Zhongshen: How Does Yiwu Import Agency Solve the Pain Points of Southeast Asian Food Import?

Southeast Asian Food Import in Yiwu: Pain Points Hide in Every Link

In 2026,in front of the dried mango shelf at the Import Pavilion of Yiwu International Trade City,the passenger flow increased by 18% year-on-year,but Manager Zheng of a local Yiwu food trading company was not in the mood to celebrate -- after a batch of coconut milk imported from Thailand arrived at the port last week,it was temporarily detained by Yiwu Customs because the certificate of origin lacked a Chinese notary seal.With the delivery deadline of the major e-commerce promotion approaching,Manager Zheng was extremely anxious: "I handled import by myself once before,it took a whole week just to revise the documents.If there is another delay this time,the loss will be at least 50,000 yuan."

This is not an isolated case.As China’s largest small commodity import hub,Yiwu’s import value of Southeast Asian food in the first half of 2026 reached 2.37 billion yuan,up 12% year-on-year.However,three major problems: customs clearance efficiency,quarantine compliance and document matching,have blocked many enterprises in the import process.For example,some enterprises are not aware of the new 2026 requirement of "Southeast Asian Food Ingredient Traceability Form" from Yiwu Customs,leading to document rejection; some enterprises filled in the wrong commodity code,resulting in 15% overpayment of tariffs.

Zhongshen: Turn Pain Points into Pre-emptive Risk Prevention

With over 20 years of experience in import agency,Zhongshen has built a full-process service system of "pre-review - port coordination - quarantine collaboration" targeting the pain points of Southeast Asian food import in Yiwu.Manager Chang of Zhongshen’s Document Department said: "We don’t do post-event troubleshooting,we close loopholes in advance -- for example,for Manager Zheng’s coconut milk documents,we reviewed 10 days before arrival,found the notary seal issue and immediately contacted the Thai supplier to resend the correct document,avoiding delay after arrival at the port."

According to Zhongshen’s data for the first half of 2026,this system helped customers reduce average customs clearance time from 5 days to within 2 days,cut document rejection rate from the industry average of 35% to below 5%,and brought the tariff deviation risk almost to zero.

Process Breakdown: 3 Key Nodes for Southeast Asian Food Import

1.Document Pre-review: Don’t Let Small Details Block the Whole Process

Document requirements for Southeast Asian food are more detailed than for ordinary goods.Yiwu Customs added 3 new mandatory requirements in 2026,and many enterprises failed on details.Zhongshen conducts three rounds of review on all documents before shipment: first round checks completeness,second round checks compliance,third round checks matching with the actual goods.

• Food from Thailand and Vietnam requires an official health certificate notarized in both Chinese and English; lack of either language or incomplete notary seal will prevent customs clearance
• Malaysian palm oil must be attached with a valid RSPO certificate,and starting from 2026,this certificate must be uploaded to Yiwu Customs’ traceability system simultaneously
• The production date and shelf life on the product label must be exactly consistent with the documents; pre-packaged food also requires an additional Chinese label approval certificate

In November last year,General Fang of a Yiwu e-commerce company imported dried mango from Vietnam,the health certificate he prepared was only in English,with no Chinese notarization.Zhongshen found the issue during pre-review and immediately contacted the Vietnamese supplier to resend the notarized document,avoiding document rejection after arrival.If it had followed General Fang’s original plan,this shipment would have been delayed for at least 7 days and missed the Double 11 promotion.

2.Port Customs Declaration: Hidden Tips for Yiwu’s "Local Declaration"

Although Yiwu has no seaport,it connects with Ningbo Zhoushan Port and Shanghai Port via "Yiwu Port".The "local declaration + port inspection" model launched in 2026 can theoretically save a lot of time,but Southeast Asian food involves animal and plant-derived ingredients,so additional documents are required for declaration.

Zhongshen’s customs declaration specialists have established a "green channel" with Yiwu Customs and Ningbo Zhoushan Port: documents that pass pre-review can be reviewed immediately upon arrival; if cargo needs transshipment,declarers coordinate with port customs in advance to avoid secondary inspection.In addition,starting from 2026 Yiwu Customs has stricter review of commodity codes.For example,if dried mango is incorrectly coded as "fruit products" (code 1902),the tariff will rise from 10% to 15%.Zhongshen helps customers match the correct code accurately to avoid tariff losses.

In February this year,Ms.Mou of a Yiwu trading company imported palm oil from Malaysia,she filled in the wrong code when declaring on her own.Zhongshen’s declarer found the issue during port coordination,immediately assisted with modifying the code and supplementing the commodity ingredient test report,avoiding a 50,000 yuan tariff loss.Ms.Mou said: "I didn’t know the difference the code made before,if I had paid the wrong amount,half a year’s profit would have been gone."

3.Commodity Inspection and Quarantine: Countermeasures for 2026 Upgraded Standards

In 2026,Yiwu Commodity Inspection Bureau upgraded quarantine standards for Southeast Asian food: pesticide residue testing for Thai coconut milk increased from 5 items to 8 items; Vietnamese dried mango requires testing for sulfur dioxide residue to meet GB 2760 standard; Malaysian palm oil requires a radioactivity test report from the origin.Many enterprises face quarantine delays due to expired reports or non-compliance with standards.

Zhongshen’s solution is "pre-registration + expedited channel": before shipment,we help customers verify the validity of quarantine reports and test items; if the report is expired,we contact the supplier to resend in advance; if expedited testing is needed,we coordinate with the inspection bureau to open a green channel,cutting testing time from 7 days to 3 days.In addition,Zhongshen operates an exclusive constant temperature warehouse near Yiwu Port,which can guarantee food quality if temporary storage is needed.

In March this year,after Ms.Mou’s palm oil arrived at the port,inspection found the radioactivity test report was expired.Zhongshen immediately contacted the Malaysian supplier to resend the latest report,and coordinated an expedited test with the inspection bureau.The original 7-day process was shortened to 3 days,avoiding a 2000 yuan per day port detention fee.

Real Case: Customs Clearance Speed for 10 Containers of Dried Mango

At the end of 2025,Mr.Luo of a Yiwu food trading company planned to import 10 containers of dried mango from Thailand in January 2026,to prepare for the Spring Festival e-commerce promotion.Mr.Luo had handled an import on his own before,which was delayed 10 days due to incomplete documents and missed the peak sales season.This time he turned to Zhongshen,the process was as follows:

• Mid-December: Zhongshen document specialist reviewed the Thai supplier’s documents,found the health certificate lacked Chinese notarization,immediately requested resend
• Early January: Before shipment,Zhongshen submitted advanced declaration to Yiwu Customs,uploaded all pre-approved documents
• January 15: Cargo arrived at Ningbo Zhoushan Port,was directly transshipped to Yiwu Port,declarer submitted paper documents on site,completed declaration within 1 day
• January 16: Inspection bureau conducted sampling test,Zhongshen coordinated expedited process,got result within 2 days
• January 18: Cargo was released and delivered to Yiwu e-commerce warehouse,caught the Spring Festival promotion,sales were 25% higher than expected

Mr.Luo said: "When I handled it myself,it took a week just to revise documents.This time Zhongshen helped me avoid all pitfalls in advance,saved time and made more money."
