Sourcing foam sheet and plastic laminates from China
Plastic foam sheet and boards from China, in PVC, polyurethane, polyethylene or polystyrene, and laminated sheet such as high-pressure laminates, pays 6% UK duty, with no anti-dumping duty. Insulation foam is a construction product, and fire performance matters for any building use. Cambridge China Bridge sources them.

Insulation and fire
Foam boards sold as thermal insulation for buildings are construction products under the retained Construction Products Regulation where a designated standard applies, which means a declaration of performance and UKCA or CE marking. Any sheet used in buildings needs fire classification evidence, and the regulations for external walls restrict combustible materials on relevant buildings, so check the end use first.
Specification
Specify polymer, density, thickness and tolerance, cell structure (open or closed), compression strength, colour and any adhesive backing. For laminates, specify core, surface wear class and thickness. Ask for a UK REACH statement on flame retardants and plasticisers.
Inspection
At inspection, measure thickness and density, check sheet flatness and edges, and weigh bales against the invoice.
Cambridge China Bridge sources foam sheet, insulation boards and plastic laminates, with density, fire evidence and marking settled before the order. See how our sourcing service works.
