A 1938 administrative shortcut grew into a 1.36-billion-parcel-a-year e-commerce highway. In eighteen months, three executive orders shut it down. Here is the timeline, the duty math, and what comes next.
TL;DR
1938 → 2016
“De minimis” is Latin for “about trifles.” Congress wrote it into U.S. customs law in 1938, as Section 321 of the Tariff Act of 1930, for a deeply unsexy reason: collecting duty on a one-dollar trinket cost the Treasury more than the duty was worth.[1][2] The original ceiling was $1 — about $17 in 2015 dollars when the Congressional Research Service ran the math.[1]
The threshold drifted up slowly for fifty-five years. Congress raised it to $5 in 1990, then to $200 in 1993, this time changing the statute from a discretionary ceiling to a mandatory floor: Treasury was now required to grant duty-free treatment to qualifying low-value shipments, not merely permitted to.[1] CRS notes that the 1993 increase, unlike the 1978 one, was “well in excess of inflation” — an inflation-adjusted figure would have landed closer to $10.[1]
Then came the bigger move. In February 2016, the Trade Facilitation and Trade Enforcement Act (TFTEA) raised the de minimis ceiling from $200 to $800 per person per day.[3] The legislative history framed it as a modernization win for “businesses, U.S. consumers, and the U.S. economic growth.”[3] What happened next was not what Congress imagined.
“Over the last 10 years, the number of shipments entering the United States claiming the de minimis administrative exemption increased by more than 600 percent.”
1938
Section 321 enters U.S. customs law
Congress adds a $1 administrative-convenience exemption to the Tariff Act of 1930. The Treasury, then collecting most federal revenue from customs, doesn't want to chase pennies.[1]
1978
Adjusted upward, roughly with inflation
Routine recalibration in the era before e-commerce. Trade volumes are still measured in containers, not parcels.[2]
1990 → 1993
$5, then $200 — and ceiling becomes floor
Congress requires Treasury to grant the exemption rather than merely permitting it. The threshold jumps far past inflation; the political logic is trade facilitation, not revenue.[1]
Feb 2016
TFTEA raises de minimis to $800
The Trade Facilitation and Trade Enforcement Act (Pub. L. 114-125) lifts the threshold to $800 per person per day. The change takes effect in March 2016.[3]
FY2015 → FY2024
Volume explodes from 134M to 1.36B parcels
CBP processes roughly 4 million de minimis parcels per day by the end of FY2024, with an estimated retail value of $64.6B.[4][1]
The $54B channel
When the threshold moved to $800, two things lined up: cross-border air freight got cheap, and Chinese platforms got ambitious. By 2023, de minimis imports from China alone had grown to $54.5 billion — up from $9.2 billion in 2016.[10] Roughly 60 percent of all de minimis shipments to the United States originated in China.[10]
A House Select Committee on the CCP estimated in 2023 that Shein and Temu alone accounted for ~30 percent of total U.S. de minimis volume, shipping somewhere on the order of 600,000 packages a day, parcel by parcel, direct to consumer.[10][13] They were not abusing the rule. They were building businesses on it.
The economics were brutally simple. A $25 dress shipped from a Foshan warehouse to a customer in Phoenix paid no duty, no MPF, no broker fee — an Entry Type 86 manifested through CBP's ACE system in seconds, with limited Partner Government Agency review.[4] A U.S. apparel importer bringing the same dress in by container paid the Most Favored Nation rate of ~16.5%, plus a 7.5% Section 301 surcharge from List 4A, plus MPF and HMF, plus brokerage and warehouse handling.[19][20]

There was also a national-security thread woven through the policy debate. The same parcel pipe that delivered $5 phone chargers also moved synthetic-opioid precursor chemicals — fentanyl analogs in 50-gram pouches that fell well below the formal-entry data-collection bar.[7] By 2024, both parties on Capitol Hill were drafting de minimis bills. The question was no longer whether the loophole would be narrowed, but how violently.
Feb 2025 → Aug 2025
The first executive order — signed February 1, 2025, effective February 4 — paired new IEEPA tariffs on China, Canada, and Mexico with an immediate suspension of de minimis for all three. Within 48 hours it was clear that CBP could not technically process millions of new dutiable parcels per day. The China de minimis suspension was paused within a week, pending a Commerce Department certification that “adequate systems” were in place to assess and collect the duties.[11]
That certification arrived in late April. Executive Order 14256 (April 2, 2025) re-implemented the China and Hong Kong de minimis closure on a hard deadline: 12:01 a.m. EDT on May 2, 2025. Every commercial parcel from China and Hong Kong now required a formal or informal entry. Postal items from those origins moved to a flat per-piece structure of either 30% ad valorem or $25 per item — rising to $50 per item on June 1.[7][8]
Three months later, the administration generalized. EO 14324, signed July 30, 2025, suspended duty-free de minimis treatment for all countries beginning 12:01 a.m. EDT on August 29, 2025.[6][5] CBP's ACE system began rejecting all Entry Type 86 transmissions; importers had to file under Type 11 (informal) or Type 01 (formal) and pay the applicable duties.[5] Postal parcels moved to a per-item flat duty of $80, $160, or $200 — depending on the country's reciprocal tariff bracket — for a transition window through February 28, 2026.[6]
Feb 1, 2025
First IEEPA EO suspends de minimis for China, Canada, Mexico
Effective Feb 4, 2025. Within days CBP cannot keep up; the China de minimis suspension is paused. Canada and Mexico tariffs are deferred to March 4 after diplomatic talks.[11]
Apr 2, 2025
EO 14256 re-implements the China/Hong Kong closure
White House cites the synthetic-opioid emergency and ties the action to IEEPA. Effective date set for May 2, 2025; postal flat rate of $25/parcel introduced.[7]
May 2, 2025
China and Hong Kong de minimis closes — for real
12:01 a.m. EDT. Commercial low-value parcels from China and Hong Kong now require formal or informal entry. Postal duty rises to $50/item on June 1.[8]
Jul 30, 2025
EO 14324 — de minimis suspended for ALL countries
Signed by President Trump; effective Aug 29, 2025. Justified as “closing a catastrophic loophole” for tariff evasion and unsafe imports.[6]
Aug 12, 2025
ACE moves from warning to hard enforcement
CBP's Automated Commercial Environment ends the “warning-only” period and begins rejecting non-compliant Type 86 entries.[5]
Aug 29, 2025
Global de minimis suspension goes live
Every country, every commercial low-value parcel, dutiable. Postal flat-rate window of $80–$200 per item opens, set to expire Feb 28, 2026.[5]
Dec 2025
CBP announces $1B in collected duties
$1B+ assessed on 246M low-value shipments since May. Daily parcel volume reported down from ~4M to ~1M; seizures of unsafe goods up 82% versus pre-closure baseline.[9]
Feb 20, 2026
Supreme Court strikes down IEEPA tariffs
6–3 ruling led by Chief Justice Roberts holds IEEPA does not authorize the underlying reciprocal tariffs. The same day, the President issues a new EO re-anchoring the de minimis suspension on alternative statutory authority. De minimis stays closed.[23][24][25]
Landed cost, line by line
The cost of a low-value commercial parcel under the new regime stacks in a specific order. There is the Most Favored Nation (MFN) duty by HTS chapter — the “normal” rate. On top of that, where applicable, sit Section 301 duties on Chinese goods (the legacy List 1–4A schedule, which List 4A holds at 7.5% for most apparel and consumer electronics), Section 232 duties on steel and aluminum content, and the IEEPA reciprocal tariffs that survived past 2026.[20][19] CBP then assesses the Merchandise Processing Fee (MPF) and, on ocean shipments only, the Harbor Maintenance Fee (HMF). And the broker — whether the carrier or a separate licensed customs broker — will charge a fee for filing the entry.
| Cost line | Rate / amount | Notes |
|---|---|---|
| MFN duty (apparel, ch. 61–62) | 0%–32%, typically 14–17% | By HTS subheading. May 2025 average for U.S. apparel imports: 23.8%. |
| MFN duty (footwear, ch. 64) | 0%–48%, often compound | Cheap athletic shoes hit 48%; many lines have % + ¢/pair components. |
| MFN duty (jewelry, ch. 71) | 5–13.5% | Lower for precious-metal articles, higher for imitation jewelry. |
| MFN duty (beauty, ch. 33) | Generally 0% | Cosmetics, fragrances, and most skincare are duty-free at MFN. |
| Section 301 (List 4A) | +7.5% | Most consumer apparel and electronics from China. |
| Section 301 (List 1–3) | +25% | Industrial inputs, electronics components. |
| MPF (formal entry) | 0.3464% ad valorem | Min $33.58 / max $651.50 per entry as of Oct 1, 2025. |
| MPF (informal) | $2.69 / $8.06 / $12.09 | Flat fee depending on filing channel. |
| HMF (ocean only) | 0.125% ad valorem | No min, no max. Air, truck, rail exempt. |
| Broker fee | ~$25–$150 per entry | Carrier-disbursed clearance often $25–$50; specialty broker higher. |

Consider an HTS 6204.43 woven polyester dress with a $50 declared value, shipped commercially from Guangzhou to a U.S. consumer.
| Era | Duty + fees | Total to consumer |
|---|---|---|
| Pre-May 2, 2025 (de minimis) | $0 — Type 86, duty-free | $50.00 |
| Post-May 2, 2025 (China only) | MFN 16% = $8.00 Section 301 List 4A 7.5% = $3.75 IEEPA reciprocal ~30% = $15.00 Broker (carrier) ~$25 | ≈ $101.75 |
| Post-Aug 29, 2025 (worldwide) | Same stack applies regardless of origin; non-China origins skip Section 301 but still pay MFN + reciprocal + broker | ≈ $80–$110, by origin |
Illustrative; actual duties depend on the eight-digit HTS code, country-of-origin determination, and carrier surcharges. Figures derived from rates in this article's table and Sheng Lu apparel-tariff dataset.
For consumers, the end of de minimis can result in “quite a big price increase.” Most people using the exemption were on a budget — some will simply buy less.
The Fajgelbaum-Khandelwal NBER paper backs that intuition with hard data: de minimis imports are a meaningful, regressive transfer to lower-income U.S. households, and removing the exemption reduces consumer surplus disproportionately at the bottom of the income distribution.[18] Whether the offsetting duty revenue is worth it is, in Lovely's words, “something we will probably never really know.”[17]
Temu, Shein, AliExpress
CBP reported that daily import volume fell from ~4 million parcels to ~1 million in the weeks after the China and Hong Kong carve-out — a ~75% reduction concentrated almost entirely in the China-direct channel.[9] The Universal Postal Union saw inbound U.S. postal volume from China collapse by ~54%.[12] The three platforms most exposed to the change responded in three very different ways.
| Platform | Pre-closure model | Post-closure response |
|---|---|---|
| Temu | China-direct DTC; consolidated air freight; Type 86 entry; sub-$50 average ticket. | Suspended direct-from-China shipping for U.S. orders; pivoted to a U.S. semi-managed marketplace, onboarding domestic third-party sellers and inventorying goods in U.S. fulfillment centers ahead of order.[14][15] |
| Shein | China-direct DTC for fast fashion; high gross margin absorbed shipping; ~600K parcels/day combined with Temu. | Maintained China-direct shipments at a higher landed cost; accelerated manufacturing diversification to Turkey, Mexico, Brazil; explored Vietnam.[14][15] |
| AliExpress | Marketplace model; mix of China-direct DTC and AliExpress “Choice” pre-positioned U.S. inventory. | Expanded U.S.-warehoused “Choice” inventory; encouraged sellers to use bonded fulfillment partners; raised platform-level price-floor adjustments.[16] |
The lesson visible across all three responses is the same. When a per-parcel customs hit becomes mandatory, the only way to preserve a sub-$50 retail price point is to absorb the duty across many units at once — i.e., to consolidate at the border and pay duty once, on a container, not 1,000 times on 1,000 parcels.
FTZs, bonded warehouses, ACH
No legal mechanism reproduces the old de minimis economics. But several long-standing customs programs reduce the per-parcel friction or defer the duty hit until a sale actually occurs. Each has different rules and different fits.
| Program | What it does | What it does NOT do |
|---|---|---|
| Foreign-Trade Zone (FTZ) | Designated U.S. site treated as outside customs territory. Duty is paid only when goods enter U.S. commerce. Goods can be processed, repackaged, kitted; weekly entry consolidates many shipments under one MPF. | Does not avoid duty on goods sold domestically. Setup is non-trivial; most brands access an FTZ via an activated 3PL site rather than building their own. |
| Bonded warehouse (Class 9 fulfillment) | Storage of imported goods duty-unpaid for up to 5 years. Duty assessed on withdrawal; useful when re-export is likely or duty timing matters for cash flow. | 5-year cap; cannot perform manufacturing or significant processing without specific bond class. Re-exported portion avoids U.S. duty entirely. |
| ACH brokerage / periodic monthly statement | Lets a broker pay accumulated duty in one ACH debit per month, smoothing cash flow. | Does not reduce duty owed; purely a payment-mechanism efficiency. |
| Postal flat-rate ($80/$160/$200) | Available through Feb 28, 2026 for international postal items; flat duty per parcel by country's reciprocal-tariff bracket. | Window expires; not available to commercial express channels (FedEx, UPS, DHL parcel). |
| USMCA pre-clearance | Goods of qualifying U.S. / Mexico / Canada origin under the USMCA rules of origin enter at preferential duty rates. | Does not restore de minimis. Origin claims require certification and audit-ready records. |
The new arithmetic
Run the numbers on a brand selling 1,000 units of a $25 SKU into the U.S. each month, sourced from China. Under the old de minimis regime, shipping each unit individually as a Type 86 parcel was the obvious choice — each parcel was duty-free, formal entry was unnecessary, and air-freight transit times were measured in days.
Under the post-August 2025 regime, the same 1,000 individual parcels each owe the full duty stack. Even if a brand uses a customs broker who batches the entries, the per-parcel MPF, brokerage, and handling overhead crushes margin. Consolidating those 1,000 units into a single ocean container — one MPF (capped at $651.50), one HMF, one brokerage event — is dramatically cheaper, even before factoring in faster domestic delivery.
| Cost line | 1,000 individual parcels | 1 consolidated entry, 1,000 units |
|---|---|---|
| MFN duty + reciprocal | Same per-unit ad valorem | Same per-unit ad valorem |
| MPF | $2.69–$12.09 × 1,000 = $2,690–$12,090 | 0.3464% capped at $651.50 (single entry) |
| HMF (ocean) | Air-shipped — N/A | 0.125% on entered value |
| Broker fee | $25 × 1,000 = $25,000 (carrier-disbursed) | $150 per entry (single) |
| Per-unit overhead | ≈ $27 in fees + brokerage | ≈ $1 in fees + brokerage |
| Transit | 5–10 days air, parcel-by-parcel | 20–30 days ocean, then 1–2 day domestic |
Illustrative monthly comparison; figures derived from rates cited above. Formal-entry brokerage cost is one-time per shipment; per-parcel carrier-disbursed clearance accumulates.
The math collapses into a simple rule: the more units you sell, the more punitive per-parcel customs becomes, and the more attractive a U.S.-domiciled inventory model is. For brands above ~50 orders per day, the break-even on switching from cross-border to U.S.-3PL fulfillment generally arrives inside the first month of post-de-minimis volume.
Outlook
The Supreme Court's February 20, 2026 decision in Learning Resources, Inc. v. Trump invalidated the IEEPA tariffs that had supplied roughly half of the post-2025 duty stack on Chinese imports.[23] Importers may eventually recover IEEPA-paid amounts via protests and the CIT, though the procedural path is still being tested.[25]
The de minimis suspension itself, however, was not vacated. The administration issued a successor executive order the same day re-anchoring it on alternative authority, and the Court's ruling did not directly address Section 321.[24][25] Industry counsel are watching Axle of Dearborn v. Department of Commerce, which directly attacks the de minimis suspension on administrative-law grounds.[25]
Three things are likely to remain true through the rest of 2026 regardless of how the litigation resolves:
“Since the de minimis loophole was closed for goods from China and Hong Kong, seizures of unsafe and non-compliant low-value goods have increased by 82 percent.”
