Well, I understand that with some years in an plastic bowl, the salt may absorb some substances and microplastics. But about Honey, what comes in glass jars? There they also put an expiration date, even though still edible honey has been found in several thousand years old Egyptian tombs.
The expiration date - unless it’s a different legal definition where you are from - is not really about being edible, but just signifies the guarantee the producer gives, basically “up until this date we will guarantee this product will maintain the expected quality”. In this case, I think it will be them not guaranteeing that the salt won’t have drawn water from the air and clumped up or something like that.
As a plastics engineer, I would be more concerned with the heavy metals in Himalayan pink salt. Also, any microplastics wouldn’t be “absorbed”.
If anything the salt would abraid the container through shaking which could scrape the walls and grind out some small particles over time. That being said, the plastics used for these types of applications are relatively virgin and frequently don’t contain any additives aside from possible colorants or glass fill or something line that.

It’s required by law so they have to put something.
