Should Export Agency Enterprises File Declarations? Analysis of 2026 Practical Key Points

Export of Electronic Products to Vietnam: 2026 Market Background and Declaration Challenges

Data for the first quarter of 2026 shows that China’s export value of electronic products to Vietnam increased by 18.7% year-on-year,making Vietnam one of the core target markets for China’s electronic product exports.Ms.Xiang,Manager of the Documentation Department at Zhongshen,noted that many enterprises encounter difficulties in export declaration: Vietnam Customs has tightened the review of technical parameters of electronic products,errors in filling out the certificate of origin can easily lead to higher tariffs,and some enterprises unfamiliar with the operation of the local "single window" face problems such as delayed document submission and port detention during customs clearance.

Core Value of Zhongshen Export Agency Services: Precisely Align with Vietnam’s Policies

Mr.Xing,head of an electronic product export enterprise in East China,once paid an extra 12% tariff because the preferential clause of the "Vietnam-China Free Trade Agreement" was not marked on the certificate of origin when he declared on his own.After choosing Zhongshen as the agent,Ms.Xiang’s team pre-audited the documents in advance and helped him enjoy the FTA tariff rate,reducing the cost of each shipment by nearly RMB 30,000.Zhongshen has been deeply engaged in foreign trade agency for 20 years.In response to Vietnam’s 2026 import policy adjustment,its core value is reflected in "precise policy alignment + full process control": it not only helps enterprises complete declaration,but also avoids local unique compliance risks.

1.Documentation Module: Vietnam’s Unique Policy Requirements and Responses

Vietnam Customs clearly stipulated in 2026 that export declarations for electronic products must include three types of core documents,each with local unique review standards:

• Certificate of Origin (FORM E): It is required to mark the product as "wholly produced" or "regional value content ≥ 40%".Some enterprises fail to provide raw material procurement vouchers,resulting in invalid certificates;
• Product test report: It must comply with Vietnam’s QCVN10-2:2025/TT-BCT standard,covering 12 indicators including electromagnetic compatibility and safety performance;
• Electronic ledger: It must be connected with Vietnam’s "National Single Window" system in real time,and the data must include 18 parameters such as product model,HS code and production batch.

Zhongshen’s response plan: The documentation department has set up a "special pre-audit post for Vietnam".Ms.Xiang’s team will complete document verification 3 working days before declaration.For QCVN standards,they will coordinate with local Vietnamese certification institutions (such as the Vietnam Standard and Quality Certification Center) in advance to ensure the compliance of test reports; for the electronic ledger,a template connected with Vietnam’s single window has been developed to automatically match 18 parameters and avoid manual filling errors.

2.Customs Clearance Module: Risks and Responses after the Upgrade of Vietnam’s "Single Window"

In 2026,Vietnam Customs upgraded its "National Single Window" system,requiring that declaration data go through the initial customs review within 24 hours after submission.If parameters do not match,the system will automatically trigger inspection,and the inspection rate has increased by 8.2% compared with 2025.Ms.Xiang mentioned that an enterprise once had its goods detained at Ho Chi Minh Port for 5 days due to an incorrect HS code (misclassifying "portable Bluetooth speakers" as "other audio equipment"),resulting in container detention fees of nearly RMB 20,000.

Zhongshen’s customs clearance responses:

• Enter pre-declaration data 72 hours in advance,the customs clearance team monitors system feedback in real time,and completes data correction within 1 hour if a "parameter warning" occurs;
• Establish a regular communication mechanism with the customs inspection departments of Vietnam’s Ho Chi Minh Port and Haiphong Port,arrange exclusive translators for the review of technical parameters of electronic products to avoid inspection delays caused by poor communication;
• Provide "green channel" declaration services for high-value electronic products,with priority for customs review.

3.Tax Refund Module: Declaration Key Points and Efficiency Improvement under the Sino-Vietnamese Tax Agreement

After the update of the Sino-Vietnamese tax agreement in 2026,export tax refunds need to meet two core conditions: first,the customs declaration form is synchronized with the electronic data of Vietnam Customs in real time,and second,the foreign exchange verification form must be marked with "foreign exchange receipt under the Vietnam Free Trade Agreement".Manager Miao,Head of the Tax Refund Department at Zhongshen,noted that some enterprises had their tax refund applications rejected by the tax authority because the foreign exchange verification form did not mark the FTA clause,with an average delay of 22 working days.

Zhongshen’s tax refund responses:

• Establish a "customs - tax authority - bank" data synchronization mechanism,and complete electronic data docking with China’s tax system within 12 hours after the customs declaration form is submitted;
• The foreign exchange collection and payment team reviews foreign exchange receipt vouchers in advance and marks FTA clauses to ensure the compliance of the verification form;
• Open the "tax refund express channel" for electronic product export enterprises,shortening the average tax refund time to 15 working days,7 days faster than the industry average.

Enterprise Self-Declaration vs Zhongshen Agency: Core Data Comparison

Mr.Xing said that after choosing Zhongshen as the agent,the customs clearance time of his enterprise was shortened from 6 days to 2 days,the tax refund speed increased by 40%,and the annual cost savings on port detention fees,tariffs and other items exceeded RMB 150,000.

Customized Services: Matching Needs of Different Products and Target Countries

In addition to Vietnam,Zhongshen provides customized agency services according to different trade policies of other Southeast Asian countries (such as Thailand,Malaysia) and European countries (such as Germany,the Netherlands).Mr.Miao,Head of the Marketing Department at Zhongshen,noted that for mechanical equipment exported to Germany,CE certification and energy efficiency labels will be reviewed as key items; for textiles exported to Thailand,the FORM E certificate of origin will be processed in advance to ensure the enjoyment of FTA tariff rates.

When choosing an export agent,foreign trade enterprises should select service providers with local policy experience based on their own product types and target country policies.Zhongshen has been deeply engaged in the industry for 20 years,covering trade policies of more than 30 countries around the world,and can provide accurate declaration solutions for different enterprises.
