Beginning on April 3, 2022, USPS will impose surcharges known as “non-standard fees” on certain shipments. Imposing surcharges is a common practice for other shipping carriers, and additional fees are to be expected whenever you ship with UPS in particular. However, since USPS has never imposed these sorts of surcharges on packages before, many shippers might be in for a rude awakening.
The non-standard service fees are surcharges that apply to shipments when the dimensions are greater than certain lengths. In essence, USPS is charging these fees for larger packages that take up more space on their trucks. The more space a package takes up, the less opportunities USPS has to transport other packages in the same truck, earn more revenue, and operate more efficiently.
