DPE sources components from qualified and reliable vendors. Our vendor rating system assures that we receive only top quality parts. And all these suppliers will be continuously evaluated, classified and monitored.


Before qualified, a potential vendor has to submit a complete documentation including compresive background, so that DPE can have a understanding like trade ability, bank reference, financial information and other references.


When above qualification accepted by DPE, we will perform an on-site visit to supplier – to have a deep understanding of potential supplier’s managment system, business policy, ordering procedures and other business oppotunities.


To ensure the new vendors can meet our standards for service, delivery and quality, they must be finally approved by DPE management. And a purchasing agreement is required before the vendors can receive orders. Only with all above accepted, DPE can start business with the new vendors.


Based on years of knowledge surrounding quality assurance and counterfeit prevention, our primary inspection includes careful examination of parts from outer packaging inward.
