We have very strong advantageous for Ferrous Sulphate, not only for FeSO4.H2O,but also for FeSO4.7H2O;not only for fine powder, but also for granular, big granular,middle granular, small granular; we can use 2 kinds of production methods to produce FESO4,one is "drying method", another : "wet method", both are able to reach "feed grade", Components: Guaranteed Analysis: Typical Analysis: Total Iron(Fe): 30%min 30.5% Heavy Metal(As Pb): 0.002% max 0.0005% Cadmium (Cd): 0.002% max 0.0004% Arsenic(As): 0.0005%max 0.0001% Components: Guaranteed Analysis: Typical Analysis: Total Iron(Fe): 19.7%min >20.1 % Heavy Metal(As Pb): 0.002% max <0.0015% WaterInsoluble Matter: 0.5% max <0.2% TiO2: 1% max 0.5% H2SO4: 1% max 0.51% Arsenic(As): 0.0005%max <0.0003% **Our FeSO4 powder have very good free-flowing, and very average size; **Because our raw material of FeSO4 is controlled strictly, our FeSO4 can meet and reach standard of European Union for Dioxins & PCBs; More detailed information or questions, please kindly contact us! ----------------------------------------------------------------------------------------------- -We Finished Pre-Registration As Per Reach With 19 Kinds Of Chemicals. -We Have Already Obtained Certificate of "Fami-Qs" Through Bv. -We Have Already Obtained Certificate of "ISO9001:2008" Through SGS -----------------------------------------------------------------------------------------------
