Overpaid duty doesn't announce itself, so most importers never claim it back
In theory, Customs only collects the duty that’s actually due. In practice, it’s common for importers to inadvertently overpay Customs duty, and because Customs has no reason to flag it, the overpayment sits there unnoticed, often for years.
The only way to find it is to look. We review your import records, identify where duty has been overpaid, and claim it back from Customs on your behalf.
