Sourcing polyethyl methacrylate resin from China

Normally 6% duty on the residual acrylic line

Read from the UK Trade Tariff on 1 October 2026, heading 3906 covers acrylic polymers in primary forms. For polyethyl methacrylate resin, check the residual line 3906 90 90 90 against the actual composition. The table shows purchasing forms sharing this code, rather than separate tariff subheadings. See the wider acrylic polymers guide.

The residual line carries 6% duty for goods from China, with no anti-dumping or countervailing measure recorded. A 0% suspension is attached for specified products, but the supplied transparent-polymer description is incomplete. Do not assume ordinary polyethyl methacrylate resin qualifies. Ask your broker to check the complete suspension conditions and confirm the commodity code.

The tariff also attaches waste import and export controls. Confirm their application to the shipment with your customs broker. If material from China is imported into England under waste notification controls, the exporter must apply to the dispatch country's competent authority for consent. Have the broker confirm the remaining requirements before shipment.

Specify the resin identity and solution behaviour

Write out polyethyl methacrylate in the purchase specification. Ask whether the material is a homopolymer, a copolymer or a blend, and identify additives and residual monomer. Specify powder, beads or granules, particle-size distribution, moisture, colour and packing. Avoid accepting a generic acrylic-resin description in place of the agreed chemistry.

Agree the solvent and preparation method used to measure solution viscosity, including concentration and temperature. Compare dissolution, clarity and film behaviour with an approved sample in your own process. Request a batch certificate of analysis and retain a sample from the delivered lot.

Confirm with HSE whether the actual resin qualifies for a UK REACH polymer registration exemption and what obligations apply to its monomers and additives. Hazardous chemicals supplied for workplace use require a safety data sheet. Review the actual formulation rather than treating a possible polymer exemption as a complete compliance position.

Worked duty example

Illustrative example, not a quote: Illustrative order: 1 tonne of polyethyl methacrylate resin powder under 3906 90 90 90, invoiced at £45,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £46,500. Duty at 6% is £2,790. Import VAT at 20% is charged on the customs value plus duty, £49,290, so it is £9,858. Import taxes total £12,648; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £2,790 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: check the product name, manufacturer, grade and batch against the order and certificate of analysis.

Powder or beads: check particle distribution, caking, discolouration, foreign particles and consistency with the approved sample.

Solution trial: check dissolution, viscosity and clarity using the agreed solvent and preparation method.

Packing: check seals, liners, moisture damage and batch labels; retain samples before releasing stock. Arrange checks through the quality inspection guide.

What goes wrong

An acrylic trade name can conceal a different polymer or a changed blend. A sample may dissolve clearly while the delivered lot leaves particles or gives a different viscosity. Compare the delivered material using the same preparation method before committing it to production.

Caking, contamination and moisture-damaged packaging can make handling inconsistent. Keep affected bags separate while investigating. Another costly error is assuming every transparent acrylic resin receives the suspension: cost the order at the ordinary rate unless eligibility has been confirmed.
