Sourcing hydraulic and pneumatic cylinders from China
Hydraulic cylinders and hydraulic systems from China pay 2% UK duty, while other hydraulic motors, pneumatic cylinders and other pneumatic motors pay 4%, and parts, wind turbine blades included, 0%. None has anti-dumping duty. Pressure rating, mounting standard and seals decide whether a cylinder fits your machine. Cambridge China Bridge sources hydraulic and pneumatic cylinders and motors.
Hydraulic cylinders pay 2% UK duty from China, other hydraulic and pneumatic motors and cylinders 4%, parts and wind turbine blades 0%.
Duty by type
Read from the UK Trade Tariff on 25 September 2026, linear acting hydraulic cylinders carried 2% duty on goods from China, other hydraulic power engines and motors 4%, pneumatic cylinders and other pneumatic motors 4%, steam engines 2%, and parts of hydraulic engines, wind turbine blades and other parts 0%. None had an anti-dumping measure.
Hydraulic pumps and valves are in other headings; confirm the commodity code for each item.

Specification
Specify bore, rod diameter, stroke, working and test pressure, mounting style, port threads, seal material and working temperature. Mounting dimensions to a recognised standard, such as the ISO 6020 series for hydraulic cylinders or ISO 15552 for pneumatic cylinders, let a Chinese cylinder replace an existing one.
Ask what the seals are and who makes them, because seal failure is the usual warranty claim.
Machinery safety
Cylinders are usually components built into a machine, so the machine builder's UKCA or CE assessment has to cover them. Ask for pressure test certificates for each batch and material certificates for the barrel and rod.
Testing and inspection
Pressure-test samples, check leakage and rod surface finish, and measure stroke and mounting points. At inspection, check port threads, plugs and packing to keep dirt out.
Cambridge China Bridge sources hydraulic and pneumatic cylinders and motors, with pressure, mounting and seal questions settled before the order. See how our sourcing service works.
