Currently, the Postal Service only requires mailers to include accurate parcel dimensions in a manifest (Shipping Services File (SSF) or other approved electronic documentation) when the dimensions exceed 1 cubic foot or 22 inches in length. Failure to comply with this requirement, would subject the parcel to the Dimension Noncompliance Fee. The Postal Service is proposing to expand the current standard in the Domestic Mail Manual by requiring mailers to always include accurate dimensions (length, width, and height) for parcels included in a manifest. Dimensions would not be required for Flat Rate priced pieces or USPS Returns^® pieces. Failure to comply with the expanded requirement, would continue to subject the parcel to the Dimension Noncompliance Fee. This proposal would also continue to only apply to commercial Priority Mail Express^®, Priority Mail^®, USPS Ground Advantage^®, and Parcel Select^®, products.
