Shipping: How does a shipper (USPS, UPS, FedEx) detect if illegal items (narcotics, explosives, etc.) are being mailed?
Interesting. So, what happens if someone tries to mail illegal items?
If an illegal item is detected, the package is usually seized by law enforcement authorities, and the sender can face criminal charges. The shipping company may also refuse future business from the sender.
