Can You Bring Hand Sanitizer on a Plane? 100ml Rule

Yes, you can bring hand sanitizer on a plane — but it counts as a liquid, which means the standard 100ml carry-on liquid rule applies. The bottle must be 100ml or smaller, and it must go in your clear 1-litre liquids bag along with your other liquids and gels. Larger bottles have to go in your checked bag.

Hand Sanitizer Is a Liquid — The 100ml Rule Applies

Whether your hand sanitizer is a gel, liquid, or spray, it is subject to the standard airport liquids rule in the US, EU, and UK:

• The container must hold 100ml or less (this is the container size, not the amount of product inside)
• All liquids must fit in a single transparent resealable plastic bag of approximately 1 litre capacity
• Each passenger is allowed one liquids bag

A 30ml, 50ml, 75ml, or 100ml bottle of hand sanitizer is allowed in carry-on. A 200ml, 300ml, or 500ml bottle is not — those must go in your checked luggage.

Gel vs. Spray: Same Rules Apply

Both gel hand sanitizer and spray hand sanitizer count as liquids under airport security rules. The format does not change the rule. A 100ml spray hand sanitizer must go in your liquids bag alongside a 100ml gel hand sanitizer. Neither format has any special exemption.

The COVID-Era Exemption Is Over

During the COVID-19 pandemic in 2020 and 2021, the TSA temporarily allowed a single bottle of hand sanitizer up to 12 oz (355ml) in carry-on bags — roughly triple the normal limit. This exemption was introduced as an emergency public health measure and has since ended. Normal 100ml limits now apply in the United States.

The same applies internationally. No major aviation authority currently maintains a hand sanitizer exemption above the standard 100ml limit.

If you read older articles that mention the 355ml allowance, that information is outdated. The rule today is 100ml, full stop.

UK Rules

In the UK, the hand sanitizer rule mirrors the EU and US approach: containers must be 100ml or smaller and must be placed in a single transparent resealable bag. Each passenger is permitted one such bag. Full-size hand sanitizer bottles must go in the hold.

EU Rules

EU airports apply the same liquid restriction: containers of 100ml or smaller, all placed in a single transparent resealable bag of no more than 1 litre capacity, one bag per person. This applies at all EU airports including those operated by budget airlines such as Ryanair and easyJet.

What to Do With a Large Bottle

If you have a 250ml or 500ml bottle of hand sanitizer and want to bring it on a trip:

1. Check it: put the large bottle in your checked luggage — no restrictions apply to hand sanitizer in the hold
2. Decant it: pour a travel-size amount into a reusable 100ml bottle or silicone travel bottle before you fly, and leave the large bottle at home
3. Buy travel-size: many brands sell hand sanitizer in 30ml, 50ml, and 100ml sizes specifically designed for travel. Stock up before a trip.

Hand sanitizer is also widely sold at airport pharmacies and convenience stores after security, and it is easy to find at most destinations. You do not need to bring a large supply on the plane.

Tips for Carrying Hand Sanitizer Through Security

• Keep it accessible: your liquids bag must be removed from your carry-on and placed in a security tray for X-ray. Keep your hand sanitizer in the liquids bag rather than loose in your bag.
• Check the size: double-check the volume printed on the bottle before you pack. Many pump bottles are sold in 200ml sizes and will not be allowed through.
• Refill before you fly: if you use a reusable travel bottle, fill it from your large home bottle the night before you travel rather than carrying the large bottle to the airport.
• Alcohol content: high-alcohol hand sanitizers (most are 60–70% alcohol) are not classified as flammable liquids for aviation purposes and are treated like any other liquid.
