Through the unremitting efforts of our colleagues in the Bulk Gas Division, our company has obtained the Class D driving license (hereinafter referred to as the "D license") for the cross-border transportation of dangerous goods between China and Vietnam. This achievement marks that our company can directly deliver argon and other products to customers with factories in Vietnam through land transportation. Land transportation has the characteristics of flexibility, convenience and short replenishment period, which makes up for the shortage of long maritime transportation period and high volume base. Greatly improve the supply guarantee of our customers in Vietnam.

D certificate has always been difficult to handle, high audit requirements, and more strict customs clearance detection. Relevant colleagues have invested a lot of energy and time to improve the qualification provision, license handling, stable supply of goods, transport vehicles and other links. Open up the main road transportation artery of our company from China to Vietnam, and upgrade the service for customers in Vietnam.
