Frequently Asked Questions about COSCO Group Tracking
What is the difference between COSU and CSLU container codes?
COSU is the original COSCO container prefix, while CSLU comes from the former China Shipping Container Lines (CSCL) which merged with COSCO in 2016. Both are now operated under COSCO Shipping Lines and can be tracked the same way.
How does COSCO's membership in the OCEAN Alliance affect tracking?
The OCEAN Alliance is a vessel-sharing agreement between COSCO, CMA CGM, and Evergreen. Your COSCO container may sail on a vessel operated by any alliance member. Tracking remains the same — use your COSCO container number regardless of the vessel operator.
Can I track COSCO containers destined for Chinese ports?
Yes. ContainerTracking.ai tracks COSCO containers to and from all major Chinese ports including Shanghai, Shenzhen, Ningbo, Qingdao, Tianjin, and Xiamen. Tracking updates are available for both import and export shipments.
How long does a COSCO shipment from China to the US take?
Transit times vary by route. China to US West Coast typically takes 12-18 days, while China to US East Coast (via Panama Canal or Suez Canal) takes 25-35 days. Transshipment stops can add additional days. Check your specific ETA on ContainerTracking.ai for the most accurate estimate.
Why is my COSCO container not returning results?
Ensure you're entering the complete 11-character container number (COSU, CSLU, or CCLU prefix + 7 digits). Tracking by Bill of Lading number isn't supported, but your container number is printed on the Bill of Lading. Tracking data may also take a few hours to appear after the container is gated in.
