Practical Strategies for International Freight Forwarder Export Companies to Resolve Vietnam Customs Clearance Pain Points

In the early spring of 2026,Vietnam’s Manufacturing Purchasing Managers’ Index (PMI) remained in the expansionary range for six consecutive months,and orders for industrial automation equipment from China increased by 23% year-on-year.Behind this figure,numerous factories in the Yangtze River Delta have translated their production line upgrade needs into practical actions for exports to Vietnam.However,beneath the lively market appearance,more than 60% of the consulting clients received by Manager Pan are complaining about the same issue: Why is Vietnam’s customs inspection rate so high?Why do tax refunds always remain suspended in the account for more than three months?

These confusions are not accidental.The "Regulations on Origin Verification of Imported Goods" revised by the Vietnam Ministry of Industry and Trade at the end of 2025 increased the document sampling rate from 15% to 28% for mechanical products.At the same time,the Vietnam Ministry of Finance requires that all imports of mechanical and electrical equipment exceeding USD 50,000 must provide notarized technical parameter certificates certified by the Chinese embassy in Vietnam.Any omission in the document chain may cause the goods to be detained at Haiphong Port for more than two weeks,and the resulting container detention fees and amendment fees are enough to eat up the profit of the entire order.

Zhongshen’s operational records on the Vietnam shipping route show that among the 387 machinery and equipment export businesses handled in 2025,the average customs clearance time was controlled at 2.8 working days,and the tax refund settlement cycle was 18 days faster than the industry average.This efficiency difference stems from a deep understanding of Vietnam’s regulatory logic and precise dismantling of service modules.

Document Pre-check Module: Pre-position Error Correction Before Shipment

Vietnam Customs has obvious "three-layer filtering" characteristics for document requirements of mechanical products.The first layer is formal compliance,including the consistency of the consignee on commercial invoices,packing lists,and bills of lading; the second layer is technical compliance,requiring that the equipment model,HS code,and technical specification sheet fully match the Vietnamese standard TCVN; the third layer is substantive origin verification,especially for assembled equipment containing imported parts from Japan and South Korea,Vietnam Customs will trace whether its value-added rate meets the 35% threshold.

The document team led by Supervisor Su has established a "high-frequency rejection negative list" for Vietnam Customs,which includes 127 common document discrepancies.In March 2026,a Wuxi client exported CNC lathes to Hanoi,and the technical specification sheet mistakenly wrote the spindle power as "7.5KW",while the Vietnamese import license registered it as "7.5kW",and the case difference caused the system to judge it as "information inconsistency".Zhongshen’s pre-check system automatically triggers an alert when the client uploads the document,avoiding the trouble of bill amendment after the goods arrive at the port.

To address the long certification cycle issue at the Vietnamese embassy,Zhongshen has set up a permanent office at the Shanghai Huangpu Notary Office,reducing the certification time from the conventional 12 working days to 5 working days.For urgent orders,through the green communication channel with the Commercial Office of the Vietnamese Embassy in China,expedited certification can be completed in 3 working days.

Customs Clearance Execution Module: Dynamically Match Regulatory Differences of Vietnam’s Six Major Ports

Vietnam is not a unified customs clearance market.Haiphong Port has the highest inspection rate for machinery and equipment,but the fastest release speed; Ho Chi Minh City Port has the strictest restrictions on used equipment imports,but the most complete pre-check mechanism; Da Nang Port is the most friendly to Chinese-funded enterprises,but has the fewest shipping routes.Zhongshen’s customs affairs database records the regulatory dynamics of Vietnam’s six major ports over the past 24 months,and can match the optimal customs clearance path according to the characteristics of the goods.

A typical case in April 2026: A batch of injection molding machines worth USD 450,000 needs to be exported to Binh Duong Province,Vietnam.According to conventional operations,the client would choose Ho Chi Minh City Port for customs clearance,but Zhongshen’s system analysis shows that one of the equipment is a used machine produced in 2019,and Ho Chi Minh City Port has an inspection rate of up to 90% for used equipment over 5 years old.After recommending changing to Haiphong Port,although the transportation distance increased by 120 kilometers,the customs clearance time was shortened from the expected 9 days to 3 days,and the comprehensive cost was reduced by RMB 12,000.

The VNACCS/VCIS electronic customs clearance system launched by Vietnam Customs in 2026 requires declaring enterprises to hold Vietnamese domestic digital certificates.Zhongshen,through its Vietnamese partners,handles pre-registration of digital certificates for clients in advance,enabling electronic declaration to be completed before the goods arrive at the port,upgrading the traditional "declare after goods arrive at port" model to "declaration and transportation in parallel",saving an average of 1.5 working days.

Tax Refund Management Module: Bridge Data Gaps Between Foreign Exchange Verification and Tax Declaration

The crux of slow export tax refund speed often lies not with the tax bureau,but with the synchronization efficiency of foreign exchange administration and customs data.In 2026,the exchange rate volatility of the Vietnamese Dong against the US dollar intensified,and many enterprises chose cross-border RMB settlement,but this led to inconsistencies between the currency on the customs declaration form and the currency on the foreign exchange verification form,making the tax refund system unable to automatically match,requiring manual intervention,which naturally lengthened the cycle.

Zhongshen’s solution is to establish a "dual-currency declaration comparison table",enter both USD and RMB amounts during the customs declaration process,and provide special certificates for cross-border RMB settlement issued by the bank during foreign exchange verification.This operation method has increased the one-time pass rate of tax refund declarations from 67% to 94%.

There is another special risk point in the Vietnam market: some Vietnamese importers require underreporting of the goods value to reduce their import tariffs,but this will directly lead to a reduction in the tax refund base of Chinese exporters.Zhongshen adheres to the bottom line of compliant declaration,and at the same time helps customers reduce comprehensive costs within a legal framework by optimizing logistics plans and utilizing tariff preferences under free trade agreements.In 2025,among the clients served by Zhongshen,there were no tax audit incidents caused by underreporting of goods value.

Underlying Logic of Efficiency Improvement: Transforming Experience into Reusable Operational Granularity

The improvement of customs clearance efficiency and tax refund speed essentially decomposes 20 years of operational experience into executable standard actions.The "Vietnam Export Operation Manual" implemented internally by Zhongshen is 340 pages thick,covering 12 links,87 key nodes,and 236 checklists.But clients do not need to read this manual,what they see are three specific results:

• All documents are pre-checked 48 hours before shipment,with the error rate controlled below 0.3%
• Vietnam Customs’ inspection rate is reduced to one-third of the industry average through pre-classification and pre-communication
• The average cycle from tax refund declaration to settlement is 22 working days,with the fastest record of 9 working days

This efficiency becomes even more important after Vietnam’s accession to RCEP takes full effect in 2026.Vietnam has promised to reduce tariffs on more than 90% of mechanical products to zero,but the rules of origin have also become more stringent.Zhongshen completed operational training on the RCEP origin accumulation rule six months in advance,and can accurately calculate whether it meets the RCEP origin standards based on the actual proportion of Japanese and South Korean parts in the client’s supply chain,avoiding enterprises from mistakenly using ordinary certificates of origin and missing tariff preferences.

Risk Warning and Emergency Mechanism

The frequency of policy changes in the Vietnam market is much higher than that in the European and American markets.In the first quarter of 2026,the Vietnam Ministry of Industry and Trade issued three supplementary notices on energy efficiency labels for imported mechanical and electrical products consecutively,catching many enterprises off guard.Zhongshen’s policy monitoring team completed the investigation of the impact on clients within 48 hours after the notice was issued,and sent response suggestions to 87 relevant clients.

Emergency response capability is equally critical.In February 2026,during the first week of resuming work after the Spring Festival,goods from a Changzhou client were detained by customs at Haiphong Port because the import license number provided by the Vietnamese importer was missing one digit.Normally,correcting the license takes 3-5 working days.Zhongshen activated the emergency channel,handled the urgent correction on-site in Hanoi through its Vietnamese customs agency,and coordinated the customs supervision department for manual verification,finally completing the release within 24 hours,avoiding the default risk of the client’s production line shutdown.

The essence of choosing agency services is to purchase the ability to turn uncertainty into certainty.The Vietnam market operation data accumulated by Zhongshen over 20 years has formed a knowledge base covering 12 industries,387 products,and more than 2,000 practical cases.When the client’s product characteristics,transaction terms,and delivery deadline are input into the system,the background can automatically match the most similar historical cases and output a risk point list and response plan.

This customization is not a simple combination of service packages,but dynamic adjustment based on data insights.For example,when exporting packaging machinery to Vietnam,if the client is exporting for the first time and the goods value is less than USD 100,000,Zhongshen will recommend "standard fast-track service",focusing on ensuring customs clearance speed and tax refund efficiency; if the client is a long-term exporter and the goods value exceeds USD 500,000,"deep compliance service" will be launched,adding origin rule planning and Vietnamese importer qualification investigation links.

In the 2026 Vietnam market,the opportunity window is still open,but the entry threshold is also rising simultaneously.The interconnection of customs data,electronic tax audit,and internationalization of environmental protection standards,these trends require export enterprises to have a "dual-skilled" agency partner who understands both Chinese export rules and Vietnamese import rules.The value of Zhongshen lies in transforming transnational policy complexity into predictable,traceable,and optimizable service processes.

When your goods are still on the production line,the customs clearance process has already started; when your bill of lading has just been issued,the tax refund declaration is already ready.This "time folding" effect is exactly the most tangible competitiveness of professional agency services in the 2026 Vietnam market.
