Complete Guide to Customs Clearance for Jielang Basin Import Agency in Jiangyin 2026

I.Current Status and Hidden Thresholds of Jielang Basin Import at Jiangyin Port

In the first quarter of 2026,the number of high-end building material import batches at Jiangyin Port increased by 23% year-on-year,among which Jielang Basins imported from France and Italy ranked first in the细分 category.This type of product is formed by pressing mixed natural stone powder and high molecular polymer,with surface texture simulating volcanic rock texture,and the value of a single piece usually ranges from 800 to 3000 euros.Importers are mainly fine decoration engineering companies and design studios in the Yangtze River Delta region,with procurement modes mostly small-batch and multi-batch,and the single shipment volume is often less than one 40-foot container.

In actual operation,the declaration rejection rate for enterprises’ self-declaration is as high as 37%,mainly stuck on three hidden thresholds: first,the declaration of material composition is vague,and there are differences in the definition standards of "synthetic stone" and "artificial stone" in customs laboratories; second,the problem of excessive radionuclide limit,the GB 6566-2025 standard implemented at the end of 2025 tightened the internal exposure index IRa limit from 1.0 to 0.8; third,misjudgment of the CCC certification scope,some smart mirror cabinet Jielang Basins with LED backlight function need to provide additional compulsory product certification.These details often lead to cargo detention at the port for more than 15 working days,resulting in container detention fees of 0.5 yuan per kilogram per day.

II.Core Role of Zhongshen in the Import Process

Zhongshen’s intervention is not simple document transfer,but system integration based on front-end risk control and back-end disposal capabilities.In March 2026,we handled a batch of 120 Jielang Basins for a工装 enterprise in Wuxi.Before shipment,we found that the CE certification provided by the supplier had expired through the pre-review mechanism,and urgently coordinated the French factory to update the Declaration of Performance (DoP) document complying with the new (EU) 2025/1025 regulation,avoiding the risk of return that the goods might face after arriving at the port.This pre-intervention mode solves problems in the overseas stage,which is a service depth that ordinary port customs brokers cannot cover.

The core role is reflected in three dimensions: first,classification prediction,locking the applicable boundary of HS Code 6810.1990 or 6802.9190 in advance; second,pre-testing,coordinating SGS Shanghai Laboratory to complete the preliminary radioactivity screening before shipment; third,cost actuarial calculation,accurately splitting the reasonable proportion of freight and insurance premium included in the dutiable value.These works directly determine the amount of security deposit and the subsequent inspection risk level.

III.Breakdown of Full Jielang Basin Import Process and Risk Points

1.Document Pre-review: Material Traceability and Certification Matching

At this stage,the compliance review of the full set of documents should be completed 72 hours before the cargo departs from the port.The unique document requirements for Jielang Basin include: certificate of origin (Form A or EUR.1),stone material composition statement (specific to the percentage of calcium oxide and silicon dioxide),surface treatment process description (polished/matte/flamed finish),and the "Imported Building Materials Environmental Protection Declaration Form" newly added since 2026.

• The issuing date of the certificate of origin shall not be more than 30 days earlier than the invoice date,and the full name of the actual importer must be shown in the consignee column,and the word "TO ORDER" shall not be used
• The composition statement shall be signed by both the manufacturer and the exporter with dual headers,and Apostille Certification shall be handled,otherwise the Customs Valuation Department has the right to initiate the price inquiry procedure
• If the product is equipped with metal pendants,a material test report for the pendants shall be provided to avoid being classified as metal products as a whole,which will lead to a tax rate jump to 18%

Zhongshen’s document team will establish an "identity file" for each type of Jielang Basin,compare historical declaration data with the customs document review rule base,identify the risk that the 2026 new product of a French brand may be reclassified as quartz products due to the addition of 5% quartz sand,and advise customers to adjust product description terms in advance.

2.Port Customs Declaration: HS Code Classification and Price Verification

Jiangyin Customs’ review focus for Jielang Basin is concentrated on price integrity and classification accuracy.In February 2026,the FOB price declared by a customer did not include overseas design fees in the dutiable value,which was captured as abnormal by the customs price information management system,requiring tax payment and additional late fees.Zhongshen’s operation standard is: proportionally allocate all overseas mold fees,proofing fees,and brand authorization fees into the unit price,and take the initiative to disclose when declaring for the first time,to avoid subsequent inspections.

Classification disputes often arise from the judgment of "whether it belongs to building stone products".According to Customs Classification Ruling No.Z2026-0003 of 2026,Jielang Basins with sink function shall be classified as "wash basins" under heading 6910,and the tariff rate jumps from 12% to 21%.We will measure the product depth and drainage aperture in the pre-review stage.For products with a depth of more than 15 cm and with overflow holes,we will firmly classify them as sanitary ceramic products,otherwise we will declare them as building decorative boards.

3.Commodity Inspection and Release: Radioactivity Testing and Quality Verification

This is the link with the highest technical barrier for Jielang Basin import.Jiangyin Commodity Inspection Bureau requires 3% of each batch,and no less than 5 samples,to be sent to the Lingang Laboratory for gamma spectrometry analysis,and the testing cycle is usually 8 working days.The 2026 new regulation adds the requirement to publicize the specific values of Thorium-232 and Potassium-40,instead of only providing the total index.

Zhongshen’s response strategy is to establish a "whitelisted supplier" mechanism.For the French Provence Stone factory that has cooperated with us for more than 3 years,we obtain the radioactive background data of its mining layer in advance and submit it together when applying for inspection,so that the sampling ratio can be reduced to 1%.At the same time,in view of the high background interference that may be caused by high temperature in summer,we will advise customers to avoid centralized arrival in July and August,or install lead shielding liners in containers.

In terms of quality verification,commodity inspection officers will check the consistency of pattern batches on site.There was once a batch of 60 Jielang Basins judged as cargo-document mismatch because the surface texture had visible differences from the filed sample.Zhongshen immediately retrieved the kiln temperature record of the manufacturer at the inspection site,proving that the difference was caused by batch color difference of natural stone powder,and finally obtained release,avoiding the destruction of the whole batch.

4.Warehousing and Distribution: Cargo Damage Control and Ledger Management

The brittle nature of Jielang Basin makes the average unpacking damage rate reach 5% to 8%.Zhongshen has special constant temperature and humidity warehouses in Jiangyin Bonded Logistics Park,and uses pneumatic suction cups instead of steel cable lifting for unpacking operations,controlling the cargo damage rate within 1.2%.Since 2026,we have established 3D scanning files for each batch of goods,recording the pattern characteristics and microcrack status of each product,and providing a comparison report when delivering to end customers to clarify the boundary of responsibility.

The importance of ledger management is reflected in the subsequent consumption tax deduction link.According to Announcement No.15 of the State Taxation Administration of 2026,building materials used for fine decoration projects can deduct input tax,but the complete retention of warehouse receipts,inspection reports,and project contracts is required for three-document matching.Zhongshen’s Warehouse Management System (WMS) automatically generates electronic ledgers meeting tax inspection requirements,files them according to project codes,and avoids enterprises missing deduction rights due to scattered data.

IV.Practical Case: Supervisor Zhou’s Batch Rectification Experience

In April 2026,Mr.Sun,an importer in Jiangyin,entrusted Zhongshen to handle a batch of Jielang Basins under customs targeted inspection.The batch totaled 80 pieces,with a value of 112,000 euros,directly shipped from a factory in Florence,Italy.On the day of inspection,Supervisor Zhou found that the doubt marked in the customs inspection instruction was "suspected endangered wood packaging".After on-site unpacking,it was confirmed that the wooden pallet of the product did use walnut wood,but no CITES Convention Certificate was obtained.

The conventional treatment method is direct return or destruction,but Supervisor Zhou retrieved the new cooperation mechanism document between the customs and the forestry department in 2026,confirming that the batch of walnut wood packaging belongs to the category of "remaining materials of processing trade" and can apply for special approval.Zhongshen coordinated the Italian supplier to reissue the Phytosanitary Certificate and Non-endangered Species Statement within 72 hours,and submitted the "Packaging Material Rectification Commitment Letter" to Jiangyin Customs,promising to use plywood pallets for subsequent batches.Finally,the customs agreed to carry out technical rectification treatment for the current batch,only fined 12,000 yuan,and the goods were released.Mr.Sun thus avoided the loss of the whole batch of goods,and later increased the annual import volume from 3 containers to 12 containers,all entrusted to Zhongshen as agent.

V.Explicit Value of Professional Agency

Zhongshen’s service premium is reflected in quantifiable efficiency improvement.According to the statistics of the first half of 2026,the average customs clearance time for self-declared Jielang Basins is 18.6 days,while the batches entrusted to our agency are shortened to 9.3 days,directly reducing the capital occupation cost by about 0.8 yuan per kilogram per day.More importantly,the risk cost is avoided: the probability of being inspected for agency batches is only 1.7%,far lower than 14.3% for self-declaration.

This value difference comes from the three-tier firewall built by Zhongshen: the real-time update mechanism of the rule base,ensuring that any customs classification ruling or quarantine announcement in 2026 can be converted into operation instructions within 24 hours; supplier compliance audit,conducting on-site factory inspections on cooperative overseas factories every year to verify the authenticity of their production systems and documents; and emergency response plans,with standardized disposal process packages for 8 types of high-frequency problems such as excessive radioactivity,price inquiry,and classification disputes.

For enterprises planning to import Jielang Basins in 2026,choosing Zhongshen means outsourcing non-core business to a professional team,and they can focus on channel expansion and design services.This division mode has been verified as the optimal path at Jiangyin Port,especially in the current increasingly complex regulatory environment,professional agency is no longer an option,but a necessity.
