Rolls and tubes exceeding 26 inches in length are categorized as which type of mailpiece?

Rolls and tubes exceeding 26 inches in length are categorized as non-machinable parcels primarily because they do not conform to the standard dimensions and characteristics required for automated processing by postal services. Non-machinable parcels often require manual handling, which includes items that are awkwardly shaped or are too long or bulky for standard sorting machines.

This categorization is essential for mailing and shipping because it affects the pricing and handling of the parcels. Non-machinable parcels may incur higher postage costs due to the additional handling required and the need for special processing. Understanding these classifications helps businesses and individuals choose the correct mailing options for their needs and ensures that they comply with postal regulations.
