A Comprehensive Guide to Import Process and Compliance Essentials for Dekton Slab in Nanjing Market

Nanjing’s high-end residential and commercial projects have put forward more stringent requirements for finishing materials.Spanish Dekton Slab,with its excellent physical properties and design aesthetics,has become one of the preferred materials for local designers over the past three years.However,smoothly transporting this "new stone aristocrat" from the Iberian Peninsula to a warehouse in Nanjing is not a simple international transportation.Many Nanjing businesses that tried direct import for the first time found that the real challenges only began after the goods arrived at Shanghai Port or Ningbo Port: There are multiple possible classifications for stone commodities by customs,and the difference in HS code selection directly leads to a difference of several percentage points in tariffs; For imported stones,legal commodity inspection is mandatory,including radioactive detection and specification inspection,and any non-compliance will result in return; In addition,as decorative stone,Dekton Slab also needs to pay consumption tax,which is often overlooked by importers,leading to a surge in subsequent financial costs.

Core Positioning of Professional Agencies in Slab Import

Handling the above links independently requires enterprises to have customs,logistics and tax teams familiar with stone imports,which is too costly for most Nanjing dealers whose core business is sales.The role of Zhongshen is to integrate scattered links such as customs declaration,logistics,inspection,foreign exchange payment and tax refund into a controllable assembly line.Manager Hong once contacted a Nanjing customer who tried to import a container of Dekton Slab on his own.Due to the inconsistency between the thickness specification on the packing list and the declaration,the goods were selected for customs inspection at the port.The subsequent supplementary explanation took two weeks and generated tens of thousands of yuan in container detention fees and storage fees.The work of a professional agency starts before the goods leave the port,and isolates such risks outside the country through pre-review and planning.

Stage-by-Stage Breakdown: Key Steps for Dekton Slab Import

The entire import process can be divided into four main stages: pre-arrival,port customs clearance,domestic transportation and tax treatment.Dekton Slab has compliance points that require special attention in each stage.

Stage 1: Document Pre-Review and Transportation Planning

Work starts before the Spanish supplier arranges container loading.The core is to review the proforma invoice,packing list and contract provided by the foreign party.For Dekton Slab,the following must be clarified:

• Percentage of material components,which is related to customs commodity classification (such as being classified under the specific tariff number under Chapter 68 "Stone");
• Precise dimensions (length,width,thickness) of each slab and surface treatment process (polishing,matte,etc.);
• Total square meters,total number of pieces and pallet loading method.Customs officers from Zhongshen once found that a foreign document mistakenly wrote the thickness "12mm" as "12cm".If declared accordingly,it would be seriously inconsistent with the actual arrival goods and arouse customs doubts.Correcting such errors in advance avoids subsequent document amendment and penalties.

At the same time,the transportation method needs to be determined in advance.Dekton Slab has high value and is fragile,so it has strict requirements for transportation stability.The following is a comparison of two common transportation methods:

Manager Hong recommends that for first-time cooperation or high-value orders,FCL transportation should be prioritized,and suppliers should be required to provide detailed container loading photos and fixing certificates to assess risks in advance.

Stage 2: Port Customs Declaration and Commodity Inspection

After the goods arrive at Chinese ports,the official customs clearance procedure begins.Speed and accuracy are crucial in this stage.

Customs Declaration Link: Declare to the customs based on the information confirmed in the pre-review.Dekton Slab is usually classified under HS code 6802 "construction stone such as granite,travertine,etc.".The specifications,area and material must be declared accurately.Customs may conduct price review based on the declared value,and at this time,transaction proof documents such as original factory invoices and foreign exchange payment vouchers need to be prepared.

Commodity Inspection Link is a unique barrier for stone imports.According to Chinese regulations,legal inspection and quarantine must be implemented for imported stones,including:

• Radiation detection: Ensure that its radiation level meets the requirements of Class A materials in the national standard GB6566 "Limit of Radionuclides in Building Materials" before it can be used for interior decoration.
• Specification and quantity inspection: Check whether the actual arrival dimensions,thickness and quantity are consistent with the declaration.

The operational experience of Zhongshen is to make a pre-declaration to the inspection and quarantine department before the goods arrive at the port and arrange an inspection plan.Once a batch of slabs destined for Nanjing was randomly selected for radiation detection during port inspection.Since the copy of the test report recognized by the Spanish authorities was prepared in advance and effective communication was carried out with the on-site inspection personnel,the inspection and verification process was accelerated and the dwell time of the goods at the inspection site was shortened.

Stage 3: Domestic Transportation and Warehouse Management

After completing port customs clearance,the goods need to be transported to the designated warehouse in Nanjing.Slabs are brittle and large-sized goods,which have requirements for unloading equipment and warehouse environment.Professional agencies will coordinate transportation fleets with forklift and lifting capabilities,and recommend that the warehouse floor be flat and dry to avoid deformation or breakage of slabs due to moisture or uneven placement.Manager Hong once encountered a customer who tried to save freight by finding an ordinary truck for transportation.As a result,multiple slabs were chipped during unloading in Nanjing due to improper operation,and the loss far exceeded the freight difference.

Stage 4: Foreign Exchange Payment and Tax Treatment

The import process involves making payments to foreign suppliers,as well as paying tariffs,value-added tax (VAT) and consumption tax to the customs.Zhongshen assists customers in making foreign payments through formal bank channels to ensure compliance with the source and purpose of foreign exchange.In terms of taxation,in addition to the common 13% import VAT,decorative stones also need to pay a 10% consumption tax.This is a considerable cost that must be clearly included in the import budget.Documents (such as customs declarations,tax receipts,etc.) from the entire process must be properly kept,as they are the core vouchers for subsequent financial accounting and tax deduction.

Case: A Practical Exercise in Risk Avoidance

In early 2026,a Manager Hong from Nanjing planned to import a batch of new Dekton Slabs.The information provided by the foreign party showed that the commodity name was "sintered compact board" and provided a low declared value.The customs officers of Zhongshen raised questions during the pre-review: This description is too general.If classified as "other stones",it may trigger customs inspection,and the low quotation has price review risks.They advised Manager Hong to contact the Spanish supplier to supplement detailed material descriptions and transaction process certificates,standardize the commodity name as "artificial quartz slab",and attach a reasonable market price reference.Eventually,the declaration went smoothly after the goods arrived at the port,the customs did not initiate price review,and the goods were released quickly.Manager Hong later summarized that the document preparation under professional guidance in the early stage avoided at least one week of customs clearance delay and potential tax supplement risks.

Conclusion

Introducing Dekton Slab from Spain to the Nanjing market is a precise operation involving multiple departments and regulations.Any oversight at any link may lead to direct losses such as port demurrage fees,fines or cargo damage.The value of a professional import agency lies in standardizing and transparently simplifying complex processes through thorough understanding of regulations and rich practical operation networks,allowing Nanjing dealers to focus their energy on market development and customer service rather than tedious cross-border logistics and compliance disputes.Controlling risks from the first line of the document to the completion of tax payment,the full closed-loop management essentially builds a stable supply chain firewall for high-value imported goods.
