In 2026, applesauce is classified by the TSA and global aviation authorities as a liquid or gel, meaning it is subject to the strict 3-1-1 rule for carry-on luggage. To bring it through security, the container must be 3.4 ounces (100ml) or less and fit inside a single quart-sized clear bag. However, there is a significant exception: if you are traveling with an infant or toddler, applesauce (including puree pouches) is considered medically necessary liquid and can be brought in "reasonable quantities" exceeding 3.4 ounces. You must declare these items to security officers for separate screening. If you are not traveling with a child and want to bring a larger jar, it must be packed in your checked baggage. TSA officers have the final discretion on whether an item is allowed through the checkpoint, so keeping it in its original, clearly labeled packaging is advised to avoid delays during the X-ray process.
