How is sea salt handled and transported from its origin to the grocery store?

The answer to this question depends on the type of salt we're dealing with here. Rock salt, for example, is mined from large deposits in the earth. Sea salt, on the other hand, is obtained through evaporating sea water. When the water portion is boiled away, deposits of salt remain.

After the salt itself is produced, it is packaged in containers with little moisture (the presence of moisture causes the salt to partially dissolve and then stick to itself, causing the entire product to form compact and form one massive (or several large) salt crystal.) and shipped to individual distributors just like any other product. This means (if it was imported) that it was put into a shipping container, sent on either a boat or plane, and, upon its arrival, placed aboard a train and distributed to a series of semi-trucks that take the shipping container to the store in question.
