A commodity account cannot be opened without opening an equity account. See Can a commodity account be opened without opening an equity trading and demat account?

Did you know?

• Except for the equity delivery brokerage charge, the brokerage for a HUF account is the same as an individual account. However, account opening charges are higher due to higher compliance costs.
• A brokerage of ₹40 per executed order will be charged instead of ₹20 while placing an F&O order if the Zerodha account has a negative balance.
