The End of Duty-Free: How CBP's De Minimis Kill Reshapes Every Import Under $800

On June 24, 2026, CBP flipped the switch on 1.36 billion annual shipments. The $800 de minimis exemption — the loophole that let 92% of all cargo entries skip customs duties entirely — is gone. If you import anything valued under $800, your cost structure just changed overnight. Here's how to adapt before you get hit with penalties you didn't see coming.

Four million packages a day. That's how many shipments entered the United States duty-free under Section 321 of the Tariff Act of 1930 before CBP published two Interim Final Rules on June 24, 2026. Those 4 million daily packages — worth a collective $61 billion annually — now owe duties, taxes, and fees on every single entry.

This isn't a proposed rule. It's not a comment period before action. CBP used the interim final rule mechanism, meaning the suspension took effect the day it was published. The comment period (deadline: July 24, 2026) is running concurrently with enforcement. You're already subject to this rule.

For customs brokers, this is the single largest operational shift since ACE modernization. For importers who relied on de minimis for sample shipments, replacement parts, or low-value commercial goods, the math just changed dramatically.

What Section 321 Was — and Why It Died

Section 321 of the Tariff Act of 1930 allowed shipments valued at $800 or less to enter the United States free of duties and taxes without a formal customs entry. It was designed as an administrative convenience — the cost of processing a $15 entry wasn't worth the $0.50 in duty CBP would collect.

That made sense in 1930. It made sense in 2015, when 140 million packages a year used the exemption. It stopped making sense when the volume hit 1.36 billion packages in fiscal year 2024 — a 900% increase in under a decade.

The explosion was driven almost entirely by Chinese e-commerce platforms. Shein and Temu alone accounted for roughly 600,000 packages per day, shipping individual consumer orders directly from Chinese warehouses to U.S. doorsteps with zero customs scrutiny. Over 60% of all de minimis shipments originated from China before the initial country-specific suspension in May 2025.

The administration's stated concerns went beyond lost revenue:

• Duty evasion: Goods subject to Section 301 tariffs (up to 100% on Chinese imports) were entering duty-free by staying under $800
• Safety gaps: De minimis shipments faced minimal inspection, creating vectors for counterfeit goods, fentanyl precursors, and goods produced with forced labor
• Competitive distortion: Domestic retailers and U.S.-warehousing importers paid full duties while direct-from-China shipments paid nothing

The Two Interim Final Rules: What Changed on June 24

CBP issued two separate rules that together eliminate de minimis treatment across every mode of entry:

Rule 1: Non-Postal Modes (Effective June 24, 2026)

This rule suspends de minimis for all shipments arriving via air cargo, ocean freight, truck, and rail — everything except international mail. Key provisions:

• All shipments valued at $800 or less must now use formal or informal entry procedures
• Full duties, taxes, and fees apply based on HTS classification
• Standard record-keeping and entry documentation requirements apply
• No delayed compliance date — this took effect immediately

Rule 2: International Postal Network (Effective June 24, 2026; Compliance October 22, 2026)

This rule handles packages arriving through USPS and foreign postal services:

• De minimis exemption suspended for postal shipments effective June 24
• New postal informal entry process for merchandise valued at $2,500 or less (classifiable in HTSUS Chapters 1-97)
• New bonding requirements for informal mail entries
• New data submission requirements for postal shipments
• Delayed compliance date of October 22, 2026 for the new postal informal entry process

Who Gets Hit Hardest

This isn't just a Temu and Shein problem. The de minimis exemption was used across every industry:

E-commerce sellers and marketplaces — Third-party sellers importing inventory in small batches now face entry costs on every shipment. A $50 product from Vietnam that arrived duty-free now owes its Column 1 rate (often 5-20%) plus the Merchandise Processing Fee (MPF) of 0.3464% (minimum $31.67 for formal entries).

Manufacturers importing parts and samples — That $200 replacement component from your German supplier? Previously duty-free. Now it requires a classified entry with the correct HTS code, country of origin determination, and applicable duty payment.

Customs brokers — Your potential client base just expanded by 4 million entries per day. But so did your operational burden. Every one of those entries needs classification, valuation, and proper documentation.

Small businesses — A small importer bringing in $500 in artisan goods from Mexico now faces a formal entry process that costs more in brokerage fees than the duties owed.

The Cost Math: What $800-and-Under Shipments Now Owe

Here's what a previously duty-free $500 shipment now looks like:

That last line is the kicker. For many low-value shipments, the cost of compliance — hiring a broker, filing the entry, maintaining records — exceeds the duty itself. CBP acknowledged this in the preamble but concluded that enforcement integrity outweighed administrative convenience.

The July 24 Comment Deadline: What to File

CBP is accepting public comments on both interim final rules until July 24, 2026. This is your opportunity to shape the final version. Key areas where industry input may influence the outcome:

1. Threshold alternatives — Should CBP establish a lower de minimis threshold (e.g., $100 or $250) rather than full elimination?
2. Informal entry simplification — Are the new data requirements for postal entries workable at scale?
3. Small business impact — Can CBP create a streamlined process for low-risk, low-value commercial shipments?
4. Bonding requirements — Are the new bond amounts proportionate for informal mail entries?

Comments should be submitted via regulations.gov, referencing the specific docket numbers for each rule.

What to Do Right Now: Action Steps for Importers

1. Audit every sub-$800 import stream — Identify all shipments that previously entered under Section 321. Map each to the correct HTS code and calculate the duty exposure. Many importers don't even know which of their shipments used de minimis because their logistics providers handled it automatically.

2. Establish or expand your broker relationship — If you were self-clearing de minimis shipments, you now need either a customs broker or the internal expertise to file entries. Start conversations now — brokers are seeing a surge in onboarding requests.

3. Consolidate shipments where possible — Multiple $200 shipments that each require separate entries (and separate brokerage fees) may be cheaper combined into a single $1,200 formal entry. The per-entry compliance cost makes consolidation more economical than ever.

4. Verify your HTS classifications — Shipments that never needed classification now need correct 10-digit HTS codes. Misclassification on a $50 shipment carries the same penalty risk as misclassification on a $50,000 shipment. With the June 3 customs enforcement executive order imposing a minimum 50% penalty floor, getting classifications wrong is more expensive than ever.

5. Update your ACE portal access — Ensure your importer of record number, bonds, and ACE account are current. If you've only ever imported above de minimis thresholds, your existing setup should work. If you're new to formal entries, start the ACE registration process immediately.

6. Review your supply chain for postal vs. non-postal routing — Postal shipments have until October 22 for full compliance with the new informal entry process. Non-postal shipments have no grace period. If you're routing low-value goods through postal channels, you have slightly more runway — but not much.

What's Coming Next

The de minimis suspension is part of a broader enforcement escalation. Watch for:

• October 22, 2026: Full compliance required for the new postal informal entry process, including bonding and data requirements
• September 1, 2026: The customs enforcement executive order mandates streamlined seizure and forfeiture processes for noncompliant shipments
• November 30, 2026: New importer-of-record eligibility rules, registry cleanups, and minimum bonding mandates take effect

The pattern is clear: CBP is systematically closing every low-friction import pathway and replacing it with full documentation, classification, and duty payment requirements. The de minimis suspension is the biggest single piece, but it's not the last.

The Broker Opportunity — and Responsibility

For customs brokers, this is simultaneously the largest market expansion in decades and a significant operational challenge. Four million daily shipments that never needed a broker now potentially do. But those shipments are low-value, high-volume, and often lack the documentation that formal entries require.

The brokers who thrive will be those who build scalable, technology-driven processes for high-volume, low-value entries — not those who try to handle each $200 shipment with the same manual workflow they use for a $200,000 container.

TariffLens is built for exactly this kind of classification at scale — turning thousands of product descriptions into accurate HTS codes without manual research on each one.
