Some confuse duty drawbacks and duty refunds by thinking that they're essentially the same thing. However, both of these customs processes function differently and serve different purposes. 

Knowing how and when to claim duty drawbacks versus duty refunds will have a positive impact on your bottom line. Understanding how each process works can help importers recover costs and improve cash flow.

What is a duty drawback?

A duty drawback is a refund of customs duties that were originally paid on imported goods. You can qualify for this type of benefit for goods that will be exported, will be destroyed, and other, specific qualifying factors. The primary purpose of this customs mechanism revolves around businesses that engage in global trade by ensuring that they aren’t penalized with duties on goods that don’t remain in the domestic market.

How duty drawbacks work in Canada

The duty drawback system is part of the Canada Border Security Agency’s (CBSA) duty deferral program. Importers can apply for a refund of duties under several scenarios, including:

  • Goods re-exported in the same condition they were imported.
  • Goods that are processed, assembled, or manufactured in Canada, and then exported.
  • Goods imported for display, development, or demonstration purposes before being exported.
  • Surplus or obsolete goods that are exported or destroyed rather than sold domestically.

These rules are outlined in the CBSA D7 Memoranda, which provides detailed guidance on documentation and time limits.

What Is a duty refund?

A duty refund is issued when an importer recovers duties that were paid in error or overpaid. Unlike a drawback, a refund isn’t connected to the export or destruction of goods. Duty refunds intend to correct mistakes and claim benefits that were missed during the initial import entry.

Common scenarios for duty refunds

Importers may qualify for refunds in several cases, such as:

  • Free trade agreement claims after importing goods
  • Retroactive duty refunds
  • Price adjustments and vendor credits that reduce value of duty
  • Defective or undelivered goods where the invoice value was reduced
  • Refunds for certain end-use exemptions

Goods that qualify for a duty-free use, such as industrial inputs for specific manufacturing processes, may be eligible for a refund if proper certificates are provided. Canadian importers can file a Customs Adjustment Request with the CBSA to recover overpaid duties. 

Key differences between duty drawbacks and duty refunds

A duty drawback is triggered when goods are exported, destroyed, or used for a specific qualifying purpose. A duty refund occurs when an importer discovers an overpayment or makes a correction to previous import accounting.

In terms of timing, a duty drawback claim is typically made after the goods have been exported or destroyed, while a duty refund claim is filed after the importer identifies and confirms an overpayment.

Structurally, the duty drawback system operates under a formal program: the CBSA Duty Deferral Program. Duty refunds, however, are handled on a case-by-case basis and generally involve submitting a correction or adjustment to customs records.

The purpose of each program also differs: duty drawbacks are designed to encourage exports and global trade by refunding duties on goods that don’t remain in the domestic market, while duty refunds aim to correct import errors and recover overpaid duties.

The impact on importers

Many importers miss out on significant potential duty recoveries simply because they don’t take advantage of these programs. Understanding and applying for duty refunds and drawbacks can:

  • Recover significant amounts of paid duty
  • Improve cash flow and reduce landed costs
  • Enhance profitability on export operations

Stop leaving money on the table

Failing to apply for duty drawbacks or duty refunds is a lost opportunity. After all, both of these customs processes exist to support businesses and ensure a fair application of duties.
