Sourcing PVC foam boards from China

PVC foam board duty and controls

Read from the UK Trade Tariff on 30 October 2026, heading 3921 covers other plastic plates, sheets, film, foil and strip. Cellular PVC sheet under 3921 12 00 90 carries 6% duty from China, with no anti-dumping or countervailing duty recorded. The table shows board applications sharing this tariff line, rather than separate commodity codes.

The recorded 0.00 % suspension applies under authorised-use customs supervision to manufacturing rotor blades for offshore wind turbines. It is not a general discount for signage boards. The tariff also attaches a restriction on entry into free circulation concerning ozone-depleting substances. Ask the factory to identify the blowing agent and confirm the declaration requirement for this Chinese shipment with your customs broker.

Confirm the commodity code using the composition, cellular structure, facings and processing of the supplied board. The foam sheet and laminates guide covers the wider heading.

Specify the core, surface and intended use

Specify PVC composition, recycled content, apparent density, sheet dimensions, thickness tolerances, colour and surface finish. Agree whether the board has a harder surface skin or a uniform foamed structure. Send the factory your printing, cutting and fastening requirements, and approve a sample using your actual inks, adhesives and tools.

For building use, obtain fire classification evidence matching the board's density, thickness and facing. For boards sold as building insulation, confirm with the relevant construction products authority whether a declaration of performance and UKCA or CE marking are required for the applicable standard. UK REACH restrictions can cover substances in articles, so request an additive declaration and assess applicable restrictions before sale.

Worked duty example

Illustrative example, not a quote: An illustrative container order of cellular PVC boards under 3921 12 00 90, 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 thickness across sheets, check length, width and squareness, and compare apparent density with the agreed specification.

Surface and fabrication: compare colour and finish with the approved sample; trial printing, adhesive bonding, cutting and fastening on production boards.

Core and evidence: inspect cut edges for voids or uneven cells, and match any fire report and additive declaration to the supplied grade.

Packing and arrival: check flatness, scratches, crushed corners, protective film and batch identification before loading and on arrival. Use the inspection guide to agree how defects are recorded.

What goes wrong

A board can match the approved colour while differing in density, surface hardness or thickness. Printing may adhere poorly, cut edges may crumble, and fasteners may pull out during fabrication. Approve production-grade samples and record acceptance criteria for the intended job.

Boards also arrive bowed or scratched when bundles lack flat support, surface protection or corner guards. A generic fire report may describe a different thickness or facing. Resolve those mismatches before accepting stock for building use.
