12 months in a cool, dry pantry.
How can I tell if sunflower seeds have gone bad?
Throw them out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
