The Postal Service has filed a request with the Postal Regulatory Commission to include several international mailing services in the Competitive Product List. These services are part of a negotiated service agreement, which includes International Priority Airmail and Commercial ePacket, among others. The notice was published on January 4, 2021, and additional details can be found on the Postal Regulatory Commission's website.
Simple Explanation
The Postal Service wants to add some new ways to send mail to other countries by air and other methods into a list of special deals, but the notice doesn't tell us much about what these deals will cost or how they will help.
