  5. With this Convention, flag states will verify ship's antifouling system and issue "International anti-fouling system certificate" based on Safety Data Sheet (SDS) or similar document submitted by the ship-owner or the ship operator.

The puropose of this Rule is to provide IMO Convention compliance information and related information to ship owners, ship operators, government authorities in charge and other related bodies by examining paints manufactured/distributed by JPMA Regular members, Supporting members or non-membership companies.

In Japan, manufacturing of TBTO is prohibited since it was defined as "Class 1 specified chemical substances" by Law concerning the Examination and Regulation of Manufacture etc. of Chemical Substances (Hereinafter KASHINHO) in 1989. TPT compounds (7 substances) and TBT compounds (13 substances) were defined as "Class 2 specified chemical substances"in 1990, requiring report for manufacturing / importing of these substances, and they do not exist in Japan since 1996. Therefore, antifouling paints for ships manufactured in Japan may recognize as not containing organotin compound.
