2018 USPS Priority Mail International Shipping Rate Increase: a Deep Dive

By Rob Zaleski, Jan 9, 2018

On January 21, 2018 the new USPS rates go into effect. Most Shipping Services products will average a 3.9% price increase across the board, including the USPS Priority Mail International rate increase. In this article, we’ll do a deep dive into what exactly Priority Mail International is, who should use it, and what kind of increases we’ll be seeing in 2018.

What is Priority Mail International?


Priority Mail International (PMI) offers a faster delivery time than First-Class Mail International, typically arriving between 6 and 10 days. It is not, however, the fastest method. That would be Priority Mail Express International.

While First Class International is the cheapest method to ship internationally, your package must be less than 4 lbs. and the delivery time depends completely on the destination. With Priority Mail International, you can ship packages up to 70 lbs. with more reliability. Tracking information is available, and delivery confirmation is included in the cost of PMI. The shipping cost is determined by how far the package is traveling, though Flat Rate options are available when using Flat Rate boxes.

Priority Mail Express International comes with a money-back guaranteed delivery window, allowing you to apply for a refund if your package is late. This option does not come with Priority Mail International.

Priority Mail International Features:

  • Send packages that weigh up to 70 lbs.
  • Use custom packaging or boxes available from the USPS
  • Shipping cost will be determined by the distance the shipment is traveling
  • Tracking is available through the Track & Confirm tool on usps.com
  • Delivery confirmation included

Who should use Priority Mail International and when?

If you need a more reliable delivery window with tracking than First Class International can offer, but don’t need an absolute guarantee, Priority Mail International will be your best bet. If your packages typically weigh more than 4 lbs., you won’t be able to use First Class International shipping, so you will have to use PMI as your default. This shipping method serves as an intersection of cost and speed of delivery.

What are the 2018 Priority Mail International shipping rates increases?


Across the board, the Priority Mail International shipping rate increases in 2018 are also about 3.9%. Below, you can see the amount each price group increased for every Flat Rate international shipping option.

The number of options for international shipping are far too many to show everything here, but there isn’t a single weight/zone combination that was less than a 2% increase, so you should certainly expect your costs to go up in 2018 for packages leaving the U.S.

That being said, Priority Mail International still offers the best combination of time and cost-savings compared to other methods and carriers.
