Navigating airline security with aerosol products can be confusing. As a leading aerosol can manufacturer with decades of experience, we clarify the latest regulations (2024-2025) based on direct testing and international safety standards. This guide will help you travel safely and avoid confiscations at security checks.
Let’s cut through the noise. The rules for traveling with aerosol cans hinge on their classification and placement. The table below summarizes the key 2025 requirements for personal travel:
Travel Type | Aerosol Type | Volume/Pressure Limits | Key Requirements |
Carry-On Luggage | Non-flammable (e.g., personal care) | 3.4 oz (100 ml) or less per container | Must fit within a single quart-sized, clear plastic bag (3-1-1 rule). |
Checked Baggage | Non-flammable (UN 2P) | Under 18 oz (500 g) per can; total net quantity ≤ 2 kg (4.4 lbs) per person | Must be securely packed to prevent accidental release. Flammable aerosols are prohibited. |
But here’s a critical update for brands: the IATA’s latest guidelines now allow higher pressure limits (up to 300 kPa) for cans using sustainable propellants like HFO-1234ze. This change reflects the industry's effort to balance safety with environmental progress.
Why Aerosol Cans Are Restricted—A Technical Perspective
As an engineer, I often explain that the risks boil down to pressure and flammability. At 30,000 feet, cargo hold temperatures can swing from -40°C to 50°C. Standard cans with hydrocarbon propellants (e.g., butane) may rupture or leak under these conditions. In 2023, the FAA documented 58 incidents involving aerosol-related pressure incidents.
Packing Tips from a Pro: Avoid These Common Mistakes
The biggest error? Assuming "non-flammable" means "risk-free." Even water-based aerosols can explode if damaged. Always:
1. Cap the nozzle with a protective cover (we include them with every AeroGuard can).
2. Wrap cans in a zip-lock bag to contain leaks.
3. Declare contents if shipping commercially—using UN1950 labels is mandatory.
Pro tip: Our clients who use custom-printed cans with clear hazard symbols report fewer delays at security checks.
