USPS Cubic Pricing is a way for high volume shipping customers to get cheap shipping rates on small but heavy packages. For customers to qualify for this affordable shipping option, packages must weigh 20 pounds or less and measure no more than 0.5 cubic feet.
With Cubic Pricing, customers only pay for the dimensions and shipping distance of an outgoing shipment. Since weight isn't a part of the shipping rates calculation for USPS Cubic Pricing, it's a great way for businesses to lower their shipping costs on heavier packages. Since all major carriers — including USPS, FedEx, UPS, and DHL — base their shipping rates on weight, Cubic Pricing provides savvy businesses the opportunities to reduce their shipping rates on their heavier packages.
Cubic Pricing is measured by calculating:
Length x Width x Height / 1728 = Cubic Feet (the longest dimension may not exceed 18", or the package will be disqualified from Cubic Pricing rates)
Based on the cubic feet measurement, your package will fall into one of five tiers:
