For what weight does a parcel lose its mailable status?

A parcel loses its mailable status when it exceeds a weight of over 70 pounds. This weight limit is set to ensure that packages can be safely handled by postal employees and that they comply with transportation regulations. When a parcel exceeds this threshold, it typically requires special handling or shipping arrangements, which make it impractical for standard mailing procedures. Therefore, anything weighing more than 70 pounds is classified as non-mailable and cannot be sent through the regular postal services. Understanding this weight limit is essential for individuals preparing parcels for shipment, as it helps avoid delays and ensures compliance with postal regulations.
