# Agent Export Goods Certificate Tax Declaration Process and Precautions

## 2026 Status of Tax Declaration for Export Agency of Vietnam’s Electronics Manufacturing Industry

In 2026,the RCEP regional trade integration process accelerates.Order volume of domestic electronic component enterprises exporting to Vietnam increased by 18% year-on-year,but many enterprises reported that they often get stuck in tax declaration for Agent Export Goods Certificate due to new policies of Vietnam Customs.For example,Vietnam fully implemented the Electronic Cargo Note (E-CN) in 2026,paper documents are no longer valid for customs clearance,and some enterprises failed to declare due to failure to switch systems in time.Meanwhile,the Vietnamese tax authority requires that electronic verification data from Vietnam Customs be provided simultaneously for export tax refund,applications will be directly rejected if data is inconsistent,and the tax refund cycle will be extended to more than 20 days.

### 1.Document Preparation Module: Strictly Comply with Vietnam’s E-CN Requirements

According to Vietnam’s 2026 new policy,the Agent Export Goods Certificate must be completely consistent with data in the E-CN system,and the RCEP Certificate of Origin (format must comply with the latest specifications of Vietnam Customs) must be provided.Zhongshen’s countermeasures include:

- Cooperate with local Vietnamese agents to obtain the latest updates of the E-CN system synchronously to avoid format errors;
- After generating electronic documents,automatically verify consistency with the Certificate of Origin and packing list,with a pass rate of 98%.

### 2.Customs Clearance Verification Module: Synchronize Vietnam Customs Data

- Complete electronic declaration of the Agent Export Goods Certificate 1 working day before customs clearance,and cooperate with Vietnamese agents to track verification status in real time;
- If data inconsistency occurs,coordinate with the document team to revise and re-upload within 1 hour to avoid port detention;

The Vietnamese tax authority requires in 2026 that export tax refund declaration must be provided with the Agent Export Goods Certificate,E-CN electronic data and foreign exchange receipt certificate at the same time,and the three must be completely consistent.Zhongshen’s advantages:

- Connect the domestic tax system with the data interface of Vietnam Customs to realize automatic data synchronization without manual repeated entry;
- Confirm receipt information in advance during the foreign exchange collection and payment process,and match with tax refund data to avoid application rejection caused by foreign exchange delay;
- The average tax refund cycle is shortened from the industry average of 15 days to 8 days,with the fastest arrival in 3 days.

## Practical Case of Zhongshen’s Service Efficiency Improvement

In March 2026,Ms.Wu from a Shanghai-based electronics enterprise entrusted Zhongshen to export a batch of capacitors to Vietnam.She originally planned to handle the tax declaration by herself,but the first declaration was rejected because she did not grasp the new requirements of Vietnam’s E-CN.After Zhongshen took over:

- Completed document pre-audit and E-CN format adjustment within 1 day;
- Uploaded the Agent Export Goods Certificate synchronously during customs clearance,and completed verification within 24 hours;
- Automatically synchronized Vietnam Customs data during tax refund declaration,and completed tax refund within 7 days.
