Chinese chemistry sourcing concierge
Concierge sourcing across 5 industrial-cluster cities and 5 categories: 24h BD acknowledgement, 48–72h with three comparative quotes, per-batch COA.
Named partner network
Below are the partners ChemExact has signed direct agreements with. Their branded product pages render per-batch COA, SDS and spectra. We do not publish every supplier we reach during a reverse-sourcing request — those facilities sit in our verified network roster and surface only when a buyer's RFQ matches.
Long-term contractual partner. ChemExact holds inspection rights on every shipment and publishes per-batch COA on the product page. Top of every buyer-search ranking.
