Setting the Foundation: Your Obligations as an Importer

Importing commercial goods into Canada is more than just shipping a product across the border—it is a legal transaction governed by the Customs Act and the Customs Tariff. The core principle is that the importer of record (you) is legally responsible for the correctness of all import declarations, even when using a licensed Customs Broker.

Before your first shipment even leaves the foreign seller's dock, you must address three foundational requirements.

1. The Business Number (BN9) and RM Account

Every commercial importer in Canada must possess an Import/Export Program Account.

BN9: This is your 9-digit Business Number issued by the Canada Revenue Agency (CRA).
RM Account: This is the specific 4-digit reference number associated with your import/export activities (e.g., 123456789RM0001).

CARM Note: The CBSA Assessment and Revenue Management (CARM) system is now the official system of record. New importers typically register for their RM account directly through the CARM Client Portal.

2. The Three Pillars of Customs Compliance

The duty and tax liability for your goods is calculated based on three essential data elements, often called the "Three Pillars." Getting any of these wrong can result in costly penalties (AMPS) or future compliance verifications.

Pillar	Description	Key Reference
1. Classification	The 10-digit Tariff Classification Number used to identify the goods in the Customs Tariff.	Harmonized System (HS) & General Rules of Interpretation (GRIs)
2. Valuation	The Value for Duty (VFD), typically based on the Transaction Value (price paid or payable), plus any mandatory additions (e.g., freight, assists, royalties).	Customs Act (Section 48 to 53)
3. Origin	The country of manufacture, which determines the applicable Tariff Treatment (e.g., Most-Favoured-Nation, or a preferential rate like CUSMA).	Rules of Origin for the applicable trade agreement.

3. Regulatory Controls (OGD)

You must verify if your goods are controlled, regulated, or prohibited by any Other Government Departments (OGD), such as the Canadian Food Inspection Agency (CFIA), Transport Canada, or Global Affairs Canada (for import permits). A common error is assuming goods can be imported without the proper OGD permits or documentation.

The Core Import Transaction: Release and Accounting

Once the preparatory steps are complete, the physical import process is broken down into two main phases:

Phase 1: Release of Goods (eManifest/Reporting)

The carrier must transmit advance commercial information to the CBSA via an electronic manifest (eManifest) prior to the goods arriving at the border.

Reporting: The carrier submits the Cargo Control Document (CCD) data to the CBSA, officially reporting the goods upon arrival. This places the goods "in bond."
Release Request: You (or your Customs Broker) submit a release request to the CBSA using a 14-digit Transaction Number associated with the cargo.
- PAPS/PARS: For highway carriers, this is typically done through the Pre-arrival Review System (PARS).
CBSA Decision: The CBSA reviews the release data. Once satisfied, a Release Notification is transmitted to the carrier, allowing the physical goods to be moved from CBSA custody (often to your facilities).

Phase 2: Accounting and Payment (CAD / Statement of Account)

The release of goods is only the first step. You have a maximum of five business days after the date of release to provide final accounting and payment of duties and taxes.

The CAD: The primary accounting document (Commercial Accounting Document or its electronic equivalent). This document consolidates all the "Three Pillars" data (classification, valuation, origin) and calculates the duties, GST/HST, and other taxes payable.
Payment: Importers typically pay their total monthly liability via the Statement of Account (SOA) through the CARM system.

Key Takeaway: Release (getting the goods) and Accounting (paying the duties) are legally distinct events. The Importer remains liable for the accounting declaration long after the goods have been physically received.

Post-Release Obligations (The Importance of Compliance)

Compliance doesn't end once the goods are released.

Record Keeping: Importers are legally required to keep all records related to the importation (commercial invoices, shipping documents, proof of origin, contracts, etc.) for six years following the date of importation.
Self-Correction: If you discover an error in your CAD accounting—even if it's revenue neutral or the CBSA didn't find it—you have a four-year period from the date of accounting to submit a voluntary correction (CAD version adjustment) to avoid potential penalties.
Trade Compliance Verifications: The CBSA conducts regular verifications (audits) to ensure compliance with the Three Pillars. Strong record-keeping and a proactive compliance program are your best defense.
