For reference, this is the legal definition in France (which still allows for some shitty chocolate BTW) :
Chocolat :
a) Désigne le produit obtenu à partir de produits de cacao et de sucres contenant, sous réserve du point b, pas moins de 35 % de matière sèche totale de cacao, dont pas moins de 18 % de beurre de cacao et pas moins de 14 % de cacao sec dégraissé.
Rough translation:
Chocolate is the product obtained from cocoa and sugars which shall contain no less (although see point b) than 35% of dry cocoa solids including 18% cocoa butter and 14% dry degreased cocoa.
Point b covers specialty chocolates, such as guanduja, etc.
