USPS First-Class Package 2021 Rate Changes

First-Class Package service has been the most popular and cheapest USPS service to ship packages under 1 lb. Many small and medium-sized business rely on this cost-effective shipping method for small and light packages.

An important element to note is that the First-Class Package Service Commercial rates allow you to ship up to 15.999 oz packages. Retail rates only allow you to ship up to 13 oz packages with the service.

Interestingly, it seems lower weights in First-Class Package Service are seeing some of the greatest increases across this shipping method. For example, packages up to 4 oz going to Zone 4 are seeing shipping rates increase by 10.07%, whereas 13 – 15.999 oz are only increasing by 2.85%.

Regional Rate Shipping 2020 Rate Changes

Regional Rate service is a less-used but useful shipping service. This method lets you ship using preset boxes you can order online, and the rate is cheaper when shipping short distances. Both Regional Rate Box A and B rates increased across all zones. Regional Rate shipments are mainly designed to be shipped to Zones 1-4, and that is certainly reflected in the Zone 9 increases below.

Parcel Select Ground 2021 Changes

Parcel Select is also a less-often used USPS shipping method. It’s slower and doesn’t offer the included tracking and insurance that comes with USPS Priority Mail. There are instances where it is cheaper, but many small and medium-sized business are willing to spend the extra cents to have those options available. That being said, Parcel Select Ground can be a way to shave shipping costs and improve margins. The rates for Parcel Select Ground will see an average 1.2 percent increase, while prices for Parcel Select Lightweight will increase by 20.0 percent.

Here we’ve used an example of a 5 lb package to illustrate the increases for 2021. As you can see, Parcel Select Ground is the only method where we’re seeing an actual decrease in some instances.
