Duty drawback refunds duties on goods later exported, but claims live or die on records linking the import to the export. This guide lists the documents to keep, how long to keep them, and the habits that make a claim routine instead of archaeology.

## Drawback is a matching exercise

The claim asks a simple question with strict proof: were the goods you exported the goods, or made from the goods, you paid duty on? Every document in the file exists to support that link. A missing link does not reduce the refund; it usually ends the claim for that shipment.

Two routes exist in most schemes: unused goods exported as imported, and goods manufactured into a new product before export. The second needs production records as well, showing quantities in and out. Decide which route each product line uses before designing the filing system, because the evidence differs.

## The core file, entry to export

For each claim keep the import entry summary with duty paid, the supplier invoice, proof of payment, goods received notes, the export invoice, the bill of lading or air waybill, and the export declaration. File them against a single claim reference at the time of export, while the trail is warm and the people involved remember the shipment.

Inventory linkage is where claims most often fail. If imported stock goes into a common pool, your stock system needs to show the accounting method the scheme allows, applied consistently. Reconstructing which batch went where, a year later, from memory and spreadsheets, rarely survives an audit.

## Keep records longer than feels necessary

Retention periods in drawback schemes commonly run three to five years from payment of the claim, and audits arrive near the end of that window, not the start. A retention rule that destroys entry documents after two years quietly destroys claim value the business has already earned.

Put drawback files under the same legal hold discipline as tax records: named owner, fixed retention, no casual clear outs during office or system moves. System migrations are a classic loss point, where scanned documents survive but the index linking them to claims does not.

## Build the habit at receiving and dispatch

The cheapest drawback system is a checkbox: receiving flags duty paid stock, dispatch flags exports of flagged stock, and the claim file assembles itself from the two flags. Retrofitting flags across a year of shipments is the expensive version, and some of those claims will simply be abandoned.

Start with the highest duty product line that is regularly re exported, prove the file on a few shipments, then extend. One working line funds the attention for the rest, and the first audit or query teaches the team exactly which fields the scheme's reviewers actually press on.

Finally, cost the habit honestly against the prize. For a regular exporter of duty paid goods, drawback is often worth several percent of the goods value, year after year, for the price of disciplined filing at two moments the business already handles: receiving and dispatch. Set against that, the common reason claims are never made, that nobody had time to build the file, reads differently. The file is a by product of good records. Build the records once, and the refund becomes an annual routine rather than a project.

## Frequently asked questions

## What is duty drawback?

A refund of import duties paid on goods that are later exported, or manufactured into goods that are exported. The claim depends on proving the link between the duty paid import and the export.

## Which records does a drawback claim need?

The import entry with duty paid, supplier invoice and payment proof, receiving and inventory records linking import to export, and the export invoice, transport document, and export declaration, filed under one claim reference.

## How long should drawback records be kept?

Commonly three to five years after the claim is paid, matching the scheme's audit window. Keep them under the same retention discipline as tax records, including through system migrations.

## Where do drawback claims usually fail?

At the inventory link: proving the exported goods were the imported goods when stock sits in a common pool. A consistent, allowed accounting method recorded at the time is what survives audit.
