Mexico US Tariffs: Ebrard Presses T-MEC Review in Washington

Mexico · Trade

As the T-MEC review enters a critical phase, Mexico’s top trade official is lobbying for tariff relief. Here’s what it means for investors and regional trade.

The Mexico US tariffs fight is heating up as Economy Secretary Marcelo Ebrard heads to Washington and the G20 to press Mexico’s case on autos and steel during the ongoing T-MEC review. The stakes are huge — Mexico now supplies nearly half of all US auto parts and over 17% of US goods imports, so any tariff change ripples across the North American economy.

Ebrard’s Persistent Strategy in Washington

Marcelo Ebrard, Mexico’s Secretary of Economy, is leading a diplomatic offensive described as ‘persistent, perseverant, patient.’ His goal: to influence US decisions on tariffs affecting autos, steel, and aluminum.

As he put it on August 13, 2026, his obligation is to be close to where decisions are made to promote Mexico’s viewpoints. This steady posture underscores a long-game approach rather than confrontational brinkmanship.

The strategy is backed fully by President Claudia Sheinbaum’s administration, coordinating every move. Ebrard’s team has submitted detailed studies and arguments to US officials, aiming to change minds with data, not threats.

Mexico is also leaning on its impressive trade numbers to make the case that tighter integration benefits all three countries. US goods imports from Mexico reached US$298.157 billion in Jan-Jun 2026, up 13% year-on-year, making Mexico the source of 17.1% of all US goods imports.

Confirmed Meetings and G20 economy ministers meeting

Ebrard will attend the G20 economy ministers and central bank governors meeting in North Carolina, starting August 31, 2026, at the invitation of US Commerce Secretary Howard Lutnick. The event focuses on innovation and technology, but trade talks will likely dominate side meetings.

Additionally, the fourth round of bilateral Mexico-US talks under the T-MEC review is confirmed for early September in Washington. The agenda covers rules of origin, semiconductors, North American supply chains, agriculture, labor, vehicles, steel, aluminum, and economic security.

These meetings come on top of a busy schedule that includes a USTR ruling expected in August 2026 under a Section 301 investigation. Ebrard expects that decision, which is separate from Section 232 tariffs, but could trigger new trade remedies.

No new formal Section 232 ruling has been issued in August 2026, signaling that the US may be waiting for the outcome of the bilateral talks. This breathing room gives Mexico a window to press for concessions before any final decisions.

What Mexico Wants: Lower Auto and Steel Tariffs

Mexico is formally requesting that the US refrain from imposing additional new tariffs while the T-MEC review is ongoing. The current 25% Section 232 tariff on cars made in Mexico that don’t fully meet treaty rules is a major sticking point.

Per the Wall Street Journal (reported by Reuters), Mexico has proposed applying US tariffs only to vehicles non-North-American content, which would lower the effective rate to roughly 5-10% for compliant vehicles — a proposal, not an agreement. Mexico also wants the 50% tariff on Mexican steel reduced or made more flexible, with aluminum also under Section 232 scrutiny.

Ebrard confirmed that Mexico’s delegation has submitted studies and arguments to justify lowering these tariffs. The T-MEC remains in force until 2036, but the July 1, 2026 review milestone has opened the door for renegotiation.

The auto tariff relief is particularly critical because Mexico supplies a record share of US auto parts — a record 44.73% of US auto-parts imports in Jan-Jun 2026. A lower tariff would keep those supply chains competitive, while a higher one could force automakers to rethink their North American footprint.

For steel, the 50% tariff is a heavy burden, as many Mexican manufacturers rely on imported steel that now faces double duties. Reducing that rate would ease input costs across multiple industries, from construction to machinery.

Why This Matters for Investors and Expats

For investors and expats in Latin America, the outcome of these trade talks could reshape cross-border supply chains and affect companies with operations in Mexico. If the effective auto tariff falls toward roughly 5-10% under the proposal, production costs could ease, boosting Mexico’s manufacturing competitiveness and potentially increasing foreign direct investment.

A reduction in steel tariffs would also ease input costs for Mexican manufacturers, improving margins and export growth. On the other hand, prolonged uncertainty could deter investment, so the pace of these negotiations is key.

Mexico’s overall trade stance is strong: in 2025, Mexico exported US$534.3 billion to the US, with an effective tariff rate of 3.66% on total exports. About 85% of Mexican exports pay no effective duty; on the taxable ~15% slice (autos, auto parts, steel), the average tariff is 23.84%.

If Ebrard succeeds in cutting those top-line tariffs, the effective rate could drop sharply, making Mexican exports even more attractive. That would likely lure more foreign capital into Mexico’s manufacturing bases, from the Bajío region to the northern border states.

Why US Automakers Are Watching Closely

Mexico’s trade weight gives it real leverage in negotiations, as US automakers and parts suppliers depend heavily on Mexican supply chains. Detroit automakers fear a treaty revamp could cost them billions, according to Reuters, so they are watching closely.

The auto-parts record is particularly telling: nearly half of the parts used in US vehicles now come from Mexico. Any tariff increase would ripple through to vehicle prices, potentially hurting both US consumers and Mexican exporters.

What Comes Next: Section 301 and More Talks

Ebrard expects a USTR ruling on a Section 301 investigation regarding structural overcapacity in August 2026. This is separate from the Section 232 tariffs, but it could trigger new trade remedies.

No new formal Section 232 ruling has been issued in August 2026, signaling that the US may be waiting for the outcome of the bilateral talks. President Claudia Sheinbaum’s administration fully backs Ebrard’s line, with the strategy coordinated by her team.

The G20 and the fourth round in September will be crucial moments to test the waters. If the US shows flexibility, Mexico could lock in reductions before the year ends, providing clarity for investors.

If not, the T-MEC review could drag into 2027, keeping the uncertainty alive and weighing on regional investment decisions. Either way, Ebrard’s patient persistence will keep Mexico at the table, ready to defend its trade interests.
