✈️ Quick Answer: For ordinary petroleum jelly, plan around TSA’s gel/paste liquids rule: a container up to 3.4oz (100ml) in your quart bag. Medically necessary products have a separate screening exception; declare them rather than treating every larger jar as prohibited.
Is Vaseline a Liquid?
Carry-On Luggage
✅ Allowed: Use the standard liquids allowance for an ordinary petroleum-jelly toiletry. Declare medically necessary quantities separately.
Checked Luggage
✅ Allowed: The carry-on 3-1-1 rule does not apply in checked baggage. Confirm any restrictions for a medicated or unusual formulation.
What You Need to Know
This advice applies the general gel/paste rule to ordinary petroleum jelly; it is not a TSA approval of a particular brand or medicated product.
Choose a small, clearly labeled container and keep the lid secure. A separate pouch helps prevent greasy residue spreading through the rest of your wash kit.
For medical needs, TSA allows reasonable trip quantities of medically necessary liquids beyond the ordinary allowance, subject to declaration and screening. Check the exact product and route with TSA and relevant authorities.
Smart Packing Tips
- ✅ Pack a small container for ordinary toiletry use.
- ✅ Keep medical products identifiable and accessible for separate screening.
- ✅ Check destination rules separately if your product contains medication.
💡 Pro Tip: Ordinary carry-on liquids, gels and pastes use containers up to 3.4oz (100ml) in one quart-sized bag. Medical and infant-related exceptions have separate screening procedures. See our TSA quart size bag guide to pack liquids right.
