Some Terms

1.4 Application and implementation of this Code
1.4.1 The provisions contained in the IMSBC Code apply to all ships to which the SOLAS Convention, as amended, applies and that are carrying solid bulk cargoes as defined in regulation 1-1 of part A of chapter VI of the Convention.

1.4.2 Although this Code is legally treated as a mandatory instrument under the SOLAS Convention, the following provisions of this Code remain recommendatory or informative:
– Section 11 Security provisions (except subsection 11.1.1);
– Section 12 Stowage factor conversion tables;
– Section 13 References to related information and recommendations;
– Appendices other than appendix 1, Individual schedules of solid bulk cargoes; and
– the texts in the sections for “Description”, “Characteristics”, “Hazard” and “Emergency procedures” of individual schedules of solid bulk cargoes in appendix 1.

1.4.3 In certain parts of this Code, a particular action is prescribed, but the responsibility for carrying out the action has not been specifically assigned to any particular person.
Such responsibility may vary according to the laws and customs of different countries and the international conventions into which these countries have entered.
For the purpose of this Code, it is not necessary to make this assignment, but only to identify the action itself.
It remains the prerogative of each Government to assign this responsibility.

Group A, B or C:
Group A: consists of cargoes which may liquefy if shipped at a moisture content in excess of their transportable moisture limit.
Group B: Solid bulk cargoes possessing chemical hazards (With UN classification or MHB) or as per definition:
It consists of cargoes which possess a chemical hazard which could give rise to a dangerous situation on a ship.
Group C: consists of cargoes which are neither liable to liquefy (Group (A) nor to possess chemical hazards (Group B).

Note: some cargoes are both Group A and B

Angle of Repose (AoR): 
the maximum slope angle of non-cohesive (i.e. free flowing) granular material.

Materials Hazardous only in Bulk (MHB)
Means materials which may posses chemical hazards when carried in bulk other than materials classified as DG in the IMDG Code.

Transportable Moisture Limit (TML):
of a cargo which may liquefy means the maximum moisture content of the cargo which is considered safe in ships not complying with the special provisions of 7.3.2.
It is determined by the test procedures, approved by a C.A., such as those specified in para 1 of appendix 2.

Bulk Cargo Shipping Name (BCSN):
Similar to the Proper Shipping Name in the IMDG Code. It identifies a Dry Bulk Cargo during transport by sea. (Note: IMDG Code N.O.S. names should NOT be used unless specifically approved by the Competent Authorities).

Resolution MSC.354(92)
This was adopted 21 June 2013 and is generally called “IMSBC Code edition 2” or “IMSBC Code 2013 edition”.

When it is assessed the a solid bulk cargo proposed for carriage may present hazards as those defined in Group A or B (See above), advice is to be sought, by the Competent Authority of the port of loading, of the C.A. of the port of discharge and the flagstate.(See
