I am a new practitioner in the stone import trade. Earlier this month, I booked two containers of marble from Turkey, which will arrive at Shanghai Port next week. Previously, I only asked friends to help handle small shipments. This time the cargo volume is relatively large, so I do not want to trouble my friends anymore, and plan to find a professional customs clearance agency on my own.
But I have no idea how the stone import customs clearance agency process works at all, and what I need to cooperate to prepare in advance. I heard from peers that a batch of stone was detained last month due to excessive radiation, and another importer faced half a month of port detention due to incorrect product name on documents, resulting in tens of thousands of yuan of container detention charges.
I am very worried about encountering problems now. I hope to complete customs clearance quickly and deliver the goods to the factory, while avoiding being inspected due to non-compliance. I want to ask about the specific operation procedures and core key points that need attention.

First of all，conduct pre-audit of document details. You need to provide bill of lading，commercial invoice，packing list，trade contract，certificate of origin and stone radioactivity test report in advance. Radioactivity test report is the core document for stone import customs clearance，which must be issued by a customs-recognized third-party institution and is absolutely indispensable. We will check in advance whether the product name，weight and origin information on the documents are consistent with the actual information of the goods，so as to avoid abnormal price verification or cargo seizure caused by inconsistent documents.
The connection of core nodes is divided into three fixed steps. The first is pre-declaration before cargo arrival. In 2026，customs authorities across China support pre-arrival import declaration. Completing information entry in advance can shorten the customs clearance time after arrival by at least 2 working days. The second is document exchange after cargo arrival. We will coordinate with the shipping company to complete document exchange in advance，and arrange tax payment after confirming all information is correct. The third is to cooperate with customs inspection. If all documents are correct，inspection and release can be completed within 3 working days.
In terms of abnormal response plans，we have mature solutions for the two most common anomalies，namely unqualified radioactivity test results and price verification disputes. If the radioactivity test result is unqualified，we will arrange return shipment immediately，which will not generate additional long-term port detention fees. If a price verification dispute occurs，we will sort out the port transaction price data of similar stones in advance，assist the customs to re-verify the price，and quickly complete the review process.
For final compliant implementation，after cargo release，we will directly arrange trailers to deliver the goods to the designated factory. The full set of customs clearance documents will be sorted out，archived and delivered afterwards. You only need to cooperate to provide basic information throughout the whole process，no need to follow up on complicated procedures.

Stone import price verification is the core risk point in the customs declaration process. The customs will refer to the concurrent port transaction prices of stones of the same category from the same origin to verify the price. If the declared price deviates too much from the normal interval, it will directly trigger the price verification process, requiring supplementary materials such as foreign exchange payment vouchers, original manufacturer invoices, and transaction negotiation records. If the required supporting materials cannot be provided, the customs will levy taxes directly according to the system default price, which will greatly increase the import cost.
For price verification disputes, you can sort out the transaction data of similar stones at the same port in the past three months in advance, provide complete cargo ownership certificates and foreign exchange payment slips, and assist the customs to complete price verification. Under the customs clearance integration mode, the price verification result is valid nationwide and will not affect the secondary circulation. If there is a situation of document push or document deletion, we can complete document deletion and re-declaration within 1 working day, adjust the declaration information, and avoid port detention.

Stone belongs to heavy cargo, and additional container detention fees and storage fees are easily generated in the import logistics link. It is necessary to apply to the shipping company in advance to extend the free storage period and free container period. Generally, 7-10 days of free container period can be obtained, which is long enough to complete the customs clearance process and avoid high overdue fees. In case of overbooking and cargo rolling, or need to change the port of call, we can link up port resources across the country in advance, adjust the docking port, and will not delay the delivery of goods.
For stone import, you can choose direct sailing or transshipment scheme according to the cargo volume. Full container cargo gives priority to direct sailing, and LCL cargo can choose transshipment scheme to share the cost. The bill of lading needs to check the cargo ownership information in advance, complete the endorsement transfer operation in advance if necessary, and avoid cargo ownership disputes.

Stone import can enjoy partial bilateral agreement tax rates. It is necessary to provide qualified certificate of origin, complete the pre-review of origin in advance, confirm the applicable tax rate preferences, and reduce the import tax cost. If you import stones from agreement member states, you can apply for VAT deferral, and do not need to pay value-added tax in advance during the customs clearance process, which relieves the pressure of capital occupation and optimizes cash flow.
For stone import involving cross-border related transactions, it is necessary to make transaction pricing in advance, comply with the arm's length principle, avoid triggering transfer pricing investigation, complete risk isolation of base erosion in advance, and also complete the declaration and accrual of withholding income tax involving non-resident enterprises in advance, so as to avoid compliance risks.

The receipt and payment of foreign exchange for stone import must comply with foreign exchange regulatory requirements. In 2026, you can choose CIPS cross-border RMB payment to avoid exchange difference losses caused by exchange rate fluctuations, which has faster arrival speed and lower handling fee than traditional SWIFT settlement. If you use an offshore account for receipt and payment, you need to declare the income and expenditure information in advance, keep the corresponding transaction documents, cooperate with regulatory verification, and avoid abnormalities in foreign exchange settlement and bookkeeping.
SWIFT messages need to check the transaction information in advance to ensure that the product name and amount are consistent with the declaration information, so as to avoid the failure of foreign exchange collection caused by wrong message information. You can choose the low point of exchange rate to complete foreign exchange purchase, so as to optimize the foreign exchange purchase cost.

In stone import trade, it is necessary to clarify the division of responsibilities in the contract in advance. For situations such as unqualified radioactivity test and cargo damage, clarify the seller's responsibility for bearing return freight, so as to avoid being unable to recover compensation after problems occur. For L/C payment, it is necessary to check soft clauses in advance, such as clauses that require the presentation of quality certificate issued by the consignee to negotiate payment, which need to be modified in time to avoid being unable to negotiate payment after shipment.
If it is necessary to transfer cargo ownership, you can complete cargo release with a letter of guarantee, review the terms of the letter of guarantee in advance, clarify the effective and invalid conditions of the letter of guarantee, and avoid cargo ownership loss caused by invalid letter of guarantee. For branded stones, it is necessary to complete IPR customs record filing in advance.

Customs inspection for stone import mainly focuses on three directions: radioactivity test, product name classification and cargo value verification. Check the authenticity of the container seal in advance, confirm that the seal number is consistent with the bill of lading information, and avoid the problem of cargo tampering.
For machine inspection, sort out the packing details of the goods in advance, mark the position of each stone, which is convenient for machine inspection imaging verification, and will not generate additional costs due to secondary unpacking. If it is necessary to send samples for identification, cooperate with the customs to take samples in advance, follow up the progress of the laboratory test report, give feedback and adjustment immediately when problems are found, avoid prolonging the inspection time due to wrong report, interpret the inspection notice in advance, clarify the inspection requirements, and prepare corresponding documents to arrive at the site in advance for cooperation.

Stone belongs to hard heavy cargo. The transport package needs to be moisture-proof and reinforced to avoid collision and damage of stones caused by package damage during transportation. The container is prone to get damp during sea transportation, so it is necessary to place desiccant in the container to complete moisture-proof protection on the stone surface, so as to avoid water absorption and discoloration of marble stones that affect the quality.
Stone packaging does not need to comply with dangerous goods packaging standards, but for stones for special purposes, it is necessary to compile MSDS documents in advance, clarify the composition and radiation parameters of the stones, and cooperate with customs verification. High-density hard paper lining is selected as the buffer packaging material to avoid wear of stone edges and corners that affect sales.

You can adjust the supply chain structure according to the order volume for stone import. For long-term stable import, you can sign an annual contract with the shipping company to get more favorable ocean freight prices and reduce the overall logistics cost. In terms of Incoterms selection, when the buyer is responsible for logistics and customs clearance, choosing FOB term allows you to control logistics and customs clearance costs by yourself and avoid price markup by the seller.
When the seller needs to be responsible for the whole process, choose CIF term, and check the customs clearance qualification of the seller in advance to avoid problems in customs clearance. You can adjust the arrival time in combination with domestic inventory to realize inventory linkage, avoid overstock or stockout, accurately calculate the total customs clearance and logistics cost of each container of stones, and optimize the cost expenditure of each link.
