Stop gambling on unverified CNC suppliers.
We hand your sourcing team a short list of Mexico-based CNC, tooling and structural suppliers we've already walked the floor of, verified capacity on, and would stake our name on. USMCA-qualifying. No China exposure.
The verification layer your procurement team doesn't have time to build.
A procurement director can find a hundred CNC shops in a Google search. What that search can't tell you is whether any of them can actually hold your tolerance, hit your date, and answer the phone when something goes wrong.
We close that gap by doing the unglamorous work before you ever see a name: walking the shop floor, checking the equipment list against real parts, sitting across the table from the owner. That verification work is the entire service. Sourcing, quoting and order management follow from it.
- Trusted expert. We speak in exact numbers: tariffs, lead times, tolerances. Never empty adjectives.
- Human relationship. We've already done the hard verification work so you don't have to.
- Industrial precision. The same rigor we ask of every supplier shows up in how we run the business.
Arzen is a sourcing and verification intermediary for U.S. procurement teams. We don't manufacture and we don't hold inventory. We connect you directly with pre-verified CNC, tooling and structural suppliers in Querétaro and Nuevo León, and stay involved through your first purchase order.
Diagnosis & matching
Tell us your part spec, tolerances and volume. We match you against shops we've already walked, not a database of self-reported listings.
Quoting & sample
Formal quoting and a physical sample part before you commit to a production run. No blind orders.
First order management
We manage the first purchase order end to end so the handoff into your normal supply chain process is clean.
- In-person visit. No shop enters the directory without a physical visit.
- Verified capacity. Equipment, tolerances and volume confirmed on site.
- Cross-checked references. We validate track record with the shop's other clients.
The floor every part has to earn.
Sourcing from Asia costs more than the invoice.
Tariffs
Effective tariff exposure on parts sourced from China, on top of freight and customs handling.
Time
Typical lead time by sea from Asia, versus days by truck from a USMCA-qualifying supplier.
Risk
An unverified supplier found on a marketplace, with no one who has walked the shop floor.
Aerospace and defense, across every U.S. state we ship to.
We stay deliberately narrow: tooling, fixtures and secondary structural components, not flight-critical primes. That focus is what lets us move fast without a 12 to 24 month certification cycle.
