Many businesses use First-Class Mail, Priority Mail, or Standard Mail for regular mailings and Priority Mail Express for important business documents, like contracts and sales orders.
Priority Mail Express prices are based on the weight of the piece, and how far the piece travels except when USPS-provided Priority Mail Express Flat Rate packaging is being used.
Priority Mail Express Flat Rate packaging: Use for anything mailed in the special Flat Rate Envelopes or Boxes provided by the USPS, regardless of weight or domestic destination (70 pound weight limit).
Lower commercial prices are available for Priority Mail Express items that meet eligibility standards and must contain an Intelligent Mail barcode or you could be charged a non-compliance fee.
--When using USPS-provided packaging, you will be charged for the class of mail printed on the packaging.
