Customs Compliance
ACI eManifest requires carriers to submit cargo information to CBSA before arrival in Canada. This guide explains acceptable vs unacceptable cargo descriptions and how to stay compliant.
ACI eManifest is CBSA's pre-arrival cargo reporting program. Carriers must submit electronic cargo data before a shipment arrives at a Canadian border. The cargo description must be specific enough for CBSA to identify the goods — vague terms like "general merchandise" or "household goods" are not acceptable and can result in penalties or border delays.

ACI eManifest
CBSA's Advance Commercial Information (ACI) program requires carriers to electronically transmit cargo and conveyance information before a shipment arrives at a Canadian port of entry. This allows CBSA to assess risk and identify shipments requiring examination before they arrive.
The carrier (trucking company, rail operator, or airline) is responsible for submitting conveyance and cargo information. Importers and their customs brokers must ensure the cargo description provided to the carrier is accurate and sufficiently specific.
Cargo Descriptions
CBSA requires that cargo descriptions identify the actual goods. The examples below are drawn from CBSA guidance on ACI compliance.

Pre-Arrival Risk Assessment
ACI eManifest is one part of a broader family of pre-arrival programs CBSA uses to assess cargo before it reaches the border, spanning ocean, air, highway, and rail shipments.
Rather than reviewing shipments only after they arrive, CBSA receives electronic cargo and conveyance data in advance so officers can evaluate risk, flag freight that may warrant closer inspection, and let well-documented shipments move through processing more smoothly. The same underlying principle — advance electronic data in place of paper documents presented on arrival — applies across ocean, air, highway, and rail movements, though each mode has its own reporting stream and its own CBSA system requirements.
How far in advance data needs to reach CBSA is not the same for every mode. Ocean shipments generally call for the earliest submission, since cargo data is assessed while the vessel is still well out at sea. Air cargo is typically transmitted around departure, reflecting much shorter transit times. Highway shipments crossing by truck usually work on the shortest window of all, with data needed shortly before the truck reaches the border. Rail carriers follow their own advance-notice expectations tied to typical transit patterns. Across every mode, the general rule holds: submitting complete, accurate data as early as reasonably possible reduces the risk of a hold at the border, while last-minute or incomplete submissions carry a materially higher risk of delay.
Compliance Risk
Gaps in eManifest data don't just create paperwork problems — they can affect whether a shipment clears on schedule.
When eManifest data is missing, vague, or submitted too close to arrival, CBSA may not have enough information to complete its risk assessment before the shipment reaches the border. The cargo can then be held for further review, referred for documentary or physical examination, or simply delayed while the carrier or importer supplies the missing information. For time-sensitive freight, even a short hold can disrupt delivery appointments or downstream production schedules.
Beyond delay at the border, CBSA treats eManifest accuracy and timeliness as an ongoing compliance matter, and carriers with a pattern of late, missing, or unreliable submissions can face escalated scrutiny and other enforcement action on future shipments. Because the carrier carries the legal filing obligation, importers and forwarders who supply vague or last-minute cargo information effectively pass that compliance risk on to their carrier partners — one reason accurate, early data matters to everyone in the supply chain, not only the party who submits the filing.
Working With Eztrans
The legal obligation to file eManifest data rests with the carrier, not the importer or the freight forwarder. In practice, though, getting that data right depends on everyone earlier in the chain supplying accurate, specific information in time. Eztrans works with our customs brokerage partner to gather the underlying shipment details — commercial invoice information, product descriptions, and conveyance details — as early as possible in the shipping process, well before the carrier's own filing needs to happen. We review cargo descriptions against CBSA's specificity standards before they are passed along, so vague or generic wording gets corrected before it becomes a border-side problem rather than after. For importers, this means you don't have to track mode-specific filing expectations, monitor CBSA system requirements, or interpret compliance notices yourself — our team and our brokerage partner manage that coordination as part of handling your shipment, so eManifest is one less thing you need to manage directly.
FAQ
Clear answers for Canadian importers evaluating freight forwarding, China–Canada shipping, and integrated logistics options.
ACI eManifest (Advance Commercial Information) is CBSA's electronic pre-arrival reporting program. Carriers and freight forwarders must submit cargo and conveyance information to CBSA before a shipment arrives at a Canadian border. This allows CBSA to assess risk before goods arrive.
The carrier (truck, rail, or air) is responsible for submitting the conveyance and cargo information. Freight forwarders and importers must ensure their cargo details — particularly the cargo description — are accurate and submitted on time.
An acceptable cargo description is specific enough for CBSA to identify the goods. It must describe the actual product — for example, 'wooden dining chairs' rather than 'furniture'. Vague terms like 'general merchandise', 'household goods', or 'various items' are not acceptable.
CBSA can issue Administrative Monetary Penalties (AMPs) for late, inaccurate, or missing e-manifest submissions. Cargo may also be held at the border pending corrected documentation, causing delays and additional costs.
