Xiamen Rough Stone Import Process Breakdown: Compliance Path from Overseas Mines to Domestic Factories

I am Manager Zhu,handling import and export agency at Zhongshitong for over twenty years.Today,let’s cut to the chase and dive directly into a specific but risk-intensive business: importing rough stone via Xiamen Port.Whether it is marble,granite blocks,or other ore raw materials,this business sounds rugged,but a slight slip in operational details can cause costs to spiral out of control instantly.

When many clients come to us for the first time,they often fall into a misconception: believing that rough stone is a natural mineral and can be declared as general cargo.In reality,Customs and Commodity Inspection authorities scrutinize it extremely strictly.In 2026,with the upgrading of environmental and bio-safety supervision,the inspection priorities for such goods at Xiamen Port have shifted significantly.

1.Rough Stone Import: Far More Than Just "Hauling Stones"

The core contradiction in rough stone import lies in the conflict between the "non-standard attributes" of the cargo itself and the "standardized supervision" requirements of Customs and Inspection.Every batch of rough stone may differ in size,quality,and mine source,yet declaration requires classifying it into a precise HS Code and providing clear declaration elements.

A Real Lesson: Last year,we took over a batch of Southeast Asian granite rough stone for Mr.Yao.The previous agent simply declared it as "other granite rough stone." As a result,the Customs system routed it for control,requiring detailed "color," "pattern description," and "radioactivity level test reports." Because pre-inspection was not done,the cargo was detained at the terminal for 15 days,and demurrage and storage charges alone exceeded 8% of the cargo value.

This leads to the first hardcore operation point for rough stone import: Precise HS Code classification and completeness of declaration elements. Different codes entail vastly different tariffs and supervision conditions (e.g.whether an import license or species proof is needed).For example,rough stone involving specific wood types or wood fossils that might carry soil or insect eggs must obtain the Entry-Exit Animal and Plant Quarantine Permit in advance.

2.Breakdown of Operational Difficulties: Valuation,Inspection,and Licenses

We break down the entire process into three links most prone to "bottlenecks."

1.Customs Valuation: How to Handle "Price Queries"

The overseas procurement model for rough stone varies; it could be EXW mine pickup or CIF Xiamen arrival.Customs scrutinizes declared prices closely,especially for purchases from related companies or sources with significant price fluctuations.Our approach is to intervene at the contract signing stage to assist clients in preparing a complete "chain of price explanation"—including payment vouchers,mine purchase invoices,third-party valuation reports,and international price trends for similar products—and submit them with the declaration.This proactively resolves subsequent queries and avoids demurrage caused by valuation delays.

2.Pre-inspection and On-site Inspection by Commodity Inspection (now Customs Inspection)

This is the most time-consuming link in Xiamen rough stone import.Inspection focuses on three main areas:

• Quality and Specifications: Whether they match the declaration and if there are any impurities.
• Safety and Sanitary Items: Mainly radioactivity testing,which must comply with national standard GB 6566-2010.We recommend conducting pre-shipment inspection at the port of loading to obtain a qualified report.
• Animal and Plant Quarantine: Checking for soil,live insects,grass seeds,etc.For rough stone from epidemic areas,the inspection rate is nearly 100%.

In practice,we often encounter inspection sites that lack conditions for unloading large rough stone blocks.In such cases,communicating with the terminal and Customs Inspection Department in advance to book heavy machinery and specific inspection platforms can save several days.This is the value of a localized service network.

3.Import Licenses and Species Proofs

Not all rough stone requires them,but once needed,they are a "red line" where no release is granted without a certificate.This mainly involves two types:

• Import License: If the product involves restricted mineral imports by the state.
• Non-Endangered Species Proof / CITES Certificate: For stone materials that may involve endangered species (such as certain specific colored travertines or some fossils),a certificate must be issued by the CITES management authority of the exporting country,and a Species Proof must be processed domestically.

The table below summarizes the regulatory points for common rough stone types.You can quickly find where you fit in:

3.Cost Black Holes and Risk Control: Hidden Costs Agents Might Not Tell You

Beyond sea freight and tariffs,the hidden costs of rough stone import are the "primary eroders" of profits.

• Demurrage Trap: The free container time and free storage time given by shipping companies are usually very tight.If delays occur due to incomplete documents or inspections,daily costs can run into hundreds of dollars.Our risk control move is to complete all document pre-audits 7 days before the ship arrives,ensuring "documents ready upon ship arrival," and securing longer free container time for clients.
• Additional Inspection Fees: Customs inspection itself is free,but lifting,moving,short-haul transport,and third-party testing costs are borne by the cargo owner.For rough stone weighing tens of tons,this expense can be staggering.Advance planning and selecting terminals and trucking companies with good cooperation can effectively control this part of the cost.
• Exchange Rate Risk: The cycle from payment to sales collection is long,and exchange rate fluctuations can erode profits.We usually advise clients to use financial tools like forward exchange settlement to hedge.

4.Practical Case: Problem Solving Under the S-T-A-R Principle

Situation (S): At the end of 2025,Ms.Wan imported a batch of natural sandstone rough stone from Vietnam for high-end landscaping.Upon arrival at Xiamen Port,the Customs system prompted a need for inspection to verify whether it involved endangered species.

Task (T): Time was tight; the client had signed a delivery contract for the landscaping project,and delays would incur high liquidated damages.The task was to immediately clarify the cargo attributes,complete the inspection,and ensure release.

Action (A): Our team first retrieved the detailed origin certificate and mine data of the cargo and quickly contacted a domestic identification agency certified by the forestry department to arrange on-site sampling.Simultaneously,using our daily communication channels with Xiamen Customs,we explained the situation to strive for simultaneous inspection and identification sampling,avoiding a second container opening.We also assisted the client in preparing complete supply chain documents to prove that the sandstone vein was not in the CITES catalog.

Result (R): Within 3 working days,we obtained the "Non-Endangered Species Identification Report" from the authoritative body.After Customs reviewed the full set of documents,the inspection passed,and the cargo was smoothly released on the 5th day after arrival—nearly 10 days faster than the client expected,safeguarding the project schedule.

Zhongshitong is headquartered in Shanghai,but Xiamen rough stone import is a typical embodiment of our capability for "cross-port remote declaration and global network synergy." We don’t just have partners in Xiamen; we seamlessly integrate the complex commodity classification experience,valuation dispute resolution skills,and risk control systems accumulated at Shanghai HQ into the specific operations at Xiamen Port.

When your rough stone is loaded in Africa or South America,our overseas agents can initiate pre-shipment inspection and document auditing; while the cargo is in transit,our Shanghai document center starts classification pre-audit and license processing; when the ship docks in Xiamen,local on-site colleagues immediately interface with the terminal and Customs.This full-chain service of "front-end prediction,mid-process control,and end-stage efficient execution" is the core that truly reduces comprehensive logistics costs and mitigates compliance risks for enterprises.

Finally,a practical word: the value of a rough stone import agent does not lie in filling out a few customs forms for you,but in using our experience and resource network to clear the mines you might not see in advance,ensuring every cent you spend on overseas procurement is solidly transformed into goods in your warehouse.If you are planning or encountering related issues,why not let us reorganize the process for you with a professional perspective.
