Table 2.

The regulations for the labels of salt substitute products and packaged foods with added salt substitutes.

Country		The regulation for labels
Salt substitute products
	Canada [46]	All ingredients and their components must appear in the list of ingredients of table salt substitutes. This includes the declaration of iodide if present.
	India [45]	A declaration on the label as “low sodium salt substitute” or “low sodium dietetic salt” A declaration on the label regarding the amount of cations, that is, sodium, potassium, calcium, magnesium, ammonium, and choline/100 g (m/m), in the salt substitute mixture
Packaged foods added salt substitutes
	United States [48]	Exercise enforcement discretion for the declaration of “potassium salt” in the place of “potassium chloride” in the ingredient statement of food labels when potassium chloride is used as an ingredient in the food. Potassium and sodium are listed on the nutrition fact label on packaged foods and beverages.
	Canada [46]	Salt substitute 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).” A salt substitute that meets the compositional and labeling 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.”
	China [49]	“低钠盐的产品标签中应标示钾的含量，并应清晰标示： ‘高温作业者、重体力劳动强度者、肾功能障碍者及服用降压药物的高血压患者等不适宜高钾摄入的人群应慎用。’” Translation: the product label of low-sodium salt should indicate the potassium content and should clearly indicate that “it should be used with caution by people who are not suitable for high potassium intake, such as those who work in high temperature, those who work with heavy physical strength, those who have kidney dysfunction and those who take antihypertensive drugs for hypertension.”
