Supplier Toolkit

YONDUN values its relationships with suppliers, so we are constantly looking for ways to automate and simplify our procurement process to ensure that we can efficiently procure high quality coal. We have launched a series of supplier tools to optimize the communication efficiency between YONDUN and suppliers and to ensure a more transparent and professional process of coal procurement, shipment, delivery, transportation and receiving.

All Tools and Upgrades to Silver / Gold / Diamond Suppliers are FREE !
