Full Process of Local Vietnam Import Agency: Practical Guide to Customs Valuation and Commodity Inspection Pre-Audit

Local Vietnam Import Agency: Practical Operation Framework from Customs Declaration to Clearance

In 2026,Vietnam’s manufacturing output accounted for 26.3% of its GDP,and demand for exports to China of categories including electronics,textiles and furniture increased significantly.As a frontline agent at Zhongshitong’s Shanghai headquarters,I have assisted more than 30 small and medium-sized Vietnamese factories with export agency services to China,among which 80% of enterprises encountered problems such as mismatched declaration elements and inspection delays during their first import.Starting from core customs links,the following breaks down key compliance and risk control points for local Vietnam import agencies.

1.Customs Valuation and Price Declaration: 3 Practical Pitfall Avoidance Points

Customs valuation is the core threshold for import agencies.The latest Valuation Measures issued by the General Administration of Customs in 2026 clearly require declared prices to meet the principle of "actually paid or payable transaction price".Common risk points and countermeasures are as follows:

• Risk scenario: Vietnamese suppliers quote under EXW terms,which only includes ex-factory price and excludes local Vietnam land freight,leading to an under-declared total price that triggers customs queries.
  Zhongshitong operation: Sign the Vietnam Domestic Transportation Service Agreement in advance,clarify that land freight and port miscellaneous fees are borne by the Chinese side,mark "including domestic freight" in the invoice remark column,and submit the original waybill issued by the Vietnamese logistics provider simultaneously.
• Risk scenario: Chemical products are declared as "plastic particles",but customs finds they are actually "modified plastics" (HS Code 39139000),resulting in supplementary tax payment due to a 3% tax rate difference.
  Zhongshitong operation: Require Vietnamese factories to provide a Product Composition Analysis Report (which must include information on whether plasticizer is contained and types of modifiers),and complete pre-classification through the AEO certification system 48 hours before import.
• Risk scenario: Electronic products are declared at FOB price,but are actually transshipped via Vietnam-Hong Kong trade,leading to a 15% difference between the declared FOB price and actual transaction price.
  Zhongshitong operation: Mandatorily require Vietnamese exporters to provide a Non-Transshipment Trade Declaration,noting that "goods are of Vietnamese origin and have not been processed/assembled in a third country",and attach the Export Clearance Form issued by Vietnamese customs as supporting evidence.

2.Commodity Inspection Pre-Audit and Animal & Plant Quarantine: Special Handling for Two Types of Sensitive Products

Imports from Vietnam need to be divided into general cargo and regulated goods.Animal and plant-derived products,cosmetics and other such goods require special quarantine completed in advance:

• General cargo (such as hardware tools): Three-document matching (bill of lading,invoice,packing list) must be completed 72 hours before the goods arrive at the port,to ensure declaration elements are consistent with actual goods (including brand,model and material).Shanghai Port launched the Declaration Element AI Verification System in 2026.If the brand and model do not match the actual goods,the system will automatically intercept the declaration.
  Practical suggestion: Upload the product nameplate photos provided by the Vietnamese factory to the Single Window in advance.After passing system verification,manual inspection can be exempted.
• Regulated goods (such as leather products,wooden furniture): The Phytosanitary Certificate issued by the Vietnamese Ministry of Agriculture must be submitted,and the certificate must indicate that "no wood from epidemic areas is used in processing".Zhongshitong once handled a case where a Vietnamese furniture factory’s goods were detained at Yangshan Port for 5 days because the certificate did not note "non-epidemic area pine",and the goods were finally released after submitting a CCIC certificate and supplementary epidemic area certification.
  Key reminder: Leather products require additional chromium content inspection (EU standard ≤3mg/kg).The electronic supervision code filing requirement was added in 2026,which must be completed 3 working days in advance.

3.Import License and Form E Certificate of Origin: Correct Way to Access RCEP Tariff Dividends

As an RCEP member state,Vietnam can enjoy tariff reductions with Form E certificates of origin (average tariff reduced from 9.8% to 5.2%),but the General Administration of Customs notified multiple cases of document rejection caused by third-party invoices in 2026:

In addition,for categories involving automatic import licenses (such as Vietnamese rice added to the list in 2026),applications must be submitted to the Ministry of Commerce 15 working days in advance.Zhongshitong can assist enterprises in applying for state-owned trade quotas to avoid rejection due to insufficient qualifications.

4.5 Hidden Costs of Local Vietnam Import Agency and Risk Control Suggestions

• Demurrage trap: Vietnam port’s 24-hour free storage policy only applies to goods directly shipped to China.Transshipment via Hong Kong/Singapore will trigger combined demurrage and storage fees.It is recommended to choose direct shipping lines from Vietnam to Shanghai (such as COSCO Shipping’s Vietnam-China route),which can save about USD 1200 per container in demurrage fees.
  Operation tool: Use the sea freight booking system to track vessel ETA in real time,and send the Entry Customs Declaration Form to the Vietnamese agent for filing 2 days in advance.
• Switch bill fee dispute: Bundled charging of switch bill fee and amendment fee is common in Vietnamese ports.A chemical enterprise was once charged USD 300 in amendment fees by the agent because it failed to check the order bill of lading clause of the sea waybill.
  Preventive measure: Require the Vietnamese agent to provide a Bill of Lading Issuance Process Confirmation Letter,clarify whether bill amendment requires shipowner confirmation,and retain the Vietnamese port’s fee detail list.
• Exchange rate fluctuation risk: The exchange rate of RMB against Vietnamese dong fluctuated by ±4.2% in 2026.It is recommended to use forward foreign exchange settlement and sales to lock the exchange rate.The Shanghai Branch of Bank of China,Zhongshitong’s cooperative bank,can provide real-time VND/RMB exchange rate quotations.
• Customs inspection delay: The inspection rate of Shanghai Port decreased by 15% year-on-year in 2026,but under-declared goods and sensitive categories are still likely to trigger inspection.It is recommended to submit the Inspection Risk Assessment Report 24 hours before import,highlighting the consistency between declaration elements and actual goods.
• Origin verification: Customs of RCEP member states will conduct 100% electronic verification of Form E certificates.If insufficient evidence of substantial transformation is found (e.g.only the packaging process is completed outside Vietnam),a fine of 50% of the tax amount will be imposed.
  Zhongshitong solution: Require the Vietnamese factory to provide production process records,clarify that key processes (such as welding,heat treatment) are completed in Vietnam,and attach process certificates such as infrared temperature measurement reports.

5.Differentiated Service Capabilities of Zhongshitong at Shanghai Port

Relying on 20 years of frontline experience,Zhongshitong has built three core advantages in the field of Vietnam import agency:

• Cross-regional declaration at national ports: It can cooperate with 12 direct customs offices including Shanghai,Ningbo and Shenzhen to realize "one declaration,clearance at multiple ports",and avoid goods detention during transshipment caused by mismatched declaration elements.
• Global agency network collaboration: It has 3 direct liaison offices in Ho Chi Minh,Hanoi and Haiphong,providing 24/7 response to demands including local Vietnam customs declaration,land transportation connection and port warehousing.
• Risk pre-control system: It has established a three-dimensional matching model of "HS Code - declaration elements - inspection probability",which can provide early warning of declaration risks for high-risk goods (for example,3D printing consumables added to the regulatory list in 2026 require additional MSDS reports).

The essence of local Vietnam import agency is precise control of compliance costs.Whether it is setting price anchor points for customs valuation,or building the origin evidence chain for Form E certificates,it requires deep integration of policy interpretation ability and practical operation experience.Zhongshitong always believes that the value of a professional agency is not only to complete the customs declaration process,but also to help enterprises avoid compliance costs caused by information asymmetry.
