Doesn't that have to do with the container?
Yep, the plastic dissolves
So now the salt is full of microplastics? Well, so am I. Come on in and join the rest.

Gooble Gobble!
On salt?
It depolymerizes on water, but salt is extremely hydrophilic and stops that process down.
Table salt has an expiration date from the secant that keeps it as a powder, but the one in the picture doesn't have it either.
Many places in the world mandate expiration dates on food items, no matter what the item in question actually is.
Water in a glass bottle? Expires in 24 months.
A lot of these laws have to do with expected lifetime in "worst plausible storage conditions", like poorly sealed boxes and wrong temperature and humidity
Yup, each batch needs to be stored in controlled conditions for the entire length of the expiration period. Many times the product expiration period is much longer, but controlled storage isn't cheap, so just companies just do the minimum required by them.
Bet it has more to do with salt caking up and getting nasty appearing than anything else other than just a legal requirement. Also I think that’s a “best by” date not an expiration.
