Thai International Sea Lines
Thai International Sea Lines (legal entity Thai International Sea Lines Co., Ltd.) is a niche operator headquartered in Bangkok, Thailand. Founded in 2002, the line has spent 24 years building out its container service network and today operates a fleet of 6 vessels under the SCAC code THSL. Total operated capacity stands near 5,000 TEU, placing the carrier among the recognised operators on its core trade lanes.
Thai International Sea Lines is most active on the following corridors: Intra-Asia, Mekong. The line operates on a standalone basis and does not share vessel slots with other ocean carriers under a formal global alliance. Direct customer contact is available via +66 2 670 0470 or the carrier's web portal at thaiintsealines.com.
Thai International Sea Lines corridor coverage
Thai International Sea Lines concentrates its services on Intra-Asia, Mekong. Customers on these lanes typically see weekly or twice-weekly sailings depending on season and trade balance. For a current sailing schedule, contact the carrier directly or consult its weekly schedule publication.
How to track a Thai International Sea Lines container
Tracking a Thai International Sea Lines container starts with confirming the prefix. Look at the container's left-hand corner casting plate or the painted code on the door — the four-letter ISO 6346 owner code is followed by six numeric digits and a single check digit. Blue Water Facts no longer publishes a per-carrier owner-prefix list (see /accuracy/ for why); confirm the operator via the carrier's own tracking portal or your bill of lading. Visit thaiintsealines.com, navigate to the carrier's tracking or "track and trace" portal, and paste the full container number. The portal will return current vessel position, the next scheduled port call, the estimated time of arrival (ETA) and the most recent equipment events such as gate-in, loaded, discharged and gate-out.
If the carrier portal does not return a result, the most likely causes are: the container has not yet been gate-in at the origin terminal, the bill of lading number is in a different format (check whether the system expects an MBL versus an HBL), or the box is moving on a partner alliance vessel rather than a Thai International Sea Lines hull. In the last case, the schedule data lives with the operating carrier, not the equipment owner. Thai International Sea Lines's customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +66 2 670 0470 during European business hours.
