Shipping Broker Role When Suppliers Are Importer of Record: Who Gets the Duty Refund?

Key Takeaways

• If your supplier is the non-resident importer of record, they hold the legal right to any duty drawback or refund unless your contract says otherwise.
• CARM Client Portal access and CAD filing authority determine who can actually submit the refund claim to CBSA.
• A four-year correction window exists under the Customs Act, but most importers miss it because the supplier’s broker filed the original entry.
• Clear purchase-order language assigning refund rights saves six months of back-and-forth when tariff classifications get corrected or trade agreements expand.

When the Supplier Holds the Import Filing, Who Captures the Refund?

The O’Reilly Automotive earnings-call disclosure is a useful reminder: if your sourcing model makes the supplier the importer of record, you likely have no direct claim to tariff refunds, drawback recoveries, or origin preference corrections. That entire upside sits with whoever filed the Commercial Accounting Declaration (CAD) through CBSA’s CARM system.

For Canadian importers working with non-resident suppliers, this is not an edge case. It is the default. A shipping broker working on behalf of an NRI supplier controls the CAD filing, the HS 6-digit classification, the origin claim under CUSMA or CETA, and any subsequent correction filings. Unless your purchase order explicitly assigns refund rights back to you, the supplier and their broker pocket the savings when duties drop or tariff programs expand.

We see this every month: a Canadian buyer discovers a better tariff classification six months after import, but the supplier’s broker filed the original entry. The buyer has no CARM Client Portal access, no relationship with the broker, and no contractual language that transfers refund rights. The four-year correction window under Customs Act Section 74 is wide open, but the buyer cannot use it.

Importer of Record Versus Buyer: CBSA Does Not Care About Your Purchase Terms

CBSA recognizes one party per import transaction: the entity named on the CAD as importer of record. If that entity is your Chinese, German, or Dutch supplier filing as a non-resident importer (NRI), CBSA’s entire compliance relationship runs through them and their designated resident broker. The fact that you paid the freight, arranged drayage through a Montreal sufferance warehouse, and own the goods after release does not change the duty liability or refund entitlement.

This is not an accounting quirk. It is a statutory structure. The NRI supplier is the declarant. Their broker submits the CAD. Their broker posts release prior to payment (RPP) bond if applicable. Their broker receives CBSA verification notices, AMPS penalty assessments, and any refund determinations. The Canadian buyer is functionally invisible to CBSA unless the purchase contract includes indemnity clauses that shift liability without transferring importer-of-record status.

Most buyers discover this gap only when money is on the table: a tariff line drops from 6.5% MFN to duty-free under an expanded trade agreement, or a supplier’s HS classification gets corrected from a higher-duty schedule to a lower one. At that point, the buyer’s finance team asks the broker to file a drawback claim, and the broker replies that they have no filing authority because they were never the broker of record.

Who Files the Correction, Who Gets the Check

Under CARM Phase 2 Release 3 (which went fully live in 2024), duty drawback and refund claims must be filed by the same party that submitted the original CAD, or by an entity granted explicit delegation in the CARM Client Portal. If your supplier’s shipping broker filed the entry, your broker cannot simply override it with a correction filing.

The workflow is:

• The original filer (supplier’s broker) submits a B2 adjustment declaration or a drawback claim through CARM.
• CBSA reviews the HS reclassification, origin documentation, or tariff schedule change.
• If approved, CBSA issues a refund to the importer of record listed on the original CAD.
• That entity is the NRI supplier, not the Canadian buyer.

The buyer’s only recourse is contractual: if the purchase order included a clause assigning all duty refunds, drawbacks, and preference claim benefits to the buyer, the supplier is obligated to remit the CBSA refund. If no such clause exists, the supplier keeps it. We have seen suppliers remit refunds as a goodwill gesture on long-term contracts, and we have seen suppliers ignore the request entirely. CBSA does not mediate commercial disputes.

The CARM Client Portal Access Problem

Even if your contract assigns refund rights, you still need someone with CARM Client Portal credentials to file the claim. If the supplier’s broker holds the original filing and has no ongoing engagement with you, they have no commercial incentive to process a correction that benefits a third party.

Your options:

1. Negotiate an amendment to the supplier relationship so future imports file under your Business Number as importer of record. This requires you to post your own RPP bond or financial security, engage a Canadian customs broker, and accept full AMPS liability for any origin or valuation errors.
2. Pay the supplier’s broker to file the correction on your behalf, with the supplier’s written authorization. This works only if the supplier agrees, and the broker may charge a project fee.
3. Accept that refunds tied to historical NRI entries are not recoverable, and tighten contract language for future shipments.

Most mid-market importers do not discover they need option 1 until after several months of NRI import history. By then, the sunk cost of unclaimed refunds makes the switch worth the administrative lift.

Tariff Refund Scenarios Where the Buyer Loses by Default

CUSMA origin retroactively proven. Supplier ships ex-works, files CAD with MFN duty at 6.5%, later provides a CUSMA certificate of origin that would have zeroed the duty. The supplier’s broker files a CUSMA preference claim correction. CBSA refunds the duty to the NRI supplier. Unless the contract assigns CUSMA savings to the buyer, the supplier pockets the spread.

HS classification corrected down. A CBSA verification or a post-clearance audit determines the goods should have entered under a lower-duty HS 6-digit code. The supplier’s broker files a correction. Refund goes to the NRI.

CETA expansion or tariff phase-down. A Canada-EU bilateral agreement accelerates a tariff phase-down schedule. Goods imported six months ago at 4% duty now qualify for duty-free treatment. The supplier’s broker files a drawback claim under the four-year window. The NRI captures the refund.

In each case, the Canadian buyer paid the landed cost including duty as part of the purchase price. The buyer has no direct claim to the refund unless the contract explicitly carved out that right.

How Purchase-Order Language Fixes This

If your sourcing model requires the supplier to act as importer of record, the purchase order or master service agreement must state:

• All duty drawback, refund, or preference claim benefits arising from imports under this agreement are assigned to [Canadian Buyer Entity Name].
• Supplier agrees to instruct its customs broker to file any CBSA corrections, adjustments, or drawback claims at Buyer’s written request, with refunds paid directly to Buyer or remitted within 30 days of receipt.
• Supplier’s broker will grant Buyer read-only CARM Client Portal access to CAD filings for verification and audit purposes.

Without these clauses, the default statutory rule governs: refunds flow to the importer of record. That is the supplier.

The Practical Call

If your supplier mix includes NRI filers and you have no contract language on refunds, you are leaving money on the table every time a tariff line shifts, an origin claim gets corrected, or a drawback opportunity surfaces. The four-year claim window is real, but it only helps the party with CARM filing access.

We file CAD corrections and drawback claims as part of routine compliance work. If you are the importer of record, we can recover what CBSA owes. If the supplier is the importer of record and your contract is silent, the best we can do is draft an amendment for your next shipment. Get in touch.

Frequently Asked Questions

What is a non-resident importer under CBSA rules?

A non-resident importer (NRI) is a foreign entity that imports goods into Canada but has no permanent establishment here. Per CBSA’s D1-7-1 memorandum, the NRI must appoint a resident agent or customs broker to transact on their behalf and post financial security.

How long do I have to claim duty drawback in Canada?

The Customs Act Section 74 allows duty drawback claims within four years of the original import date. Most brokers see claims filed within 12 to 18 months when tariff reclassifications or CUSMA origin corrections surface, but the statutory window is four years.

Who files the CAD when the supplier is importer of record?

The supplier’s designated shipping broker or the supplier themselves (if they have CARM Client Portal credentials and an RPP bond) file the Commercial Accounting Declaration. The Canadian buyer typically has no filing access unless named as importer of record or granted portal delegation.

Can a Canadian buyer claim a drawback if the NRI paid the duty?

No, unless the purchase contract explicitly assigns refund rights to the buyer. The party named as importer of record on the CAD holds the legal claim. If the NRI supplier paid duties and their broker filed, the buyer must negotiate contractually to recover any refund.

What happens if CUSMA origin is claimed incorrectly on an NRI shipment?

CBSA can assess AMPS penalties for false or unsupported origin claims, ranging from CAD 1,000 to CAD 25,000 depending on infraction level. The importer of record is liable, which means the NRI supplier, not the Canadian buyer, unless indemnity clauses shift responsibility.

Do I need a separate broker if my supplier already has one?

If you want visibility into CAD filings, release timing, or the ability to claim future refunds, yes. Relying solely on the supplier’s broker means you have no CARM Client Portal access and no direct line to CBSA if a verification notice arrives.

Can I switch from NRI to direct import mid-contract?

Yes, but it requires amending Incoterms, assigning a new importer-of-record entity, posting your own RPP bond or financial security, and ensuring your customs broker files future CADs under your Business Number. The supplier’s broker has no obligation to transfer historical filing data.
