Practical guides for a Hawaiʻi port call.
Clear, honest guides to help captains, managers, and operators prepare for a call in the Hawaiian Islands — what to gather, what to expect, and where an agent helps. Information to prepare with, not a substitute for the authorities who make the decisions.
Prepared vessels have smoother calls.
Most friction in a Hawaiʻi port call comes from missing information, not missing effort. These guides lay out what to gather and what to expect so your arrival, clearance, fuel, and crew logistics move without avoidable delay. They are written to be genuinely useful — no filler, no promises we cannot keep.
Each guide is general information to help you prepare. Requirements change and depend on the vessel, flag, cargo, and the authorities involved, so always confirm current requirements with HYANS and the relevant authorities before arrival. HYANS coordinates and supports; clearance, inspection, and entry decisions rest with the authorities.

Which guide should I read first?
This guide is general information to help you prepare, not legal, immigration, customs, tax, or navigation advice. Requirements change and vary by vessel, flag, and cargo. Clearance, inspection, and entry decisions rest with the responsible authorities — including U.S. Customs and Border Protection (CBP), USDA/APHIS, the U.S. Coast Guard, and harbor authorities. HYANS coordinates and supports; the authorities decide. Confirm current requirements before arrival.
