On April 17, 2018, an important notice was received from MSC Shipping Company: the ocean bill of lading prefix issued by MSC was switched from MSCU to MEDU. During the current transition period, both types of bill of lading prefixes can be accepted by the MSC, but pay attention to the format. If transmitted in the form of MSCU + MEDUABC123456, it will be rejected.

The modification of the MSC prefix of the bill of lading will have a certain impact on the maritime tracking, in addition to affecting the format of the bill of lading itself.
