Rules and Tips for Bringing Liquids in International Checked Baggage

Bringing liquids in your luggage for an international trip is pretty common, whether it’s toiletries, souvenirs, or local products from your destination. But the rules around it can still be confusing. Is everything limited to 100 ml? Are some liquids completely banned? To keep your trip smooth and your luggage in good shape, here’s the guide to help you pack liquids the right way.

Liquid Restrictions for International Flights

Many people mistakenly think the 100 ml liquid limit applies to all types of luggage. In reality, this rule only applies to carry-on baggage. According to Indonesia’s aviation regulation SKEP/43/III/2007, which follows international standards set by the ICAO (International Civil Aviation Organization), passengers may carry liquids, aerosols, and gels (often called LAGs) in the cabin if they meet these requirements.

• Each container must not exceed 100 ml
• All containers fit into one clear, resealable plastic bag (max size: 30 x 40 cm, total volume: 1 liter)
• Each passenger is only allowed one bag

Most major international airlines follow the same rules for carry-ons. But when it comes to checked luggage, the 100 ml limit doesn’t apply. You’re free to pack liquids in containers larger than 100 ml, as long as they’re not considered hazardous or restricted based on airline or aviation regulations. Just be sure to seal them properly to avoid leaks that could damage your clothes or other items in your luggage.

Liquids You’re Allowed to Bring and What to Avoid

Most everyday liquids are fine to bring in checked luggage, but there are some limits, mainly for safety reasons. Here’s a quick breakdown of what’s generally allowed and what you’re better off leaving behind.

Liquids That Are Generally Allowed

• Toiletries and personal care: Shampoo, conditioner, body wash, lotion, toothpaste, non-aerosol deodorant, perfume, essential oils
• Medications: Liquid meds like cough syrup, eye drops, or insulin (bring a prescription if possible)
• Food and drinks: Water, juice, baby food, formula (in reasonable quantities), sauces, jam, honey, soft drinks
• Alcohol: Often allowed with restrictions. Typically, alcohol under 70% volume is permitted, with a total limit of 5 liters per person for alcohol between 24%-70% ABV
• Other essentials: Contact lens solution, cleaning liquid

Liquids You Should Avoid or Are Not Allowed

• Flammable substances: Gasoline, paint thinner, spray paint (some small containers may be allowed under specific guidelines), lighter fluid
• Hazardous chemicals: Pesticides, herbicides, strong acids or bases, radioactive materials, and high-concentration bleach
• Gas canisters: Large aerosol cans or gas cartridges for camping stoves
• Poorly packed items: Fragile or loosely closed bottles that could leak or break easily

Always check your airline’s and destination country’s list of banned or restricted items. The rules may vary, so it’s best to double-check on their official websites before packing.

Liquid Allowances for Checked Baggage

Even though the 100 ml rule doesn’t apply to checked baggage, that doesn’t mean you can bring as much liquid as you want. There are still a few important things to keep in mind to avoid any issues during check-in or when going through customs at your destination.

One of the biggest things to watch out for is your baggage weight. Packing large bottles of liquid can quickly add up and push your luggage over the airline’s weight limit. If that happens, you might end up paying extra fees for overweight baggage.

Customs rules are another thing travelers often overlook. Many countries have their own limits on how much liquid you’re allowed to bring in without having to declare it or pay tax, especially when it comes to alcohol. It’s always a good idea to check the customs policy for your destination before you fly.

If you’re bringing duty-free alcohol, don’t forget to keep the receipt. You might need to show it during airport security checks or when entering another country. This helps prove that your purchase is legal and within the allowed limit.

While there’s no strict limit on how big each container can be in your checked bag, it’s still better to pack liquids carefully and responsibly. That way, you can avoid any unnecessary hassle and enjoy a smoother travel experience.

Tips for Packing Liquids Without Leaks or Damage

When you’re packing liquids in your luggage, preventing spills and protecting your other belongings should always be a top priority. These simple tips will help you pack liquids safely and avoid any mess during your trip.

Choose Durable and Leakproof Containers

Use bottles or containers made from sturdy materials that won’t easily crack or break. Travel-size bottles are ideal since they’re compact and reduce the risk of breaking during transit.

Seal Bottles Securely

Make sure each cap is tightly closed. For extra protection, place a layer of plastic wrap over the opening before screwing the lid on. This helps prevent leaks caused by air pressure changes during flights.

Use Ziplock Bags for Extra Protection

Place each container in its own ziplock bag. If anything leaks, the spill stays contained and won’t ruin your clothes or other items in your luggage.

Wrap Bottles with Soft Layers

Use clothes, towels, bubble wrap, or other soft items to wrap each bottle. This adds a protective cushion and helps prevent breakage during baggage handling.

Pack Liquids in a Safe Spot Inside the Luggage

Place your wrapped bottles in the center of the luggage, surrounded by softer items for added protection. Avoid putting them near the edges or corners, where they’re more exposed to impact.

Stay Organized with Packing Cubes

Packing cubes help keep everything neat and separated. You can store liquids away from clothes and valuables, while the compression feature saves space and keeps your luggage tidy.

Bringing liquids in your checked luggage for international travel doesn’t have to be stressful. As long as you know the rules, follow airline and destination guidelines, and pack carefully, you can avoid leaks and damage with ease.

With the right preparation, you can enjoy a smoother, worry-free journey. For added convenience, try using compression packing cubes. They help keep your belongings organized, separate liquids from other items, and reduce the risk of spills. For a more efficient packing experience, explore Baller All-Day Compression Packing Cubes.
