My company has CE Certificate for G603, G654, G684, HN Black, Slate, China marble, Red Porphyry.

CE certificate enables products to be comercially used in European Economic Area , EEA. To market any product within EEA, it should have CE Marking (previously CE mark).

CE stands for nothing perticular. Unofficially it means "European Conformity" (in French, Conformete' Europe'enne).
