Flag state

Every merchant ship must be registered in a country — its flag state — and fly that country’s flag. The flag state’s law governs the vessel, and under UNCLOS the flag state carries primary responsibility for enforcing international safety, environmental, and labour standards on board its ships.

Registration does not require any real connection between the owner and the country. Open registries — Panama, Liberia, and the Marshall Islands are the largest, together covering roughly 40% of world tonnage — register ships owned anywhere, and critics call them flags of convenience, arguing they compete on cost and lenient oversight. Traditional maritime nations respond with international registers (such as the Norwegian NIS or Danish DIS) that offer comparable flexibility under a national flag.

Because flag state enforcement is uneven, port state control regimes (the Paris, Tokyo, and other MoUs) inspect foreign ships in port and publish flag performance lists — the practical check on the system. A ship’s flag choice affects taxation, crew nationality and cost, mortgage regimes, and its treatment by charterers and insurers.
