# 2026 Full Step-by-Step Detailed Analysis of Import Customs Declaration Agency Application Process

Import customs declaration agency service is a core link in the foreign trade import chain,which directly determines whether goods can be cleared on time and whether enterprises will incur additional costs.In 2026,as a national foreign trade hub,Shanghai’s import cargo volume increased by 12% year-on-year,but the customs’ requirements for commodity codes and declaration elements have continued to be refined.Many enterprises have problems such as return orders and inspection delays due to unfamiliarity with the process.Based on Zhongshen’s 20 years of practical experience,this article systematically sorts out the core process of import customs declaration agency application,helping enterprises clarify key actions at each stage.

## 1.Pre-declaration Preparation Stage: Compliance of Documents as the Foundation

The core goal of this stage is to ensure that all declaration documents are complete and the information is accurate,so as to avoid being returned by customs due to document issues.In 2026,the customs has stricter qualification audits for imported food and electronic products.Many enterprises delay customs clearance due to omitting the record for non-special purpose cosmetics or the exemption certificate for 3C certification.

### 1.Key Actions and Common Issues

- **Confirm Commodity Qualifications**: Handle qualification documents required by customs in advance according to the type of goods (such as cosmetics,new energy vehicle parts).Common problem: A trading company imported cosmetics without filing in advance,and the declaration was returned,delaying for 10 days.
- **Collect Core Documents**: Sort out basic documents such as commercial invoice,packing list,bill of lading,as well as supplementary documents such as commodity qualifications and certificate of origin.Common problem: The goods description on the bill of lading is inconsistent with that on the contract,leading to customs questioning the authenticity of the transaction.
- **Pre-classify Commodity Codes**: The customs updated 1,200 commodity codes in 2026.Incorrect classification may lead to overpayment or underpayment of tariffs.Common problem: An enterprise classified new energy vehicle batteries as ordinary batteries,with a tariff rate difference of 8%.

### 2.Zhongshen’s Exclusive Services

After connecting with client Ms.Luo,Manager Cao from Zhongshen will issue a exclusive document list based on the type of goods.For example,imported food needs to provide health certificate,certificate of origin,and record certificate for non-special purpose cosmetics; electronic products need 3C certification or exemption certificate for 3C.In response to the 2026 code update for new energy vehicle parts,Manager Cao arranged for dedicated personnel to update the code database in advance,helping Ms.Luo’s company avoid classification errors.In addition,Manager Cao will also assist Ms.Luo in checking the consistency of all documents,such as whether the number of goods on the bill of lading matches that on the packing list,to ensure no omissions before declaration.

## 2.Customs Declaration Form Submission and Customs Audit: Accurate Declaration as the Key

The goal of this stage is to complete the electronic declaration of the customs declaration form and pass the preliminary customs audit.In 2026,the customs has launched the "Smart Declaration Audit System",which has higher requirements for the accuracy of declaration elements.If the information is incomplete or incorrect,it will directly trigger manual audit and extend the customs clearance time.

### 1.Key Actions and Common Issues

- **Enter Declaration Information**: Accurately fill in declaration elements such as commodity name,code,quantity,unit price,and origin.Common problem: An enterprise omitted the "component content" element when declaring clothing,and was required to supplement by customs,delaying for 3 days.
- **Submit Electronic Declaration**: Submit the customs declaration form through the China International Trade Single Window,and ensure that the information is consistent with the paper documents.Common problem: The unit price in the electronic declaration is inconsistent with that on the invoice,leading to customs questioning the authenticity of the price.
- **Follow Up Audit Feedback**: Customs audit usually takes 1-2 working days.If there are questions,supplementary materials need to be provided in time.Common problem: An enterprise failed to check the audit feedback in time,resulting in declaration timeout and need to resubmit.

### 2.Efficiency Improvement of Zhongshen

Ms.Xie from Zhongshen is responsible for entering the customs declaration form.She is familiar with the 2026 new declaration elements required by customs (such as CAS number for some chemical products and UN number for dangerous goods),and will check the information consistency of the bill of lading,invoice and packing list one by one.After entering the information and submitting the declaration,if the customs raises questions (such as the fuzzy health certificate number of a batch of food),Ms.Xie will contact Ms.Luo to supplement the clear scan document in the first place,usually completing the feedback within 2 hours,which is 30% faster than the enterprise’s self-declaration.In addition,Ms.Xie will monitor the audit status in real time to avoid declaration timeout due to missing feedback.

## 3.Customs Inspection and Tax Payment: Compliance Response as the Core

The goal of this stage is to pass the customs inspection (if selected) and pay taxes in time to complete the release.In 2026,the customs inspection rate increased by 5% year-on-year,and the sampling inspection for imported food and cosmetics is stricter.If the goods do not match the declaration,they may be detained.

### 1.Key Actions and Common Issues

- **Cooperate with Customs Inspection**: If selected for inspection,prepare auxiliary materials such as goods samples and instructions.Common problem: An enterprise was found to have inconsistent goods marks with the declaration during inspection,and was detained for 3 days.
- **Calculate and Pay Taxes**: Accurately calculate tariffs,value-added tax and consumption tax,and pay in time to avoid late declaration fees.Common problem: An enterprise overpaid 20,000 yuan in taxes due to incorrect tariff rate application.

### 2.Comparison between Zhongshen Agency and Self-declaration

| Comparison Dimension | Enterprise Self-declaration | Zhongshen Agency Service |
| --- | --- | --- |
| Inspection Preparation | Need to contact the warehouse for stock preparation on your own,and may omit auxiliary materials required by customs | Manager Cao will sort out the inspection list in advance,arrange dedicated personnel to accompany the inspection,and prepare goods samples,instructions and other materials |
| Tax Calculation | Dependent on manual calculation,easy to make mistakes due to tax rate updates | Use tax calculation software connected to the customs system,which automatically updates tax rates after the 2026 tariff adjustment,with 100% accuracy |
| Payment Timeliness | Need to manually submit the payment application,and may incur late declaration fees due to process delays | Support real-time payment through the E-port,confirm the payment arrival within 1 hour after payment,and avoid late declaration fees |
| Inspection Problem Handling | Need to communicate with customs on your own,and may delay due to unfamiliarity with policies | Ms.Xie is familiar with customs inspection specifications.If goods mark problems are found,she can assist with on-site correction to reduce inspection time |

## 4.Goods Release and Follow-up: Logistics Coordination as the Guarantee

The goal of this stage is to release the goods smoothly and complete domestic transportation and verification procedures.In 2026,the storage fee in Shanghai ports increased by 10% year-on-year,and additional costs will be incurred if transportation is not arranged in time after release.

### 1.Key Actions and Common Issues

- **Confirm Release Information**: Check the release status through the Single Window to ensure that the goods can be picked up.Common problem: An enterprise failed to confirm the release in time,resulting in 2 days of cargo detention at the port and incurring demurrage fees.
- **Arrange Domestic Transportation**: Contact logistics providers to transport goods from the port to the destination.Common problem: An enterprise failed to arrange transportation in advance,resulting in delayed delivery of goods to customers.
- **Handle Verification Procedures**: Sort out documents such as customs declaration forms and tariff documents to handle foreign exchange verification.Common problem: An enterprise has incomplete verification materials,resulting in delayed arrival of foreign exchange.

### 2.Zhongshen’s Full Process Coordination

Mr.Chai (logistics liaison) from Zhongshen will contact Ms.Luo to confirm transportation needs within 1 hour after release,arrange a local warehouse in Shanghai or direct delivery,to avoid demurrage fees at the port.During the verification stage,Ms.Xie will sort out documents such as customs declaration forms,tariff documents and value-added tax documents,and assist Ms.Luo in handling foreign exchange verification,ensuring that funds arrive within 3 working days.The trading company where Ms.Luo works previously declared on its own,with an average customs clearance time of 7 days.After choosing Zhongshen,the time was shortened to 4 days,saving approximately RMB 2,000 per month in storage fees and demurrage fees.

## Summary: Professional Agency Makes Import Customs Declaration More Efficient
