De Minimis Thresholds: US $800 vs Mexico $117 — What Importers Must Know

What Is a De Minimis Threshold?

The de minimis threshold is the maximum value of an imported shipment that can enter a country without paying customs duties and taxes, and with simplified customs processing. Below this threshold, the cost of collecting duties exceeds the revenue generated, so governments waive them to facilitate trade. However, de minimis thresholds vary dramatically between countries, and recent policy changes — particularly in the US — are reshaping how this provision works for cross-border e-commerce.

United States: The $800 De Minimis Threshold

The US has the highest de minimis threshold in the world at $800 per person per day, established under Section 321 of the Tariff Act (raised from $200 in 2016). This means any import shipment valued at $800 or less can enter the US without paying duties, taxes (no federal sales tax), or formal customs entry requirements. This provision has been a cornerstone of the cross-border e-commerce boom, enabling platforms like Amazon, Temu, and Shein to ship millions of low-value packages directly from overseas to US consumers.

Mexico: The $117 USD De Minimis Threshold

Mexico's de minimis threshold is approximately $117 USD (equivalent to 50 USD for duties and $117 for taxes under different regulations, depending on interpretation). In practice, most shipments entering Mexico above $50 USD are subject to standard customs procedures including a pedimento filed by a customs broker, payment of IGI (import duty), and 16% IVA. Mexico's lower threshold means that cross-border e-commerce shipments are subject to customs processing at much lower values than in the US.

Side-by-Side Comparison

• US threshold: $800 USD per shipment per person per day. Mexico threshold: ~$50-117 USD depending on the regulation applied.
• US duties below threshold: none. Mexico duties below threshold: may still apply depending on the product and entry type.
• US customs filing below threshold: no formal entry required (Section 321). Mexico: simplified entry possible for postal/courier, but customs broker may still be needed.
• US taxes below threshold: no federal taxes (no federal sales tax). Mexico: IVA (16%) may still apply on e-commerce purchases.
• US enforcement trend: tightening, especially for China-origin goods. Mexico enforcement trend: stable, with e-commerce taxation through platform withholding.

Impact on E-Commerce and Cross-Border Sellers

For e-commerce sellers shipping to the US, the $800 de minimis threshold has been a massive advantage — but one that is rapidly eroding for China-origin goods. Sellers should prepare for a future where HTS classification is required even for low-value shipments, and where Section 301 tariffs apply regardless of shipment value. For Mexico, the low de minimis threshold means that virtually all commercial e-commerce shipments require formal customs processing, making compliance costs a significant consideration for small-value shipments.

De minimis thresholds are one of the most dynamic areas of trade policy in 2026. The US is moving toward stricter enforcement and potential elimination of de minimis for certain origins, while Mexico continues to apply its lower threshold consistently. Importers and e-commerce sellers who understand these thresholds — and prepare for changes — will have a competitive advantage.
