Sourcing thermal fogging machines from China
Relevant thermal fogging machine and parts lines carry 0% UK duty from China, with no trade remedy recorded. New machinery sold in Great Britain must have CE or UKCA marking, a declaration of conformity and English instructions. Check the intended formulation and operating method.

Zero duty, with classification by function
Read from the UK Trade Tariff on 30 September 2026, the selected lines under heading 8424 carried 0% duty for goods from China, with no anti-dumping or countervailing duty or suspension recorded. The heading covers mechanical appliances for projecting, dispersing or spraying liquids or powders, alongside other equipment. These rows are classification candidates for thermal foggers and their parts, rather than interchangeable codes.
The supplied tariff attaches fluorinated greenhouse gas import controls to the other-appliance and parts lines, an ozone-depleting-substance free-circulation restriction to the parts line, and a torture-and-repression export restriction to the other-appliance line. Confirm the applicable requirements with your customs broker using the machine specification and contents before shipment; the supplied control notes do not establish the declaration requirements for an ordinary thermal fogger.
Confirm the commodity code from the operating principle, intended agricultural or other use, portability and whether the shipment contains complete machines or separate parts. For the wider heading, see pressure washers and sprayers.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Portable agricultural or horticultural sprayers | 8424 41 00 00 | 0% | None |
| Other agricultural or horticultural dispersing appliances | 8424 82 90 00 | 0% | None |
| Other dispersing appliances, including foggers where classified here | 8424 89 70 00 | 0% | None |
| Other appliance parts, including fogger parts where classified here | 8424 90 80 80 | 0% | None |
Specify the heating system and formulation
Specify a thermal fogger explicitly, including the heating principle, fuel, ignition system, solution tank material, seals, adjustable liquid delivery and intended formulation. Ask for evidence supporting output and droplet claims under stated operating conditions. Agree the starting, shutdown, cooling and cleaning procedures, and identify replaceable filters, seals and ignition components.
New machinery placed on the Great Britain market must be CE or UKCA marked, accompanied by a declaration of conformity and supplied with English instructions. Match the documents to the ordered model. For biocide use, read and understand the product label and follow its instructions carefully; assess the proposed thermal application against those instructions before choosing the machine.
Worked duty example
Illustrative example, not a quote: Illustrative order: 40 thermal fogging machines, subject to classification confirmation under 8424 89 70 00, invoiced at £28,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £32,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £32,000, so it is £6,400. 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
Fuel and solution circuits: inspect tanks, caps, hoses, seals and joints for damage or leakage, and compare materials with the agreed specification.
Starting and shutdown: have a competent operator demonstrate ignition, stable operation, liquid delivery and shutdown under the agreed safe test procedure.
Heat and handling: inspect hot-surface guards, handles, mounting points and transport damage; check that controls remain accessible during operation.
Documents and spares: match model identification, conformity marking, declaration and English instructions; check the supplied seals, filters and ignition spares at inspection.

What goes wrong
A visible fog plume alone does not establish useful delivery or suitability for the intended liquid. Look for unstable ignition, leaking connections, blocked delivery passages, inconsistent flow and seals that deteriorate with the proposed formulation. Record operating conditions when comparing the approved sample with production machines.
A generic manual can leave operators guessing about shutdown, cleaning or compatible liquids. Resolve these gaps before shipment and avoid accepting a supplier's blanket claim that the machine works with every disinfectant or pesticide.

Frequently asked questions
What is the UK import duty on thermal fogging machines from China?
The selected machine and parts lines carry 0% duty from China, with no trade remedy or suspension recorded in the supplied tariff facts. Confirm the exact code for the model and its intended use.
Do thermal fogging machines need CE or UKCA marking?
New machinery placed on the Great Britain market must have CE or UKCA marking, a declaration of conformity and English instructions. Check that the documents identify the supplied model.
Can I use any disinfectant in a thermal fogger?
Check formulation compatibility with the machine supplier. For a biocidal product, read and understand its label and follow the instructions carefully; assess whether they support the proposed thermal application.
How should I test a thermal fogging machine before shipment?
Agree a safe demonstration covering ignition, stable delivery, leaks, shutdown and cleaning. Compare production samples with the approved specification and record the liquid and operating conditions.
