Travel Liquids & Cosmetics: How to Pack Your Bags Without Getting Stopped

The 100ml Rule: Mastering Liquid Restrictions for International Travel

Liquid restrictions have been a constant headache for travelers since 2006. While technology is slowly improving, the '3-1-1' rule remains the global standard for most international airports. Getting it wrong often means throwing away expensive skincare or perfumes right at the gate.

1. Breaking Down the 3-1-1 Rule

• 3.4 Ounces (100ml): Each container must be 100ml or less. Important: This applies to the container size, not the liquid inside. A 200ml bottle with only 10ml of lotion will be confiscated.
• 1 Clear Bag: All 100ml bottles must fit into a single 1-quart size, clear, resealable plastic bag (approx. 20cm x 20cm).
• 1 Bag Per Person: Only one bag is allowed in your carry-on.

2. What Counts as a Liquid? (The Security Definition)

It's not just water. TSA and other security agencies define 'liquids, aerosols, and gels' broadly:

• Pastes: Toothpaste, mascara, foundation.
• Gels: Shampoo, hair gel, lip gloss.
• Spreads: Peanut butter, jam, soft cheese.
• Sprays: Deodorant, hairspray, sunblock. Cosmetics Carry-on Rules

3. The Exemptions: When the Rules Don't Apply

• Medications: Liquids like insulin or saline solution are allowed in larger quantities. Declare them to the officer beforehand. Medication Rules
• Infant Food: Breast milk, formula, and baby food are exempt if traveling with an infant. Expect extra screening.
• Duty-Free: Liquids over 100ml bought in the duty-free area are allowed IF kept in a sealed Security Tamper Evident Bag (STEB) with the receipt visible.
