Sourcing calculators and cash registers from China

Zero duty

Read from the UK Trade Tariff on 25 September 2026, electronic calculators that work without an external power source, other electronic calculators with or without a printing device, other calculating machines, cash registers and other machines incorporating a calculating device carried 0% duty on goods from China, with no anti-dumping measure.

Point-of-sale terminals built on a computer are usually classified as computers; confirm the commodity code.

Batteries and WEEE

Calculators with button cells fall under the Batteries and Accumulators (Placing on the Market) Regulations 2008, and all are electrical equipment with WEEE obligations. Battery compartments on children's calculators should need a tool to open.

Mains-powered cash registers need electrical safety and EMC evidence with UKCA or CE marking.

Schools and retail

Scientific and graphic calculators for UK schools must match the functions the exam boards allow, so check the current exam guidance before choosing a model. Cash registers for UK retail need a pound sign, VAT rate setting and English receipts. For enclosures, see our cash register housings sourcing guide. For abacuses, see our abacus sourcing guide.

Worked duty example

For a made-up shipment of 30,000 solar pocket calculators under 8470 10 00 00, add the £1,500 of freight and insurance to the £21,000 free-on-board price and customs sees £22,500. Duty on calculators is zero, leaving import VAT of £4,500, 20% of the customs value. For a VAT-registered buyer that is a cash-flow cost rather than a lasting one. The duty and VAT guide walks through the calculation.

Inspection checklist

Electrical evidence: mains-powered cash registers and printing calculators covered by test reports for the exact model to BS EN IEC 62368-1 for safety and BS EN 55032 and BS EN 55035 for EMC, the adapter checked for the UK plug, fuse and rating, and lithium coin cells backed by a BS EN 60086-4 safety report and a UN 38.3 summary.

Function and durability: every key pressed on sampled units against a written test script, a key-life cycle test on a few units to the number of presses agreed in the specification, solar models run with the battery removed under ordinary room lighting, and scientific models checked against a table of known results.

Receipts and children's models: thermal paper rolls supplied with cash registers checked against the bisphenol A limit in UK REACH Annex XVII entry 66, receipts printed with the pound sign, VAT rates and English text, battery compartments on children's calculators checked to need a tool to open, and cartons sampled to ISO 2859-1.

What goes wrong

Calculators and cash registers fail at the keys, the display and the firmware. Keys double-press or stop registering, solar cells that are too small leave the calculator dead in normal room light, and LCDs show missing segments. Scientific models can calculate some functions wrongly or allow functions that exams forbid, and cash registers arrive with firmware that cannot set UK VAT rates or print a pound sign.

Run a key and function test script on samples, check the display in low light and with the battery removed on solar models, check scientific functions against known answers, set VAT rates and print receipts on cash registers, and check battery compartments on children's models. Keep samples of each firmware version for future checks.

Inspection

At inspection, test every key and function against a script, check the display, solar cell and battery life, and print receipts on cash registers.
