What Is Section 321?
Understanding Section 321
Section 321 refers to 19 USC 1321, a provision of United States customs law that established a “de minimis” threshold for imported goods. Under this provision, shipments valued below a specified threshold could historically enter the US with simplified customs procedures and without payment of duties and taxes.
The term “de minimis” means “about minimal things”—reflecting the original intent to reduce administrative burden for low-value shipments. The de minimis threshold was set at $800 for qualifying shipments.
Section 321 became significant for cross-border ecommerce, allowing individual consumer orders to clear customs with reduced complexity. For comprehensive guidance on current cross-border requirements, explore our cross-border compliance services.
Key Section 321 Concepts
- 19 USC 1321 – The legal statute
- De minimis – Minimum threshold concept
- $800 – Historical value threshold

- Type 86 entry – E-commerce entry type
Section 321 De Minimis Exemption
Historical Context
Note: The following describes the historical operation of Section 321 prior to its suspension in August 2025.
The Section 321 de minimis exemption allowed shipments valued at $800 or less to enter the United States without formal customs entry and without payment of duties or taxes. This threshold, raised from $200 in 2016, was among the highest in the world.
The exemption was widely used in cross-border ecommerce, particularly for direct-to-consumer shipments. Brands shipping individual orders from international locations could leverage Section 321 to offer customers duty-free delivery on qualifying purchases.
Common use cases included cross-border fulfillment models where inventory was held outside the US and shipped directly to US consumers, marketplace sellers shipping from international warehouses, and dropshipping operations with overseas suppliers.
Section 321 Entry Types (Historical)
- Informal Entry – Traditional simplified procedure
- Type 86 Entry – E-commerce focused (post-2019)
- Manifest clearance – Carrier-level processing
- Low-value shipment processing
- Express consignment procedures
- Bonded facility release options
Section 321 CBP & Customs Entries
Regulatory Framework
Section 321 CBP procedures were administered by US Customs and Border Protection. CBP established various entry types and processing mechanisms to handle qualifying low-value shipments.
Section 321 customs entry procedures evolved over time, including the introduction of Type 86 entries in 2019 specifically designed for high-volume e-commerce shipments. These entries required specific data elements for security and compliance purposes.

Current Status: Section 321 Suspension
Critical Update
Section 321 de minimis benefits are suspended as of August 2025.
This means shipments that previously qualified for duty-free entry under Section 321 are now subject to standard customs entry procedures, duties, and taxes.
Is Section 321 still in effect? No. The de minimis exemption has been suspended, meaning the $800 threshold no longer applies for duty and tax relief. All commercial shipments entering the United States are now subject to formal entry requirements.
What does “suspended” mean operationally? Businesses can no longer rely on Section 321 for simplified customs clearance or duty-free treatment. Shipments previously cleared under informal or Type 86 entries now require formal entry and are subject to applicable tariffs and taxes.
Risks of outdated assumptions: Businesses relying on Section 321 in their supply chain planning, landed cost calculations, or fulfillment models must update their strategies. Continued reliance on suspended provisions can result in shipment delays, unexpected costs, and compliance violations.
Impact on Ecommerce, Fulfillment & Shipping
Business Impact
The Section 321 suspension significantly affects cross-border ecommerce operations. Brands that built fulfillment models around duty-free individual shipments must now account for duties and taxes in their landed cost calculations.
Section 321 shipments that previously cleared quickly with minimal paperwork now face standard customs processing times and documentation requirements. This impacts delivery timelines and operational complexity.
For businesses shipping internationally, our international shipping services include updated guidance on customs requirements and transit time expectations in the post-Section 321 environment.
Areas Affected

Section 321, China & Mexico: Risk & Scrutiny
Enforcement Context
Section 321 attracted significant regulatory attention due to concerns about high-volume shipments from specific origin countries. China and Mexico became focal points for enforcement scrutiny given the volume of e-commerce shipments utilizing the de minimis exemption.
Regulatory concerns included circumvention of trade remedies, product safety compliance, intellectual property enforcement, and accurate customs valuation. These concerns contributed to the policy changes that ultimately led to Section 321’s suspension.
For businesses with supply chains involving these origin countries, working with experienced compliance partners is essential. Our high-volume seller solutions include compliance guidance for navigating increased scrutiny and enforcement priorities.
