Sourcing graphing calculators from China

Zero duty on graphing calculators

Read from the UK Trade Tariff on 1 October 2026, heading 8470 covers calculating machines and certain pocket-size machines with calculating functions. For graphing calculators, the distinction is whether the device operates without an external power source. The table shows product variants sharing tariff lines, rather than separate codes for screen types.

The supplied tariff data records 0% duty for goods from China on both relevant lines, with no anti-dumping or countervailing duty, suspensions or attached import controls. Zero customs duty does not remove import VAT, normally 20%. See import duty and VAT.

Confirm the commodity code using the power arrangement, calculating functions and any printing device. Rechargeable does not mean externally powered if the calculator can operate independently. For wider calculator coverage, see scientific calculators.

Specify graphing functions and firmware

Agree the display type, graph plotting, equation solving, statistics, programming, symbolic algebra, memory, power source and supplied accessories. Define the angle settings and calculation precision needed by your customers. Record the firmware version on the approved sample and require approval before the factory changes it.

For school sales, check the current exam-board guidance against the exact functions and firmware. Specify how any exam mode disables restricted functions and how the user confirms it is active. Request English instructions explaining plotting, resetting, charging and memory clearing.

Confirm applicable battery and electrical waste obligations for calculators with the relevant authority. Electrical equipment producers must register annually. For equipment within the electromagnetic compatibility rules, CE or UKCA marking can be used for the Great Britain market. Under the hazardous-substance rules, individual products must show the importer’s name or trademark and contactable address on the product or packaging. Match the compliance documents to the supplied model through testing and certification.

Worked duty example

Illustrative example, not a quote: Illustrative order: 40 battery-powered graphing calculators; FOB and freight figures are illustrative, not a quotation under 8470 10 00 00, invoiced at £1,500 free on board, with £184 of freight and insurance to the UK. The customs value is £1,684. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £1,684, so it is £336.80. 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

Calculations: compare graph shapes, intersections, equation solutions and statistical results with agreed reference answers; test angle settings and rounding.

Keys and display: press every key on sampled units, check repeated presses, plot across the screen and look for missing pixels, uneven lighting or unreadable labels.

Power and memory: check charging, battery contacts, restart behaviour, saved programmes and memory clearing against the agreed specification.

Firmware and paperwork: compare the version with the approved sample, test any exam mode, and match model identification, importer details, marking and instructions to the documents. Use a written inspection brief.

What goes wrong

A sample can plot correctly while production firmware changes menus, calculation behaviour or exam-mode restrictions. A calculator can also return unexpected results because its angle setting differs from the test script. Retain the approved sample and repeat the same calculations on shipment samples and on arrival.

Keys can double-register, displays can lose pixels and battery contacts can interrupt power. Check whether saved work survives a normal restart and whether a deliberate reset clears it as specified. Record defects by model and firmware version before agreeing replacements or a repeat order.
