Cubic Pricing with USPS Priority Mail

USPS offers discounted rates on Priority Mail for packages and envelopes that weigh less than 20 pounds and measure less than 0.5 cubic feet in volume. A package doesn't qualify for Cubic Pricing if its length, width or height is over 18 inches. Consider using Cubic Pricing if you typically send small and heavy products such as weights or coffee beans.

When a USPS Priority Mail rate is calculated through Shopify Shipping, both the regular Priority Mail shipping rate and the Cubic Pricing shipping rate are calculated, but only the cheapest option displays. For example, if the Priority Mail rate is 10.70 USD and the Cubic Pricing rate is 14.30 USD, then only the regular Priority Mail rate displays.

Calculating Cubic Pricing for packages

Use the following formula to calculate the cubic volume of a package. If the amount is less or equal than 0.5 cubic feet, then the package uses cubic rates. All measurements must be in inches.

Length (in inches) x Width (in inches) x Height (in inches) / 1728 = cubic feet

For example, you can apply the formula to a standard adult shoe box:

14" x 8" x 5" / 1728 = 0.4 cubic feet

This package is less than 0.5 cubic feet and qualifies for cubic rates.

Calculating Cubic Pricing for soft-pack and padded envelopes

USPS offers separate Cubic Pricing for soft-pack and padded envelopes. You can add small boxes to an envelope as long as the envelope keeps its flat shape. Expandable envelopes don't qualify for the envelope pricing and need to use Cubic Pricing for packages instead.

Use the following formula to determine if an empty envelope or soft-pack qualifies for Cubic Pricing. If the amount is less than 36 inches, then Cubic Pricing applies.

Length (in inches) + Width (in inches) = Total package length

USPS package intercepts

USPS can stop the shipment or redirect your package that is not out for delivery or already delivered.

You can check if your package can be intercepted by entering the USPS tracking number at the Package Intercept page. If the package can be intercepted, refer to the USPS interception instructions for submitting a request to change your shipment.
