Sourcing centrifugal pump impellers from China
Separately supplied centrifugal pump impellers fall within the other pump parts line, carrying 0% UK duty from China. Match the drawing, material and shaft fit, and document whether the impeller is a replacement spare or intended for new manufacture. Cambridge China Bridge sources centrifugal pump impellers.
Duty on separately supplied impellers
Heading 8413 covers pumps for liquids and their parts. Separately supplied centrifugal pump impellers are candidates for 8413 91 00 90, described as other parts of pumps. The table shows different impeller configurations sharing that tariff line, rather than separate tariff subdivisions.
Read from the UK Trade Tariff on 3 October 2026, the other pump parts line carried 0% duty for goods from China. The supplied tariff data records no anti-dumping or countervailing duty, tariff suspension or attached import control for this line.
Confirm the commodity code using the drawing, intended pump and condition in which the goods arrive. An impeller supplied separately should be distinguished from an assembled pump. For the wider product family, see water pumps and circulators.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |

| Open centrifugal pump impellers, supplied separately | 8413 91 00 90 | 0% | None |
Specify the hydraulic shape and shaft connection
Supply a controlled drawing identifying the pump model, impeller configuration, rotation direction and viewing direction. Specify outside diameter, vane geometry, bore, keyway or thread, hub length, wear-ring surfaces and running clearances. Agree dimensional tolerances and balance acceptance before approving production.
Name the liquid, operating temperature, rotational speed and duty point. Specify the material grade, casting or moulding process, surface finish and material evidence. Approve a sample in the intended pump, checking flow, head and vibration rather than accepting appearance alone.
Record whether the order is for replacement spares or new manufacture. GOV.UK guidance says intended spare-part use should be evidenced by documents that can be produced when market surveillance authorities request them. Keep the pump identification and intended use with the purchase specification.
Worked duty example
Illustrative example, not a quote: Illustrative batch of replacement centrifugal pump impellers under 8413 91 00 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 and material: match each batch to the approved drawing revision and material records; check for substitutions.
Fit: measure the bore, keyway or thread, hub faces and wear-ring surfaces; trial-fit samples on the intended shaft.
Casting and balance: inspect vane passages for trapped material, cracks, porosity and burrs; review balance records and any agreed defect testing.
Arrival and performance: check vane edges and machined surfaces for transport damage or corrosion, then run an approved sample in the intended pump. Arrange quality inspection around these checks.
What goes wrong
An impeller can fit the shaft yet deliver the wrong flow or head because its vane shape, diameter or rotation differs. Poor balance causes vibration, while incorrect hub dimensions or clearances can cause rubbing. Material substitutions and casting defects can shorten service life.
Do not approve a replacement from a photograph alone. Compare the drawing and sample with the original pump, agree how defects will be assessed, and repeat the pump performance check after any change to hydraulic geometry or material.

Frequently asked questions
What is the UK import duty on centrifugal pump impellers from China?
The supplied tariff data gives 0% for other pump parts under 8413 91 00 90, with no anti-dumping or countervailing duty. Confirm that line for the actual goods.
What drawing does an impeller supplier need?
Provide vane geometry, outside diameter, bore and shaft connection, hub dimensions, clearances, material and rotation direction with its viewing direction.
How do I check a replacement impeller fits?
Measure the shaft connection and hub faces, trial-fit a sample, check running clearances and test flow, head and vibration in the intended pump.
What paperwork should identify replacement impellers?
Keep documents identifying the intended pump and replacement use. GOV.UK guidance says intended spare-part use should be evidenced for market surveillance authorities.
