Ground spice · Curcuma longa L.
Specification and grades
Turmeric is India's signature spice and the single largest volume line we move. We buy finger turmeric in the Erode, Nizamabad and Sangli markets, hold it against a declared curcumin band, and mill to the mesh your process needs. Because curcumin is the value driver, every lot is quoted against a stated minimum and confirmed on a third-party certificate of analysis before shipment.

Technical
Typical export specification
These are the parameters we contract against. Every consignment ships with a pre-shipment certificate of analysis from an NABL-accredited laboratory, and we will work to a tighter buyer specification where your process demands it.
Read this as indicative. Figures reflect standard Indian export practice and
common buyer specifications for this line. The binding specification is the one written into
your contract and confirmed on the pre-shipment COA.
