Self-handle Import and Export Agency? Core Processes and Key Pitfalls to Avoid

Sorting out the Process and Core Links of Self-handling Import and Export Agency

Self-handling import and export agency is a choice for many foreign trade enterprises to expand international business.However,this business covers multiple core links such as customs declaration and inspection,international transportation,and foreign exchange receipt and payment.Operational deviations in each link may affect the customs clearance efficiency of goods or lead to compliance risks.Since 2026,the number of delayed cases in Shanghai caused by problems such as incorrect customs declaration forms and incomplete tax refund documents when handling by themselves has increased by 12% year-on-year.Therefore,it is particularly important to systematically sort out the process and clarify the key actions of each stage.

I.Pre-qualification Preparation and Document Verification: Lay a Solid Foundation for the Process

The goal of this stage is to ensure that the enterprise has the basic qualifications required for import and export agency,with complete and accurate documents,so as to avoid subsequent process stagnation due to qualification issues.

1.1 Key Actions

• Confirm whether the enterprise has completed the registration of import and export business qualification (in 2026,Shanghai requires submitting electronic documents via the China International Trade Single Window,no on-site submission of paper documents is needed)
• Verify the HS code corresponding to the goods (must match the actual attributes of the goods; 12 categories of products such as new energy vehicle parts have added detailed codes in 2026)
• Prepare basic trade documents such as contracts,invoices,and packing lists (must be consistent with the actual goods; note that some EU countries in 2026 require electronic documents to be uploaded to their official systems)

1.2 Common Problems

• Some enterprises mistakenly believe that having a business license is sufficient for handling,and ignore the registration of import and export business qualification (in 2026,enterprises in Shanghai that have not completed registration cannot submit customs declaration applications via the Single Window)
• Incorrect HS code classification (e.g.misclassifying biodegradable plastic products as ordinary plastic products,leading to a 5% difference in tariff rates)
• Inconsistent document information (e.g.a 5% difference in the quantity of goods between the contract and the packing list,which leads to customs return of documents if not corrected in time)

Manager Luo from Zhongshen mentioned that the company can assist enterprises in verifying the status of import and export business qualification registration,provide classification suggestions for the newly added HS code adjustments in 2026,and establish a document verification checklist to ensure that the information of contracts,invoices,packing lists,etc.is fully matched,avoiding process delays caused by document issues.

II.Customs Declaration and Inspection: The Core Link to Ensure Smooth Customs Clearance of Goods

The goal of this stage is to complete goods declaration,customs review and release,and ensure that goods are shipped or imported on time.In 2026,the customs clearance efficiency of Shanghai Customs has been shortened by 10% compared with 2025,but delays still easily occur when handling by themselves.

2.1 Key Actions in Customs Declaration Process

• Submit the customs declaration form via the China International Trade Single Window (in 2026,it is required to fill in "commodity traceability information",such as filling in the origin traceability code and production batch number for agricultural products)
• Cooperate with customs inspection (if inspection methods include manual inspection and machine inspection,prepare instructions for the stacking location of goods and relevant documents in advance)
• Pay tariffs and value-added tax (in 2026,enterprises in the Shanghai Free Trade Zone can enjoy the tariff guarantee policy without paying a deposit in advance)

2.2 Common Problems in Customs Declaration

• Incomplete filling of "commodity traceability information" on the customs declaration form (e.g.some food enterprises fail to fill in the raw material origin traceability code,leading to a 30% increase in customs inspection rate)
• Disordered stacking of goods during inspection,leading to extended inspection time (in 2026,the average inspection time of Shanghai Customs is 24 hours,and disordered stacking may extend it to 48 hours)
• Incorrect tariff calculation (e.g.failing to consider the 2026 RCEP agreement tariff rate,some products can enjoy a 10% tariff reduction)

2.3 Precautions for Inspection and Quarantine

• Confirm whether the goods need to go through commodity inspection (e.g.cosmetics and medical devices need to provide health certificates; in 2026,the inspection process for some industrial products has been simplified to self-declaration)
• Submit the inspection and quarantine application via the Single Window (in 2026,it is required to upload electronic copies of product test reports,which must be valid within 6 months)
• Cooperate with on-site sampling by inspection and quarantine personnel (prepare more than 3 samples in advance,and the samples must be consistent with the actual goods)

2.4 Common Problems in Inspection and Quarantine

• Failing to handle commodity inspection in time leads to inability to declare customs (in 2026,15% of customs detention cases in Shanghai are caused by inspection delays)
• Expired test reports (e.g.some electronic product test reports expired for 1 month,leading to rejection of inspection application)
• Non-compliant samples during sampling (e.g.food samples not sealed properly,leading to invalid test results)

Supervisor Nie from Zhongshen stated that the company has more than 20 years of customs declaration experience,can assist enterprises in accurately filling in the newly added customs declaration fields in 2026,plan the stacking of goods in the inspection area in advance,and be familiar with the tariff application rules of free trade agreements such as RCEP,to reasonably calculate tariffs for enterprises and avoid overpayment or underpayment.For the inspection link,the company can assist enterprises in sorting out the 2026 inspection policy changes,review the validity period of test reports in advance,and arrange special personnel to cooperate during on-site sampling to ensure smooth passage of inspection.

III.International Transportation and Warehousing Coordination: Ensure Logistics Efficiency

The goal of this stage is to select the appropriate transportation method,coordinate the warehousing and transportation links,and ensure that goods are shipped on time.In 2026,the container throughput of the Port of Shanghai is expected to reach 47 million TEU,and transportation resources are tight,so advance planning is required.

3.1 Key Actions

• Compare the timeliness and cost of sea transportation,air transportation,and railway transportation (in 2026,there are 12 weekly trains on the Shanghai section of the China-Europe Railway Express,an increase of 2 trains compared with 2025)
• Confirm warehousing service needs (e.g.bonded warehousing,general warehousing,which must match the attributes of goods; in 2026,the bonded warehousing area in Shanghai has increased by 1 million square meters)
• Handle cargo transportation insurance (in 2026,some insurance companies have launched exclusive insurance products for cross-border e-commerce goods,covering the entire process of transportation and warehousing)

3.2 Common Problems

• Inappropriate selection of transportation method (e.g.choosing sea transportation for urgent orders leads to delays; in 2026,the sea transportation time from Shanghai to Europe is 35 days,and air transportation is 10 days)
• Poor coordination between warehousing and transportation (e.g.no buffer time reserved for the transportation time from warehouse to port,leading to missing the shipping schedule)
• Incomplete insurance coverage (e.g.not covering the damage risk of goods during warehousing; in 2026,8% of warehousing damage cases occur in Shanghai)

Mr.Gan from Zhongshen introduced that the company has long-term cooperation with multiple shipping companies and airlines,and can provide the optimal transportation plan according to the timeliness requirements of goods.For urgent orders,air freight space can be arranged preferentially.At the same time,the company integrates more than 10 warehousing resources in Shanghai to achieve seamless connection between warehousing and transportation.It can also assist enterprises in selecting appropriate transportation insurance to cover the entire process risks,reducing transportation costs by an average of 5%.

IV.Foreign Exchange Receipt and Payment,Exchange Settlement and Purchase: Avoid Exchange Rate Risks

The goal of this stage is to safely receive and pay foreign exchange,reasonably conduct exchange settlement and purchase,and avoid losses caused by exchange rate fluctuations.In the first half of 2026,the exchange rate fluctuation of USD to RMB reached 3%,so exchange rate risks need to be focused on.

4.1 Key Actions

• Handle the opening of foreign exchange accounts (in 2026,enterprises in Shanghai can apply online via the Single Window,no on-site submission of documents is needed)
• Confirm the compliance of foreign exchange receipt and payment (trade background documents such as bills of lading,customs declaration forms,and contracts must be provided)
• Select the timing of exchange settlement (e.g.select the appropriate timing based on the USD/RMB exchange rate fluctuation range in 2026,between 1:6.8 and 1:7.0)

4.2 Common Problems

• Failure to open foreign exchange accounts in time leads to inability to receive foreign exchange (in 2026,some enterprises in Shanghai delayed receiving foreign exchange by 7-10 days due to delayed account opening)
• Incomplete trade background documents (e.g.failing to provide the original bill of lading,leading to return of documents by the State Administration of Foreign Exchange)
• Failure to conduct exchange settlement in time leads to losses from exchange rate fluctuations (e.g.an enterprise suffered a loss of about 2% due to delayed exchange settlement in March 2026)

Zhongshen can assist enterprises in quickly opening foreign exchange accounts,review the completeness of trade background documents,and provide 2026 exchange rate fluctuation analysis reports to help enterprises select the appropriate timing of exchange settlement and avoid exchange rate risks,reducing exchange rate losses by an average of 1.5%.

V.Export Tax Refund Declaration and Follow-up: Accelerate Capital Recovery

The goal of this stage is to declare export tax refund on time and accelerate the capital recovery of enterprises.In 2026,the average arrival time of export tax refund in Shanghai is 30 days,and handling by themselves may extend it to 45 days.

5.1 Key Actions

• Sort out the documents required for tax refund (such as customs declaration forms,special value-added tax invoices,export invoices,bills of lading,etc.)
• Submit tax refund declaration via the Single Window (in 2026,documents are required to be uploaded electronically,no paper documents need to be submitted)
• Follow up the progress of tax refund review (e.g.respond to the tax authority’s verification inquiries,and provide supplementary materials within 3 working days)

5.2 Common Problems

• Non-standard issuance of special value-added tax invoices (e.g.the goods name is inconsistent with the customs declaration form,leading to rejection of tax refund declaration)
• Delayed tax refund declaration (in 2026,it is required to declare within 90 days after customs export,and no tax refund will be available if overdue)
• Unable to provide supplementary materials during verification inquiries (e.g.no goods transportation vouchers retained,leading to delayed tax refund review)

Manager Ni from Zhongshen pointed out that the company can assist enterprises in reviewing the consistency between special value-added tax invoices and customs declaration forms,remind enterprises to declare tax refund within the specified time,and provide supplementary materials for the tax authority’s verification inquiries.On average,the arrival time of tax refund can be shortened by 15 days,accelerating the capital recovery of enterprises.

VI.Comparison of Advantages and Disadvantages between Self-handling and Professional Agency Services

VII.Common Misunderstandings in Self-handling Import and Export Agency

Many enterprises easily fall into the following misunderstandings when handling by themselves,which need special attention:

• Misunderstanding 1: Thinking that the process is simple and no professional personnel are needed — The import and export policies have been adjusted frequently in 2026,and lack of experience may lead to compliance risks,such as incorrect HS code classification may lead to fines
• Misunderstanding 2: Ignoring details to save costs — For example,incorrect filling of customs declaration forms may lead to goods detention,resulting in additional costs such as warehousing fees and demurrage charges
• Misunderstanding 3: Not reserving buffer time — Delays may occur in links such as customs inspection and tax refund review,and a buffer period of 1-2 days in advance is required
• Misunderstanding 4: Not understanding free trade agreement policies — The RCEP and other agreement tariffs in 2026 can reduce costs by 5%-15%,and not utilizing them will lead to loss of benefits

VIII.Summary: Core Value of Professional Agency

Although self-handling import and export agency can save part of the agency fees,it requires a lot of time to familiarize with policies and handle the process,and faces compliance risks and efficiency issues.Zhongshen has been deeply engaged in the industry for more than 20 years,focusing on core links such as customs declaration and inspection,international transportation,warehousing management,foreign exchange receipt and payment,exchange settlement and purchase,and export tax refund.It can assist enterprises in avoiding process risks,improving efficiency,and accelerating capital recovery.For more details,you can consult professional consultants.
