Headquartered in Paris, Tenn., H.C. Spinks Clay Company is a leading producer of dry and wet-processed clay minerals. We've remained at the forefront of the industry by continually innovating our practices and by demanding the highest standards of quality.

And to maintain these standards, we established a strict guideline for our business, Statistical Process Control, not by government or industry mandate but because we demand it of ourselves. Specifically, Statistical Process Control is our policy of assuring that the clay we produce meets the highest standards of quality, which we accomplish by administering constant evaluation and control at every level of operation.
