US Customs Regulations for Flying with Cash

When you enter or leave the US , you must declare cash or monetary instruments worth more than $10,000 . This is part of America's effort to prevent money laundering, terrorist financing, and other illegal activities .   

The rule applies to:

• US dollars and foreign currency equivalents
• Traveler's checks
• Money orders, cashier's checks, and promissory notes
• Bearer bonds and negotiable instruments
• Precious metals and rare coins (considered cash for customs)

Important:  The $10,000 limit applies to the total carried by a group , not per person. For example, a family of four each carrying $3,000 (total $12,000) must declare the amount. 

Cash Limits in Other Countries

Different countries have their own cash declaration rules : 

• United Kingdom:  Declare £10,000 or more when entering/leaving.
• European Union:  Declare €10,000 or more.
• Canada:  Declare amounts over CAD 10,000.
• Australia:  Declare more than AUD 10,000 using a CBM-PC form.
