This class notation is mandatory for vessels carrying such cargo.

Ships built to carry cargoes not requiring full compliance with the Tanker for Chemicals requirements are assigned this notation with C indicating the type of cargo for which the ship is classified.

Approval is carried out by the responsible approval centre. The site survey is carried out at the building yard and its suppliers. A periodical survey is carried out on board vessel.

The notation is assigned following survey reports verifying compliance with the DNV rules.

Process
