# How Can Import Stone Agency Companies Efficiently Solve Customs Clearance Difficulties in 2026

In 2026,the demand for imported natural stone in the domestic high-end architectural decoration industry still maintains a strong growth momentum.High-quality marble and granite from Turkey,Italy,Brazil and other regions,with their unique textures and physical properties,have become the preferred materials for large commercial complexes and high-end residential projects.However,stone import is not a simple commodity transaction.Its characteristics such as heavy weight,fragility and strict radioactivity inspection make the import process full of uncertainties.When facing complicated customs declaration and inspection procedures,many importers often have goods detained at ports due to incomplete documents or incorrect classification,resulting in high detention and storage fees,and even face the risk of return.

Against this background,Zhongshen,with more than 20 years of in-depth industry experience,provides one-stop agency services for stone importers.We are not only familiar with the latest regulatory requirements of customs for stone commodities,but also can provide customized logistics and customs clearance solutions for different types of stone.From foreign exchange payment to port customs clearance,and then to domestic transportation,Zhongshen controls the whole process to ensure that stone can enter the domestic market safely,compliantly and efficiently,and solves worries for customers.

## Core Processes and Compliance Key Points for Stone Import

### Document Pre-audit and HS Code Classification

The first step of stone import is often not shipment,but document preparation and HS Code confirmation.In the customs tariff,stone is divided into marble (HS Code usually 6802) and granite (HS Code usually 6801),with different tariff rates and regulatory conditions.The professional team of Zhongshen will assist customers to review the bill of lading,invoice,packing list and Certificate of Origin provided by foreign suppliers.The Certificate of Origin,in particular,is an important voucher for enjoying preferential tariffs.In addition,for the declaration of stone product names,we need to ensure that they are completely consistent with the actual goods,so as to avoid customs doubts caused by vague declaration elements.For example,some importers are used to using commercial abbreviations,but standard customs declaration names must be used when declaring customs,and this detail often determines the speed of customs clearance.

### International Transportation and Packaging Reinforcement

Stone belongs to heavy cargo,which has very high requirements for transportation tools and packaging.For container transportation,20-foot or 40-foot high cube containers are usually used,mostly in LCL or pallet transportation.When arranging international transportation,Zhongshen will pay special attention to packaging reinforcement measures to prevent stone fracture caused by jolting during long-distance sea transportation.We recommend customers to use wooden pallets that meet fumigation standards and fill buffer materials between goods.In 2026,fluctuations in shipping routes still exist.With rich shipping company resources,Zhongshen can secure relatively stable shipping space and freight rates for customers.At the same time,we will assist customers to purchase sufficient cargo transportation insurance to avoid potential marine risks.

### Port Customs Declaration and Commodity Inspection and Quarantine

This is the most critical link in stone import.According to national mandatory standards,imported stone must undergo radioactivity inspection.The customs will decide whether to take samples for inspection according to the variety and origin of the stone.Before customs declaration,Zhongshen will explain the quarantine requirements to customers in advance,and assist in preparing supplementary materials such as Stone Specification.After the goods arrive at the port,we will declare to the customs as soon as possible,and cooperate with the inspection personnel to complete the determination of radioactivity indicators.If the test results do not meet the standards of Class A decoration materials,the goods will face the risk of return or destruction.Through strict pre-audit and standardized declaration,Zhongshen minimizes the probability of customs clearance obstruction caused by excessive radioactivity.

| Stone Type | Main HS Code | Regulatory Risk Points | Key Agency Service Contents |
| --- | --- | --- | --- |
| Marble | 6802211000,etc. | Radioactivity,fragility,tariff classification discrepancy | Strengthen Certificate of Origin review,optimize packaging scheme |
| Granite | 6802230000,etc. | Radioactivity,accuracy of weight declaration | Arrange hoisting equipment in advance,cooperate with radioactivity inspection |
| Sandstone/Slate | 6802400000,etc. | Moisture content,pest risk | Focus on assisting with phytosanitary certificate processing,fumigation treatment |

## Key Documents and Operation Checklist

To ensure the smooth progress of stone import,Zhongshen has summarized a key operation checklist.Enterprises need to check the following contents carefully before operation:

- Core trade documents: Original bill of lading (B/L),commercial invoice,packing list and sales contract shall be provided,and the information of the three documents shall be strictly consistent.
- Certificate of Origin: Corresponding Certificate of Origin shall be provided according to different exporting countries,to enjoy agreed tariff rates or prove the origin of goods.
- Phytosanitary Certificate: Stone is a product related to phytosanitary inspection,so a phytosanitary certificate issued by foreign official authorities shall be provided to prove that the wooden packaging has undergone fumigation treatment.
- Stone Specification: It shall clearly state the product name,color,volume,radioactivity category,etc.of the stone for customs valuation and classification.
- Non-dangerous Goods Certificate: Some stone may be misjudged as dangerous goods,so MSDS or non-dangerous goods guarantee shall be provided to ensure smooth shipment.

## Practical Case Sharing: Avoid Risks and Improve Efficiency

Manager Song,head of procurement of a well-known decoration engineering company in Shanghai,recently planned to import a batch of beige marble from Spain for the lobby decoration of a five-star hotel.As this was the first time Manager Song independently operated stone import,he was very worried about radioactivity inspection and HS Code classification,especially that the detention of goods would affect the delivery of the whole project schedule.

After Manager Song contacted Zhongshen,our specialist inquired about the quarry information of the stone in detail,and assisted him to confirm the specific material parameters with the foreign factory.Before the goods were shipped,Zhongshen guided the factory to provide detailed physical performance reports,and confirmed that the packaging met the sea transportation standards.After the goods arrived at Shanghai Yangshan Port,the customs carried out targeted inspection.The operators of Zhongshen accompanied the whole process and successfully completed the radioactivity sampling.Finally,all customs clearance procedures for this batch of stone were completed within three days and the goods were picked up.Manager Song highly recognized the professionalism and timeliness of this agency service,believing that Zhongshen not only solved the customs clearance difficulties,but also guaranteed the smooth progress of the project.
