Many travelers feel confused about the rules for carrying liquids in their hand luggage. At airport security, non-compliant toiletries may be confiscated and can delay your trip. A TSA-approved toiletry bag is designed to solve this problem. It is a transparent, resealable bag with a 1-quart (about 1-liter) capacity, made for holding liquids, gels, and aerosols that meet the 3-1-1 rule. This allows security officers to check your items quickly and let you pass without delay. Knowing its size limits, material options, and how to use it will help you clear security smoothly and avoid trouble.
To use a TSA-approved toiletry bag effectively, you first need to understand the 3-1-1 rule. This rule sets clear limits on the volume, quantity, and packing method for liquids in carry-on bags, and it is the key to knowing if your toiletry bag meets the requirements.
The TSA 3-1-1 rule is a security standard for liquids, gels, and aerosols in carry-on luggage. Each container must be no larger than 3.4 ounces (100 milliliters). All containers must fit in a single transparent, resealable bag with a capacity of no more than 1 quart (about 0.95 liters). Each passenger is allowed only one such bag. This rule applies to common liquid toiletries, cosmetics, skincare products, and small sprays. It helps security officers check items quickly and reduce delays at checkpoints.
Some items are exceptions, such as baby food, breast milk, and prescription medicines, but you must declare them at security and they may require extra screening.
Bringing containers larger than 100 milliliters, even if they are not full
Using opaque or semi-transparent bags that prevent visual inspection
Carrying more than one quart-size bag per person

| Size (inches) | Size (centimeters) | Notes |
|---|---|---|
| 7 × 8 in | 18 × 20 cm | Common retail size, widely accepted |
| 6 × 9 in | 15 × 23 cm | Longer design, still close to 1 quart |
| 7 × 5 × 2 in | 17.5 × 12.7 × 5 cm | Gusseted bottom; ensure total capacity stays within the limit |
Toiletry bags with a gusseted bottom look more structured, but if the base is too wide, security officers may consider them to exceed the 1-quart limit. It’s best to choose a bag with a slim gusset and clearly stated dimensions to avoid disputes.
Before your trip, compare your toiletry bag to a standard 1-quart food storage bag to ensure similar volume. This helps improve your chances of passing security checks smoothly.
While TSA-approved toiletry bags may look similar in shape and size, the material can greatly affect their transparency, durability, and overall user experience.
TPU
Offers higher clarity than PVC, with a clear surface that resists yellowing. Flexible, low-temperature resistant, and unlikely to crease or crack during frequent travel. Common in mid-to-high-end travel brands.
PVC
Affordable, highly transparent, easy to clean, and structurally stable—ideal for daily or frequent use. However, it may slightly yellow over time.
EVA
Lightweight, mildew- and moisture-resistant. Often used in budget giveaways or for occasional travel. Less transparent and less premium in feel compared to TPU/PVC, and may become cloudy or crack with extended use.
Ziploc PE
Inexpensive and compliant in capacity, but not durable. Best for temporary use or infrequent flyers.
Tip: If you travel often, choose TPU for its superior clarity, durability, and overall quality.
| Material | Transparency | Durability | Flexibility | Weather Resistance | Cost Level | Ideal Users & Scenarios |
|---|---|---|---|---|---|---|
| TPU | ★★★★★ | ★★★★★ | ★★★★★ | Low-temp resistant, resists yellowing | Mid-High | Frequent travelers seeking quality and longevity |
| PVC | ★★★★☆ | ★★★★☆ | ★★★★☆ | Slightly less durable than TPU | Mid | Daily or frequent use, mid-range budget |
| EVA | ★★★☆☆ | ★★☆☆☆ | ★★★☆☆ | Mildew/moisture resistant but prone to clouding | Low | Occasional travel, budget giveaways |
| Ziploc PE | ★★★☆☆ | ★☆☆☆☆ | ★★☆☆☆ | Intended for one-time use | Very Low | Temporary TSA checks, rare flyers |
Choosing a TSA-approved toiletry bag ensures a smoother airport experience and helps keep your travels organized and efficient.
Faster Security Screening
Transparent, compliant design allows security officers to quickly see the contents, reducing the need for manual checks and cutting down on wait time.
Better Organization
Keeps liquids, gels, and travel essentials in one place, preventing leaks from spreading to other belongings and making it easier to find what you need on the go.
Compliance Peace of Mind
Adheres to TSA’s 3-1-1 rule, avoiding confiscation due to oversized containers or noncompliant bags, and reducing unnecessary travel hassles.
Travel Versatility
Beyond airport security, compliant toiletry bags are also useful for train and bus travel, gym visits, business trips, and everyday use.
Use Travel Bottles Under 100ml
Opt for screw-cap or leak-proof pump designs to minimize the risk of spills.
Group by Category
Separate skincare, haircare, and makeup items for easier access and organization.
Leak Prevention
Wrap bottle openings with plastic wrap before tightening the caps, then reinforce with tape.
Easy Access at Security
Place the toiletry bag at the top of your carry-on so you can remove it quickly during screening.
Permitted Items
Liquids or semi-liquids under 100ml per container, such as shampoo, lotion, toothpaste, perfume, and spray bottles.
Prohibited Items
Any liquid in a container over 100ml, as well as certain liquid or paste-like foods (e.g., peanut butter, yogurt).
Solid Alternatives
Shampoo bars, toothpaste tablets, solid perfumes, and makeup remover wipes, which are not subject to liquid restrictions.

TSA-Approved Toiletry Bag: Best for U.S. and most international flights. Helps you clear security quickly and avoid having items confiscated.
Regular Toiletry Bag: Suitable for checked luggage or land travel when TSA liquid rules do not apply.
EU/UK: Each liquid container must be ≤100ml (3.4oz). All liquids must fit into a single resealable transparent bag with a total capacity ≤1L. The bag must close fully and be screened separately.
Canada, Japan, Singapore: Rules are generally the same as TSA (3.4oz / 100ml per container, total 1L). Some airports provide compliant bags free of charge before screening.
Australia & New Zealand: Follow the same international standard, but certain liquid medicines and baby items require separate declaration.
Pro Tip: Pack according to the strictest rules so you can pass security smoothly even during layovers, and avoid having to discard liquids.
TSA-approved clear toiletry bags are often exposed to liquids, cosmetics, and humidity during travel. Without regular cleaning, their appearance and lifespan may be affected. Transparent PVC or TPU may scratch, yellow, or retain water spots. Damaged zippers or seals can also slow down security checks and reduce leak protection.
Daily Cleaning
After each trip, wipe the bag gently with warm water and mild soap, especially areas with liquid residue. Avoid alcohol-based or strong acidic/alkaline cleaners to prevent material damage. Let the bag air-dry in a cool, ventilated place—do not expose to sunlight or use a hairdryer.
Proper Storage and Care
When not in use, store the bag in a dry, shaded place. Keep it away from sharp objects to prevent scratches. Avoid prolonged pressure or folding, which may cause deformation or loosen seals. Before traveling, check zippers or closures to ensure smooth use at security.
Extra Tip
If cosmetics, lotion, or sprays spill inside the bag, wipe them off immediately to prevent staining or odors. TPU resists yellowing better than PVC, but both materials still need regular cleaning to stay clear.
TSA-approved toiletry bags are not only essential for passing security checks, but they also help save time and reduce unnecessary hassle during travel. Compared to regular toiletry bags, they follow stricter standards for size, transparency, and closure type to ensure compliance with the TSA 3-1-1 liquid rule. When choosing one, consider your travel frequency, material durability, and personal habits. Opt for designs with high transparency, sturdy structure, and easy-to-clean surfaces to ensure smooth security clearance while keeping your items neat and organized throughout the trip.
