Butter is a common spreadable and flavorful ingredient, and if you are planning to bring any type of butter on your next flight, here is the short answer.
You can bring butter on a plane in both carry-on and checked baggage, but in carry-on soft butter needs to follow the TSA 3-1-1 liquid rule of 3.4 oz / 100 ml (96 grams). You can take larger quantities of butter in checked baggage.
In this post I will cover everything you need to know about taking butter in carry-on and checked bags in both domestic and international flights.
Let’s dive right in.
TL;DR
- You can bring butter on a plane in both carry-on and checked baggage.
- Soft or spreadable butter in your carry-on need to follow the TSA 3-1-1 rule and be 3.4 oz / 100 ml / 96 g or less per container.
- Frozen butter can exceed the 3.4 oz / 100ml limit if it is completely solid at the time of secreting.
- There are no TSA limits on the amount of butter you can pack in checked baggage.
- Freeze butter and pack it in an insulated bag or cooler if you’re checking it to help keep it cold.
- For international flights, the same TSA Rules applies, but entering butter and other dairy products to another country may have different rules.
Can You Take Butter Through The TSA In Domestic Flights?
The Transportation Security Administration (TSA) has strict rules regarding liquids, gels, creams, and spreadable items.
These items are allowed, but only in limited quantities.
Even though they don’t specifically mention butter on their website, butter falls into the creamy and spreadable category, just like peanut butter and some types of cheese.
I also checked the TSA social media mainly X to find some answers.
Eve wanted to take an 8 oz / 227 grams block of butter in her carry-on.
The TSA folks replied that creamy and spreadable items, such as butter, must stay within the TSA 3.4 oz / 100 ml liquid rule.
Each piece of butter must be 3.4 oz / 100 ml (96 grams) or less and placed in a quart-sized bag, which is not practical for butter and most food.
You can always take frozen butter or buy it after you pass the security checkpoint instead.
Frozen butter is allowed in quantities greater than 3.4 oz / 100 ml, but it needs to be completely solid when you go through the security checkpoint.
| Butter | Carry-on Baggage | Checked Baggage |
|---|---|---|
| Pear butter | 3.4 oz / 100 ml for each container | No limits |
| Margarine | 3.4 oz / 100 ml containers | No limits |
| Apple Butter | 3.4 oz / 100 ml containers | No limits |
| Shea butter | 3.4 oz / 100 ml containers | No limits |
| Sunflower butter | 3.4 oz / 100 ml containers unless it is for medical use | No limits |
| Cocoa butter | 3.4 oz / 100 ml for each container | No limits |
Can You Take Butter In Checked Baggage?
There are no limits on the amount of butter you can bring checked bags.
If you want to take a big chunk of butter (for any reason) and you don’t want to split it into small pieces, then it is a good idea to place it in your checked bag, but you will need to do some preparation.
Freeze the butter and use a cooler to maintain its temperature during transportation. Just ensure that the cooler is well secured.
Consider using a small cooler that will fit within the checked baggage size limits so you don’t have to pay oversized luggage fees.
Can You Take Butter On International Flights?
If you are flying to a different country, it is important to know that the regulations for bringing butter and dairy products into foreign countries differ from one country to another.
While the TSA may allow you to bring butter on a plane, other countries may have different rules at their customs.
Please double-check the exact rules of your destination country.
Countries regulate the import of food items to help prevent the spread of pests and diseases.
Here are the rules for bringing butter to the US, the UK, and some other countries.
| USA | Butter are generally admissible |
| UK | You can not bring butter or diary products from countries outside the EU or Faroes Islands |
| Australia | Allowed for personal use but you need to declare it |
| Canada | Allowed |
| New Zealand | Allowed for personal use but you need to declare even small amounts |
Final Thoughts
It is admissible to bring butter on planes, but if it is not frozen, it needs to follow the TSA 3-1-1 liquid rule of 3.4 oz / 100 ml / 96 grams for each individual piece.
If you are traveling with a big chunk of butter, consider taking it in a cooler as checked baggage.
For international travel, ensure that you are allowed to bring butter into your destination country.
I hope this helps.
Happy travels.
Frequently Asked Questions About Bringing Butter on a Plane
Can you bring butter in your carry-on if it’s inside a sandwich?
Butter that you already spread inside a sandwich or other solid food is generally allowed in your carry-on. The TSA liquid rule applies only to containers of butter, not butter inside food.
Why does the TSA consider butter a liquid?
The TSA treats soft and spreadable foods, including butter, as liquids or gels. That’s why soft butter in your carry-on must stay within the 3.4 oz / 100 ml limit.
Can you bring whipped or melted butter on a plane?
You can bring whipped or melted butter, but in your carry-on, each container must be 3.4 oz / 100 ml or smaller. You can pack larger amounts in checked baggage.
How should you pack butter for a flight?
Keep butter in its original packaging or place it in a leak-proof container. If you’re checking it, freeze it before your flight and pack it in an insulated bag or cooler to help it stay cold.
Can you bring French butter home from France?
In most cases. Freeze the butter before your flight, pack it in your checked baggage inside an insulated bag, and check your destination country’s customs rules before you travel.
Can you bring homemade butter on a plane?
Homemade butter follows the same rules if it’s soft, keep each container under 3.4 oz / 100 ml in your carry-on, or place larger quantities in checked baggage.
Can you bring butter through airport security?
You can take butter through airport security, but soft butter in your carry-on must follow the TSA 3.4 oz / 100 ml liquid limit. Frozen butter can exceed this limit if it is completely solid at screening.
Will butter melt during a flight?
If you’re traveling for several hours, freeze the butter before your trip and pack it in an insulated bag or cooler. This helps keep it cold and prevents a messy leak.
