There are different types of sn grades such as technical grade, reagent grade, food grade, lab grade. The guides about sn here say the type of grade doesn't matter as long as the purity of the sn is at least 95%. I'm asking this because I'm still not sure about it and I want to see others opinions about this. I got sn from DMC but my parents found out and it and they took it away, their sn is food grade, at least that's what they say on their website. I ordered another package of sn from a different company, from BO, they're from Germany but they sell sn from the polish source BM. I got one package of 1 kg of sn, they say it has at least 98% purity on their website but they don't mention the grade type
