# Entrust Foreign Trade Company for Import Agency? Full Analysis of Thai Durian Import Process

Mr.Shen,a fresh produce trader in Shanghai,has been bothered recently: In 2026,Thailand’s durian export quota to China increased by 12% year-on-year,he wants to take the opportunity to import a batch of Monthong durian,but he still could not figure out the specific format requirements of the "Official Thai Phytosanitary Certificate" even after going through all policy documents,and he is even more worried about being stuck during customs clearance due to incomplete temperature records.Similar problems are not uncommon among fresh produce import enterprises in Shanghai: As a fresh agricultural product requiring low-temperature cold chain transportation,Thai durian has many "invisible thresholds" in the import process,a little negligence may lead to cargo detention at port,deterioration and even return shipment.

As a local company in Shanghai with more than 20 years of deep engagement in foreign trade agency,Zhongshen can just help enterprises cross these thresholds.Different from enterprises exploring on their own,Zhongshen’s import agency service intervenes in the whole process from "preliminary pre-review" to "follow-up tax refund",focusing on the characteristics of fresh agricultural products such as durian,and avoids compliance risks in advance.

## 1.Pre-import Difficulties of Thai Durian: Document Pre-review Cannot Be Done After Problems Occur

Document requirements for Thai durian import in 2026 are more detailed than previous years,especially for popular varieties such as "Monthong" and "Chani".The phytosanitary certificate issued by Thai authority must include three key pieces of information:**Official registration number of the durian plantation**,**Pre-cooling temperature curve of the shipping container**,**Exporter’s certification qualification from Thai Ministry of Agriculture**.Many enterprises are often missing one of these items,only to find they cannot declare customs when the cargo arrives at the port.

Zhongshen’s approach is: Before the client signs the contract with the Thai supplier,it will list these three requirements as a checklist for the supplier to verify,and connect with Shanghai Customs’ pre-review system to upload scanned documents in advance.Last month,Mr.Xue’s company avoided the loss of being unable to clear customs after cargo arrival because Zhongshen found in advance that the supplier’s phytosanitary certificate lacked the plantation number,and asked the other party to reissue it in time.

## 2.Port Customs Declaration: Cold Chain Temperature Is the "Lifeline"

### (1) Core customs declaration requirements for durian import

Thai durian is a fresh agricultural product included in the Catalogue of Import Quarantine Approval.In addition to conventional bill of lading,invoice and packing list,you also need to provide:**Full-course cold chain temperature monitoring record (record once every 2 hours)**,**Container fumigation certificate (for pest and disease control requirements in some Thai production areas)**.In 2026,Shanghai Customs has particularly strict review on temperature records.Once the temperature exceeds 10for 4 consecutive hours,re-quarantine will be required.

- Zhongshen arranges dedicated staff to connect with the customs declaration system 3 days before cargo arrival,and upload temperature records in advance;
- For fumigation certificates,Zhongshen cooperates with many qualified fumigation companies in Thailand,and can confirm the validity of the certificate in advance;
- Arrange dedicated staff to follow up on site during customs declaration,to avoid delay in release caused by minor document issues.

## 3.Commodity Inspection Link: Exclusive Quarantine Standards for Durian

The inspection focus of Thai durian is **pest and disease detection** and **pesticide residue detection**.2026 adds a new "ethylene content detection for durian pulp" -- because excessive ethylene will cause durian to ripen and deteriorate in advance.During inspection,3 boxes of durian will be randomly sampled,5 samples are taken from each box for testing,the whole process takes 2-3 days.

Zhongshen’s support: Communicate with the testing laboratory of Shanghai Commodity Inspection Bureau in advance to confirm the specific sampling requirements (e.g.durian must retain the fruit stem,samples need to be stored under refrigeration); at the same time arrange the warehouse to prepare a refrigerated temporary storage area in advance,to avoid sample deterioration affecting the test result.Last year,Manager Niu’s company got an invalid test result because they did not pay attention to the sample storage temperature,re-sampling delayed another 2 days,while Zhongshen’s clients can control the test time within 2 days.

## 4.Compliance Requirements and Support Methods for Each Stage of Thai Durian Import

## 5.Actual Case: Key Operations to Avoid Port Detention Loss

Last month,Mr.Bai,owner of a fruit wholesale business in Shanghai,asked Zhongshen to help import 10 containers of Thai Monthong durian.Mr.Bai imported once by himself before,because he did not conduct document pre-review in advance,he found the supplier’s phytosanitary certificate lacked the plantation number after cargo arrival.As a result,the cargo was detained at the port for 5 days,temperature record fluctuated,and finally 2 boxes of durian deteriorated.After entrusting Zhongshen this time,Zhongshen first verified all documents from the supplier,uploaded them for customs pre-review in advance.Customs declaration was completed on the same day the cargo arrived,and commodity inspection got the result in 2 days because sample storage conditions were prepared in advance.The whole process was 7 days faster than last time,and no deterioration loss occurred.

## 6.Core Value of Zhongshen’s Agency Service

For import enterprises in Shanghai,when importing fresh agricultural products such as Thai durian,time is cost and compliance is the bottom line.Zhongshen’s import agency service is not a simple "on-site customs declaration errand",but makes advance arrangements according to product characteristics -- from detailed verification in document pre-review,to temperature monitoring in port customs declaration,and to sample preparation for commodity inspection,every step is aligned with the "key nodes" of durian import.This can not only shorten the import time by more than 30%,but also avoid port detention and return shipment loss caused by compliance issues,allowing enterprises to seize the 2026 durian import dividend with more peace of mind.
