This section provides information on the labelling requirements for salt (sodium chloride) and salt substitutes subject to the Food and Drugs Act (FDA), the Food and Drug Regulations (FDR), the Consumer Packaging and Labelling Act (CPLA) and Consumer Packaging and Labelling Regulations (CPLR). In addition, provincial regulations may also have labeling requirements for salt and salt substitutes that apply to products sold in that province.

The requirements detailed in the following sections are specific to salt and salt substitutes. They are in addition to the core labeling and claims and statements pages of the Industry Labelling Tool that apply to all prepackaged foods.

For the purpose of this information, salt other than crude rock salt, has a prescribed standard in Part B Division 17 of the FDR [B.17.001, FDR].Salt plays a functional role in many food categories. It is essential for maintaining product structure, enzymatic, humidity and microbial control, texture, emulsification, pH stability, flavour, food safety, stabilizing, preserving, etc.

Salt Substitutes do not have a prescribed standard and are generally a sodium reduced or sodium free alternative. Salt Substitutes usually contain potassium chloride. Table salt substitutes, while not required to, are permitted to contain added iodine [Part D Division 1, D.03.002 (1) Item 17, FDR].

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.

See Common Name for more information.

List of Ingredients - Salt and Salt Substitutes


All ingredients, including iodide, and their components must appear in the list of ingredients of table salt.

When used as an ingredient in the manufacture of a food product, the components of salt are not required to appear in the list of ingredients [B.01.009 (1), item 20, FDR].

Sea Salt(s)

When sea salt (note the singular "salt") is used as an ingredient, the same component exemption provided under B.01.009 (1), item 20, of the FDR for salt is applicable to sea salt.

The common name "sea salts" (note the plural "salts") is an acceptable common name for the ingredient list when referring to a mixture of sodium chloride and other mineral salts. A complete component listing is necessary, since it is not exempt under Section B.01.009 of the FDR.

Salt Substitutes

All ingredients and their components must appear in the list of ingredients of table salt substitutes. This includes the declaration of iodide if present.

When a salt substitute is used as an ingredient in another food, it must be declared by its common name in the list of ingredients. The term "salt substitute" on its own would not be acceptable. However it would be acceptable to declare the additive's function in brackets after the common name, for example, "potassium chloride (salt substitute)".

See List of Ingredients for more information.

Nutrition Labelling - Salt and Salt Substitutes

Salt for table or general household use containing added iodide that is declared on the principal display panel is not required to declare the iodide content in the Nutrition Facts table [B.01.402 (6)(g)]. In addition, the declaration of the iodide content on the principal display panel does not require the salt to contain a minimum 5% of the RDI for iodide [D.02.002(1), FDR].

See Nutrition Labelling for more information.

Product Specific Labelling Requirements

Iodide Declaration

Salt and sea salt sold for table or general household use are required to contain 0.01% Potassium Iodide and the presence of iodide is required to be shown on the principal display panel [B.17.003, FDR]. Salt and sea salt which has not been iodized is permitted as an ingredient of a food.

The presence of iodide in a salt substitute is not required to be shown on the principal display panel.

Voluntary Claims & Statements

Diet Specific Claims

A salt substitute that meets the compositional and labelling criteria for a free of sodium or salt claim or for a low in sodium or salt claim may be represented as a food for special dietary use, such as "For Salt Free Diets" or "For Salt Reduced Diets" [B.24.003 (1.1), FDR].

Refer to item h) in the Summary Table for Sodium (Salt) Claims for more information.

Nutrient Content Claims

A salt product represented as "Reduced in Sodium" is required to be formulated so that it contains at least 25% less sodium than regular table salt. Such a product must be labelled with the difference in the amount of sodium by percentage, fraction or milligrams per serving, for example, 50% Less Sodium than Table Salt, ½ the Sodium of Table Salt, 275 mg less Sodium per ¼ tsp.

Refer to Sodium (salt) claims for more information.
