Sourcing vacuum brazing furnaces from China
Electric vacuum brazing furnaces from China under heading 8514 carry 0% UK duty across the relevant lines. Machinery supplied in Great Britain needs UKCA or CE marking, a declaration of conformity and English instructions. Specify the loaded brazing cycle and vacuum performance. Cambridge China Bridge sources electric vacuum brazing furnaces.
UK duty and furnace classification
Read from the UK Trade Tariff on 1 October 2026, heading 8514 covers industrial or laboratory electric furnaces and ovens, induction or dielectric heat-treatment equipment, and parts. Electric vacuum brazing furnaces belong within this family; the heating method determines the relevant line.
The supplied tariff data shows 0% duty for goods from China on every listed line, with no anti-dumping or countervailing duty, suspensions or attached import controls. Other resistance-heated furnaces fall under 8514 19 80 00. The table includes alternative furnace designs and separately supplied parts, rather than interchangeable codes for the same machine.
Confirm the heating method, intended use and completeness of the shipment using the commodity code guide. A vacuum chamber alone does not identify the heating method. See the wider vacuum heat-treatment furnace guide for related equipment.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Resistance-heated vacuum brazing furnaces | 8514 19 80 00 | 0% | None |
| Induction furnaces, where the brazing furnace uses induction heating | 8514 20 10 00 | 0% | None |
| Other electric furnaces, where the design falls outside the named heating types | 8514 39 90 00 | 0% | None |
| Other furnace parts, subject to classification of the supplied component | 8514 90 70 00 | 0% | None |
Specify the brazing load and vacuum cycle
Give the factory the parent metals, brazing alloy, joint geometry, fixture arrangement and representative load. Agree usable chamber space, load weight, working temperature, uniformity, heating and cooling profiles, and how the finished joints will be assessed. Specify hot-zone materials compatible with your process and the required cycle records.
Define working vacuum during the loaded cycle, pump-down behaviour, leak testing, gauges, pump configuration and backfill gas. Agree cooling-water needs, site electricity supply, pump exhaust arrangements, spare seals and heating elements. Ask for a witnessed trial using your parts and fixtures, rather than accepting an empty-chamber demonstration.
For machinery supplied in Great Britain, check UKCA or CE marking, the declaration of conformity and English instructions, alongside electromagnetic compatibility evidence. The responsible person must ensure the technical file is compiled and available on request. Arrange a testing and certification review before shipment.
Worked duty example
Illustrative example, not a quote: Illustrative order of two electric resistance-heated vacuum brazing furnaces under 8514 19 80 00, invoiced at £64,000 free on board, with £5,500 of freight and insurance to the UK. The customs value is £69,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £69,500, so it is £13,900. 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
Loaded trial: compare joint quality, temperature distribution and cycle records against the agreed acceptance criteria using representative parts and fixtures.
Vacuum system: check pump-down and leak-test records, gauge identification, valve operation and the vacuum maintained during brazing.
Safety and documents: check door interlocks, over-temperature protection, cooling-loss response, emergency stop, earthing, marking, declaration and English manual.
Arrival: inspect chamber seals, feedthroughs, gauges, hot-zone supports and pipework for transit damage; reconcile supplied pumps, fixtures and spares with the packing list before commissioning.

What goes wrong
An empty furnace can meet a vacuum target while the production load releases gas and disrupts the brazing cycle. Uneven heating, contaminated fixtures or unsuitable hot-zone materials can leave joints incompletely filled or discoloured. Agree acceptance around the loaded process and finished joints.
Transit can disturb seals, feedthroughs and hot-zone supports. Missing cycle records or unavailable pump and seal spares make fault finding harder. Record factory results and repeat the agreed checks after installation; use the quality inspection guide to define the inspection brief.

Frequently asked questions
What is the UK import duty on vacuum brazing furnaces from China?
The supplied tariff data shows 0% across the relevant heading 8514 lines, with no anti-dumping or countervailing duty. Other resistance-heated furnaces fall under 8514 19 80 00.
Does a vacuum brazing furnace need CE or UKCA marking?
For machinery supplied in Great Britain, check UKCA or CE marking, a declaration of conformity and English instructions. Check that the documents identify the furnace supplied.
What should a factory acceptance test include?
Use representative parts and fixtures. Check loaded temperature distribution, vacuum during brazing, cycle records, finished joint quality and safety interlocks against the agreed specification.
What should I check when the furnace arrives?
Inspect seals, gauges, feedthroughs, pipework and hot-zone supports. Check the packing list and documents, then repeat the agreed vacuum and loaded-cycle checks during commissioning.
