Section 321 Suspended: A Timeline of the De Minimis Shutdown

Written by ODW Logistics | Oct 30, 2026, 2:25:11 PM

 With Section 321 suspended since August 29, 2025, shipments valued at $800 or less no longer clear U.S. customs duty-free, and two Customs and Border Protection (CBP) interim final rules published June 24, 2026 made that suspension indefinite.

Section 321 of the U.S. Tariff Act has long provided shippers with a significant cost-saving opportunity, allowing low-value shipments (valued under $800) to enter the U.S. duty-free. This exemption has been widely used by e-commerce businesses, cross-border retailers, and logistics providers to streamline imports and reduce costs.

The President signed Executive Order 14324 on July 30, 2025, and de minimis treatment ended for shipments from all countries on August 29, 2025. For background on how the exemption worked, read ODW's guide to Section 321. This guide will help businesses understand the impact of the Section 321 suspension, what it means for supply chains, and how to navigate the changes effectively.

Section 321 Suspended: What Changed and When

The suspension began by executive order in 2025 and was written into CBP regulation in June and July 2026. The table lists each step.

Date

Event

What it means

July 30, 2025

Executive Order 14324 signed

The President orders the suspension of de minimis treatment.

August 29, 2025

Suspension takes effect

Duty-free treatment under Section 321 ends for shipments from all countries.

February 20, 2026

The suspension continues, including for international mail, and CBP keeps collecting applicable duties.

June 24, 2026

Interim final rules published; the non-postal rule and the mail suspension take effect

Shipments valued at $800 or less that arrive by any mode other than mail must use formal or informal entry.

July 24, 2026

Rest of the international mail rule takes effect

A new postal informal entry process applies to merchandise valued at $2,500 or less.

October 14, 2026

CBP extends a mail compliance date

The date for certain mail to meet formal entry requirements moves from October 22, 2026 to January 20, 2027.

July 1, 2027

Scheduled end of the statutory exemption

Legislation terminates the exemption on that date.

Why Was Section 321 Suspended?

Several factors led to this decision, including:

  • Concerns Over Compliance and Fraud – A rise in companies exploiting the exemption to avoid duties raised alarms within regulatory agencies.
  • Trade Policy Adjustments – Policymakers aimed to tighten import controls and ensure a fair competitive landscape for domestic businesses.
  • Security and Supply Chain Transparency – The government seeks greater visibility into shipments to prevent illicit trade and ensure safety.

What Do the June and July 2026 Interim Final Rules Require?

The rules require duty-paying entries for low-value shipments in place of Section 321. An interim final rule takes effect right away while CBP accepts public comment, and these two rules set separate paths for freight and mail.

The non-postal rule comes first. Effective June 24, 2026, it suspends the exemption for every mode except the international postal network, so shipments valued at $800 or less must use formal or informal entry. Informal entry generally covers merchandise valued at $2,500 or less, and formal entry applies above that.

The mail rule comes second. It suspended the exemption for international mail on June 24, 2026, and its postal informal entry process for merchandise valued at $2,500 or less took effect on July 24, 2026. Some mail, including goods subject to partner government agency requirements or additional chapter 99 duties, will need formal entry once a delayed compliance date arrives, which CBP has extended to January 20, 2027.

Two narrow exemptions come third. The rules leave the exemptions for bona fide gifts and for personal or household articles that travelers carry unchanged, but they are rarely a planning option for commercial importers.

CBP has also proposed further changes to informal entry filing and bonds. Those proposals are not final, and ODW's De Minimis Changes in 2026 article tracks them.

Immediate Impact on Shippers

The suspension of Section 321 has significant consequences for shippers, particularly those reliant on duty-free imports. Because the rules are indefinite, shippers should plan for these effects to continue.

Higher Import Costs

Without Section 321, shipments valued under $800 are now subject to duties and tariffs, increasing the overall cost of doing business. Companies must factor in these additional expenses when pricing products and planning logistics. Informal entry still carries duty, so landed cost on formerly duty-free orders deserves a product-by-product review.

Customs Clearance Delays

Shipments that previously moved swiftly under Section 321 now require formal or informal entry, leading to potential delays at ports of entry. Businesses must adjust fulfillment timelines to account for longer clearance times.

Increased Compliance and Documentation Requirements

Shippers must now adhere to stricter regulatory requirements, including proper classification, valuation, and record-keeping. Failure to comply could result in penalties, shipment holds, or other disruptions.

Key Considerations for Shippers

Regulatory Compliance

To avoid costly penalties, businesses must ensure full compliance with updated customs regulations. Proper documentation, including invoices, HS codes, and country-of-origin details, will be critical to smooth operations.

Cost Implications and Mitigation Strategies

With duties now applied to shipments that once qualified for Section 321, businesses need strategies to minimize cost increases, including:

  • Consolidating shipments to optimize freight costs.
  • Exploring duty drawback programs or bonded warehousing solutions.
  • Adjusting pricing models to account for added expenses.
  • Reviewing the domestic U.S. distribution network to optimize fulfillment speed and cost.

Operational Challenges

Cross-border e-commerce and supply chain management will become more complex. Companies must rethink inventory distribution, order fulfillment processes, and warehouse locations to adapt to the new rules.

Frequently Asked Questions

Is Section 321 still active?

No. The $800 duty-free exemption is suspended for every mode, including international mail, and CBP's interim final rules make the suspension indefinite. Only the separate exemptions for bona fide gifts and travelers' personal or household articles remain. ODW Logistics helps shippers plan distribution, duty, and compliance around the change.

When was Section 321 suspended?

The executive order was signed on July 30, 2025, and the suspension took effect on August 29, 2025. CBP's interim final rule for non-postal shipments took effect on June 24, 2026. Its mail rule took effect in two steps, with the suspension on June 24, 2026 and the postal informal entry process on July 24, 2026.

What replaces Section 321 for shipments under $800?

Most shipments now use informal entry when valued at $2,500 or less, and formal entry above that. Both owe duty. The owner, the purchaser, or a licensed customs broker typically files the entry, and ODW Logistics supports shippers with compliance guidance and distribution planning around it.

Is the de minimis suspension permanent?

Not formally, but it is indefinite. CBP's rules set no end date, and legislation is scheduled to terminate the statutory exemption on July 1, 2027. Shippers should plan for duty-paid entry as the baseline and watch for further CBP rulemaking.
