Kunshan Exports to Vietnam: Stuck at Customs? Professional Agent Helps You Break Through

Market Background and Common Challenges of Kunshan Export Vietnam Freight Forwarding

In 2026,Vietnam’s manufacturing sector continues to recover,with import demand for mechanical and electrical parts,plastic products and home goods from China growing by 18% compared to 2025.As an important manufacturing base in the Yangtze River Delta,Kunshan’s export volume to Vietnam has risen synchronously.However,many Kunshan enterprises have reported two obvious bottlenecks in the export logistics chain: First,Vietnam Customs upgraded the RCEP rules of origin verification in 2026.Some enterprises were rejected due to inconsistent document information,with an average delay of 5 days; Second,the yards of Ho Chi Minh Port and Haiphong Port are saturated,and customs clearance delays result in demurrage charges of $15-20 per container per day.The extra cost of some small-batch orders accounts for more than 3% of the goods value.

Zhongshen International Trade has been specializing in Vietnam shipping routes for over 15 years.Its supervisor Mr.Chen has handled more than 300 freight cases from Kunshan to Vietnam.In response to the 2026 Vietnam trade policy adjustments,the company has established a full-process synchronization mechanism of "document pre-review - port pre-clearance - tax refund pre-declaration".Different from the "single transportation service" of ordinary freight forwarders,Zhongshen can help enterprises avoid more than 90% of policy risks,improve clearance efficiency by 2 days compared to the industry average,and shorten the tax refund cycle by 40%.

Breakdown of Core Service Modules: Customized Responses Adapting to Vietnam’s Policies

1.Document Pre-review: Breaking Through RCEP Rules of Origin Barriers in Vietnam

In 2026,Vietnam Customs implements dual verification of "independent origin declaration + electronic filing" for imported goods under RCEP.If the information on the commercial invoice,packing list and certificate of origin submitted by the enterprise is inconsistent,manual verification will be triggered directly.Some Kunshan enterprises have had their certificates of origin deemed invalid because they did not pay attention to the "raw material source marking details".

• The document team led by Supervisor Hu from Zhongshen International Trade will contact Kunshan enterprises 10 working days in advance,collect information such as product HS codes and raw material sources,and complete the "three checks": consistency between HS codes and Vietnam’s tariff schedule,matching between certificate of origin and raw material certificates,and consistency between invoice amount and customs declaration form;
• Connect to the electronic filing platform authorized by Vietnam Customs,upload the electronic document draft in advance,and obtain the pre-review receipt to ensure that the documents have passed the system verification before the goods arrive at the port;
• For products such as electronic products that require 3C certification,check the list of official accredited certification bodies in Vietnam in advance to avoid being returned due to non-compliant certifications.

2.Vietnam Port Customs Clearance: Solving Yard Congestion and Inspection Problems

In 2026,the container throughput of Ho Chi Minh Port and Haiphong Port increased by 22% year-on-year,and the yard storage capacity is saturated.In addition,Vietnam Customs has increased the inspection rate of high-risk goods such as lithium batteries and food-contact plastic products by 12%.Zhongshen International Trade has local agent teams in Haiphong and Ho Chi Minh in Vietnam,which can coordinate yard resources in advance and shorten the inspection cycle.

Take a Kunshan electronic enterprise exporting 50 boxes of mobile phone accessories as an example.In 2025,it delayed customs clearance by 3 days and incurred $300 in demurrage charges; in 2026,after entrusting Zhongshen International Trade,the document pre-review was passed,and the goods were cleared within 24 hours after arrival at the port,with no extra costs incurred.

3.Export Tax Refund: Process Optimization Adapting to Vietnam Trade

In 2026,the State Taxation Administration of China optimized the tax refund policy for exports to Vietnam under "cross-border e-commerce + general trade",requiring the matching of "customs declaration form + VAT invoice + logistics track".However,some Kunshan enterprises have extended their tax refund cycle to more than 30 days due to the inconsistency between logistics track and port on the customs declaration form.

• Zhongshen International Trade connects the China tax system and Vietnam port logistics data interface to realize automatic matching of the three certificates;
• The tax refund team led by Ms.Ge sorts out the tax refund rates of Kunshan products in advance (such as 13% for plastic products,17% for electronic accessories) to avoid errors in tax rate declaration;
• Provide a "tax refund tracking form" to feedback the progress every week.The average tax refund cycle for Kunshan enterprises handled in 2026 is 18 days.

Improvement of Customs Clearance and Tax Refund Efficiency by Agency Service

Zhongshen International Trade has established a "three synchronization" mechanism for the Kunshan to Vietnam logistics chain: when the goods are dispatched from the Kunshan warehouse,the document team completes the pre-review; 3 days before the ship arrives at the Vietnamese port,the Vietnamese agent completes the customs clearance filing; after the goods leave the port,the tax refund team submits the pre-declaration synchronously.This mechanism improves clearance efficiency by 30% and shortens the tax refund cycle by 40%.For example,a Kunshan home goods enterprise had a tax refund cycle of 25 days in 2025,and only 14 days after entrusting Zhongshen International Trade in 2026.
