USMCA and Manufacturing in Mexico: A Complete Guide for Foreign Manufacturers
The United States-Mexico-Canada Agreement (USMCA) is the trilateral trade agreement governing commerce among the United States, Mexico, and Canada. In effect since 2020, the USMCA replaced the North American Free Trade Agreement (NAFTA) and modernized the rules governing how foreign manufacturers establish and operate facilities in Mexico. For companies producing in Mexico for the North American market, USMCA defines the conditions for preferential tariff treatment, regional content thresholds, and labor and compliance obligations.
NAPS has supported foreign manufacturers operating in Mexico since 1991 through the original NAFTA implementation, the 2020 transition to USMCA, and every major shift in between. This guide walks you through the agreement’s key provisions, its impact on shelter manufacturing operations, and what is at stake in the upcoming July 2026 review.
What is the USMCA?
The United States-Mexico-Canada Agreement is a free trade agreement between the three signatory countries that went into effect on July 1, 2020. It replaced NAFTA, the 1994 agreement that had governed North American trade for more than two decades.
USMCA preserved the core principle of duty-free trade across most goods exchanged within the region, while introducing modernized rules on labor, digital trade, intellectual property, and rules of origin. In short, the foundation stayed the same, but the requirements got tighter and more sector-specific.
For foreign manufacturers, USMCA matters for one practical reason: it defines the conditions under which goods produced in Mexico may enter the United States and Canada free of tariffs. If your products meet USMCA requirements, you benefit from preferential tariff treatment. If they don’t, you face standard tariff rates that can meaningfully affect your cost competitiveness.
For a side-by-side comparison between the USMCA and its predecessor, see the NAPS guide to the changes from NAFTA to the USMCA.

Key USMCA Provisions for Manufacturers in Mexico
USMCA introduced several substantive changes that directly affect manufacturers operating in Mexico.
The provisions most likely to affect your operations fall into the following categories.
Rules of Origin
USMCA tightened the rules governing what proportion of a product’s content must originate within North America to qualify for preferential tariff treatment. Thresholds can vary significantly by product category. For example, vehicles and core automotive components are subject to the strictest requirements, while most other manufactured goods are subject to less stringent rules.
The automotive sector faces the highest regional content thresholds, along with additional requirements covering steel, aluminum, and labor. Most non-automotive sectors operate under lower thresholds, with category-specific rules tied to each product’s tariff classification. The exact threshold that applies to your product depends on its HS code, the calculation method used, and any sector-specific provisions in USMCA’s product-specific rules of origin.
Labor Value Content (LVC)
USMCA introduced a Labor Value Content requirement that applies primarily to the automotive sector. The rule requires that a defined percentage of a vehicle’s content be produced by workers earning above a specified hourly wage. A provision designed to address wage disparities between Mexican manufacturing labor and labor in the U.S. and Canada.
LVC compliance is verified through wage-and-hour records, and the specific percentages and wage thresholds vary by vehicle type. For manufacturers outside the automotive sector, LVC does not currently apply. However, enforcement standards, wage thresholds, and the scope of the rule are among the items expected to be discussed during the July 2026 review.
Steel & Aluminum Sourcing
USMCA established North American sourcing requirements for steel and aluminum used in qualifying products, particularly within the automotive supply chain. Vehicle producers must demonstrate that a defined share of their steel and aluminum purchases originates within the USMCA region in order for their finished vehicles to qualify for preferential tariff treatment.
For most non-automotive manufacturers, steel and aluminum sourcing rules apply only indirectly through the broader regional value content calculation rather than as a standalone requirement. As with other USMCA provisions, sourcing rules and verification standards are expected to be among the topics discussed during the July 2026 review.
Mexican Labor Reform Provisions
USMCA required Mexico to implement labor reforms that strengthen collective bargaining rights, union democracy, and worker protections. These reforms have been progressively rolled out since the agreement took effect and continue to shape the labor environment for manufacturers operating in Mexico today.
Digital Trade & Intellectual Property
USMCA modernized provisions covering digital trade, data flows, and intellectual property protection. Areas that NAFTA, drafted in the early 1990s, weren’t built to address.
USMCA Rules of Origin Explained
Rules of origin determine whether your product qualifies as originating within the USMCA region and is therefore eligible for preferential tariff treatment when crossing borders within North America. For manufacturers operating in Mexico, understanding and documenting compliance with rules of origin is essential to maintaining tariff-free access to the U.S. and Canadian markets.
Under USMCA, products must meet specific criteria to qualify as originating. These criteria vary by product type and may include:
- A minimum percentage of regional value content, calculated either by transaction value or net cost
- Specific tariff classification changes between non-originating inputs and the finished product
- For certain product categories, additional requirements covering specific components or processes
You are responsible for documenting compliance with the applicable rules of origin and for issuing or obtaining certifications of origin to claim preferential treatment. Failure to maintain proper documentation can result in retroactive tariff assessments, penalties, and loss of preferential access – none of which are easy to recover from after the fact.
A common misconception is that all manufacturers in Mexico face the same content requirements as the automotive sector. In practice, rules of origin are sector-specific, and many non-automotive product categories operate under less stringent thresholds. Documentation and certification obligations, however, still apply across the board.

The July 2026 USMCA Review
USMCA includes a built-in review mechanism that requires the three signatory countries to jointly affirm the agreement’s continuation. The first scheduled review takes place in July 2026, six years after the agreement entered into force.
If all three countries jointly affirm the USMCA in 2026, the agreement continues for another 16 years, with another review 6 years later. If they fail to reach a joint affirmation, the agreement enters a phase of annual reviews and ultimately expires in 2036, absent renewed consensus.
The 2026 review matters because it is the first real opportunity since 2020 for substantive modifications to the agreement. Issues likely to surface include:
- Enforcement and verification of Labor Value Content requirements
- Rules of origin specific to electric vehicles and battery components
- Treatment of non-North American content, particularly content originating in China
- Trade balance considerations and structural deficits
- Digital trade, data privacy, and cross-border data flows
The outcome of the 2026 review will determine the trade environment manufacturers operate in for the next decade. Whether the agreement is reaffirmed, modified, or allowed to drift toward expiration, NAPS will continue to monitor developments and translate any changes into the operational adjustments our clients need to remain compliant.

How USMCA Affects Shelter Manufacturing in Mexico
Shelter manufacturing in Mexico is an operating model in which a foreign manufacturer produces under the legal entity of a Mexican shelter provider. The shelter handles administrative, regulatory, and compliance functions, while you retain full control over production, equipment, and intellectual property.
Under USMCA, shelter operators play a central role in the day-to-day compliance work that determines whether your products qualify for preferential tariff treatment. The administrative functions handled within a shelter program include:
- Customs documentation, classification, and certification of origin
- Tracking of regional value content across components and finished goods
- Documentation supporting Labor Value Content compliance, where applicable
- IMMEX program compliance and reporting
- Audit readiness and response to customs reviews
- Monitoring of regulatory changes and translating them into operational adjustments
For manufacturers operating under a shelter model, USMCA compliance is built into the standard administrative framework, not an add-on, and not your team’s burden to figure out. This becomes particularly valuable during periods of regulatory change. As the July 2026 review approaches and any resulting modifications are implemented, shelter operators absorb the work of interpreting new rules, updating compliance documentation, and adjusting reporting workflows. Your team stays focused on production, not regulatory adaptation.
NAPS has supported manufacturers through every major shift in North American trade policy since 1991, including the original NAFTA implementation, the 2020 transition to USMCA, and the ongoing labor reforms required under the agreement. Whether you operate under a NAPS Mexico shelter corporation or under your own Mexican legal entity, NAPS provides the same high-quality compliance support in both scenarios.
USMCA Compliance Documentation Requirements
USMCA Compliance Documentation Requirements
Maintaining USMCA preferential treatment requires you to produce and retain documentation supporting your claims of originating status. The categories of documentation typically required include:
Documentation must be kept for at least five years and may be requested by customs authorities during audits or verifications. Inadequate documentation is one of the most common causes of retroactive tariff assessments. It’s also one of the areas where shelter operators add the most value, with systematic recordkeeping infrastructure that is already running, already audit-ready, and already built to USMCA’s specific format requirements.
