What is the 3-1-1 liquids rule? ›

What is the 3-1-1 liquids rule? Each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or100 milliliters. Each passenger is limited to one quart-size bag of liquids, gels and aerosols.

In short, the 3-1-1 rule is: Each liquid you bring through the TSA checkpoint must be in a 3.4-ounce or smaller container ("3"), all containers must be placed inside one clear quart-size plastic bag ("1") and each passenger is only allowed one plastic bag ("1").

Placing these items in the small bag and separating from your carry-on baggage facilitates the screening process. Pack items that are in containers larger than 3.4 ounces or 100 milliliters in checked baggage. Any liquid, aerosol, gel, cream or paste that alarms during screening will require additional screening.

The TSA's liquid limit for carry-ons—known as the 3-1-1 rule—allows travelers to pack liquids, aerosols, gels, creams, and pastes under 3.4 ounces (100 milliliters) in their carry-on bags. Passengers are allowed up to one quart-sized bag per person, or roughly nine 3.4-ounce containers in a single quart-sized bag.

Each passenger is limited to one quart-size bag of liquids, gels and aerosols. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, mouthwash and lotion.

Spray, Gel, Liquid, Cream, Pastes, and Roll-On deodorants need to be in containers no larger than 3.4 ounces and placed in a clear quart-sized baggie.

If you do take liquids in your hand luggage: containers must hold no more than 100ml. containers should be in a single, transparent, resealable plastic bag, which holds no more than a litre and measures around 20cm by 20cm. contents must fit comfortably inside the bag so it can be sealed.

Mascara is considered a liquid; makeup wipes are not a liquid in TSA's rulebook. Cream Blush – Cream blush is a liquid to TSA. Liquid Concealer – Liquid concealer is a liquid and must follow the 311 liquid rule. Lip Balm/Gloss/Lipstick – Lip balm/gloss/lipstick is not considered liquid.

The “3” in the 3-1-1 rule refers to the 3.4 ounce limit. All 3.4-ounce containers must fit into a clear one-quart bag: that's the first “1.” Only one bag is allowed per passenger (that's the last “1” in 3-1-1).

Can I bring a razor in my carry-on? ›

Safety Razors: Because the razor blades are so easy to remove, safety razors are not permitted in your carry-on luggage with the blade. They're fine to pack in your carry-on without the blade. The blades must be stored in your checked luggage. The same applies for straight razors.

Firearms, ammunition, and fireworks are prohibited, as are all knives and safety razors (including pocket knives and Swiss Army knives). Straight razors and replacement blades for straight razors are also not allowed. Most tools also cannot be packed in carry-on luggage, as they have the potential to cause harm.

The size only matters before TSA. Empty water bottles (8 or 12 oz etc) are fine. Anything with liquids in it must be under 3 ounces at screening. It's called the 3–1–1 rule.

What Size Deodorant Can You Take on a Plane? You can bring full-size deodorant if it is stick, solid, powdered, or crystal.

Since a bar of soap is a solid rather than a liquid, TSA puts no restrictions on bringing them through airport security. You can bring a bar soap of any size or as many bars as you wish. And that's true for both your carry-on bag and your checked luggage.

Because soap bars are considered solids, they aren't subject to the same rules as liquid items. In other words, you can pack your favorite soap bar without worrying about a TSA agent throwing it away at the checkpoint.

It's called the 3-1-1 rule because your liquids must be no more than 3.4 ounces (that's the 3), they have to fit into 1-quart bags (there's the 1) and you're only allowed one (that's the final 1) of the bags.

Toothpaste is permitted on aircraft but only in quantities of 3.4 oz (100ml) or less. The same goes for lotion, shampoo, shaving cream, etc. If you are only travelling with carry-on baggage, keep in mind all these rules when bringing your liquids through security checkpoints.
