The $800 duty-free threshold that let 4 million packages slip into the U.S. every day without customs scrutiny is gone — permanently. If you import low-value goods, source components under $800, or run any direct-to-consumer model, your compliance costs just went up and your margin just went down. Here's exactly what happened, what it means, and what to do before July 24.
Four million packages a day. That's how many shipments entered the United States under the Section 321 de minimis exemption in 2025 — roughly 1.36 billion packages annually, representing an estimated $61 billion in goods that paid zero duties, underwent minimal screening, and required no HTS classification whatsoever.
On June 24, 2026, CBP published two interim final rules that ended that era permanently. Not temporarily. Not for specific countries. For everyone, through every mode of entry, effective immediately.
The rules — published at 91 FR 37789 and 91 FR 37801 — don't just suspend a threshold. They fundamentally restructure how low-value goods enter the United States. If you're a customs broker handling e-commerce clients, an importer sourcing samples and components, or a freight forwarder processing consolidated shipments, your operational playbook just got rewritten.
The History: How a Minor Administrative Shortcut Became a $61 Billion Loophole
Section 321 of the Tariff Act of 1930 was never meant to be a trade policy. It was a bureaucratic shortcut — a way to avoid spending $20 in government processing costs to collect $3 in duty on a tourist's souvenir.
The threshold started at $1 in 1930. Congress raised it to $200 in 1993, then to $800 in 2016 under the Trade Facilitation and Trade Enforcement Act. That $800 level was supposed to reduce CBP's administrative burden while facilitating legitimate low-value trade.
What nobody anticipated was the explosion of Chinese e-commerce platforms. Between 2016 and 2024, de minimis shipment volume surged from 220 million packages to over 1.36 billion — a 518% increase in eight years. By 2024, 92% of all cargo entries into the United States were de minimis shipments. Shein and Temu alone accounted for roughly 600,000 packages daily.
The exemption had become, in CBP Commissioner Rodney Scott's words, a system where "billions of low-value shipments entered the United States without sufficient information" — no HTS codes, no duty assessment, no country-of-origin verification, and critically, no way to enforce Section 301, Section 232, or forced labor restrictions on goods that simply bypassed the entry system entirely.
What the Two Rules Actually Do
CBP issued two separate interim final rules on June 24, 2026, each targeting a different mode of entry. Understanding the distinction matters because compliance timelines differ.
Rule 1: Non-Postal Shipments (91 FR 37789)
This rule covers everything arriving by ocean, air, truck, rail, or express consignment — essentially all commercial cargo except international mail. It amends 19 CFR 10.151(b) to indefinitely suspend duty-free treatment for merchandise valued at $800 or less.
Effective date: June 24, 2026 (immediate)
What it means operationally:
- Every shipment under $800 now requires either a formal entry (Entry Type 01) or informal entry (Entry Type 11)
- Full HTS classification is mandatory — no more shipping without tariff codes
- All applicable duties, taxes, and Merchandise Processing Fee (MPF) apply
- Country-of-origin must be declared and is subject to all existing trade remedy programs (Section 301, Section 232, AD/CVD)
Rule 2: International Postal Shipments (91 FR 37801)
This rule covers goods arriving through the international postal network (USPS international mail). It suspends the de minimis exemption under 19 CFR 145.31 and creates an entirely new postal informal entry process.
Key dates:
- De minimis suspension: June 24, 2026 (immediate)
- New postal informal entry process: July 24, 2026
- PGA data requirements and Chapter 98/99 compliance: October 22, 2026
The New Entry Type 13
CBP simultaneously published a companion notice (91 FR 38007) announcing a voluntary electronic test program — Entry Type 13 — specifically for mail entries. This is CBP's attempt to create a streamlined electronic process for the massive volume of postal shipments that now require formal processing.
Who Gets Hit Hardest
Not every importer feels this equally. Here's how the pain distributes:
| Importer Type | Impact Level | Primary Concern |
|---|---|---|
| E-commerce platforms (Shein, Temu model) | Critical | Entire business model relied on duty-free entry |
| Direct-to-consumer brands shipping from overseas | High | Per-unit costs increase 15-40% on low-value items |
| Importers sourcing samples/prototypes | Medium | Administrative burden; every $50 sample needs entry |
| Customs brokers with e-commerce clients | High | Massive volume increase with thin margins per entry |
| Traditional importers (full container loads) | Low | Already filing formal entries; minimal change |
| Freight forwarders handling consolidated cargo | Medium | Must verify no shipment in consolidation qualifies for informal treatment |
For customs brokers, the math is brutal. If you're processing entries for e-commerce clients at $10-15 per informal entry, and your client was previously shipping 10,000 packages/month duty-free with no entry required, you just inherited 10,000 new entries per month — each requiring HTS classification, duty calculation, and CBP filing.
The Duty Math: What $800 Shipments Actually Cost Now
Let's make this concrete. Consider a shipment of consumer electronics accessories from China, valued at $75:
| Cost Component | Before (De Minimis) | After (Informal Entry) |
|---|---|---|
| Duties (Section 301: 25%) | $0 | $18.75 |
| Merchandise Processing Fee | $0 | $2.00 (minimum) |
| Harbor Maintenance Fee (if ocean) | $0 | $0.19 |
| Broker/filing fee | $0 | $10-15 |
| HTS classification cost | $0 | Included or $5+ |
| Total additional cost | $0 | $30.94 - $35.94 |
| Effective duty rate on $75 item | 0% | 41-48% |
For a $75 item, the all-in landed cost increase is 41-48%. For items under $25, the fixed costs (MPF minimum, broker fees) can push effective rates above 100%.
This is why the de minimis exemption mattered so much to low-value e-commerce — it wasn't just about the duty rate. It was about avoiding the entire entry infrastructure.
The Legal Basis: Why CBP Bypassed Normal Rulemaking
Both rules were issued as interim final rules — meaning they took effect immediately without the standard notice-and-comment period required by the Administrative Procedure Act. CBP invoked two exceptions:
- Foreign affairs exception (5 U.S.C. § 553(a)(1)) — arguing the rules implement the president's trade policy authority
- Good cause exception (5 U.S.C. § 553(b)(B)) — arguing delay would undermine enforcement
CBP is accepting public comments through July 24, 2026 on docket numbers:
- USCBP-2026-0760 (non-postal shipments)
- USCBP-2026-0761 (postal/mail shipments)
Comments submitted by July 24 will be considered in the final rulemaking, but don't expect the suspension itself to be reversed. The comment period is about implementation details — bonding requirements, Entry Type 13 procedures, and transition timelines.
What About the Legal Challenges?
The de minimis suspension arrives in a broader context of tariff litigation. The Supreme Court struck down IEEPA tariffs in Learning Resources, Inc. v. Trump (146 S.Ct. 628, 2026). The Court of International Trade subsequently ruled Section 122 tariffs unlawful in Oregon v. United States (May 7, 2026).
But the de minimis suspension is on much firmer legal ground. Unlike IEEPA or Section 122 tariffs, which tested novel interpretations of presidential authority, 19 U.S.C. § 1321 explicitly grants the Secretary of the Treasury (delegated to CBP) discretionary authority to set administrative exemptions. The $800 threshold was always a regulatory choice, not a statutory mandate. CBP can raise it, lower it, or eliminate it entirely through normal rulemaking.
Legal challenges are possible — particularly on the APA procedural shortcuts — but importers should not plan around the suspension being overturned.
What to Do Now: 7 Action Steps Before July 24
-
Audit your de minimis exposure — Identify every SKU, sample order, or shipment stream that previously entered under Section 321. Quantify volume, value, and country of origin. This is your cost-impact baseline.
-
Classify everything — Every item that previously shipped without an HTS code now needs one. Start with your highest-volume SKUs. If you're handling hundreds of product types, prioritize by landed cost impact (items from Section 301 countries get hit hardest).
-
Establish entry procedures — Decide whether shipments will use formal entry (Type 01) or informal entry (Type 11). Informal entry applies to shipments valued under $2,500 but still requires HTS classification and duty payment.
-
Review bonding requirements — Informal entries require a continuous bond or single-transaction bond. If your e-commerce clients don't have bonds in place, they need them now. CBP requires bonds from every importer of record filing entries.
-
Evaluate Entry Type 13 — If you handle postal shipments, monitor CBP's voluntary test program for the new electronic informal entry process. Early participation may provide operational advantages as the system scales.
-
Restructure pricing models — For direct-to-consumer importers: your delivered cost just increased significantly. Update pricing, communicate to customers, or absorb the hit — but decide now, not after margins erode for months.
-
Submit comments by July 24 — If the implementation timeline, bonding requirements, or Entry Type 13 procedures create specific operational problems for your business, submit comments to dockets USCBP-2026-0760 and USCBP-2026-0761. Industry input on implementation details may influence the final rule.
What's Coming Next
The de minimis kill is one piece of a larger enforcement overhaul. Watch for:
- July 24, 2026: New postal informal entry process takes effect. Comment period closes on both interim final rules.
- October 22, 2026: Full PGA (Partner Government Agency) data requirements and Chapter 98/99 compliance obligations kick in for postal entries.
- Entry Type 13 rollout: CBP's electronic test program will expand. Brokers who integrate early will have a processing advantage as volume migrates from duty-free to dutiable entries.
- Enhanced enforcement: With every low-value shipment now generating entry data, CBP will have visibility it never had before. Expect targeting algorithms to flag inconsistencies in declared values, origins, and classifications across high-volume shippers.
The days of 4 million packages entering the U.S. daily with no customs scrutiny are over. What replaces it is still being built — but the direction is clear: more data, more duties, and more enforcement on every single shipment regardless of value.
The New Reality
The de minimis exemption was always a policy choice, not a trade right. For a decade it served legitimate purposes — reducing friction for travelers, samples, and low-value commerce. But when 92% of all U.S. cargo entries are flowing through a channel designed for souvenirs, the system has been outgrown.
For customs brokers, this is simultaneously a challenge and an opportunity. The volume of entries requiring professional handling just increased by orders of magnitude. For importers, it's a cost reset that demands immediate attention to classification accuracy and supply chain structure.
TariffLens helps trade teams classify at scale — the kind of capability that matters when thousands of SKUs suddenly need HTS codes for the first time.
