My name is Jackson Megiatto, I am PhD in Chemical Engineering. We are about to launch a large project to produce veterinarian products in Brazil and we are going to need a regular supply of Tylosin Base soon. We estimate a consumption of about 70-80 ton of Tylosin Base per month. So, we are looking for suppliers with big production capacities to provide us with such large amounts of Tylosin Base. If we would order from you about 70-80 ton of Tylosin Base per month (there is the possibility to make a supply contract, if possible on your side), what would it be the quotation of Tylosin Base. We also need please a quotation for Tylosin Phosphate (CAS # 1405-53-4). 
Thank you.
