However, some salt packaging might carry a "best by" date for a few reasons:
Regulatory Requirements: Many food products are required to have an expiration date, even if it's more about packaging guidelines than actual salt spoilage.
Mineral Integrity: Over long periods, especially if exposed to moisture, salt can clump or absorb other substances from the environment. A “best by” date ensures the salt remains in its intended state and quality during storage.
Additives: Some salts have anti-caking agents or other additives, which might break down over time, affecting the salt’s texture and appearance.
For pure Himalayan sea salt stored in a cool, dry environment, it should remain fresh indefinitely.
