Please kindly let me introduce my company to you that we are one of largest manufactures in China who mainly produce chemical products, such as barium carbonate,thiourea?thiourea dioxide etc. Our annual output of barium carbonate is 20000 tons, and thiourea 3000tons. I know you need import chemical products from China. I'll be very appreciated if you can tell me the detail information about products you want. I'd like to start our business on the basis of equality, mutual benefit and exchange of needed goods.
