Sourcing raw stainless orthodontic wire from China
Raw stainless steel orthodontic wire coils from China carry 0% UK duty across heading 7223. MHRA guidance says raw materials are not normally medical devices, but buyers should review the intended use before treating a coil as manufacturing stock. Cambridge China Bridge sources raw stainless steel orthodontic wire coils.
Duty on raw stainless steel wire coils
Read from the UK Trade Tariff on 1 October 2026, heading 7223 covers wire of stainless steel. This guide concerns raw coils bought for further manufacturing. For 304 or 316 wire, check 7223 00 19 00 against the mill chemistry. The table shows the heading's chemistry branches, not a recommendation that every listed alloy suits orthodontic manufacture. See the wider stainless steel wire guide.
Every supplied line carries 0% duty for goods from China. The supplied record lists no anti-dumping or countervailing duty, steel measure or suspension. It attaches waste import and export controls. For a China-to-England shipment subject to waste notification controls, the exporter must apply to the dispatch country's competent authority for consent. Ask your customs broker to confirm the waste-control requirement for the actual goods, including any proposed return shipment.
Confirm the commodity code using the composition certificate, wire form and description of the goods as imported. Describe raw manufacturing coils accurately rather than relying on the supplier's word 'orthodontic'. The worked order is illustrative, not a quotation; see UK import duty and VAT for the calculation method.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other wire with nickel at least 2.5%, including 304 and 316 | 7223 00 19 00 | 0% | None |
| Other wire with nickel below 2.5% | 7223 00 99 00 | 0% | None |
| Wire with nickel 28% to 31% and chromium 20% to 22% | 7223 00 11 00 | 0% | None |
| Wire with nickel below 2.5%, chromium 13% to 25%, aluminium 3.5% to 6% | 7223 00 91 00 | 0% | None |
Specify the alloy, temper and manufacturing use
State the intended manufacturing process, alloy chemistry, round or rectangular section, dimensions and tolerances, tensile strength, elongation, temper and surface finish. Agree coil weight, winding direction, spool dimensions and permitted joins. Ask for a heat-specific mill certificate and samples for your bending, forming and joining trials.
MHRA guidance says raw materials and intermediate products are not normally medical devices. Treat that as a starting point for review, rather than assuming every coil described as orthodontic is outside device rules. Have the intended purpose, labelling and clinical claims reviewed before ordering, especially material offered for patient-specific appliances.
UK REACH generally applies to substances on their own, in mixtures or in articles. Ask your compliance adviser to assess the alloy and any coating or drawing residue. Request composition and surface-treatment information from the supplier; a grade name alone is insufficient for that review.
Worked duty example
Illustrative example, not a quote: Illustrative trial batch of raw stainless steel orthodontic wire coils under 7223 00 19 00, invoiced at £4,000 free on board, with £1,100 of freight and insurance to the UK. The customs value is £5,100. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £5,100, so it is £1,020. 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 coil tags, heat numbers and certificates; check composition against the ordered alloy.
Section: measure diameter or width and thickness along sample lengths; check ovality, twist and agreed tolerances.
Mechanical behaviour: check tensile strength and elongation, then trial bending and forming against the approved sample.
Surface and winding: inspect for scratches, burrs, rust, residues, kinks, hidden joins and tangled turns; check protective packing.

What goes wrong
A correct alloy can still fail because its temper produces the wrong springback, its rectangular section twists during forming, or drawing marks remain after finishing. Mixed heats, unreported joins and certificates that do not match coil tags make failures harder to trace. Agree acceptance checks before production and use a quality inspection plan tied to the intended process.
Do not let a material certificate become the sole basis for accepting a clinical-use claim. Keep the raw-material purchasing brief separate from your finished-product assessment. Confirm with HMRC whether heading 7223 will be covered by the UK carbon border adjustment mechanism from 1 January 2027, using the published UK CBAM guide as a reference; request supplier emissions data when planning future imports.

Frequently asked questions
What is the UK import duty on raw orthodontic wire coils from China?
The supplied UK Trade Tariff record shows 0% on every heading 7223 line, with no listed anti-dumping or countervailing duty, steel measure or suspension.
Which commodity code covers 304 or 316 raw wire coils?
Check 7223 00 19 00 for these grades. Confirm the mill chemistry and the form of the imported goods with your customs broker.
Do raw orthodontic wire coils need CE or UKCA marking?
Do not decide from coil form alone. MHRA says raw materials are not normally medical devices; have the intended purpose, labelling and clinical claims reviewed before ordering.
What should I ask the Chinese wire factory for?
Ask for heat-specific chemistry and mechanical results, dimensional tolerances, temper, surface-treatment details, coil identification and samples for your forming trials.
