What Is the Liquid Limit at TSA?

Transportation Security Administration (TSA) regulations, commonly referred to as the 3-1-1 rule or the TSA liquid restriction, limit the amount of liquid that travelers are permitted to bring in their carry-on bags:
- Each jar contains 100 ml (3.4 ounces).
- Every container needs to fit within a clear zip-top bag.
- One bag per traveler
- This holds for aerosols, pastes, creams, gels, and liquids. Checked luggage is required for anything larger.
What Counts as a Liquid Under the TSA Liquid Limit?
The TSA applies the 3-1-1 rule to more than just water or juice. Many everyday travel products fall under this category, even if they don’t seem like liquids at first glance.
TSA Liquid - Pastes, Gels, and Creams Also Matter
Despite their apparent solidity, toothpaste, lotion, sunscreen, foundation, and lip gloss are all classified as "liquids" under TSA regulations.
Example from Real Life:
You want to take your favorite 150ml sunscreen in your backpack for your flight to Bali. TSA will require you to discard anything in your carry-on that weighs more than 3.4 ounces (100 milliliters). Alternatively, choose a travel-sized version that fits in your quart-sized plastic bag or stow it in your checked suitcase.
TSA Liquid - Foods and Semi-Liquids Are Included
Foods that are classified as liquids include peanut butter, soup, yogurt, and jam. The 3.4 ounce guideline applies to everything that can be spread or poured.
Example from Real Life:
You wish to bring home some homemade chili sauce that you purchased at a nearby market. Even if it is sealed, TSA will flag it if it is in your carry-on. You must store it in your checked luggage, making sure to pack it tightly to prevent leakage.

It's okay to bring full-sized toiletries, drinks, or large liquid containers on your trip; just make sure to put them in your checked luggage rather than your carry-on. Only carry-on luggage are subject to the TSA's liquid restrictions, so you are free to bring more as long as you follow the packing and safety regulations.

Total Quantity | Subject to airline baggage weight policies (e.g., 23 kg/50 lbs.) |
Packaging | Must be securely closed and ideally wrapped to prevent leaks |
Container Type | Rigid bottles preferred; no fragile or unsealed items |
Prohibited Liquids | Flammable items (e.g., fuel, lighter fluid) not permitted |
TSA-Approved Liquids for Checked Luggage
Item Type | Allowed in Checked Bag | Notes |
|---|---|---|
Full-size shampoo | ✅ Yes | It should be under 500 ml to avoid breakage risks |
Bottled water | ✅ Yes | Not recommended due to potential bursting |
Wine or alcohol | ✅ Yes (with limits) | Must be under 70% ABV; up to 5 liters permitted |
Aerosol spray (e.g., hairspray) | ✅ Yes | Must have protective cap |
