After a two month consultation period, Metal Bulletin has decided to stop assessing single-number base metals premiums after feedback from market participants and exchanges said that these numbers are not widely used by the industry, who prefer to use the low-high premium assessments, in particular the midpoint of the ranges.

The single-number base metal premiums that will stop being priced are as follows:

    • Aluminium P1020A premium, cif Shanghai, spot, $/tonne
    • Aluminium P1020A premium, cif MKP (Main Korean Ports), duty-free, spot, $/tonne
    • Aluminium P1020A premium, in-warehouse Rotterdam, duty-unpaid, spot, $/tonne 
    • Copper premium, Grade A cathode, in-warehouse Shanghai, spot, $/tonne 
    • Copper premium, Grade A cathode, cif Shanghai, spot, $/tonne 
    • Copper premium, Grade A cathode, cif South Korea, spot, $/tonne 
    • Copper premium, Grade A cathode, cif Leghorn (Italy), spot, $/tonne 
    • Nickel premium, 99.80% purity full plate, in-warehouse Shanghai, spot, $/tonne 
    • Nickel premium, 99.80% purity full plate, cif Shanghai, spot, $/tonne 
    • Zinc premium, 99.995% purity ingot, in-warehouse Shanghai, spot, $/tonne 
    • Zinc premium, 99.995% purity ingot, in-warehouse Singapore, spot, $/tonne
