Ship Class B cargo refers to a class of cargo in the dangerous goods classification system of the International Maritime Organization (IMO). The IMO divides dangerous goods into nine different classes, of which Class B goods fall under the category of flammable liquids.

Class B goods mainly refer to flammable liquids, which can burn when exposed to fire or heat. Such cargo may pose a danger to persons, ships and the environment.

For example, gasoline, diesel, kerosene, alcohol, solvents, and certain chemicals are Class B cargoes. Ships transporting Class B cargo need to take corresponding safety measures and regulations to ensure the safe transportation of the cargo and the safety of the ship's navigation.
