Manufacturing in México made simple
For many North American companies, expanding manufacturing into México offers significant advantages —but navigating regulations, labor laws, logistics, and compliance can be complex.
5C Assemblex provides a proven solution through our Shelter Program that allows companies to operate efficiently in México while we manage the operational framework.
A Shelter Program allows foreign companies to operate manufacturing or assembly facilities in México without the need to establish and manage a Mexican legal entity.
Under this model, the shelter provider assumes responsibility for administrative, legal, and regulatory functions, while the client focuses on production, quality, and operational control.
This structure reduces risk, shortens startup timelines, and simplifies compliance with Mexican labor, customs, and tax requirements.
Through our shelter program we manage:
• Import and export compliance
• Human resources and payroll
• Regulatory and labor compliance
• Accounting and tax obligations
• Facility management and operational support


Our approach is built around clarity, flexibility, and execution.
We work with each client to define the right structure based on their operational needs, production requirements, and level of involvement. Rather than applying rigid programs, we adapt our support to match how each operation needs to function.
Whether the need is a full shelter environment, contract manufacturing support, or fulfillment services, our focus is on creating a structure that is practical to operate, transparent in cost, and stable over time.
