Sloman Neptun

SCAC SLNE · Bremen, Germany · founded 1873 · Independent / non-aligned

Sloman Neptun (legal entity Sloman Neptun Schiffahrts-AG) is a regional specialist headquartered in Bremen, Germany. Founded in 1873, the line has spent 153 years building out its container service network and today operates a fleet of 22 vessels under the SCAC code SLNE. Total operated capacity stands near 15,000 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.

Sloman Neptun is most active on the following corridors: Mediterranean, Atlantic, Caribbean. 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 +49 421 6203 0 or the carrier's web portal at sloman-neptun.com.

Sloman Neptun 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. Sloman Neptun 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 Sloman Neptun.

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. Sloman Neptun publishes its tracking page under the main sloman-neptun.com domain.

Sloman Neptun corridor coverage

Sloman Neptun concentrates its services on Mediterranean, Atlantic, Caribbean. 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 Sloman Neptun container

Tracking a Sloman Neptun 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. SLNU) 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 Sloman Neptun bill of lading. Visit sloman-neptun.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 Sloman Neptun hull. In the last case, the prefix still resolves to Sloman Neptun as equipment owner but the schedule data lives with the operating carrier. Sloman Neptun's customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +49 421 6203 0 during European business hours.
