What Is Section 321 De Minimis?
Section 321 de minimis is a U.S. customs provision that allows low-value shipments to enter the country duty-free and without a formal entry filing. For importers, e-commerce sellers, and logistics teams, understanding exactly how this threshold works — and where it breaks down — is essential to building a compliant import strategy.
Section 321 de minimis: A U.S. customs exemption authorized under 19 USC 1321 that permits one importation per person per day valued at $800 or less to enter the United States free of duty, taxes, and formal entry requirements. CBP processes these shipments as informal entries, dramatically reducing clearance time and cost for qualifying low-value goods.
The $800 threshold has made de minimis the backbone of cross-border e-commerce. In fiscal year 2023, CBP processed over 1 billion de minimis shipments — up from roughly 140 million in 2015, the year before Congress raised the threshold from $200 to $800. That growth has also drawn intense regulatory scrutiny. What was designed to reduce paperwork for small personal purchases now moves hundreds of billions of dollars in merchandise annually, and CBP is actively tightening enforcement.
The Legal Foundation: 19 USC 1321 and the TFTEA
The statutory authority for Section 321 de minimis sits in Title 19 of the U.S. Code. The key references:
- 19 USC 1321 — grants CBP authority to set a low-value threshold below which duties and taxes are not collected
- 19 CFR Part 128 — governs express consignment carrier operations and de minimis processing
- 19 CFR § 10.151–10.153 — details informal entry procedures for low-value merchandise
- Trade Facilitation and Trade Enforcement Act of 2015 (TFTEA) — the legislation that raised the de minimis threshold from $200 to $800, effective March 10, 2016
Before TFTEA, only shipments worth $200 or less qualified for de minimis treatment. The 2016 increase was significant: it brought the U.S. threshold in line with Canada’s and well above the European Union’s €150 limit. It also accelerated the cross-border e-commerce boom — every direct-to-consumer shipment from overseas manufacturers that stayed under $800 suddenly entered the U.S. without duties, taxes, or a formal CBP entry.
For reference, the EU reduced its own de minimis threshold from €22 to €0 in July 2021, effectively eliminating the exemption entirely. The U.S. debate has intensified as a result, with Congress watching European enforcement outcomes closely.
How Section 321 Clearance Works
Step 1: Determine Eligibility
Before a shipment can move under Section 321, three basic conditions must be met:
- The shipment’s fair retail value in the country of shipment does not exceed $800
- It represents one importation per person per day — the same person cannot receive two separate Section 321 shipments from the same or different origins on the same day and combine the values
- The merchandise is not excluded from de minimis treatment (see exclusions below)
Step 2: Transmit Entry Data Through ACE
Qualifying shipments are filed as Type 86 entries through CBP’s Automated Commercial Environment (ACE) portal. The Type 86 entry was introduced in 2019 to give CBP better data visibility into de minimis shipments — previously, many flowed through even less formal channels.
Required data elements for a Type 86 entry include:
- Shipper name and address
- Consignee name and address
- Description of merchandise (including HTS number at 10-digit level)
- Country of origin
- Declared value
- Carrier tracking number
Step 3: CBP Automated Risk Screening
ACE runs the shipment through automated targeting systems. CBP’s National Targeting Center cross-references shipment data against enforcement priorities — counterfeit goods, prohibited items, antidumping/countervailing duty (AD/CVD) orders, and other flags.
Step 4: Release or Hold
If no flags are triggered, CBP issues an automated release and the package moves to delivery. Most qualifying Section 321 shipments clear in hours, not days. If CBP issues an Intensive Exam (EXAM) or Hold, the carrier must present the merchandise at the port of entry for physical inspection before release.
Step 5: Delivery
Once released, the shipment moves through the carrier’s normal domestic distribution network. No duty, MPF (Merchandise Processing Fee), or HMF (Harbor Maintenance Fee) is collected.
What Section 321 Does NOT Cover
This is where most compliance errors happen. The following categories are explicitly excluded from de minimis treatment, regardless of value:
| Category | Reason for Exclusion | Governing Authority |
|---|---|---|
| Antidumping / countervailing duty goods | AD/CVD orders must be collected | 19 USC 1671–1677 |
| Quota merchandise | Quota fills must be tracked formally | 19 CFR Part 132 |
| Certain agricultural products | USDA/APHIS oversight required | 7 CFR various |
| Textiles requiring entry and visa | Quota and licensing compliance | 19 CFR Part 12 |
| FDA-regulated items (food, drugs, devices) | Prior notice, labeling, and safety review | 21 CFR various |
| Alcoholic beverages | TTB licensing and state law | 27 CFR various |
| Firearms and ammunition | ATF permits required | 27 CFR Part 447 |
| Trademarked goods that violate IPR | Counterfeit seizure authority | 19 USC 1526 |
If your product falls into any of these categories, it must enter through a formal entry (CBP Form 3461 or 7501) regardless of value. A licensed customs broker can advise whether your specific commodity is affected.
Real-World Scenarios: Section 321 in Practice
Scenario 1: Direct-to-Consumer E-Commerce (Qualifies)
A U.S. consumer orders a $65 phone case directly from a manufacturer in Shenzhen. The shipment is valued at $65, ships via express carrier, and contains no restricted materials. The express carrier files a Type 86 entry in ACE. CBP’s targeting system finds no flags. The package clears automatically and arrives in two days with zero duties assessed. This is the textbook Section 321 use case.
Scenario 2: Apparel Shipment with Quota Flag (Does Not Qualify)
An e-commerce reseller imports 50 units of polyester-cotton blend shirts from Bangladesh, each valued at $14, with a total shipment value of $700. Even though the shipment is under $800, certain textiles require formal entry and quota reconciliation. CBP flags the shipment during ACE screening, issues a hold, and requires a formal entry. The importer owes duties plus the MPF minimum of $31.67.
Scenario 3: Order Splitting (Violation)
A U.S. retailer places a $5,000 order with a Chinese supplier. The supplier ships the order as seven separate packages to the same consignee address on the same day, each declared at $714, attempting to keep each under the $800 threshold. CBP’s targeting system identifies the common shipper, consignee, purchase order number, and same-day delivery pattern. CBP consolidates the shipments, assesses full duties on the entire order, and opens a penalty case under 19 USC 1592 for attempted duty evasion. Fines can reach four times the unpaid duties for gross negligence.
Scenario 4: Low-Value Pharmaceutical Sample (Does Not Qualify)
A pharmaceutical distributor receives a $200 product sample from a European lab. Despite being well under $800, the item is regulated by FDA as a drug. It requires an FDA Prior Notice filing and a formal CBP entry. Value alone does not determine eligibility.
Common Mistakes and Misconceptions
Mistake 1: Assuming $800 means $800 per shipment, always. The limit applies per person per day, not per package or per transaction. Two shipments valued at $500 each, delivered to the same consignee on the same day, total $1,000 and do not qualify.
Mistake 2: Using the sale price instead of fair retail value. CBP values de minimis shipments at the fair retail value in the country of origin — not the sale price, discounted price, or promotional price listed by the seller. Declaring a $300 product as $50 because of a coupon is customs fraud.
Mistake 3: Believing Section 321 covers all product types under $800. Value is only one test. Product type is an independent test. A $50 bottle of wine, a $200 handgun accessory, or a $150 dietary supplement with undeclared drug ingredients all fail the product test regardless of value.
Mistake 4: Relying on de minimis for B2B import strategies. Section 321 is designed for individual consumer shipments. Importers using it systematically to avoid duties on commercial quantities — even in low-unit batches — face growing scrutiny. CBP’s Commercial Targeting Division specifically monitors high-frequency low-value importers.
Mistake 5: Ignoring proposed rule changes. In May 2024, CBP published a notice of proposed rulemaking that would exclude goods subject to Section 301 tariffs (most goods from China) from de minimis eligibility entirely. If finalized, this would eliminate de minimis treatment for a significant share of current shipment volume. Monitor the CBP website and Federal Register for final rule status.
Section 321 vs. Formal Entry vs. Informal Entry
Understanding where Section 321 sits relative to other entry types helps importers structure their operations correctly.
| Entry Type | Value Range | Duties | MPF | Broker Required | Typical Clearance |
|---|---|---|---|---|---|
| Section 321 (Type 86) | ≤ $800 | None | None | No (but recommended) | Hours |
| Informal Entry (Type 11) | $801–$2,500 | Yes | $31.67 minimum | No (self-file allowed) | 1–2 days |
| Formal Consumption Entry (Type 01) | > $2,500 | Yes | 0.3464% of value | Strongly recommended | 1–5 days |
| Formal Entry (Textiles/AD/CVD) | Any value | Yes | Yes | Yes | Varies |
Importers handling consistent volumes above $800 per shipment should work with a licensed customs broker to ensure classification accuracy and regulatory compliance. You can browse brokers by U.S. port of entry to find specialists who handle high-volume express cargo at your specific entry point.
