The most recent edition of the IMSBC Code has introduced a notable exemption regarding the hazard assessment of iron ore and iron ore fines. Traditionally, these materials were subject to a specific test to determine their potential for localized corrosion, a key factor in their classification.

Now, an alternative test is permitted for this assessment. This change provides shippers with more flexibility and potentially a more efficient way to comply with safety and environmental standards. This exemption is part of a larger, continuous effort to update regulations like MARPOL Annex V and the IMSBC Code to reflect new scientific understanding and technological capabilities, ensuring safety while streamlining the classification process for solid bulk cargoes.
