What classification applies to a parcel that weighs more than 70 pounds?

A parcel that weighs more than 70 pounds falls under the classification of nonmailable. This is because the United States Postal Service (USPS) has specific weight limits for various mailing options, and any parcel exceeding 70 pounds cannot be mailed through standard services. Nonmailable items are those that do not comply with USPS regulations for mailing, which include restrictions based on weight, size, or content.

In contrast, options like Priority Express Mail and USPS Retail Ground apply to different categories and weight limits that do not exceed this threshold, while nonmachinable refers to items that cannot be processed by automated systems but can still be mailed if they meet other criteria. Thus, classifying a parcel over 70 pounds as nonmailable correctly reflects mailing policies established by the USPS.
