Duty and Freight Add 4.2% to Switchgear, Connectors, and Controls From Mexico

Mexico shipped $15.7 billion of switchgear, connectors, and controls to U.S. buyers in 2025. USITC reported an effective calculated-duty rate of 3.7%, while measured freight added 0.5% of customs value — an additive 4.2% burden before domestic logistics. The MXN moved 6.2% 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: 3.7%
• freight share: 0.5%
• total uplift: 4.2%

The alternatives, same arithmetic: Canada at 4.0% uplift, South Korea at 12.7% uplift, Japan at 12.8% 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.
