TSA Bag Screening Items (Airport Packing Checklist)

For a smoother screening process, sort your belongings before you pack: keep compliant liquids together, place spare lithium batteries and power banks in your carry-on, and put items allowed only in checked baggage there. Check TSA guidance, FAA battery rules, airline limits, and destination requirements. Rules can differ by item, route, and carrier, so verify them before departure.

Frequent travel can make packing feel like a test with rules that are hard to see until you reach the checkpoint. A little planning helps, but it cannot guarantee that a bag will avoid extra screening. TSA officers may need to inspect an item, and an airline or destination may set rules beyond TSA screening guidance.

I use a simple approach: check the route, sort items by bag, pack them so they are easy to inspect, then verify the rules again before leaving. The guide below covers common items and the limits most likely to affect a travel bag. Treat it as a planning checklist, not a replacement for current official guidance.

Plan around TSA, FAA, airline, and destination rules

TSA screening rules cover what may pass through a U.S. checkpoint. FAA rules govern dangerous goods on aircraft, including many batteries. Airlines set baggage and approval procedures, while destination countries may apply their own restrictions. Check all four when an item is unusual, regulated, or essential to your trip.

Check your route and bags before packing

Start with the operating airline, which may differ from the company that sold your ticket. Confirm your carry-on and checked-bag allowance, any weight or size limits, and special-item procedures. There is no single carry-on size or weight limit that applies to every airline and route.

Then list items that may need special attention: medicines, batteries, powders, sports gear, sharp tools, or firearms. For international trips, check the rules for each country where you will clear security or customs. A connection can add requirements even when you do not plan to leave the airport.

Separate carry-on and checked items

Carry-on and checked bags have different screening and safety limits. Some items can go in either bag, while others must stay with you or be checked under specific conditions. Sorting items before packing reduces last-minute repacking and helps you spot a rule that needs confirmation.

Item	Carry-on	Checked bag	Packing note
Power bank or spare lithium battery	Yes	No	Protect terminals from contact
Device with installed battery	Usually practical	Sometimes, subject to rules	If checked, switch it fully off and protect it from damage or accidental activation
Liquids, gels, creams, and pastes	Limited by 3-1-1 guidance	Often suitable	Check special rules for medicines and other exceptions
Firearm	No	Only under required conditions	Unloaded, locked in a hard-sided case, and declared to the airline
Powder on a U.S.-bound international flight	May face extra screening above 12 oz (350 mL)	Often avoids that cabin screening issue	Screening may still apply to checked baggage

This table is a starting point, not a complete list of permitted or prohibited items. Use TSA’s “What Can I Bring?” lookup for an item-specific answer, and follow airline instructions for batteries, firearms, and other regulated goods.

Pack liquids, batteries, and special items correctly

Packing details matter because screening rules often depend on an item’s type, size, or condition. Keep items easy to identify and inspect. Do not hide, disguise, or mislabel anything restricted; if a rule is unclear, check before travel or leave the item out.

Liquids, gels, aerosols, creams, and pastes

For carry-on bags, TSA’s 3-1-1 guidance generally means each container must hold no more than 3.4 ounces (100 milliliters), and the containers must fit in one quart-size bag per passenger. The limit applies to the container’s capacity, not how much liquid remains inside it.

Put the bag where you can reach it if you are asked to remove it. Medically necessary liquids may qualify for an exception, but you should tell the TSA officer and expect additional screening. Check TSA’s current instructions for the item and route, especially if you are carrying medicine, infant supplies, or a large amount of liquid.

Lithium batteries and power banks

A power bank is a spare lithium battery, not just an electronic accessory. Spare lithium batteries and power banks belong in carry-on baggage, not checked baggage. Protect battery terminals from short circuits, such as by using the original packaging, a battery case, or another method that prevents contact with metal objects.

Batteries up to 100 watt-hours (Wh) are generally allowed in carry-on baggage. Batteries from 101 to 160 Wh require airline approval and are generally limited to two spare batteries per passenger. Larger batteries may be prohibited or need special authorization. Ask the airline before packing one; do not assume a device’s label or marketing name tells you its Wh rating.

Devices with installed batteries are best kept in carry-on baggage when practical. If you place one in checked baggage, switch it completely off, protect it from damage, and prevent accidental activation. Airline rules may be stricter, so check the carrier’s policy.

Powders, sharp items, and firearms

On international flights bound for the United States, powder substances over 12 ounces (350 milliliters) may receive additional screening. If screening cannot clear a powder in the cabin, it may not be allowed there. Packing it in checked baggage can avoid that cabin screening issue, but it does not guarantee acceptance under all airline or destination rules.

Check TSA’s item lookup for sharp objects and tools, since permission depends on the item and its features. For firearms, TSA requires checked baggage only: the firearm must be unloaded, placed in a locked hard-sided container, and declared to the airline at check-in. Confirm the airline’s process and the laws that apply at your destination.

Two practical packing examples

These examples show how to apply the checks; they are not reports of specific travelers or guarantees of a screening outcome.

• A commuter with a laptop and power bank: Put the power bank in the carry-on and protect its terminals. Keep the laptop accessible in case an officer asks to inspect it. Check the airline’s battery rules, especially if the power bank exceeds 100 Wh.
• A traveler with toiletries and a large powder container: Put carry-on liquids in compliant containers inside one quart-size bag. If the trip is international and bound for the United States, consider placing a powder over 12 ounces (350 milliliters) in checked baggage, then verify airline and destination rules.

Verify the final bag against current screening guidance

A final check catches common packing mistakes, but it cannot predict every inspection. Screening officers may ask to examine a bag or remove an item. Pack so you can respond without unpacking everything, and follow instructions at the checkpoint.

Use this sequence before departure:

• Survey: Confirm route, operating airlines, baggage allowance, destination restrictions, and any medical, battery, sporting, or regulated items.
• Sort: Separate carry-on, checked, and prohibited items. Check TSA guidance and FAA battery rules for each item that raises a question.
• Pack: Group compliant liquids together. Keep spare batteries in your carry-on with protected terminals. Secure fragile or sharp permitted items.
• Verify: Recheck TSA’s “What Can I Bring?” lookup, airline limits, and connection-country rules. Be ready to remove items for inspection.

For example, finding a power bank in a checked suitcase during this check is a clear reason to move it to your carry-on and protect its terminals. Do not rely on an assumption that screening will catch or correct a packing error.

Frequently asked questions

These answers cover common packing questions, but item-specific decisions can depend on current rules, battery capacity, route, and airline policy. When a rule affects an essential or high-value item, verify it with the relevant authority or carrier before travel.

Can I pack a power bank in checked luggage?
No. Spare lithium batteries and power banks must go in carry-on baggage. Protect their terminals to prevent short circuits.

How many liquids can I bring in my carry-on?
Each container must generally be 3.4 ounces (100 milliliters) or less, and all containers must fit in one quart-size bag per passenger.

Does the 3.4-ounce limit apply to the amount left in a bottle?
The rule concerns the container’s capacity. A larger container is not made compliant by carrying only a small amount inside.

Can I bring prescription liquid medicine through screening?
Medically necessary liquids may qualify for an exception. Tell the TSA officer and check current TSA instructions for your medicine and route.

Can a device with a lithium battery go in checked baggage?
Sometimes, subject to applicable rules. If checked, it must be completely switched off and protected from damage or accidental activation. Carry-on is preferable when practical.

What is the battery limit for a power bank?
Up to 100 Wh is generally permitted. A battery from 101 to 160 Wh requires airline approval and is generally limited to two spare batteries per passenger. Ask the airline about larger batteries.

Can I take a powder container over 12 ounces in the cabin?
On an international flight bound for the United States, it may receive extra screening and could be refused in the cabin if screening cannot clear it. Checked baggage may avoid that cabin screening issue.

Can I pack a firearm in my carry-on?
No. TSA requires firearms to be transported in checked baggage, unloaded, in a locked hard-sided container, and declared to the airline.

Does TSA set one carry-on size limit for every airline?
No. Carry-on size and weight limits can differ by airline and route. Check the operating carrier’s baggage policy.

Can a bag pass screening if it follows this checklist?
No checklist can guarantee that. Officers may inspect a bag or ask you to remove an item. Follow their instructions and verify current rules before travel.
