Founded in 1956, China Classification Society (CCS) is headquartered in Beijing and is a full member of the International Association of Classification Societies (IACS).
CCS provides classification services to ships, offshore installations and related industrial products by furnishing world-leading technical rules and standards. CCS also provides statutory surveys, impartial and integral classification, verification, certification and accreditation and other services in accordance with international conventions, regulations and the related rules and regulations of the authorizing flag states or regions. As authorized by the administrations of the flag states or regions, CCS carries out statutory survey and other services as authorized by the administrations.
