Sourcing mechanical sauna timers from China
Mechanical sauna timers with a clock movement or synchronous motor attract 4% UK duty from China, with no trade remedy or suspension listed. Mains models need electrical safety evidence; specify whether the contacts switch the heater directly or operate a contactor. Cambridge China Bridge sources mechanical sauna timers.
4% duty on mechanical sauna time switches
Read from the UK Trade Tariff on 4 October 2026, heading 9107 covers time switches with clock or watch movement or synchronous motor. The supplied line, 9107 00 00 90, carries 4% duty for goods from China, with no anti-dumping or countervailing measure and no suspension listed. Only this relevant commodity line was supplied.
The tariff also attaches a control labelled DCMS Export Licence. Official guidance says there are no licensing requirements for importing objects of cultural interest into Great Britain. Ask your customs broker to confirm how the attached export-control entry should be handled for your shipment of new timers.
Confirm the commodity code using the mechanism description, wiring diagram and intended function. This guide concerns electrical time switches, rather than sand timers used to time sauna sessions. For the wider product family, see mechanical oven timer switches.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Mechanical sauna time switches with clock movement or synchronous motor | 9107 00 00 90 | 4% | None |
Specify the heater circuit and mounting position
State whether the timer switches heater power directly or operates a contactor coil. Specify the contact arrangement, rated voltage, load type, switching capacity, countdown range, delayed-start function if needed, and behaviour when the dial returns to its stop. Ask for a terminal diagram and a sample connected to the intended circuit.
Agree the shaft profile and length, panel cut-out, mounting depth, knob alignment and terminal access. State whether the mechanism sits in a heater housing or a separate control panel, and agree evidence for the temperature and moisture conditions at that position. Ask the supplier to identify any continuous-on position explicitly.
For mains timers, confirm the applicable requirements for electrical safety evidence, a declaration of conformity, relevant importer details and CE or UKCA marking for Great Britain with the relevant product-safety authority. Instructions must be in easily understandable English. Match the documents to the supplied model and installation arrangement; use testing and certification support to define the evidence needed.
Worked duty example
Illustrative example, not a quote: Illustrative order of 1,000 mechanical sauna timers under 9107 00 00 90, invoiced at £40,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £41,500. Duty at 4% is £1,660. Import VAT at 20% is charged on the customs value plus duty, £43,160, so it is £8,632. Import taxes total £10,292; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,660 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Timing: run sampled timers from different dial positions, compare elapsed time against a reference clock, and check that the contacts open at the end.
Switching: test with the agreed heater circuit or contactor coil, check contact operation and temperature rise, and investigate sticking contacts or failure to disconnect.
Fit: compare shafts, mounting holes, knobs and terminals with the approved drawing; check that panel fitting does not obstruct dial movement.
Documents: match model markings, load ratings, wiring instructions and conformity documents to the goods. Repeat functional checks on arrival using the agreed inspection plan.

What goes wrong
A timer can fit the panel yet have the wrong contact arrangement or insufficient switching capacity. A knob can indicate the end of a session while misaligned contacts remain closed. Include these failure modes in sample approval and inspection.
Do not accept an oven-timer sample as proof of suitability for the intended sauna mounting position. Agree the operating environment and test arrangement before ordering, and retain an approved sample showing the correct shaft, terminals and dial operation.

Frequently asked questions
What is the UK import duty on mechanical sauna timers from China?
The supplied tariff line 9107 00 00 90 carries 4% duty, with no trade remedy or suspension listed, for timers with a clock movement or synchronous motor.
Can the timer switch a sauna heater directly?
Only select it for direct switching after checking its rating against the actual heater circuit. A timer intended to operate a contactor coil may be unsuitable for switching heater power.
What documents should I request?
For mains models, request the declaration of conformity, matching electrical safety evidence, model and importer details, and English wiring and operating instructions.
What should I test before accepting delivery?
Check countdown operation, contact opening at the end, switching under the agreed load, shaft and panel fit, knob alignment and consistency with the approved sample.
