I am buying a chemical in big quantity in large container of Approx 1 tonn. Repacking in drum of Aprox 25 Kg. with my labeling and MRP. 1. Do I need to take manufacturing license in Excise? 2. I am already having dealer and importer registration under excise. Can I amend the activity in the same license?
