A packing list for export is the document that itemizes every package in a shipment: what is inside each box, crate or pallet, how much it weighs, how big it is and how it is marked. Freight forwarders use it to work out weight and freight costs, and customs officers at both ends use it to check the cargo against what was declared.
It looks like a simple form, and that is exactly why it causes trouble. A packing list that disagrees with the commercial invoice or the bill of lading by a single carton can stall a bank payment or flag a container for inspection. This guide walks through the format field by field, shows a filled sample you can copy, and covers the mistakes that most often hold cargo at the port.
What a Packing List for Export Does
The packing list answers one question for everyone who touches the shipment: what exactly is in each package? According to the International Trade Administration (ITA), it itemizes the contents of each box or pallet, including weights, measurements and detailed lists of the goods. A copy should travel inside the package, and one can be attached to the outside as well.
Three groups rely on it. The forwarder uses it to determine total weight and volume, which drives the freight quote and the booking. The carrier and terminal need the weights to plan how the cargo is stowed. Customs officials in the export and import country use it to check a specific carton without opening the whole consignment.
An export packing list is more detailed than the slip you find in a domestic parcel. The U.S. Commercial Service guide to the export packing list notes that it shows the net, tare and gross weight of each package, its measurements in both U.S. and metric units, the type of package and its markings.
Packing List vs Commercial Invoice
Exporters often treat the two documents as interchangeable. They are not. The commercial invoice is the bill from seller to buyer: it states what was sold and what the buyer pays, and customs uses it to assess duty. The packing list says nothing about price. It describes the physical shipment.
The ITA is explicit on this point in its overview of common export documents: a packing list may serve as a conforming document, but it is not a substitute for a commercial invoice. Because customs officers use the packing list to check the cargo, the commercial invoice should reflect the information shown on it.
In practice this means the two are prepared together, from the same order data. Quantities, descriptions and the invoice number should match line for line. If you are building both from scratch, our guide to commercial invoice fields covers the pricing side that the packing list leaves out.
The Fields an Export Packing List Needs
The ITA lists the core content of an export packing list: seller, buyer, shipper, invoice number, date of shipment, mode of transport, carrier, and an itemized breakdown of quantity, description, package type, number of packages, total net and gross weight in kilograms, package marks and dimensions. Grouped the way most forms lay them out, that gives four blocks.
Parties and references
The header names the exporter or seller, the buyer, and the consignee if it differs from the buyer, with full addresses. It also carries the references that tie the document to the rest of the file: the commercial invoice number, the purchase order number, the date, and the letter of credit number if payment runs through one.
Shipment details
This block records how and where the goods travel: mode of transport, carrier, vessel name and voyage if known, port of loading, port of discharge and final destination. Many exporters add the Incoterm here as well, so the forwarder can see at a glance who handles which leg.
Package lines
Each line describes one package or a run of identical packages. It gives the shipping marks and package numbers, the type of package, how many there are, a plain description of the goods, the quantity of units inside, and the weight and dimensions of each package. Adding the HS code to each line costs nothing and helps customs match the packing list to the declaration.
Totals
The bottom of the list adds up the total number of packages, the total net weight, the total gross weight and the total volume in cubic meters. These are the numbers everyone downstream compares, so they deserve the most care.
A Sample Export Packing List Format
Here is a filled example for a fictional shipment of oak furniture from a manufacturer to a retailer, sent as one sea freight consignment. The header would carry the parties, invoice number, vessel and ports described above. The body looks like this:
| Marks and numbers | Packages | Description (HS 9403.60) | Net kg | Gross kg | Size per package |
|---|---|---|---|---|---|
| NRD/ROT/PO4471, 1-40 | 40 cartons | Oak dining table tops, 1 pc per carton | 1,120 | 1,260 | 180 x 95 x 12 cm |
| NRD/ROT/PO4471, 41-80 | 40 cartons | Oak table leg sets, 1 set of 4 legs per carton | 360 | 408 | 80 x 30 x 25 cm |
| NRD/ROT/PO4471, 81-82 | 2 wooden crates | Oak benches, 6 pcs per crate | 192 | 236 | 190 x 60 x 70 cm |
| Total | 82 packages | 92 pieces | 1,672 | 1,904 | 12.20 m3 |
A few details make this sample work. The marks repeat the buyer code, the destination port and the order number, so any carton separated from the rest can still be identified. Package numbers run continuously from 1 to 82 with no gaps, which lets anyone confirm nothing is missing by counting.
The volume total comes from multiplying each package's length, width and height, then multiplying by the number of packages: 8.21 m3 for the table tops, 2.40 m3 for the leg sets and 1.60 m3 for the crates. If you need a refresher on the arithmetic, this walkthrough on how to calculate CBM covers it in centimeters and inches.
Net, Tare and Gross Weight on a Packing List
Three weights appear on a well prepared list, and mixing them up is one of the most common errors. Net weight is the goods alone. Tare weight is the packaging: the carton, crate, pallet or drum. Gross weight is the two added together, and it is what the forwarder and carrier care about most.
Gross weight per package should always equal net weight plus tare, and the line totals should add up to the grand total. It sounds obvious, yet a spreadsheet formula copied one row too far is enough to make the totals disagree with the bill of lading.
Units matter too. The export.gov guidance calls for both U.S. and metric measurements, while the ITA overview asks for total weights in kilograms. Stating kilograms and centimeters first, with pounds and inches alongside where your buyer expects them, keeps the list readable everywhere.
Packing List Weights and the Container VGM
For containerized sea freight there is a second weight that the packing list feeds into: the verified gross mass, or VGM. Under SOLAS regulation VI/2, as the IMO explains, the shipper must provide the verified gross mass of a packed container before it is loaded, and a container without one is not loaded.
The VGM is not the gross weight on your packing list. It covers the whole packed container: the cargo, the pallets, the dunnage and securing material, plus the tare of the container itself. The IMO allows two methods: weigh the packed container, or weigh all packages and cargo items, including pallets, dunnage and securing material, and add the container tare, using a certified method approved by the competent authority where the container was packed.
If you use the second method, the packing list becomes your starting point. Accurate gross weights per package, plus the weight of anything used to brace the load, plus the tare stamped on the container, give the figure you declare. Errors on the packing list therefore travel straight into a safety declaration.
Packing Lists Under a Letter of Credit
When payment runs through a documentary credit, the packing list stops being a logistics form and becomes a document a bank examines before it pays. The ICC's banking practice rules set out how banks treat it in paragraphs M1 to M6 of ISBP 745.
Three of those rules shape how you prepare the list. A document satisfies the requirement as long as it is titled as the credit asks, has a similar title or no title, and contains information about the packing of the goods. If the credit names who must issue the packing list, that entity has to issue it. And banks examine only the totals: total quantities, weights, measurements and packages, checking that none of them conflicts with the credit or with any other required document.
That last rule is why totals deserve the most attention. A bank will not query a line description that reads slightly differently from the invoice, but it will refuse a presentation where the packing list says 82 packages and the bill of lading says 80.
Refusals are not rare. An ICC Banking Commission briefing on discrepancy rates estimates that 65 to 80 percent of documents presented under documentary credits worldwide are refused on first presentation. Among the common causes it lists are conflicting data between documents and goods descriptions that do not match the credit.
Common Packing List Mistakes That Delay Cargo
Most packing list problems come from the same handful of habits. These are the ones worth checking before the document leaves your office:
- Totals that disagree with other documents: Package count, gross weight and volume must match the commercial invoice, the bill of lading and the VGM declaration.
- Vague descriptions: "Furniture parts" tells customs nothing. Describe what the item is and what it is made of, and add the HS code.
- Gaps in package numbering: If cartons are numbered 1 to 40 and then 45 to 82, someone will ask where 41 to 44 went.
- Marks on the list that differ from marks on the boxes: An inspector compares the two first, so print the list from the same data as the labels.
- No copy with the cargo: The ITA recommends a copy inside the package, which helps when a carton is opened at destination.
- Last minute changes not carried through: If a pallet is added or removed at loading, every document has to be reissued, not only the one the warehouse holds.
A good discipline is to produce the packing list, the commercial invoice and the shipping instructions from one source, such as the order record in your ERP or one master spreadsheet, rather than typing each separately.
How the Packing List Fits the Rest of the Export File
The packing list sits at the center of the export file. The forwarder books space from it. The commercial invoice mirrors its quantities. The bill of lading repeats its package count, gross weight and marks. The VGM builds on its weights, and under a letter of credit the bank compares its totals with everything else.
Once the documents are filed and the container is on board, attention shifts to where the goods are. Carrier portals report container milestones, which is not the same as watching the ship itself. Primo Nautic lets you look up the carrying vessel by name, MMSI or IMO number and follow its live position on a map.
With the Cargo Shipment tracking purpose selected, Primo Nautic gives precise, logistics-focused updates, compares the captain's reported ETA with its own calculated ETA, and sends a delay notification when the arrival time slips. That gives you an early warning to pass on to your consignee instead of a surprise at the terminal.
Conclusion
A packing list for export is a short document with a long reach. It tells the forwarder what to book, the carrier what to stow, customs what to check and, under a letter of credit, the bank what to compare.
Get the fundamentals right and most problems disappear: list every package with its marks, type, contents and dimensions; state net, tare and gross weight that actually add up; keep package numbers continuous; and make sure the totals match the commercial invoice, the bill of lading and the VGM. Prepared from the same data as the rest of the export file, the packing list stops being a source of delays and becomes the document that keeps the shipment moving.
