Sourcing melamine foam sheets from China

Duty on melamine foam sheets

Read from the UK Trade Tariff on 20 October 2026, heading 3921 covers other plastic plates, sheets, film, foil and strip. For plain cellular melamine foam sheets, the candidate line is 3921 19 00 99, other cellular plastics. The table shows applications of that same line, rather than separate tariff classifications. See the wider foam sheet guide.

The line carries 6% duty for goods from China, with no recorded anti-dumping or countervailing measure. Its listed suspensions concern specified silicone foam, microporous films and filter strip, rather than ordinary melamine foam sheets. The tariff also attaches an ozone-depleting-substance restriction on entry into free circulation. Confirm the declaration requirement with your customs broker and obtain the factory's material and blowing-agent information.

Confirm the commodity code using the composition, cellular structure, facings and degree of processing. Have adhesive-backed sheets, laminates and finished cleaning articles assessed separately before applying the plain-sheet code.

Specify the melamine foam and its use

State whether the sheets are for cleaning-pad conversion, acoustic lining or thermal insulation. Specify melamine resin foam, density, length, width, thickness, tolerances, colour and any facing or adhesive. Agree a retained sample and a method for checking compression recovery, tearing and loose particles.

For cleaning use, compare wet rubbing, wear and surface marking on the intended substrates. Consumer products should only be sold once compliance with product safety regulations has been demonstrated appropriately. For building use, match fire evidence to the density, thickness and facing supplied. Confirm with the relevant authority whether the building insulation is covered by a designated standard and which declaration of performance and UKCA or CE marking requirements apply.

Worked duty example

Illustrative example, not a quote: Illustrative palletised batch of plain melamine foam sheets under 3921 19 00 99, invoiced at £12,000 free on board, with £3,200 of freight and insurance to the UK. The customs value is £15,200. Duty at 6% is £912. Import VAT at 20% is charged on the customs value plus duty, £16,112, so it is £3,222.40. Import taxes total £4,134.40; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £912 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Dimensions and density: measure sheets across the batch and compare their mass and dimensions with the agreed specification.

Structure and wear: compare cell appearance, compression recovery, tearing and particle shedding with the retained sample; trial cleaning grades on the agreed surfaces.

Evidence: match material declarations and relevant fire or performance reports to the supplied grade, facing and adhesive.

Packing and arrival: check crushed corners, permanent compression, dampness and contamination; open packs and repeat the checks after unpacking. Arrange quality inspection against the approved sample.

What goes wrong

A sample can perform differently from bulk sheets because density, thickness or treatment changes. Cleaning grades may crumble during rubbing or mark delicate finishes. Acoustic sheets can arrive torn or compressed. Record these defects against the agreed sample and acceptance criteria.

A fire report for unfaced foam does not establish the performance of a different adhesive-backed assembly. Resolve report mismatches before shipment. Agree packaging that protects the foam without leaving permanent compression, and keep batches identifiable when unpacking.
