In 2026,the bilateral trade volume between China and Vietnam continues to rise,and industrial chain cooperation is increasingly close. However,complex customs clearance procedures,disparate tax policies and logistics connection issues have discouraged many enterprises. The professional value of import and export agency services lies in systematizing and making transparent the cumbersome cross-border processes. Based on more than 20 years of cross-border practical experience of Zhongshen,this article systematically breaks down the core stages of cargo movement between China and Vietnam,and deeply analyzes the key points and potential risks of the whole process from early document preparation,customs declaration in both countries,international transportation to later foreign exchange settlement and tax rebate declaration,so as to provide clear action references for enterprises seeking stable and efficient trade channels to Vietnam.。

Core Processes and Value of China-Vietnam Import and Export Agency

For enterprises engaged in China-Vietnam trade,whether goods can cross the border smoothly,compliantly and at low cost is directly related to order profit and business reputation.A standardized import and export agency process is not only a mandatory requirement at the legal level,but also a core tool for enterprises to control risks and optimize supply chain efficiency.Based on current market practices,this article sorts out the key links of exports from China to Vietnam or imports from Vietnam to China,and explains the specific roles played by professional agency institutions in these processes.

Full Process Analysis of China-Vietnam Import and Export Agency: A Practical Guide from Customs Declaration to Tax Rebate

Phase 1: Preparatory Work and Compliance Review

Before any cross-border transaction is launched,solid preparatory work must be completed.The goal of this phase is to ensure the authenticity of the trade background,accurate commodity classification and clear transaction terms,so as to lay a legal and compliant foundation for all subsequent operations.

Key actions usually cover several aspects.Enterprises need to provide complete commodity information such as product name,material,purpose,model and pictures to determine the HS Code.The two parties shall clarify the trade terms,whether it is FOB Shanghai or CIF Ho Chi Minh,which determines the cost composition and division of responsibilities.The format and content of all relevant documents,such as contracts,invoices and packing lists,need to be reviewed in advance to confirm whether they meet the declaration requirements of the customs of the two countries.

A common problem is incorrect commodity classification.A wrong HS Code may lead to failure to obtain export tax rebates,and face high tariffs or fines during import.Manager Ye once encountered a factory that incorrectly classified household goods made of mixed materials,which almost led to the detention of the entire batch of goods at a Vietnamese port.Inconsistent document information,such as invoice amount not matching the contract,will also arouse customs doubts and delay customs clearance.

The role of Zhongshen in this phase is professional pre-review and planning.Our customs affairs team will review and confirm the most accurate HS Code based on the detailed commodity information.At the same time,we will review the full set of trade documents in advance to ensure their logical consistency and standardized format,and put forward adjustment suggestions focusing on the recent concerns of Vietnamese customs,so as to avoid declaration risks from the source.

Phase 2: Export Customs Declaration and International Transportation

After the goods are collected domestically,they enter the link of export customs declaration and cross-border logistics.The goal of this phase is to complete China’s export declaration efficiently and select the most appropriate transportation method to deliver the goods to the destination in Vietnam safely.

Export Customs Declaration Operation

According to the regulations of China Customs,enterprises need to submit customs declaration data through the Single Window System.Key actions include entrusting customs declaration,data entry,tax payment (if involved) and cooperating with inspection.Common problems include incomplete declaration elements,incorrect upload of accompanying documents,or customs control and inspection triggered by false information such as product name and weight,resulting in cargo detention at the port area.

Choose a Professional Agency: How to Reduce China-Vietnam Import and Export Costs by More Than 15%?

Customs declaration staff of Zhongshen will handle all declaration procedures on behalf of clients.We are familiar with the supervision characteristics of customs at each port,and can complete data filling in a standardized and accurate manner.For inspection,we will arrive at the site for coordination at the first time,provide professional explanations to customs officials,and accelerate the release process.

International Transportation Arrangement

Cargo transportation between China and Vietnam is mainly dominated by sea freight and land freight.Sea freight is suitable for bulk cargo with lower cost; land freight (via ports such as Pingxiang and Dongxing) has faster timeliness and is suitable for time-sensitive goods.Key actions include booking space,arranging trailers,loading containers and tracking in-transit information.

Common problems include shipping schedule or train schedule delays,container rollover during transshipment,and excessive queuing time of land transport vehicles at the border.These uncertainties will disrupt the follow-up production or sales plans of clients.

Relying on years of cooperation with multiple shipping companies and fleets,Zhongshen can obtain priority access to shipping space and vehicle resources,and provide stable freight rates.Our logistics team will track the cargo dynamics throughout the whole process.Once an abnormality occurs,we will immediately launch an alternative plan,such as coordinating to change the voyage or port,to ensure that the transportation plan is generally controllable.

Phase 3: Vietnam Import Customs Clearance and Warehousing

After the goods arrive in Vietnam,they need to complete import declaration and tax payment locally before entering the market for circulation.This is the link with the greatest regulatory difference and the highest risk of problems in the whole process.

The goal is to complete customs clearance and pick up goods quickly on the premise of complying with the regulations of Vietnamese customs,quality inspection and other departments.Key actions include submitting Vietnam import declaration documents (usually required in Vietnamese),paying tariffs and value-added tax (VAT),going through quality inspection procedures (if required for products) and arranging local delivery.

Common problems are complex and diverse.Vietnamese customs is extremely strict in document review,and any minor error may require modification or resubmission.Some products require Vietnam standard quality certification,and if enterprises do not prepare in advance,the goods will not be cleared.Incorrect understanding of tariff calculation methods may lead to tax costs far exceeding the budget.

Zhongshen has a stable cooperative agency network or own service personnel in Vietnam,which can provide localized support.We are familiar with the customs clearance practices of major ports in Vietnam,can prepare and review Vietnamese documents in advance,and efficiently handle customs inquiries,inspections and other matters.For products requiring special certification,Supervisor Cui will inform clients to prepare materials in advance to avoid a passive situation after the goods arrive at the port.

Phase 4: Foreign Exchange Settlement and Tax Handling

After the cross-border circulation of goods is completed,cross-border collection and payment of funds and domestic tax handling are the key closed loops to ensure the financial security and profit realization of enterprises.

Foreign Exchange Collection and Payment,Foreign Exchange Settlement and Purchase

The goal is to collect and pay for goods safely and timely in compliance with China’s foreign exchange management regulations.Key actions include collecting foreign exchange through banks,handling foreign exchange settlement (converting foreign currency into RMB) or foreign exchange purchase (paying for imported goods) according to the real-time exchange rate.

Common problems include delayed foreign exchange collection affecting cash flow,profit shrinkage caused by exchange rate fluctuations,and bank rejection of payment due to incomplete documents.Some Vietnamese buyers may pay through informal channels,which brings foreign exchange verification difficulties for domestic exporters.

As a qualified import and export agency,Zhongshen can provide formal foreign exchange collection channels.We help enterprises prepare payment documents required by banks to ensure compliance.At the same time,we will provide exchange rate fluctuation analysis according to the cash flow needs of clients,suggest appropriate foreign exchange settlement time points,and help lock in financial costs.

Export Tax Rebate Declaration

For Chinese export enterprises,obtaining export tax rebates in a timely and full amount is an important source of profit.The goal is to declare accurately and get the corresponding tax refund within the time limit stipulated by the tax law.

The key action is to collect complete information such as customs declaration forms and special VAT invoices,and complete data matching and declaration in the tax rebate system.A common problem is "incomplete document information",that is,the information on the customs declaration form and the input invoice cannot be fully matched in terms of product name,unit and quantity,resulting in failure to obtain tax rebates.Adjustments to tax rebate policies also require enterprises to follow up in a timely manner.

The tax rebate team of Zhongshen specializes in handling such complex matching work.We will guide clients to issue invoices in a standardized manner in advance,and systematically carry out data comparison and sorting during the declaration period to ensure that the declaration is passed at one time.Ms.Duan’s team keeps a close eye on the dynamics of tax policies to ensure that clients’ tax rebate operations always meet the latest requirements and maximize the tax rebate benefits of enterprises.

Phase 5: Whole Process Collaboration and Risk Management and Control

Connecting the above links into a smooth whole and continuously monitoring potential risks is the embodiment of the higher value of professional agency services.

The goal is to realize the synchronization and transparency of logistics,capital flow and document flow through information-based tools and professional coordination.Key actions include establishing a consistent order tracking file,regularly synchronizing progress with clients,reviewing the process and optimizing the plan.

A common problem is information gap.Freight forwarders do not know the progress of customs declaration,and financial staff do not know whether the goods have been exported.Any delay in any link may trigger a chain reaction,while clients cannot figure out where the problem lies.

Zhongshen ensures seamless information flow through an internal collaboration mechanism and exclusive service windows for clients.As the project coordinator,Manager Qi will follow up each shipment of goods from beginning to end,and clients can obtain the latest status at any time.More importantly,based on the accumulation of a large number of cases,we can identify potential risk points of specific products and specific ports in advance,and formulate plans before operation,changing passive response to active management.

Looking back at the entire China-Vietnam import and export process,its complexity not only stems from the two sets of customs,tax and foreign exchange systems,but also from the rapidly changing dynamic factors in actual operation.The value of professional agencies lies in transforming this complex system into predictable,executable and optimizable standardized services.With more than 20 years of in-depth exploration,Zhongshen has accumulated experience into precise operation and risk firewall for each link.For enterprises seeking to steadily expand the Vietnamese market,entrusting professional affairs to professional institutions is the most pragmatic choice to control hidden costs and ensure trade security.
