Container and refrigerated cargo vessels must comply by January 1, 2023.
Cruise (passenger) vessels are required to adopt shore power by January 1, 2023.
Roll-on roll-off vessels have a compliance deadline of January 1, 2025.
Tanker vessels frequenting the Ports of Los Angeles or Long Beach need to be compliant by January 1, 2025.
All other tanker vessels are given until January 1, 2027, to meet the requirements.

On August 24, 2023, the Ministry of Transport of China issued the "Action Plan for Demonstration and Promotion
of the Use of Shore Power for Container Ships and Cruise Ships on International Routes at Ports (2023-2025)":
