The Panama Canal has implemented updates to the slot allocation criteria in the Neopanamax locks with new changes to the transit reservation system. These changes, which take effect immediately, have reinstated the allocation criteria prior to July 2026.
New Slot Allocation Criteria
During reservation periods 1A and 2, available slots will be offered through a special allocation process, where priority is given in order to container ships, liquefied natural gas (LNG) carriers, liquefied petroleum gas (LPG) carriers, and roll-on/roll-off (RoRo) ships. In each of the ship categories, the Transit TEU Allowance (TTA) capacity is considered the main criterion for determining priority.

Update on NetZero Program Requirements
The Panama Canal has also updated the requirements for ships entering the NetZero program. This program, aimed at supporting investment in low-carbon and energy-efficient ships, allows new vessels to participate. According to the new requirements, ships must undergo an initial fleet inspection by the Panama Canal measurement unit. These inspections can also be conducted outside of Panama.
From November 1, 2026, ship owners, operators, or authorized representatives can request an initial inspection before the ships enter the canal waters. This measure allows the Panama Canal to obtain the necessary information to calculate fees, determine the tonnage of ships under the Panama Canal Universal Measurement System (PC/UMS), identify engine type, and confirm other requirements for participation in the NetZero program in advance.
Applicants must provide the required technical documentation, pay all related fees and charges, and make necessary arrangements at the port where the ship is located. The initial inspection does not replace final approval or any additional inspections that may be required before transit.
These measures generally strengthen the Panama Canal's commitment to encouraging the adoption of low-carbon and energy-efficient ships while maintaining clear and predictable criteria for transit capacity allocation.
