What two surcharges can be applied to USPS Retail Ground?

The choice of oversized and dimensional weight as the correct surcharges that can be applied to USPS Retail Ground is accurate because these surcharges specifically relate to the characteristics and size of the packages being shipped.

Oversized refers to packages that exceed the maximum size limits set by USPS for regular retail ground service. When a package is larger than these dimensions, it incurs an additional charge to account for the handling and transportation complexities that larger packages impose.

Dimensional weight pricing is also a critical aspect for ground shipping. This pricing method uses the dimensions of a package to calculate shipping costs based on the space a package occupies in relation to its actual weight. If the dimensional weight exceeds the actual weight of the parcel, the dimensional weight applies, resulting in a higher shipping fee.

Both of these surcharges are designed to ensure that USPS can efficiently allocate resources and manage the logistics of shipping packages that take up more space, reflecting the increased costs associated with handling these items.
