If you’re running a manufacturing business in the U.S., you’ve likely felt the pressure: rising labor costs, supply chain uncertainty, and higher tariffs on imported materials. For companies looking to scale without sacrificing margins, manufacturing in Mexico is becoming a clear solution.

But moving production abroad introduces its own complexities — legal structures, compliance, and customs, just to name a few. That’s where the IMMEX program comes in. For decades, it’s been one of the most valuable tools available to support U.S. companies’ manufacturing expansion and unlock real business growth.

Still, for many companies, IMMEX remains confusing or overly complex. To help cut through the confusion, this guide breaks down what the program is, how it works, who qualifies, and why it matters. Whether you’re exploring Mexico for the first time or expanding current operations, you’ll find the clarity you need to decide if IMMEX is right for your business.

What Is the IMMEX Program?

The IMMEX program (Industria Manufacturera, Maquiladora y de Servicios de Exportación) is a trade incentive launched by the Mexican government to attract foreign direct investment and boost the Mexican economy.

It allows foreign companies to temporarily import raw materials, components, and equipment into Mexico duty-free and exempt from VAT,  on the condition that the finished product is exported. This policy is part of Mexico’s broader economic strategy to increase gross domestic product through industrial activity and strengthen its private sector.

IMMEX evolved from the original maquiladora program, which allowed U.S. companies to operate low-cost production facilities in Mexico for re-export. Today, IMMEX supports a more diverse and modern range of industries in Mexico, from automotive and aerospace to electronics and medical devices.

To qualify, companies must:

• Be legally registered in Mexico or operate under a shelter model
• Maintain precise records of imported goods and production output
• Export at least $500,000 annually, or 10% of total sales

Why IMMEX Is a Strategic Choice for U.S. Manufacturers

As more companies seek to reduce dependency on overseas operations, Mexico business growth through IMMEX offers a clear path toward lower costs and greater control over logistics, without compromising quality or compliance.

1. Duty-Free Imports Preserve Cash Flow

One of the biggest advantages of IMMEX is saving on import taxes. Materials, machinery, and parts brought in under IMMEX aren’t taxed like regular imports. That puts money back into your business, money that can be used to:

• Grow operations
• Hire new team members
• Reinvest in infrastructure or R&D

Combine this with Mexico’s lower labor costs, and the result is a significantly more cost-efficient operation.

2. Proximity and Trade Agreements Streamline Supply Chains

Beyond the tax benefits, IMMEX offers logistical advantages. By allowing duty-free, VAT-exempt importation of materials and components, IMMEX helps manufacturers take full advantage of Mexico’s proximity to the U.S.—shortening lead times, cutting freight costs, and simplifying logistics.

Pair that with the United States-Mexico-Canada Agreement (USMCA), formerly the North American Free Trade Agreement (NAFTA), which ensures preferential treatment for most exported goods, and you get a streamlined, cost-effective supply chain anchored in North America. IMMEX acts as the operational backbone that lets you move faster, more affordably, and with fewer customs complications.

3. A Legal and Operational Structure That Works

IMMEX isn’t a plug-and-play solution, but it doesn’t have to be complicated either. Many manufacturers use a shelter model to operate under Mexico’s system without having to set up their own company there.

Instead of dealing with the complexities of establishing a new legal entity, they’re able to start operating quickly and keep their attention on running and growing their core business, without getting lost in regulatory red tape.

IMMEX in the Broader Economic Landscape

The success of the IMMEX program isn’t hypothetical. It’s measurable. As of January 2025, according to Mexico’s Instituto Nacional de Estadística y Geografía, 6,530 establishments were active under IMMEX. Together, they employed over 3.2 million people and generated 720.5 billion pesos in revenue that month alone, with more than 57% of that tied to exports.

IMMEX continues to drive Mexico’s export economy, expand its private sector, and position the country as a key manufacturing partner within North America. Its structure supports faster, more efficient trade while giving manufacturers cost advantages and access to international markets.

Compliance & Operational Considerations

Of course, no program this powerful is without requirements. To remain compliant under IMMEX, manufacturers must pay close attention to detail. This includes:

• Accurate inventory tracking of all goods and services temporarily imported
• Filing regular customs declarations and reports with the Mexican government
• Meeting minimum export thresholds
• Adhering to rules under USMCA and domestic trade law

Failing to meet these standards can result in penalties or the loss of IMMEX status. That’s why many companies choose to work with experienced shelter partners, like NAPS, who specialize in operating in Mexico under IMMEX.
