This comprehensive guide provides actionable strategies, cost analysis, and industry insights to help your business adapt and thrive.

Section 321 Repeal Takes Effect 29 August 2025 — What U.S.–China Shippers Must Do Now

(Section 321 免税撤销即将生效——美中贸易商当下必须采取的行动)

1 · Understanding the Seismic Shift in U.S. Trade Policy

The elimination of Section 321’s de minimis exemption represents the most significant change to U.S. import regulations in over two decades. This policy shift affects not just individual transactions, but the entire ecosystem of cross-border e-commerce, small business importation, and last-mile logistics.

What Exactly Is Changing?

• Executive Order (February 2025) suspended Section 321’s $800 de minimis privilege; the nationwide rollout date is 29 August 2025.
• Only USPS inbound mail keeps simplified paperwork, but even there ad-valorem or specific duties ($80–$200) now apply by origin country.
• CBP’s ACE system begins hard enforcement in production on 12 August 2025, ending the “warning-only” period.

The Historical Context

The de minimis threshold has been a cornerstone of U.S. trade facilitation since the Trade Facilitation and Trade Enforcement Act of 2015 raised it from $200 to $800. This change enabled the explosive growth of direct-to-consumer shipping from Asia, particularly China, where platforms like AliExpress, Temu, and Shein built business models around duty-free small shipments.

Key Statistics:

• In 2019, approximately 1.8 billion packages entered the U.S. under Section 321
• By 2024, this number exceeded 4.2 billion packages annually
• China accounted for roughly 60% of all de minimis shipments
• The estimated revenue loss to the U.S. Treasury: $3.2 billion annually

2 · Industry Impact Analysis — Beyond the Numbers

E-commerce Transformation

The repeal fundamentally alters the economics of cross-border e-commerce. Businesses that thrived on the ability to ship individual items duty-free must now reconsider their entire operational model.

Affected Business Models:

• Dropshipping operations shipping directly from China to U.S. consumers
• Small importers bringing in samples, prototypes, or limited quantities
• Subscription box services sourcing diverse, low-value items internationally
• B2B spare parts suppliers shipping critical components on demand

Supply Chain Consolidation Trend

Industry experts predict a significant consolidation in the supply chain, with smaller players either adapting or exiting the market. This creates opportunities for established logistics providers to offer comprehensive solutions.

“We’re seeing a flight to quality in logistics partnerships. Companies that previously handled customs themselves are now seeking professional guidance,” says Sarah Chen, Director of Trade Compliance at a major 3PL provider.

3 · Cost Impact Analysis — Real-World Scenarios

Understanding the true cost impact requires examining various product categories and shipping patterns. Here are detailed scenarios across different industries:

Scenario 1: Apparel & Fashion

Item: $18 cotton T-shirt, Shenzhen → Los Angeles

Scenario 2: Electronics & Components

Item: $45 smartphone case, Guangzhou → New York

Scenario 3: Health & Beauty Products

Item: $25 skincare serum, Shanghai → Miami

Volume Impact Considerations

The cost impact becomes more complex when considering shipping volume patterns:

Low-Volume Shippers (1-50 packages/month):

• Highest per-unit impact due to minimum fees
• Limited negotiating power with service providers
• May need to exit certain product categories

Medium-Volume Shippers (51-500 packages/month):

• Opportunity to negotiate better broker rates
• Can leverage consolidation strategies
• Investment in compliance technology becomes viable

High-Volume Shippers (500+ packages/month):

• Best positioned to absorb costs through economies of scale
• Can justify investment in FTZ operations
• May gain competitive advantage as smaller competitors exit

4 · Comprehensive Compliance Strategies

Strategy 1: Type 86 “Simplified” Entry Process

Best for: Established importers with predictable product mix and moderate volumes

How it works:

• Automated customs entry for shipments under $800
• Duties and fees still apply, but processing is streamlined

8 · Comprehensive FAQ and Industry Insights

General Questions

Q1: Will USPS parcels still be duty-free?
A: No. Postal shipments retain simplified paperwork but now attract either ad-valorem rates or the new $80–$200 specific tariff by country. However, the administrative burden remains lower than commercial imports.

Q2: Does the exemption still apply to Canada, EU, or Mexico origins?
A: Only until 29 August 2025. After that date, all non-postal origins are dutiable with no country carve-outs currently planned.

Q3: How does CBP track multiple low-value parcels to the same consignee?
A: CBP’s ACE system aggregates shipments by name, address, and tax ID in real time. When combined shipments exceed $800, all packages may be subject to formal entry requirements.

Business Strategy Questions

Q4: Should we increase our minimum order values to offset the additional costs?
A: This is a common strategy, but consider customer price sensitivity. Our analysis suggests that gradual increases (10-15% initially) with clear value communication work better than dramatic price jumps.

Q5: Is it worth investing in FTZ operations for smaller importers?
A: Generally, FTZ operations become cost-effective for importers with annual duty liabilities exceeding $200,000. Smaller importers should consider shared FTZ services offered by 3PLs.

Q6: How do we explain these changes to our customers?
A: Transparency is key. Provide clear information about the regulatory changes, emphasize your commitment to service continuity, and highlight any investments you’re making to minimize impact.

Operational Questions

Q7: What happens to shipments in transit on August 29?
A: CBP has indicated that shipments that departed origin before August 29 may still qualify for Section 321 treatment if they arrive before September 15, 2025. However, this grace period is not guaranteed.

Q8: Can we use multiple consignees to stay under the $800 threshold?
A: No. CBP actively monitors for artificial consignee arrangements and imposes severe penalties for abuse. All shipments must be consigned to their true ultimate consignee.

Q9: How do returns and exchanges work under the new rules?
A: Returns of defective or incorrect merchandise can often be reimported without additional duty under specific CBP procedures. However, documentation requirements are more stringent than under Section 321.
