This article explains USPS rate calculations in Shipbridge.
USPS Cubic Rates
ShipBridge lets you calculate USPS rates, including cubic pricing. USPS Cubic Pricing provides discounted rates to high volume shipping customers for small, heavy packages. Priority Mail packages measuring less than 20 lbs in weight and 0.5 cubic feet in volume, with no dimension longer than 18 in, are eligible for Cubic Pricing as long as you meet the minimum package requirements. For these packages, customers will pay shipping costs for the actual size of the package and the shipping distance instead of its weight.
Compared to other shipping carriers, like FedEx or UPS, which only offer pricing based on weight and distance, USPS Cubic Pricing is a great alternative to help lower your shipping costs. To qualify for Cubic Pricing, customers must ship over 50,000 packages a year.
Calculate Cubic Prices
Shipbridge saves you time by letting you calculate USPS rates, including cubic pricing.
The cubic pricing for your USPS package is measured by calculating: Length x Width x Height / 1728 = Cubic Feet
Once you have the cubic feet measurement, your package will fall into one of the following five tiers:
|Tier 1||Packages up to .10 cubic feet|
|Tier 2||Packages more than .10 and up to .20 cubic feet|
|Tier 3||Packages more than .20 and up to .30 cubic feet|
|Tier 4||Packages more than .30 and up to .40 cubic feet|
|Tier 5||Packages more than .40 and up to .50 cubic feet|
To use this cubic pricing in Shipbridge, package dimensions must be included on the shipping label requests. To enable this in Shipbridge:
- Go to Menu > Options > Shipping tab.
- Check Populate package dimensions in shipping labels requests.
- Click Save.
