Buyers can see exactly how every profile was built
Public records, AI extraction and a confidence score on every field — held back from indexing until it clears human review.
Source transparency
Every profile links to its public sources and shows a confidence score.
Human-reviewed
Records below the 80% confidence threshold are held for manual review.
No cloaking
Public fields render identically for users and crawlers.
Real buyer demand
De-identified buyer requests you can quote on, no log-in required to browse.
Independent platform
We don't buy, sell, or handle payments. Buyers and suppliers deal directly.
Procurement Requests
Start from the 14 chemical categories buyers search for most
Level-1 categories come from the platform taxonomy; each tab lists the CAS-verified products published under it and links to the suppliers currently indexed for that product.

Counted live from the database — these are actual records, not sample figures. Supplier counts use the same rule as the public directory.
Supplier verification & on-site audits
On-site factory audits, reviewed third-party reports (BSCI, ISO 9001) and self-assessments — each shown as a distinct badge on the supplier profile.
Pre-shipment & product inspection
Four inspection types — pre-shipment, loading supervision, product / lab testing and sample verification.
Careers & partnerships
Hiring verification auditors and growing our partner network across sourcing, logistics and testing.
