The Top Five Items People Ask About: Razors, Batteries, Makeup, Shampoo & Deodorant

Tuesday, August 07, 2018
Top 5 Banner

1. Razors - There’s a lot of confusion out there as to what types of razors are OK to pack in your carry-on baggage. So people ask us about this one all the time.

  • 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.
  • Disposable Razors: Disposable razors come in two types. The kind that is completely disposable (handle and all), or the kind where you replace them with cartridges. These are permissible in carry-on luggage with the blade and replacement cartridges.
  • Electric Razors: Electric razors are permitted in both checked and carry-on bags.                                                

Different Types of Shaving Razors

2. Batteries - Whether they’re for business, health reasons, or leisure, we all travel with gadgets, and gadgets need batteries! Here’s a rundown of different types of batteries and whether they’re permitted or not. If you have any additional questions about batteries, please reach out to the FAA.

  • Batteries Allowed in Carry-on Bags:
    • Dry cell alkaline batteries; typical AA, AAA, C, D, 9-volt, button sized cells, etc.
    • Dry cell rechargeable batteries such as Nickel Metal Hydride (NiMH) and Nickel Cadmium (NiCad).
    • Jump starters with lithium ion batteries.
    • Lithium ion batteries (a.k.a.: rechargeable lithium, lithium polymer, LIPO, secondary lithium).
    • Consumer-sized lithium ion batteries [no more than 8 grams of equivalent lithium content or 100 watt hours (wh) per battery]. This size covers AA, AAA, 9-volt, cell phone, PDA, camera, camcorder, Gameboy, and standard laptop computer batteries.
    • Up to two larger lithium ion batteries (more than 8 grams, up to 25 grams of equivalent lithium content per battery) in their carry-on. This size covers larger extended-life laptop batteries. Most consumer lithium ion batteries are below this size. Lithium ion batteries that are between 101 – 160 wh are allowed in carry-on bags with airline approval.
    • Lithium metal batteries (a.k.a.: non-rechargeable lithium, primary lithium). These batteries are often used with cameras and other small personal electronics. Consumer-sized batteries (up to 2 grams of lithium per battery) may be carried. This includes all the typical non-rechargeable batteries for personal film cameras and digital cameras (AA, AAA, 123, CR123A, CR1, CR2, CRV3, CR22, 2CR5, etc.) as well as the flat round lithium button cells.
  • Batteries Allowed in Checked Bags:
    • Except for lithium batteries, all the batteries allowed in carry-on baggage are also allowed in checked baggage; however, we recommend that you pack them in your carry-on bag whenever possible. In the cabin, airline flight crews can better monitor conditions, and have access to the batteries or device if a fire does occur.
  • Prohibited Batteries:
    • Car batteries, wet batteries, or spillable batteries are prohibited from both carry-on and checked baggage unless they are being used to power a scooter or wheelchair. If you need to pack a spare battery for a scooter or wheelchair, you must advise the aircraft operator so the battery can be properly packaged for air travel.
    • Spare lithium batteries (both lithium metal and lithium ion/polymer) are prohibited in checked baggage.
  • Battery Chargers:
    • Lithium-Ion and Lithium-Polymer batteries are the most common rechargeable cell types found in Portable Chargers. Portable chargers are allowed in carry-on bags only.
    • External battery chargers/Power banks/Uninstalled or spare lithium ion batteries must be packed in carry-on bags.

3. Makeup

For many, traveling with makeup is just as important as traveling with batteries. You’ve just gotta have it. 

  • Makeup in a solid or powder form is allowed in carry-on and checked bags with no quantity or size limitations. However, when packed in carry-on bags, makeup in a liquid, lotion, gel, paste or creamy form, must be in containers that are 3.4 ounces or less. You can take as many travel-sized liquids as you can comfortably fit into one quart-sized, zip-top bag. One liquids bag is allowed per passenger in carry-on bags. We don't limit the size or quantity of liquids in checked bags.

4 & 5. Shampoo & Deodorant

You’ve got to smell nice and keep your hair shiny, so it’s not surprise that many people ask about shampoo and deodorant.

  • Shampoo/Conditioner and deodorant must be in containers that are 3.4 ounces or less in carry-on bags. You're allowed to take as many travel-sized liquids as can fit into a single quart-sized, zip-top bag. One bag is allowed per passenger in carry-on. Larger containers of such items must be placed in checked bags. Solid and powder deodorant are allowed in carry-on bags and aren't limited in size.

It's been over a decade of the liquids farce and you still can't provide a single independent, peer-reviewed study that supports 3.4-1-1. Why can't you admit you panicked and over-reacted and it's time to stop pretending liquids are at all dangerous?

Submitted by SSSS For Some Reason on

My favorite... the 3-1-1 nonsense. This 20 ounce bottle of liquid is too dangerous to go through security. This 20 ounce bottle of liquid that is so dangerous it can't go through security is just going to get tossed into a common rubbish bin.

These seven small bottles, each at three ounces, in a zippy bag, are perfectly fine to go through security. And that empty thirty ounce container in the bag... pay it no attention because it's empty. And then once through security you pour all twenty one ounces of liquid into the big bottle thereby negating, entirely and completely, the 3-1-1 nonsense.

Yes, I completely agree that we are not safe as long as the troublemakers are flying. Let's hope that Homeland Security employs enough intelligent people with plenty of imagination. They surely do... so let's get to work and use common sense!

Size is limited per container due to the amount needed to create dangerous materials. Follow the law or drive.

what Is the logic of limiting to 3 ounces each container. My lotion of 4 ounces wasn’t even questioned or confiscated but my shampoo and conditioner if 8 ounces was taken and thrown away. Please explain.

Submitted by Anonymous on

And why do we have to find loop holes in order to take our favorite shampoo and conditioner with us when we are traveling. Please revisit this ridiculous limitation of 3 ounces.

Submitted by LS on

This page says "Makeup in a solid or powder form is allowed in carry-on and checked bags with no quantity or size limitations." But in the next item it says shampoo and deodorant needs to be in the ziplock for passing through in a carry-on. I am thinking of deodorant or anti-perspirants in a stick form. Isn't that the same as a solid? Why would that need to go into the ziplock?? I don't travel enough to remember what I've done in past recent years, but does a deod/anti-pers. stick really need to go into the ziplock? Thank you for answering. We are traveling on Saturday.

I would like to carry on a succulent planted in the bottom half of a wine bottle. Is that allowed. I’m concerned they could rule the wine bottle is sharp and could be used as a weapon?

No. It isn't.

One sixteen ounce bottle is prohibited.

Seven three ounce bottles are allowed.

How can twenty-one ounces be safe when sixteen ounces is dangerous?

It liquid volume has anything to do with it there would not be any 3-1-1 rules.

And if flying with liquids is too much for you perhaps you should switch to driving.

I’m having knee replacement surgery and will need to keep the knee iced during my flight. What ice packs are allowed?

Doesn't matter what the answer is the agents at the checkpoint have been given 'discretion' to make up the rules as they go along.

What happens if I drop my ziplock bag, my 3oz bottles break, and the liquids pool in the bag. Can I still bring it if it isn't contained in my 3oz containers anymore?

Submitted by Rich Winslow on

I will be traveling quite a bit for my work, I run a pool cleaning business, and I will be carrying a fair amount of chemicals and PH balancers, etc, from time to time if I am coming back from a trade show or if I am going to see a large industrial client away from my home area. What sort of restrictions would I have from being allowed to carry anything on? Is it best to either ship the chemicals via UPS or FedEx ahead of time, or just pack them in checked luggage? I want to be sure I don't violate any regulations, but still want to find the most affordable way to transport my materials I need.

Rich sez - "I will be traveling quite a bit for my work, I run a pool cleaning business, and I will be carrying a fair amount of chemicals and PH balancers, etc"

Welcome Rich, most of the chemicals used in pool maintenance (chlorine, etc) are listed as hazardous materials, or not allowable on the plane in either checked baggage or carryon bags. If you have specific chemicals, you can use the What Can I Bring Tool to check. I hope this helps you reach an informed decision.
