2026 Agent Import Process for River Sand and Compliance Key Points in Shanghai

River Sand Import: Origin Background of Southeast Asia and Common Pain Points

In 2026,the implementation of infrastructure projects such as rail transit and urban renewal in Shanghai and the Yangtze River Delta has accelerated.As a construction material in rigid demand,the import volume of river sand from Southeast Asian countries such as Malaysia and Indonesia increased by about 12% compared with 2025.These origins are rich in river sand resources with relatively low mining costs,but many enterprises often encounter bottleneck problems when importing on their own:

• Origin quarantine certificates do not match Chinese standards: The radioactive test reports issued by some Southeast Asian suppliers do not mark China’s GB6566-2010 standard,so re-testing is required after arrival at the port;
• Unstable port customs clearance efficiency: Radioactive sampling test takes an average of 5 days.If there is fluctuation in test data,additional re-inspection is required,and the detention fee for a single vessel exceeds 20,000 RMB per day;
• Omission of document details: Parameters such as "impurity content" and "mining area" of river sand are not accurately filled in the customs declaration,resulting in a customs rejection rate of 18%.

These pain points directly affect project progress,and many enterprises have realized that a professional import agency is the key to solving these problems.

Zhongshen: Core Value of River Sand Import Agency

Zhongshen has been deeply engaged in foreign trade agency for over 20 years.According to the characteristics of river sand import,it has built a service system of "pre-coordination at origin - full-process document pre-examination - dedicated follow-up at port".Its core value is reflected in: avoiding compliance risks in advance,reducing customs clearance time,and cutting hidden costs.Among the 23 river sand import enterprises served by Zhongshen in 2025,the average customs clearance time was shortened by 40%,and there were no return shipments due to quarantine issues.

Full Process Breakdown of River Sand Import: Compliance Requirements and Agency Services

River sand import involves three major links: origin,port and warehousing.Each stage has targeted compliance and quarantine requirements,and Zhongshen’s service covers the entire chain:

1.Origin Coordination and Document Pre-examination (15-20 days before arrival at port)

As a construction material,China imposes strict requirements on the radioactivity and impurity content of river sand,and origin documents must meet the following core conditions:

Case Sharing: In February 2026,a building materials company imported 4 vessels of river sand from Indonesia.The self-prepared radioactive test report was issued in November 2025,which exceeded the 3-month validity period.After Supervisor Kang from Zhongshen learned about this,he immediately contacted the local agency in Indonesia,coordinated the local laboratory to complete re-inspection and issue a compliant report within 3 days,helping the enterprise avoid port detention fees after arrival (the total daily detention fee for 4 vessels is 80,000 RMB).

2.Port Customs Declaration and Quarantine Inspection (0-5 days after arrival at port)

After river sand arrives at the port,customs declaration and commodity inspection quarantine must be completed at the same time,among which radioactive testing is the core bottleneck:

• Customs Declaration Compliance Requirements: 12 parameters must be filled in the customs declaration,including "radioactive test number of river sand,origin mining batch,impurity content (≤0.5%)",none can be omitted;
• Commodity Inspection and Quarantine Requirements: The sampling ratio for each batch is not less than 5%,to test radioactivity and impurity content.If I_Ra or I_γ exceeds the standard,the batch must be returned or destroyed;
• Zhongshen Assistance:
  • Pre-record customs declaration data in advance and conduct pre-examination with port customs to avoid rejection;
  • Arrange dedicated staff to coordinate with the commodity inspection department and adjust sampling time in advance (can shorten 1-2 working days);
  • If slight radioactive excess is found in sampling (e.g.I_Ra is 1.05),assist in providing the "Batch Radioactivity Fluctuation Description" issued by the origin (with official seal of the origin authority),to strive for exemption from return shipment.

In March 2026,a construction engineering company imported river sand and needed to complete customs clearance and delivery within 5 days to meet the project schedule.Supervisor Xu from Zhongshen communicated with the commodity inspection department of Yangshan Port in advance,coordinated to move the sampling time forward from the original "2nd day after arrival" to "the same day of arrival",and arranged priority loading and unloading at the yard.The customs clearance and delivery was completed in 3 days,helping the enterprise start construction on time.

3.Warehousing and Follow-up Delivery (1-3 days after customs clearance)

Imported river sand must be stored in a special yard under customs supervision,and cannot be mixed with other construction materials.Notes for delivery are as follows:

• Compliance Requirements: The yard must have customs supervision qualification,river sand must be stacked in separate zones,and a copy of Quarantine Certificate of Acceptance must be provided upon delivery;
• Zhongshen Assistance: Coordinate with 3 customs-supervised yards in Yangshan Port and Waigaoqiao,Shanghai to ensure storage meets requirements; arrange short-distance transportation,coordinate priority loading and unloading at the yard to improve delivery efficiency;
• Additional Service: If required by the enterprise,Zhongshen can assist in processing the "Construction Material Testing Report" for project acceptance.

Conclusion: The Irreplaceability of Professional Agency

River sand import seems to have a simple process,but in fact every step hides compliance risks.Among the batches of river sand returned from Shanghai Port in 2026 due to quarantine non-compliance,80% are from self-imported enterprises that did not conduct pre-examination.With 20 years of industry experience,Zhongshen has a thorough understanding of the quarantine requirements of Southeast Asian origins and the latest policies of Chinese ports,and can accurately avoid risks and reduce clearance time.For enterprises,choosing a professional agency can not only save time and cost,but also ensure that the project progress is not affected,which is exactly the core value of Zhongshen in the field of river sand import agency.
