What you’ll learn
-Why CNC quotes from China can vary wildly for the same CAD and drawing
-The 3 supplier tiers in China and which tier is best for your job
-How machine choice and internal hourly rates quietly change your price and risk
-How to use price only to remove outliers and focus on the true market cluster
-How to read factory profiles like an engineer (machines, QA, proof of similar work)
-The exact questions that expose weak “yes can” suppliers fast
-How to de-risk with a small trial order before scaling volume

Before you switch a CNC job to a new China supplier, confirm:
-They name critical dimensions and how they will measure them
-They explain fixturing and setups for tricky features
-They call out the biggest machining risk in your design
-They show inspection tools and a QA process that matches your risk level
-They can control finishing (masking, partners, post-finish re-check)
-You run a trial order (10 to 20 pcs) and verify dimensions, finish, packaging, labeling
