Sourcing copper-nickel pipe elbows from China
Copper-nickel pipe elbows from China carry 0% UK import duty under the copper-alloy fittings line, with no trade remedies listed. For pressure equipment, the conformity assessment procedure depends on its classification, so settle the intended application before ordering. Cambridge China Bridge sources copper-nickel pipe elbows.
Duty on copper-nickel elbows
Heading 7412 covers copper tube or pipe fittings, including elbows. Copper-nickel elbows belong to the copper-alloy family, rather than the refined-copper line. See the wider copper and brass pipe fittings guide. The supplied tariff file contains only one commodity line relevant to this product family.
Read from the UK Trade Tariff on 30 September 2026, code 7412 20 00 00 carried 0% duty for goods from China. The supplied record lists no anti-dumping or countervailing duty, suspension or attached import control for this line.
Give your customs broker the alloy composition, drawing and description of the finished elbow to confirm the commodity code. For the import tax calculation, see UK import duty and VAT.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Copper-nickel pipe elbows, of copper alloys | 7412 20 00 00 | 0% | None |
Specify the alloy, bend and joint
Specify the copper-nickel alloy designation and composition, manufacturing method, tube outside diameter, minimum wall thickness, bend angle, bend radius and centre-to-end dimensions. Attach a drawing with tolerances. State whether the ends are prepared for butt welding, socket joining or a threaded connection, and identify the mating pipe.
Describe the fluid, service temperature and pressure, and agree the material certificate, dimensional report and sample tests before production. For pressure equipment, the appropriate conformity assessment procedure depends on classification. Ask your technical adviser to establish how the elbow will be supplied and integrated into the system before agreeing conformity documents or marking.
For water fittings in England and Wales, confirm with the water supplier the applicable requirements for quality, standard and suitability for the circumstances of use. If that is the intended application, agree evidence for the exact elbow and alloy rather than accepting a certificate for a different fitting range.
Worked duty example
Illustrative example, not a quote: Illustrative batch of mixed-size copper-nickel pipe elbows under 7412 20 00 00, invoiced at £52,000 free on board, with £2,600 of freight and insurance to the UK. The customs value is £54,600. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £54,600, so it is £10,920. 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
Material: match batch markings to the material certificate and purchase specification. Arrange independent composition checks where alloy identity is critical.
Geometry: measure bend angle, radius, centre-to-end dimensions and end ovality against the drawing. Check wall thickness around the bend, including the outer curve.
Joint preparation: check end diameter, bevel or socket dimensions, burrs and surface condition. Trial-fit samples with the specified mating pipe and agree joint testing with the system designer.
Arrival and packing: check for dents, flattened ends, contamination and mixed sizes. Keep batch identification with the parts and record discrepancies during quality inspection.

What goes wrong
An elbow can fit the nominal pipe size yet miss the required bend radius or centre-to-end dimension. Thin walls around the outer bend, oval ends and inconsistent joint preparation can cause assembly or test failures. An alloy certificate without matching batch identification leaves the delivered material uncertain.
Approve a measured sample against the drawing, retain its inspection record and agree how rejected parts will be handled. Ask for packing that separates sizes and protects prepared ends. Recheck geometry and identification on arrival before releasing the batch for fabrication.

Frequently asked questions
What is the UK import duty on copper-nickel elbows from China?
The supplied tariff record shows 0% under 7412 20 00 00, with no anti-dumping or countervailing duty listed.
What should I put on a copper-nickel elbow drawing?
Show the alloy, outside diameter, wall thickness, bend angle and radius, centre-to-end dimensions, end preparation and tolerances. Identify the mating pipe.
Do copper-nickel elbows need pressure equipment assessment?
For pressure equipment, the procedure depends on classification. Ask your technical adviser to assess the intended supply and system integration before agreeing documents or marking.
How do I check that the factory supplied the right alloy?
Match the material certificate to the ordered composition and the batch markings on the elbows. Agree independent composition testing where alloy identity is critical.
