Sourcing VAE emulsions from China

6% duty on copolymer emulsions

Read from the UK Trade Tariff on 1 October 2026, heading 3905 covers vinyl acetate and other vinyl polymers in primary forms. Vinyl acetate ethylene copolymer emulsions are aqueous dispersions under 3905 21 00 00. Goods from China carry 6%, with no listed anti-dumping or countervailing duty and no suspension. The table shows buying applications sharing this code, rather than separate tariff lines.

The tariff attaches import and export waste controls to this line. For waste imported into England under notification controls, the exporter must apply for consent to the competent authority in the dispatch country. For a proposed waste shipment from China, confirm the applicable requirements with your customs broker before shipping; also confirm controls before returning waste to China.

Confirm the commodity code using the composition, aqueous form and supplied product description. See the wider polymer guide for related materials. Use UK import duty and VAT when calculating landed cost.

Specify solids, film formation and preservation

State the intended adhesive, paper, textile or construction application. Agree solids content, viscosity and its test conditions, minimum film-forming temperature, glass transition temperature, particle size and whether the grade is plasticised. Trial the sample in your own formulation and agree acceptance limits before ordering.

Ask for residual vinyl acetate monomer information, the preservative identity, a safety data sheet and batch analysis. Confirm with HSE whether UK REACH registration applies to the polymer or its monomers, whether the preserved dispersion is a treated article, and what Great Britain conditions apply to its preservative active substances. Check applicable conditions before supply.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 tonnes of vinyl acetate ethylene copolymer emulsion in bulk containers under 3905 21 00 00, invoiced at £18,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £20,500. Duty at 6% is £1,230. Import VAT at 20% is charged on the customs value plus duty, £21,730, so it is £4,346. Import taxes total £5,576; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,230 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Analysis: compare arrival solids and viscosity with the agreed specification and batch certificate, using the same test conditions.

Film: draw down a sample and check for grit, skin, lumps or separation; compare film formation with the approved sample.

Packing: inspect container seals and leaks, match batch marks to documents, and check production date and remaining shelf life.

Chemical information: check preservative and residual monomer information against the agreed formulation. Everyone in the supply chain is responsible for correct chemical labelling and packaging before market placement.

What goes wrong

Freezing can coagulate the emulsion, older stock can thicken or develop microbial contamination, and low solids mean buying more water than intended. Grade drift can also change film formation and performance in your formulation. Agree protection from freezing and maximum stock age at loading.

Check solids and viscosity on arrival and hold suspect batches for assessment before production. Repeat the formulation trial when the grade or formulation changes. Set the sampling and release checks with the quality inspection guide.
