Frequently Asked Questions

What is a TSA customs lock?

A TSA customs lock refers to a lock that allows U.S. Transportation Security Administration (TSA) agents to open and inspect luggage without damaging the lock. These locks have a universal master key access system recognized by TSA officials at U.S. airports.

Are Hongji TSA locks accepted worldwide?

Yes, our TSA-approved locks are primarily designed for use in the United States, but many international airports and airlines also recognize and use TSA master keys for baggage inspection.

What are the design structures of password locks?

A code lock uses a series of numbers or symbols to open. Our combination locks feature precision-machined dials, anti-tamper mechanisms, and durable internal components to ensure long-term reliability and security.

Can I customize the color or logo on the padlocks?

Yes, we offer OEM and ODM services. You can customize the color, size, packaging, and add your logo through laser engraving, stamping, or printing. Contact us for bulk order details.
