Our monthly consumption is DOP(60 tons) and DOA(20 tons). Also I would like to know the prices of stabilizers such as calcium stearate, stearic acid and lead tribasic sulfate. Our monthly intake is calcium stearate (3 tons), stearic acid (2 tons) and lead tribasic sulfate (5 tons). I would also like to immediately clarify the cost of transportation.
