On April 17, the Office of the United States Trade Representative took action on the "Section 301 Investigation of China’s Targeting of the Maritime, Logistics, and Shipbuilding Sectors for Dominance to eliminate China’s acts, policies, and practices targeting the maritime, logistics, and shipbuilding sectors for dominance."

For the first 180 days, applicable fees will be set at zero.

In the first phase actions, after 180 days:

• Fees on vessel owners and operators of China based on net tonnage per U.S. voyage, increasing incrementally over the following years - the fee would start at $50/NT in 180 days and increases by $30/NT per year over the next three years;
• Fees on operators of Chinese-built ships based on net tonnage or containers, increasing incrementally over the following years - the fee would start at $18/NT or $120 per container in 180 days, and would increase by $5/NT per year, or the same proportional yearly amount per container (e.g., in year 2, to $154 per container), over the next three years; and
• To incentivize U.S.-built car carrier vessels, fees on foreign-built car carrier vessels based on their capacity - the fee would start at $150 per Car Equivalent Unit (CEU) capacity of the entering non-U.S. built vessel in 180 days. 

The second phase actions will not begin for 3 years:

• To incentivize U.S.-built liquified natural gas (LNG) vessels, limited restrictions on transporting LNG via foreign vessels. These restrictions will increase incrementally over 22 years.

Furthermore,

• Fees on Chinese vessel operators and owners and Chinese-built ships are assessed per U.S. voyage, not per port call. These fees are imposed on a given ship no more than five times per year.
• Fees are not “stacked,” meaning only one fee will be assessed per U.S. voyage.
• Upon proof of order of a U.S.-built vessel, fees or restrictions on an equivalent non-U.S.-built vessel are suspended for up to three years.
• Fees on Chinese-built ships effectively do not cover Great Lakes or Caribbean shipping, shipping to and from U.S. territories, or bulk commodity exports on ships that arrive in the United States empty.
