Mexico shipped $9.9 billion of internal combustion engines to U.S. buyers in 2025. USITC reported an effective calculated-duty rate of 9.3%, while measured freight added 0.4% of customs value — an additive 9.7% burden before domestic logistics. The MXN moved 1.7% in favor of the buyer over the last two weeks of the FX window. No country-specific unit value is available for this lane, so it is not ranked by landed unit cost.

• reported duty rate: 9.3%
• freight share: 0.4%
• total uplift: 9.7%

The alternatives, same arithmetic: Canada at 3.0% uplift, South Korea at 13.0% uplift, United Kingdom at 13.0% uplift. At least one listed lane has a lower duty-and-freight burden; total-cost ranking still requires comparable country-specific unit values.

The effective calculated-duty rate is USITC's reported calculated duty divided by the customs value covered by those duty observations for 2025; it is not a verified cash-payment amount or proof of any particular exclusion, quota, or trade-program claim. Freight is the lane's reported import-charges share of customs value. Reference data, not a customs quote.
