All ethanol imported are made from wheat, sugar cane, molasses, corn or other natural grains. We put efforts in ensuring the quality of our imported ethanol, so our customers can have the ethanol they want. Firstly, we ensure the quality is in line with the CNS regulation about edible ethanol.  Secondly, we use higher standards, such as BP, EP, USP Pharmacopoeia norms, as a test standard if our customers suggest.  Next, we imported ethanol mainly from the top ten advanced medical countries announced by the Ministry of Health and Welfare.  Lastly, we also provide a wide range of professional certificates and inspection documents for each batch, so our customers know what kind of ethanol is provided to them.  The establishment of raw materials tracking system could be done.
