At what point do company mail screenings occur?

Company mail screenings occur before acceptance for carriage because this is the critical phase where all mail and packages are evaluated for security risks prior to being transported. This process is essential to ensure that any potentially dangerous or prohibited items are identified and mitigated before they are placed on an aircraft. By conducting screenings at this stage, companies can comply with security regulations and protect the safety of their operations, personnel, and passengers.

Screening mail after a flight has departed, at the destination airport, or during passenger security checks would not effectively address potential security threats before the items are already in transit, making the time of acceptance for carriage the most logical and necessary point for screenings.
