CHINA COMPONENT SOURCING · BUYER-SIDE SUPPORT
Find the right source. Know what you’re buying.
A supplier can quote a part. I help you compare the options, resolve technical questions and decide what needs checking before you buy.
START WITH YOUR TASK
What are you trying to resolve?
Start with one part or one question. There is no charge to discuss fit and agree a scope.
I have a part number.
Compare supply routes, traceability documents and the terms behind a quote.
Discuss the source02I need a Chinese alternative.
Separate a promising candidate from a part that only looks equivalent on paper.
Review an alternative03I know the application.
Turn operating conditions into a brief suppliers can answer and engineers can review.
