Broadly, ships flying flags of Party States, when on international voyages. Each chapter (I to XII) defines the ships to which that chapter applies. Application may depend on type of ship (e.g. chapter X - High Speed Craft), or date of build (e.g. chapter II-1 - Construction - subdivision and stability, machinery and electrical installations), area of operation (e.g. chapter V - Safety of navigation), tonnage (e.g. chapter IV - Radio communications) or cargoes (e.g. chapter VI - Carriage of cargoes and oil fuels). Each chapter may also exempt certain ships from the chapter's requirements.

A rule in major IMO conventions that, when inspecting a ship flying the flag of a State which is not a party to the Convention, Port State Control Officers must ensure that the treatment of such a ship and its crew is not more favourable than that of a ship flying the flag of a State party to that Convention. For example, many States have not yet ratified or acceded to MARPOL Annex VI, but ships flying their flags will still be required to meet the requirements of Annex VI to pass port State control inspections.
