SHANGHAI, Sep 23 (SMM) - SMM research showed that the bonded zone inventory stood at 5,480 mt this week. The inventory of nickel briquette was 2,250 mt, and that of nickel plate was 3,230 mt. At present, the downstream and terminals markets are recovering. The inventory decreased slightly because the steel mills are expected to resume the production in September, which pushed up the demand for pure nickel despite the small consumption.  In addition, before the National Day holiday, downstream companies were busy in restocking, thus the bonded zone inventory of nickel plates and nickel briquettes changed to varying degrees.
