Published: 13 July 2022

BIMCO provides the full write-up on the final guidance issued by t he International Maritime Organization (IMO) relating to corrosivity test for use in the International Maritime Solid Bulk Cargoes (IMSBC) Code . This test is used for classify ing solid bulk cargoes that are hazardous when transported in bulk (MHB cargoes)

Amendment 06-21 to the IMSBC Code was adopted by the Maritime Safety Committee of the IMO at its 105th meeting held in April 2022. One of the amendments concerned the testing of cargoes for any corrosive hazards in order to see if the cargo is a MHB cargo where an additional test has been incorporated. In connection with this, the IMO also issued final guidance regarding this refined MHB test.
