What is the minimum weight for machinable parcel dimensions?

The minimum weight for machinable parcel dimensions is 6 oz because this weight is set to ensure that parcels can be efficiently processed by automated sorting equipment. Machinable parcels are those that fit specific size and weight criteria, allowing them to be handled by machines that streamline shipping and mail processing. This weight threshold enables the postal system to categorize and manage parcels effectively, ensuring they meet the necessary operational criteria for automated handling.

Parcels weighing less than 6 oz may not be processed in the same manner and could require different handling procedures or services, which do not align with the machinable classification. This classification helps simplify logistics for postal services by making sure the items processed are suitable for the machines used in sorting and distribution.
