The Hawaiian Islands are one of the most isolated archipelagos in the world and the southernmost state in the United States. Due to this geographic isolation Hawaii must protect its natural beauty from other ecosystems. That means do not bring pets, produce or animals that can introduce pests and non-endemic species to Hawaii’s fragile environment, as this could be destructive.

Note that the Department of Agriculture enforces strict rules regarding the exportation of uninspected plants and animal into Hawaii. You are required to fill out a declaration form describing the items you are bringing into Hawaii upon arrival. Your incoming airline carrier will provide you with this declaration form on the plane prior to arrival. Conversely when you leave Hawaii your luggage must pass a pre-flight AG inspection for uninspected fruits and plants.

If you want to take plants, fruit and fresh flowers home… you are welcome to take inspected items purchased at the airport or local vendors as long at they have an AG inspection sticker on them. Or better yet have those inspected items shipped home for you.
