As summer travel ramps up in 2025, the Transportation Security Administration (TSA) has rolled out updated regulations that ban several popular travel items from checked and carry-on luggage. These changes, driven by safety concerns like fire risks from lithium-ion batteries, aim to keep air travel secure but have caught many travelers off guard. From portable chargers to propane tanks, understanding what’s prohibited is crucial to avoid delays, confiscations, or hefty fines at airport security checkpoints. This comprehensive guide breaks down TSA’s 2025 banned items list, explains why these rules matter, and offers practical tips to ensure a smooth travel experience.
Why TSA Updated Its Regulations in 2025
The TSA’s latest restrictions focus heavily on items posing fire or explosion risks, particularly lithium-ion batteries, which have been linked to in-flight incidents. A notable example is the January 2025 fire on Air Busan Flight 391, where a power bank caused injuries to seven passengers. This incident, among others, prompted the TSA and Federal Aviation Administration (FAA) to tighten rules on battery-powered devices and flammable materials. Additionally, the enforcement of the REAL ID Act on May 7, 2025, has heightened overall security measures, making compliance with TSA guidelines more critical than ever.
These updates aren’t just about safety—they’re about streamlining the screening process as airports adopt advanced technologies like computed tomography (CT) scanners. While these scanners allow some exemptions (like larger quantities of certain liquids), they’ve also led to stricter enforcement of prohibited items to prevent in-flight emergencies. Let’s dive into the key items banned in 2025 and what travelers need to know.
TSA’s 2025 Banned Items List: What’s Off-Limits
1. Lithium-Ion Batteries and Power Banks
One of the most significant changes in 2025 is the ban on lithium-ion batteries, including portable chargers and power banks, in checked luggage. These devices must now be packed in carry-on bags with their terminals protected to prevent short-circuiting. The TSA cites the risk of overheating, which can lead to fires in the cargo hold where they’re harder to control. Airlines like United have long enforced similar rules, but the TSA’s blanket prohibition across all U.S. flights marks a stricter stance.
Travel Tip: Pack your phone chargers, laptop batteries, and e-cigarettes in your carry-on. Ensure devices are powered off and stored securely. You’re allowed two spare batteries (101–160 Wh) in carry-ons with airline approval, but batteries for commercial use are prohibited.
2. Propane Tanks
Propane tanks, even small ones used for camping, are now banned from both carry-on and checked luggage. This rule gained attention after a passenger at Pensacola International Airport attempted to bring a propane tank in their carry-on, prompting a TSA warning. Camp stoves are permitted only if they’re completely empty and free of fuel residue, subject to airline approval.
Travel Tip: If you’re planning a camping trip, purchase propane at your destination or ship it separately via ground transport, as air transport is strictly prohibited.
3. High-Proof Alcohol (Over 140 Proof)
High-proof alcohol, such as grain alcohol or strong rums exceeding 70% alcohol by volume, is banned from both carry-on and checked luggage due to its flammability. Mini bottles under 3.4 ounces are allowed in carry-ons if they comply with the TSA’s 3-1-1 liquids rule (3.4 ounces or less, in a clear, quart-sized bag).
Travel Tip: Stick to travel-sized alcohol bottles for souvenirs and ensure they’re securely packed in your carry-on. Check the alcohol percentage before packing to avoid confiscation.

4. Smart Luggage with Non-Removable Batteries
Smart luggage with built-in lithium-ion batteries is banned unless the batteries are removable. Non-removable battery suitcases are prohibited in both carry-on and checked luggage due to fire risks. If your smart luggage has a removable battery, take it out and carry it in your carry-on bag.
Travel Tip: Before buying smart luggage, confirm the battery is detachable. Store the battery in your carry-on and double-check airline policies, as some may have additional restrictions.
5. Specific Aerosols
Aerosols like spray paint, bear spray, or other flammable sprays are banned from checked luggage due to the risk of explosion or fire during flights. Non-flammable aerosols, like certain personal care products, may be allowed in limited quantities in carry-ons, adhering to the 3-1-1 rule.
Travel Tip: Opt for travel-sized, non-flammable aerosols for toiletries. If you need bear spray for outdoor adventures, purchase it at your destination.
6. Weapons and Imitation Firearms
The TSA maintains strict rules on weapons, including firearms, knives, pepper spray, and stun guns, which must be declared and packed in checked luggage. Imitation firearms, such as toy guns, are banned from carry-ons entirely. In 2024, TSA officers confiscated 6,678 firearms at checkpoints, highlighting the importance of proper packing.
Travel Tip: Declare firearms at check-in and pack them in a locked, hard-sided case. Leave toy weapons at home to avoid delays.
7. Wrapped Gifts
While not banned, wrapped gifts are subject to unwrapping during screening, which can slow you down at checkpoints. The TSA recommends leaving gifts unwrapped until you reach your destination to avoid complications.
Travel Tip: Use gift bags or wrap presents after arriving to save time and prevent damage to wrapping during inspections.
New Exemptions: What’s Now Allowed
On a positive note, the TSA has relaxed restrictions on certain items thanks to advanced CT scanners at major airports. As of 2025, 11 items are exempt from the 3-1-1 liquids rule, allowing larger quantities in carry-ons. These include:
- Over-the-counter medications
- Breast milk and baby formula
- Ice packs for medical or food purposes
- Duty-free purchases (in sealed bags with visible receipts)
- Certain biological samples in spill-proof containers
Travel Tip: Notify TSA officers at checkpoints about exempt items for faster screening. Arrive early, as not all airports have CT scanners yet, and manual inspections may still apply.
How to Navigate TSA’s 2025 Rules
1. Check the TSA’s “What Can I Bring?” Tool
Before packing, visit the TSA’s official “What Can I Bring?” page to verify restrictions. This tool provides detailed guidance on thousands of items, from electronics to food. You can also text AskTSA at 275-872 for real-time assistance.
2. Understand the REAL ID Requirement
Starting May 7, 2025, a REAL ID-compliant driver’s license or other federal ID (like a passport) is required for domestic flights. Non-compliant IDs may lead to enhanced screening or denied boarding.
Travel Tip: Check your ID’s REAL ID status (look for a star symbol) well before your trip. Apply for a REAL ID at your state’s DMV if needed.
3. Pack Smart to Avoid Fines
TSA fines for prohibited items can reach $17,062 per violation. In 2024, thousands of items, including firearms and propane tanks, were confiscated, often due to traveler ignorance. Double-check your bags to avoid costly mistakes.
Travel Tip: Use a packing checklist and review TSA guidelines for each item. If unsure, contact your airline or the TSA directly.
4. Arrive Early
With new regulations and REAL ID enforcement, expect longer security lines, especially during peak summer travel. Arriving 2–3 hours early for domestic flights and 3–4 hours for international flights gives you buffer time for screenings.
5. Stay Informed
Rules can change, so follow the TSA’s social media (@TSA on X) for real-time updates. Recent posts have emphasized checking carry-on restrictions and declaring self-defense items properly.
Why These Changes Matter
The TSA’s 2025 updates reflect a balance between safety and convenience. Lithium-ion battery fires, like the Air Busan incident, underscore the need for strict rules, as cargo hold fires are harder to manage than cabin incidents. Meanwhile, exemptions for items like medications show the TSA’s effort to adapt to traveler needs using advanced technology. By understanding and following these rules, you can avoid delays, protect your belongings, and contribute to safer skies.
