What type of shipping papers are private carriers allowed to use for multiple shipments?

Private carriers are allowed to use permanent papers for multiple shipments because these documents are designed to be long-lasting and can accommodate the needs of various shipments over time. Permanent shipping papers contain all necessary information pertaining to the shipment, such as the type of cargo, its quantity, and handling instructions, which can be reused and referenced repeatedly for different shipments.

This efficiency is particularly useful in logistics and shipping operations, as it minimizes paperwork and administrative overhead. Instead of creating new documents for each individual shipment, carriers can utilize these standardized permanent papers, ensuring that all information remains consistent and easily accessible across multiple shipments.

The other options typically refer to documents that either serve a specific, temporary purpose, or are not suitable for the sort of repeatable usage required for ongoing shipping operations.
