Sourcing hydraulic accumulators from China
The selected hydraulic accumulator and parts lines carry 0% UK duty for goods from China, with no trade remedies recorded. The pressure equipment conformity procedure depends on classification, so agree the applicable route before ordering. Cambridge China Bridge sources hydraulic accumulators.

UK duty on hydraulic accumulators
Heading 8479 covers machines and mechanical appliances with individual functions not specified elsewhere in the chapter, and their parts. The selected lines are candidates for complete hydraulic accumulators and relevant parts, rather than interchangeable codes. Compare related equipment in hydraulic and pneumatic cylinders.
Read from the UK Trade Tariff on 4 October 2026, the selected lines carried 0% ordinary duty for goods from China, with no anti-dumping or countervailing duties or suspensions recorded. The complete-equipment candidate carries fluorinated greenhouse gas and waste import controls; the other-parts candidate carries the gas control. Confirm the requirements for your actual goods with your customs broker, including the recorded waste export control if re-export is planned.
Confirm the commodity code using the construction, function, gas contents and whether the shipment contains a complete accumulator or parts. Do not classify every bladder, seal or vessel under the same parts code merely because it belongs to an accumulator.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Complete hydraulic accumulators, subject to classification | 8479 89 97 90 | 0% | None |
| Cast iron or cast steel accumulator parts, subject to classification | 8479 90 20 90 | 0% | None |
| High-pressure seamless steel gas cylinders, including bladder-fitted types | 8479 90 70 60 | 0% | None |
| Other accumulator machine parts, subject to classification | 8479 90 70 99 | 0% | None |
Specify the vessel, bladder and pre-charge
State whether you need a bladder, piston or diaphragm accumulator. Specify usable capacity, maximum allowable pressure, operating temperature, hydraulic fluid, seal and bladder materials, mounting orientation, port threads and gas charging connection. Give the supplier your mating connection drawing and agree the pre-charge condition at dispatch.
For pressure equipment, the applicable conformity assessment procedure depends on its classification. Ask the supplier to explain the route for the actual model and supply the supporting documents for review before ordering. CE marking remains recognised indefinitely in Great Britain. Request model-specific instructions, pressure test records, material records and a replaceable-parts list.
Worked duty example
Illustrative example, not a quote: 40 hydraulic accumulators for machinery maintenance stock; illustrative only under 8479 89 97 90, invoiced at £8,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £9,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £9,200, so it is £1,840. 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 the vessel marking, model and serial identification to the order and supporting records; check for transport damage and corrosion.
Connections: check port threads, sealing faces, mounting dimensions and charging valve compatibility against the approved drawing.
Pressure records: match test records to the delivered vessels; have a competent technician verify pre-charge against the agreed condition using suitable equipment.
Materials and cleanliness: verify bladder and seal materials against the specified fluid; inspect capped ports and packaging for contamination. Agree these checks in the inspection brief.
What goes wrong
A vessel can fit the mounting space but have the wrong port thread, unsuitable bladder material or an inaccessible charging valve. A substituted seal or incorrect pre-charge can undermine the agreed performance. Record approved materials and settings in the order, and require written agreement before substitutions.
A generic certificate may describe a different vessel or pressure rating. Match the paperwork to the delivered model and keep damaged or unidentified units out of installation while the supplier resolves the discrepancy.

Frequently asked questions
What is the UK import duty on hydraulic accumulators from China?
The selected complete-equipment and parts lines under heading 8479 carry 0% ordinary duty for China, with no trade remedies recorded. Confirm the exact code before declaring.
Can I buy a hydraulic accumulator using only its capacity?
Specify pressure, fluid, temperature, bladder or seal material, port threads, mounting and pre-charge as well as capacity.
Does a CE mark settle the accumulator conformity checks?
CE marking remains recognised in Great Britain, but ask for the classification, applicable assessment route and supporting documents for the actual model.
What should I check when the accumulators arrive?
Match vessel identification and test records, inspect ports and transport damage, and have a competent technician verify the agreed pre-charge condition.
