Carriage of calcium hypochlorite in containers - update

IG Circular

Published: 15 January 2018

Circular issued by International Group clubs

Further to our web advice on 31 January 2017 the enclosed guidelines have been prepared jointly by CINS (the Cargo Incident Network System) and the International Group of P&I Clubs.

The practices set out in this document are intended to allow the carriage of calcium hypochlorite under controlled circumstances to ensure that it is properly declared, packaged and carried. The practices are also intended to encourage carriers to have the confidence to accept the commodity for shipment under an acceptable method.

Revised version 3.0 of the IG/CINS Guidelines for the Carriage of Calcium Hypochlorite in Containers

The International Group of P&I Clubs (IG Clubs) and the shipping line members of the Cargo Incident Notification System (CINS) have issued a revised version 3.0 of the Guidelines for the Carriage of Calcium Hypochlorite in Containers. The Guidelines were first published in May 2016, with version 2.0 of the Guidelines issued in January 2017 to take account of the package limit of 100lb drums under US measurement as well as the package limit of 45kg net weight.

As previously stated, the Guidelines can essentially be considered "IMDG Code plus precautions" in that they include selected provisions from the IMDG Code plus additional precautions consistent with the science basis established in 1999 by consulting scientists advising the IG Clubs.

The revised version 3.0 of the Guidelines seek to provide continuity in terms of the referencing of the package limit and provide clarity as to the nature of the Guidelines.

The IG Clubs are an Advisory Member of CINS and many Club Members are also members of CINS. The IG Clubs take the opportunity to encourage other container line members to enquire about CINS membership, the main purpose of which is to highlight and address risks posed by certain cargoes and/or packing failures in order to improve safety in the container liner shipping industry.

All P&I Clubs in the International Group have issued a similar circular.
