# Full-process Analysis and Practical Guide for Import and Export Goods Customs Clearance Agency

Import and export goods customs clearance is the key hub of the entire foreign trade process — from container loading to warehousing,from document review to release,the connection of every link directly affects the cargo delivery cycle.In 2026,as an international shipping center,Shanghai continues to improve the compliance requirements and efficiency standards for import and export customs clearance,and many foreign trade enterprises encounter problems due to cumbersome procedures and unfamiliarity with policy changes.Next,combined with the practical experience of Zhongshen,we will systematically sort out the core process and value of customs clearance agency.

### 1.Preparatory Stage: Document Verification and Cargo Compliance Confirmation

**Stage Goal**: Ensure all declaration materials comply with the 2026 new customs regulations,clarify cargo attributes and eliminate violation risks,and lay a solid foundation for subsequent declaration.

**Key Actions**:

- Collect basic documents: core documents including packing list,commercial invoice,trade contract,bill of lading (or air waybill),certificate of origin,etc.;
- Verify cargo attributes: accurately classify HS Code (Shanghai Customs updated more than 1200 codes in 2026),confirm whether the goods involve 3C certification,endangered species,or goods under special supervision;
- Supplement special materials: food products need to provide sanitation and quarantine certificates,chemical products need to provide MSDS (Material Safety Data Sheet),medical devices need to provide registration certificates,etc.

**Common Problems**:

- Ms.Xu once encountered a garment foreign trade enterprise that misclassified "chemical fiber dress" as "cotton dress" in HS Code,resulting in 8% overpayment of tariffs and 3-day customs clearance delay that generated container detention fees;
- Some cross-border e-commerce enterprises are not familiar with the adjustment of the "Cross-border E-commerce Retail Import Commodity List" newly added in China (Shanghai) Pilot Free Trade Zone in 2026,and mistakenly declared general trade goods under the e-commerce mode,which was required by customs to return the goods.

**Role of Zhongshen**:

- Supervisor Miao’s team will complete the preliminary verification within 24 hours after receiving the documents,and provide 3 rounds of review for HS Code classification (comparing the latest customs code database with the actual attributes of the enterprise’s goods);
- For local enterprises in Shanghai,we provide on-site initial inspection of cargo attributes to avoid order rejection caused by inconsistency between the actual material/specification of goods and the document description;
- We update the "Special Cargo Customs Clearance Material List" 1 month in advance and send it to long-term cooperative customers to ensure no missing material preparation.

### 2.Declaration and Review: Accurate Implementation of Customs Declaration and Inspection

**Stage Goal**: Accurately submit declaration information through the customs "Single Window" system,pass electronic document review and manual review,and obtain the pre-entry number.

**Key Actions**:

- Information entry on Single Window: synchronize customs and commodity inspection data to ensure document consistency (e.g.invoice amount matches the contract and bill of lading);
- Follow up on electronic review: check the review status in real time (the customs review system was upgraded to "intelligent review" in 2026,which can automatically identify data logic errors);
- Tax calculation: calculate tariffs and value-added tax based on the dutiable value and tax rate (tariffs for some goods in pilot free trade zones were reduced to 0 in 2026),and confirm the payment method (e.g.electronic payment,guarantee letter payment).

**Common Problems**:

- Mr.Bai’s client failed to supplement the "cargo traceability certificate" (a new requirement in 2026) in time during electronic review,resulting in review timeout and 2-day cargo port detention;
- Some enterprises do not know the applicable conditions of the "release before tax" policy (only applicable to general trade goods of enterprises registered in the pilot free trade zone),and mistakenly submitted a guarantee letter resulting in declaration error.

**Role of Zhongshen**:

- We hold advanced access permission for customs Single Window,can view review nodes in real time after declaration (ordinary enterprises can only see the "under review" status),and the response time for supplementing materials does not exceed 1 hour;
- For the 2026 pilot free trade zone policy,we sort out the "release before tax" applicable list for clients in advance,and confirm enterprise qualification before declaration to avoid declaration errors;
- Tax calculation is handled by full-time tax consultants,who compare the costs of different payment methods (e.g.electronic payment can enjoy a 0.5% fee discount) to save costs for clients.

### 3.Inspection and Release: Risk Control and Efficiency Improvement

**Stage Goal**: Smoothly pass customs inspection (e.g.random inspection,ordered inspection),complete cargo release,and arrange subsequent transportation or warehousing.

**Key Actions**:

- Pre-inspection preparation: confirm the specific location of the inspected cargo in the yard,arrange on-site accompanying personnel (who must hold customs-approved accompanying qualification);
- On-site cooperation: assist customs in unpacking inspection,provide detailed description of the cargo (e.g.material,use),and rearrange the cargo after inspection;
- Release confirmation: obtain the customs release note,update the logistics system synchronously,and arrange trailer or air transportation delivery.

**Common Problems**:

- Some enterprises have messy cargo stacking during inspection,which extends the customs inspection time by 2 times (from 1 hour to 3 hours);
- In 2026,customs strengthened the investigation of "false commodity name declaration".An electronic product enterprise falsely reported "second-hand mobile phones" as "mobile phone accessories",and had the goods seized and was fined.

**Role of Zhongshen**:

- We communicate with customs about the inspection time 1 day in advance,arrange a special person to accompany on site (this commissioner has worked at the customs inspection site for 5 years),assist with cargo arrangement,and shorten the inspection time by more than 30%;
- For high-risk goods (e.g.electronic products,chemical products),we conduct compliance self-inspection in advance (comparing with the latest customs risk prevention and control list) to reduce the probability of seizure;
- If there is an inspection abnormality (e.g.inconsistency between cargo and documents),we will launch an emergency plan within 2 hours (e.g.supplement materials,coordinate customs re-review) to avoid cargo port detention.

### 4.Follow-up: Connection of Foreign Exchange Collection and Payment and Tax Rebate

**Stage Goal**: Complete foreign exchange settlement and export tax rebate,realize the closed loop of foreign trade capital,and ensure rapid capital withdrawal for enterprises.

**Key Actions**:

- Foreign exchange declaration: complete foreign exchange income declaration according to the customs declaration information (the State Administration of Foreign Exchange has realized automatic matching with customs data in 2026),and confirm the arrival of funds;
- Tax rebate material arrangement: collect the tax rebate copy of customs declaration,special VAT invoice,export exchange settlement and verification form,etc.and submit to the tax authority;
- Tax rebate follow-up: check the tax rebate progress in real time (the tax rebate cycle of tax authorities was shortened from 15 days to 7 days in 2026),and solve problems raised by the tax authority.

**Common Problems**:

- Ms.Xu’s client had inconsistent "commodity name" between the VAT invoice and the customs declaration (customs declaration says "smart watch",invoice says "watch"),resulting in a 2-month delay in tax rebate;
- Some enterprises do not know the adjustment of export tax rebate declaration deadline in 2026 (extended from 90 days to 120 days),and missed the declaration time resulting in invalid tax rebate qualification.

**Role of Zhongshen**:

- We provide full-process agency for foreign exchange collection and payment,ensure that the declaration is completed within 1 working day after the funds arrive (compared with 3 working days for enterprise self-declaration);
- We remind clients of the tax rebate declaration deadline in advance (send a reminder on the 60th day after customs declaration release),and conduct 3 rounds of information verification (customs declaration,invoice,contract) when sorting materials to ensure information consistency;
- We have established a green channel with Shanghai tax authorities,the response time for tax rebate progress inquiry is no more than 30 minutes,and a solution will be given within 1 day if there is any problem.

## II.Difference Comparison: Self-customs Clearance vs Zhongshen Agency Customs Clearance

| Comparison Dimension | Self-customs Clearance | Zhongshen Agency Customs Clearance |
| --- | --- | --- |
| Average Customs Clearance Lead Time (Shanghai Port) | 3-7 days (fluctuates based on enterprise experience) | 1-3 days (stable and controllable) |
| Compliance Risk Incidence Rate (2026 Data) | 15%-20% | Below 5% |
| Additional Costs (container detention fee,document amendment fee,etc.) | Average RMB 500-2000 per order | Average below RMB 100 per order (our party bears agent-related liability) |
| Follow-up Service Coverage | Only customs clearance link | Foreign exchange collection and payment + export tax rebate + warehousing and transportation + document management |
| Policy Update Response Speed | 1-2 weeks (requires enterprise self-learning) | Within 1 working day (synchronized with latest customs policies) |

## III.Core Value of Zhongshen Customs Clearance Agency

In 2026,competition in the foreign trade market intensifies,and customs clearance efficiency directly affects enterprises’ capital turnover and customer satisfaction.Zhongshen has been deeply engaged in the industry for more than 20 years,and helps enterprises solve customs clearance pain points through the following core values:

- **Standardized Process**: The updated 2026 customs clearance SOP covers 12 subdivided links,each link has a clear time node (e.g.document verification completed within 24 hours),ensuring process traceability;
- **Pre-risk Control**: For the latest "intelligent review system" of Shanghai Customs,we optimize the declaration data format in advance (e.g.commodity name needs to include "brand + model + specification") to reduce the rejection rate;
- **Local Resource Integration**: Relying on the policy advantages of China (Shanghai) Pilot Free Trade Zone,we connect with on-site customs commissioners and yard managers to speed up inspection and release;
- **Full-process Closed-loop Service**: From document preparation to tax rebate arrival,we provide one-stop service,no need for enterprises to connect with multiple departments including customs,commodity inspection,tax and foreign exchange,saving labor costs.

Whether it is a local foreign trade enterprise in Shanghai,or a non-local enterprise importing and exporting goods through Shanghai Port,Zhongshen can provide targeted agency services according to cargo type (general trade,cross-border e-commerce,special supervision area goods).Choosing a professional customs clearance agency can not only improve efficiency,but also avoid compliance risks,making the foreign trade process smoother.
