TSA Rules for Flying With Powders

We all know how important it is to stay hydrated, fueled, and energized when traveling. But nothing slows down your journey faster than having your bag pulled aside for extra screening—especially when it’s just electrolytes, protein powder, or seasonings inside.

Since 2018, TSA has enforced stricter rules on powders in carry-on bags. If you’re traveling with electrolyte powders, protein supplements, or other food powders, knowing these TSA-approved packing tips will help you breeze through security without unnecessary delays.

Can You Take Powders on a Plane? TSA Rules Explained

Powders under 12 oz.(350 ml) - Allowed in Carry-On

Stick packs and small containers under 12 oz. are allowed in carry-on bags with no quantity restrictions.
TSA may still request secondary screening at their discretion.

Powders Over 12 oz. (350 ml) - Allowed in Carry-On, But Must Be Removed for Screening

TSA states, “Containers of powdered drink mix over 12 oz. should be removed from your carry-on bag and placed in a bin for X-ray screening. You may also consider packing non-essential powders greater than 12 oz. in checked bags.”

If your container is over 12 oz., take it out of your bag and put it in a separate bin for screening.
The TSA sometimes looks at the container size, not the amount of powder inside. So even if a 15-oz. jar is half full, it may be treated as a full 15-oz. container and require screening.
Officers may open the container to inspect or test the powder.
Exception: Baby formula and medically prescribed powders are exempt from secondary screening.

Will TSA Allow Re-Lyte and Real Salt in Carry-On Bags?

While our products are generally allowed through security checkpoints, we have occasionally heard from customers that the TSA has denied Re-Lyte Jars and Real Salt Pouches after screening.

The TSA does not share details about the specifics of its powder screening process, so we can’t say for sure why this happens. However, because Re-Lyte and Real Salt contain high levels of minerals and sodium, they may resemble specific chemical markers used in security screenings.

TSA officers can refuse any item if they can not resolve a security concern, even if that item is typically allowed.

This is rare, but to avoid frustration, the safest way to travel with Re-Lyte Jars or Real Salt pouches over 12 oz. is to pack them in checked luggage. If you choose to bring them in your carry-on, be prepared for additional screening and the possibility that TSA may not allow your item through.

International Travel: Can I Take My Electrolyte Powder Through Customs?

If you’re traveling internationally with electrolyte powders, protein supplements, or any food powder, check customs regulations for the country you’re traveling to. Some countries have strict rules on powdered supplements, food powders, and salt products, which could affect whether your items are allowed.

To avoid surprises at customs, research local regulations ahead of time and consider bringing only sealed individual servings or small containers for the best chance of smooth travel. Packing powders in their original, sealed packaging can also help reduce scrutiny during inspections.

Final Tips for Traveling With Powders

TSA’s powder rules might seem complicated, but following simple steps will make travel easier. Stick Packs, Pocket Shakers, and small containers are the best choices for carry-on, as they’re TSA-friendly and hassle-free. If you’re bringing a container over 12 oz., be prepared to remove it for screening.

Whenever possible, keep powders sealed in their original packaging or clearly labeled to avoid confusion. If you’re traveling internationally, check customs regulations ahead of time to prevent any surprises.

With a little TSA-friendly packing and preparation, you can fly with food powders stress-free and stay well-hydrated wherever your journey takes you. Safe travels!
