TSA Liquid Rules 2026: What You Can Carry and How Much You Can Bring

Planning to fly this year? Before you zip up your carry-on, you need to know exactly what TSA will and won’t let through the checkpoint. The rules around liquids remain the single biggest source of confiscated items and security delays at U.S. airports.

This updated guide covers the TSA liquid limit, the 3-1-1 rule, all applicable exceptions as of 2026, and the new security changes quietly reshaping the airport experience.

The TSA Liquid Limit in 2026: The 3-1-1 Rule Still Stands

Despite years of speculation about whether the rule would be relaxed, the TSA liquid limit has not changed in 2026. The federal standard remains the familiar 3-1-1 rule, and it applies at every TSA checkpoint across the United States.

TSA’s 3-1-1 rule allows liquids, gels, and aerosols in carry-on bags, provided they are in containers of 3.4 ounces (100ml) or less, all fitting inside one, quart-sized, clear, plastic, zip-top bag (1 bag per passenger). Liquids exceeding this size must be packed in checked luggage.

TSA Liquid Rules

Despite rumors of its retirement, the 3-1-1 Liquids Rule remains the federal standard for all U.S. airports in 2026. While the technology used to inspect your bags has improved, the legal limit on what you can bring remains unchanged.

What Is The 3-1-1 Rule?

TSA cares about the bottle size, not how much is left. If you have a 6oz bottle of shampoo that’s nearly empty, they’ll still toss it.

3.4 Ounces (100ml): All liquids, gels, aerosols, creams, and pastes must be contained in a container that holds 3.4 ounces or less.

1 Bag Per Passenger: Each traveler is limited to one liquid bag in their carry-on.

1 Quart-Sized Bag: All your 3.4oz containers must fit comfortably inside a single, clear, quart-sized, resealable plastic bag.

There are no limits on the number of other (non-liquid) bags you can include, provided they fit in your carry-on.

You are typically permitted to carry a clear, resealable bag for liquids, gels, and aerosols, as long as it is quart-sized or smaller, in your carry-on luggage. The bag must close completely, and all items inside must be 3.4 ounces (100 milliliters) or less.

If you are flying through a modern terminal with CT scanners and you have TSA PreCheck, the “3-1-1 rule” becomes almost invisible. You just put your bag on the belt and walk through.

But if you’re flying out of a smaller regional airport, keep that quart-sized bag at the very top of your carry-on; you’ll likely still need to pull it out for the old-school X-ray machines.

How Many Ounces Can You Carry on An Airplane?

The simple answer is 3.4 ounces. If it’s “spreadable, sprayable, or squeezable” (like peanut butter, hairspray, or mascara), the TSA considers it a liquid. When in doubt, either move it to your checked bag or swap it for a solid version (like a shampoo bar).

You are permitted to carry a quart-sized bag containing liquids, aerosols, gels, creams, and pastes in your carry-on luggage and through the security checkpoint. Each item must be in a travel-sized container of 3.4 ounces (100 milliliters) or smaller.

To streamline the screening process, it is advisable to place these items in a small bag and keep them separate from your carry-on baggage. Items in containers larger than 3.4 ounces or 100 milliliters should be packed in checked luggage.

TSA Liquid Rules 2026: What Counts as a Liquid?

This is where most travelers get caught out. The TSA definition of “liquid” is broader than you might expect. The following are all treated as liquids under the TSA liquid rules:

• Gels (hair gel, aloe vera, lip gloss)
• Aerosols (hairspray, dry shampoo, spray sunscreen, deodorant)
• Creams and lotions (moisturizer, foundation, BB cream)
• Pastes (toothpaste, face masks)
• Spreadable foods — peanut butter, hummus, jam, dips, and yogurt all fall under the liquid rule. In 2026, these remained among the top confiscated items at U.S. checkpoints.

A useful rule of thumb: if you can pour it, pump it, squeeze it, or spread it, TSA treats it as a liquid.

Any liquid, aerosol, gel, cream, or paste that triggers an alarm during screening will require further inspection.

What Is NOT Considered a Liquid?

Solid versions of toiletries are TSA’s best-kept secret for frequent travelers. Shampoo bars, solid conditioner bars, solid sunscreen sticks, bar soap, and solid deodorant sticks do not count as liquids and can go straight into your carry-on without any size restriction.

Where Do You Put Your Items: Carry-Ons vs Checked Baggage?

Item	Carry-On Allowed?	Limit (Carry-On)	Checked Bag Allowed?	Notes
Shampoo	✅ Yes	≤100 ml (3.4 oz)	✅ Yes	Full-size goes in checked
Conditioner	✅ Yes	≤100 ml	✅ Yes	Same as shampoo
Toothpaste	✅ Yes	≤100 ml	✅ Yes	Considered a paste
Deodorant (spray/roll-on)	✅ Yes	≤100 ml	✅ Yes	Aerosols count as liquids
Deodorant (solid stick)	✅ Yes	No limit	✅ Yes	Not considered liquid
Perfume	✅ Yes	≤100 ml	✅ Yes	Fragile—seal properly
Lotion / Moisturizer	✅ Yes	≤100 ml	✅ Yes	Counts as liquid

Makeup (liquid)	✅ Yes	≤100 ml	✅ Yes	Foundation, mascara
Makeup (powder/solid)	✅ Yes	No limit	✅ Yes	Not restricted
Shaving Cream (foam)	✅ Yes	≤100 ml	✅ Yes	Aerosol rules apply

TSA Liquid Rules: 4 Official Exceptions Every Traveler Should Know

The traditional 3-1-1 rule (liquids limited to 3.4 oz in a quart-size bag) generally still applies, but 11 specific items are now exempt and can be carried in any size through security checkpoints. Some items may require a declaration for inspection.

There are three main categories where TSA allows you to bypass the 3-1-1 rule. However, these items must be declared to the officer at the start of the screening process.

Medical Liquids and Gels

Prescription liquids, IV bags, and even large bottles of contact lens solution are permitted. In 2026, TSA officers use “Bottle Liquid Scanners” (BLS) to verify these without opening the containers.

Tip: Keep your prescription label on the bottle to expedite the process.

Baby and Toddler Nourishment

If you are traveling with an infant or toddler, you can bring:

• Breast milk (including “thawed” or “slushy” states).
• Formula and distilled water for mixing.
• Baby food pouches and jars.
• 2026 Rule: You do not need to have the child with you to transport breast milk.

Frozen Liquids

If a liquid is frozen solid at the moment it passes through the X-ray, it does not count as a liquid. However, if there is even a small amount of “slush” or melted water at the bottom of the container, it will be treated as a liquid and must be 3.4oz or less.

Important notes

• These exemptions apply only at airports equipped with CT scanners, not universally.
• Everyday liquids like shampoo, sunscreen, and drinks still must follow the 3-1-1 rule.
• Prohibited items remain banned regardless of size.

Bottom line: TSA security is becoming more flexible for medically necessary and special-case liquids, but most travelers should still pack as if the 3-1-1 rule applies.

 International Duty-Free Liquids

Liquids purchased at international duty-free shops may exceed the standard limit, provided they are sealed in a tamper-evident bag and accompanied by proof of purchase showing they were bought after the security checkpoint. This is a narrow exception — do not count on it for domestic purchases.

New TSA Changes in 2026: What’s Different This Year

While the liquid rules themselves haven’t changed, the airport security experience has shifted significantly in 2025–2026. Here’s what’s new and what it means for your next trip.

CT Scanners Are Replacing Traditional X-Ray Machines

The biggest practical change to the carry-on experience: by early 2026, over 90% of major U.S. hubs — including ATL, LAX, JFK, and ORD — have replaced traditional X-ray machines with 3D CT scanners. These machines create a three-dimensional image of your bag’s contents that officers can rotate 360 degrees.

The practical benefit for travelers: at airports equipped with CT scanners, you no longer need to remove your liquids bag or your laptop from your carry-on before sending it through. TSA officers can see through the bag clearly enough without you unpacking it.

Important caveat: this does not change the 3.4 oz rule. You still need to pack compliant liquids. CT scanners simply allow you to leave the quart bag inside your carry-on instead of pulling it out at the bin. Always check signage at your specific checkpoint — instructions vary by lane and airport.

REAL ID Is Now Enforced — and Non-Compliance Has a Cost

REAL ID enforcement began in May 2025, and as of February 1, 2026, travelers without a REAL ID-compliant driver’s license or acceptable alternative (such as a passport) face a $45 non-refundable ConfirmID fee to pass through security. This fee covers a 10-day travel period and the verification process can take up to 30 minutes — so plan accordingly.

A REAL ID-compliant license has a star symbol in the top corner. If yours doesn’t have it, visit your state DMV or use a valid passport instead.

Shoes Stay On — For Now

In July 2025, TSA ended its nearly 20-year mandatory shoe removal policy. As of 2026, most passengers can keep their shoes on at standard security checkpoints. TSA officers may still ask you to remove your footwear if an alarm sounds or if you are selected for additional screening.

However, the policy is facing political pressure in April 2026. A classified DHS Inspector General report found that some TSA advanced imaging scanners cannot effectively screen shoes, prompting Senator Tammy Duckworth to formally demand that the shoes-on policy be reversed. For now, the policy remains in place, but travelers should follow officer’s instructions at each checkpoint regardless.

New Items Banned from Checked Luggage

TSA has also prohibited three new items from checked baggage in 2026:

• Cordless curling and straightening irons that use gas cartridges
• Butane-filled curling and straightening irons
• Spare gas cartridges for any of these devices

These items must now go in your carry-on or be left at home. Lithium batteries also remain under heightened scrutiny: spare battery packs must travel in carry-on bags, and some airlines now require they stay on your person rather than in the overhead bin. Check your airline’s specific policy before flying.

TSA Liquid Limit for Checked Baggage vs Carry-On

The TSA restricts carry-on liquids under the 3-1-1 rule, permitting travelers to bring liquids, aerosols, gels, creams, and pastes in containers of 3.4 ounces (100 milliliters) or less.

This is where most travelers lose their snacks. Even if it feels “thick,” if it’s spreadable, it follows the 3.4oz rule.

• Nut Butters: Peanut butter, almond butter, and Nutella.
• Dips & Spreads: Hummus, cream cheese, guacamole, and salsa.
• Sweeteners: Honey, maple syrup, and agave.
• Dairy: Yogurt, pudding, and soft cheeses (like Brie or Camembert).
• The “Sandwich Loophole”: Interestingly, if that peanut butter is already spread on a sandwich, it’s considered a solid “food item” and can be any size. If it’s in a jar, it’s a liquid.

Each container must adhere to the 3.4-ounce (100 milliliters) limit to comply with TSA regulations. Items such as liquids, gels, aerosols, creams, and pastes must fit comfortably within the quart-sized bag.

Category	Carry-On Luggage	Check-in Baggage
Liquids	3-1-1 Rule: 3.4oz (100ml) or less per container; all must fit in 1 quart-sized clear bag.	Unlimited for most items. Alcohol 24%–70% ABV limited to 5L. Over 70% ABV prohibited.
Electronics	Allowed. Power banks and loose lithium batteries MUST be in carry-on.	Allowed (must be powered OFF), but no loose lithium batteries or power banks.
Sharp Objects	Prohibited (except small scissors <4″ from pivot and plastic/round butter knives).	Allowed if sheathed or securely wrapped to prevent injury to handlers.
Medications	Allowed. Liquid meds can exceed 3.4oz; must be declared to officers.	Allowed. No restrictions. (Recommended to keep in carry-on for access).
Food	Solids allowed. Liquids/gels (peanut butter, yogurt) must follow the 3-1-1 rule.	Allowed. No restrictions on liquid or solid foods.
Tools	Limited. Must be 7 inches or less in length (non-sharp).	Allowed. No length limit.
Baby Items	Exempt. Formula, breast milk, and baby food allowed in “reasonable quantities” >3.4oz.	Allowed. No restrictions.
Self-Defense	Prohibited (includes pepper spray, brass knuckles, and stun guns).	Limited. One 4oz container of pepper spray is allowed if it has a safety mechanism.

TSA Liquid Rules for Checked Luggage: What You Need to Know

For standard liquids like water, soda, shampoo, or lotion, there is no 3-1-1 TSA limit on how much you can pack in a checked bag. You can pack a full-sized bottle of conditioner or a 2-liter bottle of olive oil without an issue.

The only limit is your airline’s weight limit (usually 50 lbs). Liquids are heavy, so watch those scales!

Items that are not permitted in checked luggage include flammable liquids, such as lighter fluid and paint; household chemicals like bleach and cleaning products; and pressurized items, including spray paint and fire extinguishers.

However, there are specific limits for “specialty” liquids:

Toiletries and Medicinal Aerosols

Toiletries: You can pack hairspray, deodorant, and shaving cream aerosols in checked bags.

The “Total Quantity” Rule: For medicinal or toilet articles (aerosols), the total capacity of all containers must not exceed 2 kg (70 oz) or 2 L (68 fl oz) per person. Every single container cannot exceed 0.5 kg (18 oz) or 500 ml (17 fl oz).

Prohibited: You cannot pack flammable liquids like gasoline, lighter fluid, or spray paint.

Alcoholic Beverages

Under 24% ABV (Wine and Beer): No limit. Pack as much as fits within your weight allowance.

24% to 70% ABV (Most Spirits): You are limited to 5 liters (1.3 gallons) per passenger. It must be in its original, unopened retail packaging.

Over 70% ABV (Grain Alcohol/140 Proof): Strictly prohibited. This is considered a fire hazard (flammable liquid) and is not allowed in checked or carry-on bags.

Prohibited Liquids

• Flammables: Paint thinner, gasoline, lighter fluid, and most non-medicinal aerosols (like spray paint or WD-40) are forbidden.
• Chemicals: Bleach, chlorine, and corrosive cleaners are not allowed.

Know What You Can & Can’t Bring On A Plane

Ask yourself these three questions. If the answer to any is “Yes,” it goes in your 3-1-1 bag:

• Can I spread this with a knife?
• Does it move if I tilt the container?
• Is it a mix of solids and liquids (like a can of soup)?

Solid shampoo and conditioner bars, soap bars, and balm sticks are excellent alternatives to traditional liquid products, as they are not classified as “liquids.” This means you can pack them outside the quart-sized bag required for liquids, effectively reducing the number of liquid items in your luggage.

Similarly, solid deodorants and toothpaste tablets offer the same convenience, allowing you to pack them freely without being subject to liquid restrictions, making them ideal for hassle-free travel.

Is Toothpaste A Liquid TSA?

Yes, toothpaste is considered a liquid by the Transportation Security Administration (TSA) and is subject to the same regulations as other liquids when traveling by air. Toothpaste must be in a container that is 3.4 ounces (100 milliliters) or less.

If you prefer, you can use solid toothpaste alternatives (like toothpaste tablets) that do not fall under the liquid restrictions.

Is Lotion Considered a Liquid?

Yes, lotion is classified as a liquid by the Transportation Security Administration (TSA). You can bring lotion on a plane, as long as you follow the 3-1-1 rule.

According to TSA regulations, certain items are prohibited in carry-on luggage to ensure safety during flights. Flammable liquids, such as lighter fluid and certain solvents, are prohibited. Additionally, most aerosol sprays beyond personal care products (like deodorant, hair spray, and shaving cream) are restricted.

Medically necessary liquids (prescription medications, baby formula, breast milk) are allowed in reasonable quantities but must be declared for inspection.

New TSA Rules For Travellers – What’s New In 2026 For US Travellers?

The biggest change travelers will notice in 2026 is the transition from analog to digital at the checkpoint.

Advanced CT (Computed Tomography) Scanners

By early 2026, over 90% of major U.S. hubs (like ATL, LAX, JFK, and ORD) will have replaced traditional X-ray machines with 3D CT scanners.

The Benefit: These machines create a 3D image that allows TSA officers to virtually “rotate” your bag’s contents.

At lanes equipped with these scanners, you no longer need to remove your liquids bag or your laptop from your carry-on. This does not mean you can bring a 12-oz water bottle. You still must follow the 3.4oz limit; you don’t have to fish the bag out of your luggage.

International Divergence

While the U.S. maintains the 100ml limit, 2026 marks a significant departure from the European and UK standards. Several major UK airports (Heathrow, Gatwick) have officially raised their liquid limit to 2 liters for departing passengers, thanks to these same scanners.

If you are flying internationally, always check your departure airport’s specific technology; you might be able to bring a full-size shampoo on the way back!

With the 2026 REAL ID requirements now in full effect, ensure your identification is compliant before you even worry about your shampoo. If you arrive with a non-compliant ID, you may face a $45 manual verification fee and significant delays.

What Is The Most Confiscated Item As Per TSA In 2026?

While exotic items often make the news, the most consistently confiscated category is oversized liquids and gels.

Did you know?
The well-known Magic 8 Ball often gets flagged at security checkpoints. Due to its substantial liquid content, it surpasses the 3.4-ounce carry-on limit and must be checked instead. Likewise, large snow globes, commonly bought as holiday mementos, are prohibited in cabins for the same reason. Additionally, toy weapons like foam swords or squirt guns are not allowed in carry-ons as they could be mistaken for banned items.

In 2026, the top three food-related confiscations were peanut butter, hummus, and jams. Travelers often forget that if you can “spread it,” it counts as a liquid and must follow the 3.4oz rule.

Every year, the TSA releases its “Top 10 Most Unusual Finds.” According to the most recent 2026 reports, the most confiscated “strange” items include:

Replica Explosives: Topping the 2026 list were realistic replica pipe bombs and fake C4 blocks found in a checked bag in Boise. Even though they were considered “training aids,” the TSA prohibits anything that resembles an explosive.

Live Animals: In a bizarre trend, turtles stashed in unconventional places were among the top unusual seizures at Newark and Miami.

Hidden Blades: “Spy gear” items, such as comb-knives, belt-buckle blades, and knives concealed in knee braces, were frequently detected by the new AI-powered CT scanners now common in 2026.

Ammunition in Snacks: One of the more creative (and failed) attempts included bullets hidden inside a container of Nesquik.

Can you take an e-cigarette on a plane? Electronic cigarettes with lithium-ion batteries are banned in checked luggage. Store them in carry-on bags, avoid in-flight use, and use a protective carry case.

Hand Tools: Screwdrivers, wrenches, and pliers are allowed in carry-on luggage only if they are seven inches or shorter when measured from tip to tip. Any hand tools that exceed this size, as well as all power tools, drills, and drill bits, need to be placed in your checked bags to prevent being flagged at security.

As of 2026, both the TSA and FAA continue to enforce strict regulations regarding cordless hair styling devices. Cordless curling wands and flat irons that contain gas or butane cartridges are not allowed in checked baggage due to potential fire hazards.

These items are permitted in carry-on luggage, provided they are equipped with a secure safety cover to prevent unintentional activation. Additionally, spare lithium batteries and portable power banks are completely prohibited in checked luggage; they must be kept with you in the cabin to allow for monitoring in case of overheating.

Engaging with the TSA through text can provide peace of mind, knowing that you’re making informed choices as you prepare for your journey. Happy Travels!
