The Maritime Safety Committee, at its 107th session (31 May to 9 June 2023), following the adoption of resolution MSC.500(105) on Amendments to the International Maritime Solid Bulk Cargoes (IMSBC) Code and considering the proposal by the Sub-Committee on Carriage of Cargoes and Containers, at its eighth session, with regard to implementation of 1.3.3 of the IMSBC Code, approved a revision of the Guidelines for the submission of information and completion of the format for the properties of cargoes not listed in the IMSBC Code and their conditions of carriage (MSC.1/Circ.1453/Rev.1), as set out in the annex.
Member Governments are invited to bring the annexed Guidelines to the attention of all concerned, taking into account the voluntary application date of 1 January 2023 for amendment 06-21 of the IMSBC Code, pending its envisaged mandatory entry-into-force date of 1 December 2023.
When a cargo which is not listed in the International Maritime Solid Bulk Cargoes (IMSBC) Code is intended to be carried in bulk, the competent authority of the port of loading should provide to the master a certificate stating the characteristics of the cargo and the required conditions for carriage and handling of that shipment.
The competent authority of the port of loading should also submit an application to the Organization to incorporate this solid bulk cargo into appendix 1 of the IMSBC Code.
The format of this application should be as outlined in 1.3.3 of the IMSBC Code.
These Guidelines provide guidance on the type and structure of information which is required in the application.
The application should be supported as a minimum by relevant data such as may be contained in Material Safety Data Sheet (MSDS), Safety Data Sheet (SDS) or other relevant documentation.
Applicants should therefore complete and submit the questionnaire in the appendix.
Where applications indicate use of equipment or systems, references to relevant internationally agreed standards for such equipment or systems should be indicated.
