Driven by the growth of cross-border trade and the increasing opportunities brought about by nearshoring in North America, SIEM Business launched operations of its new subsidiary, SIEM Mountain, which will serve as the ultimate logistical and legal bridge between Mexico and the United States. 

“With SIEM Mountain, we don’t just offer a warehouse or a truck; we sell operational certainty and peace of mind to companies looking to relocate their supply chains without the frictions of border bureaucracy. We are the foreign trade office and comprehensive strategic partner that the Texas and Mexican markets needed,” said Sergio Islas Arias, CEO of the company.

These facilities are located in the border industrial zone at 12110 Esther Lama Drive, El Paso, Texas, with immediate access to I-10 and a proximity of six miles to the international bridges on the border with Mexico.

SIEM Mountain’s new facility boasts 100,000 sq ft (approximately 9,200 sq m) of optimized operating space for warehousing and cross-docking. It features a 24 ft clearance height and a total of 28 dock doors to ensure efficient loading and unloading. Additionally, there is a 200 ft truck yard with dedicated parking for 30 trailers simultaneously.

According to the U.S. Bureau of Transportation Statistics , freight trade between Mexico and the United States reached $86 billion in April 2026 alone, a 23.4% year-over-year increase, with El Paso consolidated as one of the top three truck freight ports with Mexico.

While the Ministry of Economy reported that during last May Mexican exports to the United States broke a historic record of 54.18 billion dollars, accumulating 558 billion dollars in the last 12 months and confirming Mexico as the main trading partner of the United States.

“El Paso has established itself as one of the three main cargo ports between Mexico and the United States, markets that exchange more than $558 million annually in Mexican exports to the United States,” Islas Arias explained.

In this regard, he explained that SIEM Mountain will have 360° coverage , integrating all links of the global and cross-border supply chain into a single entity.

• Customs Broker and Agent: Customs clearance with coverage throughout the United States. Specialists in permanent, temporary, and virtual imports and exports, IMMEX programs, accurate tariff classification, preventive foreign trade audits, and accredited inspection warehouses.
• Binational Land Transport: Full and partial cargo coverage, real-time monitoring and tracking, automatic arrival notifications, and customized reports.
• Free Trade Zone and Warehousing: Intelligent management and online inventory control for tax deferral and tax optimization.
• Ocean & Air Freight: Direct connection from the Texas border to major ports in Europe and Asia, offering ample weekly availability.

Similarly, SIEM Mountain incorporates cutting-edge technology to offer end-to-end visibility . Through its proprietary technological tools and platforms, it provides intelligent, real-time tracking of your goods, access to predictive data, and reports that safeguard your operations against any eventuality or customs inspection, ensuring transparency and security throughout the entire process.

This new platform begins operations by actively integrating into the business ecosystem of the southwestern United States, collaborating with local organizations such as the El Paso Chamber of Commerce and the Borderplex Alliance to catalyze new investments and accelerate the region’s business dynamics.

El cargo SIEM Business launches SIEM Mountain; seeks to strengthen the cross-border supply chain apareció primero en T21.

In an increasingly complex environment for foreign trade , SIEM Business is redefining its role in the logistics chain by opting for a comprehensive service model that seeks to resolve, in a single point, the operational needs of its clients.

Sergio Islas, the company’s director, explained to T21 that the firm has evolved from being an operator focused on specific processes to becoming a logistics partner that takes over virtually the entire operation, from origin to national distribution.

“Today, the goal is to do everything for the client. We want them to not have to coordinate five different suppliers, but rather find a complete solution with us,” he emphasized.

SIEM Business’s strategy focuses on strengthening its offering as a 3PL operator, integrating freight forwarding , customs clearance, transportation and distribution services.

Currently, the company consolidates cargo from Asia, mainly China and India, through a network of partners , with a strong specialization in maritime transport .

Once in Mexico, it handles customs clearance, tax payments and document management, and then takes care of the transfer and distribution.

One of its most representative cases is the operation for a retail chain , where it not only manages the import, but also carries out additional processes such as labeling and preparation of merchandise, delivering ready orders directly to each store nationwide.

“We ended up solving their problems. We no longer just import; now we also prepare the merchandise and get it ready for distribution,” Islas explained.

To support this model, the company has strengthened its infrastructure in key locations across the country . It currently has a presence in Ciudad Juárez, Manzanillo, Mexico City International Airport , and Tlaxcala, in addition to its own fleet of vehicles.

Added to this is the recent certification as an inspection unit, which will allow it to issue official opinions on labeling standards and commercial compliance, a key step to further integrate services into its offering.

“We no longer just handle logistics; now we can also verify regulatory compliance . This reduces intermediaries and waiting times for the client,” he emphasized.

Technology for end-to-end traceability

Another pillar of SIEM Business’s growth is technological development . The company has implemented its own tools and partnerships that allow it to offer complete visibility into operations.

On one hand, it uses artificial intelligence platforms that integrate and process information from multiple actors in the chain, suppliers, shipping companies, agents and carriers, to track cargo from its origin.

In addition, it developed an internal system that provides continuous tracking within the national territory, integrating GPS, electronic records, and billing into a single platform.

“Today, the customer can track their shipment virtually from origin to delivery. Furthermore, they have access to all their documents in one place,” Islas explained.

One of the most relevant innovations in its operating model has been to transfer critical processes to the country of origin, especially to minimize the logistical impact due to the current customs context in Mexico.

Through its partners in Asia, the company performs inspections, classification and validation of goods before shipment.

This approach has allowed them to reduce operating times from up to 120 days to windows of between 38 and 45 days, in addition to minimizing errors and costs associated with reprocessing at the destination.

“We prefer to do the work from the source. We arrive in Mexico with everything ready, which allows us to be much more efficient,” Islas emphasized.

Selective growth and new markets

The dynamic market has increased demand for comprehensive services, leading SIEM Business to receive a steady stream of new client requests. However, the company maintains a policy of selective growth.

“Not all clients are a good fit for us. We carefully analyze each transaction before integrating it, because this model requires commitment from both parties,” Islas stated.

In parallel, the company is advancing its international expansion with the opening of a marketing company in the United States, from where it will seek to connect the supply of US suppliers with Mexican companies, particularly in sectors such as auto parts and electrical components .

“We want to continue expanding our solutions. If the customer needs the product, we can also help them obtain it and bring it to them,” he added.

Amid a context of trade tensions, tariff uncertainty, and port congestion, the Strategic Bonded Enclosure (RFE) in Mexico is taking on new importance for companies seeking efficiency, flexibility, and certainty in their foreign trade operations.

With this vision, SIEM Business has implemented its new RFE in Tlaxcala, consolidating a strategic logistics hub in the heart of the country.

“This system has been in place in Mexico for years, but it hadn’t been fully exploited. Today, given the need for more flexible logistics solutions, the RFE is becoming crucial,” explained Sergio Islas, CEO of SIEM Business, in an interview.

This figure was created in 2002, one of the customs regimes provided for in article 90 of the Customs Law , where there are various possibilities and benefits for any type of merchandise, except for those indicated in Annex 29 of the General Rules of Foreign Trade (hydrocarbons).

Under this customs regime , merchandise of foreign, domestic, or nationalized origin can be received for various activities: storage or custody; minor manufacturing processes to ensure the merchandise complies with commercial regulations, such as labeling; and manufacturing, processing, or repair , among others, with very specific levels and security measures under the Customs Law.

One of the greatest advantages of this customs regime is that in all these activities , payment of foreign trade taxes can be deferred until the operator extracts the merchandise and decides its destination, allowing them to keep their inventory nearby without temporarily paying these taxes.

“The important thing is that it allows for safe, fiscal, and completely legal operations, but with an agility not found in traditional customs clearance,” Islas emphasized.

SIEM Business’s new RFE is located five minutes from Arco Norte, on a five-hectare site with 35,000 square meters of roof space.

Islas emphasized that there is a quick connection to the main land routes, Puebla International Airport, Felipe Ángeles International Airport (AIFA), Mexico City International Airport (AICM), and customs offices in Veracruz, Manzanillo, Lázaro Cárdenas, and even borders like Tijuana and Nuevo Laredo.

“The location is ideal for serving industries in the center of the country, such as the automotive, steel, and chemical industries. Many of these sectors face high logistics costs or downtime. Here we offer a complete ecosystem, from warehousing and labeling to customs clearance and transportation,” said the executive.

One of the lesser-known benefits of the RFE is that it allows foreign companies to operate in Mexico without legal representation . This has sparked interest from global companies, particularly those that used to distribute from the United States to Central and South America and now face higher tariff barriers.

“The RFE allows you to import, store, and redirect merchandise without committing large initial payments. For example, you can bring in 10 containers, store them, and pay taxes only on what you use. This translates into self-financing for companies,” Islas explained.

Although there are more than 60 RFE authorizations in the country, few are actively operating, and Tlaxcala thus becomes one of the first entities outside the Bajío region, the northern border, or the ports  to have an active and functioning facility.

Furthermore, RFEs can transfer merchandise between themselves without losing tax benefits, opening up the possibility of creating a more efficient logistics network.

“Merchandise can travel between facilities in different states without having to change regimes or pay taxes, which represents a great opportunity for industries with more complex supply chains,” Islas said.
