Sourcing dental root canal sealers from China

Zero duty on the dental-filling line

Read from the UK Trade Tariff on 30 September 2026, heading 3006 includes dental cements and other dental fillings under 3006 40 00 00. This is the relevant line to assess for root canal sealers. The table shows supply formats sharing that line, rather than separate tariff subdivisions.

The supplied tariff record gives 0% duty for goods from China on this line, with no listed anti-dumping or countervailing duty, suspension or attached import control. Medical device requirements still apply separately to products placed on the Great Britain market.

Confirm the commodity code using the composition, intended dental use and presentation. For the wider dental-cement category, see glass ionomer dental cements.

Specify the sealer formulation and delivery system

Specify the chemistry, intended root canal use, premixed or mixed presentation, pack contents and dispensing accessories. Agree the manufacturer's claimed working and setting behaviour, storage conditions and remaining shelf life at delivery. Ask for supporting evidence for radiopacity, flow, sealing performance and compatibility with the intended obturation technique.

For sale in Great Britain, dental filling materials need the applicable medical device conformity assessment and product marking, and a UK Responsible Person for the overseas manufacturer. Confirm with the MHRA which UKCA or accepted CE marking route and registration requirements apply before sale. Match the declared intended use and product identity to the conformity documents. Confirm the applicable marking route before approving packaging.

Worked duty example

Illustrative example, not a quote: 500 packs of dental root canal sealer, illustrative order under 3006 40 00 00, invoiced at £4,000 free on board, with £500 of freight and insurance to the UK. The customs value is £4,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £4,500, so it is £900. 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

Documents: check that the product name, formulation and presentation match the conformity declaration, applicable certificates and batch test documents.

Packaging: check caps, seals and syringes for damage, leakage or dried material; match batch references and expiry information across the packs.

Dispensing: check extrusion, accessory fit and mixing against the agreed instructions, using samples rather than saleable stock.

Performance: arrange sample testing against the agreed flow, setting and radiopacity claims; check that transport and storage followed the manufacturer's instructions.

What goes wrong

A sample can dispense smoothly while the shipment contains leaking syringes, blocked tips or inconsistent paste. Mixing kits can arrive with mismatched components or unclear mixing instructions. Documents may cover a different formulation or presentation. Compare shipment samples with the approved specification, retain batch references and resolve discrepancies before releasing stock for sale.
