# 2026 Complete Process Analysis and Practical Guide to Cost Control for Xiamen Stone Import Customs Clearance Agency

As the largest stone import port on the southeast coast of China,more than 15% of average daily containers arriving at Xiamen Port in 2026 are loaded with natural stone from Brazil,India,Turkey and other regions.For these goods from berthing to warehousing,customs clearance efficiency directly affects the capital turnover rate of stone traders like Mr.Hu.Different from ordinary goods,stone import is subject to multiple regulatory requirements including radioactivity testing,commodity classification,certificate of origin verification,etc.Discrepant documents or declaration errors may lead to cargo detention at the port and incur high fees.Headquartered in Shanghai,Zhongshen’s service network covers major ports including Xiamen.It has handled more than 800 shipments of stone import business in the past 20 years,and is familiar with the supervision logic and operation details of Xiamen Customs.

## Stage 1: Import Qualification Preparation and Document Pre-audit

The core goal of this stage is to ensure that the import subject has legal qualifications,and all documents meet the audit standards of customs and commodity inspection authorities.Key actions include obtaining valid import and export operation rights,accurately confirming the HS code of the stone,auditing the format and content of the certificate of origin,and obtaining the radioactivity test report.In 2026,customs implements stricter standards for stone radioactivity testing,and some granite varieties need to provide Class A decoration material certification issued by third-party laboratories.Common problems are concentrated in wrong HS code classification,for example,classifying marble products under 6802 or 6803,the tax rate difference can reach 5 percentage points; inconsistent certificate of origin format directly leads to inability to enjoy agreement tariff rates.Zhongshen provides pre-classification services in this link,identifies document defects in advance through historical case database comparison,and avoids problems being discovered only after the cargo arrives at the port.Last year,a shipment of Indian stone owned by Mr.Hu was denied tariff preference by customs because the certificate of origin lacked the back page description.Zhongshen found this problem before shipment,promptly notified the foreign supplier to reissue the certificate,and saved about 30,000 RMB in tax.

## Stage 2: Cargo Arrival and Customs Declaration & Inspection

After the cargo arrives at Xiamen Port,declaration must be completed within 14 days,otherwise you will face a fine for delayed declaration.The goal of this stage is to complete all declaration procedures within the specified time and start the inspection process.Specific operations include exchanging documents with the shipping company,entering customs declaration data,submitting inspection materials to the inspection and quarantine system,and reserving inspection time.In 2026,Xiamen Customs launched the "advanced declaration" mode,allowing enterprises to submit customs declarations 3 days before the cargo arrives at the port,but the manifest data must be 100% consistent with the declaration information,otherwise the system will automatically reject the declaration.Common problems include inability to declare due to inconsistent manifest data,and increased storage fees caused by delayed inspection instruction issuance.Zhongshen connects directly to customs data through an electronic declaration system,reducing the average declaration time from 4 hours to 30 minutes.At the same time,Zhongshen maintains a daily communication mechanism with inspection yards in Xiamen Haicang Port and Dongdu Port,and can prioritize inspection arrangements to avoid cargo accumulation at the port.

## Stage 3: Tax Calculation and Payment

Accurate calculation and timely payment of various taxes and fees is the core task of this stage.Stone import involves tariffs and value-added tax,and some varieties also require anti-dumping duties.Key actions include checking the customs-assessed dutiable value,confirming the applicable preferential tax rate,calculating the total tax amount,and completing payment through the electronic payment system.In 2026,customs has tightened price assessment for stone,especially marble from Turkey,and customs will compare it with the transaction price of similar goods recently.Common problems focus on customs price assessment queries,for example,customs considers the declared price too low and requires supporting documents such as payment vouchers and original factory invoices; disputes over anti-dumping duty determination also occur from time to time,such as whether quartz stone products fall within the scope of products subject to anti-dumping duties.Zhongshen gives full play to its professional advantages in this link,prepares complete price assessment basis in advance,including the 2026 price report released by the International Stone Association,the long-term procurement contract between Mr.Hu and foreign suppliers,etc.and assists enterprises to communicate effectively with customs.Through reasonable defense,the amount of additional tax due to price adjustment can be reduced by more than 60% on average.

## Stage 4: Inspection,Release and Pickup & Distribution

The inspection link directly determines whether the cargo can be released in time.The goal is to pass the joint inspection of customs and commodity inspection,complete the pickup procedures quickly,and avoid incurring container detention fees and storage fees.Key actions include cooperating with customs open-box inspection,handling abnormal problems found during inspection,completing release procedures,and arranging trailer pickup.In 2026,the inspection rate of stone by Xiamen Customs is about 30%,with key checks on whether the product name,specification and quantity are consistent with the declaration,and whether radioactivity exceeds the standard.Common problems include the need for return shipment or rectification if radioactivity exceeds the standard,and cargo shortage disputes caused by packaging damage.Zhongshen has a full-time coordinator at the inspection site,who can feed back inspection results in real time.Once,the radioactivity test value of a shipment of Brazilian granite was close to the critical value.Zhongshen coordinated the laboratory for an urgent re-inspection,supplemented and submitted the radioactivity background data of the foreign mine,and finally obtained release,avoiding the loss of returning the entire container.After release,Zhongshen’s logistics team can arrange same-day pickup,control the container detention time within 3 days,and saved Mr.Hu nearly 5,000 RMB in container detention fees.

## Stage 5: Foreign Exchange Settlement and Cost Control

After customs clearance is completed,importing enterprises need to complete outward payment and calculate the overall import cost.The goal of this stage is to complete foreign exchange payment in compliance,lock in a reasonable exchange rate,and achieve cost transparency.Key actions include applying for payment from the bank,checking port and agency bills,and conducting cost-benefit analysis.In 2026,the fluctuation of RMB exchange rate intensifies.The cycle from ordering to payment for stone import is as long as 60 days,so exchange rate risk is significant.Common problems include increased cost caused by exchange rate fluctuation,and disputes over hidden fees such as port miscellaneous fees and storage fees.Zhongshen provides a full-process fee list,and issues a detailed cost estimate before the cargo arrives at the port,covering all items including tariffs,value-added tax,port fees,agency fees,etc.with the error rate controlled within 3%.For exchange rate risk,Zhongshen cooperates with multiple banks to provide forward exchange locking service for clients like Mr.Hu,locking the exchange rate when placing the order to avoid subsequent fluctuation losses.Through Zhongshen’s centralized procurement advantage,port operation fees,trailer fees,etc.can get a 10-15% discount,further reducing the overall cost.

| Stone Type | HS Code | Supervision Condition | 2026 Most Favored Nation Tariff Rate | Special Requirements |
| --- | --- | --- | --- | --- |
| Raw Marble Ore | 25151100 | 7AB | 4% | Required to provide Class A radioactivity test certificate |
| Raw Granite Ore | 25161200 | 7AB | 4% | Certificate of origin required,anti-dumping duty applicable to some varieties |
| Marble Slabs | 68022110 | AB | 10% | Required to indicate processing technology,thickness ≥ 2cm |
| Quartz Stone Products | 68101910 | AB | 15% | Required to confirm whether falls within anti-dumping scope |
