Sourcing water pumps and circulators from China

Zero duty

Read from the UK Trade Tariff on 25 September 2026, single-stage and multi-stage submersible pumps, glandless impeller pumps for heating systems and warm water, radial flow and other centrifugal pumps, and other pumps for liquids carried 0% duty on goods from China, with no anti-dumping measure.

Pumps are dense and ship well by sea; confirm the commodity code by pump type and outlet diameter, since the tariff splits centrifugal pumps that way. For the reverse trade route, see exporting UK pumps to China.

Circulator efficiency

Great Britain retained Regulation 641/2009 on glandless standalone circulators and circulators integrated in products. Annex I set an energy efficiency index of no more than 0.27 for standalone circulators from 1 January 2013, and of no more than 0.23 for standalone and integrated circulators from 1 August 2015. Ask the factory for the EEI test result for each model and check the value on the nameplate.

Clean water pumps and pumps for other liquids have their own requirements and standards, so name the liquid, temperature and duty point in the product specification and ask which rules the factory has tested against. For lubrication applications, see our centralised lubrication pump sourcing guide. For dosing applications, see our solenoid diaphragm metering pump guide. For rotary lobe models, see our rotary lobe pump sourcing guide. For concrete pumping applications, see our concrete pump sourcing guide. For aggregate washing applications, see our aggregate washing plant sourcing guide.

Duty point and materials

A pump is bought on its curve: the flow at a given head. Give the factory the duty point and the liquid, and ask for the performance curve and a test at that point on production pumps. Materials follow the liquid: cast iron for heating water, stainless steel for clean or aggressive water, and seals rated for the temperature.

Pumps that carry drinking water are water fittings, so the Water Fittings Regulations and the approval evidence installers ask for apply.

Worked duty example

Suppose, purely for illustration, you import 3,000 glandless heating circulators under 8413 70 30 00. At £90,000 free on board and £3,000 to ship and insure, the customs value is £93,000. With 0% duty on circulators, the only charge is import VAT: 20% of £93,000, or £18,600. VAT-registered businesses usually recover that in their next return. Circulators are small and dense, so freight is a small share of the value. The method is set out in how UK import duty and VAT work.

Inspection checklist

Performance: test flow, head, power input and efficiency at the duty point and two other points on sampled pumps by the methods of ISO 9906, and agree beforehand which acceptance grade of that standard applies.

Pressure and electrics: pressure-test every pump casing at the agreed test pressure with no leakage at the seal or joints, and check end-of-line electric strength and earth continuity records for each unit.

Circulators and noise: for heating circulators, ask for the energy efficiency index calculation by the method of BS EN 16297-1 and -2 for the model, and measure noise to ISO 20361 and vibration against ISO 10816-7 on sampled pumps.

What goes wrong

Pumps fail on seals, performance and electrics. Mechanical seals weep after weeks, run-capacitors fail and the pump hums without starting, and impellers cavitate and get noisy because the curve falls short of the duty point. Circulators carry an energy efficiency index on the nameplate that the factory test does not support, and submersible pumps leak at the cable entry, so water reaches the motor.

Run and pressure test every pump, measure flow and head at the duty point on samples against the published curve, check noise and vibration, ask for the EEI test report per circulator model and compare it with the nameplate, check electrical safety evidence to BS EN 60335-2-41 for pumps or BS EN 60335-2-51 for heating circulators, and immersion-test submersible cable glands.

Testing and spares

Ask for a run test and a pressure test on every pump, and check noise, leakage and the motor at inspection. Seals, impellers and capacitors are the parts that fail, so order them with the first shipment. For replacement impeller sourcing, see our centrifugal pump impellers guide.
