Summary

It is illegal to break this chapter or its rules, to sell or ship organotin or antifouling products that contain organotin, to make or use organotin to create those products, or to put those products on vessels covered by the chapter. After the Convention takes effect for the United States, it is also illegal to use an antifouling system on a covered vessel in a way that conflicts with the Convention. No vessel may have an organotin antifouling coating on its hull or outer surface unless it has a topcoat that stops organotin from leaching. That topcoat rule does not apply to fixed or floating platforms, FSUs, or FPSOs built before January 1, 2003 that have not been in dry dock on or after that date. Exceptions also exist under an agreement with the Administrator that sets an earlier ban, and for organotin used only for sonar domes or conductivity sensors in oceanographic instruments.
