Sourcing Silk Protein From India: 10 Questions to Ask (2026)

India has long been a centre of silk production, so it is a natural place to look for silk-derived ingredients. But a good source is not enough. What matters is how clearly a supplier can answer your questions.

This guide gives you ten questions to ask any supplier of sericin, silk peptide or silk powder, and what a good answer sounds like. We make these ingredients in Ramanagara, Karnataka, so we also answer each question for ourselves.

Why source silk protein from India?

India produces silk and has a long tradition of working with cocoons. For a buyer, that means access to raw material close to the processing, and a supplier who can tell you where it came from.

Location is not a quality guarantee, however. Treat it as the start of your questions.

Ten questions to ask a silk protein supplier

1. Where do the cocoons come from?

You want a region, how the cocoons are graded, and how they are cleaned. A supplier who cannot say is a supplier you cannot audit.

2. How is the ingredient made?

You do not need every detail, but you should get the main steps. Ours are on the process page.

3. What is the molecular weight range?

This decides how the ingredient behaves. It should be on the technical data sheet, as a range.

4. Which documents come with a sample?

Expect a technical data sheet, a certificate of analysis and a safety data sheet, plus the INCI name. Read our guide to TDS, COA, SDS and INCI.

5. Can you trace a batch?

Ask whether a batch number on the pack leads back to the raw material and the date of manufacture.

6. What are the microbial limits?

Protein ingredients need good microbial control. The data sheet should state the limits and the test results should appear on the certificate of analysis.

7. What is the shelf life, and how should it be stored?

Ask for both, in writing, and ask what happens after opening a pack.

8. What is your sample policy?

Ask how fast samples ship, which quantity you get, and whether the sample comes from a production batch.

9. What is the minimum order?

Ask for the minimum per grade and whether trial quantities exist.

10. How is it packed and shipped?

Ask about pack sizes, labelling, export paperwork and typical lead times to your country.

What a good answer looks like

• It is specific: a range, a date, a region.
• It is in writing.
• It arrives in days, not weeks.
• It matches what the documents say.
