Labelling requirements for salt
Common name - salt and salt substitutes

Salt that does not contain 0.01% potassium iodide

The addition of iodide to salt for table or general household use is required to help in the prevention of goiter [B.17.003, FDR]. If a salt product does not comply with B.17.003, such as a natural mineral rock salt that is 98.32% sodium chloride and does not contain 0.01% potassium iodide, it cannot be sold to consumers for general household or table use. A common name that indicates the use, such as "salt for pickling" would be acceptable. Alternatively, the product may be sold for further processing and called "salt".

Sea salt and sea salts

The common name "sea salt" may be used to refer to processed salt from an existing sea and, when represented as sea salt for table or general household use, must meet the prescribed standard for salt. Salt from a mine cannot be labelled as "sea salt".

The common name "sea salts" (note the plural) refers to a mixture of sodium chloride and other mineral salts. Sea salts do not have to meet the standard for salt and as such, do not have to be iodized. Sea salts are made from sea water and not mining.
