Setting up a nut packaging unit requires a Food License from the FSSAI, as dry fruits and nuts are classified as processed foods. Depending on your business's annual turnover, you'll need either a Basic FSSAI Registration (for turnovers of INR 12 lakh and above), a State FSSAI license (for mid-sized companies with turnovers of INR 12 to 20 crores), or a Central FSSAI license.
