According to TSA regulations, you can bring vape juice on a plane in both your carry on and checked bags.

But there are restrictions if you pack vape juice in your carry on – and if you’re flying internationally, there are definitely a few things you must know.

Can You Bring Vape Juice on a Plane?

Carry on Bags

You can pack vape juice in your carry on, but only in containers that are no larger than 3.4oz/100ml.

This is due to the TSA’s 3-1-1 Rule that prohibits passengers from bringing any liquids (as well as gels and aerosols) in their carry on in containers larger than 3.4oz/100ml.

If the bottle of vape juice you want to bring in your carry on exceeds this limit, it will be confiscated by a TSA agent.

Checked Bags

You can bring vape juice on a plane in your checked bags with no quantity limits.

Even if your bottles of vape juice don’t exceed 3.4oz/100ml, we still recommend packing them in your checked bags because you will only be able to fit approximately 25 ounces or 7-8 bottles of 3.4oz/100ml liquids, gels, and aerosols in your carry on, which includes all your other toiletries.

Can You Bring Vape Juice on International Flights?

Whether you can bring vape juice on an international flight depends on where you are flying to.

Many countries around the world have restrictions on vaping products, with some countries not allowing you to vape in public while others outright banning vaping products altogether.

While this doesn’t necessarily mean that you won’t be able to bring your vape and e-liquid into the country, finding supplies like batteries and vape juice could be impossible depending on the legality of vape products in the country you are flying to.

The following countries have some of the strictest regulations in the world when it comes to vaping.

  • Australia: E-liquid containing nicotine is illegal to sell or import.
  • Argentina: The sale, importation and manufacturing of e-cigarettes is banned in Argentina.
  • Brazil: The sale and importation of e-cigarettes is illegal in Brazil.
  • China: Non-tobacco flavored e-cigarettes are banned from sale in China
  • Hong Kong: The sale or possession of nicotine-based e-cigarettes is illegal in Hong Kong
  • India: There is a ban on the sale and production of e-cigarettes in India.
  • Iran: The sale or distribution of e-cigarettes is illegal in Iran.
  • Japan: E-cigarettes containing nicotine are banned unless the e-cigarette is registered as a medicinal product.
  • Nicaragua: In Nicaragua, vaping products are completely banned.
  • Singapore: It is illegal to possess, purchase and use vaporizers in Singapore.
  • Thailand: Thailand has banned e-cigarettes since 2014.

Can You Bring Nic Salt on a Plane?

You can bring nic salt on a plane in both your carry on and checked bags, though if packed in your carry on, any bottle must not exceed 3.4oz/100ml.

How to Pack Vape Juice for Air Travel

There are only a few things you need to keep in when bringing vape juice on a plane.

  • If any of your e-lqiuid or nic salt bottles are larger than 3.4oz/100ml, make sure that you only pack them in your checked bag.
  • If your e-liquid or nic salt bottles are less than 3.4oz/100ml, place them inside a clear resealable bag along with your other liquids, gels, and aerosols.
  • When going through airport security, take this bag out and place it in a screening bin.
  • Cabin pressure can cause bottles to expand, so it can be a good idea to only take partially used bottles that have some unused space at the top.
