Shipping is probably one of the most regulated industries in the world. For engaging in maritime trade ships require various certificates issued on behalf of their flag State confirming their compliance with various international conventions related to safety and environment protection that the vessel is required to comply with. As provided in these conventions, most governments have delegated such certification activities to classification societies such as ISClass, in view of their technical expertise and international presence. ISClass is duly authorized by the following countries to perform surveys, audits and plan appraisals as per various international conventions, codes and national regulations and to issue certificates. 航运业可能是世界上监管最严格的行业之一。从事海上贸易的船舶需要代表其船旗国签发各种证书，确认其符合船舶必须遵守的与安全和环境保护有关的各项国际公约。根据这些公约的规定，鉴于艾氏船级社等船级社的技术专长和在国际上的存在，大多数政府已将此类认证活动委托给这些船级社。艾氏船级社获得下列国家的正式授权，根据各种国际公约、规范和国家法规进行检验、审计和计划评估，并颁发证书。
