Turmeric (Curcuma longa) is one of India’s largest botanical exports, and buyers order it in two very different forms: the raw spice powder and a standardised curcumin extract. They are not interchangeable, and the price gap between them is large. This guide covers the grades, the curcumin question, the documentation and the forms buyers actually specify.
Raw powder or curcumin extract?
Raw turmeric powder is the milled spice, used across food, beverage and traditional preparations. Curcumin extract is concentrated and standardised to a high curcuminoid level for the supplement and nutraceutical trade. The rule is simple: if your purchase specification names a curcumin percentage, you need the extract; if it names the spice, you need the powder.
What curcumin content is available?
Our curcumin extract is standardised to 95% curcuminoids by HPLC, with curcumin I at 70 to 80% of the total. Raw and intermediate powder grades carry the naturally occurring curcuminoid level. Because it varies by crop and grade, the COA for the lot is the figure that matters, not a headline number.

Curcumin or curcuminoids?
The two terms are often used loosely, and it costs buyers money. Curcuminoids are the group of three related compounds; curcumin, or curcumin I, is the principal one. A 95% curcuminoid extract means 95% total curcuminoids, of which curcumin I is 70 to 80%. Tell us which figure your formulation is written against and the COA will confirm it.
How is quality verified?
Every lot ships with a Certificate of Analysis: curcuminoid assay by HPLC, moisture, ash, heavy metals and microbial load, from a GMP facility. Organic documentation is available on request. A serious buyer checks the assay and the contaminant panel against their own specification before shipment.

Frequently asked questions
Turmeric powder or curcumin extract: which do I need?
Raw turmeric powder (Curcuma longa) is the whole spice, used in food, beverage and traditional formulations. Curcumin extract is standardised to a high curcuminoid level for supplements and nutraceuticals. If your specification names a curcumin percentage, you need the extract; if it names the spice, you need the powder. We supply both.
What curcumin content is available?
Curcuminoids are standardised to 95% by HPLC in the extract grade, with curcumin I at 70 to 80% of the total. Raw and intermediate powder grades carry the naturally occurring level. The exact assay for your lot is stated on the COA.
What is the difference between curcumin and curcuminoids?
Curcuminoids are the group of three related compounds in turmeric; curcumin (curcumin I) is the main one. A 95% curcuminoid extract means 95% total curcuminoids, of which curcumin I is 70 to 80%. Specify which figure your formulation needs so the COA can confirm it.
What documentation comes with bulk turmeric and curcumin extract?
Every lot ships with a Certificate of Analysis covering the curcuminoid assay by HPLC, moisture, ash, heavy metals and microbial load, from a GMP facility. Organic documentation is available on request.
