The suspension of the US de minimis rule has led to over 30 countries, including Japan, temporarily halting postal services to the United States.
Overview of De Minimis Rule Suspension
As of 12:01 AM Eastern Time on August 29, 2025, the de minimis rule application for goods entering US customs has been suspended. This means tariffs now apply to small parcels valued at $800 or less, which were previously duty-free.
Grace Period and Practical Challenges
- Grace Period: Until end of February 2026
- Grace Content: Choice between specific or ad valorem duties for EMS using international postal network
- Issues: Procedures for carriers and postal operators remain unclear, making operations extremely difficult
Country Responses
Japan Post Measures (Started August 27, 2025)
Temporary suspension of accepting US-bound mail:
- Target Items:
- Personal gifts exceeding $100 in value
- Commercial goods for consumption
- Affected Services:
- Small packets
- Parcels
- EMS (goods)
Impact on Businesses
Cross-border e-commerce operators particularly affected:
- Japan-to-US shipping limited to international courier services only
- Increased costs and reduced shipping options
Requirements for International Courier Services
Import procedures required for US customs:
- Submission of import declaration through ACE electronic filing system
- Proper HTS code selection
- Country of origin verification
- Same paperwork as general cargo imports
Future Outlook
With over 30 countries halting postal services, the US cross-border e-commerce market faces significant disruption. Unless operational procedures during the grace period are clarified, this situation is likely to continue, forcing a restructuring of international logistics.
Businesses must urgently consider alternative shipping methods and strategies to address increased costs.
