Zhongshen Offers Premium Import Sea Freight Agency & Southeast Asian Fruit Customs Clearance Solutions

1.Background and Common Pain Points of Southeast Asian Durian Import

In 2026,the import volume of tropical fruits from Southeast Asia at Shanghai Port exceeded 320,000 tons,with Thai durian accounting for over 40% of the total.Many importers in Shanghai reported three common pain points in durian import: first,the requirements for Thailand’s latest quarantine certificates are updated frequently,and document discrepancies easily lead to application rejection; second,the quarantine sampling rate for fresh fruits at Shanghai Port has been increased to 8%,and the complicated procedure easily causes delays; third,poor cold chain connectivity makes it difficult for goods to be put into storage in time after arrival,resulting in container detention fees and cargo damage.These pain points are exactly the core links that import sea freight agencies need to solve accurately.

2.Core Role of Zhongshen in Durian Import

Zhongshen has been engaged in foreign trade agency services for over 20 years.As a local agency in Shanghai,we are familiar with the latest policies and operating procedures of Shanghai Port.In response to the import demand for fresh fruits such as durian,we provide full-process services from document pre-audit to final delivery,helping enterprises control risks in advance.For example,in 2025,a Shanghai importer failed to notice the new format of Thailand’s quarantine certificate,resulting in the return of one container and a loss of over 50,000 yuan.In contrast,the document audit pass rate of clients represented by Zhongshen reached 99.5% in the past year.

3.Process Breakdown and Compliance Control of Durian Import Sea Freight Agency

1.Document Pre-audit: The First Check for Thai Durian Import

Durian import requires 3 more types of documents than ordinary goods.In 2026,Thailand updated the requirements for electronic signatures on phytosanitary certificates,and many importers had their applications rejected because they did not update the document format in time.Director Ma of Zhongshen’s document team will audit all materials provided by clients 3 working days in advance,focusing on checking the following core documents:

• Phytosanitary certificate issued by Thai authorities (must include electronic signature and the "cold treatment time" field)
• Importer consignee registration number (must be valid and within the validity period in Shanghai Customs system)
• Cold chain transportation temperature record (the temperature inside the container shall not exceed 4℃ throughout the whole journey,with a shipping company certificate attached)
• Commercial invoice and packing list (must be completely consistent with the cargo description and quantity on the bill of lading)

Last year,a Shanghai importer was required to supplement materials by Shanghai Customs because the quarantine certificate provided by the Thai supplier lacked the "cold treatment time" field.After Director Ma discovered this problem in advance,he guided the client to contact the Thai agent to supplement the certificate,avoiding the risk of cargo detention at the port for more than 48 hours.According to the cold chain storage fee standard of Shanghai Port,this alone saved nearly 8,000 yuan.

2.Port Customs Declaration: Accurately Matching Shanghai Customs Declaration Elements

In 2026,Shanghai Customs added "origin plantation number" to the declaration elements for durian import.Omission or incorrect filling will lead to automatic rejection by the customs declaration system.Manager Liao of Zhongshen’s customs declaration team is familiar with the latest declaration requirements,and will assist clients in sorting out the element list in advance.The following is the risk comparison of key declaration elements:

"In March this year,a client imported 12 containers of durian,and the packaging material of 2 boxes was declared incorrectly.Without Manager Liao’s advance check,all goods might have been inspected by customs,resulting in an increase of over 20,000 yuan in cold chain costs," Director Ma added.

3.Commodity Inspection and Quarantine: Key Requirements for Fruit Quarantine at Shanghai Port

Durian is a key regulated variety in the List of Entry Plant Quarantine Pests.In 2026,Shanghai Port added the "fruit fly larva detection" item to its quarantine,and the sampling rate was increased from 5% to 8%.Ms.Ou,Zhongshen’s quarantine liaison,will communicate with Shanghai Entry-Exit Inspection and Quarantine Bureau in advance and prepare the following materials:

• Submit quarantine declaration 24 hours before the goods arrive at the port (electronic documents must be uploaded)
• Provide the cold treatment temperature curve of each batch of goods (full record from loading in Thailand to arrival at Shanghai Port)
• Cooperate with quarantine personnel for sampling (usually 3 boxes are taken from the middle of the container,and 5 durian samples are taken from each box)

"Last year,when an enterprise imported durian,it failed to submit the cold treatment curve in advance,and quarantine personnel required re-inspection,resulting in the cargo being detained at the port for 5 days and cold chain storage fees of 12,000 yuan.Ms.Ou later assisted the enterprise in sorting out the temperature records of the past 3 months,and the import passed the quarantine smoothly this year,with the detention time shortened to less than 1 day."

4.Warehousing and Distribution: Connection Guarantee of Shanghai Cold Chain Logistics

After import,durian needs to be stored in the cold chain supervision warehouse designated by Shanghai Customs.In 2026,the utilization rate of such warehouses in Shanghai exceeded 85%.If no advance reservation is made,the goods may not be put into storage in time.Mr.Bao of Zhongshen’s logistics team has signed priority reservation agreements with 3 designated cold chain warehouses in Shanghai Pudong and Yangshan Port,which can lock the storage space in advance:

"We have agreed with the warehouses that the storage space can be confirmed 48 hours before the client’s goods arrive at the port,avoiding container detention fees caused by lack of storage space.Last year,a client spent 8,000 yuan on container detention fees because they did not reserve a warehouse,while the average container detention time of our represented clients is no more than 12 hours," Mr.Bao gave an example.

4.Actual Case: Agency Helps Enterprises Avoid 3 Core Risks

In October 2025,a food trading company in Shanghai planned to import 20 containers of Thai durian.Previously,the company had a container returned due to document discrepancies,with a loss of over 50,000 yuan.After contacting Zhongshen,our team did the following work:

• Audit documents in advance: found that the phytosanitary certificate provided by the Thai supplier lacked the "exporter registration number",and guided the client to supplement it,which passed the pre-audit smoothly
• Check declaration elements before customs declaration: confirm that the origin plantation numbers of all containers are consistent with the customs system to avoid application rejection
• Quarantine liaison: submit the cold treatment curve in advance,cooperate with sampling inspection,and complete quarantine release within 3 days

"In the end,this batch of goods only took 5 days from arrival at the port to delivery to the client’s warehouse,which was 40% shorter than the company’s previous import time.No container detention fee or additional storage fee was incurred,saving more than 30,000 yuan in costs," Director Ma said.

5.Core Value of Zhongshen’s Agency Services

For importers in Shanghai,choosing a high-quality import sea freight agency can not only improve efficiency,but also avoid compliance risks:

• Efficiency improvement: The average customs clearance time is shortened from 7 days to 3-4 days,and cold chain costs are reduced by more than 20%
• Risk avoidance: The document audit pass rate reaches 99.5%,and the quarantine return rate is less than 0.1% (the industry average is 0.5%)
• Cost control: Lock cold chain storage space and transportation prices in advance to avoid additional expenses caused by market fluctuations

"As a local agency in Shanghai,Zhongshen is familiar with every process detail of Shanghai Port.For special goods such as Southeast Asian fruits,we can accurately match the latest policies and operation requirements to help enterprises complete import smoothly," Manager Liao concluded.
