Duty Drawback in Canada: How Exporters Can Recover Tariffs Already Paid

If you import goods into Canada, pay customs duty on them, and later ship them out of the country, you may be able to get that duty back. That refund is called duty drawback, and it is one of the most under-used cost savings available to Canadian exporters.

This guide to duty drawback in Canada covers what drawback is, who qualifies, how to file a claim with the Canada Border Services Agency (CBSA), what you can and cannot recover, and how drawback compares with USMCA (CUSMA) exemptions and the Duties Relief Program.

What Is a Duty Drawback?

A duty drawback is a refund of customs duties, excise taxes, and certain other charges paid on imported goods. In Canada, duty drawback applies when those goods are later exported, used to make a product that is exported, or destroyed under CBSA supervision.

The logic is simple. Import duties are meant to apply to goods consumed in Canada. If the goods (or the product they became part of) leave the country instead, the government lets you recover the duty you paid.

Drawback is not the same as a USMCA exemption

These two are often confused, but they work at opposite ends of the process:

• USMCA (CUSMA) exemption: qualifying goods that meet the rules of origin never owe duty at the border in the first place.
• Duty drawback: recovers duty that was already paid, typically on non-originating inputs that are later exported or re-exported.

A simple example

A Canadian furniture maker imports steel hardware from Asia and pays duty when it clears customs. The hardware goes into finished cabinets, which are then sold and exported. Because the imported component left Canada inside an exported product, the duty paid on that hardware can potentially be recovered through drawback.

The same logic applies to a distributor who imports goods and re-exports some of them unchanged, for example to customers outside North America.

Canada’s Duty Drawback Program: Who Qualifies

The duty drawback program in Canada is run by the CBSA under the Customs Tariff and the Goods Imported and Exported Refund and Drawback Regulations. The program rules are set out in CBSA Memorandum D7-4-2, Duty Drawback Program.

A claim can be made by the importer, exporter, processor, owner, or producer of the goods. Your goods generally qualify in one of three scenarios:

1. Exported in the same condition. You import goods, pay duty, and later export them without changing them.
2. Used to manufacture an exported product. Imported materials or components are processed in Canada, or directly consumed in production, and the finished goods are exported.
3. Destroyed under CBSA supervision. Imported goods that are defective or unsellable are destroyed with CBSA oversight instead of being exported.

The goods must actually be exported, or “deemed exported” under the Customs Tariff, before you file.

Exports to the US and Mexico have extra rules

If you export manufactured goods to a CUSMA country, the refund on non-originating materials is capped. Canada’s Customs Tariff limits it to the lesser of the duty you paid on import into Canada and the duty paid when the goods enter the US or Mexico. These “lesser of two duties” rules are explained in CBSA Memorandum D7-4-3. Goods exported in the same condition as imported are not affected by this cap.

Drawback vs. the Duties Relief Program

The drawback program has a sister program, the Duties Relief Program (Memorandum D7-4-1). Duties Relief lets licensed companies defer duty at import on goods they plan to export. Drawback refunds duty you have already paid. If you export regularly, it’s worth deciding which program fits before your next shipment, since Duties Relief avoids tying up cash in the first place.

How to Claim Duty Drawback in Canada

To claim customs duty drawback in Canada, you file Form K32, Drawback Claim with the CBSA, along with documents proving the import, the duty paid, and the export or other qualifying use. Since the rollout of the CBSA Assessment and Revenue Management system (CARM) in October 2024, claims and supporting documents are submitted through CARM.

Step-by-step

1. Confirm eligibility. Check that your goods fit one of the three qualifying scenarios and that you are within the filing window.
2. Match imports to exports. Identify which import entries correspond to which exported goods, or which components went into which exported products.
3. Calculate the refund. Work out the duty attributable to the exported portion. For exports to the US or Mexico, apply the CUSMA “lesser of two duties” rule where it applies.
4. Complete Form K32. The completion instructions accompany the form.
5. Submit with supporting documents and keep your records in case the CBSA asks for verification.

Documents you will typically need

• The original customs entry and import documents
• Proof that duty was paid
• Manufacturing, bill-of-materials, or inventory records linking the imported goods to the exported product
• Proof of export, such as export declarations, bills of lading, and commercial invoices
• If someone else exported the goods, a waiver from the exporter (Form K32B, Drawback Certificate of Sale for Exportation)
• For CUSMA-affected exports, “satisfactory evidence” of the duty paid in the US or Mexico

Filing deadline

Drawback claims generally must be filed within four years of the release date of the imported goods. A five-year window applies in specific cases, such as spirits used to make exported distilled spirits. Treat four years as your working deadline and file sooner where you can.

Duty Refunds in Canada: What Exporters Commonly Recover

A duty refund in Canada through drawback covers most border charges, but not sales tax.

Typically recoverable:

• Customs duties, including Most-Favoured-Nation (MFN) tariffs
• Excise taxes paid on import
• Surtaxes, including Canada’s 2025 counter-tariffs on certain US goods. CBSA has confirmed that drawback is available for these surtaxes, and goods of US or Mexican origin are not subject to the CUSMA “lesser of two duties” cap.

Not recoverable through drawback:

• GST/HST. CBSA states that GST/HST cannot be refunded by drawback. Most registered businesses recover import GST/HST through input tax credits, and the Canada Revenue Agency runs separate export programs for GST/HST relief.
• Anti-dumping and countervailing (SIMA) duties on goods affected by the CUSMA restrictions.

Recovery is proportional

You can only recover duty on the portion that qualifies. If you imported 1,000 units and exported 600, drawback covers the duty on those 600 units, not the full shipment.

Why so much drawback goes unclaimed

Many exporters never file, either because they don’t know the program exists or because linking specific imports to specific exports feels like too much paperwork. With US tariffs and Canadian counter-tariffs raising landed costs since 2025, the money at stake is larger than it used to be. A quick review of the last four years of import entries is often worth the effort.

Duty Drawback vs. USMCA Exemptions vs. Duties Relief

Canada offers three main ways to avoid or recover duty on goods tied to exports. The duty drawback program is the one that works after duty is already paid.

Program	When it applies	Timing	What’s recovered or avoided
Duty Drawback	Imported goods are exported as-is, used to make exported goods, or destroyed	After duty is paid (refund)	Customs duties, excise taxes, surtaxes; not GST/HST
USMCA (CUSMA) Duty Exemption	Goods meet CUSMA rules of origin and move between Canada, the US, and Mexico	At the border (no duty owed)	Customs duty on qualifying goods
Duties Relief Program	Licensed importer brings in goods intended for export within four years	Before duty is paid (deferral)	Customs duties and excise taxes are deferred, then cancelled on export; not GST/HST

Which one fits? USMCA prevents duty at the border for goods that qualify on origin. Duties Relief defers duty up front for licensed companies that plan to export. Drawback refunds duty you already paid when neither of the other options was used.

Frequently Asked Questions

How long does a duty drawback claim take in Canada?

Processing time depends on how complex the claim is and how complete your documentation is. Straightforward claims with clear import-to-export records generally move faster than claims where the CBSA has to verify manufacturing or inventory links. Incomplete or poorly documented claims are the most common cause of delays, so exporters who work with a customs broker experienced in duty drawback in Canada tend to see fewer holdups.

Can I claim duty drawback on goods exported to the US?

Yes. Exporting to the US is a common drawback scenario, but CUSMA adds limits. Goods exported in the same condition as imported can usually get a full refund. If imported non-originating materials were used to make goods exported to the US or Mexico, the refund is capped at the lesser of the duty paid in Canada and the duty paid on entry into the US or Mexico. Goods that already entered duty-free under CUSMA have no duty to recover.

What is the difference between duty drawback and the Duties Relief Program?

Timing is the key difference. The Duties Relief Program lets a licensed importer defer duty at import on goods intended for export, so the duty is never paid as long as the goods leave Canada within the program’s timeframe. Duty drawback works in reverse: you pay duty at import, then apply for a refund after the qualifying export or use has happened.

Do I need a customs broker to file a drawback claim?

No, it isn’t required. A business can file Form K32 with the CBSA directly. However, drawback claims need detailed records linking specific imports to specific exports or manufacturing uses, which can be administratively complex. Many exporters use a customs broker or trade compliance specialist to reduce errors and delays, especially for high-value or recurring claims.

How far back can I claim duty drawback in Canada?

Claims for duty drawback in Canada generally must be filed within four years of the release date of the imported goods, with a five-year window in limited cases. If you suspect you have unclaimed drawback from past shipments, review your import records now. Every month you wait, the oldest eligible entries age out of the window.

Is GST included in a duty drawback refund?

No. The CBSA states that GST/HST cannot be refunded through drawback. Drawback covers customs duties, excise taxes, and surtaxes. Most GST/HST-registered businesses recover import GST/HST through input tax credits on their regular returns. The Canada Revenue Agency also runs export-focused GST/HST relief programs, so check with the CRA or your accountant for your situation.

What form do I use to claim duty drawback in Canada?

Use CBSA Form K32, Drawback Claim. Submit it with supporting documents proving the original import, the duty paid, and the export or other qualifying use. Related forms include K32A and K32B, which are waiver certificates used when someone other than the claimant exported the goods. Errors or missing paperwork are the most common reasons claims are delayed or rejected.

The Bottom Line

If you import goods, pay duty, and later export them, duty drawback can put that money back in your business. Start by pulling the last four years of import entries, matching them against your exports, and estimating what’s recoverable. Then decide whether to file yourself or work with a customs broker.
