Here is the new USPS surcharges starting April 3rd/2022 and my comments.
A fee of $1.50 will be applied to any packages when manifested dimensions are either incorrect or are not provided and the captured dimensions (length, width, height) have a length greater than 22 inches or volume greater than one cubic foot with an accuracy of 1/4"
[Ok fair enough, don't game the system]
Parcels that are longer than 22 inches but less than 30 inches will see a $4.00 surcharge.
[Ok, I can understand that postal carriers are weak and lack the dexterity to hand any package slightly over 22 inches in length]
Parcels that exceed 30 inches in length will incur a $15.00 surcharge and is on top of the charge of $4.00 for being over 22 inches.
[Is the postmaster general totally nuts; all the major carriers allow parcel length up to 48 inches with no surcharges, and even longer if you have the volume to negotiate]
Well USPS will at least accomplish one task; faster delivery because there will be a lot of businesses moving their logistic services to a different carrier, including us.
