Executive Summary
The elimination of the U.S. Section 321 de minimis exemption represents one of the most significant transformations in international trade policy in decades. Effective August 29, 2025, all goods entering the United States—regardless of value—now require full customs clearance and duty payment. This fundamental shift has triggered a cascade of responses from postal services worldwide, reshaping global logistics operations and creating new challenges and opportunities for businesses engaged in international commerce.

The Global Impact of De Minimis Repeal: A Comprehensive Guide for Logistics Professionals

(德最小值豁免废除的全球影响：物流专业人士综合指南)

Understanding the De Minimis Framework and Its Historical Context

What Was the De Minimis Exemption?

The Section 321 de minimis exemption, codified under 19 U.S.C. § 1321, allowed shipments valued under $800 to enter the United States duty-free without formal customs processing. Originally designed as an administrative convenience to reduce paperwork burden on customs authorities, this policy became a cornerstone of international e-commerce growth over the past decade.

Key features of the former system:

• Duty-free threshold: Goods valued under $800 entered without paying customs duties
• Simplified processing: Minimal documentation requirements compared to formal entries
• Administrative efficiency: Reduced burden on both importers and customs authorities
• E-commerce catalyst: Facilitated growth of cross-border online retail

The Scale of Impact

The magnitude of commerce flowing through the de minimis channel had reached unprecedented levels:

• Volume explosion: From 134 million packages in 2015 to over 1.36 billion in 2024
• Daily processing: U.S. Customs and Border Protection (CBP) handled over 4 million de minimis packages daily
• Revenue implications: Billions in annual duty revenue that went uncollected
• Security concerns: 90% of cargo seizures originated from de minimis shipments

The Policy Transformation: Executive Order 14324

Regulatory Foundation and Implementation Timeline

President Trump’s Executive Order 14324, signed on July 30, 2025, eliminated the Section 321 exemption under the authority of the International Emergency Economic Powers Act (IEEPA). The administration justified this sweeping change by citing national security concerns and the need to address “unusual and extraordinary threats to the national security, foreign policy, and economy of the United States.”

Implementation phases:

• February 1, 2025: Initial suspension for China and Hong Kong
• July 30, 2025: Executive Order 14324 signed, extending globally
• August 29, 2025: Comprehensive implementation across all countries
• February 28, 2026: Mandatory transition to ad valorem duty methodology

Dual-Track Duty Collection System

The new framework introduces two methodologies for duty assessment, providing operational flexibility while ensuring comprehensive revenue collection:

Method 1: Ad Valorem Assessment

• Traditional percentage-based duties calculated on shipment value
• Reflects actual economic impact of trade
• Requires accurate valuation and country of origin determination
• Long-term sustainable approach beyond temporary measures

Method 2: Specific Duty Assessment

• Fixed-rate structure based on origin country’s tariff classification
• $80-$200 per package depending on applicable tariff rates
• Simplified processing with predictable costs
• Available only until February 28, 2026

Global Postal Service Response: A Worldwide Suspension

European Postal Networks

The impact on European postal services has been swift and comprehensive:

Major European suspensions:

• Switzerland: Swiss Post suspended most U.S.-bound services, citing uncertainty over duty collection procedures
• United Kingdom: Royal Mail temporarily halted small packet services while transitioning customers to tracked options
• France: La Poste restricted lower-cost services and warned of potential delays
• Germany: Deutsche Post/DHL limited services, implementing additional fees for U.S. shipments
• Nordic countries: Norway, Sweden, and Denmark suspended various parcel categories

Asia-Pacific Market Disruption

Asian postal services, traditionally major conduits for U.S.-bound e-commerce, have implemented significant restrictions:

Key regional responses:

• Australia: Australia Post suspended parcel services, citing customs processing risks
• Japan: Japan Post announced suspension just two days before implementation
• South Korea: Korea Post introduced delays and surcharges pending system updates
• China: China Post limited services to select courier channels with enhanced compliance

Americas and Global Coordination

Even within the Americas, postal services have struggled to adapt quickly:

Regional adaptations:

• Canada: Canada Post introduced surcharges on all U.S.-bound parcels
• Mexico: Correos de México restricted economy services, redirecting to express options
• Global pattern: Over 20 national postal operators implemented some form of restriction

Understanding the Operational Challenges

Why Postal Services Suspended Operations

The suspension of postal services worldwide stems from several operational challenges that traditional postal networks were not equipped to handle:

Delivered Duty Unpaid (DDU) Model Limitations Most postal services operate under DDU terms, where duties are collected upon delivery. The new U.S. requirements demand upfront duty calculation and payment—a fundamental operational shift requiring:

• Advanced duty calculation systems
• Integration with U.S. customs platforms
• Financial guarantees and bonding arrangements
• Real-time data transmission capabilities

Regulatory Uncertainty and Compliance Risk Postal operators faced significant gaps in guidance from U.S. authorities regarding:

• Electronic data submission requirements
• Liability allocation for duty collection errors
• Timeline expectations for system implementation
• Financial responsibility for returned shipments

Infrastructure and Technology Gaps Traditional postal networks lacked the sophisticated technology infrastructure required for:

• Accurate duty calculation across thousands of product categories
• Real-time integration with CBP systems
• Customer communication about additional costs
• Financial processing for duty collection

Private Courier Adaptation: A Study in Preparedness

Why Private Couriers Succeeded

Unlike postal services, major private courier companies—FedEx, UPS, and DHL—successfully adapted to the new requirements due to several advantages:

Established Infrastructure

• Delivered Duty Paid (DDP) capabilities: Existing systems for upfront duty calculation
• Technology platforms: Sophisticated customs management systems
• Financial frameworks: Established bonding and payment procedures
• Regulatory expertise: Dedicated customs compliance teams

Business Model Alignment

• Premium pricing: Cost structure that accommodates compliance expenses
• Customer relationships: Direct relationships enabling clear communication
• Service integration: Comprehensive logistics solutions including customs clearance
• Global operations: Standardized processes across multiple countries

Market Positioning and Opportunities

The postal service suspensions have created significant opportunities for private couriers to capture market share previously dominated by postal networks. This shift represents a fundamental restructuring of the international small package market.
