How Import Goods Agents Solve Customs Clearance and Quarantine Problems

I.Background and Common Difficulties of Importing Tropical Fruits

In 2026,Ms.Gao from a Shanghai-based trading company planned to import a batch of Thai Monthong durian to hit the market before the Dragon Boat Festival,but encountered difficulties in early preparation.Among the documents provided by the Thai supplier,the validity period of the phytosanitary certificate was vaguely marked.Meanwhile,China’s 2026 quarantine standards for Southeast Asian fruits had just been updated,requiring an additional special test report for Bactrocera dorsalis.Ms.Gao visited the customs for consultation several times but still could not figure out the specific requirements.She was extremely anxious as the cargo ship was about to arrive at the port.

This is not an isolated case — with the further deepening of RCEP regional trade in 2026,the demand for imported Southeast Asian tropical fruits from Shanghai enterprises increased by 32% year-on-year,but problems such as document compliance,quarantine qualification,and port customs clearance efficiency have become major obstacles for many enterprises.Tropical fruits are perishable goods,every day of delay may lead to more than 10% loss,and unqualified quarantine may even result in the risk of destroying the entire batch.

II.Core Role of Zhongshen in Import Agency

As a service provider with over 20 years of experience in import agency based in Shanghai,Zhongshen has built a full-process control system from document pre-examination to port release for goods with extremely high requirements on timeliness and quarantine such as tropical fruits.Unlike ordinary agents that only handle "entry-level customs declaration services",the core value of Zhongshen lies in Proactive Risk Screening and Accurate Alignment with Compliance Requirements — for example,checking the 2026 updated quarantine standards of customs in advance,guiding suppliers to supplement special test reports,and avoiding enterprises finding problems only after the cargo ship arrives at the port.

III.Stage-by-Stage Breakdown of Import Process and Exclusive Services

1.Document Pre-Examination: Proactive Screening to Prevent Non-Compliant Declaration

After China Customs updated the document requirements for imported fruits in 2026,in addition to conventional commercial invoices,packing lists and bills of lading,it is also required to provide Phytosanitary Certificate Issued by Official Authority of Origin (including special pest and disease testing),Certificate of Registered Orchard/Packing Plant for Fruits Exported to China.Among the documents Ms.Gao initially received,the special test page for Bactrocera dorsalis was missing,and the registration number on the packing plant certificate had expired.If declared directly,the application would not only be rejected,but also the goods may rot due to overdue declaration.

After receiving the request,Zhongshen’s document team immediately checked the latest 2026 document template of Thai Customs,and found that the certificate format provided by the supplier did not meet the coding requirements of China Customs.The team immediately contacted the Thai supplier,guided them to supplement the special test report and update the packing plant certificate.The entire pre-examination process only took 1 working day,avoiding delays after the cargo ship arrived at the port.

2.Port Customs Declaration: Accurate Connection with Intelligent System to Improve Efficiency

There are two special requirements for port customs declaration of tropical fruits: first,declaration must be made within 24 hours after the goods arrive at the port (otherwise an overdue declaration fee will be charged),second,the customs declaration form must be marked with "perishable goods" for priority inspection.In 2026,the customs declaration system of Shanghai Port has been upgraded to "intelligent examination".If the document information does not match the system database,it will directly trigger manual inspection,which may extend the processing time to 3-5 working days.

Zhongshen’s customs declaration team entered the pre-examined documents into the customs intelligent system in advance,checked the code of each item of information (for example,the HS code of durian is 0808100000,which needs to be marked as "fresh durian" instead of "frozen durian"),and completed pre-declaration 12 hours before the goods arrived at the port.After the cargo ship docked,the system directly approved the documents,and completed customs declaration and release in only 4 hours,which is nearly 60% faster than the conventional process.

3.Commodity Inspection and Quarantine: Targeted Verification to Avoid Pest and Disease Risks

In 2026,China added Brontispa longissima,Bactrocera dorsalis and other pest and disease tests to the quarantine focus for Southeast Asian fruits,requiring on-site sampling inspection at the port.If a positive result is found,the goods will be destroyed immediately.Ms.Gao once heard that a peer had 30 tons of durian destroyed due to unqualified inspection,with a loss of more than 200,000 RMB.

Zhongshen’s commodity inspection team communicated with Shanghai Entry-Exit Inspection and Quarantine Bureau in advance,learned that the sampling ratio for Thai durian in 2026 is 5% (3% for conventional fruits),and prepared the tools and recording templates required for sampling in advance.After the goods arrived at the port,the team assisted quarantine personnel to complete sampling,and obtained the qualified inspection report in only 8 hours,avoiding the rot risk caused by goods being detained in the quarantine area.

IV.Actual Case: Key Operations to Avoid Millions of Losses

At the end of 2025,Manager Wang from a Shanghai food trading company imported a batch of Vietnamese pitahaya.Due to the lack of document pre-examination in advance,the customs found that the orchard registration number on the certificate of origin did not match the registration list for export to China during declaration,and the goods were detained.When Manager Wang contacted Zhongshen,the goods had been detained at the port for 3 days,and the pitahaya began to show signs of rot.

Zhongshen’s emergency team intervened immediately,with core actions including:

• Contact the Vietnamese supplier immediately to verify the update of the orchard registration number,and guide them to re-issue a compliant certificate of origin;
• Communicate with the customs synchronously,explain that the goods are perishable,and apply for priority inspection;
• Coordinate with the warehousing team to transfer the goods to a constant temperature warehouse to slow down the rate of rot.

The entire process took only 2 working days,and the goods were released smoothly.In the end,only about 5% of the pitahaya was lost,which reduced the loss by nearly 1.2 million RMB compared with the 30% loss estimated by Manager Wang.

VI.Value Summary of Professional Import Agency

In 2026 cross-border trade,compliance requirements for imported goods are becoming more and more detailed,and timeliness requirements are getting higher and higher.Especially for perishable and quarantine-regulated goods,a little carelessness will cause huge losses.As an import agent with more than 20 years of deep experience in the industry,Zhongshen is not only familiar with the special compliance requirements of various types of goods,but also can help enterprises improve customs clearance efficiency by more than 30% and avoid 90% of common compliance risks through proactive pre-examination,intelligent connection,emergency response and other methods.

For foreign trade enterprises in Shanghai,choosing the right import agent is not just "finding someone to handle customs declaration",but finding a partner who understands industry rules,can respond quickly and avoid risks.As Ms.Gao said: "Leave professional matters to professional people,so that we can focus on the market and customers."
