Liquids, Aerosols and Gels (LAGs), Restricted Articles and Dangerous Goods

All departing passengers are required to have both their boarding pass and travel documents ready for inspection by airport security personnel upon entering the Departures Hall. Security measures are also in place at the airport. To avoid unnecessary delay, make sure that you read in detail the requirements as stated in Liquids, Aerosols and Gels (LAGs), Restricted Articles and Dangerous Goods and follow the instructions accordingly when you pack your baggage.

Any items which are found not carried in compliance with the said requirements will be removed.

Starting 1 March 2019 , Macau International Airport and heliport will implement new aviation security requirements for the following articles:

The carriage of isopropyl alcohol etc. on aircraft

Rubbing alcohol, isopropyl alcohol and disinfecting wipes etc., even if the percentage of alcohol by volume is 70 percent or more, belong to non-radioactive medicinal articles (including aerosols) and can be transported by passengers on board an aircraft either in carry-on or checked baggage. Passengers must comply with the following requirements when transporting these items:

Note: Airlines may impose more stringent rules on the carriage of the above items in accordance with their own operation policies. It is advisable that passengers consult their airlines for information prior to their trips.

To prevent the introduction onto an aircraft of weapons, explosives or articles likely to be utilized to commit an act of unlawful interference or to avoid articles or substances which are capable of posing significant risk to health, safety or property when transported by air, the following measures are imposed on departing passengers of Macau International Airport.

Liquids, Aerosols and Gels (LAGs)

The following screening procedures are implemented for the carriage of liquids, gels and aerosols in the hand carry baggage in Macau International Airport:

  1. All liquids, aerosols and gels must be carried in containers not greater than 100 ml (or the equivalent in other volumetric measurements, e.g. fluid ounces). Liquids carried in a container larger than 100 ml are not accepted, even if the container is only partly filled.

  2. Containers must be placed in a transparent re-sealable plastic bag of a maximum capacity not exceeding 1 litre. The containers must fit comfortably within the transparent plastic bag, which should be completely closed.

  3. The plastic bag must be presented for visual examination at the screening point. Only one transparent plastic bag per passenger should be permitted.

  4. To facilitate screening and avoid a cluttered x-ray image, such plastic bag containing liquid containers should be presented apart from other cabin baggage, coats and jackets or laptops for separate x-ray screening.


  1. Medications under prescription, baby milk/food and special dietary requirements are allowed. When carrying these types of food, the passenger must present an appropriate and proportionate means of verifying the nature of such liquids to the security personnel.

  2. Liquids can be purchased either at airport duty free shops, or on board aircraft, on the condition that the liquids are packed in a sealed plastic bag that is both tamper-evident and displays satisfactory proof of purchase at airport duty free shops, or on board aircraft, on the day(s) of the journey for departing as well as transfer passengers.

Dangerous Goods

Dangerous goods are articles or substances that are capable of posing a risk to health, safety, property or the environment when transported by air. There are many everyday items which seem harmless but can be a threat to the safety of passengers and crew when they are brought on an aircraft; hence they are often forbidden to be carried by passengers either in the aircraft cabin or their baggage. These dangerous goods are classified by International Civil Aviation Organization (ICAO) into 9 classes as follows:

Class 1 Explosives
Class 2 Gases
Class 3 Flammable liquids
Class 4 Flammable solids; substances liable to spontaneous combustion; substances in which, contact with water, emit flammable gas
Class 5 Oxidizing substances and organic peroxides
Class 6 Toxic and infectious substances
Class 7 Radioactive materials
Class 8 Corrosive substances
Class 9 Miscellaneous dangerous goods (e.g. lithium batteries)

Requirements for the carriage of lithium batteries by air (Wh = Watt hour = Ampere Hour x Voltage)

  1. Electronic devices (e.g. laptop computers, cellular phones, cameras, camcorders and so on) or portable medical electronic devices containing lithium metal batteries not exceeding 2 grams or lithium ion batteries not exceeding 100 Wh can be carried both in carry-on baggage or checked-in baggage. All spare batteries must be put in carry-on baggage.

  2. For electronic devices or portable medical electronic devices containing lithium metal batteries exceeding 2 grams but not exceeding 8 grams or lithium ion batteries exceeding 100Wh but not exceeding 160 Wh, OR if for health reasons or other special reasons mobility aids (e.g. wheelchairs) that are powered by lithium batteries must be carried during the travel, passengers must make the request to the airline. With the approval of the airline, passengers can then follow the instructions given by the airline to put the devices in carry-on baggage or checked-in baggage.  However, all spare batteries must still be put in carry-on baggage.

ICAO has specific shipping and packing requirements for the above dangerous goods. Passengers should therefore be aware that airlines and security screening agencies reserve the right to limit or forbid the carriage of these items in the interests of aviation safety.

If in doubt, ask!

Common substances found in homes - things such as pesticides, petrol, paint, mineral turpentine, methylated spirit, gas cylinders, oven and drain cleaners, bleach, glues and aerosols – are potentially dangerous goods.

If you are planning to carry some common household items, check to see whether there is a hazardous symbol on the packaging.


If there is, ask yourself “Do I really need to take it? Or, can I buy it when I get there instead?”. If you are still not sure, please contact the airline you are flying with.
