The duty you paid may not be the duty you owed.
An incorrect commodity code, a missed preference or a declaration issue can travel through thousands of imports unnoticed.
For businesses with substantial customs spend, the right question is whether the actual entry data and underlying documents support a defensible repayment — not what a generic refund calculator predicts.

The opportunity is in the detail
Large imports. Small errors. Material exposure.
Not every importer has overpaid duty. The economics improve where there is meaningful duty spend, a lengthy declaration history, complex SKUs and access to documentary evidence.
Commodity classifications
Check whether product specifications and the correct classification at the import date align with the tariff declared.
Trade preferences
Determine whether legally valid origin evidence and the applicable agreement support a different rate.
Returned goods & reliefs
Review situations where documented returns or eligible customs procedures may alter duty treatment.
Usually up to three years
A moving window, not an unlimited refund.
HMRC normally allows three years to seek repayment of overpaid import duty, with different deadlines for rejected imports and withdrawn declarations. The correct process depends on the importer, declaration route and circumstances.
For VAT-registered businesses, overpaid import VAT is ordinarily corrected through the VAT return rather than a customs repayment request. That distinction must be kept clear.
The right starting documents
CDS import item reports
Commodity code, customs value and amount of duty at the line level.
Commercial evidence
Invoices, product details, origin statements and relevant shipping records.
Authority & audit history
Who imported the goods, who holds the data, and whether an earlier review or HMRC decision affects the case.
A careful review sequence
From declarations to a defensible conclusion.
Qualify the importer
Confirm annual customs duty paid, number of entries, complexity, authority and historical period.
Examine line data
Use authorised Customs Declaration Service reports; surface anomalies for technical review.
Check the law and facts
Codes, effective tariff rules, origin evidence and prior decisions must support the proposed treatment.
Decide the next action
Only a substantiated overpayment should progress to a properly authorised claim through the relevant HMRC process.
For import-intensive businesses
Know whether your data is worth auditing.
A finance director should be able to understand the likely size and cost of a potential assessment before releasing years of sensitive import records.
Try the readiness screen →What we won't promise
No invented “average recovery”, blanket claim that customs brokers got codes wrong, or guarantee that a lower tariff can be used retrospectively. A repayment depends on actual law, evidence, deadlines and HMRC's decision.
For independent sources, see the HMRC repayments guide.
Practical customs tools
Turn a suspected duty error into a testable proposition.
Before spending money on a reclaim, separate the tax from the fee, the legal route from the spreadsheet, and the evidence from the hypothesis.
Repayment routes
CDS, C285 or VAT-return adjustment?
Identify the route and deadline, avoid common false positives, and see what actually supports a claim.
