Sourcing silicone bakeware from China

Duty and the attached declaration control

Read from the UK Trade Tariff on 3 October 2026, heading 3924 covers tableware, kitchenware, other household articles and hygienic or toilet articles of plastics. This guide concerns silicone bakeware proposed for the other kitchenware line, 3924 10 00 90. The table shows product examples sharing that line, rather than separate tariff subdivisions.

The supplied tariff facts give 6% duty for goods from China under 3924 10 00 90, with no anti-dumping or countervailing duty and no suspension listed. The UK Trade Tariff attaches a restriction on entry into free circulation referring to a plastics declaration of compliance. The importer should confirm with their customs broker whether that requirement applies to the exact silicone construction.

Give the broker the formulation, reinforcement and details of every food-contact component before confirming the commodity code. Official guidance requires a declaration and laboratory report for each consignment within the Chinese polyamide and melamine kitchenware control. Ask the broker to check that control if either material is present. See the wider homeware and kitchenware guide.

Specify the silicone and the baking conditions

Specify the silicone formulation, colourants, curing and post-curing process, reinforcement, cavity dimensions, wall thickness and rim stiffness. For reinforced baking mats, ask how cut edges are sealed. Agree an approved sample and require the factory to seek approval before changing the formulation, pigment or construction.

Food-contact materials must be safe and suitable for their intended use. Ask a laboratory to assess the finished product under the intended food types, contact duration, baking conditions and repeated use. Request reports identifying the actual formulation and colour, rather than accepting a generic food-grade claim. Agree cleaning instructions, supported temperature claims and any need for a supporting baking tray.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2,000 silicone cake moulds, assuming this classification is confirmed under 3924 10 00 90, invoiced at £7,000 free on board, with £600 of freight and insurance to the UK. The customs value is £7,600. Duty at 6% is £456. Import VAT at 20% is charged on the customs value plus duty, £8,056, so it is £1,611.20. Import taxes total £2,067.20; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £456 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Material: match the batch and colour to the approved sample and reports; check for persistent odour, tackiness and surface residue.

Moulding: measure cavities and wall thickness; inspect rims, seams and corners for tears, flash and thin patches.

Baking trial: check release, shape retention and handling with the agreed tray; compare performance before and after repeated baking and cleaning.

Packing: check that mats lie flat, moulds recover after unpacking, and instructions match the approved use. Plan checks with the quality inspection guide.

What goes wrong

Watch for rims that collapse when filled, moulds that distort, tearing during release, sticky surfaces and odour after heating. Baking mats can arrive permanently creased or with exposed reinforcement at their edges. Trial production samples in use rather than judging only their appearance.

A report for a different formulation or colour leaves the supplied product unassessed. Keep the approved sample, formulation and report linked to the order, and review changes before shipment. Discuss the test scope through testing and certification.
