Does Vaseline Count as a Liquid for Flying?
When it comes to air travel, understanding what qualifies as a liquid can be quite confusing. The Transportation Security Administration (TSA) has specific guidelines regarding liquids in carry-on luggage, and Vaseline, a popular petroleum jelly, often raises questions. Let's delve into the topic to provide a clear understanding.
Understanding the TSA's 3-1-1 Rule
To simplify the process, the TSA has implemented the 3-1-1 rule for liquids in carry-on luggage. This rule states that each passenger is allowed to carry:
- 3.4 ounces (100 milliliters) or less of liquids, gels, and aerosols per container
- 1 quart-sized, clear, plastic, zip-top bag to hold these items
- 1 bag per passenger placed in a screening bin for X-ray examination
Why the 3-1-1 Rule?
The 3-1-1 rule was implemented in response to a liquid bomb plot in 2006. It aims to prevent passengers from carrying large quantities of liquids that could potentially be used to make explosives. However, it's essential to understand that the rule applies to liquids with a low viscosity, i.e., substances that can flow easily.

Vaseline: A Solid at Room Temperature
Vaseline, or petroleum jelly, is a semi-solid substance at room temperature. It has a high viscosity, meaning it doesn't flow easily. Instead, it maintains its shape and can be molded. Therefore, it doesn't fall under the TSA's definition of a liquid, gel, or aerosol.
Vaseline and the TSA's Prohibited Items List
While Vaseline isn't considered a liquid, it's crucial to note that it's not explicitly mentioned in the TSA's prohibited items list. However, it's important to remember that the TSA has the right to deny any item that they deem a security risk, regardless of whether it's on the prohibited list.
Can Vaseline Be Packed in Checked Luggage?
If you're unsure about carrying Vaseline in your carry-on, you can always pack it in your checked luggage. The TSA doesn't have restrictions on liquids in checked bags, as long as they're within the airline's weight and size limits.

What If a TSA Officer Says Vaseline Is a Liquid?
If a TSA officer insists that Vaseline is a liquid and you disagree, politely ask to speak with a supervisor. You can also ask to have the Vaseline tested using the TSA's liquid explosives detector. If the test comes back negative, the Vaseline should be allowed in your carry-on.
Alternatives to Vaseline for Air Travel
If you're concerned about carrying Vaseline in your carry-on, consider using an alternative product that's specifically designed for travel. These products often come in small, TSA-approved sizes and can be easily packed in your carry-on.
| Product | Size |
|---|---|
| Travel-sized lip balm | 0.25 ounces (7 grams) |
| Travel-sized hand cream | 1 ounce (28 grams) |
| Travel-sized face moisturizer | 1.7 ounces (50 grams) |
Remember, these alternatives should still fit within the TSA's 3-1-1 rule. Always check the TSA's website or contact them directly if you're unsure about a specific product.
