Executive Summary
The suspension of Section 321 de minimis treatment, effective August 29, 2025, marks the most significant transformation in U.S. import policy in decades. All international shipments previously eligible for duty-free entry under the $800 threshold now require formal customs processing and duty payment. This fundamental shift affects millions of packages annually and requires immediate operational adjustments across the entire international trade ecosystem.

The End of Section 321 De Minimis: Navigating the New Era of U.S. Import Policy

(Section 321德minimis制度的终结：美国进口政策的新时代)

1 · Understanding the Regulatory Transformation

The elimination of Section 321 de minimis treatment represents far more than a technical customs adjustment. This policy change fundamentally alters the economic landscape for international e-commerce, reshapes logistics operations, and creates new compliance requirements that affect every stakeholder in the global supply chain.

Historical Context and Policy Evolution

The De Minimis Framework Legacy: For decades, the Section 321 exemption under 19 U.S.C. § 1321 provided duty-free treatment for low-value shipments, originally designed to reduce administrative burden on customs authorities and facilitate small-scale international commerce.

Volume Growth and System Strain: The explosive growth in international e-commerce transformed de minimis from an administrative convenience into a major trade channel:

• 2015 Baseline: 134 million packages entered under de minimis
• 2024 Volume: Over 1.36 billion packages, representing a ten-fold increase
• Daily Processing: CBP handled over 4 million de minimis packages daily
• Revenue Impact: Billions in uncollected duties and missed enforcement opportunities

Security and Compliance Challenges: The scale of de minimis shipments created significant enforcement challenges:

• Contraband Concerns: 90% of cargo seizures originated from de minimis shipments
• Narcotics Trafficking: 98% of narcotics seized from cargo fell under de minimis exemption
• Counterfeit Goods: 97% of counterfeit items seized came through de minimis channels
• Limited Oversight: Minimal documentation requirements hindered regulatory oversight

Executive Order 14324: The Policy Foundation

Comprehensive Suspension Authority: Executive Order 14324, signed July 30, 2025, provides the legal framework for eliminating de minimis treatment by invoking emergency authorities under the International Emergency Economic Powers Act (IEEPA).

National Security Rationale: The administration justified this action as necessary to address “unusual and extraordinary threats to the national security, foreign policy, and economy of the United States,” specifically citing:

• Economic Security: Protection of domestic industries from unfair competition
• Revenue Collection: Ensuring proper collection of duties and taxes
• Supply Chain Security: Enhanced oversight of international supply chains
• Law Enforcement: Improved ability to detect and interdict contraband

Implementation Timeline:

• February 1, 2025: Initial suspension for China and Hong Kong
• July 30, 2025: Executive Order 14324 signed, extending globally
• August 29, 2025: Comprehensive implementation at 12:01 AM EDT
• February 28, 2026: Mandatory transition to ad valorem duty methodology

2 · Operational Impact and Compliance Requirements

The suspension of de minimis treatment creates immediate operational challenges and long-term strategic considerations for all participants in international trade.

Immediate Compliance Obligations

Entry Filing Requirements: All shipments previously eligible for de minimis treatment must now comply with formal customs entry procedures:

Documentation Standards:

• Commercial Invoices: Accurate value declarations and detailed product descriptions
• Entry Forms: Proper completion of CBP Form 7501 or electronic equivalent
• Country of Origin Certificates: Verification of manufacturing location and supply chain
• Import Licenses: Product-specific permits and certifications where required

System Processing Changes:

• ACE Integration: All entries must be filed through the Automated Commercial Environment
• Type 86 Elimination: Section 321 Entry Type 86 filings are no longer accepted
• Paper Prohibition: Paper informal entries are not permitted for most shipments
• Electronic Filing: Mandatory electronic submission through qualified systems

Duty Collection Methodologies

Dual-Track Assessment Framework: CBP has established two approaches for duty collection, providing operational flexibility while ensuring comprehensive revenue recovery:

Ad Valorem Assessment: Traditional percentage-based duties calculated on shipment value:

• IEEPA Rate Application: Duties based on applicable IEEPA tariff rates by country
• Value-Based Calculation: Proportional assessment reflecting actual shipment economics
• Documentation Requirements: Comprehensive value verification and supporting records
• Audit Compliance: Full documentation required for customs examination

Specific Duty Assessment: Fixed-rate structure providing cost predictability:

Strategic Considerations:

• Cost Predictability: Fixed rates enable accurate pricing models
• Processing Efficiency: Simplified calculation reduces clearance time
• Temporary Availability: Option expires February 28, 2026
• Volume Economics: Most cost-effective for lower-value shipments

Postal Network Special Provisions

International Mail Exception: Shipments through international postal networks receive modified treatment pending full implementation:

• Duty Collection Required: Duties must be collected despite simplified procedures
• Carrier Methodology Choice: Postal operators may select between assessment approaches
