Full Process of Import Trade Agency Customs Declaration, Compliant and Efficient Clearance

1.Background and Common Difficulties of Thai Durian Import

In 2026,the demand for Southeast Asian tropical fruits in the Shanghai market increased by 32% compared to last year,among which Thai durian has become a popular import category due to its unique taste.However,many traders found in actual operations that importing durian from Thailand requires dealing with complex policy requirements - the newly revised Measures for the Quarantine Management of Imported Fruits in 2025 added clauses such as variety traceability and radioactive testing,coupled with the strict requirements of Shanghai Yangshan Customs for electronic document connection verification,a slight mistake will lead to cargo detention at the port,resulting in additional storage and detention charges.

• Documents must include the official electronic signature plant quarantine certificate issued by Thailand,and some enterprises have been rejected due to non-compliant certification institutions
• Durian must meet China’s pesticide residue limits (increased by 10% compared to 2024),and those who fail the sampling test will face return shipments
• Commodity code (HS code 0808100000) must match the variety certificate,and incorrect code will lead to tariff deviation

2.Core Role of Zhongshen Import Agency

As an agency company deeply rooted in the foreign trade industry in Shanghai for 20 years,Zhongshen provides full-process services from document pre-review to port release according to the characteristics of Thai durian import.Its core roles are: avoid policy risks in advance,accurately match compliance requirements,coordinate port and commodity inspection resources,help enterprises reduce the customs clearance cycle from the industry average of 7-10 days to 3-5 days,and reduce detention costs by more than 90%.

3.Process Breakdown and Compliance Handling of Import Agency Customs Declaration

1.Document Pre-review: Lock Compliance Risks in Advance

The document requirements for Thai durian import are significantly different from ordinary goods,and three types of materials need to be key reviewed:

• Plant quarantine certificate issued by the Ministry of Agriculture of Thailand (needs to be electronically connected with the General Administration of Customs of China,paper signatures are prohibited in 2026)
• Certificate of origin certified by the Thai Chamber of Commerce (needs to indicate the picking date of durian,which shall not exceed 30 days)
• Variety certificate (varieties such as Monthong and Musang King need to provide official Thai traceability documents separately)

In March 2026,a trader planned to import 12 containers of durian,and was required to re-sign by Yangshan Customs because the certificate of origin was not stamped with the electronic seal of the Thai Chamber of Commerce.Ms.Yu from Zhongshen immediately contacted the Thai cooperative institution,completed the re-sign and synchronized the electronic data within 24 hours,avoiding the risk of 7-day cargo detention (detention fee of about 8,000 yuan).

2.Port Customs Declaration: Accurately Match Codes and Taxation

The HS code of Thai durian is 0800000,but in 2026,durian from some production areas (such as Chanthaburi Province) need to provide "low pesticide residue certification" due to adjustments in planting technology.Zhongshen’s customs declaration team will check the code and additional materials in advance to avoid overpayment of tariffs caused by incorrect codes (the maximum deviation reaches 15%).

At the same time,port customs declaration adopts the dual-track system of "electronic declaration + on-site verification".Zhongshen’s system can automatically match the latest data of the General Administration of Customs.In the first half of 2026,the agency declaration accuracy rate reached 99.2%,much higher than the industry average of 92%.

3.Commodity Inspection Link: Implement Quarantine and Testing Requirements

The quarantine requirements of China Customs for imported durian include:

• Entry at designated ports (Shanghai Yangshan Customs is the only port allowed for durian import)
• Radioactive testing (new requirements for southern Thai production areas,need to provide soil background value report)
• Sampling testing (5 samples are taken from each container,and the number of pesticide residue items has increased from 12 to 18)

Zhongshen has established an appointment testing mechanism with Shanghai Entry-Exit Inspection and Quarantine Bureau,which can reduce the testing cycle from 5-7 days to 2-3 days.In May 2026,the radioactive testing data of durian imported by an enterprise was delayed,and Ms.Yu coordinated the testing institution to process urgently,obtained the results within 48 hours,and the goods were released smoothly.

5.Case Sharing: Solving Quarantine Problems of Durian Import

In April 2026,a food trading company in Shanghai planned to import 20 containers of Thai Monthong durian.Due to not understanding the newly revised quarantine requirements in 2025,they did not prepare the variety certificate in advance.After the goods arrived at the port,Yangshan Customs required supplementary materials,otherwise they would face the risk of return (loss of about 1.2 million yuan).

After the company contacted Ms.Wei from Zhongshen,Ms.Wei immediately coordinated the cooperative institution of the Thai Ministry of Agriculture,obtained the variety certificate and completed the electronic connection verification within 3 days.At the same time,Ms.Wei assisted in making an appointment for commodity inspection and testing,and the goods were released smoothly on the 5th day after arrival,avoiding return losses and detention fees (about 12,000 yuan).
