To promote the exports from India, the government has developed Export Promotion Councils, EPCs are made based on product wise.
You just need to google EPC for your product
Google
"Export Promotion Council for Agri Products" = APEDA : The Agricultural and Processed Food Products Export Development Authority
"Export Promotion Council for Plastic Products" = PLEXCONCIL : The Plastic Export Promotion Council
"Export Promotion Council for Hardware items" = EEPC : Engineering Export Promotion Council of India
You can google the council for your products & if you don't find official government export promotion council for your products then you can opt for FIEO Registration
"Export Promotion Council for Multiple Products" = FIEO : Federation of Indian Export Organization
Now if you become the member of such council you would be given Registration Cum Membership Certificate, RCMC
Suppose if I become the member of APEDA, I would be given APEDA RCMC Certificate
Suppose if I become the member of EEPC, I would be given EEPC RCMC Certificate
Suppose if I become the member of FIEO, I would be given FIEO RCMC Certificate
If your products are listed in Restricted Categories then you need RCMC else not but I suggest all my students and clients that you must register for RCMC Certificate for your relevant product.
