How to Ship International Orders from the US Using Buy Shipping and ECMS
Amazon's Buy Shipping now supports international fulfillment from US addresses to UK and EU customers via ECMS carrier, with specific value thresholds, packaging requirements, and a streamlined label purchase process through Seller Central or SP-API.
Overview
Amazon now allows US-based sellers to purchase international shipping labels directly through the Buy Shipping platform on Seller Central. This service enables sellers to fulfill orders from a US address and ship to customers across the United Kingdom, European Union member states, and other supported destinations using the ECMS carrier. For sellers looking to expand internationally without the complexity of overseas warehousing, this is a significant operational tool.
Key Points / What Sellers Need to Know
-
ECMS is the designated carrier — Currently, ECMS is the only carrier available through Buy Shipping for international fulfillment from the US. Sellers must create an ECMS account before using this service, and activation can take up to two business days after registration.
-
Value thresholds apply — The program only covers items below the Import One Stop Shop (IOSS) threshold, which is €150 for EU destinations and £135 for UK shipments. Orders exceeding these amounts must be shipped through alternative channels.
-
Duties must be prepaid — Amazon's policy requires that international customers never have to pay duties upon delivery. Products that would require the buyer to cover duties at receipt are automatically filtered out of the program.
-
Labels are valid for 14 days — Once a shipping label is purchased, it remains active for up to 14 days from the shipping date. Sellers should plan their logistics accordingly.
-
Two purchasing methods available — Labels can be bought either through the Seller Central order interface or programmatically via the SP-API for sellers with automated workflows.
Supported Destinations and Eligibility
The Buy Shipping international program is open to all active Amazon sellers who have a ship-from address in the United States. Supported delivery destinations include the United Kingdom, Germany, France, Italy, Spain, the Netherlands, and other EU member countries. To participate, sellers need an active selling account in good standing and must complete ECMS carrier registration. The program is specifically designed for lower-value items that fall beneath the IOSS duty thresholds, making it ideal for sellers offering lightweight, moderately priced products to European customers.
