The IMSBC Code amended by IMO Resolution MSC.539(107) is referred to as "IMSBC Code 7th Amendment" in this Technical Information.
The current IMSBC Code 6th Amendment is valid until 31 December 2024. Therefore, ClassNK Technical Information No.TEC-1283 dated 21 December 2022 will be revoked on 31 December 2024.

1. Application of the IMSBC Code 7th Amendment
The IMSBC Code 7th Amendment to revise individual schedules of cargoes was adopted by the IMO Maritime Safety Committee 107th session (MSC107) held in June 2023. The Amendment will enter into force on 1 January 2025 and will be mandatory for all ships loading solid bulk cargoes on or after 1 January 2025.

2. Cargoes newly added or revised
The IMSBC Code 7th Amendment contains individual schedules of cargoes newly added or revised, which refer to Attachment 1. "Table 1 - Cargoes newly added and requirements on construction/equipment (IMSBC Code 7th Amendment)". When carrying these cargoes, rewriting of the IMSBC Code fitness certificate is required.

3. Request of issuing the IMSBC Code fitness certificate
In case requesting issuance of the fitness certificate for the IMSBC Code 7th Amendment, please refer to Attachment 2. "Guidance for the application of IMSBC Code 7th Amendment fitness certificate".

4. Application of the IMSBC Code 7th Amendment on a voluntary basis
The IMSBC Code 7th Amendment may be applied on a voluntary basis from 1 January 2024 as a transition period. Therefore, in principle, ClassNK would issue IMSBC Code fitness certificates in accordance with the IMSBC Code 7th Amendment based on the following scheme.
