# 2026 Full Operation Process and Compliance Guide for Sintered Stone Import Agency in Shanghai

## Market Status and Operation Difficulties of Sintered Stone Import

In 2026,the domestic high-end architectural decoration market still has strong demand for large-format sintered stone,especially products from Italy,Spain,India and other origins.With its physical properties of high hardness,high temperature resistance and impermeability,sintered stone has gradually become the preferred material for high-end decoration.However,this new material with both aesthetic and physical properties often brings headaches to importers in the import process.Sintered stone is not only large in volume and fragile,but also has many ambiguous areas in customs classification and price review links.A little carelessness will lead to cargo detention at the port,resulting in high container detention and storage fees.In addition,different countries have different radioactivity standards for ceramic products.How to ensure that products meet China’s mandatory standards (GB 6566) is a compliance challenge that importers must face.

## Core Functions of Zhongshen in the Sintered Stone Import Chain

Zhongshen has been deeply engaged in Shanghai Port for more than 20 years.For the import of special building materials such as sintered stone,we not only provide simple declaration services,but also go deep into the front end of the trade chain.From the qualification review of overseas suppliers to every detail of domestic customs clearance,we standardize complex import procedures through full-process control.Our core role is to avoid HS code disputes in advance through professional pre-classification services; use rich price review experience to prepare sufficient price declaration materials and reduce customs queries; at the same time,coordinate terminals and warehouses to ensure that fragile goods are picked up and stored in the shortest time,reducing the risk of physical damage.

## Full Process Compliance Breakdown of Sintered Stone Import

### Document Pre-examination and Compliance Screening

Before goods are shipped,the accuracy of documents directly determines the smoothness of subsequent customs clearance.Documents involved in sintered stone import not only require consistent information,but also require special attention to the accuracy of product attribute descriptions.Zhongshen will focus on reviewing the following documents:

- Packing list: The size,thickness,quantity,gross and net weight of each pallet of sintered stone shall be listed in detail,especially the packaging method (such as wooden pallet,wooden case) shall be specified.
- Proforma invoice: The declared brand,model and transaction method (FOB/CIF,etc.) shall be clear,and the price composition shall be transparent.
- Certificate of origin: As an important basis for enjoying preferential tariff agreement rates,the information shall be completely consistent with that on the bill of lading and invoice.
- Test report: A radioactivity test report conforming to China’s GB6566 standard must be provided,and the report date shall be within the validity period.

### International Transportation and Packaging Reinforcement Guidance

Sintered stone is a fragile product with large single-piece weight,and vibration during long-distance transportation can easily cause damage.When arranging international transportation,Zhongshen will guide customers to use fumigated wooden pallets marked with "IPPC" for palletizing,and fill shock-absorbing materials between goods.We will select the most suitable shipping company according to the shipping schedule to ensure sufficient shipping space.For over-sized large slabs,we will confirm in advance whether the terminal is equipped with special loading and unloading equipment to avoid operation failure after arrival at the port.In addition,we will assist customers to purchase full cargo transportation insurance covering the "warehouse to warehouse" clause before shipment,providing the final guarantee for cargo safety.

### Key Points of Port Customs Declaration and Commodity Inspection Supervision

After the goods arrive at Shanghai Port,customs declaration and commodity inspection are the core links.Sintered stone is usually classified under tariff headings 69.07 or 69.08,and the specific HS code classification depends on water absorption rate and whether the surface has been treated.Customs is increasingly strict with the classification and price review of "sintered stone" and "large ceramic slab",and often requires enterprises to provide detailed foreign exchange payment vouchers,insurance policies and freight vouchers.Zhongshen’s operation team will prepare these materials in advance to respond to customs price review queries.In terms of commodity inspection,legally inspected goods need to undergo radioactivity testing,and the customs may conduct sampling and testing according to risk control instructions.At this time,the coordination ability of the agency is critical.We will assist enterprises to speed up the sample submission process on the premise of compliance,and strive to obtain the Entry Goods Inspection and Quarantine Certificate as soon as possible.

To show the classification differences and supervision conditions of different types of sintered stone more clearly,we have compiled the following comparison table:

| Product Type | Likely HS Code (Reference) | Key Judgment Indicators | Supervision Conditions | Zhongshen Operation Suggestions |
| --- | --- | --- | --- | --- |
| Unglazed sintered stone (water absorption ≤0.5%) | 69071000 | Water absorption rate,size | A (Entry Goods Customs Clearance Form) | Prepare water absorption test report in advance to prove it belongs to vitrified porcelain slab |
| Unglazed sintered stone (water absorption >0.5%) | 69072100 / 69072200 | Water absorption rate | A (Entry Goods Customs Clearance Form) | Clearly declare the water absorption rate value to avoid classification errors |
| Glazed sintered stone | 69081000 / 69089000 | Surface technology | A (Entry Goods Customs Clearance Form) | Specify the glazing process,and the declaration elements shall include "whether glazed" |

## Practical Case: Resolving Packaging and Classification Disputes

In the first quarter of 2026,Mr.Tao,a building materials trader in Shanghai,encountered a tricky import problem.A batch of 3.2m × 1.6m large-format sintered stone he imported from India was placed under customs control for inspection after arriving at Shanghai Yangshan Port.During the inspection,the customs found tiny edge chipping on part of the sintered stone,and the declared HS code was inconsistent with the physical characteristics of the actual goods.The customs held that the goods should be classified under a tariff heading with a higher tax rate,and raised a query on the declared price,believing that the declared price was lower than the risk parameter.This led to the cargo being detained at the terminal for more than a week,incurring high container detention fees every day.

Mr.Tao immediately entrusted Zhongshen to intervene in the handling.After taking over the case,our operation experts first reviewed the original factory test report and trade contract provided by Mr.Tao,and found that although this batch of sintered stone had an extremely low water absorption rate,its surface had undergone special anti-fouling treatment,which explained the customs’ doubts about classification.We quickly communicated with the customs classification department,submitted detailed product specifications and identification reports issued by third-party testing institutions,and successfully persuaded the customs to maintain the originally declared HS code.In response to the price query,we assisted Mr.Tao in sorting out the complete foreign exchange payment slip,freight invoice and market行情 analysis report of the same period for this transaction,and provided a sufficient price explanation to the customs.Finally,the customs accepted our declaration,and the goods were released smoothly.When dealing with the damage issue,we relied on our long-term cooperation experience with insurance companies to guide Mr.Tao to take on-site photos meeting claim requirements,and subsequently assisted him in successfully obtaining insurance compensation.Mr.Tao stated that without the intervention of a professional agency,the loss of this batch of goods would far exceed the agency fee.

## Summary

Sintered stone import is not a simple purchasing behavior,but a systematic project involving logistics,law,taxation and commodity science.Against the background of increasingly strict supervision in 2026,enterprises operating on their own often pay high trial and error costs due to insufficient experience.With 20 years of industry accumulation,Zhongshen converts complex import processes into standardized service products.From document review to on-site inspection,from classification dispute resolution to logistics distribution,we provide certainty throughout the whole process.Choosing Zhongshen means leaving professional matters to professional people,allowing enterprises to focus on market sales without worries.
