The Transportation Security Administration (TSA) has specific rules and guidelines for various items, including canned goods. While TSA regulations allow travellers to bring canned goods in their luggage, there are certain restrictions and considerations to keep in mind. These restrictions primarily revolve around the TSA's 3-1-1 rule for liquids, which limits the volume of liquids that can be carried through security checkpoints. Understanding the regulations surrounding canned goods is essential for travellers to ensure a smooth and stress-free airport experience.

What You'll Learn

Canned goods are allowed in checked bags
Canned goods are typically allowed in checked bags when flying. However, it is worth noting that they are usually subject to the TSA's 3-1-1 rule, which states that passengers are only allowed to bring liquids, gels, and aerosols in containers of 3.4 ounces or less. As most cans exceed this volume, they may require additional screening and could even be prohibited from passing through the checkpoint.
To avoid any issues, it is recommended that canned goods be packed in checked luggage or shipped to your destination. This is especially important if the cans may appear tampered with or pose security concerns, as they may be prohibited by the TSA officer at the checkpoint.
It is also important to be aware that the rules and regulations regarding what you can bring into a country differ from those of the TSA. For example, when entering the United States, your bag may be screened by customs, and certain products may be prohibited or require declaration. Therefore, it is essential to check the latest regulations and restrictions of your destination country to ensure compliance.
Additionally, while some foods, such as hard cheese, frozen seafood, and fresh eggs, are allowed in carry-on bags, others, such as baby food, baby formula, and juices, are only permitted in carry-on luggage if they undergo special screening. As such, it is always a good idea to plan and pack properly to facilitate the screening process and ensure a smooth travel experience.

They're subject to the 3-1-1 rule for liquids
Canned goods are typically allowed to be transported in checked bags. However, they are usually subject to the Transportation Security Administration's (TSA) 3-1-1 rule for liquids. This rule states that travellers are allowed to bring liquids in containers with a capacity of 3.4 ounces or less, in a 1-quart-sized, clear plastic, zip-top bag, and one bag per passenger is allowed. Most cans exceed this volume, so they would require additional screening. It is best to check them in or ship them home.
The 3-1-1 rule also applies to creamy or spreadable items, such as salsa, creamy cheese, dips, peanut butter, jams, and preserves, as they have a gel-like consistency. These items are allowed in checked luggage but must be in containers smaller than 3.4 ounces to be carried on.
Baby food, baby formula, and juices are allowed in carry-on bags but will need to undergo a special screening. Water for babies, in reasonable quantities, is also permitted in carry-on baggage.
It is important to note that even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm, appears tampered with, or raises security concerns. The final decision on whether an item is allowed rests with the TSA officer at the checkpoint.

Cans over 3.4 oz. require additional screening
Canned goods are allowed to be flown in checked bags, but they are usually subject to the TSA's 3-1-1 rule. This rule applies to liquids, gels, and aerosols, and any item that falls under this rule must be in containers of less than 3.4 ounces to be carried onto the plane. Since most cans are more than 3.4 ounces, they would require additional screening.
Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns. The TSA has a list of foods that are allowed and not allowed to be flown with on its website, but the final decision rests with the TSA officer at the checkpoint.
If you are unsure whether your canned goods will be allowed, you can contact the AskTSA team for assistance. They are available 365 days a year, and live assistance is available from 8 am to 6 pm ET. It is always better to check beforehand than to have to throw out your purchases at the airport.

TSA officers have final say on items
Canned goods are typically allowed to fly in checked bags. However, they are usually subject to the TSA's 3-1-1 rule, which states that most liquids, gels, and aerosols must be in containers of 3.4 ounces or less. Since most cans exceed this volume, they may require additional screening and could be prohibited from passing through the checkpoint.
The Transportation Security Administration (TSA) has stringent rules regarding prohibited items, and even if an item is generally permitted, it may be subject to additional screening or prohibited if it triggers an alarm, appears tampered with, or poses security concerns. Ultimately, the final decision rests with the TSA officer at the checkpoint, who may use their discretion to allow or deny an item.
TSA officers are trained to make these decisions based on security concerns and X-ray images of items. They may request that you submit your items for additional screening or place them in checked luggage. As such, it is advisable to pack canned goods in checked bags or ship them to your destination to avoid potential issues at the checkpoint.
While the TSA has guidelines, each officer may use their judgment when inspecting items. They may consider factors such as the appearance of the can on X-ray, its weight, and its potential security risk. Officers may also ask you to power up electronic devices for inspection, demonstrating their authority in ensuring safe air travel.
In conclusion, while canned goods are typically allowed in checked bags, the final say rests with the TSA officer at the checkpoint. To ensure a smooth travel experience, it is advisable to familiarise yourself with the TSA guidelines and be prepared for additional screening or alternative arrangements, such as shipping your items to your destination.

Screening rules vary by country
Screening rules do vary by country, so it's always best to check the regulations for your destination country. For example, if you are entering the United States from another country, you will have to go through customs, where your bag might be screened, and the rules and regulations about what you can and cannot bring into the U.S. differ from what TSA allows.
In the U.S., the Transportation Security Administration (TSA) has stringent rules for liquids, which include liquid foods such as yoghurt or gravy. Liquids are not permitted in carry-on luggage if they are in containers larger than 3.4 ounces. However, frozen liquids are allowed through the checkpoint as long as they are frozen solid. Solid foods are usually permitted in carry-ons, and fresh fruits and vegetables are allowed in checked bags.
In some cases, it is the TSA agent in your security line who makes the call about a particular item. For example, some people have reported taking pizza through security, while others have had burritos confiscated. It is also worth noting that even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns.
