The amendments will take place immediately, following feedback from the industry after an extended consultation and Fastmarkets’ own analysis of market dynamics and evolving practices and standards.

Vale rounds will be clarified into three distinct specifications under Fastmarkets’ specified cobalt metal brands.

  • Vale Port Colborne rounds will be put under alloy grade.
  • Vale Long Harbour alloy grade rounds (99.9% cobalt) will be put under alloy grade.
