I am in need of a commercial grade Hydrazinum Sulphate . We are an R&D company "Bilal Rubber, Lahore" and for initial testing we will be needing a sample of 20kg and the next supply chain will be established later. 
Please give us the most likely quote for this. Due to chemicals unavailability locally we will be reaching large scale suppliers and vendors and may the best quote wins.
