For many companies, Mexico is no longer seen as a low-cost alternative alone. It is considered a strategic hub for long-term growth, supply chain resilience, and access to the North American market. Proximity to the U.S. means companies can serve their largest customer base more efficiently, while also taking advantage of reduced transportation costs and faster turnaround times compared to overseas operations.
Mexico’s maquiladora program (now the IMMEX program) and its contribution of high-quality manufacturing operations at a lower cost have made the country a primary source for manufacturing in a variety of sectors, including electronics, aerospace, medical devices, and the automotive industry. Mexico is also increasingly recognized for its role in innovation and product development, not just assembly, as companies leverage the local talent pool for engineering and design.
The program enables foreign companies to operate in Mexico under a preferential, low-tax cost structure while still taking advantage of Mexico’s skilled and affordable labor force. This combination of cost competitiveness and operational support has helped Mexico cement its role as a manufacturing powerhouse in the global economy, rivaling traditional offshore destinations.
Let’s take a closer look at the IMMEX program. We’ll also share practical guidance based on NAPS’ decades of experience guiding companies through setup, certification, and ongoing operations in Mexico.
What Are Maquiladoras?
What Is the IMMEX Program?
The IMMEX program, formally known as the maquiladora program, allows foreign manufacturers to import raw materials and components into Mexico, tax- and duty-free, under the condition that 100% of all finished goods will be exported out of Mexico within a government-mandated time frame.
This arrangement makes IMMEX one of the most cost-effective ways to set up international manufacturing. It lowers upfront costs, accelerates production timelines, and reduces risk by allowing companies to bypass the burden of multiple import taxes and duties. For companies new to Mexico, IMMEX often represents the difference between a lengthy, costly entry process and a streamlined, efficient launch.
Key Objectives of IMMEX
- Expand the Mexican economy by enabling foreign companies to manufacture in a competitive environment and attract foreign direct investment.
- Create jobs throughout the socioeconomic spectrum, from entry-level assembly roles to highly skilled engineering positions.
- Introduce new technology and innovation by encouraging companies to bring specialized equipment, processes, and know-how into the country.
- Offer a tax incentive and operational efficiencies to foreign companies, making Mexico a preferred destination compared to Asia or Eastern Europe.
In other words, the IMMEX program is designed to be a win-win solution. Mexico gains jobs, investment, and knowledge transfer, while foreign companies gain a competitive cost structure, better inventory control, and a stable, reliable manufacturing base close to the U.S.
What Are Maquiladoras?
Maquiladoras in Mexico are factories that are owned and operated by a foreign company. They manufacture the company’s products in Mexico, then subsequently export the finished product to other countries. In many cases, these facilities operate as extensions of a company’s global supply chain, producing goods that meet the same quality and safety standards as plants in the U.S., Europe, or Asia.
These factories operate under preferential tax and fiscal programs administered by the Mexican government. Most production equipment and materials used in maquiladoras are allowed to enter Mexico on a temporary import basis, which avoids the need to pay import taxes. This flexibility allows companies to reduce upfront investment costs while maintaining the ability to adapt quickly to changing market demands or production schedules.
Why Maquiladoras Work So Well
- Strategic Location: Border cities like Tijuana, Juárez, and Reynosa allow easy access to the U.S. market.
- Cost Efficiency: Companies save on import duties, wages, and shipping costs.
- Skilled Labor: Mexico’s workforce is experienced in technical manufacturing, with strong training programs in engineering and industrial design.
- Established Ecosystem: Supply chains, logistics providers, and industrial parks are already in place.
For decades, maquiladoras have been the backbone of Mexico’s export economy, driving billions of dollars in trade annually. The IMMEX program provides the framework that allows them not only to survive but to thrive in a competitive global market.

Maquiladora Program Overview
The beginning
Following the end of the Bracero program, the maquiladora program began in 1965, launched by the Mexican government as a means of alleviating unemployment problems along the borders while also strengthening economic ties with the United States. It provided foreign companies with various tax- and duty-free benefits, special customs terms, and simplified access to skilled, affordable labor. This arrangement was particularly attractive to the manufacturing industry, which was searching for new ways to cut costs and remain competitive in a changing global market. By 1985, maquiladoras had grown into a dominant economic force, becoming the largest single source of foreign exchange in Mexico and laying the groundwork for decades of industrial growth.
Maquiladora boom
The maquiladora program truly boomed in 1994 with the approval of the North American Free Trade Agreement (NAFTA). This landmark agreement opened new trade lines between Canada, the United States, and Mexico by eliminating most tariffs and other barriers to free trade between the three countries. The agreement also removed restrictive quotas that had previously limited collaboration, enabling maquiladoras to operate more freely across multiple industries. This change not only encouraged U.S. companies to expand in Mexico but also attracted foreign direct investment from European and Asian manufacturers eager to access the North American market. The boom period marked a dramatic increase in plant expansion and the creation of highly specialized industrial clusters across Mexico.
From then on
Since then, the manufacturing industry in Mexico has consistently made up roughly 50% of the country’s total exports, highlighting its central role in national economic development. Over the years, maquiladoras have created more than a million jobs throughout over 3,000 export assembly and manufacturing plants, spanning industries from automotive to medical devices. These jobs have not only fueled local economies but have also elevated Mexico’s reputation as a trusted global manufacturing partner. Today, one of the easiest ways to establish a maquiladora and save on operating expenses is by operating under a shelter company, which allows foreign firms to quickly access the benefits of the IMMEX program without navigating complex regulations alone.
Why Have Some Companies Set Up Offshore Assembly Plants
The Globalization Push
In the late 20th century, globalization pushed many U.S. manufacturers to explore offshore assembly plants in regions such as China, Vietnam, Malaysia, and India. The goal was straightforward: reduce operational expenses while maintaining production volume. Labor costs in Asia were a fraction of U.S. wages, and governments in these countries often provided subsidies, tax breaks, and relaxed regulations to attract foreign investment.
Another factor driving offshore expansion was the rise of container shipping and global logistics networks. Standardized shipping containers allowed companies to move goods cheaply and efficiently across oceans, making distance less of a concern. As a result, companies in industries ranging from consumer electronics to textiles saw an opportunity to scale production rapidly by building plants overseas.
For several decades, this outsourcing strategy worked well. Companies enjoyed cheaper labor, fewer compliance hurdles, and expanded access to growing Asian markets.
These factors mean that the once “obvious” choice of China is no longer the default for North American companies. Many businesses are now actively diversifying their supply chain management strategies to reduce exposure to these risks.

Why Mexico Is More Viable Now
Nearshoring in Mexico has emerged as the strongest alternative to Asian offshoring. The IMMEX program and the maquiladora framework make it not only cost-effective but also strategically advantageous:
- Geographic Proximity: Mexico shares a 2,000-mile border with the United States. Finished goods can be shipped within days, compared to weeks by ocean freight from Asia. This proximity also facilitates quality control and communication with local teams.
- Reduced Transportation Costs: Shorter supply chains mean lower freight bills, fewer customs complications, and less exposure to global shipping disruptions. For industries like automotive and electronics, where speed-to-market matters, this can be a decisive advantage.
- Skilled Workforce: Mexico graduates thousands of engineers and technicians annually. Industrial clusters in states like Baja California, Sonora, Querétaro, and Nuevo León provide a labor force trained for complex industries such as aerospace, automotive, and medical devices.
- Trade Protections: The USMCA provides a legal framework that ensures fair treatment, protects intellectual property, and reduces trade barriers across North America. This gives manufacturers peace of mind that operations will remain stable and predictable.
- Flexible Operations: The IMMEX program allows for temporary duty-free imports, letting companies bring in equipment, raw materials, and parts without paying upfront taxes, as long as goods are exported. This lowers entry costs and accelerates time-to-market.
- Sustainability and ESG Benefits: Nearshoring to Mexico also reduces a company’s carbon footprint. Shorter transportation routes mean lower emissions, which helps organizations meet environmental, social, and governance (ESG) commitments.
Together, these benefits make Mexico not just a cheaper option but a smarter long-term strategy for companies seeking resilience, productivity, and growth.

The country is a major auto manufacturer, home to 89 of the world’s top 100 auto part makers. Other common Mexico manufacturing industries include:
IMMEX Certification & Permits: How to Approach the Process
Why trust a shelter company?
Navigating the IMMEX certification process independently can be complicated, time-consuming, and fraught with regulatory compliance hurdles. Companies must interact with multiple government agencies, prepare detailed documentation in Spanish, and remain compliant with strict customs and tax laws. Even minor errors in applications or reporting can result in costly delays, fines, or even the loss of certification altogether. For companies eager to start operations quickly, these administrative challenges can stall momentum and drain resources before production even begins.
A shelter company eliminates these risks by providing a proven, pre-established framework for operating under the IMMEX program. Because shelter firms already hold IMMEX authorization, foreign manufacturers can begin production in as little as four weeks, rather than the months, or sometimes years, required to receive their own permit approval. This not only accelerates market entry but also minimizes exposure to compliance missteps. By trusting a shelter company, manufacturers gain peace of mind knowing that their operations are backed by local expertise, established processes, and a track record of keeping international clients compliant with Mexican laws and regulations.
What does a shelter company do?
A shelter company acts as a comprehensive operational partner for foreign manufacturers entering Mexico. Instead of building a legal entity from scratch, hiring administrative staff, and managing permits on their own, companies can “plug into” the shelter’s infrastructure. This includes everything from legal incorporation and customs compliance to payroll management and HR support. Shelter companies also help with site selection, factory setup, and coordination with local suppliers, allowing manufacturers to focus on what they do best: producing quality goods.
Beyond administrative support, shelter companies also provide ongoing risk management and scalability. They stay up to date with evolving labor laws, tax reforms, and environmental issues so manufacturers don’t have to. They can also help companies expand operations seamlessly, whether that means hiring more employees, adding shifts, or relocating to a larger facility. By handling these complexities, shelter providers free up resources and shorten the learning curve for businesses that are new to Mexico’s manufacturing landscape.
