About China United Lines (CULines)
China United Lines, branded CULines and identified by the SCAC code CULU, was founded in 2005 and is headquartered in Shanghai, with a significant operating base in Singapore. It began as an intra-Asia and cross-strait operator, running services between mainland China, Taiwan, Hong Kong, Japan, South Korea, and Southeast Asia, and it built out coastal and Yangtze River trades alongside charter business.
The line drew wide attention during the 2021 to 2022 freight boom, when it pushed into deep-sea Asia to Europe and Asia to Mediterranean lanes and briefly climbed inside the world's top 25 container carriers. That expansion proved hard to sustain once rates normalized. CULines withdrew from its long-haul Asia to Europe service and exited a vessel-sharing arrangement with Antong (QASC), and its fleet capacity contracted sharply from its pandemic peak.
Since then the carrier has refocused on regional trades where it competes on flexibility and price, adding direct routes linking China with India, Southeast Asia, the Middle East, the Red Sea, and the Eastern Mediterranean. In 2025 it set up CUL Turkey as an Eastern Mediterranean regional hub anchoring a trunk-and-feeder network, and it launched its own digital booking platform. CULines operates independently, outside the three main global carrier alliances.
