The Document of Compliance (DOC) certificate is a mandatory document that cargo-carrying vessels must possess on board in accordance with the International Safety Management (ISM) Code. In China, the DOC certificate is issued by the Maritime Safety Administration (MSA) to shipping companies under the provisions of the ISM Code.

  The DOC certificate serves as a crucial legal document between vessels and cargo owners. It certifies that the ship management company has passed audits for environmental protection, safety, and quality standards under international conventions, demonstrating its capability to independently manage maritime operations. This indicates that documentation, instructions, procedures, and operational standards related to ship construction, safety equipment, navigation management, maintenance plans, and environmental management comply with relevant international standards. For ship brokers and cargo owners, the DOC certificate can also serve as an evaluation criterion when selecting carriers for transportation contracts. By providing the DOC certificate in contracts, ship management companies demonstrate their qualifications, offering assurance to both parties involved.
