Sourcing rubber dental dam sheets from China

Duty on rubber dental dam sheets

Read from the UK Trade Tariff on 30 September 2026, heading 4014 covers hygienic or pharmaceutical articles of vulcanised rubber other than hard rubber, with or without hard rubber fittings. Rubber dental dam sheets fall within the proposed “Other” line, 4014 90 00 00. The table shows purchasing variants sharing that line.

The supplied tariff record gives 0% duty for goods from China, with no listed anti-dumping or countervailing duty, suspensions or attached import controls. That tariff position does not establish medical-device compliance. For the wider rubber hygienic article heading, see rubber breastfeeding nipple shields.

Confirm the composition and intended use with your broker using finding your commodity code, particularly if the supplier offers a non-rubber substitute or a kit containing frames and clamps.

Specify the sheet and its dental use

Agree natural or synthetic rubber, sheet dimensions, thickness tolerance, colour, surface finish and whether sheets arrive punched. Provide an approved sample and agree how the sheet will be stretched and punched during acceptance checks. Request evidence for any latex-free claim and agree the pack quantity, storage instructions and remaining shelf life at delivery.

Confirm whether the product is a medical device before choosing its compliance route. For medical-device supply in Great Britain, manufacturers must meet the applicable marking and conformity assessment requirements; devices must be registered before market placement, and a Chinese manufacturer must appoint a UK responsible person. Ask for the declaration of conformity and confirmation that the supplied model matches the registration. Use testing and certification support to plan the evidence review.

Worked duty example

Illustrative example, not a quote: Illustrative order of 20,000 rubber dental dam sheets under 4014 90 00 00, invoiced at £30,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £32,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £32,500, so it is £6,500. 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. This assumes the goods are standard-rated for VAT. Contraceptive products sold other than on prescription take the reduced rate of VAT under HMRC's VAT Notice 701/57, so check the rate for your product.

Inspection checklist

Material: compare the declared rubber composition and any latex-free claim with the approved specification and supporting documents.

Sheet condition: measure dimensions and thickness against the agreed tolerances; inspect for pinholes, edge cuts, contamination and sheets stuck together.

Handling: punch and stretch sampled sheets using the agreed method; check for tearing around holes and inconsistent recovery against the approved sample.

Packs and documents: reconcile model, batch details, expiry information, instructions and conformity marking with the approved artwork and accompanying records.

What goes wrong

Sheets can tear from cut edges or punched holes, vary in thickness, stick together or become brittle during storage. Agree rejection criteria before ordering and retain samples from accepted batches. A change in rubber compound or processing should trigger a fresh sample review before shipment.

A registration entry is not product approval: registration does not represent accreditation, certification, approval or endorsement by the regulator. Treat documents for another model or a different manufacturer as unresolved evidence, and hold the affected stock while the supplier resolves the mismatch.
