Sourcing hipot testers from China
Hipot testers within heading 9030 carry 0% UK import duty from China across the relevant lines. Confirm with the relevant authority whether mains-powered instruments fall within the Electrical Equipment (Safety) Regulations 2016. Match safety evidence and calibration to the exact model before buying. Cambridge China Bridge sources hipot testers.
Zero duty on relevant electrical test instruments
Read from the UK Trade Tariff on 17 October 2026, heading 9030 covers instruments for measuring or checking electrical quantities. For hipot testers, establish whether the equipment checks voltage, current or resistance, whether it has a recording device, and whether the shipment contains complete instruments or separately supplied parts.
All selected lines carry 0% duty for goods from China. The supplied tariff records show no anti-dumping or countervailing measures, suspensions or attached import controls for these lines. Import VAT is normally 20%; see import duty and VAT.
The table contains classification candidates, not interchangeable codes for every hipot tester. Give your broker the manual, measurement functions and recording details to confirm the commodity code. See the wider electrical instruments guide for the broader heading.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Voltage or current checking instruments without a recording device | 9030 33 70 00 | 0% | None |
| Voltage, current or resistance checking instruments with a recording device | 9030 39 00 00 | 0% | None |
| Resistance measuring instruments without a recording device, other | 9030 33 20 90 | 0% | None |
| Parts and accessories for electrical measuring or checking instruments | 9030 90 00 00 | 0% | None |
Specify the test output and operator protection
Specify alternating-current or direct-current withstand testing, output range, leakage-current measurement accuracy, trip settings, ramp and dwell behaviour, and any insulation-resistance function. Describe the intended load and fixture. Agree how results are stored, exported and matched to the item tested.
Specify an interlocked test enclosure, emergency stop, guarded connections and discharge behaviour where relevant to your setup. Ask for a demonstration using representative loads. Confirm with the relevant authority whether mains-powered instruments fall within the Electrical Equipment (Safety) Regulations 2016; for equipment within scope, importers must ensure instructions are in easily understandable English.
For Great Britain, importers must check the manufacturer's conformity assessment and provide their name and postal address on the equipment, or elsewhere where marking the equipment is not possible. Check electromagnetic compatibility applicability and hazardous-substance compliance, including any claimed exemption. Confirm any waste electrical equipment obligations with the relevant authority.
Worked duty example
Illustrative example, not a quote: A small distributor's batch of bench hipot testers without recording devices, illustrative under 9030 33 70 00, invoiced at £26,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £27,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £27,200, so it is £5,440. 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
Documents: match the model, hardware revision and supplied leads to the safety reports; check English instructions, importer identification and calibration certificates matched to serial numbers.
Output and measurement: have a competent test specialist compare voltage and leakage-current readings with calibrated reference equipment across the agreed ranges and representative loads.
Protection: demonstrate interlock interruption, emergency stop, trip behaviour and discharge after normal completion and aborted tests, using the agreed guarded setup.
Recording and delivery: check stored results against actual test outcomes, confirm export and serial-number matching, and inspect connectors, leads and transit damage during inspection.

What goes wrong
Watch for a tester that reaches its advertised voltage without a load but cannot maintain it on the buyer's fixture. Incorrect leakage-current readings or trip settings can give misleading pass results. Test with agreed reference loads rather than accepting a display demonstration.
Treat defeated interlocks, unverified discharge behaviour, substituted leads and reports for a different model as reasons to hold acceptance. A calibration certificate alone does not establish operator protection. Resolve discrepancies with the factory before releasing the batch.

Frequently asked questions
What is the UK import duty on hipot testers from China?
The relevant heading 9030 lines carry 0% duty in the supplied tariff records, with no listed anti-dumping or countervailing measures. Confirm the code for the exact instrument.
Which commodity code applies to a hipot tester?
Classification depends on measurement functions and whether there is a recording device. Supply the manual and technical description to your broker; do not classify from the product name alone.
Should I ask for a calibration certificate?
Ask for a certificate matched to each serial number, traceable to national standards for professional use. Agree checks of output voltage and leakage-current measurement.
What should I check before accepting a hipot tester?
Check output under representative load, trip settings, interlocks, emergency stop, discharge behaviour, leads and result recording. Have a competent specialist conduct the guarded tests.
