Sourcing fire-tube steam boilers from China
Fire-tube steam boilers from China carry 0% UK duty, with no anti-dumping or countervailing duty recorded. Pressure equipment conformity assessment applies, and qualifying systems need a written scheme of examination and examination before use. Cambridge China Bridge sources fire-tube steam boilers.
Zero duty on fire-tube steam boilers
Heading 8402 covers steam or other vapour generating boilers, superheated water boilers and parts. Fire-tube steam boilers fall under 8402 19 10 00. The table includes parts and neighbouring boiler lines for classification comparison; those neighbouring lines are not alternative codes for a fire-tube steam boiler.
Read from the UK Trade Tariff on 24 October 2026, fire-tube steam boilers and the other listed lines carried 0% duty for goods from China. The supplied tariff data records no anti-dumping or countervailing duty, suspension or attached import control. Product safety and operating requirements still apply.
Confirm the commodity code from the boiler construction, working fluid and whether the shipment contains a complete boiler or parts. For another product family within this heading, see water-tube steam boilers.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Fire-tube steam boilers | 8402 19 10 00 | 0% | None |
| Steam boiler parts | 8402 90 00 00 | 0% | None |
| Other vapour generating boilers, for classification comparison | 8402 19 90 00 | 0% | None |
| Superheated water boilers, for classification comparison | 8402 20 00 00 | 0% | None |
Specify the shell, steam duty and burner
Specify steam output, operating pressure, fuel, feedwater conditions and the expected operating cycle. Agree shell and tube materials, tubeplate joints, access for cleaning, burner and feed pump scope, safety valves, low-water protection and the electrical supply. Ask for drawings showing connections, lifting points and maintenance clearance.
Fire-tube shell boilers commonly use BS EN 12953. Under the Pressure Equipment (Safety) Regulations 2016, agree the equipment category, conformity assessment route, UKCA or CE marking and declaration of conformity before fabrication. The importer must check the manufacturer's conformity assessment and provide importer identification.
For a combustion plant in England and Wales, confirm with the relevant environmental authority whether medium combustion plant permitting requirements apply. Confirm the site's applicable permit, exemptions and emission limits before agreeing the burner specification.
Worked duty example
Illustrative example, not a quote: Illustrative order: one fire-tube steam boiler with burner and controls under 8402 19 10 00, invoiced at £60,000 free on board, with £5,000 of freight and insurance to the UK. The customs value is £65,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £65,000, so it is £13,000. 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 documents: match the serial number, design pressure and supplied assembly to the drawings and conformity documents. Instructions must be in clear, legible and easily understandable English.
Pressure boundary: witness the factory hydrostatic test, review weld inspection records and trace shell plates, tubes and tubeplates to their material certificates. Check tube-to-tubeplate joints for leakage.
Controls and protection: witness the agreed checks of low-water cut-outs, burner interlocks, feed controls and safety valves. Match the panel and wiring to the specified supply.
Arrival condition: inspect cladding, insulation, supports, connections and loose accessories before accepting delivery. Record transport damage and compare the packing list with the supplied assembly. Plan quality inspection before dispatch.

What goes wrong
Documents may describe a different pressure rating or omit the burner and controls supplied with the shell. Material traceability can be incomplete, welds can contain porosity, and tubeplate joints can leak after firing. Make document matching and witnessed tests part of the purchase specification.
Transport can damage insulation and connections, while unsuitable controls can delay commissioning. A factory pressure test does not replace the user's examination arrangements: before using qualifying pressure equipment, a written scheme of examination must be in place and an examination undertaken.

Frequently asked questions
What is the UK import duty on fire-tube steam boilers from China?
The supplied tariff reading gives 0% for 8402 19 10 00, with no anti-dumping or countervailing duty, suspension or attached import control recorded.
Does a Chinese fire-tube boiler need UKCA or CE marking?
Pressure equipment conformity assessment applies. Agree the category and the appropriate UKCA or CE route, then match the declaration of conformity to the boiler and supplied assembly.
What should I ask the factory to test?
Ask to witness the hydrostatic test and agreed protection checks. Review weld inspection records, material certificates, tubeplate joints, low-water cut-outs and burner interlocks.
Can I operate the boiler straight after delivery?
Before using qualifying pressure equipment, a written scheme of examination must be in place and an examination undertaken. Arrange this alongside installation and commissioning.
