Sourcing LTO backup tape cartridges from China

Duty on blank and recorded backup tapes

Read from the UK Trade Tariff on 30 September 2026, heading 8523 covers recording media, including magnetic tapes. Blank LTO backup tape cartridges fall within unrecorded magnetic tapes under 8523 29 15 00; recorded tapes fall within 8523 29 19 00. The table separates purchasing variants sharing these tariff lines.

Both lines carry 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspension or attached import control for either line. For the wider heading, see the blank optical discs guide.

Include the commodity code on the import declaration. Confirm the commodity code using the cartridge specification and whether it contains recorded data. Zero duty does not remove import VAT; see UK import duty and VAT.

Specify the cartridge and the restore environment

Name the LTO generation, manufacturer and part number, native capacity, rewritable or write-once format, and whether cartridges must be new and blank. Identify the target drive, library and backup software. Ask for written compatibility confirmation against those exact models, rather than accepting a general compatibility claim.

Agree barcode content, label placement, individual cases, batch traceability and packing protection. Request storage and transport instructions from the manufacturer. For branded cartridges, request evidence of the authorised supply channel and check it independently before accepting production stock.

Request material information for the cartridge shell and tape coating. Under UK REACH, supplying an article containing a Candidate List substance above 0.1% by weight requires safe-use information for business recipients, including the substance name. Importing articles containing Candidate List substances may also require notification to HSE.

Worked duty example

Illustrative example, not a quote: Illustrative small-business order of blank LTO backup tape cartridges under 8523 29 15 00, invoiced at £40,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £41,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £41,500, so it is £8,300. 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: match manufacturer, generation, part number, format, batch references and seals against the purchase specification; investigate signs of relabelling or previous use.

Housing and packing: check for cracked cases, damaged cartridge doors, loose components, contamination and moisture; check individual protection against the approved packing sample.

Library recognition: scan barcodes in the intended library, check for duplicate identifiers, and confirm that sampled cartridges load, unload and report the expected media type.

Write and restore: write representative backup data to production samples, read it back and compare it with the original; retain drive logs and investigate errors through quality inspection.

What goes wrong

A cartridge can look correct yet be unsuitable for the installed drive or library. Wrong generations, incorrect barcode labels, previously used stock sold as new and damaged housings are reasons to hold a batch. Acceptance should include a restore test in the buyer's intended environment.

Compressed capacity claims can obscure the native capacity needed for purchasing. Specify native capacity separately and agree how sample testing affects saleable stock, especially for write-once cartridges. Keep questionable batches separate until the supplier explains the discrepancy and replacement samples pass the agreed checks.
