C1.2.g. Is a medical certificate issued in the seafarer’s home country valid for work on a ship flying the flag of a different country?

Under the MLC, 2006 a medical certificate is valid if it is issued by a duly qualified medical practitioner. However, the flag State of the ship concerned is responsible for deciding whether the signatory of the medical certificate is indeed duly qualified. Some flag States will recognize medical certificates issued elsewhere, but others may require an examination by a practitioner based in the flag State [see C1.2.e.].
