The History of Maquiladoras in Mexico

Timeline Overview: Six Decades at a Glance

The maquiladora program has gone through five distinct phases since Mexico launched it in 1964. Each phase was triggered by a specific economic or policy event, and each fundamentally changed how foreign manufacturers operated in the country.

1964–1971: The Border Industrialization Program

Mexico's maquiladora program began in 1964 as a direct response to the end of the Bracero Program, which had sent millions of Mexican workers to US farms and factories since 1942. When the program ended, tens of thousands of workers returned to border cities with no employment prospects. Mexico's government needed to create jobs, and US manufacturers needed lower-cost production. The National Border Industrialization Program solved both problems.

The program's core mechanism was simple and has not fundamentally changed in six decades: foreign companies could import raw materials into Mexico duty-free, manufacture products, and export them without paying Mexican import duties. The catch was geographic — operations were restricted to a 20-kilometer strip along the US border — and practical: the final product had to be exported.

A handful of US electronics companies set up the first maquiladoras in Tijuana. Growth was slow. The peso's value at the time offered limited cost advantage over domestic US production, and most American manufacturers had not yet faced the competitive pressures that would later make cross-border manufacturing essential. By 1970, roughly 120 maquiladoras employed around 20,000 workers — a modest start for what would become a $617 billion export economy. But the slow takeoff illustrates a principle that still applies: maquiladora adoption accelerates when regulations and economics align simultaneously. Every surge in the timeline below was triggered by a policy change, not by organic demand alone.

1972–1993: Currency Crisis, Deregulation, and Growth

The maquiladora program's real growth was triggered not by policy design but by economic crisis. Mexico borrowed heavily in the 1970s to fund oil exploration, and when global oil prices collapsed in the early 1980s, the peso devalued sharply. The resulting debt crisis created an urgent need for hard currency that coincided with US manufacturers' growing need to reduce production costs in an increasingly competitive global economy.

The Mexican government recognized the opportunity. Throughout the 1980s, it lifted foreign investment restrictions that had limited maquiladora expansion beyond the border zone. The most significant reform came in 1989 with the Decree for Development and Operation of the Maquiladora Industry, which allowed maquiladoras to sell up to 50% of their output in domestic Mexican markets — a fundamental shift from the export-only model.

The combined effect of peso devaluation and regulatory liberalization was dramatic. The maquiladora count grew from roughly 120 facilities in 1970 to over 2,000 by 1993, employing more than 500,000 workers. Automotive and electronics companies led the expansion, drawn by labor cost advantages that the currency crisis had made even more compelling. This period established the pattern that repeats in every subsequent era: economic disruption creates the opening, and policy reform determines who captures the opportunity. The 1989 domestic sales rule is still relevant today — under IMMEX, manufacturers can sell into the Mexican market as well as export, giving operations dual-market flexibility that pure export models lack.

1994–2006: NAFTA Transforms the Model

NAFTA, which entered into force on January 1, 1994, was the single most consequential event in maquiladora history. The North American Free Trade Agreement created the world's largest free trade area, connecting more than 400 million people and systematically eliminating tariffs across the US, Mexico, and Canada. For manufacturers, the economics changed overnight.

The model's durability was tested almost immediately. In December 1994, Mexico's peso lost more than half its value against the dollar, triggering what became known as the Tequila Crisis. Mexico's GDP contracted roughly 6% and unemployment doubled. But maquiladoras, structured around dollar-denominated transactions, were largely insulated. Labor costs effectively dropped by more than half in dollar terms, making Mexico one of the most cost-competitive manufacturing locations in the world. Foreign investment accelerated rather than retreated — major electronics manufacturers expanded operations in Tijuana during the crisis rather than pulling back. The episode established a structural principle that holds today: the maquiladora model's dollar-denominated framework provides a natural hedge against peso volatility.

Under NAFTA, maquiladoras gained preferential duty treatment on a far broader range of products than the original Border Industrialization Program had allowed. The geographic restrictions that had confined operations to the border zone were already loosening, and NAFTA accelerated expansion into central Mexico's Bajío region. Two-way trade between the US and Mexico grew from $81 billion in 1993 to $345 billion by 2006, according to US Census Bureau trade data — a more than four-fold increase in barely a decade.

The maquiladora program faced its most significant competitive test when China joined the World Trade Organization in December 2001. The combination of China's entry into the global export market and the US recession compressed Mexico's lower-value assembly operations — approximately 500 maquiladoras closed between 2001 and 2003, and employment fell by roughly 300,000 workers, according to a U.S. Government Accountability Office report. But the contraction was concentrated in low-skill sectors like basic textiles and simple assembly. Automotive, aerospace, and electronics plants weathered the pressure far better. The recovery that followed turned competitive threat into structural advantage. The maquiladoras that emerged specialized in automotive, aerospace, and electronics — segments where proximity, supply chain integration, and workforce skill matter more than labor-cost arbitrage alone. That industrial upgrade is a direct reason why today's IMMEX operations look nothing like the assembly plants of the 1960s, and why manufacturers in those sectors evaluating Mexico today are evaluating the same competitive moat that protected those operations from the China Shock.

NAFTA also changed what maquiladoras produced. The border-zone assembly plants of the 1960s and 1970s gave way to integrated manufacturing operations producing finished goods for the North American market. Automotive production expanded significantly, with Mexico developing the supplier networks and workforce capabilities to build complete vehicles rather than just wire harnesses and simple assemblies. The U.S.-Mexico-Canada Agreement that replaced NAFTA in 2020 built on this foundation while tightening rules of origin, particularly for automotive components.

2006–2020: IMMEX Modernizes the Framework

In 2006, Mexico merged the Maquiladora Decree and PITEX (a parallel program for non-maquiladora exporters) into a single framework: the IMMEX program (Industria Manufacturera, Maquiladora y de Servicio de Exportación). The consolidation simplified compliance for manufacturers who had been navigating two overlapping regulatory regimes and created the structure under which maquiladoras operate today.

IMMEX created five distinct operating modalities: Holding Company, Industrial, Services, Shelter, and Outsourcing. The Shelter modality is particularly relevant for foreign manufacturers entering Mexico for the first time, because the Mexican shelter services provider holds the IMMEX registration and assumes administrative, legal, and compliance responsibilities on behalf of the foreign company. For a detailed breakdown of how the program works operationally, including all five modalities and compliance requirements, see our guide to the IMMEX program.

The impact on export growth was substantial. Mexico's total exports grew 99% from $210 billion in 2005 to $419 billion in 2017, with manufactured goods consistently accounting for roughly 90% of export revenue, according to INEGI's IMMEX data program. By the time USMCA replaced NAFTA in 2020, the IMMEX program had become the dominant legal framework for export manufacturing in Mexico, with more than 6,500 active registrations. That stability was about to face two converging disruptions: a global pandemic and the most significant rewrite of North American trade rules in a generation.

2020–2026: USMCA, Nearshoring, and the New Trade Reality

The COVID-19 pandemic exposed critical vulnerabilities in global supply chains built around low-cost Asian manufacturing. Factory shutdowns, port congestion, and weeks-long shipping delays forced manufacturers to rethink where and how they produced goods for the North American market. Mexico's manufacturing sector demonstrated its proximity advantage during the recovery: after an initial shutdown in March 2020, the majority of maquiladora operations had resumed by early June, while many competing Asian manufacturing locations remained constrained by port congestion and shipping delays that persisted well into 2021. When your Manufacturing Campus is a same-day truck drive from a US distribution center rather than a six-week ocean voyage, supply chain recovery happens faster. The result was a nearshoring wave that reshaped Mexico's industrial landscape.

Mexico overtook China as the United States' largest trading partner in 2023 and maintained that position in 2024, when bilateral goods trade hit a record $840 billion, according to the US Census Bureau. Foreign direct investment surged alongside the trade numbers. In the first nine months of 2025 alone, Mexico attracted $40.9 billion in FDI, per the Secretaría de Economía, with manufacturing accounting for 37% of that investment.

This growth did not go unchallenged. In February 2025, the United States imposed 25% tariffs on Mexican goods that do not comply with USMCA rules of origin. The practical impact has been more nuanced than the headline rate: approximately 85% of Mexico's exports to the US qualify under USMCA and continue to enter duty-free. But the policy shift elevated compliance from an optional advantage to a core operational requirement.

Mexico's regulators responded with their own enforcement wave that had a clarifying effect on the industry. More than 600 IMMEX programs were suspended in 2025 for compliance failures, reducing the active count from approximately 6,550 to 5,821 by February 2026, per the SNICE portal. For manufacturers operating through established shelter services frameworks with dedicated compliance infrastructure, the crackdown actually improved competitive positioning — compliance management is now table-stakes, and the shelter model, where permanent establishment risk and regulatory requirements are actively managed by the operator, is precisely the structure built for this environment.

USMCA also triggered Mexico's most significant labor reform in a century. In May 2019, Mexico overhauled its labor law to require secret-ballot union elections, independent labor courts, and transparent collective bargaining — replacing an older system of opaque legacy arrangements. For manufacturers, the practical effect has been greater predictability: labor relations are now governed by clear, enforceable rules aligned with international standards. The reform coincided with a deliberate wage policy that has more than tripled Mexico's daily minimum wage since 2018, including nine consecutive years of double-digit increases. Most maquiladoras already pay well above the minimum, but the upward trend has improved workforce stability and retention across northern Mexico's manufacturing corridors — addressing what had been one of the sector's persistent operational challenges. For the full picture of what manufacturing labor costs in Mexico today, see our benchmark guide.

The USMCA joint review, scheduled to begin July 1, 2026, will determine whether the agreement continues, is renegotiated, or is allowed to expire. The outcome will shape the next era of maquiladora operations — but if the program's 60-year track record is any guide, compliant manufacturers operating within robust frameworks have consistently emerged stronger from each transition.

What 60 Years of Evolution Means for Your Decision

Every era in this timeline shares a pattern. A disruption — currency crisis, trade agreement, pandemic, tariff escalation — creates uncertainty. Manufacturers who operate within the strongest available compliance framework at the time capture disproportionate gains when the dust settles. Those operating outside those frameworks face suspension, tariff exposure, or competitive disadvantage.

That pattern is playing out again right now. The combination of 25% tariffs on non-USMCA goods, 600+ IMMEX suspensions, and the approaching USMCA joint review is raising the compliance bar higher than at any point since the IMMEX program was created. The manufacturers best positioned for whatever comes next are those with USMCA qualification already embedded in their operations, IMMEX compliance actively managed, and supply chains structured to absorb policy changes without operational disruption.

The maquiladora model has evolved alongside each policy shift. Today's Manufacturing Campus model consolidates workforce recruitment, regulatory compliance, logistics infrastructure, and operational support into a single integrated environment — a direct response to the complexity that 60 years of regulatory layering has created. Rather than coordinating separately with a landlord, staffing agency, customs broker, and logistics provider, manufacturers can focus on production while the campus operator handles the rest. For a full breakdown of what this operating model looks like in practice, including the four modes of entry into Mexico manufacturing, see our guide to maquiladoras in Mexico.

Frequently Asked Questions

When did the maquiladora program start?

Mexico launched the maquiladora program in 1964 through the National Border Industrialization Program. The program was created in response to the end of the US-Mexico Bracero Program, which had employed millions of Mexican workers in the United States. The first maquiladoras were US electronics companies that opened factories in Tijuana and Ciudad Juárez, taking advantage of duty-free imports on materials used to manufacture goods for export.

How did NAFTA change maquiladoras in Mexico?

NAFTA, which entered into force on January 1, 1994, was the most consequential event in maquiladora history. It eliminated tariffs across the US, Mexico, and Canada, expanded preferential duty treatment to a broader range of products, and accelerated the growth of maquiladora operations beyond the original border zone. US-Mexico trade grew from $81 billion in 1993 to $345 billion by 2006. NAFTA also transformed maquiladoras from simple assembly operations into integrated manufacturing facilities producing finished goods for the North American market.

What replaced the original maquiladora program?

In 2006, Mexico replaced the Maquiladora Decree with the IMMEX program (Industria Manufacturera, Maquiladora y de Servicio de Exportación). IMMEX merged the original maquiladora framework with PITEX, a parallel program for non-maquiladora exporters, into a single regulatory structure. The program created five operating modalities — Holding Company, Industrial, Services, Shelter, and Outsourcing — and established the compliance framework under which all export manufacturers in Mexico operate today. As of February 2026, there are 5,821 active IMMEX programs registered with the Secretaría de Economía.

How many maquiladoras were there in the 1990s compared to today?

By the early 1990s, Mexico had approximately 2,000 maquiladoras employing over 500,000 workers. That number peaked at roughly 3,500 facilities in the early 2000s during the NAFTA-era boom. Today, the program operates under the IMMEX framework, with 5,821 active IMMEX-registered programs as of February 2026, per the Secretaría de Economía, employing more than 3 million workers. The decline from the 2025 peak of approximately 6,550 active programs reflects Mexico's enforcement crackdown, which suspended over 600 registrations for compliance failures.

What was the Border Industrialization Program?

The Border Industrialization Program was the Mexican government initiative launched in 1964 that created the maquiladora model. It allowed foreign companies to import raw materials into Mexico duty-free, manufacture or assemble products within a 20-kilometer zone along the US border, and export the finished goods without paying Mexican import duties. The program was designed to create employment in border cities after the end of the Bracero Program and to attract foreign investment. It laid the foundation for what became Mexico's IMMEX program, now the legal framework governing all export manufacturing in the country.
