Why the work left — and why it wasn't just labor cost
The standard story says manufacturing chased cheap labor. For machined parts, that story is half wrong. A CNC machine costs the same in Ohio as in Shenzhen, and labor is a shrinking slice of a machined part's cost. What actually pulled work overseas was speed of iteration: a hardware team in Shenzhen can get a prototype machined, revised, and re-machined twice in the time an American team waits for its first round of quotes.
Engineers prototype where iteration is fast — and production follows the prototype. That's the mechanism. Which means reshoring isn't won with tariffs or patriotism. It's won by making the American loop fast again. That is, literally, why Praetore exists.
The landed-cost math nobody runs
The unit price on an overseas quote is not what the part costs you. Add freight (and its volatility), duties and tariff exposure, 6–10 weeks of inventory carrying cost, the cash tied up in larger minimum orders, quality escapes discovered only after a boat ride, and the engineering hours spent managing a vendor thirteen time zones away. On low-to-mid volumes and precision work, the American part is very often cheaper — landed — before you count a single strategic benefit.
Rule of thumb:
Qty < 1,000, tolerance < ±0.005", or revision likely → domestic usually wins landed.
Qty > 10,000, stable design, loose tolerance → overseas still often wins on price alone.
In between → run the numbers; the answer flips on freight and iteration count.
What you buy that never shows up on the invoice
- Iteration speed. A design revision that takes 5 days instead of 6 weeks compounds across a development cycle into shipping your product a quarter earlier.
- IP that stays yours. Your CAD never leaves U.S. jurisdiction, protected by contracts courts here will actually enforce.
- A supply chain you can visit. When something goes wrong at 2 a.m., "the shop is a phone call and a flight away" is a different product than "the factory reopens after the holiday."
- Eligibility. Defense, aerospace, medical, and government work increasingly requires domestic sourcing. Made-in-USA is a market-access key, not a sticker.
The playbook: reshore in three moves, not one leap
- 01Move prototyping first. Zero risk — you need speed most during development anyway, and you'll re-validate suppliers before production ever moves.
- 02Dual-source the critical parts. Qualify a domestic source for the components that would halt your line if a container went missing. Pay a little more for the insurance until volumes justify the switch.
- 03Move production when the math flips. Design revisions, tariff changes, or quality escapes will flip it sooner than you think — and when they do, you'll already have a qualified American supply chain, not a scramble.
