Importer of Record in Canada: Who Holds the Liability and Why It Matters

Brands entering Canada often ask their fulfillment partner to handle the import paperwork. That request raises a bigger question: who will serve as Importer of Record? This designation carries legal and financial liability that extends far beyond paperwork. The Importer of Record (IOR) in Canada is not simply an administrative field on a customs form. It is a legally binding designation that determines who bears responsibility for duties, taxes, penalties, and compliance with product-specific regulations. Getting this wrong can expose your brand, your fulfillment partner, or both to significant financial and legal risk.

For D2C brands entering the Canadian market, understanding IOR obligations is foundational to building a compliant, sustainable operation. This article explains who can legally serve as IOR, what that designation means in practice, why fulfillment providers cannot casually accept this role, and how to structure arrangements that protect your business while enabling efficient cross-border operations.

Who This Article Is For

This article is written for operations managers, supply chain directors, and founders at international D2C brands who are actively researching Canadian market entry or currently onboarding with a fulfillment partner. It is also relevant for 3PL operators and customs brokers seeking clarity on liability boundaries and proper role delineation.

This article is not a substitute for legal advice. Brands with complex import structures, regulated products, or significant compliance exposure should consult a licensed customs broker and legal counsel familiar with Canadian trade law.

Legal Definition of Importer of Record in Canada

The Canada Border Services Agency (CBSA) defines the Importer of Record as the party whose business number appears on the customs accounting documents at the time goods are accounted for. Under Section 17(3) of the Customs Act, this entity is jointly and severally liable with the actual importer and the owner of the goods for all duties and taxes, including amounts reassessed after release.

Three terms require careful distinction:

• Importer: The person who causes goods to be imported into Canada, regardless of whose name appears on customs documents.
• Owner: The person who holds title to the goods at the time of release.
• Importer of Record: The person whose 15-character business number (BN15) is identified on the Commercial Accounting Declaration (CAD).

“Jointly and severally liable” means CBSA can pursue any one of these parties for the entire customs debt. If CBSA reassesses $200,000 in duties three years after import, it does not have to split the bill evenly among the IOR, importer, and owner. It can collect the full amount from whichever party is most accessible. Contractual indemnities between parties help allocate costs but cannot prevent CBSA from enforcing statutory liability.

The business number itself comprises two components: a 9-digit business number (BN9) and a 6-character CBSA import program account made of the RM identifier and a 4-digit reference (for example, RM0001). Together they form the 15-character BN15 that identifies the IOR on each declaration.

What the IOR Is Legally Responsible For

The IOR’s obligations extend far beyond paying duties at the border. Understanding this scope is essential before accepting or assigning IOR designation.

Financial Obligations

• Customs duties: Amounts calculated based on tariff classification, value for duty, and country of origin.
• Import GST/HST: the GST (or the federal part of the HST) is collected at the time of importation. The CRA page on GST/HST on imports and exports explains how the provincial part of the HST applies to imported goods.
• Excise taxes: Where applicable to specific product categories.
• Anti-dumping and countervailing duties: If the product is subject to Special Import Measures Act (SIMA) provisions.
• Reassessed amounts: CBSA can reassess duties and taxes up to four years after import, and the IOR remains liable for any shortfall discovered during audits.

Compliance Obligations

• Accurate declarations: Correct tariff classification, proper valuation methodology, and substantiated country of origin.
• Product admissibility: Confirming that goods meet all regulatory requirements before shipment, including permits, licences, and labelling standards.
• Record retention: Maintaining customs records for six years after importation, including invoices, origin documentation, and broker instructions.
• Corrections: Reporting errors within 90 days when the importer has reason to believe that classification, value, or origin was incorrect.

Regulated Product Requirements

For natural health products, food, and cosmetics, the IOR must also ensure compliance with Health Canada and CFIA requirements. This includes verifying that products hold appropriate licences (such as a Natural Product Number for NHPs), meet labelling requirements, and that the importer holds necessary site licences where applicable. The CBSA Memorandum D17-2-5 on duty liability provides detailed guidance on how these obligations interact with customs accounting.

Who Can Legally Serve as Importer of Record

Not every party involved in cross-border trade can serve as IOR. Eligible parties include:

1. The owner or purchaser of the goods who holds a Canadian business number or registers as a non-resident importer.
2. The consignee in Canada who takes delivery and has registered with CBSA.
3. A designated non-resident importer (NRI) who has obtained a BN9 from CRA, registered in CARM, and enrolled in the import program.

Common Misconceptions

Many brands assume their freight forwarder, carrier, or customs broker can “just be” the IOR. This misunderstands the legal structure of these relationships:

• Customs brokers act as agents, filing declarations using the client’s BN15. A broker using the client’s business number is not the IOR. A broker can only become IOR if its own BN15 is placed on the accounting documents, which creates a fundamentally different risk profile.
• Freight forwarders and carriers coordinate logistics but do not typically have the legal structure to assume IOR liability. Moving boxes does not equal owning import obligations.
• Fulfillment providers store inventory and ship orders but do not become the IOR merely by handling freight or receiving goods into their warehouse.

The critical distinction: an entity only becomes IOR when its own BN15 appears on the Commercial Accounting Declaration. Everything else is agency or service provision.

Why 3PLs Should Not Casually Accept IOR Designation

This question often comes up during onboarding. When a brand asks a fulfillment provider to serve as IOR, they are asking that provider to assume full financial liability for duties, taxes, penalties, and compliance violations on products they do not own and business decisions they do not control.

Where the Risk Comes From

Consider the scenarios where this creates significant exposure:

• Product misclassification: The brand believes their product qualifies for a lower duty rate based on composition or use. If CBSA disagrees, reassessed duties fall on the IOR.
• Undeclared ingredients: A natural health product contains an ingredient requiring additional licensing that the brand failed to disclose. The IOR faces compliance violations and potential product seizure.
• Valuation disputes: The brand provides invoices that do not reflect the true transaction value, including assists, royalties, or related-party adjustments. Duty recalculations become the IOR’s liability.
• Post-clearance audits: CBSA audits transactions three years later and finds systematic errors across thousands of entries. The IOR is on the hook for the entire reassessment.

The Four-Year Exposure Window

CBSA can reassess duties and taxes up to four years after accounting. A single SKU-master error, multiplied across four years of high-volume orders, can create substantial liability. A fulfillment provider has no visibility into supplier price changes, ingredient modifications, or sourcing decisions that affect customs liability. Yet as IOR, they would bear responsibility for those decisions.

Aligning Liability with Control

The party who makes product decisions, controls supplier relationships, and owns the inventory is usually the appropriate party to bear import liability. Our customs brokerage support connects brands with licensed customs brokers, so the import structure can be set up correctly before inventory ships.

Non-Resident Importer Arrangements Explained

For international brands without a Canadian entity, the non-resident importer (NRI) structure provides a compliant path to IOR designation.

How NRI Works Operationally

1. BN9 registration: The foreign brand obtains a 9-digit business number from the Canada Revenue Agency.
2. CARM enrolment: The brand registers in the CARM registration for importers system and sets up its import program account.
3. Broker delegation: The brand delegates authority to a licensed customs broker who clears goods using the brand’s BN15.
4. Security posting: For Release Prior to Payment (RPP) privileges, the brand posts financial security based on its highest monthly accounts receivable with CBSA in the previous 12 months. Under CBSA’s RPP rules, a written security agreement must cover at least 50% of that amount, with a minimum of $5,000, while a security deposit must cover 100%.

Under this structure, the foreign brand remains the IOR and maintains full liability while goods are cleared in their name. The broker acts as agent, and the fulfillment provider handles logistics without assuming customs exposure.

When NRI Makes Sense

• Established brands with compliance infrastructure and the capacity to manage Canadian regulatory requirements.
• Regulated products (NHPs, food, cosmetics) where the brand must hold specific licences and maintain product oversight.
• Delivered-duty-paid (DDP) selling models where the brand controls pricing and customer experience.
• Brands planning significant Canadian market investment who want direct visibility into customs costs and compliance status.

When Canadian Entity IOR Is Preferable

• Brands working with a Canadian distributor who takes title to inventory.
• Operations where a Canadian partner has existing compliance infrastructure and assumes commercial risk.
• B2B arrangements where the Canadian customer will use or resell the products under their own import structure.

Timeline and Documentation

NRI registration is not instantaneous. Plan for several weeks to complete BN9 registration, CARM enrolment, broker delegation, and security posting. Required documentation includes proof of business registration in the home country, authorized representative information, and for regulated products, evidence of product licensing and compliance status. Our step-by-step guide to importing into Canada provides detailed onboarding timelines.

IOR Considerations for Specific Scenarios

Amazon FBA Canada

A common question: “Can Amazon serve as my IOR for FBA inventory?” The answer is no. When you ship inventory to Amazon’s Canadian fulfillment centres, you (or your designated NRI structure) are the importer. Amazon provides storage and fulfillment services but does not assume customs liability for seller inventory. Brands must either register as NRI or work with a Canadian entity who takes title before import.

Shopify Cross-Border Fulfillment

Shopify provides technology infrastructure for cross-border sales but does not serve as IOR. Brands selling through Shopify to Canadian customers must determine their import structure: direct-to-consumer shipments with the customer as importer (DAP), bulk inventory import with the brand as NRI, or sales through a Canadian entity who imports and fulfills domestically.

Regulated Product Categories

For natural health products, food, and cosmetics, IOR designation carries additional weight. The customs IOR and the regulated-product importer may be different legal designations under different statutes. A customs broker might clear goods as IOR while the brand remains the Health Canada importer of record for NHP compliance purposes. Both obligations must be explicitly mapped and assigned.

Low-Value Shipments

The Courier Low-Value Shipment (CLVS) Program applies to shipments valued at CAD $3,300 or less. While this provides simplified clearance procedures, it does not eliminate IOR requirements. Someone’s BN15 still appears on the declaration. Regulated products generally cannot use CLVS processing regardless of value.

Decision Framework for IOR Arrangements

Non-Resident Importer (Brand as IOR)

• Best for: Established international brands with compliance infrastructure.
• Advantages: Direct control over customs costs and compliance; supports DDP pricing models; maintains brand oversight of regulated products.
• Considerations: Requires BN registration, CARM enrolment, security posting, and ongoing compliance management.

Canadian Distributor or Entity as IOR

• Best for: Brands working with established Canadian partners.
• Advantages: Partner handles import obligations; leverages existing compliance infrastructure; simplifies cross-border accounting.
• Considerations: Requires a trusted partner relationship; brand loses direct visibility into duty costs; must negotiate pricing that accounts for import expenses.

Customer as IOR (B2B DAP)

• Best for: Business-to-business sales where the customer handles the import.
• Advantages: Transfers import liability to the customer; appropriate for wholesale transactions.
• Considerations: Not suitable for B2C; creates an unpredictable customer experience; the customer must have import capability.

How to Structure IOR Arrangements with Your Fulfillment Partner

The IOR conversation should happen early in the onboarding process, not when the first container is ready to ship. Here is what to prepare and what to ask:

Information to Gather Before Onboarding

• Current customs classification (HS codes) for all SKUs.
• Country of manufacture and any preferential origin claims.
• Product composition, ingredients, and any regulated product licences (NPN, SFC licence, cosmetic notifications).
• Valuation methodology and any related-party transaction considerations.
• Existing business number registration or NRI application status.

Questions to Ask During 3PL Evaluation

1. Does the fulfillment provider offer IOR services, and under what circumstances?
2. How does the provider coordinate with customs brokers for compliant clearance?
3. What product data does the provider require for inbound inventory receiving?
4. How are duties and brokerage fees invoiced and reconciled?
5. What record retention and audit support does the provider offer?

Agreeing on Roles Before the First Shipment

Clear boundaries work best when they are settled before inventory moves: who holds the IOR designation and CARM registration, which licensed customs broker files the entries, and how entry records link to inventory.

Moving Forward with Compliant Canadian Market Entry

The Importer of Record designation is not an administrative convenience. It is a legal commitment with financial and compliance consequences that can extend years beyond the original import. Getting this right protects your brand, maintains healthy relationships with fulfillment partners, and builds the foundation for sustainable Canadian operations.

For brands evaluating Canadian market entry, we recommend:

1. Determine your preferred IOR structure early, before logistics planning begins.
2. Begin BN registration and CARM enrolment well in advance of your first shipment.
3. Engage a licensed customs broker who understands your product category.
4. Ensure your fulfillment partner understands their role boundaries and yours.
5. Maintain complete documentation linking customs entries to inventory, orders, and product specifications.

We welcome conversations with brands who want to understand how IOR arrangements integrate with fulfillment operations. Clear boundaries, properly structured, enable efficient operations while protecting everyone involved.
