The reconfiguration of global supply chains—accelerated by geopolitical tensions, pandemic disruptions, and rising logistics costs—has positioned Mexico at the center of a historic transformation. For decades, manufacturing companies viewed Asia as their primary production hub. Now, they see Mexico not just as a geographic alternative, but as a strategic platform to access the world’s largest market: North America.
However, this shift toward nearshoring involves more than just moving operations geographically—it’s a complete reengineering of the supply chain that requires a solid grasp of the regulatory environment in North America, particularly the United States-Mexico-Canada Agreement (USMCA).
To support companies navigating this transition, Prodensa has partnered with international trade experts to offer strategic insights into origin analysis and help businesses confidently address the complexities of the USMCA framework—especially relevant for those pursuing nearshoring or exploring shelter services in Mexico.
We would like to thank Adrián González, President of Global Alliance Solutions, for his valuable participation and collaboration. For companies pursuing turnkey operations in Mexico, understanding origin rules is a vital step in planning and executing a compliant cost-efficient setup.
The decision to relocate operations from China to Mexico is, at its core, a calculation of risk and opportunity. The opportunity is clear: proximity to the U.S. market, aligned time zones, competitive labor costs, and—most importantly—preferential access under USMCA. The often-overlooked risk lies in customs compliance.
Under a “Made in China” model, the equation was relatively simple: manufacture goods and export them to the U.S., paying Most Favored Nation (MFN) duties and, in many cases, punitive tariffs under Section 301. The complexity focused on logistics and direct import duties.
The answer to that question determines the financial viability of the entire nearshoring operation. A misstep in origin analysis could mean that a product assembled in Tijuana is treated, at the U.S. border, as if it were still made in China—nullifying the core benefit of USMCA.
To be considered “originating” and eligible for preferential treatment under USMCA, a product must comply with the Rules of Origin outlined in Chapter 4. While the rules vary significantly by product (as classified by HS codes), most rely on one of the following criteria:
1 Accurate HS classification of the final product and all imported components.
2 Analysis of the specific rule of origin linked to your HS code (whether it requires a tariff shift, RVC, or both).
3 Certification of origin—under USMCA, there is no official certificate format. The declaration can be made by the producer, exporter, or even importer, and may be included on invoices or other commercial documents as long as it contains the minimum data elements.
This is where many nearshoring strategies fail, as a common misconception is that final assembly in Mexico automatically grants Mexican origin. However, USMCA includes strict provisions to prevent this. The main issue lies in “simple assembly” or “insufficient production.” If the process performed in Mexico is minimal and does not result in substantial transformation, the product will not qualify—even if a tariff shift technically occurs.
A major financial risk in shifting operations is “double tariff taxation”:
1️⃣ Duties are paid in Mexico to import Chinese components (based on Mexico’s General Import Tariff).
2️⃣ Duties are paid again when the final product is exported to the U.S., if it does not qualify under USMCA.
Mexico’s IMMEX program allows companies to import raw materials or components temporarily, deferring or eliminating import duties and VAT, as long as the finished goods are exported within a set timeframe.
When simple assembly isn’t enough, the strategic solution is to increase value-added and substantial transformation within Mexico. This ensures USMCA compliance and strengthens your local supply chain.
Think of Mexico not as a low-cost assembly zone but as an advanced manufacturing hub. Consider these strategies:
The China-to-Mexico shift is not just logistical—it’s a strategic reinvention. Success isn’t measured by the opening of a new plant, but by the uninterrupted flow of tariff-free goods crossing the U.S. border every day.
To achieve this, your operation must be designed with compliance at its core. Optimizing your supply chain under USMCA requires:
By mastering these variables, your company won’t just mitigate transpacific supply chain risks—it will unlock the full potential of North America’s most powerful manufacturing platform. The opportunity is real, but only for those willing to do the work.
Understanding and applying USMCA rules of origin is essential for companies shifting from China to Mexico.
Simply relocating assembly is not enough—products must undergo qualifying transformation to earn tariff-free status.
IMMEX can significantly reduce import costs but must be paired with compliance to origin rules.
Value-added processes like SMT, machining, or yarn-forward textile strategies can help meet USMCA thresholds.
Non-compliance can lead to double tariffs, customs issues, and loss of nearshoring advantages.
Strategic planning must include HS code classification, origin analysis, and documentation from the beginning.
Nearshoring and turnkey operations in Mexico succeed when trade compliance is integrated into the relocation model.
Doing business in Mexico involves more than logistics—it requires expert handling of shelter services and trade programs.
Companies that get origin compliance right will unlock North America’s full manufacturing potential.
