Compiled by Radif Partners · How the prices are built
Shipping a heavy package with the Postal Service is possible up to 70 pounds, and the price climbs with each pound and each zone. A 30-pound package by Ground Advantage costs $44.45 at a counter in zone 2 and $120.30 in zone 8; with an online label the zone 8 price falls to $104.30. From January 17, 2027 the same counter price would be $123.10, with the proposed base price and the 11% fuel surcharge. Two alternatives often beat it. A Large Flat Rate Box costs $36.10 whatever it weighs up to 70 pounds and wherever it goes, if the items fit in it. And books or recorded media go by Media Mail for $25.76 at 30 pounds, any distance. Above 70 pounds the Postal Service accepts nothing: split the load into two boxes. A large box can also be charged on its size rather than its weight.

Pack it to arrive
The Domestic Mail Manual asks for packaging that withstands normal handling: cushion fragile items, keep the contents from shifting and brace heavy items so they do not damage other mail. A heavy box in a weak carton is the first to split. Use a double-wall box for loads near the limit and tape every seam.

Above 70 pounds, split the load. Splitting costs more: two boxes of 35 pounds cost $269.30 by Ground Advantage to zone 8 at a counter, one box of 70 pounds $204.30. Below the limit, keep one box; above it, there is no other way. Weigh each one after packing; the price goes by the pound, any fraction counting as a full pound.
If the box is large as well as heavy, check the size weight and the size limits. The flat rate page shows from which zone the Large box wins for your weight.
