Sourcing refrigeration condensing units from China

UK duty and refrigerant import controls

Heading 8418 covers refrigerating and freezing equipment and certain heat pumps. Refrigeration condensing units usually fall under 8418 69: the assembled compressor and condenser package needs to be distinguished from a separately imported condenser or other replacement part. For related equipment within the wider heading, see industrial process chillers.

Read from the UK Trade Tariff on 7 October 2026, the selected lines carry 0% duty for goods from China, with no anti-dumping or countervailing duty and no listed suspensions. The tariff attaches ozone-depleting substance controls and, on some lines, fluorinated greenhouse gas controls. New refrigeration equipment must not use ozone-depleting substances. Ask your customs broker to confirm the applicable declarations, F-gas labelling and any quota documentation from the refrigerant and charge.

An HFC-pre-charged complete unit is usually 8418 69 00 91; a unit without an HFC charge is usually 8418 69 00 99. The parts rows cover separate imports rather than alternative codes for complete units. Confirm the commodity code using the assembly drawing, intended function and shipping charge. Allow separately for 20% import VAT; see import duty and VAT.

Specify cooling duty and the condenser package

Specify cooling capacity at the intended evaporating temperature and ambient temperature, rather than accepting a compressor power rating as the output. State the refrigerant, whether the unit ships charged or with a holding charge, the compressor model, electrical supply and phase, condenser airflow, pipe connections, receiver arrangement and controller functions. Agree access for coil cleaning and replacement of fans and service valves.

Confirm with the relevant authority or a product-compliance specialist whether the particular condensing unit falls under the ecodesign regime, including Regulation 2015/1095. Request efficiency test results and product information for the exact configuration. Where that regime applies, a declaration of conformity must be supported by technical documentation. For mains-powered equipment, ask the same authority or specialist to confirm the applicable electrical safety declaration and UKCA or CE marking requirements. Put the model, compressor and refrigerant on the documents into the purchase specification.

Worked duty example

Illustrative example, not a quote: Illustrative order: 10 small refrigeration condensing units shipped without HFCs; FOB and freight values are illustrative under 8418 69 00 99, invoiced at £6,000 free on board, with £1,000 of freight and insurance to the UK. The customs value is £7,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £7,000, so it is £1,400. 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: check the compressor, fan motors, controller and nameplate against the approved specification; reconcile the refrigerant and shipping charge with the customs documents.

Cooling performance: test with a matched evaporator at the agreed operating conditions; record cooling output, power input, pressures and protective cut-outs.

Circuit and construction: review pressure and leak-test records; inspect brazed joints, capped connections, service valves, coil fins, fan guards and vibration mounts.

Arrival condition: inspect crates, mounting feet, pipework and electrical terminals for transit damage before installation; compare the received unit and documents with the inspection record.

What goes wrong

A package selected from compressor power alone can miss the cooling duty in warm ambient conditions. A substituted compressor or undersized condenser changes the performance behind the original test report. Bent fins, cracked brazed joints and loose mounting bolts can turn transit damage into commissioning failures. Require approval for component substitutions and preserve photographs of arrival damage.

Duty-free does not mean unrestricted. The reference guide identifies refrigerant bans affecting stationary refrigeration and certain centralised systems. Check the actual refrigerant and intended system before ordering, and have the broker confirm how the tariff controls apply. Documents for a similar model leave the delivered configuration unverified. Use testing and certification support to organise the evidence for the specified unit.
