Liquids are allowed in checked baggage, but they must follow TSA size and quantity rules

You can bring liquids in your checked luggage on domestic and international flights. The rules are much more relaxed than for carry-on bags — there is no 3.4-ounce limit per container, and you can pack as many liquid containers as fit inside your suitcase. However, certain liquids are still banned entirely, and some are restricted by quantity or packaging.

The key difference from carry-on rules is that checked bags go through different screening. TSA officers can open and inspect them, so they have more time to verify what you are packing. That said, airlines and the federal government still prohibit hazardous materials in checked luggage for safety reasons — mainly because the cargo hold is not pressurized the same way the cabin is, and a leak or spill down there is harder to manage.

Key Takeaways

  • Common liquids like shampoo, conditioner, lotion, and toothpaste can go in checked bags with no size limit per container.
  • Alcohol under 70% ABV (alcohol by volume) is allowed in checked luggage up to 5 liters total per passenger, but alcohol 70% ABV or higher is banned entirely.
  • Flammable liquids such as perfume, nail polish, paint thinner, and lighter fluid are prohibited in both carry-on and checked bags.
  • Gels, pastes, peanut butter, and other thick substances follow the same rules as liquids, so they are allowed in checked bags without size limits.
  • Pack liquids in a sealed, leak-proof container and place them in a plastic bag inside your suitcase to prevent damage to your clothes if a container leaks.

What liquids are allowed in checked bags

Most everyday toiletries and personal care items are fine in checked luggage. This includes shampoo, conditioner, body wash, lotion, moisturizer, sunscreen, toothpaste, mouthwash, and deodorant. You can also pack hair gel, styling products, face masks, serums, and other cosmetics. Since there is no per-container size limit, you can bring full-size bottles of anything you use regularly.

Food items that are liquid or gel-like are also allowed — this includes peanut butter, honey, jam, yogurt, sour cream, and other spreads or sauces. Beverages like juice, wine, and beer are permitted as long as they meet alcohol rules (see below). You can also pack medicine in liquid form, such as cough syrup or liquid vitamins, without restriction.

Alcohol rules for checked luggage

Alcohol is allowed in checked bags, but the rules depend on the strength. Beverages with 24% to 70% alcohol by volume (ABV) — which includes most wines and spirits — are limited to 5 liters total per passenger. You must pack them in your checked bag only; they cannot go in carry-on. Beer and wine coolers, which are typically under 24% ABV, have no limit.

Alcohol that is 70% ABV or higher is banned entirely from both checked and carry-on luggage. This includes most hard liquors like grain alcohol, Everclear, and some high-proof whiskeys and rums. Check the label on any bottle you plan to pack — if it says 70% ABV or above, you cannot bring it on the plane.

Some airlines have their own stricter rules on top of TSA rules, so check your airline's website before packing. International flights may have different limits depending on your destination country, so research that as well.

Liquids that are completely banned

Certain liquids are prohibited in checked luggage no matter what. These include flammable liquids like perfume, cologne, nail polish, nail polish remover, paint thinner, turpentine, lighter fluid, and gasoline. Even small amounts are not allowed because they pose a fire risk in the cargo hold.

You also cannot pack aerosols that contain flammable propellants — this includes spray paint, spray adhesive, and some air fresheners. Check the label; if it says "flammable" or lists a flammable propellant, leave it at home or buy a new one at your destination.

Other banned items include bleach, drain cleaner, pesticides, and other corrosive or toxic chemicals. If you are unsure whether something is banned, check the TSA website or contact your airline before you pack.

How to pack liquids safely in checked luggage

Use containers that are sealed and leak-proof. Bottles with screw caps are usually fine, but test them first — fill a bottle partway with water, seal it, and turn it upside down to make sure nothing leaks. If you are packing expensive or irreplaceable items, consider buying travel-size containers or transferring liquids to smaller bottles.

Place all liquid containers in a clear plastic bag or zippered pouch inside your suitcase. This creates a second barrier if a container leaks, protecting your clothes and other belongings. Pack the bag in the center of your suitcase, surrounded by soft items like clothing, rather than near the edges where pressure from handling might crack a bottle.

If you are traveling internationally, wrap each bottle in a plastic bag individually as well. Some countries have stricter rules about liquid packaging, and double-bagging shows you took precautions.

International travel and checked liquids

Rules vary by country and airline. The United States allows the amounts described above, but if you are flying to or from another country, that country's aviation authority may have different limits. For example, some European airlines restrict alcohol to smaller quantities, and some countries ban certain cosmetics or medications entirely.

Check your destination country's customs rules before you pack. Some countries do not allow you to bring in certain medications or cosmetics, even if they are legal in the United States. Your airline's website will have a link to country-specific rules, or you can contact the embassy of your destination country.

What happens if you pack a banned liquid

If TSA finds a banned liquid during baggage screening, they will remove it and dispose of it. You will not be charged, but you will lose the item. Your bag may be opened and inspected, and a notice will be left inside explaining what was removed.

If a banned item is discovered after you have already checked your bag, you may be prevented from boarding, or your bag may be pulled from the flight. In rare cases, packing a hazardous material intentionally can result in fines, so it is worth double-checking before you pack.
