ASEAN Seas Lines

SCAC ASEN · Singapore · founded 2015 · Independent / non-aligned

ASEAN Seas Lines (legal entity ASEAN Seas Pte. Ltd.) is a niche operator headquartered in Singapore. Founded in 2015, the line has spent 11 years building out its container service network and today operates a fleet of 4 vessels under the SCAC code ASEN. Total operated capacity stands near 3,500 TEU, placing the carrier among the recognised operators on its core trade lanes. The company holds intermodal equipment under 3 registered ISO 6346 owner prefixes, which appear on every box it owns or long-term leases.

ASEAN Seas Lines is most active on the following corridors: South-East Asia, ASEAN. 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 +65 6334 7700 or the carrier's web portal at aseanseas.com.

ASEAN Seas Lines container prefixes

Every intermodal container carries an ISO 6346 owner code — three letters identifying the owner, plus a single category letter (almost always U for freight containers). These four-letter prefixes are the fastest way to identify which carrier controls a given box. ASEAN Seas Lines has the following registered prefixes recorded in the BIC database. If a container in your possession begins with any of these codes, the box is owned by or leased on long term to ASEAN Seas Lines.

To track a container under one of these prefixes, contact the carrier directly using the bill-of-lading number or container number. Most ocean carriers expose a public tracking endpoint on their website that accepts either format. ASEAN Seas Lines publishes its tracking page under the main aseanseas.com domain.

ASEAN Seas Lines corridor coverage

ASEAN Seas Lines concentrates its services on South-East Asia, ASEAN. 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 ASEAN Seas Lines container

Tracking a ASEAN Seas 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 (e.g. ASNU) is followed by six numeric digits and a single check digit. If the prefix matches one in the list above, the box is on a ASEAN Seas Lines bill of lading. Visit aseanseas.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 ASEAN Seas Lines hull. In the last case, the prefix still resolves to ASEAN Seas Lines as equipment owner but the schedule data lives with the operating carrier. ASEAN Seas Lines's customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +65 6334 7700 during European business hours.
