Find the factory
behind the spec.
Manufacturer discovery for industrial buyers. Search China by product, standard, material, or process—and see what the public evidence does and does not support.
Industrial sourcing,
made legible.
Most directories begin with supplier promotion. We begin with the buyer's specification, then organize public evidence around the questions that matter before outreach.
Accuracy before catalogue size.
All 100 discovery leads are searchable, but review status stays visible. Only seven expanded profiles have completed the current human source-review pass; the remaining leads are research starting points, not recommendations.
Know the part?
Start from a DIN, ISO, ASTM standard or model number.
Open product finder ↗02 / CAPABILITYKnow the process?
Explore fasteners, machining, stamping, casting, and tooling.
Browse manufacturing ↗03 / SOURCINGNeed a shortlist?
Describe the requirement privately for evidence-led review.
Build a sourcing request ↗Built to earn trust,
not borrow it.
Every published profile should help a careful buyer ask better questions. We separate what a source says, what our review supports, and what remains unknown.
“Would a cautious buyer understand both the evidence and its limits?”
That is the question behind every publication decision. AI may help organize public information; a human review remains required before a manufacturer profile is published.
Sources stay visible
Accepted evidence is linked to its public origin and review date.
Unknowns stay honest
Capacity, ownership, MOQ, certificates, or export readiness are marked open until supported.
Corrections stay open
Companies and buyers can challenge a record with supporting public information.
