1. Fees now apply per voyage, not per port call.
This makes it less likely for shippers to cut stops at key export ports (like Oakland).
2. Fees are based on vessel size.
Smaller ships, especially those running short-haul routes, will see lower fees.
3.Exemptions include:
- U.S. domestic-only routes
- Ports in the Caribbean, U.S. territories, and Great Lakes
- Ships arriving empty to pick up exports
Rollout begins October 14, 2025, with a gradual increase over 3 years.
