Duty on dental impression plaster
Read from the UK Trade Tariff on 30 September 2026, heading 3407 covers modelling pastes, dental wax and impression compounds in the specified presentations, and other dental preparations based on plaster of calcined gypsum or calcium sulphate. This guide concerns dental impression plaster preparations.
The supplied tariff record contains a single commodity line, 3407 00 00 00, carrying 0% duty for goods from China. It lists no anti-dumping or countervailing duty, tariff suspension or attached import control. Confirm with MHRA whether the intended clinical-use impression material is a medical device; if it is, tariff clearance does not replace device registration.
Confirm the formulation and intended use through the commodity code guide. For the wider product family, see dental impression compounds.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Plaster-based dental impression preparations | 3407 00 00 00 | 0% | None |
Specify impression use and setting behaviour
Specify plaster intended for taking dental impressions, rather than accepting a supplier's general dental gypsum description. Agree the composition, powder fineness, water-to-powder ratio, mixing method, working time, setting time, dimensional change and removal behaviour. Obtain instructions for the exact formulation and compare trial mixes with an approved sample.
Confirm with MHRA whether the intended clinical-use impression material is a medical device. If it is, before placement on the Great Britain market, the device must be registered with MHRA and a Chinese manufacturer must appoint a UK Responsible Person. Obtain the manufacturer's device classification, conformity declaration and clinical-use instructions before approving the order.
Agree sealed moisture-resistant packaging, batch identification, storage conditions and remaining shelf life on delivery. Include a repeatable mixing and impression-release trial in the purchase specification.
Worked duty example
Illustrative example, not a quote: Illustrative wholesale order of sealed dental impression plaster packs 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 that the shipped formulation, intended impression use and batch documents match the approved product.
Powder and packaging: check seals, net contents, moisture damage, hard lumps and contamination; retain an unopened batch sample.
Mixing and setting: follow the supplied water ratio and mixing instructions; compare consistency, working time, setting time and surface detail with the approved sample.
Removal and documents: trial release from an agreed test impression, checking breakage and residue; match instructions and MHRA registration details to the supplied device.

What goes wrong
Moisture exposure can leave powder lumpy and make mixing or setting inconsistent. Changes in formulation or powder fineness can alter flow and working time. Reject unexplained differences from the approved sample rather than adjusting the mixing instructions to accommodate the shipment.
A supplier may substitute model-making plaster for an impression formulation, or supply documents for a different product. Check intended use and document identity before shipment, then repeat the agreed mixing and release checks on arrival. Use testing and certification support to define the evidence needed.
