Rolls or tubes measuring 26 inches or less fall into which category?

Items such as rolls or tubes measuring 26 inches or less are categorized as Irregular Parcel. This classification is important because it encompasses items that do not conform to traditional parcel shapes, such as rectangular boxes. Irregular Parcels are typically not uniform in size and can be more challenging to handle and process. They may also carry different rate structures and service options compared to other categories like Standard Mail, which usually applies to flat and rectangular mail pieces, or Flat Rate, which specifically refers to parcels that can be sent for a fixed rate regardless of weight or distance. Understanding these distinctions ensures that postal workers can properly categorize and process items based on their dimensions and shapes, facilitating effective delivery.
