Prevention of Pest Contamination of Containers: Joint Industry Guidelines for Cleaning of Containers

These guidelines have been prepared by COA, IICL, WSC and ICHCA International. they are complementary to the guidance given in the IMO/ILO/UNECE Code of Practice for Packing Cargo Transport Units (“CTU Code”) regarding prevention of pest contamination of containers.

COA Guidelines for Carriage of Cargo in Non-Operating Reefers

In order to minimise empty repositioning costs, container operators frequently use reefer containers in a “non-operating” mode to carry approved dry cargo – either on a return leg or to re-position the equipment without operating the refrigeration machinery.

Transporting “non-operating reefer” (NOR) cargo enables the carriage of additional cargo, where reefers need to be positioned for their next cargo move, but are competing for slot space with revenue-earning dry cargo.

Because of the differences between General Purpose and Refrigerated containers (both the design and the materials), the approval of NOR cargo – and the packing requirements – must be taken into account.

A new document entitled “Guidelines for the Carriage of Cargoes in Non-Operating Reefer Containers” has been published this month by the Container Owners Association – in conjunction with the CINS (the Cargo Incident Notification System) organisation  ( The Guidelines have been sponsored by the TT Club.
