International Association of Classification Societies (IACS) is a technical organization consisting of twelve marine classification societies (out of around 50), headquartered in London.
It is estimated that these 12 societies, collectively class about 94% of all commercial tonnage involved in international trade worldwide.
IACS provides a forum within which the member societies can discuss, research and adopt technical criteria that enhance maritime safety. With its extensive knowledge of the industry and fleet, IACS provides a massive contribution to international shipping and regulations.
It holds a consultative status with the IMO and regularly participates in the capacity of an observer as well as an adviser to the IMO and the member states. IACS also enables cooperation with the Port State Control (PSC) to ensure high quality in the maritime field.
