What Are the Criteria for a Good Export Agency?

In 2026,Vietnam’s electronics market size exceeded USD 50 billion,and China’s export volume of smartphone accessories grew by 22% year-on-year.However,many enterprises suffered losses due to policy changes—Ms.Lu’s electronics factory in Shenzhen had a batch of charging cables exported to Vietnam detained by Haiphong Port Customs for 10 days last year because they failed to update the 4-digit extended code of the HS code on the RCEP certificate of origin in advance.This not only delayed the delivery date but also incurred an additional RMB 80,000 in storage fees.Similar situations often occur when exporting clothing and machinery to markets in the Middle East and Mexico: either inconsistent documents lead to customs clearance delays,or missing export tax refund materials slow down capital turnover.

Facing these pain points,choosing a reputable export agency has become the key.Take Shanghai Zhongshen as an example: it has been deeply engaged in the foreign trade agency industry for more than 20 years,focusing on core links such as customs declaration,inspection,customs clearance and export tax refund according to the trade policies of different target countries,and helping customers solve practical problems.Taking the export of electronic accessories to the Vietnamese market as an example,in 2026,Vietnam further reduced the tariffs on products from RCEP member countries to 0-3%,but required a certificate of origin with a 4-digit extended code,and electronic accessories must pass the compulsory product certification (CV).The core value of Zhongshen lies in sorting out these policy details in advance and customizing compliant service plans to help enterprises avoid pitfalls.

Targeted Responses to Core Export Agency Service Modules

1.Document Preparation: Meeting Vietnam-specific RCEP Policy Requirements

Vietnam has two new changes to the requirements for RCEP certificates of origin in 2026: first,the exporter must make an independent declaration; second,the certificate must include the 4-digit extended code of the product’s HS code.In addition,some Chinese electronic accessories are still on Vietnam’s temporary anti-dumping duty list.If the enterprise fails to provide an exemption certificate,it will need to pay an additional 5%-8% tariff.

Zhongshen’s response plan is to establish a Vietnamese document pre-review mechanism: the document team checks the 4-digit extended HS code 10 days in advance,connects to the certificate of origin system recognized by Vietnamese customs,and helps customers complete the independent declaration; for anti-dumping duties,it pre-checks whether the product is on the exemption list,and if so,marks the exemption number on the commercial invoice to avoid tariff losses.

2.Vietnamese Customs Clearance: Resolving Risks of the "Declare First,Inspect Later" Model

In 2026,Haiphong Port in Vietnam implemented the "Declare First,Inspect Later" model.If there are errors in the documents,re-declaration is required,with a delay rate of 15%; in addition,if the CV certification of electronic accessories expires,there is a direct risk of being returned.Ms.Lu’s factory had a 10-day delay due to re-declaration last year because of incorrect certificate of origin format.

Zhongshen’s response measures include: establishing long-term cooperation with local customs clearance agents in Vietnam to obtain port inspection dynamics in advance; establishing a CV certification tracking table to remind customers to renew 3 months before the certification expires,and coordinating temporary certification (product test report required) if customers are unable to renew on time.This year,the charging cables exported by Ms.Lu’s factory to Vietnam through Zhongshen had their customs clearance time shortened from 10 days to 3 days.

3.Export Tax Refund: Synchronizing Document Requirements of China and Vietnam

In 2026,China has new requirements for export tax refunds: RCEP certificates of origin must be provided as supporting documents; Vietnam’s export tax refund requirements require that the product names on VAT invoices fully match the customs declaration forms,and a copy of the bill of lading must be provided.Many enterprises have to wait up to 18 days for tax refunds to arrive due to inconsistent documents.

Zhongshen’s approach is: the document team prepares documents required for tax refunds in both China and Vietnam synchronously to ensure that product names are exactly the same; establishes a tax refund tracking system to submit applications within 1 working day after all documents are complete.In the first quarter of 2026,Mr.Dai’s Shanghai trading company shortened its tax refund arrival time from 18 days to 11 days through Zhongshen,improving capital turnover efficiency by 39%.

To clearly present the policy requirements and responses in the Vietnamese market,the following table sorts out the core points:

The reason Zhongshen can improve customs clearance efficiency and tax refund speed lies in two core experiences: first,localized service network,with long-term cooperation with customs clearance agents in markets such as Vietnam,the United Arab Emirates and Mexico,which can obtain policy updates in real time; second,digital document system,which automatically checks HS codes and invoice information to reduce manual errors.For example,in 2025,a clothing enterprise exported to the United Arab Emirates through Zhongshen,which applied for a quota certificate in advance,and its customs clearance time was 5 days faster than the industry average; in 2026,a machinery enterprise exported to Mexico,and its tax refund arrival time was 8 days faster than before.

For different target countries and products,Zhongshen’s service advantages also include:

• For clothing exports to the Middle East market,assist in applying for quota certificates and certificates of origin to avoid customs clearance delays caused by insufficient quotas
• For machinery exports to the Mexican market,sort out the rules of origin of the United States-Mexico-Canada Agreement (USMCA) in advance to help customers enjoy tariff preferences
• Provide one-stop services for foreign exchange receipt and payment,settlement and purchase to avoid losses caused by exchange rate fluctuations
