Proposal to amend frequency of Chinese magnesia prices: pricing notice

Fastmarkets proposes to amend the frequency of the publication of its price assessment for MB-MAG-0005 Magnesia, dead burned, 97.5% MgO, lump, fob China, MB-MAG-0002 Magnesia, dead burned, 90% MgO, lump, fob China, MB-MAG-0009 Magnesia, fused, 97% MgO, Ca:Si 2:1, lump, fob China, and MB-MAG-0007 Magnesia, fused, 98% MgO, lump, fob China, to monthly from weekly.
