PRICING NOTICE: Amendment to in-whs Rotterdam ferro-tungsten price specification

After a one-month consultation period, Fastmarkets MB has amended the specification of its ferro-tungsten basis 75% W, in-whs dup Rotterdam, $/kg W price, adding details on packaging.

According to market feedback, 1-tonne big bags are the most commonly accepted packaging by consumers of ferro-tungsten in Europe and are regularly traded in the spot market.

With effect from July 3, this amendment will introduce this detail on packaging within the specification. The change will avoid a potential price differential for different packaging of ferro-tungsten and avoid ranges too wide to compromise their utility for physical market applications or for tracking market trends.

The new specifications are listed below, with the amendment in italics:
