2026 Full Compliance Operation Guide for Vietnam Export Customs Declaration Agency

In 2026,China’s export trade volume to Vietnam increased by 7.2% year on year,with electromechanical equipment,hardware tools and chemical raw materials accounting for 63% of total exports.However,more than 40% of enterprises have encountered compliance problems in Vietnam export customs declaration procedures,including incorrect HS code classification,inconsistent certificate of origin and port detention delay.As a foreign trade agency headquartered in Shanghai,we rely on the national port linkage network and global customs clearance resources to provide enterprises with one-stop Vietnam export customs declaration solutions.

Core Service Modules of Vietnam Export Customs Declaration Agency

Port Declaration and Compliance Control

The core of Vietnam export customs declaration lies in accurate matching of HS codes and declaration elements.In 2026,Vietnam Customs upgraded its price verification model,and goods with declared price lower than the average price of the corresponding interval will trigger controlled inspection.Our team will assist enterprises in HS code classification based on the actual material,purpose and production process of goods,to avoid overpaid tariffs or fines caused by incorrect classification.In addition,we will pre-review information such as brand,model and specification in declaration elements to ensure consistency with physical goods and invoices,and reduce the probability of inspection.

In April 2026,we received the entrustment of an electromechanical enterprise in Suzhou,whose motors exported to Vietnam were placed under control by Shanghai Port Customs due to inconsistency between declared model and actual goods.Our team retrieved the original factory certificate of the goods immediately,submitted the situation explanation to the customs and corrected the declaration information.We completed the document modification and release in only 8 hours,avoiding 2 days of demurrage and a fine of CNY 12,000.

RCEP Tariff Reduction and Certificate of Origin Processing

Under the RCEP framework,Vietnam grants 0-5% tariff preferences to Chinese-origin goods on the premise that enterprises submit valid Form E Certificate of Origin.In 2026,Vietnam Customs strengthened the verification of Form E,focusing on checking third-party invoices and certificates of origin for entrepot trade goods.We will assist enterprises in reviewing invoice information to ensure that exporters and producers are consistent with the information on Form E,and complete the online pre-review of Form E 3 days in advance to avoid document rejection caused by incorrect information.

It should be noted that for entrepot trade goods,a complete certificate of origin chain is required,otherwise RCEP tariff preferences cannot be enjoyed.Our team will assist enterprises in sorting out trade links to ensure all documents meet the verification requirements of Vietnam Customs.

Export Tax Refund and Foreign Exchange Collection Security Guarantee

In 2026,the tax refund process for exports to Vietnam shall be completed through China International Trade Single Window,and enterprises need to submit documents including customs declaration forms,commercial invoices and Form E.Our team will pre-review all documents in advance to ensure consistent information,and avoid tax refund rejection caused by inconsistent documents.In addition,we will assist enterprises in completing online submission of tax refund declarations to speed up the tax refund arrival time,which is 3-5 days shorter on average than self-declaration by enterprises.

For foreign exchange collection security,we will assist enterprises in selecting compliant settlement methods including cross-border RMB settlement,to avoid exchange rate fluctuation risks.Meanwhile,we will monitor the foreign exchange collection path to ensure that the collection entity is consistent with the operating unit indicated on the customs declaration form,to avoid adverse impact on export tax refund.

Risk Early Warning and Emergency Handling

In 2026,the Ministry of Industry and Trade of Vietnam imposed temporary anti-dumping duties on some Chinese-made goods,including steel fasteners and some electromechanical products.Our global trade compliance system will push anti-dumping early warning information in real time,to assist enterprises in adjusting trade strategies in advance and avoid additional tariffs after goods arrive at the port.In addition,we have established an emergency handling mechanism.If goods encounter inspection or port detention,we can launch the emergency plan within 12 hours,and coordinate with port customs and local Vietnamese customs clearance agents to ensure fast release of goods.

• Incorrect HS code classification leads to overpaid tariffs or price verification queries.The document rejection rate caused by classification errors at Shanghai Port in 2026 increased by 9% year on year
• Inconsistency between Form E certificate of origin information and invoice leads to document rejection by Vietnam Customs,goods need to be returned or destroyed,with losses up to 30% of the cargo value
• Failure to declare packaging material or brand triggers customs controlled inspection,delaying customs clearance time by 2-3 days
• Inconsistency between foreign exchange collection entity and the operating unit on the customs declaration form leads to failure of export tax refund processing
