Full Process Operation Guide and Compliance Key Points for Xiamen Imported Stone Agency

In 2026,the aesthetic preference and demand for natural stone in the domestic high-end building decoration market continue to upgrade.Imported stones such as Turkish marble,Brazilian granite and Spanish sandstone are still the first choice for many projects.Xiamen Port,with its unique geographical location and mature stone processing industrial chain,has long held the leading position in domestic stone import.However,in actual operation,importing stone is not a simple process of trading and transportation.As a natural mineral product,stone has unpredictable physical properties.In addition,customs requirements for radioactivity detection,weight identification,classification and price review are increasingly strict,which leads to many inexperienced importers encountering problems such as cargo detention,document inconsistency or high inspection rate at the port.How to achieve efficient customs clearance in a complex regulatory environment is the core issue facing current stone traders.

Core Role of Zhongshen in the Stone Import Chain

Facing the strict regulatory environment of Xiamen Port,Zhongshen has built a set of agency service system specifically for bulk stone import relying on more than 20 years of practical experience in the industry.We are not only the executor of customs declaration and inspection,but also the manager of customers’ supply chain risks.In the process of stone import,Zhongshen intervenes in the trade link in advance to pre-review the foreign shipping documents to ensure the accuracy of source information; in the transportation link,we coordinate shipping companies and port resources to optimize manifest data; in the customs clearance link,we use professional classification knowledge to respond to customs queries.This in-depth participation in the whole process can effectively cut off the chain of customs clearance delay caused by document defects or operational errors.

Disassembly of Compliance Operation for the Whole Stone Import Process

Stone import involves many links,and any omission in any link may lead to the stagnation of the overall progress.We disassemble the whole process into three key stages,and elaborate the compliance requirements and Zhongshen’s response strategies in detail.

Pre-shipment Document Pre-review and Compliance Confirmation

Before the goods are loaded and depart from the port of shipment,the accuracy of documents determines the smoothness of subsequent customs clearance.The focus of document review for stone import lies in the consistency of product name,specification and radioactivity test report.Zhongshen’s operation team will confirm the following key document elements with customers before shipment:

• Certificate of Origin and Test Report: Ensure that the information on the Certificate of Origin is consistent with the bill of lading,and a radioactivity test report issued by a qualified institution must be attached.For different lithologies such as marble and granite,the classification of the report must be accurate.
• Packing List and Weight Data: Stone is usually priced by weight,so the gross weight and net weight on the packing list must be accurate to two decimal places.Zhongshen will assist customers to check the weight data provided by foreign suppliers,so as to avoid subsequent customs price review risks caused by quantity differences.
• IPPC Mark: Check whether the wooden pallets used for stone packaging have pest control treatment marks,which is a key focus of customs animal and plant quarantine.The absence of this mark will directly lead to return or destruction of goods.

International Transportation and Preparation for Port Arrival Declaration

The international shipping market in 2026 still has fluctuations in shipping capacity.Zhongshen uses long-term accumulated resources of shipping companies to secure stable shipping space and reasonable freight rates for customers.Before the goods arrive at the port,we will submit the manifest declaration to the customs in advance and prepare customs declaration elements simultaneously.For the possible "more or less" situation of stone,we will set a reasonable error range in the contract terms in advance,and truthfully explain it when making customs declaration,so as to avoid being identified as false declaration by the customs.In addition,for some stone goods that require "two-step declaration",we will first complete the summary declaration to ensure that the goods are lifted off the dock and reduce the occurrence of port detention fees.

Customs Declaration and Statutory Commodity Inspection at Xiamen Port

This is the most challenging link in stone import.Xiamen Customs implements statutory inspection on imported stones,among which radioactivity detection is the top priority.Zhongshen is familiar with the operation procedures of each inspection site at Xiamen Port,and can assist customers to cooperate with the customs in on-site inspection.

When making customs declaration,the classification of HS Code directly determines the tariff rate and supervision conditions.For example,there are differences in classification between some roughly cut marble blocks and surface-treated slabs.Zhongshen’s customs declaration experts will carry out accurate classification according to the actual processing degree of the stone and in accordance with the Import and Export Tariff,so as to neither underpay taxes and cause risks nor overpay taxes and increase costs.At the same time,in response to the customs’ query on the price of stone,we provide international market price references of similar products to assist customers in completing price negotiations.

Common Risk Avoidance and Practical Case Sharing

In our long-term agency service,we have handled various complex stone import cases.At the end of 2025,a manager engaged in high-end hotel decoration customization contacted us.He imported a batch of statuario marble from Italy.After the goods arrived at Xiamen Port,they were placed under customs control for inspection,and customs clearance was suspended because the radioactivity test value was at the critical value.At the same time,the customs questioned that his declared price was lower than the risk threshold.He was facing great pressure of tight project schedule,and would face high liquidated damages in case of delay.

After Zhongshen intervened,we first launched the emergency plan.We assisted the manager to contact a professional testing institution with CMA qualification,and conducted a re-inspection under the supervision of the customs,confirming that this batch of stone met the national Class A decoration material standard.In response to the price query,we retrieved the customer’s past import records and the fair price proof of international stone transactions in the same period,and submitted a detailed situation description and evidence materials to the customs.After multiple rounds of communication and consultation,the customs finally recognized the declared price and released the goods.Through this operation,we not only helped the manager avoid the risk of return,but also saved him about 5% of tariff cost through professional classification explanation.This case fully shows that professional agency services can play a decisive role at critical moments.

Long-term Value of Professional Agencies for Stone Import Business

Under the foreign trade environment in 2026,compliance cost and efficiency cost have become expenses that enterprises cannot ignore.When choosing Zhongshen as the import agent,enterprises can not only get faster customs clearance speed,but also establish a sense of compliance security.For the import of non-standard,high-risk mineral products such as stone,professional agents can turn uncertain customs clearance obstacles into controllable standard processes through risk prediction,accurate operation and effective communication.This enables enterprises to focus more on market sales and product improvement,rather than complicated port affairs.Zhongshen will continue to optimize the service process,commit to providing every customer with a transparent,efficient and low-risk stone import agency experience,and ensure that every piece of precious stone can be delivered to the project site on time and in compliance with regulations.
