What this decision should produce
Final packing data connects the physical shipment to freight booking, customs documents, receiving, and landed-cost records.
Before approving the packing list, reconcile three independent totals: sellable units, physical cartons or pallets, and shipment weight or volume. The quantity by line item should add to the order total; units per carton should reproduce the carton count; and carton dimensions, net weight, and gross weight should be plausible when compared with the packed product. Ask the supplier to explain partial cartons, mixed cartons, accessories, spare parts, and free-of-charge items. Receiving teams and customs brokers need the same final packing facts, not separate versions prepared for different audiences.
Identify the parties and shipment reference
Ask for the shipper, consignee, purchase-order and invoice references, packing-list number and date, destination, and shipment method. Names and addresses should match the commercial and transport documents where required. If a trading company, factory, or separate exporter performs a different role, clarify which entity appears on each document.
Use stable product names, models, SKUs, and order references. The receiving team should be able to connect every packing-list line to the purchase order and expected inventory without guessing from a broad description such as accessories or samples.
Record how every SKU is packed
For each product, list carton numbers or ranges, carton quantity, units per carton, and total units. Mixed cartons should identify the exact SKU and quantity split. If serial numbers, batch codes, expiry dates, or lot references matter, include them or attach a controlled schedule.
Ask whether the figures are estimates or final packed quantities. Preliminary data is useful for freight planning, but the final packing list should be based on completed packing and reconciled against production and inspection records.
Collect weight, dimensions, CBM, and marks
Request net weight, gross weight, outer-carton length, width, height, unit of measure, and carton count. Calculate or verify CBM from outer dimensions and quantity. When cartons differ, list each size group separately instead of using one average that may distort the booking.
Include shipping marks, side marks, carton labels, pallet count, pallet dimensions, and pallet gross weight where applicable. Photograph a finished carton label and mark before shipment. Freight, warehouse, and customs teams rely on consistent package identification.
Reconcile the final document
Check total units against the PO and commercial invoice, total cartons against the booking, gross weight against the transport instruction, and CBM against the forwarder quote. Investigate differences rather than adjusting one document to make the totals look neat. The reason may be extra samples, short shipment, replacement goods, packaging change, or data entry error.
Keep the final approved file with the shipment record and send it to the broker, forwarder, warehouse, or buyer contacts who need it. A packing list describes physical packing; it does not replace the commercial invoice or declare customs value.
How the decision works in practice
A supplier packs two SKUs in 24 cartons. Cartons 1-16 contain 50 units of SKU A; cartons 17-24 contain 25 units of SKU B. The final list records dimensions and gross weight for each carton group, total net and gross weight, 1.42 CBM, shipping marks, and origin. The buyer finds that the invoice lists 1,050 units while the packing list totals 1,000, allowing the documents to be corrected before booking confirmation.
What should be true before you continue
Before approving the packing list, reconcile three independent totals: sellable units, physical cartons or pallets, and shipment weight or volume. The quantity by line item should add to the order total; units per carton should reproduce the carton count; and carton dimensions, net weight, and gross weight should be plausible when compared with the packed product. Ask the supplier to explain partial cartons, mixed cartons, accessories, spare parts, and free-of-charge items. Receiving teams and customs brokers need the same final packing facts, not separate versions prepared for different audiences.
Turn the review into a decision record
Do not mark an item complete because it was discussed. Record the current source, revision, date, owner, and remaining uncertainty so another person can understand why the order moved forward.

Ask for the information in one controlled message
Replace the bracketed details, remove any item that does not apply, and ask the supplier or project owner to identify deviations instead of replying with a general confirmation.

Frequently asked questions
Should CBM appear on the packing list?
It is often useful for logistics even when not formally required. Calculate it from final outer dimensions and package quantity.
What is the difference between net and gross weight?
Net weight covers the goods according to the agreed definition; gross weight includes the packed shipment or package. Confirm how pallets and outer packaging are treated.
Can one line cover all cartons?
Only when contents, dimensions, and weights are genuinely consistent. Separate groups when SKUs or packing data differ.
