US Tariffs on Mexico Stay After Midterms

The United States still charges 10% on Mexican goods that do not qualify for duty-free treatment under the USMCA. The duty took effect on 24 July 2026. Goods covered by the USMCA remain exempt from this new charge. The election result did not alter the tariff rules.

Some products face much higher rates. Steel, aluminum, cars and parts covered by separate Section 232 national-security tariffs pay between 25% and 50%, depending on the product. Those goods are excluded from the new 10% duty, but they are not tariff-free.

The tariffs rely on presidential powers under Section 301 and Section 232. Changing them would require presidential agreement or a new law. The next major trade test is the 2027 USMCA review, with public comments due by 12 January 2027.

The USMCA is the 2020 trade agreement between the United States, Mexico and Canada. Mexico calls it T-MEC. It allows qualifying goods to receive duty-free treatment, which matters because those goods avoid the new 10% Section 301 tariff on Mexican imports.

For example, a Mexican product that meets the USMCA’s qualification requirements can enter the United States without the new 10% charge. An importer must be prepared to show that the goods qualify. The article does not list the pact’s detailed product-specific rules.

The exemption does not remove separate tariffs on covered steel, aluminum, automobiles and auto parts. Those products can still face Section 232 duties of 25% to 50%. The 2027 joint review could affect future trade rules, but its outcome remains open.

Trade between the United States and Mexico is very large. In 2025, the United States imported US$534.3 billion in goods from Mexico and exported US$337.3 billion in goods there. These figures show the scale of the relationship behind the tariff dispute.

The difference is US$197.0 billion. That is calculated by subtracting US$337.3 billion in US exports from US$534.3 billion in imports. The figures cover goods trade, not the broader value of every economic connection between the two countries.

Because so much trade crosses the border, tariff changes can affect importers, producers and buyers. The article says investors should watch the USMCA review and possible steel or car agreements. No final text for such a deal has been published.

A tariff is charged on imported goods. When Mexican products face a 10% duty, US importers must account for that added cost. The article says prices for Mexican-made goods depend on trade rules and executive powers, so the tariff can affect what buyers pay or what businesses absorb.

The impact is sharper for covered steel, aluminum, cars and auto parts. These products are excluded from the new 10% duty but remain subject to separate Section 232 tariffs. Depending on the product, those rates range from 25% to 50%.

The exact effect depends on the product and its trade classification. Importers of qualifying USMCA goods avoid the new 10% charge, while buyers of covered metals and vehicles still face higher separate rates. Mexico is pressing for cuts on steel and cars, but no agreement text is published.

Winning or losing congressional seats does not automatically rewrite tariffs. The article says the 10% duty and separate steel, aluminum and auto duties rest on presidential powers. Those powers let the president impose import taxes under existing trade laws.

Section 301 supports duties against alleged unfair practices. Section 232 supports national-security tariffs, including many duties on metals, vehicles and auto parts. Congress writes trade law, but the article says changing these duties would need a new law or the president’s agreement.

That is why the 3 November 2026 midterm elections did not change the tariff schedule. Congressional control could matter later if lawmakers seek a new law, but the president would need to agree to it. The next scheduled trade process is the 2027 USMCA review.

The main route around the 10% duty is USMCA qualification. Goods that qualify for duty-free treatment under the pact are exempt from the new charge. This gives Mexican producers an incentive to meet the agreement’s requirements when producing and documenting goods for the US market.

The article does not list the detailed product rules for qualification. It does say importers should keep proof of origin ready. That documentation supports the claim that the goods meet the USMCA requirements and therefore qualify for the exemption.

Goods that do not qualify remain subject to the 10% duty. Separate Section 232 tariffs still apply to covered steel, aluminum, cars and auto parts, even when those products are excluded from the new 10% charge. Importers must therefore check both USMCA status and product-specific duties.

A tariff is a charge placed on goods entering a country. It increases the cost of importing those goods. The article’s 10% duty applies to Mexican goods outside the USMCA, while qualifying goods receive an exemption. Tariffs therefore create different costs for goods depending on their trade status.

Governments can use tariffs to influence trade by making targeted imports more expensive. In this case, USTR used Section 301, a trade-law tool aimed at alleged unfair practices. USTR argues that Mexico and Canada do not effectively ban imports made with forced labor, so they received the lowest new rate, 10%.

Tariffs can also be imposed for national-security reasons. Section 232 supports separate duties on steel, aluminum, cars and parts. The article says those rates range from 25% to 50%. The president can impose both types under existing law.
