# Efficient and Reliable Export Agency Service, Solving Enterprises' Overseas Customs Clearance and Tax Refund Problems

## Market Background and Common Challenges of Electronic Product Export to Southeast Asia

In 2026,many electronic product enterprises in Shanghai have targeted the Southeast Asian market,where the annual demand growth of smartphones and smart home products exceeds 12%.The small home appliance enterprise that Ms.Ren works for saw its export orders to Vietnam increase by 30% in 2025 compared with the previous year.However,many enterprises report that they encounter many pain points in export: order rejection due to inconsistent documents,customs clearance delay of more than 3 days,long tax refund cycle and other problems occur frequently — Ms.Ren’s enterprise once suffered 5 days of cargo detention at the port because Vietnamese customs required additional documents for CE certification,resulting in a loss of nearly 20,000 RMB.

Trade policies vary greatly among Southeast Asian countries.For example,Vietnam’s tariff rates for smart products range from 8% to 12%,and some products also need to provide test reports in Vietnamese; Thailand requires pre-declaration 7 days before cargo arrives at the port,otherwise port detention fees will be incurred.If these details are not handled properly,export efficiency can be easily affected.

## Core Value of Zhongshen’s Export Agency Service

Zhongshen has been deeply engaged in foreign trade for more than 20 years.In view of the policy characteristics of the Southeast Asian market,we do not provide general agency services,but focus on core links including customs declaration and inspection,international transportation,warehouse management,foreign exchange receipt and payment,foreign exchange settlement and purchase,and export tax refund.We sort out the compliance list of each country in advance,helping enterprises reduce unnecessary detours by 30%.For example,in response to Vietnam’s preferential tariff policy,Zhongshen will help enterprises apply for FORM E Certificate of Origin,reducing the tariff from 10% to 5%,saving nearly 10,000 RMB in cost per single order.

## Breakdown of Core Service Modules of Export Agency for Southeast Asian Market

### 1.Target Market Policy Comparison: Requirement Differences of Core Southeast Asian Countries

| Country/Region | Import Tariff Rate for Electronic Products (2026) | Mandatory Document Requirements | Regular Customs Clearance Lead Time | Special Barriers |
| --- | --- | --- | --- | --- |
| Vietnam | 8%-12% (smart products enjoy 5% preferential tariff rate) | Commercial Invoice (Bilingual English-Vietnamese),Packing List,CE Certification (with additional instructions approved by Vietnam Ministry of Industry and Trade),FORM E Certificate of Origin | 3-5 working days | Some ports require copy of product test report |
| Thailand | 10%-15% (smart home products enjoy ASEAN free trade preference) | Commercial Invoice,Packing List,CB Certification,FORM E Certificate of Origin,Cargo Pre-declaration Form | 2-4 working days | Electronic pre-declaration must be submitted 7 days before arrival at port |
| Malaysia | 7%-10% (some smart devices are zero-tariff) | Commercial Invoice,Packing List,SIRIM Certification,FORM E Certificate of Origin | 2-3 working days | Product environmental protection test report is required |

### 2.Document Compliance Module: Breaking Language and Certification Barriers

Southeast Asian countries have strict language requirements for documents.Vietnamese customs requires all documents to be provided in both English and Vietnamese versions.Ms.Ren’s enterprise was rejected twice last year due to inaccurate translation.Zhongshen’s document team cooperates with local Vietnamese translators who are familiar with the terminology specifications of the Ministry of Industry and Trade,ensuring that additional instructions for CE certification meet the latest requirements.

In addition,Zhongshen will review all documents 3 working days before cargo customs declaration,including whether the commodity code on the invoice matches the HS code used in Thailand,and whether the SIRIM certification for Malaysia is still valid.For the 12 enterprises served in the first half of this year,the document rejection rate dropped from the industry average of 18% to 3%.

### 3.Customs Clearance Execution Module: Optimizing Process According to Port Differences

- Cooperate with designated customs brokers at Haiphong Port (Vietnam) and Laem Chabang Port (Thailand),obtain port congestion warnings in advance and adjust cargo arrival time — for example,when Haiphong Port was congested due to typhoon in March 2026,Zhongshen redirected 3 shipments to Ho Chi Minh Port to avoid delay;
- For Thailand’s pre-declaration requirements,we arrange dedicated personnel to submit electronic data 5 days before cargo departure,ensuring direct customs clearance after arrival.This year,the customs clearance lead time of Thai orders we served is 2 working days faster than the industry average;
- We provide 24-hour emergency response for customs clearance.Last year,when the cargo of Mr.Xia’s enterprise was subject to temporary random inspection by Vietnamese customs,Zhongshen supplemented all required test reports within 3 hours,and no port detention occurred.

### 4.Export Tax Refund Module: Matching Tax Refund Rhythm for Southeast Asian Market

In 2026,the average industry tax refund cycle for electronic products exported from Shanghai to Southeast Asia is 15-20 working days,but some enterprises are delayed due to inconsistency between documents and customs declaration data.Zhongshen’s tax refund team adopts the "pre-matching before declaration" mode: before cargo customs declaration,we check the invoice and packing list against the data in the tax refund system to ensure the commodity code and amount are consistent;

At the same time,Zhongshen connects to the green channel of the tax authority,enabling priority review for enterprises exporting to Southeast Asia.This year,the tax refund cycle of served enterprises is shortened to 8-12 working days,40% faster than the industry average.After the smart speaker enterprise that Mr.Huo works for chose Zhongshen last year,the tax refund speed was shortened from 18 days to 9 days,and the capital turnover efficiency increased by 50%.

## Key Experience of Zhongshen in Improving Efficiency

Zhongshen has 2 local coordinators in Vietnam and Thailand respectively,who update policy changes in real time — for example,when the Ministry of Industry and Trade of Vietnam adjusted the requirements for additional instructions of CE certification in May 2026,the local coordinator notified the client on the same day,avoiding document errors.

In addition,Zhongshen has established a "document-customs clearance-tax refund" data sharing system,where the progress of each link is synchronized in real time to avoid information gap.For emergencies (such as customs policy adjustment,port congestion),we send warning notifications to clients 3 days in advance.Since the beginning of this year,the customs clearance efficiency of served enterprises has increased by 35%,and the tax refund speed has increased by 40%.

## Customized Service: Matching Needs of Different Products and Target Countries

Whether it is small home appliances,smartphones or smart home products,and whether the target country is Vietnam,Thailand or Malaysia,Zhongshen can customize exclusive export agency solutions according to the enterprise’s product characteristics and target country policies.For example,in response to Malaysia’s environmental testing requirements,Zhongshen will help enterprises connect with local testing institutions in advance to ensure the report meets requirements.

For the export orders to Vietnam of Mr.Huo’s smart speaker enterprise last year,Zhongshen helped it apply for the 5% preferential tariff and optimized the customs clearance process,reducing the cost per single order by 8% and shortening the customs clearance time by 4 days.Such efficiency improvement is exactly the confidence of Zhongshen after 20 years of deep cultivation in foreign trade.
