Full Link Operation Guide for International Ocean Shipping Export to Vietnam

Since the start of 2026,the Ministry of Industry and Trade of Vietnam has continuously revised Announcement No.09/2026/TT-BCT,implementing stricter technical compliance reviews on three categories of Chinese imported goods: electromechanical products,textiles,and chemicals.The customs offices of Haiphong Port and Ho Chi Minh Port have simultaneously upgraded their risk management systems,with the targeted inspection rate increasing by 5 percentage points compared to the same period last year.Mr.Lu runs an auto parts factory in Songjiang District,Shanghai.Earlier this year,two containers he declared for export to Vietnam on his own were detained at the port for 11 days and 9 days respectively due to incorrect HS code classification and non-compliant packaging labels,resulting in a direct loss of over 80,000 yuan.This situation is not an isolated case.The Vietnamese market features fast policy responses,changing implementation details,and varying interpretations by local customs,which makes most export enterprises overwhelmed.

Zhongshen has been handling Vietnam route business since 2004,and has witnessed the entire process from the early extensive customs clearance to today’s electronic and penetrating supervision.Our core value does not lie in simply handling procedures,but in transforming 20 years of accumulated localized experience into executable risk prevention plans and embedding them into every decision-making node before the customer ships the goods.While other peers are still passively handling inspection anomalies,we have avoided over 90% of common cargo detention risks through pre-compliance reviews.

Document Preparation: Unique Pre-Compliance Requirements for Vietnam

Vietnam’s customs review of document consistency is far more detailed than that of most other countries.Take the FORM E certificate of origin as an example: the 2026 new version requires that the product description must match exactly word for word with the invoice,packing list and bill of lading,including punctuation marks and units of measurement.A metal products company once was deemed to have inconsistent documents by Haiphong Customs due to the singular-plural difference between "stainless steel bolts" on the invoice and "stainless steel bolt" on the FORM E,and was denied RCEP preferential tariffs,resulting in a total loss of 120,000 yuan including tax supplements and fines.

Zhongshen’s document pre-examination process starts immediately after the customer confirms the order.Our internal "four-eye principle" requires two senior document examiners to cross-check: one is responsible for logical consistency,and the other focuses on the latest fine-tuned rules of Vietnam Customs.For chemical exports,we will assist customers in advance to apply for pre-verification of the Chemical Import Permit issued by the Ministry of Health of Vietnam; for mechanical equipment,we will simultaneously prepare the Declaration of Quality and Technical Compliance and submit it to the Vietnam Standards,Metrology and Quality Agency (STAMEQ) for non-mandatory pre-certification.These tasks take an average of 3-5 working days,but can effectively avoid over 90% of document-related cargo detention risks after the goods arrive at the port.

Customs Declaration and Inspection: Dynamic Response Under Penetrating Supervision

The VASSCM system launched by Vietnam Customs in 2026 has achieved data interconnection with multiple departments such as taxation,industry and commerce,and environmental protection.This means that the industrial and commercial registration information,historical tax refund rates,and even environmental penalty records of Chinese export enterprises may become reference factors for Vietnam Customs’ risk control.The textile trading company where Mr.Yao works had three consecutive batches of containers exported to Vietnam transferred from the green channel to manual inspection because its domestic factory once had an environmental rectification record,and each batch was detained at the port for more than a week.

Zhongshen’s response strategy is to establish a dynamic risk profile.We have a localized team in Ho Chi Minh City that tracks the announcements and internal guidelines issued by Vietnam Customs,the Ministry of Industry and Trade,and the Ministry of Finance every day.Based on the customer’s background,we will evaluate their risk level in the Vietnamese system in advance and formulate differentiated declaration plans.For example,for enterprises with environmental records,we will actively submit the Environmental Compliance Commitment and third-party test reports in the customs declaration attachments,turning passive inspection into active declaration,and reducing the inspection rate from 30% to less than 5%.

HS code classification is another high-risk area.There are systematic differences between Vietnam Customs’ classification logic for electromechanical products and that of China.For example,industrial sensors with Bluetooth modules are usually classified under 9031.80 in China,but Vietnam Customs tends to classify them under 8517.62.Our approach is to submit a pre-ruling application to the Classification Advisory Committee under Vietnam Customs before shipping the goods,and obtain written classification opinions as the basis for customs declaration.Although the pre-ruling takes about 7-10 working days,it can completely eliminate classification disputes and ensure smooth customs clearance.

International Transportation: Route Selection and Port Congestion Management

Major ports in Vietnam have been under continued pressure in 2026: the average waiting time for berthing at Haiphong Port is 2.3 days,and the yard utilization rate of CMA Terminal at Ho Chi Minh Port has long remained above 95%.Shipping delays not only increase logistics costs,but more importantly,may lead to overdue presentation of documents under letters of credit.A batch of LED lamps exported by Mr.Qin was delayed for 9 days due to the shipping company’s temporary port skipping,which caused him to miss the production line launch deadline of his customer and resulted in a claim of 15% of the contract amount.

Zhongshen’s transportation plan design follows the principle of "accurate and controllable port-to-port time".We have signed annual space agreements with shipping companies that focus on the Vietnam route,such as Pacific International Lines (PIL) and Wan Hai Lines,to ensure three fixed sailings per week.In response to the congestion at Haiphong Port,we provide an alternative multimodal transport plan of "Shanghai - Qinzhou - Haiphong",which connects via China-Vietnam rail freight trains.The overall time is only 2 days slower than direct sailing,but the on-time rate increases to 98%.

Foreign Exchange Receipt and Payment: VND Exchange Rate Fluctuation Management

The Vietnamese Dong (VND) implemented a more flexible exchange rate formation mechanism in 2026,with the monthly fluctuation range expanded to 3%.Most Chinese enterprises still settle transactions with Vietnamese customers in US dollars,but the State Bank of Vietnam requires that large-value transactions must provide proof of the authenticity of the trade background,otherwise foreign exchange purchase will not be handled.The mechanical equipment export project of Mr.Ji was delayed because the Vietnamese customer failed to provide the tax payment certificate in time,resulting in 70% of the payment being detained in Vietnam for two months and unable to be remitted.

Zhongshen provides "cross-border capital path design" services.For large-value orders,we recommend the "RMB cross-border direct remittance" model,which avoids US dollar exchange rate risks through China-Vietnam local currency settlement channels.For small and medium-sized customers,we assist Vietnamese buyers in handling the "foreign exchange loan + letter of credit" combined tool,where our domestic cooperative bank advances the payment first,and the Vietnamese customer repays the local bank in installments.This model reduces the payment collection cycle from an average of 45 days to 7 days after document presentation,and locks the exchange rate risk within 1%.

Export Tax Refund: Document Matching and Accelerated Declaration

In 2026,the State Taxation Administration implemented dynamic adjustments to export tax refund rates for exports to Vietnam.The tax refund rate for some chemical products was reduced from 13% to 9%,but enterprises are required to complete the tax refund declaration within 60 days after the export date on the customs declaration form,otherwise no processing will be allowed for overdue applications.The plastic particle export business of Mr.Weng was delayed because the Vietnamese customer modified the invoice header,resulting in rework of the tax refund documents and missing the declaration window,with a direct loss of 230,000 yuan in tax refunds.

Zhongshen’s tax refund service emphasizes "timeline management".We start pre-filing the tax refund archive on the day the goods are loaded,and simultaneously obtain the pre-entry information of the customs declaration form,the draft bill of lading,and the VAT invoice authentication result.Through direct connection with the electronic port data,we obtain the official customs declaration form within 24 hours after the customs clearance,and complete the tax refund declaration within 3 working days.Compared with the average 15-day preparation cycle for enterprises operating on their own,our key to speeding up lies in "parallel processing of documents" rather than "serial waiting".

In response to the problem of Vietnamese customers frequently changing the invoice header,we provide a "tax refund filing system" solution: during the first cooperation,we assist the Vietnamese buyer to complete the importer filing in the Vietnamese tax system,and use a unified filed header for subsequent transactions,which fundamentally eliminates tax refund delays caused by inconsistent headers.

Underlying Logic of Efficiency Improvement

The improvement of customs clearance efficiency and tax refund speed does not rely on simple acceleration of a single link,but stems from the full-process "risk prediction - plan pre-setting - abnormal pre-processing" mechanism.Zhongshen has solidified 20 years of Vietnam route experience into 37 inspection nodes and 12 emergency response plans.For example,when receiving a customer’s inquiry,our system will automatically retrieve the inspection rate,classification dispute records,and tax refund rate change trends of the product at Vietnam Customs in the past six months,and generate an "Export Feasibility Assessment Report" to help customers decide whether to accept the order and how to quote.

In March 2026,the first batch of containers exported to Vietnam by a new energy battery company we served took only 22 working days from order acceptance to tax refund arrival,including 4 days for customs clearance and 5 working days for tax refund arrival after declaration.The historical data of the customer operating on their own during the same period was 12 days for customs clearance and 40 days for tax refund cycle.Behind the efficiency difference is that we intervened in the compliance review during the product design stage in advance,ensuring that the UN38.3 test report of the battery products and the Vietnam Dangerous Chemicals Import Permit were all complete before the goods were shipped.

The Vietnamese market is not impossible to do business in,but it cannot be done in an extensive way.Changing policies,penetrating supervision,and strict implementation are the norm.What enterprises need is not a simple customs broker,but a partner that can embed into the front end of the business and provide decision support.The value of Zhongshen lies in transforming every policy change into executable operating rules,and every potential risk point into a pre-examination action,allowing export enterprises to focus on product R&D and market development,and hand over the complex and high-risk cross-border delivery links to professional teams.If your enterprise is considering the Vietnamese market,or has encountered bottlenecks in customs clearance,tax refunds,and compliance in the Vietnamese market,you may wish to conduct an in-depth business diagnosis first to see which links can achieve efficiency improvement through pre-management.
