Convention for Safe Containers (CSC) Training

International Convention for Safe Containers, 1972

The Institute of International Container Lessors (IICL) would like to introduce our first on-line educational training course. This initial effort will focus on The International Maritime Organizations (IMO) Convention for Safe Containers (CSC).



With the introduction of the modern day cargo container in the 1960's it soon became apparent that there was a need for standardization and a control for industry wide safety. The International Standards Organization (ISO) focused on the container itself and the dimensional and structural requirements for standardization. In 1972 the IMO working in conjunction with ISO standards initiated CSC.

In 1972, a conference jointly convened by the United Nations and IMO was held to consider a draft convention prepared by IMO. The Convention for Safe Containers adopted by the conference had two goals: maintain a high level of safety of human life in transport and handling and to facilitate the international transport of containers by providing uniform international safety regulations. This has provided a foundation for global consistency and relevance in container safety procedures.

In 1983 the original re-examination interval under Periodic Examination Scheme (PES) was extended to 30 months and the Approved Continuous Examination Program (ACEP) was adopted as an alternative to provide container owners with a choice of schemes to utilize to meet their container examination requirements.

The CSC Convention has continued to evolve over time with the most recent changes having gone into effect on 1 July 2014.

The recent changes include:

  • New definitions at the beginning of annexes I and II, along with consequential amendments to ensure uniform usage of terminology throughout CSC 1972.
  • Amendments to align all physical dimensions and units to the SI system.
  • The introduction of a transitional period for marking containers with restricted stacking capacity, as required under the relevant standard.
  • The inclusion in annex III of the list of deficiencies that do not require an immediate out-of-service decision by the control officer but do require additional safety measures to enable safe ongoing transport.

The IICL is therefore offering its educational training class that highlights key components of the CSC Convention as well as the policies and procedures necessary for owners, operators and shippers to follow as set forth by the Convention.

Included in this training class are the key articles of the convention as well as testing requirements set forth by ISO. The class will allow the student to understand the basic requirements of CSC and also allow them the ability to ask the instructor questions. In addition and for a more complete understanding the students are encouraged to purchase the IMO's 2014 CSC publication that contains the most recent amendments and updates to the convention and circulars. The publications can be purchased at the time of the course registration, at the following links or through both the Examination/Courses and Publications/Tools stores on the IICL's website.

To purchase CSC publications:


The IICL CSC course is presented as informational and instructive as to the terms set forth by the International Maritime Organization (IMO) in their 1972 Convention regarding container safety. The IMO does not certify individuals in the requirements or procedures as described in the Convention for newly manufactured or modified containers.
