Sourcing solid-state drives from China
Solid-state drives from China carry 0% UK duty across the recorded and unrecorded lines, with no listed trade remedies. Zero duty does not remove product compliance obligations: check hazardous-substance documentation and importer labelling, and verify actual capacity. Cambridge China Bridge sources solid-state drives.
Zero duty on solid-state drives
Read from the UK Trade Tariff on 5 October 2026, heading 8523 covers recording media, including solid-state non-volatile storage devices. This guide concerns solid-state drives. The table separates internal and external products within the same recorded or unrecorded commodity lines.
Both relevant lines carry 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls for these lines. This describes customs measures, rather than permission to sell a non-compliant product.
Confirm the commodity code using the drive specification and whether content is recorded before shipment. For other storage media within the heading, see USB drives and memory cards.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Internal solid-state drives, unrecorded | 8523 51 10 00 | 0% | None |
| Internal solid-state drives, with recorded content | 8523 51 90 00 | 0% | None |
Specify the flash, controller and sustained performance
Agree the interface, connector, physical dimensions, usable capacity, controller, flash type and firmware revision. State whether the drive is internal or supplied in an external enclosure, and identify the cable and host equipment used for acceptance tests. Require approval before the factory substitutes flash or controllers.
Define sustained read and write performance using an agreed workload, host and temperature conditions. Check behaviour after the write cache fills, rather than accepting a brief peak-speed demonstration. Agree endurance claims, warranty handling and whether the application needs power-loss protection.
Obtain the hazardous-substance conformity declaration and electromagnetic compatibility evidence described in the related storage guide. Under hazardous-substance rules, individual products must show the importer’s name or trademark and a contactable address on the product or packaging. Manufacturers of apparatus covered by electromagnetic compatibility rules must provide relevant instructions in English. Electrical equipment producers must register annually; check your position before selling imported drives.
Worked duty example
Illustrative example, not a quote: Illustrative batch of unrecorded internal solid-state drives under 8523 51 10 00, invoiced at £1,500 free on board, with £600 of freight and insurance to the UK. The customs value is £2,100. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £2,100, so it is £420. 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
Capacity: write and read back the full stated capacity on production samples, recording verification errors rather than trusting the capacity reported by the controller.
Performance: measure sustained transfers after the cache fills, record temperatures and check for disconnections or speed drops against the agreed test conditions.
Components: compare controller and flash markings, firmware, connectors and enclosure construction with the approved sample; check the supplied cable on the intended host.
Identification: match model and serial identifiers across drives, packaging and test records; check importer details, English instructions and any agreed preloaded content at inspection.
What goes wrong
A drive can report the promised capacity while losing files beyond the flash’s actual capacity. Substituted or downgraded flash can also change performance and durability. Keep an approved component specification and repeat full-capacity verification on samples drawn from the shipment.
A short benchmark can conceal slow sustained writes or heat-related speed reductions. Connector mismatch, unsuitable cables and firmware differences can cause failures on the buyer’s equipment. Test the delivered configuration, retain batch records and agree how failed drives and potentially sensitive returned data will be handled.

Frequently asked questions
What is the UK import duty on solid-state drives from China?
The supplied tariff record shows 0% on both recorded and unrecorded solid-state storage lines, with no listed anti-dumping or countervailing duty.
How do I check a solid-state drive’s real capacity?
Write and read back its full stated capacity on production samples. The capacity reported by the operating system alone does not verify the flash’s actual capacity.
What should I specify before ordering solid-state drives?
Agree the interface, dimensions, controller, flash type, firmware, capacity and sustained-performance test. Include the enclosure and cable where supplied.
Does zero import duty mean the drive is ready for UK sale?
No. Check the product compliance evidence and importer labelling. Electrical equipment producers must register annually; establish your responsibilities before sale.
