Curcumin 95% is the core high-spec lane
For supplement and cosmetic-adjacent buyers, Curcumin 95% by HPLC is often the first grade to verify with COA and chromatogram support.

Other forms may fit different applications
Turmeric extract 10:1, water-soluble curcumin, curcumin granules and tetrahydrocurcumin can serve different formulation needs.

RFQ should include assay and end use
Buyers should provide target percentage, assay method, quantity, application and market so supplier matching can avoid unsuitable grades.
