Decision to launch of antimony trioxide 99.5% Sb2O3 min, exw China price assessment: pricing notice

Following a one-month consultation that ended on April 10, Fastmarkets has determined that current circumstances make the launch of antimony trioxide 99.5% Sb2O3 min, exw China price assessment viable. The new price expands Fastmarkets’ coverage of the antimony market and expands its existing suite of assessments. The addition of a China domestic price offers market participants a new indicator reflecting the distinct conditions of the Chinese market, especially following the introduction of antimony export controls that have heightened the importance of transparency in domestic pricing.

The first price assessment will take place on April 17, 2026.
