If FCM weighting over 13 ounces is sent, what class is it categorized as?

When a piece of First-Class Mail (FCM) weighs over 13 ounces, it is categorized as Priority Mail. This classification occurs because, according to postal regulations, the weight limit for First-Class Mail is 13 ounces. Once the weight exceeds this limit, the item cannot continue to be processed under First-Class Mail standards and instead falls into the Priority Mail category.

Priority Mail offers a range of benefits, including faster delivery times compared to other classes, typically within 1-3 business days, as well as tracking services and flat rate shipping options. This distinction is crucial for postal operations, as it ensures that customers receive appropriate service levels based on the weight and urgency of their items.

In contrast, First-Class Mail below 13 ounces serves everyday mailing needs, while categories like Standard Mail and Express Mail serve different purposes, focusing on bulk mail and expedited shipping, respectively.
