CSNU Container Tracking — COSCO Shipping Lines-Owned Prefix
Track on elines.coscoshipping.com — official COSCO Shipping Lines tracker
COSCO Shipping Lines is China’s state carrier and the fourth-largest fleet worldwide, formed when COSCO and China Shipping merged in 2016.
Its box pool mixes group registrations — including one code formally held by the group’s own leasing arm Florens yet painted on fleet containers — so the family is smaller than the fleet suggests.
