Duty recovery & declaration assurance
Two numbers, out of your own entries.
Give us twelve months of import declarations and we recompute every line against the UK Trade Tariff: the duty you overpaid and can still reclaim, and the duty you underpaid that HMRC can assess four years back, with interest and penalties. Most importers have both, and only ever go looking for one.
Give it your entries
HMRC MSS data, a CDS export, or your broker's spreadsheet — column names are detected automatically, and we tell you which column we used for what so you can check it. Nothing is stored: the file is parsed, audited, and the result handed straight back.

What it looks for
- Preference never claimed. Goods that qualified for a lower rate under a trade agreement, entered at the full third-country rate. Nothing on the entry tells an importer a cheaper rate existed.
- Anti-dumping duty not paid. Usually the largest single number, and it recurs on every entry of that code and origin until someone notices.
- Duty over- or under-paid against the rate that actually applied, on the value declared.
- Commodity codes that do not resolve against the tariff — rate, licensing and origin all hang off the code.
- Duty paid outright where a relief regime would have suspended it. If goods are processed, stored or re-exported, Inward Processing or customs warehousing changes the cashflow permanently.
