We have reviewed the manufacturing procedures and raw materials used in the production of Dupont Corian® Solid Surface, Corian® Sintered and Corian® Quartz Surface (formally called Zodiaq®) kitchen countertops. These surfaces are certified kosher and are approved for use in kosher homes.


These countertops contain plastic and resin components. If they were used previously for non-kosher, or for use on Passover, one should consult a Rabbinic authority.
