Rio South Texas, a Supply Chain Hub Like No Other: COSTEP

Q: For those unfamiliar with the subject, what is the Rio South Texas region? What is COSTEP’s role in this environment?

A: As a 501(c)(3) public charity, COSTEP dedicatedly serves the bi-national corridor spanning South Texas and Northern Tamaulipas. On the US side, our territory encompasses a seven-county region stretching from Brownsville to Laredo. Because "Rio Grande Valley" and "Laredo" represent two distinct, well-established economic areas, unifying them under a single identity led us to establish the "Rio South Texas" brand, an umbrella that bridges both Texas regions alongside the adjacent Mexican municipalities from Nuevo Laredo to Matamoros.

Our core mission centers on regional promotion and strategic economic development. COSTEP works to attract high-value foreign direct investment, capture advanced manufacturing operations, and build a robust, integrated industrial ecosystem across both sides of the Rio Grande.

Q: What can this region tell us about the state of the Mexico-US relationship in terms of economic cooperation and integration? 

A: While broader political shifts can create temporary political tension, our cross-border dynamic remains deeply integrated. We operate as a unified, binational community defined by decades of shared industry and daily collaboration. This region has an identity distinct from the interiors of both nations: South Texas differs significantly from the rest of the United States, just as Northern Tamaulipas operates differently from the rest of Mexico. Every day, people cross the border to work, conduct business, and attend university on either side. This fluid, daily exchange forms a single, interdependent ecosystem that natively supports both industrial growth and workforce development.

Fold the globe in half, and you will find our region sitting smack in the middle of the North American supply chain. Whether servicing central and South America to the south, or reaching deep into the United States and Canada to the north, virtually every manufactured component and perishable goods finished in Mexico must cross through this border corridor to reach its final consumer.

Our advantage extends beyond central logistics to deep cultural alignment. We face minimal language barriers because our workforce seamlessly bridges both worlds, often conducting business in our authentic regional Spanglish to move operations forward effortlessly. This structural connectivity is best demonstrated at the Laredo port of entry, the largest land port in the nation, where between 17,000 and 20,000 commercial trucks cross daily to keep North American industry moving.

Q: For those companies seeking a place to relocate, why choose this region and not another, such as the Bajio or Central region? In which products or manufacturing processes is this region more competitive?

A: A recent inventory published on our website details the industrial capacity active within the region. The assessment deliberately excludes general food processing to focus exclusively on advanced manufacturing capabilities. The data reveals three core processing pillars driving the local ecosystem: 110 metalworking and tooling operations, 104 electrical-electronics assembly plants, and 75 plastic injection molding facilities.

These foundational capabilities directly power tier-one production across several critical global industries, including automotive, consumer appliances, medical devices, construction equipment, and aerospace. While these high-capacity operations represent our established industrial core, the inventory also highlights significant potential among smaller tier-2 and tier-3 suppliers. The presence of these specialized micro-suppliers indicates immense headroom for supply chain localization, industrial expansion, and strategic capital investment throughout the corridor.

Q: Which sectors have untapped potential for further expansion?

A: Historically, our industrial ecosystem has focused heavily on the automotive supply chain. While we do not operate a complete vehicle final-assembly plant, local facilities produce between 50% and 60% of the individual components required to manufacture a modern automobile. Complete vehicle assembly remains a viable long-term objective for the region, but our current industrial expansion extends well beyond traditional automotive manufacturing.

Aerospace, in particular, has experienced significant momentum. Although advanced aerospace operations have maintained a presence in the corridor for years, high-profile projects like the SpaceX Starbase facility in Cameron County have placed the region on the global map. This international visibility has elevated our profile among prospective investors across Europe and Asia. Beyond visibility, the region has deep operational experience and specialized training capacity to support high-tech manufacturing workforces. Our growth strategy does not depend solely on attracting a central OEM or a single Tier 1 manufacturer. Instead, we aim to diversify existing operations, scale specialized component production, and expand the overall scope of advanced manufacturing capabilities in the region.

Q: How adaptable is the manufacturing workforce in Rio South Texas, and can local suppliers support industries beyond traditional automotive assembly?

A: The data from our regional inventory brought a crucial operational reality to light. Many of our manufacturers misidentify their own capabilities by framing themselves strictly around a single end market. A plant making precision parts is not just an automotive company; it is a metalworking, plastic injection molding, or electronic assembly operation. That same shop floor can produce components for an aircraft, a home appliance, or a medical device just as easily as it does for a car.

When we define these companies by their core manufacturing processes rather than the logo on their shipping box, the true flexibility of our region becomes obvious. The foundational skill sets of our workforce are already here and easily transferable, requiring minimal cross-training or specialized certification to shift from one industry to another. That operational adaptability allows our local manufacturers to seamlessly supply multiple sectors across the United States and global markets, making our entire industrial base far more competitive and resilient.

Q: COSTEP treats the Rio South Texas region as a unified, binational economic zone spanning both southern Texas and northern Tamaulipas. How do you overcome the challenge of pitching a region that crosses international borders, differing legal jurisdictions, and distinct local municipal interests as a single, cohesive destination for global capital? 

A: When presenting our region to prospective investors, we lead with our unparalleled physical and strategic infrastructure. The corridor boasts 19 international crossings connecting Texas and Tamaulipas, seven international airports across both sides of the border, extensive freight rail networks, and a deep-water maritime ecosystem featuring the Port of Brownsville alongside the ports of Harlingen, Port Mansfield, and Port of Matamoros. From a logistics and asset standpoint, no other region in the United States offers a comparable level of cross-border connectivity. Combined with a very competitive cost of living, this infrastructure forms a formidable foundation for industrial scale.

Our educational ecosystem serves as another premier asset driving regional growth. With major university systems like the University of Texas and Texas A&M operating alongside dynamic two-year colleges and specialized technical centers on both sides of the river, our talent pipeline is robust. 

To maximize this resource, COSTEP is currently building an inventory of higher education programs across the binational area. A direct side-by-side comparison between this academic data and our advanced manufacturing inventory helps us identify training gaps, pinpoint strategic opportunities, and align degree programs directly with industrial needs. This proactive alignment ensures incoming and expanding companies have direct access to a highly skilled, ready-to-work labor force.

Q: From your perspective, what are the primary strategic advantages that the Rio South Texas region offers to pull production lines away from Asia?

A: The twin-plant operational model has long defined our cross-border commercial strategy. Historically, labor-intensive assembly takes root on the Mexico side, while power-intensive processing, administration, warehousing, and logistics settle on the United States side. Today, trade shifts and updated rules under the USMCA are accelerating interest in this co-location model. Companies across Asia, Europe, South America, and Mexico actively seek ways to establish or expand production within North America.

When we engage foreign investors, we do not ask them to relocate their existing operations. We present our corridor as the ideal platform for strategic expansion and USMCA compliance. Few places on earth can replicate our binational efficiencies. Components often cross the border up to six or seven times during production, moving within Foreign Trade Zones (FTZs) that defer duties until final delivery.

If evaluated as a standalone economic entity, the entire United States-Mexico border region would rank among the five largest economies globally. Our corridor is far more than a point of entry or a warehouse staging ground; we are a fully integrated, high-capacity manufacturing engine built for global business.

Q: COSTEP recently launched the Rio South Texas Region Binational Autocluster to formalize cross-border automotive integration. How does this cluster change the way Tier 1 and Tier 2 suppliers coordinate production between northern Tamaulipas and South Texas?

A: When COSTEP launched its binational cluster initiative, our primary goal was not to build another membership-based trade association. Instead, we established a connective platform designed to unite existing industrial clusters, starting in Mexico, where mature automotive and aerospace networks are already thriving. We want these established groups to recognize the full potential of our region, and we act as the operational bridge that facilitates their entry into the North American market.

Many successful international entrepreneurs possess exceptional products and ambitious expansion plans, yet they lack a clear roadmap for navigating the United States regulatory and commercial landscape. We eliminate that friction by connecting prospective investors directly with regional stakeholders, signing strategic MoUs, and offering grounded guidance on market entry.

This collaborative model operates in both directions. While we help foreign executives enter the United States market, we also connect United States investors with key counterparts in Mexico, Europe, and Asia. Heightened geopolitical pressures and shifting trade policies create real operational friction for businesses, workers, and ultimately end-consumers through rising costs. Strong cross-border channels and targeted educational outreach allow us to protect the seamless flow of international commerce. This proactive work keeps local supply chains agile, mitigates rising operational costs, and ensures long-term stability for businesses on both sides of the border.

Q: A major hurdle for many Mexican manufacturers looking to integrate into North American supply chains is meeting US certifications and industry standards. What are the key strategies COSTEP deploys to help Mexican firms bridge this regulatory gap?

A: When foreign executives explore our region, COSTEP curates targeted immersion programs featuring subject-matter experts across real estate, legal counsel, site selection, and workforce development. We guide expanding companies through the proper sequence of market entry, preventing costly missteps.

A common mistake involves buying real estate or filing municipal permits on standard travel visas before establishing the correct corporate structure. Correcting that sequence after the fact creates massive administrative friction and expense. We advise companies to determine their corporate setup and immigration framework first, align with state and local economic incentives second, and only then acquire property.

Workforce readiness is equally critical. We immediately connect incoming manufacturers with regional universities and technical colleges. If a specialized training pathway does not yet exist for a new production process, our higher education partners build customized certification programs to ensure a qualified labor pool on day one.

Q: How do you collaborate with academia in the region?

A: For over 50 years, COSTEP and the Rio-South Texas Education and Community Development Foundation have focused on expanding educational opportunities across our region. In the late 1990s and early 2000s, a stark economic reality emerged: we were producing world-class graduates, but our local market lacked the advanced jobs to retain them. Historically, our primary regional export has not been goods; it has been talent.

Bringing advanced manufacturing and high-tech industries to Rio South Texas directly targets this brain drain. Graduates want to build their careers at home, but without high-value opportunities, they either relocate or settle for underemployment. Our mission centers on lifting the economic baseline for every resident in the corridor. Attracting sophisticated industrial operations creates high-paying careers locally, allowing our best and brightest to build their lives, raise their families, and drive innovation right here in Rio South Texas.

Q: What are the core operational milestones the organization must hit to fully execute its regional strategic plan? 

A: Our primary strategy focuses on bringing corporate decision-makers directly to Rio South Texas. International trade disruptions during the pandemic exposed the critical vulnerabilities of long, fragile overseas supply chains. Global manufacturers now recognize the operational risk of sourcing raw materials or assembling products half a world away from their end customers. Companies are not uprooting their primary global operations overnight; rather, they are evaluating how to build resilient, future-proof regional operations. We present our corridor as the ideal solution, positioning expanding manufacturers directly inside the North American supply chain.

This value proposition is generating significant momentum. Major global companies are choosing our region for strategic growth: Valeo recently selected McAllen for an automotive electronics manufacturing plant, Saronic Technologies selected Cameron County for its US$3.2 billion Port Alpha shipyard, and dynamic ventures in critical rare earth mineral processing, advanced refining, and maritime defense are actively evaluating sites across our corridor.

While local Economic Development Corporations excel at promoting their individual communities, COSTEP scales site visits across the entire binational region. Once foreign executives experience our infrastructure firsthand, meet regional stakeholders, and see how easily goods cross the border, the corridor sells itself. Direct site visits remain our most effective catalyst for converting global interest into long-term capital investment. 

The Council for South Texas Economic Progress (COSTEP) is a regional economic development organization that promotes the cross-border corridor encompassing seven counties in South Texas and 10 municipalities in Northern Tamaulipas, Mexico. Operating on a binational framework, the organization coordinates between public and private sectors to attract international manufacturing investment and optimize supply chains within the Rio South Texas region.
