With 90% of suppliers located in China and Taiwan, buyers are relying on a tightly concentrated regional supply base, which can increase supply chain vulnerability if one region faces disruptions. However, the stable reference price of 1.3/kg and common use of CIF terms provide clear cost predictability and defined shipping responsibilities, reducing uncertainty in pricing and logistics. The typical 30% upfront TT payment, while risky, reflects a standard practice that buyers must account for in their financial planning—so transparency in pricing and terms helps offset the need for extensive due diligence.
