De Minimis Rule & Section 321: The Complete Guide for Importers

What Is the De Minimis Rule?

The de minimis rule is enshrined in Section 321 of the Tariff Act of 1930 (codified at 19 U.S.C. §1321) and gives U.S. Customs and Border Protection (CBP) the authority to waive the collection of duties and taxes on shipments of low value. The logic is purely administrative: the cost of collecting a $12 duty on a $40 phone case exceeds the revenue collected. Rather than clog the ports processing tens of millions of these entries, Congress decided to simply forgo the duty collection entirely.

For most of the 20th century, the de minimis threshold was $200 — modest enough that it applied to travelers returning from abroad with souvenirs, not to commercial trade. That changed dramatically with the Trade Facilitation and Trade Enforcement Act (TFTEA) of 2015, which raised the threshold to $800 per person per day. That quadrupling coincided almost perfectly with the rise of direct-from-China e-commerce platforms, and the consequences reshaped global retail.

The statutory language is simple: any merchandise imported by one person on one day with a fair retail value in the country of shipment not exceeding $800 may be admitted duty-free and tax-free, without formal customs entry requirements. "One person, one day" is the key limiting principle — a single consumer receiving multiple packages in one day cannot stack de minimis exemptions to cover a combined value exceeding $800.

How De Minimis Works for E-Commerce and Dropshippers

For e-commerce importers and dropshippers, the de minimis exemption historically operated as a structural cost advantage. The mechanics work like this: a seller lists products at $799 or less. A U.S. customer orders. The seller (or their fulfillment partner) ships directly from an overseas warehouse. The package arrives at a U.S. port of entry, the carrier or customs broker files a de minimis claim, CBP releases the package duty-free, and the consumer receives their order with zero import duties factored into the price.

At scale, this model generates an enormous competitive advantage over domestic sellers and importers using formal entry. A U.S. retailer importing the same product in bulk would pay duties (often 7.5–25% under Section 301, or higher under IEEPA), plus the cost of formal entry filing, warehousing, and distribution. The de minimis direct-ship competitor paid none of those costs.

Companies like Temu, Shein, AliExpress, and WISH built multi-billion-dollar revenue models on this arbitrage. By 2024, CBP estimated that roughly 4 million de minimis packages per day were entering the U.S., with the majority originating from China — up from roughly 200 million total annual shipments in 2015. CBP was processing more informal/de minimis entries than formal entries by a factor of 10 to 1.

The 2025 IEEPA Executive Orders: What Changed

The political backlash against de minimis abuse had been building for years. Congress held hearings. The U.S. International Trade Commission published reports on the competitive distortion. Domestic retailers, apparel manufacturers, and industry groups lobbied aggressively. Fentanyl interdiction concerns added a law-enforcement dimension — critics argued that de minimis shipments evaded CBP screening that might intercept drug precursors.

The response came not from Congress but from the executive branch, via the International Emergency Economic Powers Act (IEEPA). Beginning in early 2025, President Trump issued a series of executive orders invoking IEEPA to impose emergency tariffs on Chinese goods. Critically, these orders explicitly suspended the Section 321 de minimis exemption for goods manufactured in or shipped from China, Hong Kong, and Macau.

The key dates and provisions:

• February 4, 2025: Initial IEEPA executive order targeting China imposed 10% tariffs and announced de minimis suspension. Implementation was initially paused due to logistics concerns at USPS.
• March 4, 2025: Revised order increased IEEPA tariffs on China to 20% and reinstated the de minimis suspension, effective immediately for commercial carriers.
• May 2, 2025: Full suspension took effect, including for postal shipments. Goods from China shipped via USPS now face either: (a) applicable duty rates + IEEPA tariffs (up to 145%+), or (b) a flat fee of $75 per postal item (rising to $150 after June 1, 2025).
• Ongoing in 2026: The suspension remains in force. Litigation challenging IEEPA tariff authority (including the de minimis suspension) continues in the Court of International Trade, but no injunctions have been issued that restore de minimis for Chinese goods.

The practical impact was immediate and severe for Chinese-origin e-commerce. Temu and Shein announced price increases of 20–50% for U.S. consumers within weeks. Sellers on AliExpress redirected inventory to EU warehouses. The direct-ship model that had powered a decade of Chinese cross-border e-commerce growth essentially collapsed for the U.S. market overnight.

Which Goods Are Excluded from De Minimis

Even before the 2025 IEEPA orders, certain categories of goods were categorically ineligible for de minimis treatment. Understanding these exclusions is essential for any importer relying on Section 321 for non-Chinese goods.

Antidumping and Countervailing Duty (AD/CVD) Orders

This is the most significant categorical exclusion and the one most importers miss. Any merchandise subject to an antidumping or countervailing duty order is ineligible for the de minimis exemption, regardless of its value. CBP will not release AD/CVD-covered goods duty-free under Section 321 — the importer must file a formal entry and pay applicable AD/CVD rates.

This matters because AD/CVD orders cover a wide range of products: steel and aluminum products, solar panels, furniture, seafood, honey, ceramic tiles, certain chemicals, and hundreds of other commodity categories. An importer receiving a $300 shipment of solar cells from Vietnam (subject to an AD/CVD order) cannot claim de minimis — formal entry and AD/CVD deposit rates apply in full.

Section 201 Safeguard Goods

Goods subject to active Section 201 global safeguard tariff actions are also excluded from de minimis. Section 201 safeguards are broad, country-neutral tariff measures applied across all trading partners when a domestic industry is found to be seriously injured by imports. Historical and current safeguard orders include solar cells and modules, large residential washing machines, and certain steel products.

Controlled Substances and Regulated Goods

Regardless of value, controlled substances (including narcotics and certain pharmaceuticals), alcohol, tobacco products, firearms and ammunition, and goods requiring import licenses or permits cannot clear customs under the informal de minimis process. These goods require formal entry regardless of their declared value.

Country-Specific Suspensions

As of March 2026, China (including Hong Kong and Macau) is the only country subject to a blanket IEEPA-based de minimis suspension. Goods from all other countries — including Vietnam, India, Bangladesh, Cambodia, Mexico, Canada, and EU member states — continue to qualify for de minimis if they meet the $800 threshold and are not subject to AD/CVD orders or other categorical exclusions.

How to Claim Section 321: The Type 86 Entry

Prior to 2019, most de minimis shipments cleared CBP through a simple informal entry process — carriers submitted basic manifest data and CBP released shipments without detailed HTS classification. That changed with the introduction of the Type 86 Entry.

The Type 86 Entry is now the standard CBP mechanism for commercial shipments claiming Section 321 de minimis treatment. Key requirements:

• Filing system: Must be filed through ACE (Automated Commercial Environment), CBP's primary import processing system. Filings are typically submitted by licensed customs brokers or express carriers (FedEx, UPS, DHL have integrated ACE filing into their customs clearance operations).
• Required data elements: 10-digit HTS code, country of origin, manufacturer/supplier identifier (MID), consignee name and address, and declared value. This is substantially more data than the old informal entry required.
• Timing: Type 86 entries can be filed before the goods arrive (pre-arrival filing), which is the norm for express air shipments. CBP typically provides an "arrival" response authorizing release within minutes for low-risk shipments.
• No bond required: Unlike formal consumption entries, Type 86 filings do not require the importer to post a continuous customs bond. This reduces overhead for occasional importers.
• No duty payment: If CBP accepts the de minimis claim, no duty is assessed, no formal entry is created, and the shipment is released. If CBP rejects the de minimis claim (e.g., discovers the goods are AD/CVD-covered), the importer must convert to a formal entry and pay applicable duties.

Postal Shipments and USPS De Minimis

Shipments arriving via international mail (USPS/postal operators) follow a different process. Traditionally, postal de minimis shipments were processed by CBP and USPS under a separate informal mail entry system, without the Type 86 requirement. The 2025 IEEPA orders specifically targeted this postal channel — which was disproportionately used by Chinese e-commerce platforms — as part of the de minimis suspension for China.

For non-Chinese postal shipments, postal de minimis continues to operate, though CBP has expanded its data collection requirements from international postal operators under trade enforcement initiatives.

Strategic Implications for Importers

The de minimis landscape in 2026 is fundamentally different from 2024. Here is how importers should be thinking about it strategically.

1. Source Diversification Is Now a Compliance Imperative

For importers who previously relied on direct-ship Chinese sourcing under de minimis, the suspension is a structural shock — not a temporary headwind. Congressional legislation to permanently close the de minimis loophole for any country with AD/CVD orders (which would cover most Chinese goods regardless of IEEPA) has bipartisan support. The direction of travel is clear: de minimis for Chinese goods is not coming back.

Sellers who have not already begun sourcing from Vietnam, India, Bangladesh, Mexico, or other non-China countries should treat this as urgent. De minimis from these countries continues to function normally, and their lower labor costs can partially offset any quality or lead time differences from Chinese sourcing.

2. Landed Cost Modeling Is Essential

Any importer operating with Chinese goods — whether under formal entry with Section 301 tariffs, IEEPA tariffs, or trying to navigate the post-de-minimis landscape — needs rigorous landed cost modeling. Tariff rates have changed so frequently over 2025–2026 that relying on historical cost structures is a fast path to margin compression or customer pricing errors.

Use our Landed Cost Calculator to model the full import cost including duties, MPF, HMF, freight, and insurance for any shipment. For formal entry scenarios where you may have overpaid duties on goods with incorrect classification or excessive valuation, the Refund Impact Estimator can help you quantify potential recovery through CBP protests or other refund mechanisms.

3. Know Your AD/CVD Exposure

De minimis's AD/CVD exclusion is a trap for importers who don't realize their goods are covered. CBP has been actively ramping up enforcement of AD/CVD evasion through de minimis shipments — including through the Type 86 data collection that now gives CBP the HTS codes and manufacturer IDs needed to identify covered merchandise.

Before relying on de minimis for any product category, verify whether any AD/CVD orders apply using the CBP AD/CVD search tool at CBP.gov and the USITC's EDIS database. Goods subject to AD/CVD orders that are improperly cleared under de minimis remain subject to retroactive duty assessment — CBP can reach back and liquidate those entries with full AD/CVD rates, plus potential penalties.

4. Formal Entry May Now Be Cheaper Per Unit

Counterintuitively, for importers who previously split shipments into small de minimis packages to avoid duties, formal bulk importation with a single consolidated entry may now be more cost-effective. The per-unit cost of customs brokerage fees on a 10,000-unit formal entry is dramatically lower than the administrative burden of processing 10,000 individual Type 86 entries — and with Chinese goods no longer qualifying for de minimis, the duty avoidance rationale no longer exists.

Formal entry also opens access to programs not available under de minimis: duty drawback (recover up to 99% of duties on re-exported goods), first sale valuation (declare the transaction value at the first sale in the supply chain rather than the importer's purchase price), and tariff exclusions on specific HTS subheadings.

5. Watch for Legislative Expansion

Multiple bills in Congress would extend de minimis suspensions beyond China — including to countries like Vietnam, Cambodia, and Bangladesh that have become alternative sourcing destinations. The De Minimis Reciprocity Act and similar proposals would apply the $800 threshold only to countries that offer reciprocal de minimis treatment to U.S. exports. Importers building sourcing strategies around non-China de minimis should monitor this legislative risk and build contingency plans.
