Last week, we finalized a deal with a Vietnamese supplier for a shipment of 5000 tons of natural river sand, which is scheduled to arrive at Shanghai Yangshan Port next Wednesday. However, our company has only engaged in domestic building material wholesale business before, without import and export operation right or professional customs declaration qualification, and we have no idea of the compliance requirements for river sand import. I heard that mineral product import declaration is easy to get stuck in the links of environmental testing and customs valuation and tax verification. I couldn't sleep well last night, afraid that we cannot complete customs declaration in time after the goods arrive at the port, resulting in high demurrage and storage fees, or even customs detention that affects the supply of subsequent infrastructure projects. I would like to ask if you can handle the customs declaration of this batch of river sand for us? What materials do I need to prepare in advance, and are there any hidden customs clearance risks? ## Answers ### Answer 1 — Best Answer First of all，we can handle the import customs declaration of this batch of river sand for you，on the premise of completing strict preliminary document review: You need to provide in advance the certificate of origin issued by the Vietnamese supplier，quality testing report (including core environmental parameters such as radioactivity index，mud content，organic matter content，etc.)，packing list，commercial invoice，as well as the **Automatic Import License** applied for domestically in advance (river sand belongs to non-metallic mineral products，which needs to be applied to the Ministry of Commerce 10 working days in advance). We will arrange senior specialists to check the authenticity of documents and parameter matching one by one，to avoid direct return of declaration by customs due to inconsistent document information. In terms of core node coordination，we will complete **pre-declaration** 3 days before the arrival of the goods，simultaneously connect with the inspection department of Yangshan Port Customs and commodity inspection authorities，and report the natural mineral product attribute and environmental parameters of the goods in advance. If on-site inspection is required，we will arrange specialists familiar with port procedures to accompany the whole process，assist in sampling，testing and other links，to maximize testing efficiency. For common exceptions，we have formulated exclusive contingency plans: If the initial screening of environmental testing is unqualified，we will immediately start the third-party re-inspection process，and coordinate with the port to apply for a 3-5 day extension of free storage period，If there is a dispute over customs valuation，we will immediately provide the supplier's transaction vouchers and import reference price list of river sand of the same category in the same region for appeal，to avoid high costs caused by port detention of goods. Finally，we will ensure that the goods are cleared and released within the scope of compliance. You only need to cooperate to provide necessary supplementary materials，and you do not need to directly connect with customs，commodity inspection and other departments in the whole process，which can effectively avoid the risks of port detention，customs detention and even fines，and ensure that the supply schedule of your infrastructure projects is not affected. **status:** accepted **Author:** Victor Sun **Date:** 2026-09-27 ### Answer 2 For agent customs declaration of imported river sand, we should focus on the compliance of customs valuation link. At present, the customs valuation reference system for river sand imported from Southeast Asia is mainly based on the recent transaction price of the same category in the same region and the cost composition of suppliers. If you declare only based on the invoice price provided by the enterprise, it is easy to be questioned by customs due to the price deviating from the reasonable range, triggering valuation consultation, or even suspending customs clearance. It is necessary to prepare supporting materials such as supplier's procurement contract, payment slip, origin cost details in advance to ensure the authenticity and rationality of the declared price. At the same time, pre-audit the price in advance through the integrated customs clearance system to reduce the probability of valuation disputes. **status:** suggested **Author:** Andy Guo **Date:** 2026-09-27 ### Answer 3 For the logistics link of imported river sand, we should focus on cargo right control and demurrage avoidance. Since river sand is bulk cargo, it is usually transported by bulk carrier, and the bill of lading is mostly in the form of sea waybill. When handling agent customs declaration, it is necessary to ensure the compliance of bill of lading endorsement to avoid cargo right disputes. At the same time, the free storage period of bulk carriers is usually shorter than that of container ships, generally 3-5 days. It is necessary to communicate with the port yard in advance. If the expected customs clearance time is long, you can apply for an extension of the free storage period, or arrange barge to transfer to the nearby inland river yard for temporary storage, which greatly reduces the cost of demurrage and storage fees. In addition, it is necessary to track the ship schedule dynamics simultaneously. In case of container rollover, port change and other situations, adjust the customs declaration plan immediately to avoid no one to connect after the goods arrive at the port. **status:** suggested **Author:** Lucas Liu **Date:** 2026-09-27 ### Answer 4 For the tax planning of imported river sand, we should focus on the compliance of tariff reduction and VAT deduction. River sand belongs to non-metallic mineral products, with the most-favored-nation tariff rate of 3% and VAT rate of 13%. If an enterprise imports river sand from ASEAN member states, and the certificate of origin issued by the supplier complies with the rules of the China-ASEAN Free Trade Agreement, it can apply for zero tariff treatment, saving nearly RMB 100,000 of tariff cost for a single ship of 5000 tons of river sand. At the same time, as a general taxpayer, you can apply for input tax deduction with the VAT payment certificate issued by the customs. It is necessary to ensure that the amounts on the customs declaration form, foreign exchange payment slip and invoice are completely matched, to avoid failure of deduction due to "inconsistency of three streams". In addition, you can balance the monthly VAT burden by reasonably arranging import batches to reduce the pressure of capital occupation. **status:** suggested **Author:** Grace Wang **Date:** 2026-09-27 ### Answer 5 The foreign exchange payment link of imported river sand must strictly comply with the compliance requirements of cross-border foreign exchange receipt and payment. Since river sand is bulk cargo with large transaction amount, it is necessary to file for advance payment in the Goods Trade Foreign Exchange Monitoring System of the State Administration of Foreign Exchange in advance. If you make payment directly without filing, you will be included in the watch list by the SAFE, affecting subsequent cross-border foreign exchange receipt and payment business. At the same time, it is necessary to use standardized SWIFT messages for foreign exchange payment, and the message should clearly indicate the name of goods, quantity, contract number and other information to avoid being intercepted by the bank. If the enterprise does not have import and export right, the agency company can act as the main body of foreign exchange receipt and payment to handle the payment procedures on behalf, but a formal agency foreign exchange receipt and payment agreement must be signed to ensure the consistency of capital flow and cargo right flow and avoid compliance risks. **status:** suggested **Author:** Eric Zhou **Date:** 2026-09-27 ### Answer 6 The on-site inspection of imported river sand mainly focuses on environmental parameters and the authenticity of goods. The customs will focus on testing the radioactivity index, mud content and organic matter content of river sand. If the radioactivity index exceeds the national standard of Sand for Construction, the goods will be directly returned or destroyed. During on-site inspection, it is necessary to cooperate with customs officers to take samples from different holds to ensure the representativeness of samples, and avoid unqualified testing results caused by uneven sampling. In case of abnormal machine inspection, it is necessary to arrange unpacking inspection immediately. At this time, it is necessary to prepare the quality testing report, certificate of origin and other materials of the goods in advance to explain the natural properties of the goods to the customs, so as to avoid being misjudged as artificial synthetic sand or mineral products containing dangerous components. In addition, pay attention to the integrity of the seal of the bulk carrier. If the seal is damaged, it is necessary to issue a certificate to the shipping company immediately to avoid being identified as having problems with cargo right. **status:** suggested **Author:** Evelyn Li **Date:** 2026-09-27 ### Answer 7 The supply chain planning of imported river sand needs to balance cost and supply stability. If the enterprise has long-term demand for river sand import, it can adopt the mode of "centralized procurement + batch declaration", sign an annual framework agreement with the supplier to lock the procurement price, and use the temporary storage function of the bonded port area to store river sand in the bonded port area temporarily, and declare for import in batches according to the demand of domestic infrastructure projects, which greatly reduces the cost of capital occupation. In addition, you can optimize the transportation route, choose bulk carriers that sail directly to Shanghai Yangshan Port to avoid cargo loss and time delay caused by transshipment, and sign a long-term service agreement with the agency company to enjoy more favorable customs declaration rates and logistics discounts, further reducing the overall supply chain cost. **status:** suggested **Author:** Jason Wu **Date:** 2026-09-27 ## Related Categories - [Import Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-import-agency/) - [Export Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-export-agency/) - [Export Tax Rebate Q&A](https://www.sh-zhongshen.com/en/qa/cat-export-tax-rebate/) - [Freight Forwarding Q&A](https://www.sh-zhongshen.com/en/qa/cat-freight-forwarding/) - [Forex Settlement Q&A](https://www.sh-zhongshen.com/en/qa/cat-forex-settlement/) - [Entrepôt Trade Q&A](https://www.sh-zhongshen.com/en/qa/cat-entrepot-trade/) - [General Trade Q&A](https://www.sh-zhongshen.com/en/qa/cat-general-trade/) ## Related Resources - [Trade Services](https://www.sh-zhongshen.com/en/services/) - [Trade Cases](https://www.sh-zhongshen.com/en/cases/) - [Trade Wiki](https://www.sh-zhongshen.com/en/wiki/) - [Trade Class](https://www.sh-zhongshen.com/en/guide/) - [Global Trade Services](https://www.sh-zhongshen.com/en/country/) ## Structured Data ```json [ { "@context": "https://schema.org", "@type": "QAPage", "inLanguage":"en", "isPartOf": { "@id":"https://www.sh-zhongshen.com/en/#website" }, "publisher":{ "@id":"https://www.sh-zhongshen.com/en/#organization" }, "mainEntity": { "@type": "Question", "name": "Can We Entrust a Foreign Trade Agency to Handle Customs Declaration for 5000 Tons of Natural River Sand Imported from Southeast Asia?", "text": "I am the procurement director of a building material trading company in Shanghai.
