What is a shipping surcharge?
Any charge added to the base transportation rate. On a domestic parcel that means address-type fees, destination ZIP fees, fuel, awkward-package handling, oversize charges, address corrections and seasonal demand amounts. Freight contracts call the same category accessorial charges.
How much do surcharges add to a parcel?
It depends entirely on the box. Two cartons holding the same 25 lb quoted $29.52 and $77.56 on UPS Ground from Newark to Atlanta on 2026-07-28, and a 20 lb carton six inches longer quoted $203.72. Address and fuel fees are single dollars by comparison.
Which surcharge catches ordinary shippers most often?
The address pair. Residential delivery is $6.50 at UPS and $6.95 at FedEx, and the delivery area surcharge adds $4.50 to $8.85 when the destination ZIP is on a carrier list holding tens of thousands of entries. USPS charges neither.
Do I have to work these out before I ship?
No. The price our calculator returns for your box and your two ZIP codes is the whole amount collected at checkout, with everything applicable already inside it and SMKlog's charge included. Buy the label as a guest and print it.
