Sourcing zinc oxide eugenol cements from China

Dental cement duty and classification

Heading 3006 includes dental cements and other dental fillings under 3006 40 00 00. The table shows product presentations sharing that tariff line, rather than separate commodity codes. For the wider dental cement context, see the glass ionomer dental cement guide.

Read from the UK Trade Tariff on 30 September 2026, the dental cement line carried 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls for this line. Medical device requirements still apply when placing the cement on the Great Britain market.

Confirm the commodity code using the finished product's composition, intended dental use and presentation. Specify whether the shipment contains complete cement kits or separate ingredients; do not assume an ingredient receives the finished cement's classification.

Specify the formulation and dental use

State whether the cement is for temporary cementation, temporary filling or another manufacturer-supported dental use. Specify powder-and-liquid or paste presentation, reinforcement, pack contents and dispensing accessories. Ask for the complete formulation and identify the eugenol-containing component; keep eugenol-free alternatives outside this specification.

Agree the mixing ratio, mixing method, working and setting behaviour, removal characteristics and storage conditions against the manufacturer's instructions. Ask for compatibility information for the restorative materials your customers use. Manufacturers must hold clinical data supporting medical device claims, so request evidence covering the exact intended use.

Dental cements are medical devices. Before ordering for Great Britain, check the device class, applicable UKCA or CE marking, conformity documents, MHRA registration and the Chinese manufacturer's UK Responsible Person. Match the product name and formulation across the packs and documents.

Worked duty example

Illustrative example, not a quote: An illustrative trial consignment of powder-and-liquid dental cement kits under 3006 40 00 00, invoiced at £4,000 free on board, with £618 of freight and insurance to the UK. The customs value is £4,618. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £4,618, so it is £923.60. 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: match the cement variant, components, batch details and pack contents against the approved specification and order.

Condition: inspect powder for moisture or caking, liquids for leakage and paste containers for damaged closures or unexpected separation.

Mixing: prepare samples using the supplied instructions and accessories; compare consistency, dispensing and setting behaviour with the agreed acceptance criteria.

Labels and storage: check English instructions, conformity marking, expiry information and agreed remaining shelf life. Review transport conditions against the manufacturer's storage instructions. See quality inspection.

What goes wrong

Problems to watch for include damp powder, leaking liquid bottles, mismatched components and instructions that do not match the supplied formulation. These can produce inconsistent mixes or setting behaviour. Compare arrival samples with the approved sample and keep affected batches separate while the supplier investigates.

A certificate for another cement variant leaves the buyer without matching product evidence. Reconcile the formulation, intended use and conformity documents before shipment, then check the delivered packs again. For document review, see testing and certification.
