Sourcing stainless expansion joints from China
Stainless-steel pipeline expansion joints from China carry 0% UK duty when classified under 8307 10 00 90. Pressure-equipment rules can apply above 0.5 bar; check the conformity route for the intended service before sale in Great Britain. Cambridge China Bridge sources stainless-steel pipeline expansion joints.
Duty and classification for pipeline expansion joints
Read from the UK Trade Tariff on 30 September 2026, heading 8307 covers flexible tubing of base metal, with or without fittings. Stainless-steel pipeline expansion joints classified as flexible steel tubing fall under 8307 10 00 90. The table shows product variants using this single tariff line, rather than separate commodity lines.
The supplied record gives 0% duty for goods from China under this code, with no anti-dumping or countervailing duty, suspension or attached import control recorded. This tariff result does not establish suitability for pressure service.
Send your customs broker the assembly drawing, bellows material, end connections and operating description to confirm the commodity code. For the wider heading, see flexible metal hoses.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Stainless-steel axial bellows expansion joints, if classified as flexible tubing | 8307 10 00 90 | 0% | None |
Specify bellows movement and pressure service
State the conveyed fluid, operating and design temperatures, maximum allowable pressure, pipe bore and installation length. Specify axial, lateral and angular movement, expected operating cycles and whether movements occur together. Agree bellows material, wall construction, end connections, flange drilling, internal liner and any tie rods or restraints. Ask the pipeline designer to confirm anchors, guides and pressure-thrust loads.
Pressure-equipment rules can apply where maximum allowable pressure exceeds 0.5 bar. Check the applicable classification and conformity route for the actual assembly before selling it in Great Britain. Government guidance confirms continued recognition of CE marking for pressure equipment in Great Britain. Match any claimed marking to the product and supporting documents through testing and certification support.
Worked duty example
Illustrative example, not a quote: 600 small-bore flanged stainless-steel expansion joints; illustrative order and values under 8307 10 00 90, invoiced at £24,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £25,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £25,500, so it is £5,100. 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
Dimensions: measure bore, face-to-face length, flange drilling and weld-end dimensions against the approved drawing; inspect bellows for dents, distorted convolutions and misalignment.
Materials and welds: match material certificates to batch identification; compare bellows, flange and liner materials with the specification, and review the agreed weld inspection records.
Performance: review pressure, leak and movement test records for the supplied design and batch; check that test conditions match the agreed duty rather than a different catalogue model.
Packing and documents: check restraint settings, liner direction, protected sealing faces and installation instructions against the order. Keep transit restraints identifiable and arrange a shipment inspection.

What goes wrong
A joint can fit the pipe yet be unsuitable for its movement or temperature. Bellows may crack when movement exceeds the design allowance, while thin or substituted material can reduce fatigue life. Poor welds can leak, damaged flange faces can prevent sealing, and an incorrectly oriented liner can interfere with movement.
Unrestrained pressure thrust or unsuitable anchors and guides can overload the joint and adjacent pipework. Do not use the bellows to pull misaligned pipes into position. Approve the installation drawing alongside the product drawing, and check factory forming, welding and testing capability through factory verification.

Frequently asked questions
What is the UK import duty on stainless-steel expansion joints from China?
The supplied tariff record shows 0% under 8307 10 00 90, with no anti-dumping or countervailing duty recorded. Confirm that the actual joint is classified as flexible steel tubing.
What specifications should I send to the Chinese factory?
Send fluid, pressure, temperature, bore, installation length, movement requirements and expected cycles. Include material, flange or weld-end drawings, liner details and the required restraint arrangement.
Do stainless-steel expansion joints need pressure-equipment checks?
Pressure-equipment rules can apply above 0.5 bar maximum allowable pressure. Check the classification and conformity route for the actual assembly and intended service before sale in Great Britain.
What should I inspect when expansion joints arrive?
Check dimensions, bellows damage, welds, flange faces, liner orientation and restraint settings. Match material identification and test records to the delivered batch and approved drawing.
