Refer to Issue ID 116174 dated 30.3.20 . First go through reply at serial no.12 dated 5.4.20 posted by Sh.Sanjay Malhotra, Sir. Thereafter, read my views. It will be convenient for you to grasp the complicated classification.
If raw material/ingredient, namely, ethanol (alcohal) pre-dominates in the final product , namely, hand sanitizer it is classified under Chapter/Heading No. 3004 of Tariff Act attracting rate of tax @12%.. For your further information , Chapter/Heading No.3402 attracts 18% and 3808 attracts 18%. So the classification depends upon which raw material/ingredients predominates and for what purpose is being used. There are different types sanitizers with different purpose, function and usages. Hence different classifications for sanitizer. In your product, ethanol (alcohol) predominates, so your product is most appropriately classifiable under Chapter/Heading No.3004.
