Sourcing and verification services for aerospace and defense buyers
Arzen is a sourcing and in-person verification intermediary. We don't manufacture and we don't hold inventory — we find, visit and verify Mexican CNC, tooling and structural shops, then stay involved through your first purchase order.
- Who it's for: U.S. procurement teams in aerospace, defense, aviation MRO and space systems.
- What we cover: supplier verification, CNC machining, tooling and fixtures, secondary structural components, nearshoring and first-order management.
- Where: verified shops in Querétaro and Nuevo León, Mexico.
- How to start: a short call about your part, tolerances, certifications and volume.
What we do for buyers
In-person supplier verification
We walk the shop floor, confirm equipment and tolerances against real parts, and cross-check references.
CNC machining sourcing
Precision machined parts from verified shops in Querétaro and Nuevo León.
Tooling and fixtures sourcing
Production, inspection and ground-support tooling from shops we've visited.
Secondary structural components
Brackets, supports and structural parts that are not flight-critical primes.
Nearshoring from Asia to Mexico
Move a part from an Asian supplier to a Mexican shop, with USMCA considerations raised early.
Quoting, sample and first order
Formal quotes, a physical sample before you commit, and a managed first purchase order.

|---|---|
| Supplier capability is self-reported and nobody has seen the shop floor | Supplier verification · Guide: how to vet a CNC supplier |
| Tariff exposure and long sea freight on parts sourced from Asia | Nearshoring · Guide: USMCA vs. China sourcing |
| You need tooling or fixtures without a long supplier-qualification cycle | Tooling and fixtures sourcing |
| You don't know what to put in an RFQ so quotes are comparable | Guide: RFQ checklist · Quoting and sample |
| The first order with a new supplier is the riskiest one | First-order management |
Who we work with
We stay deliberately narrow: tooling, fixtures and secondary structural components for aerospace OEMs and Tier 1/2 suppliers, defense manufacturing programs, aviation MRO, and space and satellite systems. We are not the right fit for flight-critical prime parts that require a 12–24 month certification cycle — if your part is one of those, we'll say so on the first call.
Where the work happens
Suppliers are located in Querétaro and Nuevo León, Mexico. Buyers can be anywhere in the United States.
Frequently asked questions
Does Arzen manufacture parts?
No. Arzen does not manufacture and does not hold inventory. We verify independent shops in Mexico and connect you with the ones that fit your part.
Which service should I start with?
Most buyers start with a short call. We discuss your part, tolerances, certifications and volume, and then recommend whether verification, sourcing or a managed first order is the right next step.
