About 1 year in the pantry, according to USDA FoodKeeper v128.
Cocoa and cocoa mixes are shelf-stable at room temperature: cool, dry pantry, sealed — refrigerating after opening is optional and mainly preserves quality. Refrigerating it mainly preserves quality rather than safety.
Look for: A rancid, paint-like, or musty smell; Clumping, or moisture in something that should be dry; Insects, webbing, or larvae in the package; Faded colour or a lost aroma. Those are the general signs for baking & cooking — USDA FoodKeeper v128 publishes no spoilage note for Cocoa and cocoa mixes specifically. Never taste something to test it — when in doubt, throw it out.
