# 2026 Export Customs Declaration Agent Process: A Must-Read Operation Guide for Newbies

## I.Pre-work Preparation Stage: Complete Documents Are the Foundation for Faster Customs Clearance

In 2026,Shanghai Customs has stricter audits on the authenticity and compliance of customs declaration documents.Insufficient preparation in the early stage will lead to declaration return in mild cases,and even affect the cargo shipping schedule in severe cases.Mr.Xu,director of Zhongshen’s customs declaration department,often says: "Complete documents mean smooth customs clearance".The core of this stage is to ensure that all documents meet the latest policy requirements.

### 1.Stage Objectives and Key Actions

**Stage Objectives**: Complete the collection and review of customs declaration documents in advance,avoid declaration delays caused by missing or incorrect documents,and save time for subsequent links.

**Key Actions**:

- Collect basic information of export goods: including commodity code (HS code),quantity,weight,value,and certificate of origin (if tariff preferences are applicable)
- Organize enterprise qualification documents: updated in 2026 to include "Customs Enterprise Credit Management Certificate","Registration Form for Foreign Trade Operators",and power of attorney for customs declaration (needs customer’s signature and seal)
- Confirm transportation and storage arrangements: contact Mr.Han,head of Zhongshen’s warehouse department,to verify whether the goods have been packed and labeled,and whether the bill of lading information is consistent with the packing list

**Common Problems**:

- Incorrect HS code classification: In 2026,Customs has adjusted the HS codes for emerging commodities such as smart wearable devices and new energy accessories,which are easily misjudged by clients
- Expired certificate of origin: Some countries require the certificate of origin to be valid within 3 months,and clients often fail to enjoy tariff preferences due to negligence
- Inconsistent information between bill of lading and packing list: For example,the bill of lading shows 100 cartons while the packing list shows 99,which will arouse Customs’ suspicion

**Zhongshen’s Support**:

- Mr.Xu’s team reviews all documents 1-2 days in advance,and checks the HS codes with the 2026 latest Customs code database to avoid classification errors
- Mr.Han reminds clients to prepare the certificate of origin synchronously when the goods enter the warehouse,and establishes a "document expiration reminder" mechanism
- The system automatically compares the core information of the bill of lading,packing list and invoice,and immediately feedbacks for adjustment if inconsistencies are found,to avoid declaration errors

## II.Customs Declaration Stage: Accurate Operation Is the Core of Smooth Customs Clearance

In 2026,Customs has fully implemented electronic declaration via the "Single Window",and paper documents only need to be retained for reference.However,inconsistent declaration data with actual goods will still trigger the AI risk assessment system,leading to delays in manual review.All customs declarers of Zhongshen hold the 2026 updated "Customs Declaration Professional Qualification Certificate",with a declaration accuracy rate of over 99%.

### 1.Stage Objectives and Key Actions

**Stage Objectives**: Accurately submit declaration data via the Customs Single Window,pass the review on the first attempt,and reduce the number of return orders.

**Key Actions**:

- Enter declaration data: Fill in information such as goods description,value,transportation method and destination in the Single Window system
- Upload electronic documents: PDF scans of invoices,packing lists,contracts and certificates of origin (must meet Customs format requirements)
- Pay tariffs and VAT: Calculate based on the commodity code and the tax rate of the destination country,and pay online via the Single Window if required

**Common Problems**:

- Declaration value deviates from market prices: In 2026,the Customs AI system will compare transaction data of similar commodities,and manual review will be triggered if the gap exceeds 10%
- Incorrect electronic document format: For example,the certificate of origin is not stamped with an electronic seal,resulting in upload failure
- Delayed tariff payment: Some clients fail to pay on time due to delayed arrival of foreign exchange,which affects cargo release

**Zhongshen’s Support**:

- Establish a value assessment model: Combine the 2026 transaction data of similar commodities at Shanghai Port to predict the rationality of the declaration value in advance
- Provide electronic document format verification service: Ensure that all uploaded documents meet Customs requirements and avoid format errors
- Provide tariff advance payment service for clients with credit rating of Grade B or above,to ensure timely payment and no impact on customs clearance efficiency

## III.Inspection and Release Stage: Efficient Cooperation Is the Key to Faster Customs Clearance

In 2026,the Customs inspection rate is about 15%,and the duration of inspection directly affects the cargo shipping schedule.Mr.Han,head of Zhongshen’s warehouse department,said: "Pre-inspection preparation can shorten the inspection time by half."

### 1.Stage Objectives and Key Actions

**Stage Objectives**: Pass Customs inspection smoothly (if selected),quickly obtain release instructions and arrange cargo loading.

**Key Actions**:

- Confirm inspection notice: Zhongshen’s system synchronizes the Customs inspection notice within 1 hour and informs the client of the inspection time and location
- Prepare goods for inspection: Mr.Han’s team transfers the goods to be inspected to the Customs-designated inspection area and arranges them in the order of declaration
- Cooperate on-site during inspection: Zhongshen’s declarers accompany the inspection,answer questions and provide supplementary documents

**Common Problems**:

- Misplaced goods: Mixed loading makes it difficult for inspectors to quickly find the target goods,prolonging the inspection time
- Inconsistent samples and declaration: Declared as "brand new smart watch" but actually "used",which arouse Customs’ suspicion
- Conflict with inspection time: Clients have tight shipping schedules and cannot cooperate with the inspection in time,resulting in cargo detention

**Zhongshen’s Support**:

- Mr.Han’s team sorts and arranges the goods in advance and marks clear commodity information to help inspectors locate quickly
- Recheck the samples and declaration information before inspection to ensure consistency and avoid inspection failure due to sample issues
- Mr.Xu has established an emergency coordination mechanism with the Customs Inspection Division,which can prioritize inspection or coordinate ship replacement when clients have tight shipping schedules

## IV.Follow-up Stage: Closed-loop Management Is the Guarantee for the Entire Foreign Trade Process

Release is not the end.Subsequent verification and export tax rebate directly affect the capital recovery of enterprises.In 2026,the average arrival time of export tax rebates is about 7-10 days,but incorrect documents will cause delays.Mr.Du from Zhongshen’s tax rebate department follows up the whole process to ensure smooth tax rebates.

### 1.Stage Objectives and Key Actions

**Stage Objectives**: Complete Customs verification,assist clients in handling export tax rebates and ensure timely capital recovery.

**Key Actions**:

- Obtain electronic release certificate: Send the certificate to the client within 1 day after release as the delivery voucher
- Handle foreign exchange verification: The foreign exchange team tracks the arrival of foreign exchange and completes verification in the SAFE system
- Assist with export tax rebates: Organize customs declarations,VAT invoices and foreign exchange verification forms and submit them to the tax authorities

**Common Problems**:

- Inconsistent information between customs declaration and invoice: Discrepancies in commodity names and quantities lead to tax rebate failure
- Delayed arrival of foreign exchange: Overseas buyers fail to pay on time,making it impossible to complete verification in time
- Missing tax rebate documents: Missing VAT invoice deduction coupons lead to return of applications by tax authorities

**Zhongshen’s Support**:

- Establish a joint review mechanism for customs declarations and tax rebate documents,and check information immediately after release to ensure consistency
- The foreign exchange team tracks the arrival of funds in real time and reminds clients to complete verification in time
- Mr.Du assists in supplementing missing documents,with a 98% first-pass rate for tax rebate applications,which is 3 days faster than the industry average
