This article explains what USPS cubic pricing is and how to utilize it within your parcel program
USPS Cubic Pricing is a special shipping rate offered by the United States Postal Service (USPS) for small, dense packages. It is specifically designed to benefit shippers who send parcels that have a high weight-to-size ratio. Cubic Pricing can be a cost-effective option for shipping small but heavy items.
The traditional method of pricing packages is based on weight and dimensions, where the package's size plays a significant role in determining the shipping cost. However, for small but heavy packages, the dimensional weight pricing may result in higher shipping costs, even though the package takes up relatively little space in the postal vehicles.
Cubic Pricing, on the other hand, is based on the volume (cubic size) of the package rather than its weight or dimensions. USPS uses a tiered system, and the rates are determined by the package's cubic feet or inches (length x width x height) and the distance it is being shipped.
To be eligible for USPS Cubic Pricing, a package must meet specific requirements, such as weighing less than 20 pounds and measuring less than 0.5 cubic feet (1728 cubic inches) in volume.
Cubic Pricing can be an excellent option for businesses shipping small, heavy items, as it often provides significant cost savings compared to traditional weight-based pricing. However, keep in mind that it may not be the best option for larger or lighter items. As with any shipping option, it's essential to compare rates and choose the service that best fits your specific shipping needs.
