The integration of customs clearance has brought us great convenience. Through electronic declaration and electronic payment of taxes and fees, customs officers can complete the entire customs declaration process without leaving their homes, and the clearance process of goods only takes 20 minutes. The goods carried by Dongsheng Logistics Company now do not require customs transfer procedures and can be directly imported and exported at customs in Shenzhen and other ports. This not only saves logistics costs such as transportation by transit vehicles and entry into vehicle inspection yards, but also allows for immediate arrangements for import and export according to production and sales needs, without waiting for local customs to complete customs clearance procedures, greatly improving customs clearance efficiency and making logistics transportation between China and Hong Kong faster.
