Mexico Approves Significant Tariff Increases on Imports from Non-FTA Countries

December 18, 2025

On Dec. 10, 2025, the Mexican Senate approved amendments to the Law on General Import and Export Duties (“Ley de los Impuestos Generales de Importación y Exportación”), introducing substantial tariff increases on 1,463 tariff lines. These amendments are expected to enter into force on Jan. 1, 2026.

Scope of Application

The revised tariffs will apply exclusively to imports originating from countries with which Mexico does not maintain a free trade agreement (FTA). Affected jurisdictions include China, Korea, India, Indonesia, Russia, Thailand, and Turkey. Imports from Mexico’s FTA partners—such as the United States, Canada, Japan, and Singapore—will remain exempt.

Affected Sectors and Tariff Ranges

The measure covers a broad range of sectors, including:

• Textiles and apparel
• Auto parts
• Steel and aluminum
• Plastics
• Toys
• Automobiles and trucks

The increase will include tariffs ranging from 10% to 50%, with automobiles and auto parts subject to the highest rates.

Legislative Intent

According to the Mexican Senate’s official statement, the objective is to “implement concrete actions that allow for a balanced market interaction, in order to avoid economic distortions that could affect the relocation of productive sectors considered strategic for Mexico.”

Implications

The amendments come in the midst of a very dynamic tariff regime in the United States and on the anniversary of the first six-year joint review of the United States-Canada-Mexico Agreement (USMCA).

Mexican importers sourcing from non-FTA countries should anticipate significant cost increases and consider alternative sourcing strategies to prevent supply chain disruptions. Downstream purchasers, including U.S. importers, should assess their upstream exposure to these changes to Mexico’s tariff system.

​​Pennsylvania Superior Court Clarifies Contractors’ Entitlement to Recovery of CASPA Damages Based on Partial Performance of Construction Contracts​

The Pennsylvania Superior Court’s decision in Tedesco Excavating & Paving, Inc. v. FWH Development, LLC significantly expands the scope of recoverable damages under Pennsylvania’s Contractor and Subcontractor Payment Act (CASPA). The court held that contractors may recover overhead, lost profits, interest, costs, and attorneys’ fees even when they have only partially performed a construction contract, particularly where an owner’s anticipatory breach prevents project completion. This ruling provides important guidance for owners, contractors, and subcontractors involved in construction disputes.
