How many days does a sender wait before initiating tracer actions for material sent outside the continental United States?

The sender is required to wait 45 days before initiating tracer actions for material sent outside the continental United States. This 45-day timeframe is established to allow sufficient time for international mail and packages to reach their destination, considering various factors such as distance, customs processing, and potential delays due to logistical issues. If the material has not arrived within this period, it is reasonable to assume that there may be an issue with the delivery, prompting the need for tracer actions to locate the missing item. This waiting period is a standard practice in postal and logistics operations to balance thoroughness while avoiding premature investigative actions.
