Sourcing prosthetic socket liners from China
Prosthetic socket liners confirmed within heading 9021 carry 0% UK duty from China, with no trade remedies recorded. Before GB sale, settle the medical-device conformity route, manufacturer’s UK responsible person and device registration. Check sizing and suspension compatibility before production. Cambridge China Bridge sources prosthetic socket liners.
Zero duty, with classification to confirm
Heading 9021 covers orthopaedic appliances, artificial body parts and other appliances compensating for disability. This guide concerns the liner between the residual limb and prosthetic socket. The tariff file has no liner-specific entry: the table repeats the broad other-appliances line for relevant liner designs, subject to confirmation. For the wider product family, see prosthetic limbs.
Read from the UK Trade Tariff on 7 October 2026, all supplied lines carried 0% duty for goods from China, with no anti-dumping or countervailing duty and no suspensions recorded. The proposed other-appliances line has cat and dog fur import and export controls attached. Imports and exports of that fur and products made from it are banned. Specify synthetic liner materials and confirm the applicable customs declaration with your broker.
Send the broker the intended purpose, material composition, construction and suspension interface before confirming the commodity code. Do not treat the repeated table entries as separate tariff subdivisions or a binding classification. The hypothetical order values are illustrative; use the import duty and VAT guide to plan the calculation.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Cushion socket liners, subject to classification confirmation | 9021 90 90 00 | 0% | None |
Specify liner fit and suspension together
Specify silicone or other gel material, fabric covering, circumference measurement points, length, wall-thickness profile and distal cushioning. Distinguish cushion, pin-lock and seal-in designs. For locking liners, agree the distal attachment and compatible lock; for sealing liners, agree seal geometry and the intended socket interface. Approve samples against the buyer’s actual prosthetic system.
For GB sale as a medical device, manufacturers must meet the relevant marking and conformity assessment requirements. An overseas manufacturer must appoint a UK responsible person, and devices must be registered with the regulator before placement on the GB market. Agree the intended purpose and request documents identifying the actual liner models. Arrange testing and certification support around the final materials and construction.
Worked duty example
Illustrative example, not a quote: Illustrative mixed-size batch of prosthetic socket liners, assuming this code is confirmed under 9021 90 90 00, invoiced at £10,000 free on board, with £900 of freight and insurance to the UK. The customs value is £10,900. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £10,900, so it is £2,180. 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: compare circumference, length, thickness profile and distal shape with the approved drawings and samples; check that size labels match the pieces.
Skin-contact surface: inspect for voids, inclusions, sharp moulding edges, tackiness and uneven curing; request biological evaluation evidence covering the supplied formulation.
Suspension interface: check distal attachment security, pin alignment or seal geometry against the agreed system; examine fabric bonding after stretching and cleaning.
Documents and packing: match model and batch identification to the supplied records, approved instructions and artwork; inspect for cuts, permanent deformation and contamination on arrival.
What goes wrong
A liner can match the labelled size yet differ in circumference, distal shape or thickness distribution. The resulting fit may slip, bunch or concentrate pressure. A locking insert can loosen, sealing geometry can mismatch the socket, and fabric can peel from the gel. Check production samples against the agreed system and cleaning method during quality inspection.
Material substitutions make an approved sample a poor reference for the delivered batch. Generic reports may cover another formulation or model. Tie the material specification, test evidence and device documents to the supplied product, and agree how the factory will obtain approval for changes.

Frequently asked questions
What is the UK import duty on prosthetic socket liners from China?
The supplied heading 9021 lines all carry 0% duty for China, with no anti-dumping or countervailing duty recorded. Confirm the liner’s exact commodity code before shipment.
Can I use the supplier’s commodity code for socket liners?
Have your broker check it against the liner’s intended purpose, materials and construction. The tariff file has no entry specifically named prosthetic socket liners.
What documents should I request before selling liners in Great Britain?
Request the applicable conformity documents, evidence of device registration and the overseas manufacturer’s UK responsible person details, all linked to the supplied models.
How do I check a pin-lock liner before ordering?
Agree the distal attachment, compatible lock, size chart and thickness profile. Test an approved sample with the intended system, then check production pieces against that sample.
