Can you take powdered formula through TSA?

Checked Bags: Yes Powder-like substances greater than 12 oz. / 350 mL must be placed in a separate bin for X-ray screening. They may require additional screening and containers may need to be opened. For your convenience, we encourage you to place non-essential powders greater than 12 oz. in checked bags.



Yes, you can absolutely take powdered (and liquid) baby formula through TSA security in 2026, and it is exempt from the 3-1-1 liquids rule. Unlike standard liquids, formula, breast milk, and baby food are considered "medically necessary liquids" and can be brought in "reasonable quantities" that exceed 3.4 ounces (100ml). When you reach the security checkpoint, you must declare the formula to the TSA officer and remove it from your carry-on bag for separate screening. While powdered formula is generally easier to screen, TSA may still perform additional testing on it, such as using an "Explosive Trace Detection" swab on the exterior of the container or asking you to open it for a visual inspection. To speed up the process, travelers are advised to keep the formula in its original packaging and to allow for an extra 10–15 minutes for the specialized screening. In 2026, some airports now utilize "Bottle Screeners" that can analyze liquid formula without opening the bottle, but powdered formula remains the most "security-friendly" and convenient way to transport infant nutrition across international borders.
