Going through customs on a cruise in 2026 has become increasingly digitized. Upon returning to your "home port" (e.g., Miami or Southampton), you typically undergo a "face-to-face" or biometric check. For many U.S. ports, "Facial Recognition" technology now replaces the physical passport scan; you simply look into a camera, and the system verifies your identity and entry eligibility in seconds. For "Customs" specifically, you are required to declare any goods exceeding your duty-free allowance. On most modern cruises, this is done via a digital declaration form in the cruise line's app before you even disembark. If you have nothing to declare (the "Green Channel"), you simply walk through the terminal after the biometric check. If you have agricultural items, excess alcohol, or high-value purchases, you must enter the "Red Channel" to speak with a Customs and Border Protection (CBP) officer and pay any applicable duties.
