The CBSA cargo-control document behind every highway shipment — how the A8A works, how to complete it, and where it still shows up alongside ACI eManifest.
The A8A is CBSA's cargo control document (CCD) — the highway carrier's cargo manifest. Each A8A carries a Cargo Control Number (CCN) that identifies the shipment to CBSA from the border through to release. For routine traffic the A8A's data is now transmitted electronically as an ACI eManifest, but the A8A itself — and its CCN — remains the underlying control document, and the paper form is still the official fallback when electronic filing is unavailable and the reference in specific in-bond and bonded-warehouse moves. Every carrier running Canada-bound freight should understand what the A8A is, how to complete it, and how its CCN ties into ACI.
The A8A is CBSA's cargo control document for highway shipments — the manifest that identifies what a truck is carrying, for whom, and where it will be released. Its defining feature is the Cargo Control Number (CCN): a unique number, built from the carrier's code plus a unique reference, that CBSA uses to track the shipment from the border to final release at a broker or sufferance warehouse.
Conceptually the A8A lists the carrier, the conveyance and crew, the port of arrival, and a cargo section with one line per shipment — Cargo Control Number, consignee, description, pieces, weight, and piece marks or container numbers. It is the paper ancestor of today's electronic ACI eManifest, and the two describe the same thing.
For most highway freight, CBSA now wants the manifest electronically as an ACI eManifest, transmitted at least one hour before the truck arrives at the border. ACI did not replace the *concept* of the A8A — it replaced the *paper channel*. The cargo control data and the CCN are the same; ACI just delivers them digitally and gets an automated acknowledgement back from CBSA.
That is why carriers still talk about 'the A8A' even when they file ACI: the CCN on your eManifest is the A8A cargo control number. Where the paper A8A genuinely comes back into play is fallback and specific bonded moves, below.
The paper A8A becomes the working document in three scenarios:
In all three, the A8A is the physical document that travels with the freight and carries the CCN CBSA will look up.
Filling in an A8A is mechanical once you know the fields. Working top to bottom:
The CCN is the field that matters most: it is how the broker's entry, CBSA's release, and your manifest all find each other.
Carriers often search for an 'A8A bond' — the connection is bonded freight. When goods arrive but are not released at the border (they move to a sufferance warehouse, or transit under customs control), the movement happens under the carrier's cargo control responsibility, tracked by the A8A's CCN. The related in-transit document for freight moving under bond between Canadian points is the A8B, the Canadian analogue of the US 7512 in-bond form.
If your operation moves freight to bonded warehouses or in-transit, the A8A/CCN discipline is what keeps those movements accounted for and closes them out cleanly with CBSA.
The most common A8A mistake is treating paper as a *substitute* for ACI when ACI is actually required — CBSA may accept the paper form at the booth but still issue an AMPS penalty for failure to submit advance commercial information. If ACI is the rule for your lane, the paper A8A is a fallback, not a licence to skip electronic filing.
The second is CCN format and reuse — an invented, reused, or malformed CCN will be rejected at entry filing time and can strand the shipment. The CCN follows the carrier-code-plus-unique-reference structure also used by the PARS barcode; keep them unique and well-formed.
BorderPro files your ACI eManifest electronically and, for fallback, generates a pre-filled A8A PDF from the same eManifest data — so in a CBSA outage you can print and present paperwork that matches what would have been filed electronically. The CCN, cargo lines, and consignee data carry directly from the dispatched shipment, which eliminates the re-keying errors paper fallback usually introduces.
The A8A is CBSA's cargo control document for highway shipments — the carrier's manifest. It identifies the carrier, conveyance, and cargo, and carries a Cargo Control Number (CCN) that CBSA uses to track the shipment from the border to release. For routine traffic its data is now filed electronically as an ACI eManifest.
The A8A number is the Cargo Control Number (CCN) — a unique identifier built from your four-character CBSA carrier code plus a unique reference. It ties your manifest, the broker's entry, and CBSA's release together. It must be unique per shipment; reused or malformed CCNs are rejected.
The A8A manifest is simply the A8A used as a cargo manifest — the list of shipments a highway carrier is bringing into Canada, one cargo line each, under one or more CCNs. In electronic form this is your ACI eManifest cargo data.
Yes. CBSA publishes the A8A form, and eManifest software (including BorderPro) can generate a filled A8A PDF on demand from your shipment data. Most carriers no longer keep paper pads on hand — generating a filled PDF when fallback is needed is the practical middle ground.
Yes. The A8A remains a recognised CBSA cargo control document. It is not the preferred channel for routine traffic — ACI eManifest is — but it is legally acceptable in fallback and specific in-bond/bonded scenarios.
A8A is the carrier's cargo control document (your manifest). A8B is the in-transit document used when freight moves under bond between Canadian points — the Canadian equivalent of a US 7512 in-bond form.
The A8A itself is a cargo control document, not a bond. Bonded-carrier and in-transit privileges (moving freight to a sufferance warehouse or under customs control) require the appropriate CBSA bonded-carrier authorisation; the A8A/CCN is how those movements are tracked. Confirm your bonded-carrier status with CBSA.
Yes — and it is good practice in marginal-connectivity scenarios. If ACI has been accepted electronically, the paper A8A is redundant; if ACI transmission fails at the last minute, the paper A8A is your fallback.
