According to Regulations on Edible Salt Iodization as a Means to Eliminate Iodine Deficiency Disorders, potassium iodate should be the main forticant. 3. Iodine content in edible salt 3.1 The average iodine content in edible salt (iodized salt) fortified with iodine fortificant (calculated by iodine) should be 20mg/kg to 30mg/kg. 3.2 The allowed fluctuation for the iodine content in edible salt should be ±30% of the average content stipulated in the section 3.1. 3.3 Health department of various provinces should choose the average iodine content appropriate to the local context based on the actual iodine nutrition of the local population according to Table 1 and from the range stipulated in section 3.1.
