COC证书是美国海岸警卫队（USCG）签发给运载液体散装危险货物（如原油或其他石油产品、化学品、液化天然气或压缩天然气）的非美国旗油轮的证书。COC证书不是必需的国际性证书，而是非美国旗油轮在美国通航水域作业所需的特别性证书。目的是确保防止不合格的油船在美国海域运营并威胁其海岸线和领海。
在美国港口进行装卸或运输任何液体散装危险货物时，船上必须携带有效的COC证书。

Certificates Of Compliance For Tank Vessels In The United States
A COC is a certificate issued by the United States Coast Guard (USCG) to non-US flag tank vessels carrying liquid bulk hazardous cargoes, such as crude oil or other petroleum products, chemicals, liquefied gas, or compressed gas. The COC is not a required international certificate; it is a unique certificate needed for non-US flag tankers to operate in the navigable waters of the US. The goal is to ensure that no substandard tank vessel is operating in the US and threatening its coastline and territorial waters.
A valid COC must be aboard the vessel when loading, discharging, or carrying any liquid bulk hazardous cargoes into a US port.
