Requirements for Vessels Carrying Bulk Grain Cargo — PURPOSE. This circular calls the attention of Coast Guard field units, shippers and carriers of

bulk grain cargo to the International Maritime Organization's (IMO) Code for the Safe Carriage of Grain in Bulk, referred to as the Grain Code, which entered into force on January 1, 1994. The Grain Code specifies stability, loading requirements, and Documents of Authorization for each vessel that loads grain in bulk.

DIRECTIVES AFFECTED This circular cancels and supersedes NVIC 2-78.

Requirements for Vessels Carrying Bulk Grain Cargo — BACKGROUND. In response to the growing need for broader regulation of the carriage of all

cargoes which may pose a hazard to ships or personnel, the Maritime Safety Committee (MSC) decided to replace the original Chapter VI of the Safety of Life at Sea Convention, 1974 as amended, (SOLAS), which contained detailed regulations on the carriage of grain in bulk, with requirements of a more general nature and to place the detailed provisions on grain in a mandatory code. SOLAS Chapter VI previously titled "Carriage of Grain" is now titled "Carriage of Cargoes." At the 59th session in May 1991, MSS adopted amendments to SOLAS Chapter VI Part C Regulation 9 (resolution MSC.23[59]) to make the International Code for the Safe Carriage of Grain in Bulk mandatory. The Grain Code became effective January 1, 1994.. The Grain Code is available to the public from the IMO as publication 240-E. Information on obtaining this publication can be found in enclosure (1).
