# Zhongshen: 2026 Compliance Guide for Stone Import Customs Declaration Agency

## Background and Common Pain Points of Stone Import Customs Declaration

In the first half of 2026,the total import volume of stones such as marble and granite at the Port of Shanghai reached 182,000 tons,of which high-end stones imported from Italy and Turkey accounted for more than 60%.Many local decoration companies and building material traders in Shanghai reported that stone imports are often held up due to discrepant certificates of origin and non-compliant radioactivity test results.For customs clearance delay alone,the loss per shipment exceeds RMB 5,000 per day.

Manager Gao has been in charge of Zhongshen’s stone import agency business for 10 years.He mentioned that the difficulties of stone import are concentrated in three aspects: first,strict origin compliance requirements,some countries require the certificate of origin to mark the longitude and latitude of the mining site; second,multiple quarantine indicators,radioactivity and harmful impurity testing must meet both national standards and the requirements of the importing country; third,various types of documents,12 categories of documents need to be matched one by one,and missing items will lead to document rejection.

## Core Role of Zhongshen in Stone Import

The core role of Zhongshen is to help customers turn "passive customs clearance" into "active compliance".Ms.Jiang,head of the customs declaration department,gave an example: last year,a customer imported a batch of gray granite from Turkey,and the declaration was rejected due to missing longitude and latitude information on the certificate of origin when declaring on their own,resulting in a 3-day delay and RMB 20,000 compensation to the construction party.Later,the customer engaged Zhongshen as the agent.Supervisor Zhuang reviewed the documents 3 days in advance,contacted the Turkish agent to resend the certificate immediately after finding the problem,and the second declaration was completed in only 1 day.The subsequent commodity inspection sampling was also communicated in advance,and the total duration was 5 days shorter than the first attempt.

Zhongshen’s services cover the whole process from document pre-review to commodity inspection release.In response to the unique requirements of stone import,the team will communicate with the port commodity inspection department in advance to confirm the sampling ratio and testing standards,so as to avoid losses caused by information asymmetry for enterprises.

## Disassembly of Core Procedures for Stone Import Customs Declaration

### 1.Document Pre-review Stage: Avoid Compliance Risks in Advance

Document pre-review for stone import is the first "checkpoint",and the unique compliance requirements include:

- The certificate of origin shall be issued by the official agency of the exporting country,and must mark the longitude and latitude of the stone mining site (new requirement in 2026)
- The radioactivity test report shall comply with the GB6566-2010 standard,and the testing institution shall have both CNAS and CMA qualifications
- The packing list shall mark the specification,weight and unique number of each stone to facilitate the matching of commodity inspection sampling
- If the stone is used for interior decoration,an additional *Declaration on Use of Stone for Interior Decoration* shall be provided

Supervisor Zhuang of Zhongshen is responsible for document pre-review.She will receive the first draft of the customer’s documents 3 days before the goods arrive at the port,and check every detail one by one.Last year,a building material trader’s radioactivity test report only had CNAS qualification without CMA seal.Supervisor Zhuang immediately contacted the customer to resend the report with dual qualifications,avoiding secondary testing by the port commodity inspection authority.

### 2.Port Customs Declaration Stage: Accurately Match Tariff Rate and Origin

During port customs declaration,the unique requirements for stone are concentrated in tariff rate declaration and commodity inspection pre-declaration:

- Stone is a commodity subject to statutory inspection,and a *Commodity Inspection Pre-declaration Form* shall be submitted at the same time of declaration,otherwise it cannot be released
- Tariff rates vary by origin: stone from Italy enjoys a 3% MFN tariff rate,while stone from Turkey is subject to a 4% rate,so the origin shall be declared accurately
- The customs declaration form shall mark the HS code of the stone (2515120090 for marble,2516110090 for granite),and incorrect code will lead to wrong application of tariff rate

Ms.Jiang is in charge of the customs declaration post.She will pre-enter the data in the Single Window in advance to check whether the tariff rate matches the certificate of origin.Last year,a customer mistakenly declared Turkish stone as Italian stone,and Ms.Jiang corrected it in time after discovering the error,helping the customer save RMB 12,000 in tariffs.In addition,Zhongshen will submit the commodity inspection pre-declaration form simultaneously to avoid disconnection between customs declaration and commodity inspection procedures.

### 3.Commodity Inspection and Quarantine Stage: Quickly Handle Testing Issues

Commodity inspection and quarantine is a key link in stone import,and the unique quarantine requirements include:

- On-site sampling is required for radioactivity testing,with a sampling ratio of no less than 10%,and sampling points shall cover different batches
- It is necessary to test whether the stone contains harmful impurities such as asbestos,lead and mercury,and goods exceeding the standard shall be returned or destroyed
- If the sampling is unqualified,a qualified test report of the same batch shall be submitted within 7 days,otherwise the goods will be detained

Manager Gao will communicate with the commodity inspection department in advance to confirm the sampling location and time,so as to avoid goods滞留 at the port.Last year,a customer’s calacatta marble radioactivity test exceeded the standard by 0.2Bq/g.Supervisor Zhuang immediately contacted the customer to provide a qualified test report of the same batch,and assisted the customer to re-sample,and finally passed the commodity inspection smoothly,avoiding the return of goods (the return cost is about RMB 50,000).

## Value Comparison of Stone Import Agency Services

To show the value of the agency more intuitively,we compared the process data of self-handled import and Zhongshen agency services:

| Process | Average Duration for Self-handled Import | Average Duration for Zhongshen Agency Service | Cost Difference Per Shipment |
| --- | --- | --- | --- |
| Document pre-review | 3-5 days | 1-2 days | Labor cost saved: RMB 2,000 |
| Port customs declaration | 2-3 days | 1 day | Avoidance of document rejection loss: RMB 5,000 |
| Commodity inspection and quarantine | 3-4 days | 2 days | Avoidance of unqualified sampling loss: RMB 30,000 |
| Total duration | 8-12 days | 4-5 days | Total saved/avoided loss: over RMB 37,000 |

## Summary: Core Value of Professional Agencies

Zhongshen has specialized in stone import agency for over 20 years,is familiar with the compliance requirements of major origins such as Italy and Turkey,and can help customers avoid risks such as discrepant documents and unqualified commodity inspection in advance.Among the more than 120 stone import enterprises we cooperated with last year,none was returned or fined due to compliance issues,and the average customs clearance time was reduced by more than 40%.

Manager Gao stated that the core of stone import is "front-loaded compliance".Enterprises handling it on their own are prone to losses due to information asymmetry,while professional agencies can turn years of experience into efficient services to help customers save time and reduce risks.For example,in March this year,a building material trader in Shanghai imported a batch of statuario marble from Italy.Zhongshen completed the customs clearance in only 4 days,2 days earlier than the customer’s expectation,avoiding storage fees and project delay losses.
