The TSA liquid rule says that you can get a one-quart size bag with liquids, creams, aerosols, pastes, and gels in the carry bag and across the airport security check. However, you have limited containers on travel size and also should have less than 100 ml (3.4 ounces) per item.

The products that are packaged larger than 3.4 ounces or 100 ml will need to go in the checked luggage. In addition to large liquids, any of the liquids having over 100 ml or 3.4 oz isn’t and not kept in a tamper-proof bag, should be packed with checked luggage.

3-1-1- Rule of TSA

Each of the liquids needs to have 3.4 ounces or lesser containers. All of the containers have to be placed in clear plastic bag, and each of the passengers is allowed to carry one plastic bag. 

What Are The Exceptions For TSA Liquid Rule?

There are mainly two exceptions to the TSA limit, and this includes:

● Medicines.

● Child or infant nourishment.

What about Medicines Over 100 ml?

You don’t need to stress about this at all. TSA allows medical gels, aerosols, liquids of over 100 ml. This will also be including medical accessories like a pump, syringes, freezer bags, etc. The items don’t have to be wrapped or kept in a plastic bag. But keep in mind that you need to declare such items to your TSA officers at the checkpoint before you go for inspection.

You must know that some of the states have laws where you need to have a prescription label on the medications. Therefore check for the rules of the state before you travel. 

And while we are discussing medicines, were you aware that you can take syringes as well?

So when you are carrying an unused syringe, it has to be filled with the medicine and needs to be separately stored in hard-surface containers. 

What about Juice, Breast/Formula Milk?

Breast milk, formula, or juices for toddlers or infants are allowed through airport security checkpoints. These are the liquids that can be more than 100 ml or 3.4 ounces and can be kept on the carry-on baggage.

Like some of the medicines, make sure you inform TSA officers of what you have been taking with you. Also, take them out of the bag so that they can be screened separately from everything else. 

Freezer bags, ice packs, gel packs, and such accessories needed to cool, breast milk and formula can easily be taken in the carry-bag.

The pre-check TSA program does allow travelers for going ahead expedited the screening line for over 200 US airports and more than 80 airlines participating. Once you have been approved into this program, you won’t have to remove the 3-1-1 liquid from the bags.

What Are the Things TSA Consider to be Liquid?

As per the TSA guidelines, any of the free-flowing, viscous substances will be considered liquid. This shall include paste, juice, gels, and creams.

Does Makeup Count As Liquid?

There is a chance that you didn’t give this a thought, but most cosmetics are liquids. Often time’s quantity of specific liquid makeup stays less than 3.4 oz. But make sure that you aren’t filling up the quart bag with the products that you don’t need.

As per TSA, makeup in powder or solid form can be taken in a carry-on bag, and there is no size or quantity limitation for it. However, when you have packed it in the carry-on bag, makeup that’s liquid, cream, gel, or paste form has to be stored in containers equal to or less than 3.4 ounces. It’s recommended that you take travel-size liquids that fit well in 1 zip-top quart-sized bag.

When we speak of makeup, the liquid cosmetics include:

● Nail paints

● Perfumes

● Foundations

● Mascara, etc.

Can You Take Toothpaste Onboard?

While you can easily take toothpaste in hand luggage, any toothpaste counts in the gels and liquid limit. Additionally, the toothpaste has to be lower than 3.4 oz or 100 ml. Look for toothpaste packages that say “Travel size” or “TSA approved”.

What about Deodorant?

You can bring specific kinds of deodorants in the carry-on. 

When it’s in liquid form, i.e., gel, spray, roll-on, it has to be under the restriction of 3.4 oz or 100 ml. This rule also applies to your perfumes that are also liquids. Therefore if you wish to carry your deodorant in the carry-on luggage, it must abide by the 100 ml requirements. 

The solid deodorants are permitted in both your checked and carry-on bag and don’t follow the 100ml rule. This means that if you bring stick deodorant, you can bring one in any size. 

Some Packaging Tips for the Liquid Products

Here we have for you some tips that can come in handy while you are packing liquids as per TSA liquid rules:

  1. Make use of refillable bottles. This way, they can be of perfect size and filled again as needed.
  2. Put the essentials in your carry-on bag.
  3. Try going for perfume stick and solid makeup. It won’t count as liquid, and you are safe here from the hassle.
  4. Double seal the containers and bottles. For making sure nothing opens mid-flight and stays secure.
