China United Lines
China United Lines (legal entity China United Lines Ltd.) is a regional specialist headquartered in Shanghai, China. Founded in 2018, the line has spent 8 years building out its container service network and today operates a fleet of 36 vessels under the SCAC code CULU. Total operated capacity stands near 90,000 TEU, placing the carrier among the recognised operators on its core trade lanes.
China United Lines is most active on the following corridors: Intra-Asia, Transpacific, Australia. 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 +86 21 3308 8888 or the carrier's web portal at culines.com.
China United Lines corridor coverage
China United Lines concentrates its services on Intra-Asia, Transpacific, Australia. 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 China United Lines container
Tracking a China United 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 culines.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 China United Lines hull. In the last case, the schedule data lives with the operating carrier, not the equipment owner. China United Lines's customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +86 21 3308 8888 during European business hours.
