Expanding into Mexico requires a series of connected decisions about control, facilities, people, supply chains, contracts, tax, and customs. Each decision affects the others.
HIRO LAW advises US companies and their Mexican operating partners on selecting an operating model, documenting the key relationships, and coordinating the work required for launch. The work is principal-led and coordinated with tax, customs, employment, real estate, and other specialists as the project requires.
Whether the plan calls for a subsidiary, shelter, contract manufacturer, joint venture, or acquisition, the legal structure needs to reflect how the business will actually operate.
Choosing the Mexico Operating Model
The initial question is not simply which entity to form. It is how the business intends to operate, contract, employ people, import or export goods, occupy facilities, fund operations, and serve customers.
Depending on the business plan, the structure may involve:
- A wholly owned Mexican subsidiary with direct control over local operations.
- A shelter arrangement when the company wants to enter in phases or rely on an established local platform.
- Contract manufacturing, logistics, or shared-services relationships.
- A joint venture with a Mexican operating or commercial partner.
- An acquisition of an existing Mexican business or operating assets.
- A US holding structure coordinating ownership, financing, intellectual property, or customer contracts.
No model is universally preferable. The structure depends on the activities, assets, people, customer commitments, regulatory environment, tax and customs analysis, timeline, and degree of control the business requires.
Legal Workstreams for a Nearshoring Expansion
A coordinated Mexico expansion plan may need to address:
- Entity and governance: ownership, capitalization, board and officer authority, powers of attorney, reserved decisions, and intercompany relationships.
- Commercial contracts: customer, manufacturing, supply, services, distribution, logistics, licensing, and intercompany agreements.
- Facilities: industrial park terms, leases, built-to-suit arrangements, warehousing, utilities, permits, and launch dependencies.
- Trade and regulatory coordination: IMMEX, import and export, customs, foreign investment, sector-specific approvals, and tariff-related workstreams with the appropriate advisors.
- Workforce and compliance coordination: employment, labor, FCPA, sanctions, third-party diligence, and local operating controls with the appropriate specialists.
- Tax and cash movement coordination: transfer pricing, withholding, intercompany charges, funding, banking, and repatriation planning with tax and accounting advisors.
From Business Case to Operating Launch
Before commitments are signed
We map the operating model, parties, facilities, customer requirements, supply chain, funding, and timeline. This work identifies decisions that need to be made before a lease, customer commitment, or supplier agreement narrows the available options.
Before operations begin
We help establish the operating entities and authority structure, document the principal commercial and intercompany relationships, coordinate facility commitments, and organize the approvals and specialist work required for launch.
During the first 90 to 180 days
We use an implementation calendar and responsibility matrix to track contracts, approvals, filings, banking, facility readiness, customer onboarding, supplier terms, and operating controls. The plan distinguishes work that can be phased from issues that need to be resolved before operations begin.
Common Execution Gaps
- Forming an entity before the tax, customs, workforce, contracting, or facility model is understood.
- Signing customer, supplier, manufacturing, logistics, or facility agreements before the operating entity and authority structure are ready.
- Using contracts drafted for US operations without addressing requirements under Mexican law, local operating practices, or enforcement.
- Leaving board, officer, and signing authority unclear across US and Mexican entities.
- Failing to align intercompany agreements with transfer pricing, customs, cash movement, and the actual services or goods exchanged.
- Treating IMMEX, a shelter, contract manufacturing, or an owned entity as a shortcut rather than an operating model with specific tradeoffs.
- Allowing headquarters, local management, developers, suppliers, and outside advisors to work from different launch calendars.
The legal work needs to identify dependencies early, assign ownership, and remain tied to the operating timeline.
Representative Matters
Representative matters in this area include:
- Advised a US company establishing a new operating footprint in Mexico, including the execution timeline across advisors, operating responsibilities, and launch planning.
- Advised a Mexico-based company serving US customers on obtaining authorization under the IMMEX program, including foreign-investment and tax coordination and supplier and logistics terms.
- Created a cross-border authority matrix and approvals map for a US company with Mexico operations, including signing authority across entities and processes for related-party transactions.
Representative matters are illustrative and do not guarantee similar results.
When to Involve Counsel
Consider involving counsel while the operating model and launch sequence can still be changed, particularly before signing material customer, supplier, manufacturing, logistics, or facility commitments. Early coordination is also useful when US headquarters, Mexican operations, and specialist advisors are working from different assumptions or timelines.
Nearshoring is an operating project with legal dependencies. The structure, contracts, authority, and implementation calendar are interdependent and need to be designed together.
