What is express customs clearance?

Express customs declaration, also known as courier customs clearance or express customs clearance. It refers to the method of clearing goods through customs in the form of courier shipments, by submitting express waybills (such as KJ1, KJ2, KJ3 customs declaration forms) to customs on behalf of the courier company. 
　　
Why choose express customs declaration? What are its features? 
　　
1. Extremely simplified procedures. According to regulations such as the state's supervision and administration measures for inbound and outbound express shipments, in order to adapt to the customs declaration of express shipments that are "contracted, carried, and transported as fast commercial operation methods for inbound and outbound goods and items," a series of special arrangements aimed at simplifying procedures and speeding up the process have been made regarding supervision conditions and customs clearance (declaration and clearance) procedures. Therefore, under normal circumstances, consignors do not need to specially provide customs declaration forms, clearance documents, or licenses/approvals (for example, 3C compulsory certification, environmental certificates, import quotas, etc., are not required). 
　　
2. Extremely low costs. According to regulations such as the state's supervision and administration measures for inbound and outbound express shipments, express shipments can enjoy certain tax and fee reduction preferences when entering or leaving the country. Coupled with Shenzhen's geographical advantage of being close to Hong Kong, an international free port, convenient operations, low tax rates, and low operating costs naturally result in even lower costs. 
　　
3. Extremely fast speed. On one hand, due to the fewer mentioned supervision conditions and simplified procedures, time is naturally saved; on the other hand, the speed of clearance and inspection processes during transit embodies the "speed" of express shipments. Additionally, the customs supervision center for express shipments operates at night and works on Saturdays. 
　　
Under what circumstances are which types of goods most suitable for the import method of express customs declaration (courier customs clearance)? 
　　
1. Small-piece bulk cargo, small samples, and advertising items, etc.; 
　　
2. Various products lacking certain documents (for example, lacking 3C certification); 
　　
3. Urgent goods that cannot wait for the procedures of trade customs declaration and clearance in time; 
　　
4. Various products where costs need to be saved, and VAT invoices are not required; 
　　
5. Items for personal use. 
　　
Can large quantities or heavy goods also be imported through express customs declaration? Are there still advantages? 
　　
For bulk goods weighing tons or tens of tons, as mentioned above, it is completely possible to declare the entire shipment in batches or stages. Of course, this may have some slight impact on the overall shipment's speed; however, the two key advantages of extremely simplified procedures and extremely low costs remain. Thus, its advantages should still not be underestimated.
