Revised NetZero eligibility requirements for vessels making their first Panama Canal transit take effect on 1 November. Advisory A-40-2026 was issued on 30 October.
A preliminary admeasurement determination is required before the slot competition. Inspections can take place outside Panama, subject to technical documentation, arrangements and applicable charges.
Submitting a request does not establish eligibility. The preliminary process also does not replace final verification or any additional inspection required before transit.
