Sourcing dental impression compound from China

Dental impression compound: 0% duty

Read from the UK Trade Tariff on 24 October 2026, heading 3407 covers dental impression compounds put up in sets, retail packings, plates, horseshoe shapes, sticks or similar forms. It also covers modelling pastes, dental wax and certain plaster-based dental preparations.

The supplied record gives 3407 00 00 00 a duty of 0% for goods from China, with no anti-dumping or countervailing measure, suspension or attached import control recorded. It contains only this commodity line, so the table uses it once.

Confirm the formulation, intended use and presentation through finding your commodity code. See modelling clay and play dough for the wider heading. The tariff classification does not replace the medical device checks for clinical supply.

Specify the compound and clinical purpose

Specify heat-softened dental impression compound, its intended clinical purpose, composition, colour and presentation. Agree the softening method, working behaviour, cooling behaviour, detail reproduction and dimensional stability against an approved sample. Ask for instructions covering handling, storage and any compatible cleaning or disinfection process.

Confirm with MHRA whether the clinical dental impression materials fall under medical device rules. Registration with MHRA is required before placing a medical device on the Great Britain market. A manufacturer based outside the UK must appoint a single UK Responsible Person. Ask the supplier for evidence identifying the manufacturer, representative and exact product before approving the order.

Worked duty example

Illustrative example, not a quote: Illustrative order of boxed dental impression compound for a dental distributor under 3407 00 00 00, invoiced at £20,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £22,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £22,500, so it is £4,500. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.

Inspection checklist

Identity: check the shipped formulation, colour, shape and pack description against the approved specification and sample.

Handling: soften samples using the supplied instructions and compare uniformity, stickiness, working behaviour and cooling with the approved sample.

Impression performance: use an agreed test model to check detail reproduction, distortion after cooling and cracking during removal.

Packaging and documents: check seals, contamination, batch identification, shelf-life information and storage instructions. Match registration evidence and product documents to the actual manufacturer and product supplied.

What goes wrong

A compound can match the sample colour yet soften unevenly, become too sticky, turn brittle after cooling or distort during removal. Changes in formulation and uncontrolled storage can undermine the agreed handling behaviour. Compare production samples with the approved sample and repeat the agreed model test on arrival.

Another failure is receiving paperwork for a different manufacturer or impression material. Hold the order until the product identity and registration evidence match. Agree the document review and performance checks before production through testing and certification.
