It is so sorry that we gave you a wrong translated name "changzhou changmao biochemical ..." when I wanted to correct the wrong name "changzhou huanghui biotechnology..." mentioned in your tables about FDA registration on 30 Sep 2014 as I was travilling outside
and can not check with my files, further more caused you paid more charges to FDA. it is so sorry.
We promise that we will try our best to quote most favorable price when you order dl-tartaric acid next time.
