Thailand flag: FAQ

Is the Thailand flag safe for seafarers?
The Thailand flag has a mixed PSC record — some inspection regimes class it favourably, others less so. It has ratified MLC 2006, which is the principal worker-protection convention. Operator and class are usually a stronger signal than flag alone.
Has Thailand ratified the Maritime Labour Convention (MLC 2006)?
Yes — Thailand has ratified MLC 2006 (ratified 2016). Seafarers serving on Thailand-flagged vessels are entitled to make MLC complaints through the flag administration, port state, or seafarer welfare organisations such as the ITF.
How do I file a complaint against a Thailand-flagged vessel or operator?
Complaints can be lodged with the Marine Department, Thailand via their official complaint procedure. Under MLC 2006, complaints may also be lodged with the port-state authority of any MLC-ratified port. The ITF and seafarer welfare organisations (Mission to Seafarers, Stella Maris, Sailors' Society) can advocate on your behalf. Keep contract, wage records, and seaman's book ready.
What port-state-control rating does Thailand have?
Paris MoU rating: not-listed. Tokyo MoU rating: white. PSC ratings classify flags by inspection and detention history. White / low-risk flags face fewer PSC inspections; black / high-risk flags face more frequent inspection and a higher detention rate.
Is Thailand on the ITF Flag of Convenience (FoC) list?
No — Thailand is not currently on the ITF Flag of Convenience list. Seafarers retain general ITF-channel access for advocacy and abandonment response regardless of FoC status.
