Download Conflict Minerals Policy


Some of NS’ business operations likely constitute the manufacturing of products for sale, making it necessary for NS to investigate and report on the presence of any “conflict minerals” (in general, tungsten, tin, tantalum and/or gold) in those products.  NS suppliers should be aware of, and prepared to assist NS in carrying out, the NS conflict minerals policy.
