The International Code for the Safe Carriage of Grain in Bulk (International Grain Code)


The International Code for the Safe Carriage of Grain in Bulk (International Grain Code), adopted by resolution MSC.23 (59), has been mandatory under SOLAS chapter VI since 1 January 1994. The term "grain" covers wheat, maize (corn), oats, rye, barley, rice, pulses, seeds and processed forms thereof, whose behaviour is similar to that of grain in its natural state. The International Grain Code applies to ships regardless of size, including those of less than 500 gross tonnage, engaged in the carriage of grain in bulk and to which part C of SOLAS chapter VI applies. The purpose of the Code is to provide an international standard for the safe carriage of grain in bulk.
The International Grain Code requires a document of authorization to be issued for every ship loaded in accordance with the Code. The document of authorization serves as evidence that the ship is capable of complying with the requirements of the Code and it must be accompanied or incorporated into the grain loading manual which contains information that enables the master to meet the stability requirements of the Code. A copy of the document of compliance together with the grain loading stability data and associated plans shall be carried on board in order that the master, if so required, shall produce them for the inspection of the Contracting Government of the country of the port of loading.
The contents of the International Grain Code are divided as follows:
Part A - Specific Requirements
Section 1 - Application

Section 12 - Divisions loaded on both sides
