Aviation Security: Compliance with the international 100ml LAGs liquid rule in cabin baggage screening.
⚑ Executive Security Mandate:

Under ICAO aviation security standards, passengers can carry liquids, aerosols, and gels (LAGs) in cabin hand baggage only in containers of 100 ml (3.4 oz) or less, all enclosed within a single transparent, resealable 1-liter plastic pouch. Containers exceeding 100ml (even if half-empty) will be confiscated at the security X-ray checkpoint. Baby formula and prescription medicines are exempt.

০১ The 3 Core Rules

1. The 3 Core Conditions of the International 100ml LAGs Rule

  1. Max Container Capacity 100ml: The container capacity itself must not exceed 100 ml. A 200ml bottle with only 50ml of liquid inside will be confiscated.
  2. 1-Liter Clear Resealable Pouch: All 100ml containers must fit comfortably inside a clear, transparent, resealable plastic bag (approx. 20 x 20 cm).
  3. One Bag Per Passenger: Each passenger is permitted only one 1-liter liquid bag, which must be presented separately for X-ray screening.
০২ What Counts as a Liquid?

2. What Classifies as a 'Liquid' Under Security Screening?

Aviation security treats gels, pastes, lotions, and pressurized aerosols as liquids:

  • Toiletries & Cosmetics: Toothpaste, shaving foam, hair gel, perfumes, lip gloss, moisturizers, mascara, and liquid foundation.
  • Oils & Foods: Mustard oil, ghee, honey, jams, peanut butter, yogurt, and curry sauces.
  • Pressurized Sprays: Deodorants, hairspray, and body mists.
০৩ Carrying Large Bottles

3. How to Transport Large Bottles of Oil, Ghee & Liquids

Bottles of 500ml or 1 liter cannot be carried into the airplane cabin. To safely transport them in checked baggage:

  • Avoid glass bottles; transfer liquids into durable food-grade plastic containers.
  • Wrap the bottle neck with electrical tape or Teflon plumber's tape to prevent screw-cap loosening.
  • Double-seal the container in two separate heavy-duty zip-lock plastic bags.
  • Place the sealed package in the center of your suitcase surrounded by soft clothes for impact cushioning.

Cabin Baggage Liquid Security Protocols: 100ml Containers, STEBs & Exceptions

The International Civil Aviation Organization (ICAO) and aviation security agencies across the globe strictly enforce the Liquids, Aerosols, and Gels (LAGs) standard to prevent liquid explosives from entering passenger aircraft cabins. Understanding these exact volumetric specifications ensures smooth processing at airport security checkpoints.

Exact Security Parameters for Carry-On Liquids:

  • Container Capacity Restriction (100ml Rule): The security rule applies to the physical volume capacity of the container, NOT the remaining contents inside. A 200ml bottle containing only 50ml of shampoo will be confiscated immediately because the container capacity exceeds 100ml.
  • One-Liter Transparent Bag: All 100ml liquid containers must fit comfortably inside a single, transparent, resealable clear plastic bag (maximum dimensions: 20cm x 20cm / 1 liter capacity). Each passenger is legally restricted to one clear plastic bag.
  • Security Tamper-Evident Bags (STEBs): Liquids, perfumes, and liquor purchased at airport duty-free shops after passing security screening must remain sealed inside official STEB bags with the purchase receipt visibly attached until you arrive at your final destination. Breaking the seal before transit screening results in confiscation.
  • Baby Food & Medical Liquid Exemption: Infant formula, breast milk, sterilized baby water, and essential prescription liquid medications are legally exempt from the 100ml limit. However, you must present these items separately to the security screener for visual and explosive trace detection (ETD) verification.
Security Screening Checklist: Remove your clear plastic bag containing liquids from your cabin backpack and place it in a separate plastic tray before passing through the X-ray archway. Keeping liquids hidden inside your backpack triggers manual search bag re-scans.
