Sourcing Nixie display tubes from China
Nixie display tubes from China within heading 8540 carry a flat 0% UK duty, with no trade remedies in the supplied tariff data. Confirm with the relevant authority how restricted-substance rules apply to the tube materials and finished electrical product. Specify the pin layout and test every character.

0% duty on Nixie display tubes
Read from the UK Trade Tariff on 2 October 2026, heading 8540 covers thermionic, cold cathode and photocathode valves and tubes. For bare cold-cathode Nixie display tubes, start the classification check with 8540 89 00 99, the residual other-tubes line. The table shows product variants sharing that code, plus the other tube-parts line.
Every line in the supplied heading data carries 0% duty for goods from China. The data records no anti-dumping or countervailing duty, suspensions or attached import controls. This tariff position does not establish finished-product compliance. Import VAT is separate; see UK import duty and VAT.
Confirm the commodity code using the tube datasheet, photographs and supply condition. Have complete clocks and assembled display products checked separately. For the wider display-tube family, see vacuum-fluorescent display tubes.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Side-view Nixie numeral display tubes | 8540 89 00 99 | 0% | None |
| Parts of Nixie display tubes, subject to classification | 8540 99 00 90 | 0% | None |
Specify the characters, pin layout and drive conditions
Specify the exact tube type, character shapes and order, viewing direction, glass dimensions, mounting arrangement and pin or flying-lead layout. Agree ignition and operating voltages, cathode current, current limiting and the intended drive method. Approve samples in your actual driver circuit, with photographs of each illuminated character.
State whether you accept newly manufactured tubes, unused old stock or used tubes. Request the actual manufacturer, manufacturing country and batch identification. Agree brightness matching, a burn-in procedure and individual protective packing. Ask for records linking the supplied batch to the character tests.
Confirm with the relevant authority how restricted-substance rules apply to components used in UK electrical products and to the finished product. Request material evidence and the exact exemption relied on, if any. Great Britain operates its own exemptions system. Ask specifically about mercury content; take unresolved mercury-control questions to the Environment Agency before ordering. Arrange testing and certification around the actual tube and finished application.
Worked duty example
Illustrative example, not a quote: 300 Nixie display tubes for a clock-making business, illustrative only under 8540 89 00 99, invoiced at £12,000 free on board, with £600 of freight and insurance to the UK. The customs value is £12,600. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £12,600, so it is £2,520. 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
Identity: compare tube markings, character shapes, viewing direction and pin assignments with the approved sample and datasheet.
Display: illuminate every character at the agreed drive conditions; check complete glow coverage, unwanted glow, flicker and brightness differences.
Glass and connections: inspect envelopes and seals for cracks, internal deposits, bent pins, corrosion and damaged flying leads.
Packing and records: check individual cushioning and separation, then match batch labels and test records to the delivered goods. Use the quality inspection guide to define the inspection brief.

What goes wrong
A tube can light during a demonstration yet leave part of a character dark in your circuit. Mixed batches can differ in brightness or character shape. A similar-looking replacement can have a different pin layout or require different drive conditions. Test the actual supplied type rather than accepting a photograph of another model.
Used or relabelled stock, corroded connections and transit breakage can undermine an otherwise acceptable sample. Specify stock condition, retain the approved sample and agree how failed tubes will be recorded and replaced. Electrical testing alone does not establish restricted-substance compliance.

Frequently asked questions
What is the UK import duty on Nixie tubes from China?
The supplied tariff data shows 0% duty on every heading 8540 line, including 8540 89 00 99, with no anti-dumping or countervailing duty. Import VAT is separate.
Which commodity code should I use for Nixie tubes?
Start with 8540 89 00 99 for bare cold-cathode Nixie tubes and confirm against the datasheet. Complete clocks and assembled displays need their own classification check.
How do I check Nixie tubes before accepting delivery?
Illuminate every character in the agreed test circuit. Check glow coverage, brightness, unwanted glow, pin layout, glass seals and connections against the approved sample.
Can I accept unused old-stock Nixie tubes?
Specify that condition explicitly. Ask for manufacturer and batch details, check storage damage and character performance, and obtain material evidence rather than assuming old stock is compliant.
