Manufacturers are no longer cautiously testing Mexico. They’re moving decisively, adding capacity, opening new facilities, and scaling operations at a pace that would have felt ambitious just a few years ago.

Across manufacturing hubs like Monterrey, Tijuana, and Ciudad Juárez, production floors are expanding and new plants are coming online to meet sustained demand from North America and beyond. This acceleration isn’t happening by chance. It’s driven by structural advantages that allow manufacturers to move faster once they commit.

At the center of that momentum are the maquiladoras operating under Mexico’s maquiladora program (now the IMMEX program). What began as an export-focused incentive has evolved into a proven platform for scale, one that supports growth while helping manufacturers manage tax exposure, regulatory compliance, and operational risk.

According to data from Mexico’s national statistics agency (INEGI), 6,522 establishments were registered under the IMMEX program as of October 2025, the majority of them engaged in manufacturing. That level of participation points to a manufacturing model built for repeatable growth, not one-off production moves. Below, we look at why maquiladora operations are scaling faster—and what’s making that pace possible.

Maquiladora vs. IMMEX Program

The terms maquiladora and IMMEX are often used interchangeably, but they refer to different things.

A maquiladora is simply a foreign-owned manufacturing facility operating in Mexico that produces goods primarily for export. It describes the type of operation, not the government program behind it. The original maquiladora program was the incentive structure that supported these export factories.

While that program no longer exists in its original form, its benefits were expanded and formalized under today’s IMMEX program (Industria Manufacturera, Maquiladora y de Servicios de Exportación).

IMMEX is an optional export manufacturing incentive that companies can use to support cross-border production. It allows qualified manufacturers to temporarily import raw materials, components, and equipment without paying duties or VAT, as long as finished goods are exported.

In practice, many manufacturers operate maquiladora facilities under the IMMEX program. IMMEX provides the legal and tax treatment, while the maquiladora simply describes the export-focused manufacturing operation itself. Together, they support efficient production in Mexico while helping manufacturers manage compliance and tax exposure.

The Structural Drivers Behind Maquiladoras’ Growth

Nearshoring Shifted the Goal From Stability to Speed

Years of supply chain disruption have reshaped how manufacturers define success. The priority is no longer cost reduction alone; it’s also building supply chains that move faster, respond to disruption, and remain reliable under pressure. Nearshoring emerged as a way to meet those demands.

Manufacturing in Mexico delivers that advantage. Proximity to the United States and Canada shortens lead times and reduces transportation volatility, while trade integration under the USMCA supports more predictable cross-border flows. Those advantages have reshaped regional trade, with Mexico ranking as the United States’ top overall trading partner since 2023.

The IMMEX program supports this shift by reducing friction at the border. Raw materials, equipment, and machinery can move into Mexico duty-free for export manufacturing, allowing companies to increase production without tying up capital in customs and VAT costs. As volumes rise, that flexibility becomes a meaningful competitive advantage.

The IMMEX/Maquiladora Program Is Built for Expansion

Scaling manufacturing adds complexity fast. Higher volumes bring more customs activity, larger payrolls, tighter tax scrutiny, and greater regulatory exposure.

The maquiladora and IMMEX model addresses these challenges at a structural level. Export manufacturing processes are standardized. Customs documentation is traceable. VAT exposure is managed through compliant mechanisms. Income tax alignment, through safe harbor or transfer pricing, adds clarity where ambiguity would otherwise slow growth.

For manufacturers, this structure matters. It allows production and demand to drive expansion decisions, not administrative bottlenecks. Scaling becomes a question of capacity planning, not regulatory negotiation.

Workforce Depth Keeps Expansion Moving

Mexico’s workforce remains one of the most important advantages for manufacturers scaling operations, but it’s no longer a passive benefit. Decades of export manufacturing have built experienced labor pools in industrial regions like Monterrey, Tijuana, Ciudad Juárez, Baja California, and Nuevo León. Workers in these hubs are already familiar with high-volume production and cross-border manufacturing requirements.

At the same time, demand for skilled labor is tightening as manufacturing becomes more automated and production volumes increase. Expansion today isn’t just about hiring more people but about integrating new skills and managing workforce transitions. As roles, compensation structures, and workforce mix evolve, payroll accuracy, labor law compliance, benefits administration, and documentation must evolve with them. When those systems fall out of sync with production, labor gaps widen and growth slows.

This is where shelter services make a meaningful difference. One of the five recognized IMMEX registration types, shelter companies allow foreign manufacturers to operate export manufacturing in Mexico under the shelter’s legal entity and IMMEX registration rather than establishing their own. With employment and labor obligations managed through this structure, manufacturers can scale headcount and adapt skills as production evolves — allowing shelter companies to help absorb workforce growth and shifts without disrupting operations, even as labor markets tighten.

Foreign Direct Investment Is Accelerating Manufacturing Scale

Foreign direct investment continues to flow into Mexico’s manufacturing sector. According to BBVA Research, manufacturing attracted $19.4 billion in foreign direct investment through the third quarter of 2024, representing 51.6% of total FDI during that period. Much of that capital came from reinvestment by manufacturers already operating in Mexico.

Instead of testing the market, manufacturers are adding capacity, upgrading equipment, and extending production lines within existing operations. New facilities are being designed to support future volume, with automation and advanced equipment deployed to increase output without proportionate increases in labor.

The IMMEX model supports this kind of expansion by making scale operationally achievable. With clear rules around imports, exports, and compliance, manufacturers can translate investment into production quickly, allowing capital to fuel growth rather than sit idle in administrative processes.

Mexico’s Manufacturing Model Matches Market Demand

Global markets increasingly reward speed, flexibility, and regional integration. Manufacturing in Mexico aligns with those expectations across industries, from aerospace to industrial equipment.

The maquiladora structure supported by IMMEX fits this reality because it was designed around export efficiency from the start. Production is oriented toward cross-border movement, supply chains are built to serve North American markets, and operations are structured to support volume changes without sacrificing compliance or control.

As manufacturers face shorter product cycles and less tolerance for disruption, that built-in export orientation matters. Rather than adapting legacy structures to meet new expectations, maquiladora operations operating under IMMEX are already aligned with how the market now functions.

Scaling Comes With Real Caveats, Structure Determines the Outcome

The maquiladora and IMMEX framework creates a strong foundation for growth, but scaling manufacturing in Mexico introduces real complexity. As operations expand, the margin for error narrows, and issues that were manageable at smaller scale can have a much greater impact. Mexico also plans to tighten regulations across customs, tax, and labor-related areas.

Manufacturers must ensure that core operational elements stay aligned as they scale, including:

• Customs documentation that accurately reflects import and export activity
• Clear asset ownership and inventory controls
• Invoicing that matches operational reality
• Payroll and labor compliance that scale with headcount

When these elements fall out of sync, audit exposure and operational disruption become more likely. This is where shelter services add real value. By operating under established IMMEX certifications and compliance frameworks, shelter companies allow manufacturers to participate in export manufacturing while minimizing administrative and regulatory burden as operations scale.

Under a shelter model, key risk areas are handled consistently, including:

• Licensing and regulatory compliance
• Payroll, labor administration, and reporting
• Ongoing compliance with IMMEX requirements
• Monitoring exposure related to tax and permanent establishment

Manufacturers retain full control over production, quality, and intellectual property, while administrative and compliance complexity is absorbed by a structure built to support scale.

Rather than slowing expansion, this approach enables it. When risk and compliance are managed proactively, manufacturers can focus on output and efficiency, confident that growth is supported by a framework designed to handle complexity as operations evolve.
