What service provides preferential handling in dispatch but not in delivery, often used for live animals?

The service that provides preferential handling in dispatch but does not necessarily guarantee expedited delivery is Special Handling. This service is specifically designed to ensure that certain items, such as live animals, are treated with care during the shipping process. Special Handling emphasizes the careful handling and processing of the package throughout its journey, particularly during the dispatch phase, where the items are prepared for shipment and entered into the postal system.

In contrast, while services like Express Service and Priority Service may focus on quicker delivery times, they do not focus specifically on the handling of sensitive items during dispatch. Live Animal Shipping is a specific category of service that includes special provisions for shipping live animals but may not encompass the broader preferences and care that the Special Handling service provides. Therefore, Special Handling is the appropriate choice when considering preferential treatment during the dispatch process.
