# Import Customs Clearance Agent Process and Core Notes

Mr.Fu,who runs an enterprise importing mechanical parts in Shanghai,recently encountered a problem: a batch of equipment imported from Germany was detained by customs for 3 days because the "certificate of origin" was missing in the customs declaration documents.This not only incurred storage fees but also delayed the production line commissioning.Such problems are not uncommon in the entire import customs clearance process—after all,from pre-arrival preparation to final release and pickup,every link hides compliance details and efficiency bottlenecks.Today,we will systematically sort out the core processes of import customs clearance and see what practical problems professional agents can help enterprises solve.

## 1.Pre-arrival Preparation Stage for Import Customs Clearance: No Panic with Complete Documents

The goal of this stage is to ensure that all customs declaration documents meet customs requirements and avoid being rejected due to incomplete documents in the follow-up.Key actions include document collection,qualification verification,and tariff estimation.

### 1.Basic Document List

Customs declaration documents vary slightly for different commodities,but the core list must include:

- Import and export cargo declaration form (must accurately fill in commodity code,quantity,amount,etc.)
- Commercial invoice,packing list (must be consistent with bill of lading information)
- Certificate of origin (required for some commodities to enjoy tariff preferences)
- Entry goods clearance form (required for commodities subject to statutory inspection to be handled in advance)
- Customs declaration power of attorney (required when entrusting an agency company)

Common problems: The "missing certificate of origin" that Mr.Fu encountered earlier was essentially due to failing to verify whether the commodity falls within the preferential tariff scope updated by the customs in 2026.In addition,some enterprises write inconsistent weights on the packing list and the bill of lading,which leads the customs to question the authenticity of the goods.

Role of Zhongshen: Remind enterprises to prepare documents 1-2 weeks in advance,and arrange dedicated personnel to verify commodity codes (the 2026 customs tariff schedule has over 300 adjustments,and some mechanical parts codes have changed significantly) to avoid paying more tariffs due to code errors.For example,last year,Manager Mo,who imports food,had the commodity code adjusted from "0402" to "0401" after verification by Zhongshen,reducing the tariff rate from 15% to 10%,saving nearly 20,000 yuan per batch of goods.

## 2.Declaration Stage After Cargo Arrival: Accurate Declaration is the Core

The goal is to complete customs declaration within the specified time and avoid incurring delayed declaration fees (charged at 0.05% of the cargo value per day if not declared within 14 days).Key actions include manifest confirmation,electronic declaration,and customs document review.

Common problems: Many enterprises have their declarations rejected because the "commodity description is too vague" during electronic declaration,such as only writing "mechanical parts" without specific models,making it impossible for the customs to classify accurately.In addition,the customs launched the "smart document review" system in 2026,and some sensitive commodities need to supplement and upload detailed pictures of the goods.Many enterprises have delayed the process due to lack of advance preparation.

Role of Zhongshen: Has a dedicated declaration team connected to the customs system,which can quickly respond to document review requirements.For example,in March this year,a batch of chemical materials of Manager Bi was rejected due to "insufficient component description".Zhongshen contacted the cooperative laboratory to supplement the component test report on the same day,completed the secondary declaration within 24 hours,and avoided about 8,000 yuan in delayed declaration fees.

## 3.Inspection and Release Stage: Compliance Determines Customs Clearance Speed

The goal is to pass the customs inspection smoothly and obtain the delivery order.Key actions include confirming the inspection notice,cooperating with on-site inspection,paying taxes and fees,and releasing and picking up the goods.

Common problems: "Discrepancy between actual goods and declaration" is found during inspection.For example,declaring "brand new equipment" but actually "used equipment" will result in customs penalties and requirement for re-declaration.In addition,some ports launched the "smart inspection" system in 2026,requiring enterprises to cooperate in uploading 360° high-definition pictures of the goods.Many enterprises have seen an increase in manual inspection rate due to blurry pictures.

Role of Zhongshen: Predicts inspection risks in advance.For example,before importing used equipment,remind enterprises to complete the "old mechanical and electrical products record" and arrange dedicated personnel to cooperate with on-site inspection and prepare all auxiliary materials.Last year,a batch of used printing equipment of Mr.Rao was released after only 4 hours of inspection after completing the record in advance with Zhongshen’s help,which is 60% faster than the average time of peers.

## 4.Follow-up Stage: Avoid Unresolved Issues

The goal is to complete the verification and cancellation,tax and fee document sorting and other work after picking up the goods,to ensure that the subsequent finance and business of the enterprise are not affected.Key actions include exchanging bill of lading for delivery order,filing verification and cancellation documents,and archiving tax and fee vouchers.

Common problems: Failure to file the verification and cancellation documents in time leads to restricted subsequent import quotas; loss of tax and fee vouchers affects the enterprise’s financial accounting and deduction.

Role of Zhongshen: Establishes exclusive customer files,sorts all customs declaration documents and archives them electronically,and provides 3 years of free query service.For example,the enterprise of Mr.Ai imports more than 10 batches of goods every year.Zhongshen’s file system can quickly retrieve the customs declaration forms within 3 years,helping him save a lot of financial verification time.

## 5.Self-declaration vs Professional Agency: Core Difference Comparison

| Comparison Dimension | Enterprise Self-declaration | Zhongshen Agency Declaration |
| --- | --- | --- |
| Time Cost | Average 7-10 days (need to go to customs and commodity inspection by yourself) | Average 3-5 days (full online connection,dedicated personnel follow-up) |
| Compliance Risk | Due to delayed update of policies,the rejection rate is about 20% | Fast synchronization of policy updates,rejection rate lower than 5% |
| Cost Control | Need to bear delayed declaration fees and tariff miscalculation losses (average about 3,000 yuan per batch) | Dedicated personnel verify tariffs,avoid miscalculation losses,no additional delayed declaration fee risks |
| Follow-up Service | Only complete release,no document archiving and cancellation reminder | Provide 3-year document archiving,cancellation and tax refund reminder |
| Applicable Scenarios | Annual import volume 5 batches,single commodity | Annual import volume >5 batches,multiple commodity types or involving sensitive commodities |

From Mr.Fu’s missing documents to Manager Mo’s tariff savings,from Manager Bi’s rapid re-declaration to Mr.Rao’s accelerated inspection,every link of import customs clearance cannot be separated from professional experience.Zhongshen has been deeply engaged in the industry for over 20 years,not only familiar with the latest customs policies in 2026,but also able to provide customized solutions according to the commodity types of different enterprises.Instead of groping to deal with various bottlenecks in customs declaration by yourself,it is better to hand it over to a professional team—after all,ensuring smooth arrival of goods is the first step of the enterprise’s import business.
