De Minimis Rules: What Every Importer Needs to Know

De minimis is a U.S. customs provision that allows low-value shipments — currently those at or below $800 — to enter the country duty-free with minimal paperwork. For e-commerce sellers, small importers, and cross-border supply chains, understanding de minimis is not optional: the rules are changing fast, and the consequences of misuse are serious.

What De Minimis Actually Means in U.S. Customs

De minimis (from the Latin de minimis non curat lex — “the law does not concern itself with trifles”) is the threshold below which U.S. Customs and Border Protection does not require a formal entry filing or collect duties on imported merchandise.

In the United States, this threshold is codified at 19 USC 1321, commonly referred to as the Section 321 provision. The current threshold of $800 per person per day was set by the Trade Facilitation and Trade Enforcement Act of 2015, which increased it from the previous $200 level — a 300% jump that fundamentally reshaped cross-border e-commerce.

De minimis entry: A customs clearance pathway under 19 USC 1321 that permits goods valued at $800 or less, imported by a single person on a single day, to enter the United States free of duties, taxes, and formal entry requirements.

According to CBP data, the agency processed approximately 1.1 billion de minimis shipments in fiscal year 2023 — a volume that strains inspection capacity and has triggered significant legislative and executive scrutiny. CBP Commissioner testimony to Congress in 2023 noted that de minimis entries now account for roughly 93% of all cargo entries processed by CBP, up from under 40% a decade ago.

How De Minimis Clearance Works: Step by Step

The Section 321 clearance process looks simple from the outside — your package arrives and clears without customs paperwork. Behind the scenes, it involves a structured data pipeline between carriers, CBP’s automated systems, and partner government agencies.

Step 1: Advance Electronic Data Submission

Before a shipment reaches a U.S. port, the carrier, express consignment operator (ECO), or postal service must submit advance electronic data (AED) to CBP. This includes the shipper name and address, consignee name and address, declared value, description of goods, and country of origin.

Step 2: Automated Risk Screening

CBP’s Automated Targeting System (ATS) processes the incoming data against risk criteria, watchlists, and historical patterns. Shipments flagged as high-risk — regardless of value — are pulled for examination. This step is where CBP catches counterfeit goods, fentanyl precursors, and AD/CVD violations that have been deliberately undervalued.

Step 3: Entry Type Determination

Based on ATS scoring, CBP assigns the shipment one of three treatment paths:

• Section 321 release — cleared automatically, no duty, no formal entry
• Informal entry — required for goods valued $800–$2,500 in most categories
• Formal entry (Type 01) — required for goods over $2,500 or any regulated/AD/CVD merchandise

Step 4: Physical Examination (When Selected)

Selected shipments are routed to a CBP examination area. Officers may open packages, verify declared values, check for trademark violations, and confirm country of origin. Mismatches between declared and actual content can trigger 19 USC 1592 penalties for false statements.

Step 5: Delivery or Hold

Cleared shipments proceed to the consignee. Held shipments generate a CBP Form 28 (Request for Information) or CBP Form 29 (Notice of Action). Importers have rights to respond, but shipments can be seized, returned, or subjected to full duties if violations are confirmed.

The Legal Framework: Regulations and Exclusions

The de minimis provision sits in a specific legal structure that many importers underestimate. Knowing the statutes and regulatory exclusions prevents costly surprises.

Primary statute: 19 USC 1321 — authorizes the Treasury Secretary (delegated to CBP) to prescribe conditions under which low-value goods are exempt from formal entry and duty collection.

CBP implementing regulations: 19 CFR Part 10, Subpart B — sets out the administrative procedures for claiming informal and de minimis entries, including carrier responsibilities and data requirements.

Key exclusions from de minimis:

The antidumping and countervailing duty exclusion is particularly important. Even a $5 shipment of a product covered by an AD/CVD order — searchable at enforcement.trade.gov/adcvd — does not qualify for de minimis treatment and must be entered formally with full duties declared.

What the Latest De Minimis News Actually Means for Importers

This is the section most importers need right now. The de minimis provision has faced sustained legislative and executive pressure since 2022, and the changes in 2024–2025 represent the most significant restructuring since the $800 threshold was set.

Key developments:

Executive Order on Chinese-Origin Goods (February 2025): The White House issued an executive order effectively eliminating de minimis treatment for goods originating from China and Hong Kong. CBP began enforcing this change on May 2, 2025, after a brief administrative pause. This directly impacts platforms like Shein, Temu, and the thousands of small sellers who ship direct-to-consumer from Chinese warehouses.

STOP Act and related bills: Congress has introduced multiple bills targeting de minimis abuse, primarily focused on fentanyl precursor chemicals and counterfeit goods flowing through low-value shipments. The STOP Act would require carriers to submit fuller data — including seller identity and full product descriptions — for all international mail shipments, closing a data gap that CBP has cited as a major enforcement weakness.

CBP data requirements expansion: Beginning in 2024, CBP expanded mandatory AED fields for de minimis shipments, requiring additional seller identification data. Non-compliant shipments from non-compliant carriers face increased examination rates.

Why this matters to your operation: If you source any inventory from Chinese manufacturers — whether direct-to-consumer or through a fulfillment model — your cost structure may have changed materially. Goods that previously entered at zero duty now potentially face tariff rates between 7.5% and 145% depending on the HTS classification and applicable Section 301 tariff list. Verify current HTS-level duty rates at hts.usitc.gov before building margin assumptions.

Real-World Scenarios: Who Is Affected and How

Understanding the rule changes in the abstract is less useful than seeing how they play out in actual import scenarios.

Scenario 1 — The direct-to-consumer Alibaba seller A U.S.-based e-commerce seller sources products from Alibaba suppliers who ship individual orders directly from Shenzhen to American consumers. Each order is valued at $35. Before May 2025, every shipment entered free under Section 321. After the executive order, each shipment from China now requires formal entry or postal duty collection. The landed cost per order increases, and the seller needs a customs broker or freight forwarder to handle volume if consolidating, or the postal operator handles duty collection for individual packages.

Scenario 2 — The supplement importer A wellness brand imports herbal supplement capsules valued at $600 per shipment. Even though the value is below $800, FDA regulates dietary supplements under 21 CFR Part 111. These shipments require FDA prior notice and cannot use Section 321. The importer must file a formal entry and comply with FDA import requirements. Many first-time supplement importers learn this the hard way — work with a broker who specializes in food and pharmaceutical imports from the start.

Scenario 3 — The order-splitting pattern A retailer receives 500 units of product in one shipment from a foreign supplier. To avoid formal entry and duties, someone instructs the supplier to split the shipment into smaller consignments under $800. CBP’s ATS flags this pattern — same shipper, same consignee, consecutive days, same product — as a potential 19 USC 1592 violation. The entire shipment may be detained, and penalties can far exceed the avoided duties.

Scenario 4 — The legitimate small importer A furniture designer imports one-of-a-kind handmade items from artisan workshops in Mexico, each priced at $500–$750. These qualify legitimately for de minimis entry. The importer should still ensure the items are not subject to USMCA chapter rules that require origin documentation, and that they don’t fall under any AD/CVD orders affecting furniture. A quick check on CBP Binding Rulings for similar products confirms proper treatment.

Common Mistakes and Misconceptions About De Minimis

Mistake 1: Assuming de minimis means no CBP review Every de minimis shipment is screened electronically. CBP examines a percentage of packages physically. The provision removes the formal entry and duty obligation — it does not create an inspection-free corridor.

Mistake 2: Splitting shipments to stay under $800 This is one of the most commonly cited enforcement targets in CBP trade enforcement actions. Artificially dividing a single commercial shipment across multiple Section 321 entries to avoid duties constitutes a false statement under 19 USC 1592. Penalties start at 20% of unpaid duties for negligence and reach four times the unpaid duties for fraud.

Mistake 3: Assuming all products from any country still qualify The country-of-origin exclusions — particularly for Chinese-origin goods effective 2025 — mean that a product’s value being below $800 is no longer sufficient. Origin matters as much as value.

Mistake 4: Not accounting for partner government agency (PGA) requirements CBP is not the only agency with jurisdiction over imported goods. FDA, USDA, EPA, FCC, and Consumer Product Safety Commission all have independent authority to hold or refuse shipments. De minimis status does not override PGA requirements.

Mistake 5: Using de minimis for commercial merchandise repeatedly The statute specifies de minimis applies to goods imported by “one person” on “one day.” CBP interprets repeated commercial importations through Section 321 as circumventing formal trade requirements. High-volume commercial importers who route everything through de minimis face audit risk.

Tools and Resources for De Minimis Compliance

Staying current requires using the right primary sources. Here are the tools practitioners rely on.

If your business model depends on de minimis entries — or if recent changes have made you realize you can no longer depend on them — working with a licensed customs broker is the most reliable way to restructure your import process correctly. You can browse brokers by U.S. port of entry to find one near your primary receiving location, or search all CBP-licensed customs brokers by specialty.

A broker can also help you understand what your 10 core customs broker responsibilities actually cover — including classification, valuation, and duty liability advice — before you commit to a supply chain structure.

If you’re running a fulfillment operation that spans customs brokerage and warehousing, understanding how 3PL with customs clearance works can help you evaluate whether a combined provider makes more operational sense than separate broker and 3PL relationships.
