FOREWORD
The International Convention for the Safety of Life at Sea, 1974 (SOLAS Convention), as
amended, deals with various aspects of maritime safety and contains, in parts A and B of
chapter VI and part A-1 of chapter VII, the mandatory provisions governing the carriage of solid
bulk cargoes and the carriage of dangerous goods in solid form in bulk, respectively.
These provisions are amplified in the International Maritime Solid Bulk Cargoes Code
(IMSBC Code).
Detailed fire protection arrangements for ships carrying solid bulk cargoes are incorporated
into chapter II-2 of the SOLAS Convention by regulations 10 and 19. Attention is drawn to
regulation II-2/19.4 of the SOLAS Convention as amended. This provides for an appropriate
document as evidence of compliance of construction and equipment with the requirements of
regulation II-2/19 to be issued to ships constructed on or after 1 July 2002 and carrying
dangerous goods in solid form in bulk as defined in regulation VII/7 of the Convention, except
class 6.2 and class 7.
For:
-
cargo ships of 500 gross tonnage or over constructed on or after 1 September 1984
but before 1 July 2002; or
cargo ships of less than 500 gross tonnage constructed on or after 1 February 1992
but before 1 July 2002,
-
the requirements of regulation II-2/54 of SOLAS, 1974, as amended by resolutions
MSC.1(XLV), MSC.6(48), MSC.13(57), MSC.22(59), MSC.24(60), MSC.27(61), MSC.31(63)
and MSC.57(67), apply (see SOLAS regulation II-2/1.2).
For cargo ships of less than 500 gross tonnage constructed on or after 1 September 1984 and
before 1 February 1992, it is recommended that Contracting Parties extend such application to
these cargo ships as far as possible.
The problems involved in the carriage of bulk cargoes were recognized by the delegates to
the 1960 International Conference on Safety of Life at Sea, but at that time it was not possible to
frame detailed requirements, except for the carriage of grain. The Conference did recommend,
however, in paragraph 55 of Annex D to the Convention, that an internationally acceptable code
of safe practice for the shipment of bulk cargoes should be drawn up under the sponsorship of the
International Maritime Organization (IMO). This work was undertaken by the Organization’s
Sub-Committee on Containers and Cargoes and several editions of the Code of Safe Practice for
Solid Bulk Cargoes (BC Code) have been published, since the first edition in 1965.
The Sub-Committee was expanded to include dangerous goods and is now called the
Sub-Committee on Dangerous Goods, Solid Cargoes and Containers (DSC Sub-Committee).
The prime hazards associated with the shipment of solid bulk cargoes are those relating to
structural damage due to improper cargo distribution, loss or reduction of stability during
a voyage and chemical reactions of cargoes. Therefore the primary aim of this Code is to
facilitate the safe stowage and shipment of solid bulk cargoes by providing information on the
dangers associated with the shipment of certain types of solid bulk cargoes and instructions

on the procedures to be adopted when the shipment of solid bulk cargoes is contemplated.
The requirements for the transport of grain are covered by the International Code for the Safe
Carriage of Grain in Bulk (International Grain Code, 1991).
The IMSBC Code that was adopted by resolution MSC.268(85) was recommended to
Governments for adoption or for use as the basis for national regulations in pursuance of their
obligations under regulation of the SOLAS Convention, as amended. The Code is mandatory
under the provision of the SOLAS Convention from 1 January 2011. However, some parts of the
Code continue to be recommendatory or informative. It needs to be emphasized that, in the
context of the language of the Code: the words
“shall”, “should”
and
“may”,
when used in the
Code, mean that the relevant provisions are
“mandatory”, “recommendatory”
and
“optional”,
respectively. Observance of the Code harmonizes the practices and procedures to be followed
and the appropriate precautions to be taken in the loading, trimming, carriage and discharge of
solid bulk cargoes when transported by sea, ensuring compliance with the mandatory provisions
of the SOLAS Convention.
The Code has undergone many changes, both in layout and content, in order to keep pace with
the expansion and progress of industry. The Maritime Safety Committee (MSC) is authorized by
the Organization’s
Assembly to adopt amendments to the Code, thus enabling the IMO to
respond promptly to developments in transport.
The MSC, at its eighty-fifth session, agreed that, in order to facilitate the safe transport of solid
bulk cargoes, the provisions of the Code may be applied as from 1 January 2009 on a voluntary
basis, pending their official entry into force on 1 January 2011 without any transitional period.
This is described in resolution MSC.268(85).

General provisions
1.1
Introductory note
1.1.1 It should be noted that other international and national regulations exist and that those
regulations may recognize all or part of the provisions of this Code. In addition, port authorities
and other bodies and organizations should recognize the Code and may use it as a basis for their
storage and handling bye-laws within loading and discharge areas.
1.2
Cargoes listed in this Code
1.2.1 Typical cargoes currently shipped in bulk, together with advice on their properties and
methods of handling, are given in the schedules for individual cargoes. However, these
schedules are not exhaustive and the properties attributed to the cargoes are given only for
guidance. Consequently, before loading, it is essential to obtain current valid information from
the shipper on the physical and chemical properties of the cargoes presented for shipment.
The shipper shall provide appropriate information about the cargo to be shipped
(see section 4.2).
1.2.2 Where a solid bulk cargo is specifically listed in appendix 1 to this Code (individual
schedules for solid bulk cargoes), it shall be transported in accordance with the provisions in its
schedule in addition to the provisions in sections 1 to 10 and 11.1.1 of this Code. The master
shall consider to consult the authorities at the ports of loading and discharge, as necessary,
concerning the requirements which may be in force and applicable for the carriage.
1.3
Cargoes not listed in this Code
1.3.1 If a solid cargo which is not listed in appendix 1 to this Code is proposed for carriage in
bulk, the shipper shall, prior to loading, provide the competent authority of the port of loading
with the characteristics and properties of the cargo in accordance with section 4 of this Code.
Based on the information received, the competent authority will assess the acceptability of the
cargo for safe shipment.
1.3.1.1 When it is assessed that the solid bulk cargo proposed for carriage may present hazards
as those defined by group A or B of this Code as defined in 1.7, advice is to be sought from the
competent authorities of the port of unloading and of the flag State. The three competent
authorities will set the preliminary suitable conditions for the carriage of this cargo.
1.3.1.2 When it is assessed that the solid bulk cargo proposed for carriage presents no specific
hazards for transportation, the carriage of this cargo shall be authorized. The competent
authorities of the port of unloading and of the flag State shall be advised of that authorization.

1.3.2 The competent authority of the port of loading shall provide to the master a certificate
stating the characteristics of the cargo and the required conditions for carriage and handling of
this shipment. The competent authority of the port of loading shall also submit an application to
the Organization, within one year from the issue of the certificate, to incorporate this solid bulk
cargo into appendix 1 of this Code. The format of this application shall be as outlined in
subsection 1.3.3.
