Packing and intermodal transport

CTU Code: packing cargo transport units

The IMO/ILO/UNECE CTU Code is a global code of practice for handling and packing cargo transport units. It helps coordinate safe packing across sea and land transport.

Who is the CTU Code for?

The 2014 Code addresses the intermodal transport chain, including those who pack and secure cargo and those who receive and unpack units. IMO describes guidance on loading, securing, dangerous goods and training on its CTU Code overview.

It is useful when responsibilities are shared between a consignor, warehouse, packing contractor and carrier. The ILO publication page also identifies people who train packers among its intended users.

Is the CTU Code mandatory?

IMO describes it as a non-mandatory global code of practice. This status should not be confused with the legal requirements that apply to a particular consignment, transport mode or operation. For packaged dangerous goods at sea, the IMDG framework must also be considered.

The CTU Code can support a packing procedure or review, but citing it does not on its own demonstrate compliance with all applicable obligations. Sources: IMO CTU Code overview and IMO IMDG framework.

Where to find the official text

The ILO publication page provides a PDF download and links to other language versions. IMO also links to the Code and related materials from its overview page.

IMO distinguishes the accompanying informative material from the Code itself: it supplies practical background but is not part of the Code. Check which document a procedure, training handout or contractual reference actually cites.

Preparing a packing review in Spain

Start by mapping the operation: who supplies the goods, who selects the unit, who packs it, which carriers take over and who unpacks it. Record the transport stages and the information exchanged at each handover.

Useful material for an initial DGSA enquiry includes the cargo description, transport unit type, planned route, current packing procedure and available photographs or diagrams. For dangerous goods, also identify the available classification and transport documentation. Avoid sending unrelated personal or commercially sensitive information.

DGSA can discuss the scope of a technical review in English or Spanish. See multimodal advice, staff training and our IMDG Code 2024 guide.
