After the USMCA review: what Israeli manufacturers in Mexico should do before 12 January

On 1 July 2026 the three USMCA governments met for the agreement's first six-year joint review. Canada and Mexico confirmed they wanted to extend it for another 16 years. The United States did not. Three weeks later, Washington put a new layer of tariffs on imports from 60 economies, Israel and Mexico among them, with an exemption only for goods that enter under USMCA. Together, those two decisions change the arithmetic for every Israeli company that makes goods in Mexico for the U.S. market.

What happened in July, and what did not

The review did not end the agreement. USMCA stays in force until 1 July 2036, its preferences and rules of origin are unchanged, and the three leaders can still confirm an extension in writing at any time. What changed is the rhythm: without an extension, the parties now review the agreement every year. The U.S. Trade Representative opened the public consultation for the 2027 review on 5 October 2026, with written comments due on 12 January 2027.

In practice this means the agreement is no longer a fixed backdrop for a ten-year investment case. It is a standing negotiation. The live issue with Mexico is rules of origin, above all the U.S. push for more U.S.-specific content in vehicles, which Mexico has tied to relief from U.S. national-security tariffs on autos and metals. As of mid-October, that dispute is unresolved.

Why the July tariffs matter more for Israeli companies

On 24 July 2026 the United States imposed additional duties under Section 301 on goods from 60 economies, following investigations into how each one enforces bans on imports made with forced labour. Economies that already ban and enforce, or have committed to do so, pay 10%; the rest pay 12.5%. Mexico is in the 10% group. Israel is in the 12.5% group. Both duties come on top of the normal tariff, and the U.S.-Israel free trade agreement does not shield Israeli goods from them.

The exemption that matters is narrow: Mexican goods entered duty-free under USMCA do not pay the 10%. The same product can therefore face very different costs depending on where it is made and how it is entered.

For an Israeli company that already produces in Mexico, the gap between the second and third rows is the number to watch. For one still exporting from Israel, the gap between the first and second rows is the case for moving production, provided the product genuinely qualifies.

Origin is now the whole game

Inputs shipped from Israel count as non-originating under USMCA. That does not disqualify the finished product, but it means the product has to earn its origin in Mexico: through the change in tariff classification its rule requires, through a regional value content threshold, or both. Many Israeli operations in Mexico were set up as assembly of Israeli-made components, which is exactly the profile that can fail these tests.

Qualifying is also not enough on its own. Customs brokers report that the exemption follows the entry, not the factory: a good that qualifies but is entered without the USMCA claim and a valid certification of origin pays the 10%. Paperwork that was a formality when the penalty for missing it was a few points of MFN duty is now worth far more.

What the investment figures say

Mexico reported a record US$34.97 billion of foreign direct investment in the first half of 2026, up 2.1% on the same period of 2025, with the United States the source of 48.2%. The headline hides the composition: 88.5% was reinvested earnings by companies already in Mexico. New investment fell to about US$2.73 billion, 13.4% less than a year earlier.

Read together with the review, the signal is that incumbents are deepening their Mexican operations while newcomers wait for clarity. That favours Israeli companies that are already present and can show compliant, qualifying production. For those still deciding, it means the pool of competitors arriving now is smaller, and the institutions courting them are more attentive.

Five things to do before 12 January

• Re-run the origin analysis for every product you ship to the United States, with the Israeli inputs costed as non-originating. Know which rule each product relies on and how much margin it has.
• Audit how your goods are actually entered. Confirm that each shipment carries the USMCA claim and a valid certification of origin, and that your broker treats a missing claim as an error, not a default.
• Model the downside. Price what happens if a product loses USMCA treatment (MFN plus 10%) or if your inputs fall under Section 232, and decide in advance what you would change.
• Decide whether to file comments in the 2027 review. If a proposed change to rules of origin would hit your product, the USTR consultation is the formal channel, and the deadline is 12 January 2027.
• Brief your Mexican counterparts. State economic-development offices and your industry chamber are tracking the bilateral talks closely; make sure they know your operation, your exposure and what you need.

The bottom line

USMCA survived its first review, but on shorter terms than investors had hoped. Combined with the July tariffs, it now rewards Israeli companies whose Mexican production truly qualifies and penalises those whose does not, every year it is reviewed again. Having led Israel's economic and trade mission in Mexico, I would treat the next three months as the time to get the origin case and the paperwork beyond question. If you want to pressure-test yours, I am happy to talk it through.
