Sourcing PVA resin powder from China

Resin powder: 6% standard duty, suspended to 0%

Read from the UK Trade Tariff on 1 October 2026, heading 3905 covers vinyl polymers in primary forms. Polyvinyl alcohol includes material containing unhydrolysed acetate groups. The powder lines carry 6% standard duty from China and a suspension to 0%, with no listed anti-dumping or countervailing duty. The suspension excludes mixtures, preparations and products made up of different components containing the listed products.

The tariff attaches waste import and export controls. Waste shipment controls apply only to waste. For imports into England under notification controls, the exporter in China must apply to its competent authority for consent. Confirm the applicable route with your customs broker before buying recovered or discarded material. Line 3905 30 00 92 also attaches authorised-use provisions: ask your broker to confirm the declaration requirement rather than assuming the suspension removes it.

The table includes the wafer-coating preparation only to distinguish it from powder. Confirm your commodity code using composition, viscosity, hydrolysis and intended use. The listed homopolymer definition uses viscosity measured in 4% aqueous solution at 20 °C and hydrolysis measured according to ISO 15023-2. See the wider heading guide and import duty and VAT guide.

Specify hydrolysis, viscosity and dissolution

Specify polyvinyl alcohol resin powder explicitly, rather than accepting a supplier's abbreviated grade name. Record degree of hydrolysis, viscosity and its test conditions, particle size, moisture or volatile matter, ash and intended application. Request a batch certificate of analysis and agree the dissolution method used for sample approval.

Trial the powder in your own adhesive, coating, sizing or mortar process. Record water temperature, mixing sequence and whether undissolved particles or gels remain. Keep an approved sample for comparison with production batches.

Confirm with HSE whether UK REACH registration or any exemption applies to the polymer and its monomers. Check the importer's position for the actual composition. Great Britain retains chemical classification, labelling and packaging duties; review the supplier's safety data sheet and proposed bag label before supply.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 tonnes of bagged polyvinyl alcohol resin powder under 3905 30 00 95, 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 6% is £1,170. Import VAT at 20% is charged on the customs value plus duty, £20,670, so it is £4,134. Import taxes total £5,304; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,170 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match the bag grade, batch number and certificate to the purchase specification.

Analysis: sample across bags and compare viscosity, hydrolysis, volatile matter and ash with the agreed results.

Dissolution: repeat the approved preparation method and check for grit, persistent lumps or gel.

Packing: check bag seals, liners, moisture damage and batch traceability. Agree sampling and release checks through the quality inspection guide.

What goes wrong

A similar grade name can conceal different hydrolysis or viscosity. The powder may then dissolve differently or gel in the buyer's process. Moisture ingress can leave caked bags, while inconsistent particle size can change handling and dissolution. Hold affected batches for testing against the approved sample.

A blended adhesive powder can be mistaken for unmodified resin, leading to an unsupported suspension claim. Obtain the full composition before costing duty. A certificate alone does not demonstrate performance in your process: approve a production sample and repeat the agreed checks on arrival.
