Dear Sir, Thanks for your email. Our company is also dealing in all kind of Chemicals and of course we can start a long term business relationship with you. We have been importing Carbon Black,Titanium Dioxide,Zinc Oxide,Rubber Accelerator,Formic Acid,Hydrogen Peroxide,Caustic Soda,DCP and many other chemicals. However we work under the following terms and conditions : 1) We require all prices based on CNF Karachi basis. 2) Our payment terms are T/T Transfer 90 days terms.So in such case all our suppliers usually contact thier export credit insurance companies and apply for a credit cover on our company.Once the credit is approved you can easily work on OPEN TERMS. I think in China you can contact SINOSURE which is one of the leading Chinese credit insurance company. If you accept our terms and conditions,then let us inform and we will give you our final orders. Awaiting your reply, Regards Arshad Sheikh 大伙有询盘都发出来吧 你做不成也许别人能做呢 互相帮助
