Overview

USPS Cubic Pricing offers discounted rates for high-volume shippers with small, heavy packages. Priority Mail packages that weigh less than 20 pounds and measure no more than 0.5 cubic feet in volume are eligible for these rates, as long as you meet the minimum package requirements. This method is specific to stamps.com and is not accessible via the usps.com API. ShipperHQ integrates directly with usps.com, and the following steps will guide you in setting up USPS Cubic Pricing in ShipperHQ.

How to Set Up USPS Cubic Pricing in ShipperHQ

Zones

First, you'll need to define Shipping Zones in ShipperHQ. Contact stamps.com to obtain these zones and enter them into ShipperHQ once defined.

Define Boxes in ShipperHQ

💡 Make sure you have Dimensional Shipping enabled and your Box Definitions entered. USPS Cubic pricing applies to boxes within a cubic feet range of 0.01-0.50. Here's how you can calculate cubic feet for your boxes:

  • Box A: 5x5x5 → 5 x 5 x 5 / 1728 = 0.07 Cubic Feet (Rates from 0.1 column)
  • Box B: 6x6x6 → 6 x 6 x 6 / 1728 = 0.125 Cubic Feet (Rates from 0.2 column)
  • Box C: 8x8x8 → 8 x 8 x 8 / 1728 = 0.296 Cubic Feet (Rates from 0.3 column)
  • Box D: 9x9x9 → 9 x 9 x 9 / 1728 = 0.421 Cubic Feet (Rates from 0.4 column)

⚠️ Boxes over 0.50 Cubic Feet are not eligible for Cubic Pricing.

Setting Up Shipping Rules

With your zones defined and boxes ready, it's time to set up Shipping Rules to apply the discounted Cubic Pricing. You will need 13 Shipping Rules per box.
