Key Takeaways
- Duty drawback claims in Canada have a four-year window under the Customs Act, but you need clean documentation from the original CAD and evidence of export or destruction.
- CARM's monthly K84 statement now surfaces overpayments faster than the old quarterly cycle, giving importers a tighter feedback loop to spot correction candidates.
- Geopolitical supply shifts that move production out of AD/CVD subject countries can reset your duty baseline, but only if you file a proper origin change and HS re-classification upfront.
- Large refunds draw CBSA verification scrutiny; if you're claiming back six figures, expect a request for commercial invoices, bills of lading, and proof of payment within 30 days.
McCormick's refund and what it means for Canadian duty strategy
McCormick's $28 million U.S. tariff refund made supply-chain headlines this week, but the story Canadian importers should pay attention to isn't the dollar figure. It's the mechanism: a successful duty drawback claim tied to supply-chain cost shocks and re-routing decisions driven by geopolitical risk. The company plans to use the returned funds to offset higher logistics and material costs stemming from conflict in the Middle East.
Canada's duty drawback and correction framework works differently than the U.S. system, but the underlying logic is identical. If you overpaid duty because of a classification error, a supplier invoice mistake, or a change in origin that wasn't reflected on your Commercial Accounting Declaration, you can recover it. The question is whether your documentation supports the claim and whether you're inside the four-year limitation period set by Section 74 of the Customs Act.
CARM and the K84 monthly statement
One operational shift under CARM that importers still underestimate is the monthly K84 accounting statement. Before October 2024, most brokers reconciled duty and GST on a quarterly cycle. Now every importer with an RPP bond receives a detailed monthly statement showing every CAD filed, every payment posted, and every outstanding balance.
That tighter feedback loop surfaces overpayments faster. If your broker fat-fingered an HS code or applied the wrong CUSMA origin preference, you'll see the variance within 30 days instead of 90. That matters because the 90-day voluntary correction window under CBSA's Voluntary Disclosure Program starts ticking from the date of CAD acceptance. Catching the error in month one leaves you eight weeks to file the correction without penalty. Catching it in month three leaves you days.
We routinely see importers carry a $15,000 to $40,000 rolling credit on their K84 after the first quarter under CARM, simply because the old quarterly reconciliation habit hasn't caught up to the new monthly cycle. If that credit reflects real overpayment and you don't file a drawback claim, the money sits with the Crown.
Duty drawback mechanics in Canada
Canadian duty drawback falls into two buckets: export-driven and correction-driven.
Export-driven drawback applies when you import goods, pay duty, and then re-export them within a set period. The classic example is manufacturing inputs that become part of a finished good shipped to the U.S. or Mexico under CUSMA. You file a drawback claim with proof of export—usually a commercial invoice, bill of lading, and the original CAD showing duty paid—and CBSA refunds the duty. The four-year limitation period under Section 74 of the Customs Act applies, so documentation discipline matters.
Correction-driven drawback applies when you overpaid duty because of an error: wrong HS classification, incorrect origin claim, or a SIMA margin applied to non-subject goods. You file a CAD correction via the CARM Client Portal, attach supporting documents, and request a refund. If CBSA agrees, the refund posts to your RPP account or goes out as a cheque if you're a non-resident importer filing through an NRI arrangement.
Both paths require clean documentation. CBSA's default position is that the importer owns the accuracy of the declaration. If you're claiming back duty, you need to prove the original CAD was wrong and provide the correct tariff treatment, origin certificate, or supplier invoice that supports the lower rate.
Geopolitical cost shocks and tariff treatment
McCormick's refund ties back to supply-chain re-routing driven by conflict in the Middle East. For Canadian importers, geopolitical shocks often force a choice: stick with an existing supplier in a region now subject to higher freight risk, longer lead times, or new trade measures, or shift sourcing to a CUSMA, CETA, or CPTPP partner and lock in preferential duty rates.
That shift doesn't automatically generate a drawback claim. If you paid 6.5% MFN duty on goods from India last year and now source the same product from Mexico at zero duty under CUSMA, the past shipments remain subject to the MFN rate. You can't retroactively apply CUSMA origin to a CAD filed before you changed suppliers.
What you can do is ensure the new supplier provides a proper CUSMA certificate of origin, file the preference claim on the first shipment, and avoid overpaying duty going forward. If your broker misses the preference claim and files at MFN, you have 90 days to correct it under the Voluntary Disclosure Program without penalty. After 90 days you can still correct, but if CBSA discovers the error first during a verification, you face AMPS penalties starting at Level 1 for negligence.
The other scenario where geopolitical shifts matter is SIMA. If your supplier sits in a country subject to anti-dumping or countervailing duties—China, South Korea, Vietnam for certain steel, aluminum, and chemical products—and you move sourcing to a non-subject country, your duty baseline drops immediately. But you need to file a new HS classification review and update your CAD template to reflect the origin change. Fail to do that and CBSA will continue applying the AD/CVD margin, because the system defaults to the last-filed tariff treatment.
Large refunds and CBSA verification
McCormick's $28 million refund would trigger a multi-month verification process in Canada. CBSA doesn't hand back six-figure sums without scrutiny. Any drawback claim above low five figures typically prompts a request for commercial invoices, proof of payment, proof of export, and a detailed explanation of the correction.
Section 42.01 of the Customs Act gives CBSA 30 days to request documentation and importers 30 days to respond. If you miss the deadline or provide incomplete records, CBSA can deny the claim outright. If the claim involves origin, CBSA may escalate to a full origin verification under CUSMA Chapter 5 or CETA Chapter 2, which adds another 60 to 90 days and requires your supplier to respond directly to CBSA's queries.
Most Canadian importers don't file claims at McCormick scale, but the same documentation standard applies whether you're claiming back $5,000 or $500,000. If your commercial invoices live in a filing cabinet at FENGYE's Montreal warehouse and your bills of lading are buried in your freight forwarder's archive, pull them before you file. CBSA won't wait.
When to pursue a correction versus when to let it go
Not every overpayment justifies a drawback claim. If you paid $200 extra duty because your broker misclassified a single shipment and you're now 18 months past the CAD date, the administrative cost of pulling records, drafting the correction, and responding to CBSA queries probably exceeds the refund.
The break-even point sits somewhere around $2,000 for most importers. Below that threshold, the time cost outweighs the cash recovery unless you're filing corrections in batch. Above $10,000, it's worth the effort, especially if the error is systemic and affects multiple CADs filed under the same tariff treatment.
If you import the same product monthly and discover your broker has been applying the wrong HS code for two years, you're looking at 24 CADs to correct. Multiply the per-shipment duty error by 24 and the refund often lands in five figures, well inside the four-year limitation period. That's when you escalate the correction to a formal drawback claim and loop in CanFlow's compliance team to ensure the correction logic holds under CBSA review.
CARM and the future of duty recovery
CARM's monthly K84 cycle and the centralized RPP bond structure make duty corrections more transparent than the old B3 regime, but they also surface errors faster. Importers who treat the K84 as a passive accounting statement instead of an active management tool leave money on the table.
The four-year drawback window under the Customs Act is generous compared to other jurisdictions, but it's not automatic. You need to file the claim, provide the proof, and survive CBSA's verification process. If your documentation practice is solid and your broker relationship includes regular tariff reviews, duty recovery becomes a routine part of your import program instead of a crisis-driven scramble.
If your last CBSA verification turned up classification errors or your K84 shows unexplained credits sitting for more than two quarters, that's a signal to audit your CAD history. Most importers wait until a supplier changes or a freight lane shifts to review their tariff treatment. The importers who treat duty management as a quarterly discipline instead of an annual event are the ones who catch the $20,000 corrections before they age out of the four-year window.
McCormick's $28 million refund won't repeat at mid-market scale, but the lesson does: duty paid is not duty owed. If your records support a lower rate and you're inside the limitation period, file the claim. Get in touch if your K84 shows a pattern you can't reconcile or if you're sitting on a multi-year supplier change that never triggered a tariff review.
Frequently Asked Questions
How long do I have to file a duty drawback claim with CBSA?
You have four years from the date duties were paid, per Section 74 of the Customs Act. The clock starts when CBSA releases the goods and posts the accounting, so track your CAD acceptance dates carefully. Miss the window and the money stays with the Crown.
Does CARM make it easier to spot overpaid duty?
Yes. CARM's monthly K84 statement replaces the old quarterly cycle and itemizes every CAD, payment, and adjustment. Most importers now catch data-entry errors or incorrect tariff treatment within 30 days instead of 90, which shortens the correction timeline and keeps the refund process inside the same fiscal quarter.
What counts as acceptable proof for a drawback claim?
CBSA wants the original CAD, commercial invoice, proof of payment, and evidence the goods left Canada or were destroyed under Customs supervision. Export manifests, bills of lading with a foreign destination, or a CBSA Form E29B for destruction all work. Email screenshots and vague packing lists do not.
Can I reclaim duty if I switch suppliers to avoid SIMA measures?
No. Drawback applies to goods physically exported or destroyed, not to future shipments from a new origin. If you move sourcing from a SIMA-subject country to a CUSMA or CETA partner, you pay the lower rate going forward, but past shipments remain subject to the AD/CVD margins in force when they cleared.
How does CBSA handle large refund claims?
Any claim above low five figures typically triggers a verification under Section 42.01 of the Customs Act. CBSA will request commercial documentation, payment records, and proof of export within 30 days. If your files sit in a box at FENGYE's Montreal sufferance warehouse, pull them before you file the claim.
Does CARM change the correction window for mis-classified goods?
No. You still have 90 days from the date of CAD acceptance to self-correct an HS classification or origin claim without penalty under CBSA's Voluntary Disclosure Program. After 90 days you can still correct, but if CBSA finds the error first, you face AMPS penalties starting at Level 1 for negligence.
What happens if I file a drawback claim and CBSA denies it?
You receive a written decision citing the Customs Act section and a 90-day appeal window to the CBSA Recourse Directorate. If that fails, you can escalate to the Canadian International Trade Tribunal under Section 67. Most denials come down to missing export proof or filing past the four-year limit.
