Mexico Auto Parts Sector Loses 180,000 Supply Chain Jobs

Mexico’s automotive manufacturing sector is experiencing a sustained labor contraction, driven by US import tariffs, shifts in electric vehicle demand, corporate cost-cutting, and accelerating factory automation.

Data from the INEGI and industry analysis reveal that the industry has shed tens of thousands of formal jobs over the past two years, with component suppliers bearing the brunt of the downturn.

According to Inegi’s Monthly Manufacturing Industry Survey (EMIM), total employment across automobile, truck, body, trailer, and auto parts manufacturing fell to 742,000 workers in April. This represents a decline of 50,000 positions compared to April 2025 and a cumulative loss of 107,000 jobs over a two-year period. Previous EMIM data showed that by the end of the first quarter, workforce levels had fallen to 797,000, the lowest level recorded for that period since at least 2018, marking a 56,000-job drop over a 12-month span.

The payroll adjustments are heavily concentrated in component manufacturing rather than final assembly plants. Of the 107,000 jobs eliminated over the two-year period, parts manufacturers accounted for 91,000 cuts. Vehicle and truck assembly plants reduced 10,000 positions, while body and trailer manufacturers cut 6,000 jobs.

Labor economist Willebaldo Gómez estimated that total job losses in the auto parts subsector have reached approximately 180,000 when compared to employment levels prior to the implementation of US tariffs, out of a broader loss of 240,000 jobs across Mexico's entire manufacturing sector.

“Perhaps the most important data, not in the assembly industry, not in the industry that manufactures automobiles, but in the auto parts sector, what we have detected is an evident decrease in job positions over the last year. This is due to two factors: first, companies are trying to become much more flexible in terms of costs, where the labor issue is very important; and the other factor beginning to have an impact is automation processes, which are displacing workforce volume,” Gómez said.

Trade Uncertainty and Negotiating Power

The labor decline coincides with trade measures enacted by the United States. Late last March, President Donald Trump signed an executive order imposing a 25% tariff on vehicles imported into the US. Under the USMCA, the tariff applies specifically to components not manufactured within the US.

Between January and April, Mexican automotive exports to the US fell by 5.1% . Despite the drop, the automotive sector remains Mexico’s primary source of foreign currency, generating US$59 billion in export revenue during the four-month period, triple the US$20 billion received in remittances and more than four times the US$13 billion generated by international tourism.

Analysts at Banco Base linked the workforce reductions directly to the US tariffs and highlighted broader investment headwinds in Mexico, including deteriorating rule of law, low business confidence, and persistent trade uncertainty.

Gómez noted that international market volatility has altered collective bargaining dynamics, weakening union leverage during annual contract and wage reviews.

“What we observe is a drop in employment, especially in the auto parts sector—that is perhaps the most obvious feature. The other piece of data that emerges, especially after this first semester of 2026, is that this international discussion of instability and uncertainty benefited companies when negotiating both wage increases and contractual reviews. Why? Because they present a very complicated outlook, leading them to offer smaller margins of growth in both wages and benefits,” Gómez said.

He added that key labor objectives established during USMCA negotiations have yet to materialize. “What was sought with the USMCA, particularly with the annex to Chapter 23 regarding wage equality, has not been achieved,” he said.

EV Policy Shifts and Long-Term Outlook

Industry analysts point to additional demand shocks impacting vehicle assembly. Automotive analyst César Roy cited the elimination of the US$7,000 consumer tax credit for electric vehicles in the US as a major catalyst for declining vehicle assembly.

“They removed the US$7,000 bonus, and that generated low demand for electric cars and trucks produced in the United States and Mexico,” Roy said. He added that tariffs squeeze dealer margins in the US, eliminating incentives to run sales promotions on these units.

Manuel Valencia, an academic at Tec de Monterrey’s School of Business, noted that while tariffs are the primary factor driving labor cuts, OEM restructuring has also played a role. However, Valencia projected that the conclusion of USMCA trade reviews in July could restore market certainty and stabilize employment.

“Jobs will recover and will also continue to become more sophisticated—meaning more technical jobs focused on the industry's ongoing transitions,” Valencia said.

Valencia highlighted domestic manufacturing shifts as a positive indicator for future labor absorption. General Motors recently announced plans to begin manufacturing two additional models—the Chevrolet Groove and Aveo—at its Ramos Arizpe plant in Coahuila starting in 2027. The move is part of the automaker's strategy to expand North American production and replace imports previously sourced from China.

The National Bank for Foreign Trade (Bancomext) emphasized that the auto industry's recovery remains critical for Mexico's broader economy. Beyond generating direct employment, the sector drives technology transfer, fosters advanced manufacturing ecosystems, and provides a foundational platform for suppliers to transition into high-value-added sectors such as aerospace.
