IVEMSA vs Tetakawi: How Two Mexico Shelter Providers Compare

IVEMSA and Tetakawi are both full-service shelter operators with roughly four decades behind them, and the choice between them turns first on geography. IVEMSA runs from Mexicali across Baja, Sonora, the Bajio, and Monterrey on a single consolidated fee. Tetakawi runs from Tucson and owns the industrial parks its clients occupy in Sonora, Saltillo, and Mexico's interior. Fee structure and your entity plans decide the rest.

Best known for	Deep Baja roots, one all-in fee, and standalone managed services for companies that already hold their own entity	Owning the buildings, and being first to reach Mexico's interior

Both are long-established firms. Roughly 25 to 30 shelter providers operate in Mexico as of 2026, and most of the established names have been at it 30 years or more. The differences below are differences of shape.

What is each firm built around?

IVEMSA

IVEMSA was founded in 1982 and operates from Mexicali, with a US office in San Diego. Baja California is its home ground, and it has extended from there into Sonora, the Bajio, and Monterrey. Clients manufacture under IVEMSA's entity while the firm carries the administrative layer, billed as a single consolidated fee. That structure makes the monthly number easy to model and easy to compare year over year.

The second thing worth knowing about IVEMSA is that it offers standalone managed services for companies that already hold their own Mexican entity. For a manufacturer that expects to incorporate at some point, that means the administrative relationship can continue after the entity exists.

Tetakawi

Tetakawi was founded in 1986 as The Offshore Group and operates from Tucson, Arizona. It owns the industrial parks its clients occupy, with sites in Sonora at Empalme and Guaymas, in Saltillo, and in Mexico's interior. It is known as the first shelter to reach Mexico's interior.

Because the building and the administration come from the same firm, site selection and the shelter agreement get settled in one conversation, on one timeline, with one counterparty. For a first Mexican operation with a short runway, that is a real simplification.

Which one fits your operation?

Three questions carry most of the weight.

1. Where does the operation belong? This is usually the decisive one. If your suppliers, your customers' plants, and your crossing point sit in Baja, IVEMSA's four decades based in Mexicali are the relevant asset. If the operation belongs in Saltillo or deeper into the interior, that is Tetakawi's map. Sonora is where the two genuinely overlap, and in Sonora the question moves on to the next two. Location also drives labor availability, wage levels, and logistics cost, which together outweigh most fee differences. The best states to manufacture in Mexico breakdown is a useful second read here.

2. How do you want to be billed, and what is inside the number? IVEMSA quotes one consolidated fee for the shelter service. Tetakawi's model includes the building itself. Those two quotes are not comparable until you fix the boundary. Ask each firm for a total landed monthly cost per employee at your projected headcount, and state explicitly whether real estate, utilities, and equipment are inside or outside that figure. Market shelter management fees generally run $350 to $550 per employee per month for entity management, HR, payroll, and compliance, which gives you a sanity check on the administrative portion. Run both quotes against your own headcount and wage assumptions in the Mexico manufacturing cost calculator.

3. Might you hold your own entity later? Worth answering honestly at the start, because it changes what you negotiate today. The practical cost crossover to your own entity lands around 500 to 1,000 employees for most manufacturers, and selling into Mexico's domestic market requires your own entity regardless of size, since a shelter's IMMEX permit is export-oriented. If either of those is on your horizon, ask each provider in writing how a transition works: what happens to the lease, the employees, the equipment, the customs registrations, and the IMMEX permit. IVEMSA's standalone managed services line is directly relevant to that question. The full analysis sits in shelter or your own entity.

What if the operation is going to be yours outright?

Some manufacturers know from the first meeting that the Mexican operation will be held in their own name: the entity, the IMMEX certification, the incentives, the banking relationships, and the land or the lease. That path takes 6 to 12 months and it produces an asset on your own balance sheet, with the freedom to sell into the domestic market and to negotiate directly with the states that want the plant.

That is the work Calder & Vale does. A Canadian principal resident in Mexico City, direct relationships with the SEDECO economic development ministries in Mexico City, Estado de Mexico, and Nuevo Leon, a Mexican legal partner in practice four decades with partners ranked by Chambers and The Legal 500 in corporate and M&A and in arbitration, and standing in COMCE, CanCham, and AmCham. A real multi-state competition for your site and your incentives, run in your name, with the entity built to hold what you win.

The A.1 Diagnostic is where that starts: your numbers, your product, your timeline, and a clear read on which path earns its keep.

The bottom line

IVEMSA and Tetakawi are both credible, four-decade shelter operators, and most manufacturers will find the choice made for them by geography. Baja points to IVEMSA. Saltillo and the interior point to Tetakawi. Sonora is a genuine contest, decided by what is inside the fee and whether the building comes from the same firm. Add one more question before you sign either agreement: whether the operation is likely to be yours outright within a few years, and what the transition looks like when it is. Answer that early and both conversations get simpler.
