Hi Biswarup,Thanks for asking the most trending question on dog food. We would like to inform that Dog Food should be taxed under HSN Code 23091000 at Nil GST. Earlier Dog food was taxed at 12.5% in most of the state of India and was exempt in some states i.e. Madhya Pradesh, Goa.Now Under GST regime Dog Food has to be taxed @ Nil. The most canine food companies are saying it will be taxed at 18% and also approaching GST Council to fix at the same but some are selling at Nil as per GST rate list issued by GST Council on dated. 18th May 2017.So It means Dog Food price will be little-gone up if the council fix at 18% which was earlier 12.5%.
