Sourcing power quality analysers from China
Power quality analysers from China under heading 9030 carry 0% UK duty across the relevant lines. Confirm with the relevant authority which electrical equipment safety rules apply to mains-powered instruments; verify the measurement category, probe ratings and supporting test reports before ordering. Cambridge China Bridge sources power quality analysers.
Zero duty on relevant analyser lines
Read from the UK Trade Tariff on 17 October 2026, the relevant heading 9030 lines carry 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duties, suspensions or attached import controls for these lines.
Heading 9030 covers instruments for measuring or checking electrical quantities, excluding supply meters. For power quality analysers, distinguish voltage, current or power measurement with recording from other electrical measurement functions. The table gives candidate lines, rather than a classification for every analyser or separately supplied probe.
Confirm the commodity code using the manual, measurement functions and recording capability. See the oscilloscopes and multimeters guide for the wider heading.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Voltage, current or power analysers with recording | 9030 39 00 00 | 0% | None |
| Other voltage, current or power instruments without recording | 9030 33 70 00 | 0% | None |
| Other electrical measuring apparatus with recording | 9030 84 00 00 | 0% | None |
| Parts and accessories for electrical measuring instruments | 9030 90 00 00 | 0% | None |
Specify recording, probes and measurement accuracy
Define the supply configurations, voltage and current ranges, frequency range and accuracy for each measured quantity. Specify harmonic analysis, voltage dips and swells, transient capture, event triggers and waveform recording separately. Agree recording duration, memory behaviour when full, timestamp handling and the report format your technicians need.
List the current probes supplied with each analyser, their ranges, connector compatibility and scaling settings. Ask for calibration evidence covering the analyser and its supplied probes together. For professional use, request certificates traceable to national standards and matched to serial numbers.
Confirm with the relevant authority which electrical equipment safety rules apply to mains-powered instruments. Check measurement category and voltage ratings against the exact model's safety report, including leads and probes. Ask the relevant authorities to confirm applicable waste electrical equipment obligations and whether wireless models fall within radio equipment rules. The manufacturer must supply relevant English instructions under electromagnetic compatibility rules.
Worked duty example
Illustrative example, not a quote: An illustrative batch of portable power quality analysers with current probes under 9030 39 00 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
Measurement chain: compare voltage, current, power and harmonic readings with a calibrated reference source, using the supplied probes and their agreed scaling settings.
Recording: inject agreed test events, check trigger operation and timestamps, interrupt power during logging, and confirm that saved waveforms and reports can be exported and reopened.
Safety and identity: compare input protection, lead insulation, connectors and category markings with the approved sample and reports. Under hazardous-substance rules, individual products must show the importer's name or trademark and a contactable address on the product or packaging.
Delivery set: reconcile probes, leads, chargers, cases and calibration certificates against the packing list. Check English menus and manuals during inspection.

What goes wrong
A correct voltage reading does not prove that the complete analyser measures power correctly. Reversed probes, wrong scaling settings or mismatched phase connections can produce misleading power and power-factor results. Test the complete supplied measurement chain rather than accepting a demonstration of the display.
An analyser may show a disturbance live but fail to retain the waveform or export a usable report. Agree sample event files and report outputs before ordering, then repeat the same tests on shipment samples. Treat substituted probes or firmware as changes requiring another check.

Frequently asked questions
What is the UK import duty on power quality analysers from China?
The relevant heading 9030 lines carry 0% duty for goods from China in the supplied tariff record, with no anti-dumping or countervailing duties. Import VAT is normally 20%.
Which commodity code covers a recording power quality analyser?
9030 39 00 00 is a candidate for voltage, current or power instruments with recording. Confirm the actual functions; other electrical measuring apparatus may fall under a different line.
Should calibration include the current probes?
Ask for evidence covering the analyser with its supplied probes and scaling settings. Match certificates to serial numbers and request traceability to national standards for professional use.
What should I test before shipment?
Check readings with the supplied probes, inject agreed disturbances, verify event timestamps and waveform retention, and reopen exported reports. Compare safety markings and accessories with the approved sample.
