50 lb – 70 lb

How to Ship a 70 lb Package — USPS's Maximum Weight

70 lbs is the maximum weight USPS accepts for packages. UPS and FedEx Ground accept up to 150 lbs — above 70 lbs you're exclusively with private carriers. At 70 lbs, USPS Flat Rate boxes still work and are often the cheapest option for cross-country dense shipments.

Expect $60-100 via USPS Ground Advantage, $55-95 via UPS/FedEx Ground, or a flat $23.90 via USPS Large Flat Rate (if item fits).

Typical Pricing by Service

Service	Zone 2	Zone 8	Transit
USPS Ground Advantage	$58.00-70.00	$95.00-115.00	3-5 days
USPS Priority Mail Large Flat Rate	$23.90	$23.90	1-3 days
UPS Ground	$55.00-68.00	$85.00-110.00	1-5 days
FedEx Ground	$55.00-68.00	$85.00-110.00	1-5 days

Rates are retail / approximate. Commercial accounts and Commercial Plus rates (via Pirate Ship, Shippo, ShippingLabel at scale) typically save 10-30% off these.

Recommended Carrier

Large Flat Rate Box ($23.90) dominates at 70 lb for items that fit the 12×12×5.5 box — this is one of the best deals in shipping. Otherwise UPS Ground Commercial Plus is cheapest. Above 70 lbs, USPS isn't an option; private carriers only.

Dimensional Weight Notes

DIM weight rarely the issue at 70 lb — most items are dense enough that actual weight wins. For bulky 70 lb items (large furniture, equipment), check dimensions carefully.

Packaging for 70 lb

Triple-wall corrugated recommended for durability. Box dimensions 24×18×14 or larger. Heavy-duty tape. Consider pallet/skid shipping at 70+ lb for multi-item shipments.
