TSA Toiletries Guide: What You Can (and Can’t) Bring in Your Carry-On

Because no one wants to unpack shampoo at security.

For travelers who live out of backpacks or carry-ons, navigating TSA rules about toiletries can be surprisingly stressful. From liquid limits to razor types, one misstep can slow you down — or cost you your favorite moisturizer.

This guide breaks down exactly what’s allowed in your carry-on, what needs to be checked, and how to pack smart to avoid spills, delays, or awkward bin searches.

The 3-1-1 Rule, Explained

TSA’s most important rule for toiletries is known as the 3-1-1 liquids rule:

• 3.4 oz (100ml) is the maximum size for each liquid or gel.
• 1 quart-sized bag is allowed per passenger.
• 1 bag per traveler.

Your liquids must all fit inside a single, clear, resealable quart-sized bag. That includes everything from lotion and sunscreen to toothpaste and lip gloss.

Examples of Liquids That Must Follow 3-1-1:

• Shampoo, conditioner
• Face wash
• Liquid foundation
• Hand sanitizer
• Perfume/cologne
• Deodorant (gel or roll-on)
• Toothpaste
• Creams or lotions

Tip: Even if a product looks solid, if it can pour, squeeze, spread, smear, pump, or spray — it counts as a liquid or gel.

What Can’t Go in Your Carry-On

Some items are completely banned from carry-ons, regardless of size:

• Aerosol sprays (except limited-size personal care sprays like dry shampoo)
• Large scissors or razors with exposed blades
• Flammable items (lighter fluid, certain aerosol sprays)
• Full-size liquids (over 3.4 oz, even if nearly empty)

What about razors?

• Disposable razors: Allowed
• Safety razors (blades exposed): Not allowed unless blade is removed
• Electric razors: Allowed

How to Pack Toiletries for TSA Success

TSA officers may ask you to remove your liquids bag for separate screening. Here’s how to keep it efficient and stress-free:

• Use a clear, zippered pouch instead of a plastic ziplock bag — it’s more durable and reusable.
• Pack the bag near the top of your carry-on so it’s easy to grab during screening.
• Pre-fill your liquids bag at home instead of scrambling at the airport.
• Group items by category: skincare, hygiene, makeup, etc.

Optional Hacks to Save Space

• Go solid when you can: Solid shampoo, conditioner, and lotion bars don’t count toward your liquid limit.
• Decant into travel-size bottles: Only bring what you need. A full-size 8 oz lotion isn’t worth the space.
• Share with a travel buddy: Split essentials if you're traveling with someone.

Recommended Tools

While the focus here is information, these products genuinely make TSA compliance easier:

• Multi-Compartment Toiletry Organizer
  Multiple zippered sections to separate liquids, solids, and tools. Water-resistant and flat-packing for tight luggage.

• Waterproof Travel Makeup Organizer
  Ideal for cosmetics or TSA liquids. Slim, structured, and easy to pull out at security.

Final Thoughts

Packing toiletries shouldn’t feel like a chemistry lab checklist. Know the rules, plan your kit, and travel with confidence.

Remember: TSA isn’t trying to make your life harder — they’re enforcing policies for everyone’s safety. A little preparation saves time, avoids embarrassment, and helps you breeze through security like a pro.
