Duty and Freight Add 3.3% to Transformers and Power Supplies From Mexico

Mexico shipped $6.2 billion of transformers and power supplies to U.S. buyers in 2025. USITC reported an effective calculated-duty rate of 2.9%, while measured freight added 0.4% of customs value — an additive 3.3% burden before domestic logistics. The MXN moved 5.2% 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: 2.9%
• freight share: 0.4%
• total uplift: 3.3%

The alternatives, same arithmetic: Canada at 3.9% uplift, Spain at 9.1% uplift, South Korea at 9.3% uplift. No listed alternative has a lower duty-and-freight burden, but that alone does not establish the lowest landed unit cost.

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.
