Zhongshen: 20 Years of Practical Experience Summary of China Export to Vietnam Agency Services

Vietnam Market Background and Practical Challenges for Export Enterprises

In 2026,Vietnam continues to maintain its position as the most important re-export and terminal market for China in the global supply chain.The container volume of electronic components,mechanical equipment,textile raw materials,and chemical products shipped to Ho Chi Minh City and Hai Phong Port has maintained stable year-on-year growth.The Kunshan electronic component factory where Ms.Yao works recently encountered a problem: a batch of integrated circuit boards was detained by Hai Phong Customs for two weeks due to HS code classification disputes,incurring additional storage fees and almost missing the customer’s production line scheduling.Such scenarios are not uncommon among Yangtze River Delta export enterprises trading with Vietnam.The electronic customs declaration system V5.0 launched by the General Administration of Customs of Vietnam at the end of 2025 has extremely high requirements for digital document matching.Minor adjustments to the certificate of origin format,or discrepancy in decimal places between the commercial invoice amount and the customs declaration form,can all trigger manual inspection.More complicatedly,the 2026 edition of the Import License Management Catalogue released by the Ministry of Industry and Trade of Vietnam has included 53 categories of goods under control,including some lithium batteries and photovoltaic modules.If enterprises fail to apply for the license 60 days in advance,the goods will face the risk of return upon arrival at the port.

Core Value of Zhongshen’s Export Agency Service

Zhongshen has been deeply engaged in export agency services in Shanghai Pudong Waigaoqiao Free Trade Zone for more than 20 years,and cargo handled on Vietnam routes accounts for 40% of its total annual cargo volume.Its core value is not simply handling documentation errands,but converting the fragmented policies from Vietnam’s Ministry of Industry and Trade,General Administration of Customs and General Department of Taxation into executable operation checklists.For Ms.Yao’s integrated circuit board shipment,Zhongshen’s customs affairs team completed pre-classification within two hours after accepting the order,submitted a classification pre-ruling application to Hai Phong Customs,and obtained customs clearance approval before the goods arrived.This proactive risk intervention is the essential difference between a professional agency and an ordinary freight forwarder.Zhongshen’s Hanoi office has established a co-working mechanism with local customs brokers,allowing goods in the yellow channel to complete supplementary document submission within 6 hours.For red channel inspection,it arranges pre-loading supervision photography and seal number filing in advance,improving inspection efficiency by 40%.

Document Pre-audit and Compliance Construction Module

Vietnam’s import documentation system still has its own particularities under the RCEP framework.Starting from 2026,Vietnam Customs has adjusted the tax exemption threshold for low-value goods to 2 million Vietnamese Dong,but requires an electronic certificate of origin E-Form D to be attached.Zhongshen’s documentation department establishes a digital file for each shipment,and automatically compares the shipper,consignee,and cargo description with the historical inspection records in Vietnam Customs’ database.In Ms.Yao’s case,the system warned that her Vietnamese consignee had three previous rejection records due to inconsistent invoice title,and required the other party to update business registration information in advance,avoiding repeated errors.For goods requiring an import license,Zhongshen’s policy research team updates the license application progress database every week,informing customers which commodities need to apply 60 days in advance,and which can complete customs clearance first with a letter of guarantee.

Customs Clearance Execution and Exception Handling Module

Vietnam Customs implements a three-color channel system: green for automatic release,yellow for document verification,and red for physical inspection.In the first quarter of 2026,the random inspection rate of the yellow channel at Ho Chi Minh Port rose to 18%,mainly targeting sensitive categories such as chemical products and medical devices.Zhongshen’s countermeasures include: First,complete the classification pre-ruling with Vietnam Customs before cargo loading to ensure the HS code is correct; Second,adopt the split declaration strategy for high-risk goods to avoid the entire shipment being detained; Third,sign a priority service agreement with the inspection station designated by Vietnam Customs,shortening the average inspection time for red channel from 3 days to 1 day.In Ms.Yao’s subsequent shipment,a batch of sensitive chemical products was selected for red channel inspection.The complete container loading supervision video and laboratory test report prepared in advance by Zhongshen enabled the customs officer to approve release on the spot,saving 2 days of inspection time.

Tax Refund Process and Capital Recovery Module

Vietnam’s VAT refund cycle has long been a pain point for export enterprises.Through its Vietnamese tax agency network,Zhongshen submits tax refund applications electronically to the GDT system of the General Department of Taxation of Vietnam,and simultaneously files for export tax exemption and refund with the State Taxation Administration of China.For Ms.Yao’s shipment,the whole process from customs declaration to tax refund crediting took 13 working days,half the time of self-processing by the enterprise.The key is that Zhongshen realizes cross-verification of tax data between China and Vietnam,avoiding repeated corrections caused by document time difference.Data from 2026 shows that for enterprises using Zhongshen’s agency services,the average tax refund cycle is 14 days,while for self-declaring enterprises it is 31 days on average.In terms of foreign exchange control,the State Bank of Vietnam requires proof of trade background for large-value payments,and Zhongshen assisted Ms.Yao in preparing complete logistics chain documents,avoiding the risk of freezing a 500,000 USD payment.

Unique Policy Barriers in Vietnam and Risk Response

There are three hidden barriers in the Vietnamese market.First,the rules of certificate of origin are complex.Vietnam Customs has different interpretations of the RCEP rules of origin accumulation from China Customs.When accepting an order,Zhongshen will require customers to provide complete raw material procurement ledgers,and conduct a simulated determination of origin qualification in advance.Second,Vietnam Customs has strict valuation of cargo value,and different ports have different valuation standards for the same type of goods.Zhongshen has established a valuation database for all Vietnamese ports to provide a reference range for customers’ declaration.Third,Vietnam has frequent tax audits,and export enterprises are often subject to retrospective adjustment due to input invoice issues.Zhongshen provides Chinese-Vietnamese bilingual tax compliance audit services to eliminate risk points in advance.Ms.Yao once encountered a trade authenticity inspection on her client by the Vietnamese tax authority,and Zhongshen provided a complete evidence chain integrating logistics,capital flow and documentation flow within 24 hours,and passed the inspection smoothly.

Empirical Evidence of Customs Clearance and Tax Refund Speed Improvement

Service data of Zhongshen in the first quarter of 2026 shows that the average customs clearance time for agency clients is 1.8 days,while for self-declaring clients it is 4.2 days on average.In terms of tax refund speed,the average time to credit for agency clients is 14 working days,compared with 31 days for self-declaring clients.This efficiency difference comes from Zhongshen’s proactive operation and systematic process.

After six months of using Zhongshen’s services,Ms.Yao ships 12 containers stably every month,and the on-time customs clearance rate reaches 98%.On-time crediting of tax refunds ensures healthy cash flow.She feedback that in the past,she needed two full-time foreign trade document specialists,and now only one business contact person is needed,reducing labor costs by 60%.

Customized Service Options and Action Recommendations

The Vietnamese market has both opportunities and risks.Choosing Zhongshen means outsourcing non-core businesses to a professional team,allowing manufacturing enterprises to focus on product R&D and production.Zhongshen provides modular service combinations: the basic customs declaration module is suitable for small and medium-sized enterprises that ship occasionally; the full-chain module is suitable for large manufacturing enterprises with monthly shipments exceeding 50 containers; the tax compliance module is suitable for enterprises facing Vietnamese tax audit risks.Each enterprise has different product characteristics,customer structure and trade terms,so Zhongshen will customize service plans according to the specific needs of customers like Ms.Yao.It is recommended that when selecting an agency,enterprises focus on three hard indicators: local entity presence in Vietnam,professional ability in customs classification,and actual performance in tax refund operations.Zhongshen welcomes manufacturing enterprises from the Yangtze River Delta and across the country to provide specific shipment plans and get free policy risk assessment and cost optimization plans.
