What Is the U.S. De Minimis Threshold and Why Has It Been Suspended?

For years, one rule shaped how many low-value shipments entered the United States: The U.S. de minimis threshold.

For nearly a decade, Section 321 of the Tariff Act of 1930 (19 U.S.C. §1321) allowed low-value shipments to enter the United States with simplified customs treatment and, in most cases, no duties.

That all suddenly changed.

Effective Aug 29, 2025, the U.S. government suspended duty-free de minimis treatment for shipments valued at $800 or less. As a result, goods that previously entered under Section 321 without duty assessment are now subject to applicable tariffs, taxes, and fees.

For ecommerce sellers, cross-border shippers, and U.S. importers, this marks one of the most significant customs policy shifts in years.

This post explains what the de minimis threshold was, how it worked, and why the U.S. suspended it.

What Was Section 321 (The U.S. De Minimis Rule)?

Section 321, commonly referred to as the “de minimis” rule, allowed shipments valued at $800 or less to enter the United States without formal entry and, in most cases, without paying duties.

The $800 threshold was established in 2016 under the Trade Facilitation and Trade Enforcement Act (TFTEA), raising the prior $200 limit and dramatically expanding duty-free parcel imports into the U.S.

Under Section 321, qualifying shipments generally benefited from:

• Simplified clearance procedures.
• Reduced data and documentation requirements.
• No duty assessment on most goods.
• Faster release through CBP.
  

These benefits fueled the rapid growth of cross-border ecommerce, particularly high-volume parcel imports. CBP has processed well over one billion de minimis shipments annually in recent years, underscoring how central Section 321 became to U.S. trade flows.

Why De Minimis Mattered So Much

De minimis shaped importing because it affected:

• Whether the duties applied
• How much paperwork customs required
• How quickly shipments cleared
• Total landed cost expectations

Many businesses built logistics and ecommerce models around this rule.

What Changed on Aug 29, 2025?

As of Aug 29, 2025, shipments valued at $800 or less no longer automatically receive duty-free treatment under Section 321.

While the statutory $800 valuation threshold remains part of U.S. law, the duty-free benefit associated with de minimis treatment has been suspended. U.S. Customs and Border Protection confirmed that goods valued at $800 or less will no longer receive de minimis duty-free entry and will instead be subject to applicable duties, taxes, and fees. 

This means:

• L.ow-value shipments may now be subject to applicable tariffs, including IEEPA and other trade remedy duties.
• Importers must file entries through CBP’s Automated Commercial Environment (ACE) using the appropriate entry type (formal or informal).
• Customs classification and valuation are now subject to standard enforcement scrutiny, regardless of shipment value.

In short, low value no longer means low regulatory impact.‍

How Postal Shipments Are Impacted

The suspension also applies to international postal imports.

Under updated CBP guidance:

• Postal shipments previously entering duty-free are now subject to tariffs under the International Emergency Economic Powers Act (IEEPA) and other applicable duties.
  
• Duties may be assessed either:
  
  • On an ad valorem basis (based on the HTS classification and declared value), or
  • Under a temporary specific per-item duty method ranging from $80 to $200, depending on the country-of-origin tariff exposure.
    

CBP has indicated that the specific per-item method is temporary. Beginning Feb 28, 2026, postal shipments must transition to the ad valorem method based on proper HTS classification and valuation.

Why the U.S. Suspended De Minimis Treatment

The suspension reflects escalating concerns within the U.S. government regarding:

• Tariff and trade-remedy evasion through high-volume, low-value shipments.
• Misclassification and systematic undervaluation.
• Enforcement challenges associated with mass parcel imports.
• The rapid expansion of cross-border ecommerce platforms.

The White House and enforcement agencies have cited risks of deception, evasion, and scale-driven compliance gaps as key drivers of this policy shift.

What the Suspension Means for Importers

With duty-free de minimis treatment suspended, importers should expect:

• Increased duty exposure, even on small parcel shipments.
• Greater scrutiny of HTS classification and valuation.
• More frequent use of informal or formal entries filed through ACE.
• Higher likelihood of broker involvement.
• Potential customs bond requirements for recurring importers.

Many ecommerce importers who previously relied on Section 321 may now need a continuous customs bond, particularly if formal entries are required.

Importers without a licensed customs broker relationship may encounter delays, increased inspection risk, or unexpected costs.

Why Classification Matters More Than Ever

Under duty-free de minimis, classification errors often carried a limited financial impact. That buffer is gone.

Today:

• HTS classification directly determines tariff exposure.
• Incorrect classification can trigger immediate duty liability and enforcement penalties.
• Incomplete product descriptions increase inspection risk.
• Valuation errors create compliance exposure.

Errors that once went unnoticed under simplified treatment can now generate real financial and regulatory consequences.

Compliance Risk Has Increased

The suspension of duty-free de minimis shifts parcel imports into a higher-accountability framework. Importers should prepare for:

• Retroactive duty assessments are if misclassified.
• More frequent CBP holds or examinations.
• Expanded data requirements at the time of entry.
• Reduced predictability in landed cost modelling.

Low-value shipments now carry compliance responsibilities similar to higher-value commercial imports.

How Importers Should Prepare

To reduce disruption, importers should:

• Confirm correct HTS classification for all products.
• Validate declared values and supporting documentation.
• Assess whether a customs bond is required.
• Establish a relationship with a licensed U.S. customs broker.
• Model duty impact into pricing and landed cost calculations.

Proactive compliance planning will reduce delays and cost surprises at the border.

The Most Important Takeaway

The U.S. de minimis threshold once simplified the treatment of low-value imports. The suspension changes the landscape. Importers need to feel confident in their compliance efforts. Adapting to stronger classification and documentation requirements ensures smoother shipments and reduces surprises.

In short, low-value no longer means low-friction, and importers should plan for duties, documentation, and compliance upfront.
