Documentation is the backbone of any international trade operation. Among these documents, the packing list acts as the technical inventory of the shipment: it details what is being shipped, how it is packed, how many packages there are, and their weights and dimensions.
The packing list is the practical reference for customs, carriers, insurers and warehouse teams, and facilitates physical inspection, verification against the commercial invoice and correct handling of cargo throughout the logistics chain.
Although not always a legal requirement in itself, it is often required or highly recommended because it reduces discrepancies, speeds up dispatches and minimizes error costs.
In combination with the commercial invoice and transport documents, the packing list provides the physical traceability that international operations require.
What is a packing list in international logistics?
The packing list, is a logistics document that details the exact contents of a shipment. It is used to technically and objectively describe the goods, specifying their quantity, weight, volume, type of packaging and distribution in packages or pallets.
Unlike the commercial invoice, the packing list does not reflect economic values, but physical and descriptive information about the cargo. In this sense, it acts as a logistics inventory that accompanies the shipment and serves as a reference for all parties involved: exporters, importers, carriers, customs brokers and insurers.
Its use is common in practically all international shipments, by sea, air and land, as it facilitates document management and avoids discrepancies in customs inspections.
Although it is not a mandatory legal requirement in some countries, it is often required by customs authorities in support of the commercial invoice and transport documents.
In short, the packing list is a document that:
📑 Complements commercial and transport documentation.
📦 Allows physical verification of goods during inspections.
🚚 Facilitates handling, loading and unloading at different stages of the logistics chain.
🛡️ Serves as backup evidence in case of claims or incidents with the cargo.
Main functions of the packing list
The packing list plays an essential role in international trade because it connects the commercial, logistical and customs information of each shipment. It is not a financial document, but its correct preparation allows the entire documentary and operational flow to be more agile and secure.
Among its most important functions are the following:
📦 Facilitate customs clearance: authorities can check that the declared goods match what was shipped, both in quantity and in description and packaging. This reduces the risk of additional inspections, detentions or penalties.
Verify the contents of the shipment against the commercial invoice: while the invoice reflects economic values, the packing list provides the physical details of the shipment. Together they confirm the consistency between what was sold and what was transported.
🚚 Optimize handling and transport: by including dimensions, weights and number of packages, carriers can better plan cargo space as well as distribution in warehouses and containers.
🛡️ To support claims or insurance: in case of loss, damage or discrepancies, the packing list acts as a reference document to verify what was actually shipped and in what condition.
🔄 Improve traceability: by assigning references or numbering to each package, it is easier to track the goods at different points in the logistics chain.
In short, the packing list not only serves to comply with a documentary requirement, but is also a practical tool for control and efficiency in international operations.
Mandatory elements of a packing list
A packing list must contain accurate and complete information to be valid for international operations. Although the format may vary according to the company or country of destination, there are certain data that are considered essential for it to fulfill its function:
Exporter and importer data: full name, address, country and, in some cases, tax identification number.
🧾 Associated commercial invoice number: direct reference to link the packing list to the economic transaction.
📦 Detailed description of the goods: product name, internal reference or code, materials and relevant characteristics.
🔢 Number of packages: how many boxes, pallets or containers make up the shipment.
⚖️ Gross weight and net weight: gross weight includes packaging; net weight corresponds to the product only.
Dimensions of each package: length, width and height, essential for volume calculation and transport planning.
🛠️ Type of packaging used: e.g. cartons, sacks, pallets, drums, containers, etc.
🔖 Reference number or package identification: each unit must be individually traceable in case of inspection or incident.
Place and date of shipment: specify the origin of the cargo and the date on which the packing list is issued.

How to make a packing list step by step
A correct packing list is essential to avoid delays, incidents or additional costs in international operations. Although each company can adapt the format to its needs, the process must follow a series of structured steps:
Collect shipment information
Review the commercial invoice and the original purchase order.
Identify all products included in the shipment.
Confirm quantities, references and final recipient.
Describe the goods in detail
Specify name, internal reference or product code.
Include relevant characteristics (material, model, serial number if applicable).
Avoid generic descriptions that may generate doubts in customs.
Define the unit load
Group products in bundles (boxes, pallets, drums, etc.).
Number each package for easy identification and traceability.
Associate the contents of each package with the corresponding reference.
Indicate weights and dimensions
Record the net and gross weight of each package.
Measure length, width and height to calculate volume (CBM – cubic meters in shipping).
This information allows the planning of stowage and space in containers or vehicles.
Link to commercial invoice and other documents
Indicate the invoice number to which the shipment corresponds.
Ensure consistency with the bill of lading (B/L, AWB or CMR).
Check that there are no discrepancies between economic values and physical quantities.
Review and validate information
Verify that the data is complete and correct.
Confirm that the total weights match those declared in the shipment.
Check spelling and formatting, as errors may result in retentions.
Generate copies and keep the document
Issue a physical copy to accompany the shipment.
Save digital version in the company’s management systems.
Provide copy to customs broker, carrier and customer where applicable.
Packing list and commercial invoice: how they complement each other
In an international trade operation, the packing list and the commercial invoice are different documents, but they are used together because each provides complementary information.
🧾 The commercial invoice reflects the economic value of the transaction: it identifies the buyer and seller, establishes the price of the goods, the terms of sale (Incoterms) and serves as the basis for calculating duties and taxes.
The packing list, on the other hand, describes the physical composition of the goods: number of packages, weights, dimensions, type of packaging and details of what each cargo unit contains.
By complementing each other, they play key roles in international logistics:
🔗 Documentary consistency: the commercial invoice establishes the economic value, while the packing list guarantees that the declared quantities and references match what was transported.
🚛 More agile customs: the combination of both documents allows the authorities to verify both the commercial aspect (price, origin, Incoterm) and the physical aspect (content, volume, packaging).
🛡️ Legal and operational security: in case of dispute, claim or damage, having an invoice and packing list is essential to prove what has been shipped and its valuation.
📊 Better logistics control: together they provide a complete picture: what was sold, for how much, how it was packed and how it is transported.
In conclusion, the packing list and the commercial invoice form an indispensable binomial: while one justifies the commercial operation, the other ensures traceability traceability and the correct logistical management of the goods.
Benefits of a well-prepared packing list
A properly prepared packing list is not only a documentary requirement, but a tool that provides efficiency and safety throughout the logistics chain. Its advantages are especially noticeable in international operations, where any error can result in delays and additional costs.
The main benefits include:
🚀 S treamlines customs procedures: by accurately detailing the cargo, it reduces the likelihood of additional inspections and facilitates the release of the goods at the border.
📦 Optimizes logistics planning: with clear information on weights, measures and number of packages, carriers and operators can better organize space in warehouses, containers or trucks.
Avoids documentary discrepancies: by complementing the commercial invoice, it ensures consistency between the economic value of the operation and the physical detail of the transported goods.
🛡️ Reinforces security in case of incidents: in situations of loss, damage or theft, the packing list serves as a reference document for claims against the insurer or shipping company.
Improved traceability: package numbering and individualized cargo identification allow for more accurate tracking throughout the international journey.
Generates confidence in partners and customers: a clear and professional packing list conveys transparency and reliability in the management of shipments.
In short, drawing up a quality packing list not only complies with a documentary standard, but also constitutes a best practice in international logistics, capable of reducing costs, saving time and avoiding conflicts.
Consequences of a bad packing list
An incomplete, erroneous or inaccurate packing list can have a considerable negative impact on a company’s international operations. Since it is a document that serves as a reference for customs, transport and insurance, any failure in its preparation can result in additional costs and loss of efficiency.
Among the most frequent consequences are:
⛔ Customs holds: lack of information or discrepancies with the commercial invoice often generate additional inspections, delaying the release of the goods.
💸 Increased logistics costs: delays at the border can result in storage costs, container demurrage charges and containers (demurrage) or additional transportation costs.
⚖️ Sanctions and penalties: in certain countries, errors in documentation may result in fines or administrative blocking of cargo.
Confusion in the handling of goods: if packages are not correctly identified, the risk of errors in loading, unloading or distribution in warehouses increases.
🛡️ Insurance and claims problems: in the event of a claim, the absence of a detailed packing list can make it difficult or even impossible to obtain adequate compensation from the insurer.
🤝 Loss of trust with customers and partners: unclear documentation conveys a lack of professionalism, which can affect the company’s image in international operations.
In short, a poorly prepared packing list not only slows down the operation, but can also generate cost overruns and reputational risks that directly affect the company’s competitiveness in international markets.
