Full-process Analysis and Detailed Compliance Operation Guide for Quartz Stone Import Agency

In 2026,with the recovery and upgrading of the domestic high-end architectural decoration industry,the market demand for imported quartz stone shows a trend of refinement and customization.Traditional stone exporting countries such as Brazil,India,Turkey and Spain are still the main source countries.However,importing quartz stone is not a simple purchase and sale transaction,and the hidden compliance risks behind it cannot be underestimated.Many traders new to this field often have goods detained at the port due to insufficient understanding of the "legal inspection" process or ignoring the strict standards of radioactivity testing.Against the background that the General Administration of Customs continues to strengthen port supervision,how to unblock the import chain and ensure compliance and efficient customs clearance of goods has become a core problem that enterprises need to solve urgently.

Disassembly of Full Import Process and Compliance Operation

Document Pre-review and Risk Assessment

The first barrier to quartz stone import lies in the accuracy of documents.Before the cargo departs from the origin port,Zhongshen will assist customers to conduct strict pre-review on the full set of documents,with focus on certificate of origin,test report and bill of lading information.Especially for the radioactivity test report of stone,it must comply with national mandatory standards.The professional team of Zhongshen will check the specific activity of radioactive nuclides such as radium,thorium and potassium in the report,ensure that the product belongs to Class A decorative materials that can be used for residential interior decoration.If abnormal data is found in pre-review,we will immediately advise customers to replace or rectify before shipment,and intercept risks outside the border.

Key Document Preparation Checklist

• Certificate of Origin: Original document required,to confirm the applicability of preferential tariff agreements.
• Radioactivity test report: Issued by a qualified third-party institution,with clear definition of stone category.
• Composition description: Detailed list of quartz content,resin adhesive ratio and other additives.
• Packing list and commercial invoice: Weight,volume and number of packages must be fully consistent with the actual cargo.

Port Customs Declaration and Statutory Commodity Inspection

After the cargo arrives at the port and is declared,as a legally inspected commodity,quartz stone must follow the process of "inspection first,customs declaration later".Zhongshen is mainly responsible for classification declaration to customs at this stage.Quartz stone slabs are usually classified under tariff heading 68.02,while quartz sand or quartz powder may be classified under 25.06 or 28.02.Wrong classification directly affects the tax rate and supervision conditions.In the commodity inspection link,the customs will conduct radioactivity verification according to regulations.With rich operation experience,Zhongshen can coordinate with the terminal to cooperate with inspection in advance,optimize the process of sending sampling samples for testing,shorten the detection cycle,and ensure rapid release of goods on the premise of compliance.

Practical Case: Avoiding the Risk of Excessive Radioactivity

At the end of 2025,Mr.Ma,a trader engaged in high-end stone trade,entrusted Zhongshen to act as the import agent for a batch of quartz stone slabs from Turkey.After the goods arrived at Yangshan Port,Shanghai,the customs ordered a radioactivity test.The initial test result showed that the radium specific activity of this batch of stone was slightly higher than the standard limit of Class A,facing the severe situation of being returned or destroyed.Mr.Ma was very anxious because this batch of goods involved breach of contract compensation for the downstream decoration project schedule.

The operation specialist of Zhongshen did not stay inactive,but immediately compared the test report from the exporting country with the domestic initial test data for analysis.We suspected that the result was caused by uneven sampling location or detection error.With the consent of the customs and on the premise of assisting Mr.Ma to pay the deposit,Zhongshen assisted in applying for re-inspection,and guided the quarantine personnel to re-sample from different parts of the stone.Finally,the re-inspection result confirmed that this batch of stone meets the Class A standard,and cleared customs smoothly.This process not only avoided hundreds of thousands of losses from return shipment for Mr.Ma,but also protected his business reputation.
