or coating production, approve a sample through the intended process and assess film continuity, appearance and adhesion to the intended substrate.

Confirm with HSE the UK REACH registration requirements or exemptions applicable to the polymer, monomers and additives. Ask for the supplier's REACH position and a safety data sheet matching the supplied grade. Keep these with the technical data sheet and batch analysis certificate.

Worked duty example

Illustrative example, not a quote: Illustrative trial order: one tonne of polyvinyl fluoride resin powder under 3904 69 10 00, invoiced at £18,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £19,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £19,500, so it is £3,900. 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 bag labels, manufacturer, grade and batch numbers to the order and analysis certificate; independently confirm polymer identity when qualifying a supplier.

Powder condition: check particle size against the agreed method and inspect for caking, foreign particles and mixed material.

Process trial: compare the delivered batch with the approved sample for dispersion behaviour, film appearance and adhesion in your intended process.

Packaging: check seals, liners, moisture damage and legible batch labels; retain a sample from each delivered batch. Use the inspection guide to brief the inspector.

What goes wrong

A quotation for a different fluoropolymer can look similar until the material reaches your process. Vague grade descriptions, undisclosed additives and a certificate copied from another batch make acceptance difficult. Require the full polymer name and batch-specific results before releasing the shipment.

Caking, contamination or particle-size drift can change dispersion behaviour and leave defects in the resulting film or coating. Agree how suspect bags will be isolated and tested, and compare arrival samples with the approved material before production.
