International Postage Rates

What Are International Postage Rates?

It goes without saying that the first-class international postage rates and standard-class international postage rates are different, as the former is much faster than the latter. That being said, first-class and standard-class international postage rates are subject to further variations depending on a number of factors.

Typically, it is seen that the packages or posts you send directly from the Post Office are the most expensive of the lot. The international postage rates are much cheaper when it comes to both Commercial Base Pricing and Commercial Plus Pricing. You can get the Commercial Base Pricing for your international postage rates if you buy and print shipping labels with an online postage service provider (stamps.com, for example).

You can only get Commercial Plus Pricing for your international postage rates if you are a high-volume shipper. For this international postage rate to be effective, the shipper needs to enter into a Customer Commitment Agreement with the USPS. The shipper can also access this rate by meeting designated volume thresholds. This could be especially easy for a PostGrid who deals with bulk postage mails regularly.

International Postage Rates From the US

Global Express Guaranteed Shipments

The Global Express Guaranteed or GXG is the fastest option available at your disposal for international shipping. The GXG shipment boasts a short delivery time of 1-3 days to over 190 countries around the globe. What makes it even more reliable is the fact that they offer a money-back guarantee with a date-certain delivery. FedEx Express provides international transportation and delivery for GXG postage.

Besides the quick delivery, GXG also comes with all the USPS's standard advantages, such as tracking to all destinations and insurance for up to $100. You even get a free GXG shipping Kit with GXG stickers, labels, and envelopes. The international postage rates for GXG packages are not fixed and are liable to change depending on multiple factors, including size, shape, weight, and distance.

GXG Package Weight & Dimensions

Weight: The minimum weight for a GXG package is 0.5 lbs with a maximum weight of 70 lbs.

Dimensions: The maximum combined length and girth (the distance around the thickest part) of your GXG package is 108 inches. This means your GXG package can have a maximum length of 45 inches, 46 inches high, and 35 inches wide.

GXG International Postage Rates

The pricing starts from $74.95 at the Post Office, whereas both the Commercial Base and Commercial Plus pricing would only cost you $56.10.

The price is further subject to changes based on your shipment size, dimension, and destination country. The international postage rate for GXG packages could go as high as $1,158 for retail mailers and $1,100 for commercial.

Global Express Guaranteed Shipments (Suspended)

The Global Express Guaranteed or GXG used to be the fastest option available at your disposal for international shipping. It featured a short delivery time of one to three days to over 190 countries around the globe. Also, there was a money-back guarantee with a date-certain delivery. 

FedEx Express used to provide international transportation and delivery for GXG postage. However, the USPS officially suspended Global Express Guaranteed (GXG) service on September 29, 2024. So, the next fastest option is Priority Mail Express International, which delivers mail within three to five business days.

Priority Mail Express International

If you are looking for an international postal service that is fast and reliable while still being affordable, Priority Mail Express International is your best choice. The delivery period for this package is just 3 to 5 business days, and more importantly, they come with flat-rate shipping as well. You can avail of this service for your home or work purposes and send your posts to over 190 countries.

Priority Mail Express International can be the ideal choice for companies that often send out envelopes to their customers or employees as it allows you to use Flat Rate Envelopes. The Flat Rate Envelopes allows you to pay one price for your posts as long as the weight does not exceed 4 lbs. In this case, the variation in the international postage rates is based on the destination alone.

Furthermore, Priority Mail Express International also offers a money-back guarantee similar to the one we saw in GXG packages. The only difference is that it only applies to select destinations. The select destinations include almost all major countries, including Australia, Canada, France, China, and many more. The international postage rates to Australia may not necessarily be the same as the USA's international postage rates. You can also get insurance of up to $100 on documents and up to $200 on merchandise.

As you may have already guessed, Priority Mail International is an economical alternative to your postage service requirements. What's more attractive about USPS's Priority Mail International is that you can use free Flat Rate Boxes and Envelopes regardless of the box weight as long as it is below 70 lbs.

FAQs

Do I Need to Fill Out a Customs Form for International Mail?

You must fill out a customs declaration form if you send anything other than a standard letter or postcard. USPS provides PS Form 2976 (for smaller items like First-Class Package International Service) and PS Form 2976-A (for Priority Mail International or heavier packages). Both these forms require you to declare the shipment's content, value, and purpose, and they must be attached to the package's exterior.

What Can’t I Send in International Mail?

Each country has its import restrictions and prohibitions. USPS adheres to these rules and regulations when sending international mail. Some commonly prohibited items include aerosols, perishables like fresh food, currency or coins, lithium batteries (in some countries), medications, etc. You can visit the USPS International Mail Manual to get the complete list for a specific country.

Why Is the Postage Rate Different for Each Country?

How much postage a country charges depends on the distance between the source and destination and the delivery infrastructure. Postage in some countries might be expensive due to customs handling, remote delivery areas, or security requirements. In some countries, the flat rate might vary if an extra fee, like customs duties or taxes, is applied at the destination.

Are Customs Duties and Taxes Included in the Postage Price?

USPS does not charge for customs duties and taxes since they are the recipient's responsibility. Some countries require payment upon successful delivery, and the post office will only release the package once it has received the payment.

What Is the Most Affordable Mailing Service to Send a Letter Internationally?

The USPS First-Class Mail International (FCMI) is the most economical mailing service to send standard letters and postcards worldwide. Above all, a single Global Forever® only costs $1.70. However, you don’t get any tracking feature with this service.
