I advice you to search HSN code.
I have found one I do not know which electroplating machine you manufacturing.
But one sample is here:
85433000 : ELECTRICAL MACHINES AND APPARATUS HAVING INDIVIDUAL FUNCTIONS, NOT SPECIFIED OR INCLUDED ELSEWHERE IN THIS CHAPTER MACHINES AND APPARATUS FOR ELECTROPLATING, ELECTROLYSIS OR ELECTROPHORESIS
