Sourcing photopolymer plates from China

Duty on unexposed photopolymer printing plates

Read from the UK Trade Tariff on 8 November 2026, heading 3701 covers sensitised, unexposed photographic plates and film in the flat, excluding paper, paperboard and textile materials. This guide concerns photosensitive photopolymer printing plates supplied before exposure. See the wider photographic and X-ray film guide for the other products in this heading.

The supplied tariff snapshot records 0% duty for goods from China on every line, with no anti-dumping or countervailing measures, suspensions or attached import controls. Plates with any side exceeding 255 mm fall within 3701 30 00 00; other relevant unexposed plates may fall within 3701 99 00 00. The table repeats the larger-sheet code for different processing formats.

Confirm the commodity code using sheet dimensions, backing material and whether the plate is sensitised and unexposed. Do not use this guide to classify an already exposed or finished printing plate. Keep the manufacturer's description with the purchase specification.

Match the plate to your exposure and washout process

Specify sheet dimensions, total thickness, backing, hardness and target relief depth. State whether you need analogue exposure or digital imaging, and solvent washout, water washout or thermal processing. Ask the factory to identify the exact grade and provide its exposure, processing, drying and finishing instructions.

Approve samples through your own plate-making equipment and a print trial using the intended ink and substrate. Compare fine detail, solids, registration and mounting adhesion. Agree storage conditions, remaining shelf life at dispatch and protective packaging before approving the production batch.

UK REACH generally applies to substances on their own, in mixtures and in articles. Obtain composition and safety information to assess the applicable duties. If the order includes hazardous processing chemicals supplied for workplace use, safety data sheets are required; assess those chemicals separately from the plates.

Worked duty example

Illustrative example, not a quote: Illustrative trial batch of unexposed photopolymer printing plates under 3701 30 00 00, invoiced at £3,000 free on board, with £255 of freight and insurance to the UK. The customs value is £3,255. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £3,255, so it is £651. 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

Dimensions and thickness: measure sample sheets across the batch against the approved specification, including flatness and backing condition.

Processing trial: expose and process batch samples using the agreed settings; compare relief, fine detail, tack and print results with the approved sample.

Batches and shelf life: match grade and batch identifiers on packs to the order and factory records; check expiry against the agreed remaining shelf life.

Packaging: check light-tight seals, protective films and sheet separation; look for scratches, pressure marks, curled edges and damp cartons. Use the quality inspection guide to define the inspection brief.

What goes wrong

A plate can match the ordered thickness yet fail in the buyer's process. The wrong washout grade, unsuitable exposure settings or incomplete drying can produce poor relief, lost detail or unstable printing. A supplier's processed sample is less useful than a trial made on the equipment that will handle the shipment.

Light leaks, heat, old stock and damaged backing can undermine an otherwise acceptable grade. Ask for batch samples before dispatch, record the approved processing settings and investigate changes in results before accepting a replacement formulation.
