Shanghai Port import of high-end quartz stone, professional agent providing full-process compliant customs clearance services

Core Pain Points and Compliance Logic of Quartz Stone Import Agency

Many building material merchants I have contacted have suffered losses when importing high-end quartz stone: either wrong HS code classification leads to requirement to pay high additional tariffs during valuation,or incomplete commodity inspection data results in goods being detained for more than 10 days,and some others miss tax reduction benefits because the certificate of origin does not comply with RCEP rules.The core of these problems is the lack of familiarity with the latest 2026 import regulatory rules - especially the inspection standards for high-end building materials at Shanghai Port are about 30% stricter than those for ordinary general cargo,and any slight oversight will trigger cascading risks.

Compliance Requirements for Accurate HS Code Classification

The HS code range for high-end quartz stone is 68101910-68101990,but classification differences caused by different specifications (such as thickness,density) and whether there is a decorative layer directly affect the tariff rate.In 2026,China Customs added "material composition proportion" as a classification basis.For example,high-end quartz stone with quartz content exceeding 93% is classified as first-class high-end quartz stone,which needs to be declared separately during classification.I once assisted a building material merchant in correcting a classification error: the original agency classified high-end stone with 95% quartz content into the general category,and was required to pay an additional 18% tariff during valuation.After reclassification,the tax rate was adjusted to 10%,saving nearly 200,000 yuan in costs.

Risk Prevention and Control of Customs Valuation and Anti-Dumping Duties

In 2026,although the EU’s anti-dumping duties on Chinese high-end building materials do not directly cover quartz stone,Shanghai Port will adopt the "transaction value of identical or similar goods" model for valuation of high-end quartz stone originating in Italy and Spain.If the declared price is lower than the customs benchmark price,a price verification will be triggered,and a full set of documents including purchase contracts,payment vouchers and original manufacturer invoices shall be provided.Once a Ms.Hu’s goods were required to provide a third-party price assessment report because the declared price was 8% lower than the benchmark price.We prepared the original manufacturer’s quotation and bulk purchase agreement in advance,successfully passed the customs valuation,and incurred no additional taxes and fees.

Pre-inspection of Commodity Inspection and Advance Preparation of Certificate of Origin

For commodity inspection of high-end quartz stone,"material test report","specification manual" and "environmental protection certification" are required.In 2026,the requirement for "radioactive substance test" is added.It is necessary to communicate with overseas suppliers in advance to ensure that the documents meet the format standards of Shanghai commodity inspection.In addition,the electronic authentication requirement for RCEP certificate of origin has been fully implemented.If a paper certificate is submitted,it will be deemed invalid and cannot enjoy tax reduction benefits.I will remind clients to prepare the electronic version of the certificate of origin 10 days before the goods are shipped,and check every item (such as HS code,cargo value,exporting country) to avoid tax reduction failure caused by inconsistent documents.

Practical Cases of Quartz Stone Import Agency

A building material merchant imported 120 tons of high-end quartz stone from Italy.Due to the chaotic process of the original agency,it was found after the goods arrived at the port that the certificate of origin was in paper version and the HS code classification was wrong,resulting in demurrage fee of 2000 yuan per day,with extremely high risk of cargo detention.After we took over the case,we first reclassified the HS code and supplemented the test report of quartz content; then we coordinated with the overseas supplier to apply for the electronic certificate of origin,and expedited the RCEP electronic authentication; finally we communicated with Shanghai commodity inspection in advance to arrange priority inspection.The whole process took 7 days,the goods were successfully cleared,demurrage fees of more than 14,000 yuan were avoided,and a 5% tariff reduction was enjoyed at the same time.
