The application of carbonyl iron powder Food Grade
Food grade carbonyl iron powder is mainly used in animal feed and nutritional iron supplement in European and American countries. The main index of the product is that the content of heavy metals meets the European Union standard. The heavy metals in our products only contain nickel. Through process adjustment, it has been in line with the European Union animal feed and nutritional iron supplement.
