Pulverized Minerals Producer

NSSGA's Pulverized Minerals Division represents manufacturers of finely ground (minus 100 mesh) limestone and other industrial minerals. Members benefit through their affiliation with the NSSGA, which represents the construction aggregates industry.

As the most-respected organization of its kind, the Pulverized Minerals Division (PMD) of the National Stone, Sand & Gravel Association (NSSGA) has successfully represented the interests of its members for more than 40 years. The PMD, a full-service organization, promotes continuous improvement in the manufacturing process, product marketing, and sales of finely ground industrial mineral products. PMD also advances the market growth of the industry through product research. For more information, connect with us here.

If your company is already a Producer member and produces PMDs as well, NSSGA will waive the fee for PMD renewal.
