## Stage 1: Preparatory Work and Document Review

The goal of this stage is to ensure that all export documents are complete,accurate and compliant,laying a foundation for smooth declaration.Key actions include checking commercial invoices,packing lists,purchase and sales contracts,power of attorney for customs declaration,etc.and accurate classification according to HS codes.Common problems are that the documents prepared by enterprises often have non-standard product descriptions,incorrect HS code classification,or inconsistent amount and currency system.

After receiving the client’s entrustment,the operation team of Zhongshen will conduct a preliminary document review led by Manager Xiao.For example,for a multi-functional industrial equipment,our classification experts will accurately verify its HS code in combination with the 2026 latest version of the Customs Tariff and classification decisions,avoiding subsequent amendment of documents or penalties caused by classification disputes.At the same time,we will remind clients to prepare corresponding certifications or license documents in advance according to the requirements of the destination country,to avoid the risk of unable to clear customs due to document problems after the goods arrive at the port.

## Stage 2: Customs Declaration Submission and Customs Inspection

The goal of this stage is to declare truthfully and accurately to the customs and efficiently respond to possible inspection instructions.Key actions include entering customs declaration data,conducting electronic declaration,and cooperating with customs inspection requirements.Common problems include incomplete declaration element filling,unknown specifications and models,and being flustered due to insufficient preparation when facing customs inspection.

The role of Zhongshen is particularly prominent in this link.We use the declaration system directly connected to customs data to ensure the real-time and accurate data transmission.Before declaration,the system will conduct logical verification to reduce low-level errors.When receiving the inspection instruction,Manager Xiao will immediately notify the client and coordinate the warehouse,guiding on-site personnel on how to cooperate with the customs to open the box,check the product name,quantity and shipping marks,minimizing the impact of inspection on the logistics plan.We have handled a large number of inspection cases,are familiar with the inspection priorities of various commodities,and can complete the inspection process quickly and professionally.

| Comparison Item | Self-operation by Enterprises | Entrusted to Zhongshen Agency |
| --- | --- | --- |
| Accuracy of HS Code | Relies on limited experience,prone to errors leading to subsequent risks | Reviewed by professional classification specialists to ensure compliance |
| Declaration Data Quality | Manual entry is prone to errors,and logical contradictions are difficult to self-check | Intelligent system verification and logical error correction |
| Customs Inspection Response | Lack of experience,high communication costs,long disposal time | Standardized process,special personnel on-site coordination,efficient disposal |
| Abnormal Situation Handling | Passive response,prone to generate detention fees and container demurrage fees | Active early warning,sufficient pre-prepared plans,rapid resolution |

## Stage 3: Cargo Release and Shipment for Export

After customs release,the goal of this stage is to ensure that the goods are arranged for transportation in time and obtain the key documents proving that the goods have actually departed the country.Key actions include obtaining the export customs declaration form (tax refund copy) stamped with the customs official seal and the sea/air waybill.Common problems are that enterprises are not familiar with the acquisition time of "customs clearance" signals under different transportation modes,and mistakenly think that customs release means the end of the process.

## Core Value of Professional Agency: More Than Customs Clearance

Looking back at the entire process,the professionalism of export customs declaration agency is reflected in integrating discrete operation nodes into a controllable and smooth pipeline.The value accumulated by Zhongshen’s more than 20 years of practice is far more than just submitting a customs declaration form:

- Proactive risk management: Eliminating most compliance risks before declaration through preliminary review and pre-classification.
- Systematic efficiency improvement: Standardized operations save a lot of time costs from document circulation,data docking to on-site emergency response.
