In-fact this is one of our most significant industry advantages. We have been sourcing raw materials in china & qualifying both suppliers & products, for more than 15 year's time. Our raw material sourcing database now holds records on more than 15,000 different molecules, & more than 5,000 different chinese suppliers. As part of our daily sourcing activities, our Nanjing team is required to "qualify suppliers", & place all related information into the database for future reference. All materials are tested, vendor performance monitored, & results assessed & placed into the database. The result of all these efforts gives us an ability to find local raw materials very quickly, while preventing wasted time in working with unreliable high risk suppliers. This has proven to greatly reduce our R&D & production leadtimes, while giving our teams a greater range of materials & suppliers to choose from. On special request from our close customer-partners, we also perform a customized sourcing & supplier selection service to fit their individual needs for purchasing china materials. This includes material lot to lot analysis work, packaging service, factory visits/pre-audits, & full export management including customs clearance & door to door delivery.
