How do I avoid potential fees and surcharges?

Fees and surcharges may apply to Priority Mail, Priority Mail Express, and Ground Advantage shipments based on the package volume and dimensions.

Dimensional weight, also called DIM weight or volumetric weight, is a pricing method that uses an estimated weight calculated from the length, width, and height of a package divided by a specific divisor determined by the carrier. For certain carriers, like USPS, UPS, and FedEx, a shipment's billable shipping cost is calculated based on dimensional weight if that value is higher than the actual weight.

To ensure you are receiving accurate shipping quotes, we recommend that you always include a package's total weight and package dimensions.

Flat Rate packages are not affected.

If dimensions are not provided or if dimensions are inaccurate: A $1.50 fee will be added for packages that are greater than one cubic foot in volume or have a box length greater than 22 inches.

Enter Dimensions to Avoid Surcharges

When preparing a package for shipment, if the dimensions section is present, be sure to enter the size of your package to ensure an accurate rate and avoid post-shipping adjustments.

If packages have dimensions that exceed machinable sorting requirements, nonstandard sizing fees will apply as follows:
