Reversal of ITC in case of Nil Rated Supply of Goods - Goods and Services Tax - GST

Dear Experts, We have imported Oats Grains from outside India and Sold the same domestically apart from some other taxable supplies. Since the said items falls under HSN 1004 in Schedule I (List of Nil Rated Goods), we have not charged GST on sale and accordingly declared as Nil rated supply in GST return. Is there any reversal of ITC required in such scenario? Please given reference if yes/no. Thank you
