Need the list of raw material suppliers, key partners?

For a project i'm doing, i need the list of raw material suppliers, key partners to top notch companies such as Nikon, Samsung, Canon, etc. Can someone please tell me where i can get such information.

Just go to www.alibaba.com or indiamart.com or globalsources.com

I would suggest you to check esources.co.uk, UK's trade portal. It's a wholesale directory and is the best source to guide you for sourcing suppliers from all parts of the world! You can find wholesale suppliers, dropshippers and distributors here.
