II.Cargo Arrival & Declaration Stage: Efficient Operation to Shorten Clearance Cycle

Role of Zhongshen:

• Dedicated staff in charge of Single Window declaration.In 2026,the average declaration time at Chengdu Customs is shortened to 4 hours,and the declaration rejection rate of Zhongshen is only 3% (industry average is 12%)
• Established green channels with major shipping companies in Chengdu (such as Maersk,COSCO Shipping),compressed bill exchange time from 1 day to 4 hours
• Real-time monitoring of declaration status,notifies enterprises to supplement materials within 1 hour after rejection,avoiding secondary delays

• Handle import foreign exchange payment and subsequent verification (e.g.verification by the State Administration of Foreign Exchange)

Common Problems: Delay caused by warehouse queuing during pickup,insufficient foreign exchange quota for payment,chaotic subsequent warehousing management

Role of Zhongshen:

• Established priority pickup channels with local Chengdu warehouses (such as Chengdu International Logistics Park Warehouse),compressed pickup time from 2 hours to 30 minutes
• Assist enterprises with import foreign exchange payment,liaise with banks to provide support for foreign exchange quota application,avoid payment delay caused by insufficient quota
• Provide subsequent warehousing management services if required.In 2026,Zhongshen’s bonded warehouse area in Chengdu reaches 5000㎡,which can meet temporary warehousing needs

Enterprise Self-customs Clearance vs Zhongshen Agency Clearance: Core Difference Comparison

Common Misconceptions Reminder for Chengdu Import Customs Clearance

• Misconception 1: HS code can be filled casually.Wrong coding actually leads to 5%-20% overpayment of tariffs,and even penalty by customs (a Chengdu trading company once overpaid 120000 RMB in tariffs due to wrong coding)
• Misconception 2: Used imported equipment does not require prior procedures.In 2026,Chengdu Customs requires that used equipment must provide pre-shipment inspection certificate,otherwise it cannot be declared
• Misconception 3: No follow-up is needed after customs clearance is completed.In fact,some commodities (such as food,agricultural products) require subsequent quarantine sampling,Zhongshen will follow up the whole process until cargo delivery
