Solid food items (not liquids or gels) can be transported in either your carry-on or checked baggage. TSA officers may instruct travelers to separate items from carry-on bags such as foods, powders, and any materials that can clutter bags and obstruct clear images on the X-ray machine.

In most cases, you can take commercially packaged biscuits through international customs, as they are considered "processed" and "low-risk" food items. Most countries, including the U.S. (CBP), the UK, and Australia, allow travelers to bring in baked goods that do not contain fresh fruit or meat fillings. The baking process typically kills off pests and diseases that customs officials are trying to keep out. However, you must always declare them on your customs form if asked about food. While a sealed pack of digestive biscuits or shortbread is usually fine, homemade biscuits or those containing "restricted" ingredients like fresh cream or certain seeds might be confiscated. Australia and New Zealand are particularly strict; even though biscuits are generally allowed, failing to declare them can lead to heavy on-the-spot fines. In 2026, it is always a "best practice" to keep the biscuits in their original store packaging so that agents can easily read the ingredient list. If you are unsure, the rule of thumb for international travel is: "If it's processed, cooked, and shelf-stable, it's usually allowed, but always declare it."
