The Document of Compliance (DOC) is a mandatory certificate that must be carried on board cargo ships as stipulated by the International Safety Management (ISM) Code. In China, the DOC certificate is issued by maritime authorities to shipping companies in accordance with ISM regulations.

The DOC certificate serves as a crucial legal document between vessels and cargo owners. It demonstrates that the ship management company has undergone audits for environmental protection, safety, and quality standards under international conventions, proving its capability to independently manage maritime operations. This signifies that documentation, instructions, procedures, and operational standards in areas such as ship construction, safety equipment, navigation management, maintenance plans, and ship environmental management are developed in compliance with relevant international standards. For shipbrokers and cargo owners, the DOC certificate can also serve as an evaluation criterion when selecting carriers for transport contracts. By providing the DOC certificate in contracts, ship management companies certify their relevant qualifications, offering assurance to both contractual parties.

CnOpenData presents the Directory of DOC-Holding Shipping Companies, encompassing domestic and international shipping companies holding DOC certificates. The directory includes fields such as DOC number, company name, applicable ship types, and validity dates, thereby facilitating related research.
