It doesn't say it expires.

It says "mindestens haltbar bis", which is the German translation for "best before".

The manufacturer only guarantees the quality before that date. Afterwards, the anti-caking agent (Rieselhilfen) may not work so well, and the salt could be clumpy.

That's incredibly lucky, then. Imagine digging the salt out of the ground just before it expires, but still with enough time left to sell it.

I have read that water bottle contains expiry date, it is not for the water but to the plastic bottle which will start leaching chemicals after the expiry. I guess it is the same case here.

Even homeopathic medicine is required to have an expiration date, if only for legal compliance.

Homeopathic medicine should be required to actually have an effect, if only for legal compliance.

Haha. That is hilarious. 280 million years old, the preservative of preservatives. In many other countries (developing especially) they don't even pay attention to food expiration dates. We have eyes and a nose and they're really good at telling us when food shouldn't be eaten. I have a friend who is from Nigeria and was selling bags of rice at her shop. Food inspectors told her she had to throw the rice away because it had expired. She was devastated because she wasn't even used to thinking about rice expiring, especially not when it's just a few months old. Welcome to the West.
