Sourcing gas-fired curing ovens from China

Zero duty, with classification to confirm

Read from the UK Trade Tariff on 2 October 2026, heading 8417 covers non-electric industrial or laboratory furnaces and ovens, including incinerators. Gas-fired powder-coating curing ovens are candidates for 8417 80 70 00, described as other ovens and furnaces. The table repeats this line for different loading arrangements; these are buying options rather than separate tariff subdivisions.

All supplied lines carry 0% duty for goods from China. The supplied tariff data lists no anti-dumping or countervailing duties, suspensions or attached import controls. Dedicated oven parts are candidates for 8417 90 00 00, but separately supplied burners and other components need their own classification review.

Give your customs broker the heating method, process description, drawings and shipment contents to confirm the commodity code. Explain that the process cures a coating rather than heat-treating the underlying metal. See the wider industrial furnaces and ovens guide for the heading's other products.

Specify the loaded cure cycle and gas system

Specify the powder supplier's cure schedule, workpiece materials and thicknesses, largest part, loading arrangement and usable chamber dimensions. Agree temperature uniformity under a representative load and measure workpiece temperature as well as oven air temperature. State whether the oven is batch or conveyor operated, and whether combustion gases contact the workpieces.

Define the site gas type and supply conditions, burner and gas train, circulation fans, exhaust connections, insulation, door seals and control recording. Agree responsibility for unloading, assembly, installation and commissioning with a UK engineer. Include access for cleaning and replacement of fans, sensors and burner components.

For sale in Great Britain, confirm with the relevant authority how the Supply of Machinery (Safety) Regulations 2008 apply to the oven, including the declaration of conformity, conformity marking and English instructions. CE marking continues to be recognised in Great Britain. HSE states that hazardous substances in coating powders must be controlled under the Control of Substances Hazardous to Health Regulations; plan the oven within the coating line's exposure controls.

Worked duty example

Illustrative example, not a quote: One gas-fired conveyor powder-coating curing oven, illustrative only under 8417 80 70 00, invoiced at £72,000 free on board, with £6,500 of freight and insurance to the UK. The customs value is £78,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £78,500, so it is £15,700. 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

Cure performance: witness a representative loaded run before shipment, record workpiece temperature histories, and compare coating cure and finish with the agreed acceptance method.

Burner controls: have a competent engineer witness flame supervision, purge, safety shut-off, fan interlocks, over-temperature protection and emergency-stop tests.

Arrival condition: inspect insulation panels, casing joints, door seals, duct connections and trolley or conveyor alignment for transport damage before commissioning.

Documents: match the oven identity to its declaration, marking and English instructions; check wiring drawings, gas train diagrams, test records and the spares list. Use the quality inspection guide to plan checks.

What goes wrong

An empty oven reaches its setpoint while heavy workpieces remain too cold to cure. Poor airflow creates uneven finish, and excessive airflow can disturb uncured powder. Leaking doors and weak insulation increase heat loss. A burner configured for different site gas conditions can also delay commissioning.

Agree a loaded acceptance test using your powder and representative workpieces. Review the gas system and installation interfaces before manufacture, and repeat the agreed checks after assembly on site. Ask for evidence of comparable coating-oven builds through factory verification.
