How to Save Money Using USPS Priority Mail Cubic- Shipping Solutions
There’s no denying the growing trend of ecommerce business and the need to find the most efficient way to ship packages. It’s important for businesses to re-evaluate their shipping strategies and ensure they’re taking advantage of the most cost-effective options. So, read on to learn more about the “secret service” of the USPS® for shipping smaller but heavier parcels.
30 pxIf you ship small but dense packages, USPS® Priority Cubic is the best rate
5 pxPriority Mail® Cubic is a special rate or sub-service of Priority Mail® for smaller packages where a mailer pays based on the size of the mail piece instead of the weight. It has a maximum weight of 20 pounds and the size can be no bigger than 0.5 cubic feet. This rate is not available at the post office and is not available in all online shipping platforms. This rate can only be used by shippers who have access to Commercial Pricing.
30 pxSmall volume shippers can get access even if they don’t ship 50,000 packages per year
5 pxEven small shippers who ship only a few packages can gain access to the USPS Cubic rates if they use a product like FP Parcel Shipping. If you use an online shipping application, chances are you automatically qualify for Commercial Pricing and USPS® cubic.

5 pxIn simplest terms, it’s a dense parcel or a heavy envelope. If you want to measure it yourself, you multiple the length (L) x width (W) x height (H) and then divide the sum by 1728. Note, the maximum dimension of any side is 18”. If that seems complex, don’t worry, applications like FP Parcel Shipping does the calculation automatically for you ensuring accuracy.
