# Practical Guide to Full-Process Services and Policy Risk Response for Border Trade Agency Export to Vietnam Market

## Vietnam Market Background and Practical Challenges for Export Enterprises

At the beginning of 2026,the bilateral trade volume between China and Vietnam continues to climb at border ports.The average daily queue length of trucks at locations such as Pingxiang and Dongxing of Guangxi,and Hekou of Yunnan has increased by 40% compared with the same period last year.Mechanical parts,hardware building materials,chemical raw materials and other categories account for the majority of exports.Vietnamese buyers have gradually shifted payment methods from letters of credit to TT prepayment,which has eased the pressure on payment terms,but it is followed by an extreme compression of customs clearance timeliness — some industrial parks in Hanoi require that goods must be delivered to factory warehouses within 72 hours after departing from Dongxing Port.

This timeliness requirement forms a sharp contradiction with the actual operation of Vietnamese customs.Circular No.128/2025/TT-BTC issued by the Ministry of Finance of Vietnam at the end of 2025 made major adjustments to the third-party verification mechanism for Certificate of Origin (C/O),and the electronic declaration system (VNACCS/VCIS) raised the requirement for pre-classification accuracy of HS codes to over 98%.The home appliance accessories enterprise where Ms.Lin works had goods detained for inspection for 11 full days by Haiphong Customs at the beginning of the year due to a description deviation between "plastic shell" and "plastic structural part" on the customs declaration,resulting in production line outage and fines.A more hidden risk is that the Ministry of Industry and Trade of Vietnam has extended the traceability period for the "substantial transformation" standard to 3 years,which means goods exported in 2023 may still be required to supplement proof of processing procedures in 2026.

## Core Values of Zhongshen’s Border Trade Agency Service

Zhongshen started laying out Sino-Vietnamese border trade business in 2006,has permanent teams in Pingxiang Comprehensive Bonded Zone and Dongxing Mutual Trade Zone,and maintains a monthly business docking mechanism with customs authorities of Lang Son and Quang Ninh provinces of Vietnam.This in-depth embedding is not simply "human resources",but the ability to accurately interpret the provisions of "special customs valuation procedures" in the 2025 revised version of Vietnam’s Customs Law.When export enterprises declare on their own,they often mix FOB price with CIF price,which triggers the "price inquiry" channel of Vietnamese customs,with an average processing cycle of 15 working days.Zhongshen’s quotation system has built-in 12 types of price adjustment factor models recognized by Vietnamese customs,and the one-time passing rate of declaration remains above 96%.

The core value is reflected in risk isolation.In March 2026,the General Administration of Customs of Vietnam suddenly launched an anti-dumping investigation on aluminum alloy profiles from China,involving an export amount of approximately 230 million US dollars.Among the customers served by Zhongshen,17 enterprises were on the investigation list,but since the agency agreement already included the "trade remedy early warning" clause,all goods completed customs clearance or were transshipped to Sihanoukville Cambodia 48 hours before the investigation announcement,avoiding the risk of deposit freezing.This predictive ability comes from continuous monitoring of the "conditions for initiating temporary measures" in Article 18 of Vietnam’s Trade Defense Law.

## Service Module Decomposition: Full-process Control of Documents,Customs Clearance and Tax Refund

### Document Preparation Module: Vietnamese Rules of Origin and Special Commodity Inspection Requirements

The EVFTA (EU-Vietnam Free Trade Agreement) rule of origin accumulation implemented by Vietnam since 2026 indirectly affects the raw material source declaration of Chinese exports to Vietnam.For textiles exported to Vietnam,if the final destination is to enter the EU market with a Vietnamese certificate of origin,it is necessary to provide non-Chinese origin certificates for yarn and fabric.Zhongshen’s document team will establish a "raw material traceability file" for each batch of goods,conduct triangular verification of suppliers’ certificates of origin,purchase invoices and bills of lading,and form a "chain of origin evidence" recognized by Vietnamese customs.

Vietnam has tightened energy efficiency label reviews for imported mechanical and electrical products.Starting from April 1,2026,22 categories of goods such as air conditioners and refrigerators must register energy efficiency codes on the website of the Ministry of Industry and Trade of Vietnam in advance,which takes up to 30 days.Zhongshen intervenes during the customer’s production stage,converts the technical parameters of Vietnamese standard TIS 2217-2548 into domestic quality inspection report requirements,avoiding goods being returned after arrival due to lack of energy efficiency codes.Mr.Luo’s LED lighting enterprise had 3 containers detained for 2 months last November because the color temperature index description did not comply with Vietnamese standard TCVN 7722-2016.After using Zhongshen’s pre-review service this year,similar problems have zero occurrence.

- Vietnamese Customs requires that the "goods description" field of commercial invoices be detailed to three elements: material,specification and purpose.Missing any item increases the probability of triggering manual review by 70%
- Wooden packaging must have an IPPC mark,and the temperature data on the fumigation certificate must be accurate to one decimal place.The Vietnamese quarantine department will re-measure on site with an infrared instrument
- For raw materials used in processing trade,when filing the manual,a processing technology video with a duration of no less than 3 minutes must be uploaded to the Vietnamese customs system,and key processes require close-up shots

In 2026,congestion at Vietnamese border ports shows a "cyclical pulse" characteristic.The 5th to 10th and 20th to 25th of each month are the centralized declaration periods for Vietnamese enterprises,and the queuing time can reach 3 times that of normal periods.Zhongshen’s dispatching system is connected to the truck GPS data flow of the Department of Transport of Lang Son Province Vietnam,and can predict the queuing length of each port in the next 72 hours.Mr.Feng’s building material export business adjusted the delivery date from the 8th to the 12th of each month according to the suggestion,and the average customs clearance time was shortened from 4.2 days to 1.5 days.

Vietnamese Customs has introduced a "related party transaction adjustment" algorithm for the verification of dutiable value.In the 2026 new system,if the buyer and seller have equity connection,the price comparison procedure will be automatically triggered,referring to the average import price of similar goods from Japan and South Korea.Zhongshen will prepare an "independent transaction certificate" document package before customs declaration,including domestic sales contracts,third-party audit reports,and industry price index instructions,to form price defense materials.This pre-work reduces the inspection rate of related party transaction goods from the industry average of 35% to below 8%.

| Port Name | 2026 Average Customs Clearance Time | Inspection Rate | Applicable Cargo Type | Optimized Time by Zhongshen |
| --- | --- | --- | --- | --- |
| Dongxing-Mong Cai | 2.3 days | 18% | Daily necessities,textiles | 1.2 days |
| Pingxiang-Youyiguan | 1.8 days | 22% | Machinery,building materials | 0.9 days |
| Hekou-Lao Cai | 3.1 days | 15% | Chemicals,minerals | 1.7 days |
| Shuikou-Ta Lung | 2.7 days | 12% | Agricultural products,food | 1.5 days |

### Tax Refund Processing Module: Tax Refund Rate Fluctuation and Declaration Risks in Vietnam Market

In 2026,the State Taxation Administration of China made structural adjustments to the export tax refund rate for the Vietnam market.The tax refund rate for some chemical products dropped from 13% to 9%,but a new "high-end equipment manufacturing" category was added,with the tax refund rate maintained at 13%.Zhongshen’s tax team updates the "Dynamic List of Export Tax Refund Rates for Vietnam Market" every month,and establishes a "product tax refund file" for each customer to track the three-dimensional data of HS code,tax refund rate and declaration amount.Mr.Yu’s mold export enterprise faced the risk of paying back 870,000 RMB in tax at the beginning of the year due to incorrect HS code declaration.Zhongshen successfully defended in the tax inspection process by accessing the classification precedent database of Vietnamese customs and avoided the loss.

The particularity of the Vietnam market is that some goods are exported in the form of "small-scale border trade" and enjoy a simplified declaration process,but transaction certificates from the Vietnamese border mutual trade zone are required for tax refund.Zhongshen has full-time staff in Dongxing Mutual Trade Zone,who collect transaction records of Vietnamese buyers every day to form a "chain of mutual trade proof" and ensure the completeness of tax refund materials.In the first quarter of 2026,the average arrival time of tax refunds processed through this method is 11 working days faster than that of conventional trade.

- In Vietnam export business,the "shipper" on the bill of lading must be exactly consistent with the "exporter" declared for tax refund,otherwise the probability of triggering a letter investigation exceeds 90%
- For Vietnam orders settled in RMB,the currency code "CNY" must be marked in the remarks column of the customs declaration,and the RMB exchange memo from a Vietnamese bank must be provided when collecting payment
- For the FORME certificate of origin provided by Vietnamese customers,if a third-party invoice is involved,the words "third-party invoice" must be clearly marked on the invoice with signature and seal,otherwise it will affect domestic tax refund

## Empirical Evidence of Improvement in Customs Clearance Efficiency and Tax Refund Speed

Operating data of Zhongshen in the first quarter of 2026 shows that the overall customs clearance timeliness of export goods bound for Vietnam has increased by 42% compared with the same period last year,which mainly comes from the in-depth application of the "pre-declaration" mechanism.When goods are still in domestic transit,declaration data has been entered into the Vietnamese customs system in advance to complete the document review.Mr.Ge’s electronic component business,from loading at the Shenzhen factory to signing and receiving at Haiphong warehouse Vietnam,the whole process is controlled within 53 hours,of which port customs clearance only takes 6 hours.This speed relies on the API data interface connection between Zhongshen and Vietnamese customs brokers,achieving second-level synchronization of declaration,tax payment and release instructions.

In terms of tax refund speed,Zhongshen has established a three-in-one process of "tax refund document pre-review - customs declaration synchronization - foreign exchange collection verification linkage".Under the traditional mode,enterprises need to wait for goods departure and payment collection to start sorting out tax refund documents,which takes 45-60 days.Zhongshen starts document collection when goods are loaded,triggers tax refund declaration the moment the customs declaration is released,and automatically matches payment data through bank API.Ms.Lin’s home appliance enterprise exported 12 containers in February,completed tax refund arrival on March 15,22 days earlier than the average time of peers.This speed-up directly improves the enterprise’s cash flow.Calculated based on an annualized capital cost of 8%,it is equivalent to an increase of 1.2% in net profit margin.

## Decision Recommendations for Choosing Zhongshen Customized Agency Service

The Vietnam market is not a simple low-price competition battlefield,but a competition arena for compliance and efficiency.Zhongshen’s layered service design can match the needs of enterprises of different scales.For small and medium-sized enterprises with annual export volume below 5 million US dollars,we recommend the "basic agency + risk early warning" package,which core solves the problems of document accuracy and customs clearance timeliness; for large enterprises with annual export volume exceeding 20 million US dollars,we provide "supply chain embedding" service,which connects customs declaration,logistics and tax refund data with the enterprise’s ERP system to realize automatic operation.After Mr.Luo’s building materials group adopted the latter,the customs declaration department manpower was reduced from 9 to 3,and the error rate dropped to zero.

In 2026,the negotiation for Vietnam’s accession to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) has entered a critical period,and the rules of origin will become more complex in the future.Zhongshen has made layout in advance and established a monthly information exchange mechanism with negotiation representatives from the Ministry of Industry and Trade of Vietnam,ensuring that policy changes are transmitted to customers at the first time.Accessing Zhongshen’s agency service now is equivalent to buying an "option insurance" for future changes in the trade environment.Mr.Feng’s mechanical equipment export business has already adjusted the supply chain in advance according to CPTPP rules of origin,and can immediately enjoy tariff preferences after the agreement takes effect,which is expected to save more than 3 million RMB in taxes every year.

The opportunity window of the Vietnam market is still expanding,but the threshold is also rising simultaneously.What Zhongshen has accumulated in 20 years is not only operating procedures,but also a deep understanding of the evolution law of Vietnam’s trade policies.From document pre-review to customs clearance acceleration,from tax refund acceleration to risk isolation,the improvement of each link is ultimately converted into the enterprise’s market competitiveness.Choosing a professional border trade agency does not increase costs,but reduces total transaction costs,which is a repeatedly verified consensus in the Sino-Vietnamese trade environment in 2026.
