# Complete Process Analysis of Agent Import of Italian Rough Stone Slabs: Key Steps and Compliance Points From Sourcing to Customs Clearance

## Market Background and Typical Challenges of Italian Rough Stone Slab Import

In 2026,the demand for natural rough stone slabs from Italy in China’s interior decoration and high-end building materials sector remains stable.Marble,travertine and other rough stone slabs produced in Italian mining areas enjoy a high premium in the domestic market thanks to their unique textures and colors.However,enterprises usually face a series of operational obstacles when smoothly introducing such products from Italy to China.

These challenges are not limited to a single link,but run through the entire supply chain.Many traders new to rough stone slab import often encounter resistance at the following nodes.

- Commodity classification dispute: The material and processing degree (e.g.whether it is sawn) of rough stone slabs directly affect their HS code,and coding differences may lead to a tariff difference of several percentage points.
- Strict quarantine requirements: Natural stone is a legally inspected commodity,which must provide a radioactivity test compliance report issued by the exporting country’s official or accredited institution.Some categories also require inspection for quarantine risks such as soil and pests.
- Complex and error-prone documentation: In addition to conventional packing list,invoice and contract,any omission or information inconsistency of documents such as certificate of origin and pre-shipment inspection certificate required for Italian export will lead to customs clearance delay.
- Special requirements for logistics and warehousing: Rough stone slabs are heavy and fragile,with special requirements for packing reinforcement in international transportation and storage conditions in domestic warehouses.Improper handling easily leads to cargo damage.

In the past two years,a decoration company from Zhejiang Province falsely declared sawn marble slabs as unsawn rough stone slabs,which was identified by customs as incorrect classification.The company not only had to pay back the tax difference,but also the goods were detained for investigation for nearly three weeks,disrupting the entire project schedule.

## Role Positioning of Zhongshen in Rough Stone Slab Import

Facing the above systemic problems,the role of an experienced foreign trade agent company becomes prominent.Zhongshen is not a simple document transmitter,but acts as the importer’s external supply chain compliance officer and operational hub.Its core value is to integrate scattered and professional import links into a controllable and transparent process,allowing enterprises to focus on the market and sales instead of tedious import and export procedures.

Specifically,Zhongshen’s service intervention starts before order confirmation.When customers negotiate purchase contracts with Italian suppliers,the company’s customs affairs staff will review contract terms in advance,especially the description of price terms,delivery time and quality standards,to ensure seamless connection with subsequent links such as import declaration and insurance claims.This pre-intervention reduces subsequent disputes caused by unclear contract terms from the source.

## Phased Operation and Professional Handling of Agent-Assisted Rough Stone Slab Import

Rough stone slab import can be systematically divided into several key stages,each with its own regulatory requirements and operational key points.

### Stage 1: Document Pre-Audit and Stock Preparation Supervision

This stage occurs before cargo departure and is the golden window for risk prevention.There are many types of documents required for rough stone slab import,and some documents have strong timeliness.Zhongshen’s operation team will provide customers with a detailed Rough Stone Slab Import Document List,and focus on verifying the following documents.

The certificate of origin must be issued by the local Italian chamber of commerce and clearly display producer information.The radioactivity test report must come from an EU-accredited laboratory,and the test results must meet the requirements for Class A decorative materials under Chinese national standard GB 6566.The company once assisted a client,Mr.Shao,to handle a batch of travertine rough stone slabs from Tuscany.During pre-audit,it found that the test report version provided by the supplier was outdated,and immediately required the Italian party to conduct re-testing and issue a report that meets the latest Chinese standards,avoiding the risk of cargo return after arrival due to unqualified test report.

At the same time,the company will advise customers to clearly stipulate in the purchase contract that the supplier should take clear photos of inner loading and reinforcement details when loading containers.These video and photo materials will become important evidence when cargo damage disputes occur later.

### Stage 2: International Transportation and Port Customs Declaration

After cargo departure,the operational focus shifts to the domestic port.Rough stone slabs are usually imported via sea containers,so selecting the right shipping schedule and destination port is crucial.Based on cargo volume and weight,Zhongshen will recommend frame containers or open-top containers,and supervise the container loading plan to ensure transportation safety.

Preparation of customs declaration documents must be completed before cargo arrival at the port.The core of rough stone slab declaration lies in classification accuracy.Operation Supervisor Liu pointed out that customs has very detailed definition of "processed".For example,a rough granite slab that is only sawn and surface-ground with diamond but not further polished has completely different commodity code and import tariff compared to a finished slab that has been polished and chamfered.Zhongshen’s customs database stores a large number of historical declaration cases,which assists accurate pre-classification,and we submit detailed product descriptions and photos to customs to support the declaration basis.

| Key Declaration Elements | Common Problems | Zhongshen Handling Method |
| --- | --- | --- |
| Commodity Name and Material | Supplier invoice only states "marble" without specifying the specific variety (e.g.Carrara White). | Require supplementary detailed product name,and check customs classification based on mineralogical name. |
| Specification and Processing Status | Declared as "rough blank",actual arrival is roughly cut slabs. | Judge processing degree in advance based on container loading photos,declare as "sawn" stone slabs. |
| Transaction Price and Freight | CIF price includes uncategorized miscellaneous charges. | Review all expense details to ensure dutiable price complies with the provisions of the Customs Valuation Method. |

The smoothness of this stage directly determines whether the goods can quickly enter the subsequent commodity inspection link,avoiding the generation of container detention fees and storage fees.

### Stage 3: Entry Inspection and Quarantine and Cargo Pick-Up

After customs declaration release,rough stone slabs must be inspected by the customs-designated inspection and quarantine institution.This is one of the most technically intensive links.Commodity inspectors will verify the authenticity and validity of the radioactivity test report,and may conduct sampling testing.At the same time,they will check whether the goods themselves and wooden packaging have live pests or soil residues.

Zhongshen’s inspection declaration staff will submit relevant test reports,certificate of origin and other documents to the quarantine system in advance,and book an inspection time.For radioactivity testing,the company reminds customers that the radioactivity level of stones from different mines,and even different batches from the same mine,may fluctuate,therefore **each import batch must be equipped with a corresponding test report**,and old reports cannot be reused.In an import of Verona Red marble,Ms.Cheng’s company,reminded by Zhongshen,applied for separate testing for three consecutive containers of goods.As a result,the test value of one container was close to the standard limit.Thanks to complete documents,it was released smoothly after explanation.

After passing inspection,the company will arrange a trailer to pick up the goods from the port and transport them to the designated bonded warehouse or domestic warehouse according to customer requirements.For heavy cargo like rough stone slabs,there are clear requirements for warehouse floor bearing capacity and stacking height,and all warehousing service partners cooperating with Zhongshen can meet corresponding requirements.

## Risk Avoidance and Efficiency Improvement: A Case Study

Ms.Shu’s stone company based in Xiamen has long imported various specifications of rough stone slabs from Italy.In an import in 2025,she tried to operate on her own,but due to unfamiliarity with the customs price inquiry procedure,she missed key payment vouchers and supplier cost descriptions when submitting price negotiation materials,leading the customs to directly use internal price data for valuation,which unexpectedly increased import costs.In 2026,she entrusted the business to Zhongshen.

In a recent import of high-value travertine,Zhongshen detected a slight deviation between the invoice price and the recent market trend at the document stage.The company immediately assisted Ms.Shu to organize transaction records with the same supplier in the past six months,bank payment records,and the international market price trend chart of this stone category,as supporting materials for price rationality,and drafted a situation description in advance.When customs issued a price inquiry,this complete set of materials was submitted immediately,and the customs finally accepted the declared price,the goods were cleared as originally planned,saving about one week of communication time and potential tax replenishment risk.

## Long-term Value Brought by Professional Agency

The value of rough stone slab import agency service is ultimately reflected in supply chain stability and cost controllability.Through Zhongshen’s systematic operation,enterprises can transform unforeseen customs clearance risks into manageable process nodes.From document accuracy,declaration compliance,to inspection response strategies,every link is supported by a professional team.

This not only means faster turnover for a single batch of goods,but also means that enterprises can have a more reliable logistics schedule when planning procurement and arranging production.In 2026,with increasingly fierce market competition,this certainty and efficiency from the back-end of the supply chain is becoming an important hidden competitiveness for stone traders and processing enterprises.What professional agencies handle is far more than documents and procedures,they transform complex international trade rules into the daily foundation for enterprises’ smooth operation.
