Sourcing irrigation time switches from China
Electromechanical irrigation timers with a clock movement or synchronous motor carry 4% UK duty from China, with no additional trade remedy shown. For mains-powered models, confirm the applicable electrical safety evidence and CE or UKCA marking requirements for Great Britain with the relevant product-safety authority. Cambridge China Bridge sources electromechanical irrigation timers.
UK duty on electromechanical irrigation timers
Read from the UK Trade Tariff on 4 October 2026, heading 9107 covers time switches with a clock or watch movement or synchronous motor. The supplied facts contain a single relevant commodity line, 9107 00 00 90, carrying 4% duty for goods from China. The table shows product variants sharing that line. No anti-dumping or countervailing duty, or suspension, is recorded.
The tariff facts also attach a DCMS export-licence annotation. Official guidance states that cultural objects have no import licensing requirements in Great Britain. Ask your customs broker to confirm how the annotation applies to a new timer shipment from China.
Confirm the timing mechanism, switching function and commodity code before ordering. Digital controllers without a clock movement or synchronous motor may fall elsewhere. For the wider time-switch family, see synchronous-motor pool-pump time switches.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Synchronous-motor irrigation timers for control panels | 9107 00 00 90 | 4% | None |
Specify the movement, irrigation load and enclosure
Specify the timing mechanism, supply voltage and frequency, dial cycle, shortest switching interval, switching contacts and manual override. State whether the timer switches a pump directly, operates a contactor or controls irrigation valves. Agree the appropriate inductive-load rating rather than relying on a resistive-load rating. Define the mounting arrangement, terminal access and behaviour after a power interruption.
For exposed installations, agree the enclosure, cable entries, seals and evidence supporting the claimed weather protection. For mains-powered timers, confirm with the relevant product-safety authority the applicable requirements for electrical safety evidence, a declaration of conformity, CE or UKCA marking for Great Britain and importer identification. Instructions must be clear, legible and in easily understandable English.
Check whether electromagnetic compatibility rules apply to the finished design. Ask for hazardous-substance compliance evidence: supplier assurances do not replace the manufacturer's assessment. Plan electrical-waste producer obligations, including annual registration.
Worked duty example
Illustrative example, not a quote: Illustrative order: 1,000 electromechanical irrigation timers under 9107 00 00 90, invoiced at £25,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £26,500. Duty at 4% is £1,060. Import VAT at 20% is charged on the customs value plus duty, £27,560, so it is £5,512. Import taxes total £6,572; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,060 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Timing: run sampled timers against a reference clock, check every programmed switching event and confirm that dial segments remain engaged.
Load switching: test with the agreed pump, contactor or valve load; check contact operation, overheating, manual override and restart after a power interruption.
Enclosure: check lid seals, cable-entry seals, terminal covers and mounting points; verify the agreed weather-protection evidence.
Documents: match the model, ratings, declaration, test reports, markings and English instructions to the supplied goods. Use an agreed inspection checklist.

What goes wrong
A timer can keep time correctly yet fail when a pump starts. An unsuitable contact rating can cause overheating or welded contacts, leaving irrigation running. Other failure modes include a movement matched to the wrong supply frequency, loose dial segments, unclear override positions and loss of the watering schedule after an interruption.
Water can enter through cable glands or a poorly seated lid even when the enclosure looks suitable. Approve a wired sample with the intended load and installation arrangement, then compare incoming stock against that sample and the agreed specification.

Frequently asked questions
What is the UK import duty on electromechanical irrigation timers from China?
The supplied tariff facts show 4% under 9107 00 00 90, with no anti-dumping or countervailing duty and no suspension recorded.
Can the timer switch an irrigation pump directly?
Only select it for direct switching when its documented rating suits the pump load. Otherwise specify a suitable contactor arrangement and test the timer with it.
Do mains-powered irrigation timers need CE or UKCA marking?
For mains-powered timers intended for Great Britain, confirm the applicable CE or UKCA marking, declaration of conformity, electrical safety evidence and importer identification requirements with the relevant product-safety authority.
Are digital irrigation controllers covered by this guide?
This guide covers timers with a clock movement or synchronous motor. A digital controller without either mechanism may need a different commodity code.
