1.Preparatory Preparation and Document Verification: Compliance Pre-position is the Foundation for Accelerating Customs Clearance

The core goal of this stage is to ensure all import documents comply with the latest 2026 customs regulatory requirements,avoiding application rejection due to missing or incorrect documents.

Key Actions：

• Verify cargo HS code: According to the latest 2026 tariff schedule,accurately determine the corresponding HS code of the cargo,clarify the tariff rate and type of regulatory documents;
• Verify basic documents: including import contract,commercial invoice,packing list,bill of lading (sea/air freight),certificate of origin,etc.;
• Apply for regulatory documents: such as import license,3C certification,animal and plant quarantine certificate,etc.(determined according to cargo category).

Common Problems：Incorrect HS code classification leads to overpayment of tariffs (the tariff difference for some cargo can reach 15%),delayed application upon arrival due to untimely regulatory document processing,and inability to enjoy preferential tariff rates because the certificate of origin does not meet requirements.

Role of Zhongshen：Ms.Feng,a foreign trade document specialist,is arranged to liaise with customers,review the document list 10 working days in advance,and accurately verify HS codes based on over 20 years of experience in tariff schedule updates.If regulatory documents are involved,we assist customers in preparing application materials and liaise with relevant authorities for processing.Since 2026,we have helped 300+ customers avoid extra costs caused by code errors.

2.Customs Declaration,Inspection and Clearance Operation: Precise Liaison with Customs to Improve Release Efficiency

The core goal of this stage is to successfully pass customs declaration and inspection,and achieve rapid release of cargo.

Key Actions：

• Electronic declaration through single window: Submit all documents via China International Trade "Single Window",synchronize with customs and inspection and quarantine authorities;
• Coordinate with customs inspection: If the cargo is randomly inspected,prepare samples,verify cargo information,and coordinate with on-site inspectors;
• Tax payment: Pay tariffs and value-added tax on time according to the tax bill issued by customs (part of the tax can be deducted for certain cargo).

Common Problems：Electronic declaration is rejected (mostly due to logical contradiction in documents),excessive inspection time (some enterprises wait over 5 working days),and overdue payment caused by incorrect tax calculation.

Role of Zhongshen：Manager Du,the customs declaration operation supervisor,is in charge of single window declaration.He is familiar with 2026 customs declaration rules,can check logical problems of documents in advance,and the declaration passing rate reaches 98%.If the cargo is inspected,we prepare the inspection list and samples in advance,liaise with customs inspectors,and the average inspection time is shortened to 2 working days.We also calculate taxes accurately and provide pre-tax calculation services to avoid late payment fines.

3.Domestic Transportation and Delivery: Full-link Tracking to Ensure Cargo Safety

The core goal of this stage is to deliver the cleared cargo safely and on time to the location designated by the customer.

Key Actions：

• Select transportation mode: Choose land transportation,sea transit or air transportation according to cargo type (such as fragile cargo,cold chain cargo);
• Warehousing transit: If temporary storage is required,arrange storage in Shanghai bonded warehouse or ordinary warehouse (intelligent warehousing system added in 2026);
• Last-mile delivery: Liaise with domestic logistics service providers,track cargo trajectory,and confirm receipt.

Common Problems：Cargo damage during transportation (especially temperature fluctuation for cold chain cargo),delivery delay (such as logistics congestion during holidays),and untimely receipt information.

Role of Zhongshen：Ms.Ge,a logistics coordination specialist,selects the optimal transportation plan according to cargo characteristics.For example,for cold chain cargo,we liaise with logistics providers with temperature and humidity monitoring,and customize cushioning packaging for fragile cargo.Relying on local warehousing resources in Shanghai,we provide 24-hour warehousing transit services.We share logistics trajectory in real time,and customers can inquire via exclusive portal.Since 2026,the on-time delivery rate of cargo reaches 99%.
