Sourcing modelling clay and play dough

0% duty

Read from the UK Trade Tariff on 26 September 2026, modelling pastes including those put up for children's amusement, dental wax and dental impression compounds put up in sets or retail packings, and other plaster-based preparations for dentistry carried 0% duty on goods from China, with no anti-dumping measure. Oven-hardened polymer clays may classify with plastics and ceramic clays with minerals, so confirm the commodity code.

Toy safety and chemicals

Play dough and modelling clay for children under 14 are toys under the Toys (Safety) Regulations 2011, so they need UKCA or CE marking, a declaration of conformity and testing to the EN 71 series, including migration limits for heavy metals under EN 71-3. The regulations also limit preservatives such as methylisothiazolinone and chloromethylisothiazolinone in aqueous toy materials, which is where many water-based doughs fail.

Doughs made with wheat flour need a gluten allergy warning, since children may eat them, and small tubs and accessories need age warnings for under-threes. Dental waxes and impression materials sold for clinical use are medical devices under the Medical Devices Regulations 2002.

Worked duty example

For a made-up shipment of 100,000 tubs of play dough under 3407 00 00 00, add the £2,500 of freight and insurance to the £20,000 free-on-board price and customs sees £22,500. Duty on modelling pastes is zero, leaving import VAT of £4,500, 20% of the customs value. For a VAT-registered buyer that is a cash-flow cost rather than a lasting one. The duty and VAT guide walks through the calculation.

What goes wrong

Modelling pastes fail on preservatives, microbes and drying. Dough with too little preservative grows mould in the tub, while too much of a restricted preservative fails the toy limits, colours stain hands and fabrics, and tubs dry out because lids do not seal. Air-dry clays crack as they dry, polymer clays burn or stay soft at the stated oven temperature, and sets arrive without age warnings or allergen information.

Test samples in an accredited laboratory to EN 71-3 and for restricted preservatives, run a microbiological or storage test for mould, check colour transfer onto skin and fabric, check lid seal and moisture loss over time, test drying and curing against the instructions, and check toy markings, age and allergen warnings on every pack.
