How to file a CBSA duty drawback claim
Filing a duty drawback claim is easier than you think. The CBSA Assessment and Revenue Management (CARM) client portal simplifies the process, so you can manage customs and revenue digitally.
Before you begin, you need to:
- Register for the CARM portal
- Create a user account
- Ensure you have a valid BN15 importer program account
Once registered, you can submit your claim directly through the portal. Here’s a step-by-step guide:
- Confirm eligibility: Ensure the goods were imported and then exported or destroyed. Claims must be filed within:
- Four years of import for most goods
- Five years for goods that were destroyed. For example, items that weren’t exported because they were damaged, obsolete, or surplus.
- Gather documentation: You’ll need proof of import and export, including:
- Import records: Commercial invoices, customs declarations, packing list, etc.
- Export declarations: Export invoice, shipping document, bill of lading and U.S. customs declaration.
- Proof of manufacturing or processing (if applicable): Bill of materials (BOM) is required if goods were altered before export.
- Waivers (if applicable): Required when multiple parties are involved.
"Waivers are essential when more than one party in the supply chain could be eligible to claim the refund,” says Rhonda Galbraith, director of Canadian Trade Services, GHY International. “These waivers ensure that only one party claims the drawback and that CBSA has a clear record of consent from all other eligible entities.” She recommends getting waivers early to avoid delays, especially in multiparty supply chains.
- Submit your claim: Complete the drawback claim (form K32) and all supporting documentation and submit through the CARM portal.
- Track your refund: Refunds may be full or partial, depending on the goods and documentation. Interest may be paid on delayed refunds.
