SANTA BARBARA, CA -- World Minerals Inc., a member of Imerys, will raise prices on all products effective Jan. 1, 2010. Price increases will average three percent in North America and may be higher in some cases to correlate with specific products and market conditions.
The price increase is necessary to support further investment in manufacturing and quality systems; it will affect all diatomite, perlite and silicate products, as contracts allow. The energy surcharge will also remain in effect.
