The provisions of this section address the security of bulk cargoes in
transport by sea. It should be borne in mind that some substances shipped as bulk cargo
may, through their intrinsic nature, or when shipped in combination with other
substances, be used as constituents for, or enhance the effect of, weapons used in the
commission of unlawful acts. (It should also be borne in mind that ships used to carry
bulk cargoes may also be used as a means to transport unauthorized weapons, incendiary
devices or explosives, irrespective of the nature of the cargo carried.) National
competent authorities may apply additional security provisions, which should be
considered when offering or transporting bulk cargoes. The provisions of this chapter
remain recommendatory except 11.1.1.
