If you fail to declare food products, you could face up to $10,000 in fines and penalties. If you declare all agricultural products you are bringing with you, you won't be charged any penalties, even if an inspector determines that they can't enter the country.

Yes, it is a legal requirement in almost every country, including the US, UK, and Australia, to declare all food items to customs officers upon arrival, regardless of whether the food is commercially packaged, sealed, or "shelf-stable." While many people assume that a sealed box of crackers or a bar of chocolate is "safe," customs authorities need to verify that the ingredients do not violate local agricultural or biosecurity laws. For example, some packaged "pot noodles" or snacks may contain dried meat or poultry byproducts that could carry diseases like Swine Fever or Avian Flu. If you fail to declare an item—even something as simple as a piece of fruit from the airplane—and it is found during an X-ray or a bag search, you can face immediate fines ranging from $300 to $1,000 and may have your "Global Entry" or "Trusted Traveler" status revoked permanently. The general "Golden Rule" of travel in 2026 is: "When in doubt, declare it." Most of the time, the officer will look at your packaged snack, see it is commercially processed and sealed, and let you go without issue. It is the act of hiding the food that causes the legal trouble, not the food itself.
