USPS Non-Standard Package and Non-Compliance Fees

Mail Classes

USPS has non-standard package fees and non-compliance fees for packages that exceed certain lengths for the following Mail Classes:

  • Priority Mail Express

  • Priority Mail

  • Ground Advantage

Non-Standard Package Fee calculation

Note that fees are additive. If a package is greater than 22" in length and greater than 2 cubic feet, both length and volume fees may be applied.

Length Fee

USPS Priority & Priority Mail Express

  • Parcels that exceed 22 inches but not greater than 30 inches in length, add $4.50.

  • Parcels that exceed 30 inches in length add $21.00.

USPS Ground Advantage

  • Parcels that exceed 22 inches but not greater than 30 inches in length, add $4.50.

  • Parcels that exceed 30 inches in length add $10.00.

Nonstandard Volume

USPS Priority & Priority Mail Express

  • Parcels that exceed 2 cubic feet (3456 cubic inches), add $35.00.

USPS Ground Advantage

  • Parcels that exceed 2 cubic feet (3456 cubic inches), add $21.00.

How to calculate cubic feet:

  • Measure the Length, Width and Height in inches rounded down to the nearest 0.25 inch.

  • Multiply the Length * Width * Height (LxWxH) and then divide by 1728.

Nonstandard Characteristics Surcharge

For domestic Priority Mail, Priority Mail Express, and Ground Advantage shipments, you can declare that a package has nonstandard characteristics when you create the shipment. Select this option if the package contains any of the following:

  • A cylindrical tube or roll.

  • A can, or a wooden or metal box.

  • More than 24 ounces of liquid in a glass container, or one gallon or more of liquid in a metal or plastic container.

  • Any other mailable item, including a poly bag, whose contents may shift or that may not maintain the packaging's integrity during processing.

When this option is selected, USPS applies the higher of the Length Fee or the nonstandard-characteristics fee - it does not apply both. Any applicable fee under Nonstandard Volume above is still added on top.

Dimension Non-Compliance Fee

An additional dimension-noncompliance fee is levied on packages greater than 1 cubic foot or 22" in length if dimensions are not provided or inaccurate. This fee plus any fees for non-standard package sizes are assessed via the USPS Automated Package Verification (APV) system.

We want all our customers to understand the USPS non-standard package fees and that they should provide accurate dimensions when creating labels to avoid the non-compliance fee. For additional information visit the Help Center Article: How to Calculate USPS Postage Correctly.
