Sourcing polyether impressions from China
Polyether dental impression materials classified under heading 3407 carry 0% UK duty from China. Confirm clinical products' medical-device status with the MHRA; medical devices must be registered with the MHRA before placement on the Great Britain market. Check the formulation, mixing system and supporting documents. Cambridge China Bridge sources polyether dental impression materials.
0% duty on polyether impression materials
Read from the UK Trade Tariff on 30 September 2026, heading 3407 covers modelling pastes, dental wax and dental impression compounds in the specified sets, retail packings or forms, alongside plaster-based dental preparations. This guide focuses on polyether dental impression materials. The product forms shown share the same commodity line.
The supplied tariff record gives 3407 00 00 00 a duty of 0% for goods from China. It lists no anti-dumping or countervailing duty, tariff suspension or attached import control. Confirm with the MHRA whether the dental impression materials intended for clinical use fall within the Medical Devices Regulations 2002.
Confirm the commodity code against the composition, intended use and presentation before ordering. For the wider heading context and a comparison product family, see silicone dental impression materials.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |

| Light-bodied polyether dental impression compounds in retail packs | 3407 00 00 00 | 0% | None |
Specify the polyether formulation and mixing system
Specify polyether chemistry explicitly rather than accepting a generic elastomeric impression material. Agree the consistency, intended impression technique, working and setting behaviour, mixing ratio, dispenser or machine compatibility, matching tips and tray adhesive. Ask for documented storage, disinfection and cast-pouring instructions, with an agreed remaining shelf life at arrival.
Before placement on the Great Britain market, the device must be registered with the MHRA. A manufacturer outside the UK must appoint a UK responsible person to register and act on its behalf. Request evidence covering the actual manufacturer and product supplied, together with its declared conformity route, declaration and applicable certificates.
Manufacturers must hold clinical data supporting their medical-device claims. Ask for the supporting evidence for the intended dental use and formulation, rather than relying on a factory brochure. Agree the document review through testing and certification before approving production.
Worked duty example
Illustrative example, not a quote: Illustrative distributor order of polyether dental impression cartridge sets 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 and documents: match the product name, manufacturer, formulation, consistency and pack variant to the approved specification and supporting device documents.
Mixing and setting: use the specified dispenser and tips on bench samples; check dispensing, uniform mixing, working behaviour and complete setting against the manufacturer's instructions.
Impression performance: compare detail reproduction, elastic recovery, tearing and dimensional stability with the approved sample, including after the specified disinfection procedure.
Arrival condition: check cartridge seals, leakage, component separation, batch identification, expiry information and evidence of the agreed transport conditions; retain samples from the delivered batch.

What goes wrong
Orders can fail when a supplier substitutes another impression chemistry, sends cartridges that do not fit the buyer's mixing equipment or supplies tips that produce uneven mixing. Watch for streaks, unset areas, voids and tearing during bench checks. Approve the complete material, cartridge and tip combination rather than the paste alone.
A good sample does not establish the condition of the shipped batch. Leaking packs, short remaining shelf life or performance changes after disinfection can make stock unsuitable for the agreed use. Hold mismatched stock pending investigation and use the quality inspection guide to define checks before dispatch and on arrival.

Will Chinese polyether cartridges fit my existing dispenser?
Check the cartridge interface, mixing ratio and matching tips against your actual dispenser or machine. Approve a complete combination through bench checks before ordering.
What should I test before accepting a polyether impression batch?
Check mixing, setting, detail reproduction, elastic recovery and dimensional stability against the approved specification. Repeat relevant checks after the manufacturer's specified disinfection procedure.
