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.
Request a consultationWe 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
China-origin tariff exposure (rates change often — verify current duties), 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.
| Factor | Sourcing from Asia | Sourcing through Arzen |
|---|---|---|
| Tariff exposure | China-origin tariffs apply (rates change often) | No China-origin tariffs; USMCA preference depends on origin rules |
| Freight lead time | Weeks by sea | Overland by truck |
| Supplier verification | Self-reported, unverified | 100% verified in person |
| Certification cycle | 12–24 months typical | Matched to pre-verified shops |
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.
Aerospace OEM & Tier 1/2
Tooling and secondary structural components for prime and sub-tier manufacturers.
Defense & military systems
Precision tooling and structural parts supporting defense manufacturing programs.
Aviation MRO
Replacement tooling and structural components for maintenance, repair and overhaul operations.
Space & satellite systems
Ground support tooling and structural components for space and satellite manufacturers.
What we do for aerospace and defense buyers.
Verification comes first; sourcing, quoting and the first order follow from it.
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
Production, inspection and ground-support tooling from shops we've visited.
Structural components
Brackets, supports and other secondary structural parts — not flight-critical primes.
Nearshoring (USMCA)
Move a part from an Asian supplier to a Mexican shop, with USMCA questions raised early.
Quoting and first order
Formal quotes, a physical sample before you commit, and a managed first order.
Querétaro and Nuevo León, for buyers across the U.S.
We visit supplier facilities in two Mexican states and serve procurement teams anywhere in the United States.
From first call to a running purchase order.
Diagnosis
A short call to understand your part, tolerances, certifications and volume.
Verified suppliers
We present pre-verified CNC and tooling shops in Querétaro / Nuevo León matched to your spec.
Quote & sample
Formal quoting and a physical sample part before you commit to a production run.
First order
We manage the first purchase order end to end so the handoff to your supply chain is clean.
"A supplier profile can say anything. We've walked the floor to find out what's true."
Quoting platforms
Self-reported capabilities and instant quotes. No one's seen the shop floor or met the owner.
Independent brokers
Personal relationships, but no repeatable process, no documented verification, no scale.
Arzen
In-person verification, a documented process, and one accountable point of contact.
What buyers ask before their first order.
What does Arzen actually verify before recommending a supplier?
We visit the shop floor in person, confirm the equipment list against real parts in production, check documented tolerances and capacity, and cross-reference the shop's track record with its existing clients. That verification is the entire service — sourcing and quoting follow from it.
Is sourcing from Querétaro or Nuevo León USMCA-qualifying?
Yes. Suppliers in our network are located in Querétaro and Nuevo León, Mexico, and sourcing through them avoids the tariff exposure associated with parts sourced from China, while cutting freight time from weeks by sea to hours by truck across the border.
What industries and part types does Arzen focus on?
We stay deliberately narrow: tooling, fixtures and secondary structural components for aerospace OEMs, Tier 1/2 suppliers, defense manufacturing programs, aviation MRO and space/satellite systems — not flight-critical primes requiring a 12–24 month certification cycle.
How much does it cost to work with Arzen?
Consulting engagements start at a fixed fee, discussed on your initial call once we understand your part, tolerances and volume. There is no cost to submit an inquiry.
How is Arzen different from a sourcing marketplace or broker?
Marketplaces rely on self-reported capabilities with no one having seen the shop floor. Independent brokers offer personal relationships but no documented, repeatable verification process. Arzen combines in-person verification, a documented process, and one accountable point of contact through your first purchase order.
What happens after I request a consultation?
Our team follows up within 1 business day to schedule a short call about your part, tolerances, certifications and volume. From there we present pre-verified shops matched to your spec, manage formal quoting and a physical sample part, and stay involved through your first production order.
