Cross-border e-commerce sellers shipping direct-to-consumer (DTC) parcels into the United States are facing the most significant regulatory shift in a decade. On September 13, 2026, the White House released an extensive fact sheet outlining executive actions and proposed federal rulemakings aimed at curtailing the Section 321 de minimis exemption.
Under Section 321 of the Tariff Act of 1930 (19 U.S.C. 1321), shipments valued at $800 or less per person per day have entered the United States duty-free and with simplified documentation. Over the last ten years, this pathway transformed modern international e-commerce: total de minimis volume entering the U.S. expanded from roughly 140 million packages a year to more than one billion packages annually.
The new administrative package targets this volume directly. Proposed rules from the Department of Commerce and U.S. Customs and Border Protection (CBP) seek to strip de minimis eligibility from any shipment containing goods covered by Section 301, Section 201, or Section 232 trade remedy tariffs. Furthermore, the administration plans to mandate granular 10-digit Harmonized Tariff Schedule (HTS) classification codes for all de minimis shipments and enforce electronic compliance certificate filings for consumer products.
For e-commerce founders, supply chain directors, and cross-border fulfillment teams, this announcement requires immediate operational review. While proposed administrative rules require public comment before becoming final, enforcement on existing declarations is already tightening. Here is what the official announcement specifies, what remains subject to rulemaking, and how shippers must adapt their fulfillment workflows.
Key takeaways
- Tariff Exclusion Proposed: The administration has proposed a Notice of Proposed Rulemaking (NPRM) to make all products subject to Section 301, Section 201, or Section 232 tariffs ineligible for Section 321 de minimis entry.
- Heavy Apparel Exposure: Section 301 tariffs currently cover approximately 40% of all U.S. imports, including roughly 70% of textile and apparel imports from China.
- 10-Digit HTS Requirement: Regulators propose requiring a specific 10-digit Harmonized Tariff Schedule (HTS) classification code and the identity of the person claiming the exemption for all de minimis shipments, ending vague cargo descriptions.
- Mandatory CPSC eFiling: A Consumer Product Safety Commission (CPSC) final rule is advancing to require electronic filing of Certificates of Compliance (CoC) at the time of entry for covered consumer goods.
- Rulemaking Timeline: Executive actions and NPRMs are subject to public comment periods under the Administrative Procedure Act; they are not instantaneous legislative bans, but CBP inspection intensity is rising immediately.
- Fulfillment Mandate: Brands must transition away from generic commercial invoices, establish SKU-level 10-digit HTS mapping in their product databases, and stress-test landed margin scenarios.
What the White House announced: Three regulatory pillars
The September 13 announcement is structured around three coordinated regulatory actions across multiple federal agencies:
1. Eliminating De Minimis for Trade Enforcement Tariffs
Under current rules, low-value parcels entering through informal entry pathways (such as CBP Entry Type 86) can claim Section 321 duty exemption even if the underlying product category is subject to Section 301 tariffs on Chinese goods, Section 232 tariffs on steel and aluminum, or Section 201 safeguard tariffs.
The proposed rule would explicitly bar any shipment containing products subject to these trade remedies from using Section 321. If finalized, affected parcels would have to enter through standard formal or informal consumption entries (such as Entry Type 01 or Entry Type 11), with standard duties and tariffs applied.
2. Mandatory 10-Digit HTSUS Classification and Claimant Identity
CBP has proposed changing the information required for de minimis entry. In place of generic descriptions such as “apparel” or “phone case,” importers would be required to submit:
- The full 10-digit Harmonized Tariff Schedule of the United States (HTSUS) classification code.
- The specific identity of the person claiming the de minimis exemption.
This requirement would effectively eliminate the information gap between containerized cargo and individual e-commerce parcels, granting CBP automated targeting capability across millions of daily shipments.
3. CPSC Electronic Filing of Certificates of Compliance
The Consumer Product Safety Commission is executing a final rule that requires importers of regulated consumer goods—including children’s products, apparel, flammability-sensitive textiles, and certain consumer electronics—to electronically file Certificates of Compliance (CoC) at the time of entry directly with CBP and CPSC systems.
Current framework vs. proposed framework
| Operational Dimension | Current Section 321 / Type 86 Entry | Proposed Regulatory Framework |
|---|---|---|
| Value Threshold | $800 fair retail value per individual per day | Remains statutory $800, but eligibility severely restricted |
| Section 301/201/232 Goods | Generally eligible for duty-free Section 321 clearance | Ineligible: Must enter via formal/informal entry with duties paid |
| Classification Data | Basic product descriptions or 6-digit HTS accepted | Mandatory 10-digit HTSUS classification required |
| Claimant Identification | Often generic consignee or carrier intermediary | Specific identity of entity claiming exemption required |
| Product Safety Filings | Spot-checks and post-clearance audits | Electronic CoC filing at entry with CBP and CPSC systems |
| Clearance Speed | Automated electronic clearance in minutes/hours | Higher audit frequency, secondary inspection holds, potential customs delays |
| Broker Liability | Limited oversight under Section 321 rules | Strict customs broker liability, risk of permit suspension |
Who is affected most?
The proposed rules do not affect all e-commerce categories equally. Shippers should evaluate their exposure across product category, origin country, and commercial structure:
1. Apparel, Fast-Fashion, and Textiles
Apparel represents the single largest category of de minimis parcel volume. Under Section 301 List 3 and List 4A, Chinese-origin apparel and textile products carry tariffs typically ranging from 7.5% to 25%, in addition to base Most-Favored-Nation (MFN) tariff rates that frequently exceed 12% to 32%.
Because Section 301 covers an estimated 70% of textile and apparel imports from China, removing de minimis eligibility would subject a $30 dress or a $40 jacket to combined effective duty rates of 20% to 50% overnight.
2. Consumer Electronics and Accessories
Many consumer electronics and battery-operated goods imported from China fall under Section 301 List 1, List 2, or List 3, carrying 25% tariffs. In addition to potential duty obligations, consumer electronics face heightened scrutiny under CPSC battery safety standards and Federal Communications Commission (FCC) equipment authorization requirements.
3. Direct-to-Consumer Drop-Shipping Brands
Brands shipping single customer orders directly from factories or domestic consolidation hubs in China via air parcel routes will see the largest operational friction. Shippers who rely on freight forwarders to provide blanket HTS codes or simplified manifests will find their logistics chains blocked if individual SKU data is incomplete.
Operational impact for e-commerce sellers and fulfillment teams
Understanding the legal text is only the first step. For operational teams, the real challenge lies in how these rules translate into warehouse workflows, data structures, and cash flow.
1. The 10-Digit HTS Classification Bottleneck
A 6-digit HTS code is international; the 10-digit HTSUS code is specific to the United States and determines the exact duty rate, statistical reporting requirement, and partner government agency (PGA) flag.
Many DTC brands maintain Shopify or WooCommerce catalogs with only SKU names, weights, and selling prices. Under the proposed rule, every SKU in an order manifest must map to an accurate 10-digit code prior to customs submission. An incorrect code can trigger automated customs holds, fines, or seizure for misclassification.
2. Landed Cost Recalculation
If Section 301 goods lose de minimis protection, the cost of duty cannot simply be absorbed by standard e-commerce shipping markups. Brands will face a strategic choice:
- DDP (Delivered Duty Paid): The brand absorbs or collects the duty at checkout, preserving customer delivery experience but requiring accurate duty computation engines on store carts.
- DDU (Delivered Duty Unpaid): The customer receives an unexpected bill from the carrier prior to home delivery—a practice that historically causes customer service spikes and high return-to-sender (RTS) rates.
- Margin Restructuring: Price increases or product bundling to maintain net operating margins.
3. CPSC Testing and Documentation Readiness
The CPSC electronic filing requirement means that having a test report sitting in a factory’s email archive is no longer sufficient. Importers must have verified certificates specifying the applicable safety standards (e.g., 16 CFR 1610 for apparel flammability, 16 CFR 1203 for helmets, or CPSIA lead and phthalate limits for children’s products) linked directly to the customs entry data package.
4. Carrier Holds and Broker Scrutiny
CBP has already suspended several customs brokers from the Entry Type 86 test program for inadequate oversight and repeat non-compliance. As CBP ramps up enforcement in anticipation of final rules, carriers face longer processing times at air express hubs (such as LAX, JFK, ORD, and MIA), resulting in secondary inspection delays for entire consolidated air cargo containers.
What to do next: A 5-step action plan for brands
E-commerce operators should not wait for the final rule to be enacted. Preparing data infrastructure now creates resilience regardless of the eventual implementation timeline:
Step 1: Conduct a SKU-Level 10-Digit HTS Audit
Review your complete active product catalog. Ensure every product has a substantiated 10-digit HTSUS classification based on product composition, material weight, and intended use. Where classification is ambiguous, consult a licensed customs broker or trade attorney.
Step 2: Map Your Trade Remedy Exposure
Cross-reference your 10-digit codes against the U.S. Trade Representative’s Section 301 tariff lists. Determine what percentage of your catalog and sales volume would be impacted if de minimis is revoked for Section 301 goods.
Step 3: Secure Testing Documentation for Regulated SKUs
Contact your manufacturers to collect valid test reports from CPSC-accepted laboratories. Prepare General Certificates of Conformity (GCC) for adult apparel and regulated consumer products, and Children’s Product Certificates (CPC) for any youth items. Ensure these documents match current production batches.
Step 4: Upgrade Warehouse & Order Manifest Data Flows
Work with your fulfillment partner to verify that your shipping integration supports 10-digit HTS, country of origin, manufacturer identification, and product descriptions at the line-item level. Automated manifests must pass clean data to customs brokers without manual spreadsheet manipulation.
Step 5: Evaluate Hybrid Inventory Placement
If your high-volume products fall under heavy Section 301 tariffs, direct air-parcel fulfillment may see eroded unit economics. Brands should evaluate a hybrid fulfillment strategy: importing core, predictable volume via ocean freight under formal entry (paying duties in bulk), while maintaining agile air fulfillment for new launches, testing, and demand surges.
What is still unclear
While the administrative intent is unambiguous, several key aspects remain unresolved as of September 2026:
- Effective Date of the Tariff Exclusion NPRM: Because the exclusion of Section 301/201/232 goods is a proposed rulemaking, CBP and the Department of Commerce must publish the proposed regulatory text in the Federal Register, allow a 30- to 60-day public comment period, review submissions, and draft a final rule. Shippers likely have a preparation window before mandatory implementation.
- Congressional Action vs. Executive Action: The administration has called upon Congress to pass bipartisan legislation that would permanently alter 19 U.S.C. 1321. Executive rules can be challenged in federal courts under the Administrative Procedure Act, whereas statutory changes passed by Congress are significantly harder to challenge.
- De Minimis Threshold Alterations: The proposed executive action does not reduce the statutory $800 threshold for products not subject to Section 301/201/232 tariffs. Non-tariffed products would continue under Section 321, provided 10-digit HTS and identification criteria are satisfied.
Frequently asked questions
Does this announcement mean Section 321 is already cancelled?
No. The exclusion of Section 301, 201, and 232 goods from de minimis is currently a proposed rule (NPRM), not an immediately enforceable law. However, CBP has already intensified audits, enforcement holds, and data requirements under existing Type 86 authorities.
Can I continue shipping products under $800 from China duty-free today?
Yes, current Section 321 rules remain in effect until the proposed rulemaking completes its public notice, comment, and publication cycle. However, parcels must strictly comply with current valuation, intellectual property, and safety rules, and must provide accurate commercial data to avoid broker rejection.
What happens if my products are subject to Section 301 when the final rule takes effect?
Once a final rule takes effect, any parcel containing Section 301 items will be barred from Section 321 entry. It must be cleared through an informal or formal entry process, and applicable base duties plus Section 301 tariffs (e.g., 7.5% or 25%) will be assessed upon entry.
Is the 10-digit HTS code mandatory for every single package?
Under the proposed rules, yes. CBP plans to require the full 10-digit HTSUS code for all de minimis entries to ensure automated risk assessment and compliance verification.
