DON'T buy any product from them. We bought 13 fcls of STPP 94% for Brazil and they sent to my customers mixer cheap quality STPP instead of quality material  and not paid agreed commission. Our customers made analysis in SGS all results are same its low percentage cheap quality. Our customer offered them to pay all related costs and deliver back the materials. They did not accept. Because their aim was to cheat overseas customers. We request to all chemical overseas customers please don't buy any single product from them. This is a friendly WARNING.
