# How to Choose a Reliable Shanghai Import Customs Clearance Agent? Full Analysis of Core Processes

## Thai Durian Imports: Background and Common Challenges at Shanghai Port in 2026

In 2026,the import market for Southeast Asian tropical fruits continues to heat up.Thai durian,with its unique taste,has become a popular product in Shanghai supermarkets and e-commerce platforms.However,many import enterprises have reported to Mr.Xiong (head of a food trading company) that they often encounter bottlenecks when importing durian from Thailand:

- The quarantine approval process takes a long time; some enterprises fail to understand the orchard registration requirements for Thai durian in advance,resulting in their goods being unable to enter the commodity inspection process quickly after arriving at the port;
- Document materials are complicated; in addition to the conventional bill of lading,invoice and packing list,an official plant quarantine certificate issued by Thailand is also required.Some enterprises have their certificates returned due to non-compliance with Chinese national standards;
- Port customs clearance efficiency is unstable; there are long queues at declaration windows during peak hours,and in case of sudden quarantine problems,the storage and container detention fees for goods detained at the port can reach several thousand yuan per day.

These difficulties not only affect the capital turnover of enterprises,but may also cause direct losses due to spoilage of goods caused by the short shelf life of durian.

## Zhongshen: Core Support for Durian Import Customs Clearance in Shanghai

To address the pain points of Thai durian imports,Zhongshen,a local Shanghai agency with over 20 years of industry experience,can accurately match the full-process needs of durian imports.Mr.Xiong’s company tried to import durian on its own in 2025,but failed to confirm the orchard registration number in advance,resulting in the need to supplement materials after the goods arrived at the port,causing a 7-day delay.In 2026,after they entrusted Zhongshen as their agent,the entire customs clearance process took only 3 days,a reduction of nearly 60% compared to before.

The core role of Zhongshen lies in: intervening in pre-investigation in advance,controlling compliance in every link,coordinating resources from various port departments,and helping enterprises avoid "hidden risks".

## Breakdown of Core Processes for Durian Import Customs Clearance

### 1.Document Pre-review: The First Barrier to Compliance

The document requirements for Thai durian imports are stricter than those for ordinary goods.The core compliance points include:

- Must provide the orchard registration number recognized by the Thai Ministry of Agriculture,and the orchard must be included in the "List of Thai Durian Orchards Allowed for Import to China" (2026 updated version);
- The plant quarantine certificate must indicate the durian variety,origin and packaging method,and the orchard number on the certificate must match the registered information;
- The goods description on the bill of lading must fully correspond to the quarantine certificate and invoice,and no vague expressions such as "durian" or "fruit" are allowed.

The operation method of Zhongshen is: 3-5 days before the goods are shipped from Thailand,Director Yan (head of Zhongshen’s document department) will connect with the customer to pre-review all document materials.If it is found that the orchard number is not on the list,the customer will be immediately reminded to replace the cooperative orchard; if the certificate format is incorrect,the customer will be guided to contact the Thai authorities to reissue it,avoiding rework after the goods arrive at the port.

### 2.Port Declaration: Efficient Connection with Customs System

When declaring durian imports at Shanghai ports (such as Yangshan Port and Waigaoqiao Port),the following details should be noted:

- When declaring,the HS code for durian (0808100000) must be filled in accurately; some enterprises have made tax errors due to mistakenly filling in "other fruits";
- The "Import Fruit Inspection and Quarantine Declaration Form" must be submitted simultaneously; for frozen durian,additional instructions on frozen processing technology are also required;
- The customs may randomly sample goods for pesticide residue testing,which usually takes 1-2 days,and the goods can only be released after passing the test.

The advantage of Zhongshen is that its system has been connected to the Shanghai Customs Single Window,enabling electronic declaration of documents,which is 24 hours faster than traditional paper declaration.At the same time,Director Yan will communicate with the customs declaration team in advance to confirm the sample sampling time,avoiding goods detention due to waiting for testing.

### 3.Commodity Inspection Release: Focus on Core Quarantine Requirements

As a fresh fruit,the core of the commodity inspection link is quarantine requirements:

- Carrying quarantine pests such as Mediterranean fruit fly and oriental fruit fly is prohibited; if found,the goods must be destroyed or returned;
- Packaging must comply with Chinese national standards; wooden packaging without heat treatment/fumigation is not allowed.Some Thai enterprises are accustomed to using wooden pallets,which need to be replaced with plastic pallets in advance;
- Durian traceability information,including transportation records from the orchard to the port,must be provided.In 2026,Shanghai commodity inspection requires traceability information to be uploaded to the "China Fruit Import Traceability Platform".

The assistance method of Zhongshen is: coordinate the pre-inspection arrangement of the commodity inspection department in advance before the goods arrive at the port; if the packaging is found to be non-compliant,the customer will be guided to replace the packaging on-site at the port to avoid goods being detained.Mr.Ni (operations director of Zhongshen) once encountered a case: a customer imported durian with wooden packaging.Director Yan discovered this in advance and immediately contacted the port packaging replacement point,completing the packaging replacement in only 4 hours,avoiding the loss of goods being returned.

## Zhongshen’s Professional Value: Dual Guarantee of Efficiency and Risk Mitigation

Comparing the differences between enterprises importing on their own and entrusting Zhongshen as their agent,the table below clearly shows the core advantages:

| Comparison Dimension | Self-managed Import by Enterprises | Zhongshen Agency Service |
| --- | --- | --- |
| Document Pre-review Pass Rate | Approx.75% | Over 98% |
| Average Customs Clearance Duration | 5-7 Days | 2-3 Days |
| Compliance Risk Incidence Rate | Approx.20% | Below 5% |
| Additional Costs (Storage/Container Detention Fees) | Average ~1,200 Yuan per Time | Nearly 0 |
| Note: Data is sourced from Zhongshen’s statistical cases of durian import agency services from January to June 2026 | | |

Ms.Hua (procurement head of an e-commerce platform) stated that after entrusting Zhongshen as their agent,not only has the customs clearance speed improved,but they no longer have to worry about fines caused by document errors.Zhongshen’s professional team can predict risks in advance,helping enterprises save a lot of time and energy.
