ANSWER
According to the Joint Circular Guiding the Goods Label for Some Foods, Food Additives and Aids for Processing Packaged Foods (No. 34/2014/TTLT-BYT-BNNPTNT-BCT), recommendations on nutritional comparisons for vitamins and minerals must comply with the conditions as stated in table below. In case Vietnam is yet to update recommendations on nutritional comparisons, instructions from Codex can be followed. Besides, organizations and individuals are encouraged to declare nutritional information in labels according to Codex.
Nutritional comparisons permitted labeling

* The value of 15 µg is based on minimal sunlight exposure throughout the year. Competent national and/or regional authorities should determine an appropriate NRV-R that best accounts for population sunlight exposure and other relevant factors.
** Competent national and/or regional authorities should determine an appropriate NRV-R that best represents the dietary absorption from relevant diets.
