How a packing list can make or break your shipment

Written by Cole Marketing | Mar 9, 2026 1:00:04 PM
If the packing list does not match what is shipped, the CBSA may hold the shipment, delay clearance, and, in cases of non-compliance with reporting requirements, assess AMPS penalties.

A packing list is a key document in the shipping process, and every detail on it matters.

When packing list details do not align with the rest of your shipping documents, your shipment may be delayed.

In this article, we break down what a packing list should typically include, five common mistakes that can cause delays, and five tips to get your packing list right.

What’s in a packing list?

A packing list summarizes what’s in a shipment and how it’s packed. It supports customs clearance and inspections.

The Canada Border Services Agency (CBSA) may use the packing list to verify shipment contents, warehouses may use it when receiving goods, and carriers or insurers may require it to support claims for loss or damage during transit.

There isn’t a specific template or format, but a packing list must typically include:

    • Shipper and consignee details
    • Reference numbers (invoice or purchase order numbers)
    • Item descriptions
    • Quantities and unit of measure
    • Net and gross weight
    • Packaging details
    • Dimensions per package
    • Marks and identifiers

If all packing details are included on the invoice, a separate packing list is not required.

Other details may be helpful, such as HS codes, special handling instructions, or hazardous goods information.

5 common packing list mistakes

Here are common packing list mistakes that may cause delays and, in some cases, increase your exposure to penalties under CBSA’s Administrative Monetary Penalty System (AMPS):

1) Generic descriptions

If the CBSA cannot match the declared description to the contents because it’s too vague or generic, the goods may be held until the shipment is clarified.

2) Weight discrepancies

If the weights on the packing list do not match the bill of lading or commercial invoice, the shipment may be flagged for review.

3) Mismatches with the invoice

If descriptions or quantities do not match the commercial invoice, the CBSA may question the declared value or classification details, and clearance may be delayed until you confirm the correct shipment details.

4) Unclear package details

If you don’t show the details of how items are distributed across cartons or pallets, receiving a shipment may be difficult, and disputes over shortages or damage become harder to resolve.

5) Incorrect or inconsistent units

If you mix units, such as boxes and pieces, or kilograms and pounds, this can create confusion and raise questions about the accuracy of the quantities.

5 tips to get your packing list right

Your packing list should be clear enough for everyone to understand and use. Here are five best practices to consider:

1) Use clear, specific descriptions

Write descriptions that anyone handling the shipment can understand. Use the same wording as on the commercial invoice and add details as needed.

2) Align details on all documents

Before the shipment moves, cross-check your:

    • Commercial invoice (what was sold)
    • Packing list (what was packed)
    • Bill of lading (what the carrier received)

Make sure the details align across all three documents.

3) Make the packing easy to confirm

If there are multiple cartons or pallets, number them (for example, 1 of 10) and explain what is in each. This simplifies receiving and makes shortages or damage easier to confirm.

4) Keep units and totals clear

Use the same units across all documents. Do not mix pieces and boxes without explaining the pack count. Do not switch between kilograms and pounds. And make sure totals add up.

5) Flag shipments that need more detail

If the shipment is mixed, high-value, or likely to be examined, your freight forwarder or customs broker may need additional details in advance.
