Modul Shipping

SCAC MDLS · Vladivostok, Russia · founded 2002 · Independent / non-aligned

Modul Shipping (legal entity Modul Shipping Lines Ltd.) is a niche operator headquartered in Vladivostok, Russia. Founded in 2002, the line has spent 24 years building out its container service network and today operates a fleet of 5 vessels under the SCAC code MDLS. 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.

Modul Shipping is most active on the following corridors: Russia Far East, Intra-Asia. 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 +7 423 230 9000 or the carrier's web portal at modulship.com.

Modul Shipping 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. Modul Shipping 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 Modul Shipping.

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. Modul Shipping publishes its tracking page under the main modulship.com domain.

Modul Shipping corridor coverage

Modul Shipping concentrates its services on Russia Far East, Intra-Asia. 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 Modul Shipping container

Tracking a Modul Shipping 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. MDLU) 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 Modul Shipping bill of lading. Visit modulship.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 Modul Shipping hull. In the last case, the prefix still resolves to Modul Shipping as equipment owner but the schedule data lives with the operating carrier. Modul Shipping's customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +7 423 230 9000 during European business hours.
