### I.Preliminary Preparation: Customer Connection and Document Review (Goal: Ensure Documents Comply with 2026 New Customs Regulations)

This stage is the foundation of the customs declaration process.If there is any deviation in the documents,the subsequent declaration will be returned directly.Ms.Jiang,Document Supervisor of Zhongshen,will focus on confirming the following key actions during connection:

- Check basic cargo information: including HS code,origin,quantity,weight,packing method,etc.which must match the 2026 latest edition of Customs Import and Export Tariff
- Review basic documents: contract,commercial invoice,packing list,bill of lading copy (sea/air freight),product inspection and quarantine certificate,etc.
- Confirm special supervision requirements: documents newly added in 2026 such as food traceability code,electronic supervision filing for medical devices,environmental protection certification,etc.

Common Problems and Solutions from Zhongshen:

• Customer misreports HS code: Ms.Jiang will check the tax rate and supervision conditions corresponding to the code in advance through Zhongshen’s customs pre-classification system,avoiding extra tariff payment caused by wrong code;

• Lack of 2026 new regulation required documents: Zhongshen provides "2026 Customs Declaration Document Checklist Template",clearly marks newly added required documents,reduces customers’ time for repeated document supplement;

• Special cargo (such as lithium batteries): connect with the customs special commodity supervision department in advance,confirm the newly added transportation and packaging requirements in 2026,avoid the situation that cargo cannot be loaded after arriving at the port.

### II.Document Production and Electronic Declaration (Goal: Accurate Declaration,Improve Customs Clearance Efficiency)

Customs has realized full-process electronic declaration in 2026,and traditional paper documents are gradually phased out.Manager Zhang,Customs Declaration Supervisor of Zhongshen,will lead the following operations:

• Produce customs declaration form: fill in the customs declaration information on the Customs Single Window according to the reviewed documents,focus on checking fields such as "commodity name and specification","transaction method","freight/insurance premium";

• Intelligent verification: automatically match the customs database through Zhongshen’s upgraded document verification system,check information consistency (such as whether the invoice amount matches the contract,whether the HS code matches the commodity);

• Electronic declaration: connect to the direct channel of Customs Single Window,monitor system feedback in real time after submitting the declaration.

Common Problems and Solutions from Zhongshen:

• Inconsistent document information: Manager Zhang’s team conducts "double-person cross review" before declaration,and the return rate caused by information error has been only 1.2% since 2026;

• System lag: if the Customs Single Window is congested,Technical Support Manager Gan will assist to switch to the backup declaration channel,ensure the declaration is completed within 1 hour without affecting the cargo loading plan;

• Declaration returned: after receiving the return notice,Manager Zhang will analyze the cause within 30 minutes (such as lack of product certification),and assist customers to supplement documents and re-declare.

### III.Cargo Inspection and Port Release (Goal: Pass Inspection Smoothly,Ensure On-time Loading)

This stage is the core risk point of the customs declaration process.The customs inspection rate in 2026 is slightly higher than that in 2025 (about 8%),mainly targeting high-risk commodities (such as electronic products,food).Supervisor Meng,in charge of on-site coordination of Zhongshen,is responsible for the following operations:

• Book inspection: book off-peak inspection time in advance according to the arrival time of cargo at the port,reduce waiting time in queue;

• Accompany inspection: prepare reference materials such as cargo samples,labels,origin certificates,assist customs to check the consistency of cargo and declaration information;

• Process release: after passing the inspection,submit the release application on the Customs Single Window and obtain the "Electronic Release Note".

Common Problems and Solutions from Zhongshen:

• Inconsistency between cargo and documents: Supervisor Meng will check the specification and quantity of cargo again before inspection,and the cargo detention rate of cargoes agency by Zhongshen has been only 0.5% since 2026;

• Inspection dispute: if customs has questions about the cargo attribute,Supervisor Meng will contact the customs communication specialist of Zhongshen,provide product technical materials,test reports,etc.to coordinate and solve the problem quickly;

• Overlong inspection time: for urgent cargo (such as cross-border e-commerce orders),Supervisor Meng will apply for the "Green Channel",and the inspection time is 40% shorter than that of ordinary cargo.

### IV.Follow-up and Document Archiving (Goal: Complete Follow-up Procedures,Support Tax Refund and Other Links)

Although this stage seems to be the closing part,it directly affects enterprises’ export tax refund and subsequent business.Ms.Jiang,Document Supervisor of Zhongshen,is responsible for the following operations:

• Document archiving: organize full set of documents including customs declaration form,release note,inspection and quarantine certificate,scan and upload to the electronic file system,customers can check online at any time;

• Tax refund support: assist customers to process the "Customs Declaration Certificate Copy" (electronic printing has been realized in 2026),and provide tax refund policy consultation (for example,the tax refund rate of some new energy products has been increased to 16%);

• Transportation follow-up: feedback the status of cargo loading,departure and arrival,remind customers to handle customs clearance procedures in the importing country.

Common Problems and Solutions from Zhongshen:

• Incomplete document archiving: the electronic file system automatically generates the "Tax Refund Document Checklist",ensuring customers obtain all required documents;

• Extended tax refund cycle: Zhongshen synchronizes data with customs,the acquisition time of "Customs Declaration Certificate Copy" is 3 working days faster than the industry average,and the tax refund cycle is shortened to 10-12 working days;

• Subsequent disputes: if customers have problems with importers due to cargo customs clearance,Ms.Jiang will provide full set of customs declaration documents as vouchers to assist customers to handle disputes.
