Amendment of IMO Guidelines for Development of Inventory of Hazardous Materials - IHMs 10.08.2025 22:45
The IMO has adopted Res. MEPC.405(83) – “Amendments to the 2023 Guidelines for the development of the Inventory of Hazardous Materials”.
These amendments clarify the threshold values of Cybutryne in Anti-fouling system samples taken either from wet paint containers or taken directly from the hull.
This Marine Environment Protection Committee (MEPC) resolution amended the Appendix 6 (Form of Material Declaration) by replacing the threshold value of 1000 mg/kg of the Anti-fouling systems containing Cybutryne with a value of 200 mg/kg.
The amendments to the "2023 Guidelines for the Development of the Inventory of Hazardous Materials" adopted on 7 July 2023, clarifying the threshold values of cybutryne in anti-fouling system coating samples, either taken from wet paint containers or taken directly from hull.
The Member Governments were invited to apply the amendments as soon as possible, and no later than 26 June 2025:
Ships already holding an IHM Manual Part I:
• Persons responsible for the IHM maintenance are requested to confirm that the Material Declarations (MD) prepared on or after 26 June 2025 (i.e. for new coatings) are based on the new format as per MEPC.405(83).
New Ships:
• Shipyards and suppliers are requested to prepare the MD using the new format as per MEPC.405(83).
