No. The MLC, 2006, does not prevent employment of seafarers from countries that have not ratified the Convention. However, if seafarers are recruited, to work on board a ship that flies the flag of a country that has ratified the MLC, 2006, through a seafarer recruitment and placement service located in a country that has not ratified the MLC, 2006, then the shipowner using that service must ensure, as far as practicable, that it meets the requirements of Standard A1.4. Must seafarer recruitment and services be certified for compliance with MLC, 2006.
