Which China-Vietnam Import & Export Agent to Choose? 2026 Full-link Service Guide for Customs Declaration, Tax Refund and Logistics

Last month,we received a hardware tools client from Zhejiang that was connected to Manager Mu.Previously,the client cooperated with a small local agent for shipment to Vietnam’s Haiphong Port,but encountered wrong HS Code classification.The client not only failed to enjoy RCEP tax reduction,but also paid an extra 12% import tariff,with the cargo detained for 14 days.The demurrage fee alone cost nearly 20,000 RMB.Such issues are very common in China-Vietnam trade,as many enterprises are unfamiliar with Vietnam’s customs clearance rules and RCEP policies,and easily fall into various traps.

Core Compliance Requirements and Common Pitfalls for China-Vietnam Import & Export in 2026

In 2026,Vietnam Customs upgraded its inspection system,raising the controlled inspection rate for goods imported from China by 17% compared with 2025,and significantly tightened requirements on declaration element consistency and document completeness.Customs clearance requirements vary greatly across product categories.We sort out the comparison of latest core requirements as follows:

The core reason why many enterprises fall into traps is inconsistent documents.For example,the declared brand is unbranded while actual goods carry brand logos,or the declared model is wrong.Once detected by Vietnam Customs,the goods will at least be detained for rectification,with a fine equal to 10%-30% of the cargo value.In worse cases,the enterprise will be blacklisted by customs,and all its subsequent goods will face 100% inspection.

Practical Pit Avoidance Suggestions and Risk Warning

With years of experience in China-Vietnam trade,I have seen many enterprises suffer huge losses due to lack of understanding on relevant rules.Here I share two core pit avoidance suggestions for you:

The first is never forge Certificate of Origin for tax reduction.In 2026,the customs of China and Vietnam have realized real-time interconnection of Certificate of Origin data,and the authenticity can be checked once verification is conducted.Once detected,you will not only need to make up the full amount of tariff,but also pay a fine twice the tariff amount.Meanwhile the enterprise will be included in the dishonesty list,and all subsequent import and export businesses will be subject to intensified supervision.

The second is to be alert to hidden cost traps.Many small agents only quote basic freight and customs declaration fees,but charge extra fees for document exchange,port demurrage,expedited customs clearance and other items after the goods arrive at the port.The total final cost will be more than 2 times the original quotation.We will list the detailed breakdown of all fees in advance,with zero hidden charges,and all charging standards are specified in the contract.

Headquartered in Shanghai,Zhongshitong leverages the resource advantages of Shanghai as an international trade center to realize off-site customs declaration at all ports nationwide.No matter you are located in the Yangtze River Delta,Pearl River Delta or Bohai Rim region,you can access our services without looking for local agents.All procedures can be tracked online with full information transparency.

Reference of Real Service Case

In March this year,we received a textile client from Suzhou,Jiangsu.The client previously handled China-Vietnam import and export by itself,and had to wait for more than 3 months for each export tax refund.It once failed to enjoy RCEP tax reduction due to non-compliant Certificate of Origin,resulting in a loss of nearly 60,000 RMB.After taking over the service,Manager Mu first reclassified the HS Code for their products to ensure compliance with both domestic tax refund and Vietnam tax reduction requirements.We pre-review all documents before each shipment,apply for RCEP Certificate of Origin,and coordinate with local Vietnam teams for priority customs clearance.Over the 6-month cooperation period,the client’s tax refund lead time has been shortened to 21 days,and a total of 87,000 RMB has been saved through RCEP tax reduction,with no cargo detention or port demurrage incidents.

If your enterprise has demands for China-Vietnam import and export,you can apply for free HS Code classification and cost estimation first,to pre-exclude all potential risks and ensure full compliance and high efficiency of the whole service link.
