I am presently in search of Pseudo-Square Single Crystalline Silicon Wafers or Ingots for solar cell applications in very large quantity (200,000 pcs monthly). I am also in search of oil sand (4 million metric ton monthly), waste oil of all kinds (100,000 metric ton monthly) in very large amounts to be recycled for industrial uses. All of these are for long term, 3 years minimum. Therefore, I am hoping to establish a long term working relationship with the sellers. We usually make payment in the form of L/C. However, we are flexible if you have other preferred method of payment. Please kindly contact me by email or phone at your earliest convenient. I am looking forward to hearing from you soon. Trevor
