Section 321 CBP

Section 321 CBP is a provision that allows for the duty-free importation of low-value shipments into the United States. It permits goods valued at $800 or less to enter the country without formal customs entries or payment of duties and taxes, streamlining the import process significantly. This regulation is particularly important for businesses and consumers engaged in cross-border e-commerce.

The Section 321 entry type simplifies customs clearance, but it also involves specific rules and risk assessments by U.S. Customs and Border Protection (CBP). Since 2019, there has been a voluntary test using Entry Type 86, which further accelerates the processing of eligible shipments while accommodating regulatory oversight when needed.

Understanding Section 321 and its related entry types helps importers reduce costs and avoid unnecessary delays. It plays a crucial role in optimizing supply chains for companies shipping low-value goods to the U.S. market.

Understanding Section 321 CBP and Section 321 Entry

Section 321 allows for duty- and tax-free importation of low-value goods into the U.S. This provision includes specific eligibility requirements, a defined entry process, and recent regulatory updates that affect how shipments are handled by Customs and Border Protection (CBP).

Definition and Purpose of Section 321 CBP

Section 321 refers to a U.S. customs provision under 19 U.S.C. 1321 that permits the duty-free entry of imported goods valued at $800 or less per person, per day. It is designed to simplify imports of low-value shipments, reducing customs processing burdens and speeding up clearance.

The purpose is to facilitate trade, especially for e-commerce transactions, by allowing goods to enter without standard customs duties, fees, or formal entry filing. This promotes quicker border clearance and lowers costs for both importers and government.

Eligibility Criteria for Section 321 Entry

To qualify for Section 321 entry, the shipment's total value must not exceed $800. The goods must be imported by a single person on one day, and the shipment should not be intended for resale by a commercial entity.

Certain items, such as those restricted or subject to quotas, do not qualify. Importers must provide accurate product descriptions and value declarations. The shipment must also comply with applicable US laws and CBP regulations.

Overview of the Entry Process

Section 321 entries do not require formal customs entry filings, which means no entry numbers or bonds are necessary. Importers or carriers submit simplified documentation electronically through the Automated Commercial Environment (ACE) system.

This entry type reduces paperwork and processing time, accelerating shipment release. CBP receives advance data including importer information and product details to conduct inspections and manage risk effectively.

Recent Updates and Regulatory Changes

The $800 de minimis threshold was increased from $200 under the Trade Facilitation and Trade Enforcement Act (TFTEA) of 2015. This adjustment expanded the volume of shipments qualifying for duty-free entry.

CBP has also tested new entry types, such as Entry Type 86, to enhance data collection and risk management. These tests aim to integrate e-commerce supply chain data more effectively, improving oversight while maintaining the streamlined clearance process of Section 321.

Practical Considerations for Section 321 Entry

Section 321 entry requires clear understanding of regulatory demands, potential obstacles, and the specific benefits it offers. Managing compliance, addressing common issues, and leveraging advantages are key to optimizing low-value shipments under CBP rules.

Compliance Requirements

Section 321 applies only to shipments valued at $800 or less. Importers must provide accurate HTS codes at the 10-digit level, country of origin, and exact monetary amounts. These details are mandatory under the Entry Type 86 test beginning in 2019.

A valid Automated Commercial Environment (ACE) Manifest submission is required for all Section 321 shipments. This ensures proper risk segmentation by CBP and reduces risk of delays or penalties.

Failure to meet requirements can lead to shipment holds or denial of duty-free treatment. Clear and complete electronic documentation ensures smoother customs clearance.

Common Challenges and Solutions

One common challenge ismisclassification of goods, leading to inaccurate HTS codes or incorrect valuation. Importers should implement strict internal checks and use updated customs databases.

Another issue is documentation errors in ACE filings. Automation and integration of e-commerce platforms with customs software can minimize these errors.

Delays may also arise from non-compliance with packaging or labeling standards. Training staff on CBP guidelines and consulting customs brokers help prevent these problems.

Frequent communication with CBP and monitoring shipment statuses allows quick resolution of issues.

Benefits for E-Commerce and Importers

Section 321 supports expedited customs clearance by eliminating duties on qualifying shipments. This reduces costs and processing time for low-value goods.

For e-commerce businesses, it simplifies fulfilling U.S. orders by removing formal entry processes for many parcels. This creates competitive pricing opportunities and faster delivery windows.

Small importers benefit from reduced paperwork and lower administrative burden. These savings contribute to enhanced cash flow and operational efficiency.

Increased transparency with detailed entry data also improves supply chain visibility and risk management.
