Sourcing NAS appliances from China

Duty on network-attached storage appliances

Heading 8471 covers automatic data-processing machines and their units, including processing and storage units. The rows identify relevant classification candidates and separately supplied drives. A complete network-attached storage appliance should not automatically use the code for its installed hard disk drives.

Read from the UK Trade Tariff on 30 September 2026, all supplied lines carried 0% duty for goods from China. The supplied facts list no anti-dumping or countervailing duties, suspensions or attached import controls. Standard import VAT is 20%; zero customs duty does not remove VAT.

Confirm the appliance's principal function, hardware configuration and presentation with your customs broker using finding your commodity code. For the wider computing heading, see rack servers. For thin clients, see our thin client sourcing guide.

Specify the storage platform and supported firmware

State whether appliances are diskless or populated. Fix the processor, memory, drive bays, compatible drive models, network interfaces, usable capacity, supported file-sharing protocols and recovery behaviour. Agree firmware ownership, administrator access, update delivery, replacement power supplies and spare drive trays.

For Great Britain, electrical safety conformity assessment is required for equipment within scope, and electromagnetic compatibility rules permit CE or UKCA marking. Importers must be able to evidence compliance with hazardous-substance restrictions. Ask a testing and certification adviser to review the exact appliance and power supply, including the scope of ecodesign requirements.

Consumer network-connectable products fall within the product security regulations where relevant. Do not assume a business purchase establishes an exemption. For appliances intended for consumer sale, review the product security scope before ordering. If importing for resale, arrange annual electrical-equipment producer registration; the official guidance distinguishes equipment brought in solely for your own use.

Worked duty example

Illustrative example, not a quote: Illustrative small-business batch of diskless network-attached storage appliances under 8471 50 00 00, invoiced at £10,000 free on board, with £1,000 of freight and insurance to the UK. The customs value is £11,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £11,000, so it is £2,200. 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

Build: compare processor, memory, drive identity, power supply and firmware with the approved specification; record serial numbers.

Storage: test drive recognition, file transfer, permissions, disk replacement and recovery using disposable test data.

Operation: run sustained transfers with the agreed drive configuration; check cooling, fan noise, network reconnection and restart after interrupted power.

Handover: check administrator access, update installation, reset behaviour, English instructions and matching compliance documents during quality inspection.

What goes wrong

A sample can perform differently from production after changes to memory, network controllers, drives or firmware. A populated appliance may arrive with substituted drives or an untested compatibility combination. Require written approval of substitutions and repeat the agreed transfer and recovery checks.

Storage redundancy does not replace a separate backup. Test restoration as well as normal file access. Agree who fixes firmware faults and how updates remain available if the factory changes its software supplier. For tape backup equipment, see our magnetic tape backup drive sourcing guide.
