New substance added for Antifoulings!

The maritime industry knows the AntiFoulingSystem-Convention (AFS-Convention) very well. As of 2023 it bans new application of Cybrutyl-containing AntiFouling-Coatings. If present it has to be either removed or covered, latest by 2025.

The Hong Kong Convention will enter into force on June 26th, 2025. Until recently the related IHM-Guidelines mentioned organotin only as a biocide in AntiFouling-Coatings, but not Cybrutyl. As a consequence of amendments to AFS-Convention, Cybrutyl has been added to the new IHM-Guidelines of IMO (MEPC-Res. 379(80), see download section). Ships´ IHMs have to cover this additional substance once HCK will enter into force.

Thinking ahead means that already today Cybrutyl should be integrated in the scope of IHM and IHM-Maintenance. We have decided to amend the related Material Declarations by adding Cybrutyl to the list of banned substances (Table A / Annex I of EUSRR).

Suppliers have required data at hand and requesting to share this already today avoids costly re-sampling and hazzles when shipowners have to proof absence of Cybrutyl in their AntiFouling-Coatings in near future.

 What about your IHM-Maintenance? Is Cybrutyl included in your forms and scope?
