Does customs search checked luggage?

Does customs inspect all luggage? The short answer is “no”, but of course the reality is not black and white. in general, customs do not have the resources to inspect all the luggages. At the same time, there are situations when the inspections are more thorough.



Yes, customs authorities have the legal right to search any checked luggage entering a country in 2026. This search can happen in two ways: "behind the scenes" or in your presence. Most luggage is screened via high-speed CT scanners that use AI to detect explosives, narcotics, or bulk currency without ever opening the bag. If the scanner identifies a suspicious "organic mass" or prohibited item, customs officers will perform a physical search. In many cases, this happens in a secure area before the bag reaches the carousel; if they open it, they will usually place a "Notice of Inspection" inside. Alternatively, after you collect your bag, a customs officer in the arrival hall may stop you and ask to search your luggage manually based on a "random selection" or behavioral cues. In 2026, the use of TSA-approved locks is essential, as it allows officers to open your bag with a master key rather than cutting the lock, ensuring your property remains secure for the rest of your journey.
