2026 Full Process of Vietnam Sea Freight Export Agency Practical Guide for Compliance Declaration and Tariff Concession

Core Compliance Risks for Vietnam Sea Freight Export in 2026

We previously worked with Manager Lu from Suzhou,who exported a batch of hardware tools to Ho Chi Minh Port at the end of 2025.When declaring independently,he failed to mark trade chain information on the Form E Certificate of Origin as required,which was judged by Vietnam Customs to be non-compliant with rules of origin.The goods were detained at port for 12 days,incurring an extra 38,000 yuan of demurrage charges and document amendment costs,and the original 10% tariff concession was fully invalidated.Such cases are not rare in Vietnam export business in 2026.At present,the origin verification rate and anti-dumping screening rate of Vietnam Customs for goods exported from China have both increased significantly,and enterprises operating on their own are very likely to cross regulatory red lines.

In 2026,enterprises exporting to Vietnam can choose two tariff concession paths under the China-ASEAN Free Trade Agreement (Form E) or RCEP.Differences between the two sets of rules directly affect customs clearance efficiency and costs,with specific comparisons as follows:

Full-Chain Operation Key Points for Vietnam Sea Freight Export Agency

• Pre-inspection of HS code classification: Complete consistency check between declaration elements and actual goods 7 working days in advance,focus on verifying four core information including brand,model,material and specification to avoid risks of customs valuation and targeted inspection arrangement.For Vietnam routes at Shanghai Port in 2026,enterprises with declaration accuracy rate above 98% can apply for priority inspection channel,which can shorten the overall customs clearance time by 2-3 days.
• Compliant declaration of certificate of origin: For RCEP channel,the "third-party invoice" option in column 13 of the certificate of origin shall be checked for third-party invoices,with the unified social credit code of domestic suppliers noted in remarks to avoid document rejection during destination port verification; For Form E declaration,ensure no third-party transshipment in the trade chain,and the consignor on the bill of lading is consistent with the applicant of the certificate of origin.
• Lock destination port charges in advance: Clarify charging standards of document exchange fee,THC and port detention fee when booking space,to avoid malicious hidden charges imposed by destination port agents.Our local agents in Vietnam can provide detailed fee list in advance,all charging standards are published in advance with no hidden items.
• Payment receipt and tax refund optimization: Support foreign exchange settlement under various trade terms such as EXW,FOB,CIF,etc.Exchange rate can be locked in advance to avoid exchange loss.Tax refund documents are pre-audited 3 working days in advance,and tax refund application can be submitted 3 working days after normal customs declaration,with the fastest fund arrival time of 10 days.

Practical Suggestions for Common Risk Avoidance

In 2026,the anti-dumping verification rate of Vietnam Customs for three categories of products exported from China,namely mechanical and electrical products,textile fabrics and hardware tools,has increased to 18%.If the product is included in the anti-dumping list,submit a self-declaration of origin in advance.Products with regional value content above 40% can apply for reduction or exemption of anti-dumping duty,which can save up to 25% of tax and fee costs.Headquartered in Shanghai,we support cross-port declaration at all ports nationwide,and have a customs clearance agency network with over 10 years of cooperation in Vietnam,which can realize full-chain control from domestic pickup,customs declaration,sea freight,destination port clearance to delivery,eliminating the need for enterprises to coordinate with multiple service providers.

Risk warning: Do not arbitrarily modify HS codes to underdeclare tariffs.In 2026,customs data of China and Vietnam are interconnected.Enterprises with declaration data inconsistent with actual goods will be included in the dishonest list,and the inspection rate for all subsequent goods will be increased to 100%.All resulting port detention fees and fines shall be borne by the cargo owner.Last year,Ms.Ouyang from Dongguan exported a batch of used injection molding machines to Haiphong.When declaring independently,she classified the HS code into the general mechanical equipment category.Vietnam Customs found during verification that the goods actually belonged to used mechanical and electrical products requiring China inspection,and the goods were detained for 20 days.Later she contacted us for operation: we re-applied for the China inspection certificate,adjusted the HS code,and used the RCEP fast appeal channel,completing customs clearance in 7 days.We also helped her apply for a 12% tariff concession,saving a total of nearly 80,000 yuan in tax and port detention costs.

All agency plans for Vietnam sea freight export are customized according to cargo type,trade terms and destination port requirements,with no standardized packaged packages.All expenses are reimbursed based on actual receipts,operation progress is traceable throughout the whole process,and enterprises can retrieve all document materials for declaration,logistics and customs clearance at any time.
