The US postal system has experienced a dramatic 80% decline in international mail traffic following recent policy shifts, particularly the end of the de minimis exemption. This change has raised many questions about how it impacts mail delivery, international trade, and postal operations worldwide. Below, we explore the reasons behind this drop, how postal operators are responding, and what it means for your mail and packages.
-
Why did US postal traffic drop so much?
The sharp decline in US postal traffic—around 80%—happened after the US ended the de minimis exemption for low-value parcels. This exemption previously allowed small packages to enter duty-free, making international shipping easier and cheaper. Its removal means more parcels now require customs clearance and duties, causing delays and reducing the volume of international mail sent to the US.
-
What is the de minimis exemption and why was it removed?
The de minimis exemption is a rule that allowed parcels under a certain value to enter the US duty-free. It was in place since 1938 to facilitate small international shipments. The US government removed this exemption on August 29, 2025, citing concerns over tariff evasion and illegal drug smuggling. This change shifts the responsibility for duty collection onto carriers and customs, complicating international mail processing.
-
How are postal operators responding to the policy change?
Many postal operators and courier services have suspended or reduced their international services to the US due to operational disruptions and increased customs procedures. Some are developing new technical solutions to handle the increased customs workload, while others are adjusting their routes and services to cope with the new regulations. The UN's postal agency is also working on measures to restore mail flow and reduce delays.
-
What does this mean for international mail delivery to the US?
International mail to the US is now facing longer delays, higher costs, and reduced service options. Many small parcels that previously arrived duty-free are now subject to customs checks and duties, which can slow down delivery times. This change affects consumers, businesses, and international shippers, who may need to adjust their shipping strategies or expect longer wait times.
-
Will the US policy change affect mail from the US to other countries?
While the policy primarily impacts international mail coming into the US, it can also influence outbound shipments, especially if carriers face new logistical challenges. However, the main disruption is on incoming mail, with many countries and postal operators adjusting their operations to manage the increased customs requirements and maintain service levels.
-
Is there any way to avoid delays or extra costs?
To minimize delays and costs, senders should check the latest shipping regulations and consider using carriers that have adapted to the new rules. Clearly declaring the contents and value of parcels can also help speed up customs processing. Staying informed about updates from postal services and choosing expedited options where available can help ensure your mail arrives faster.
