Sourcing VRF air conditioning from China

UK duty and refrigerant controls for VRF systems

Read from the UK Trade Tariff on 30 September 2026, the selected lines of heading 8415 carried 2% duty on goods from China, with no listed anti-dumping or countervailing duty and no suspension. The heading covers air-conditioning machines and their parts. For VRF purchases, the relevant distinction is between a complete split system, other reversible equipment, separately supplied units and parts.

The UK Trade Tariff attaches an import control on fluorinated greenhouse gases and an ozone-depleting-substance restriction to the selected lines. New VRF equipment must not use ozone-depleting substances. For pre-charged HFC equipment, check the annual quota position and F-gas declaration before shipment. Where quota authorisations or delegations are required, equipment cannot be imported into Great Britain without enough coverage. Ask your customs broker to confirm the applicable declarations and supporting documents.

Confirm the commodity code from the refrigerant, reversing function, equipment specification and how the shipment is presented. The table gives candidate lines, rather than a classification for every VRF configuration. For the wider heading, see rooftop packaged air conditioners.

Specify the matched VRF system

Specify the outdoor modules, matched indoor-unit schedule, room loads, cooling and heating duties, heat-pump or heat-recovery operation, and branch joints or selector boxes. Record permitted pipe lengths, height differences, connection ratios, additional refrigerant calculations, power supply and control interfaces. Have the intended installer review the manufacturer's selection and piping drawings before approving the order.

Ask for performance and electrical safety reports for the exact equipment combination, its UKCA or CE declaration of conformity, wiring diagrams and spare control-board list. Electrical equipment must have clear English instructions. For applicable ecodesign rules, the declaration of conformity must be supported by technical documentation. Include installation, addressing, commissioning and fault-diagnosis instructions in the document review.

For imports into Great Britain, confirm with the Environment Agency which annual import thresholds, registration and quota authorisation requirements apply to the imported HFCs, and whether the pre-charged equipment needs an F-gas declaration of conformity. Calculate the annual total from each model's refrigerant and factory charge, rather than assessing each shipment separately.

Worked duty example

Illustrative example, not a quote: Illustrative order: one reversible VRF system for small business premises under 8415 81 00 91, 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 2% is £184. Import VAT at 20% is charged on the customs value plus duty, £9,384, so it is £1,876.80. Import taxes total £2,060.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £184 of duty. The import duty and VAT guide explains each step.

Inspection checklist

System matching: check outdoor and indoor model references, controllers, branch components and firmware against the approved selection. Confirm every item is identified on the packing list.

Refrigerant and circuit: check nameplate refrigerant, factory charge and carbon dioxide equivalent against the documents. Review factory leak-test records and inspect service valves, capped connections and pipework for damage.

Function and safety: review electrical test records and witness an assembled sample operating in cooling and heating. Check indoor-unit addressing, controller communication, condensate drainage and any specified heat-recovery function.

Arrival and documents: inspect coils, cabinet feet, lifting damage and packaging moisture before installation. Reconcile serial numbers, manuals and accessories with the shipment records. Plan these checks through quality inspection.

What goes wrong

A compatible-looking indoor unit can have the wrong control protocol, while substituted selector boxes or branch joints can make the delivered system differ from the approved design. Missing piping limits or additional-charge instructions leave the installer unable to confirm the proposed layout. Check the matched equipment schedule and complete document set before shipment.

Leaks, damaged coil fins, inadequate drainage and control-board faults can emerge during commissioning. Agree who provides diagnostic support, replacement boards and commissioning records before ordering. Arrange a qualified F-gas technician for installation, and give them the system selection and refrigerant information before the equipment arrives.
