My goods have been in transit by sea for 12 days and will arrive at Yangshan Port in one week. This is my first time importing 20 containers of cultural paper from Vietnam, and I have no idea about the procedures of import customs clearance. I heard from peers before that some people had their goods detained at the port for a week due to document errors and omissions. They not only paid liquidated damages to downstream customers, but also paid nearly CNY 20,000 in port storage fees and container detention fees, which makes me shudder just thinking about it. I have contacted three customs brokers, and the process details they mentioned vary greatly. I don't know how to cooperate with them either, and I am very anxious now. I just want to ask how imported paper customs brokerage actually works? Are there any specific operation details that can avoid port detention and cargo seizure? And what materials do I need to prepare in advance to avoid mistakes? ## Answers ### Answer 1 — Best Answer First，the details of pre-document review: you need to submit the full set of documents to the broker 3-5 days in advance，including **certificate of origin，phytosanitary certificate，packing list，commercial invoice，bill of lading**. The broker will focus on checking whether the paper raw material source indicated on the phytosanitary certificate complies with China's environmental protection standards，and whether the cargo weight and quantity on the packing list are completely consistent with those on the bill of lading，to avoid triggering customs document review warnings due to document discrepancies. In terms of core node connection: one day before the goods arrive at the port，the broker will complete the pre-entry of import declaration，and simultaneously coordinate with the port to arrange document exchange. After the customs declaration form is released，the broker will immediately coordinate inspection (if required)，and communicate with on-site customs officers in advance about the attributes of the goods to ensure inspection efficiency. After release，the broker will arrange trucks to pick up the containers immediately to connect with domestic distribution. Exception response plans need to be formulated in advance: in case of customs valuation query，the broker will immediately provide supporting materials such as purchase contracts and payment receipts. If sampling inspection is required for environmental protection testing，the broker will simultaneously apply for port storage fee reduction procedures. If documents are temporarily missing，the broker will assist in applying for customs guarantee release to avoid cargo detention at the port. Final compliance implementation: after customs clearance is completed，the broker will sort out and deliver the full set of compliance documents (including customs payment receipt and release notice)，to ensure the compliance of the whole process of subsequent tax deduction and inventory registration，and assist in completing the compliance filing of foreign exchange receipt and payment. **status:** accepted **Author:** Victor Sun **Date:** 2026-10-04 ### Answer 2 When clearing imported paper products, it is necessary to focus on the logical closed loop of the customs valuation link: the customs will take the transaction price of identical or similar goods as the benchmark. If the declared price is significantly lower than the average market price, it will trigger a valuation query. At this time, you need to provide real transaction vouchers between the buyer and the seller, including email communication records, historical transaction data, raw material cost calculation forms, etc., to avoid order deletion and re-declaration due to inability to provide evidence, which will extend the customs clearance cycle. At the same time, it is necessary to ensure that the commodity code on the customs declaration form is accurate. The corresponding code tax rates for different types of paper (such as cultural paper and packaging paper) vary greatly. If the code is misreported, it will not only lead to errors in tax calculation, but also may trigger customs inspection. **status:** suggested **Author:** Daniel Xu **Date:** 2026-10-04 ### Answer 3 The logistics route for imported paper products should be optimized in combination with the cargo volume and port congestion: for bulk goods of more than 20 containers, direct shipping routes to Yangshan Port are preferred to avoid cargo ownership risks and time delays caused by transshipment. In case of port congestion, you need to communicate with the broker 72 hours in advance about the port change plan, or apply for an extension of the free storage period. At the same time, you need to pay attention to the starting time of container detention fees. Generally, the free container period for shipping companies is 7-10 days. If the goods cannot be cleared in time after arriving at the port, you need to apply to the shipping company for an extension of the free container period in advance to avoid high container detention fees. In addition, the bill of lading endorsement must be consistent with the qualification of the consignee. If it is a straight bill of lading, you need to confirm the customs clearance qualification of the consignee in advance to avoid document exchange failure. **status:** suggested **Author:** Eric Zhou **Date:** 2026-10-04 ### Answer 4 Imported paper products can optimize cash flow through the VAT deferment strategy: eligible import enterprises can apply for VAT deferment during customs clearance, without paying import value-added tax at the customs clearance link, but deduct it in the subsequent VAT declaration period. This measure can reduce the capital occupation cost by about 13%. It should be noted that two conditions must be met to apply for VAT deferment: first, the enterprise is a general taxpayer, and second, the goods directly enter the domestic sales link rather than bonded warehousing. At the same time, it is necessary to ensure that the information on the customs payment receipt is consistent with the VAT declaration form, to avoid failure to deduct due to inconsistent information. In addition, if the goods are imported from countries that have signed free trade agreements with China, you can apply for tariff reduction and exemption with a valid certificate of origin to further reduce import costs. **status:** suggested **Author:** Linda Gao **Date:** 2026-10-04 ### Answer 5 The receipt and payment of foreign exchange for imported paper products must strictly comply with the compliance requirements of cross-border payment: if RMB settlement is adopted, payment can be completed through the CIPS system to ensure the traceability of transaction tracks. If foreign currency settlement is adopted, you need to submit import declaration forms, contracts, invoices and other materials to the bank before foreign exchange payment to complete the payment filing. You should avoid receiving and paying foreign exchange through personal accounts, which will trigger a compliance warning from the State Administration of Foreign Exchange and lead to account freezing. At the same time, you need to ensure that the amount of foreign exchange received and paid is consistent with the total value of the goods on the customs declaration form. If there are additional expenses such as commission and freight, they need to be declared separately on the customs declaration form to avoid settlement failure due to amount inconsistency. **status:** suggested **Author:** Michael Zhang **Date:** 2026-10-04 ### Answer 6 The purchase contract for imported paper products must clarify the cargo ownership transfer and force majeure clauses: the cargo ownership transfer node should be agreed as "after the goods are loaded on board", to avoid disputes caused by unclear ownership of cargo during transportation. The force majeure clause must explicitly include port congestion, customs inspection delay and other situations. If the delivery of goods is delayed due to the above reasons, part or all of the liability for breach of contract can be exempted. At the same time, intellectual property clauses must be agreed to ensure that the printed patterns, trademarks, etc. on the imported paper do not infringe the intellectual property rights of domestic third parties, so as to avoid the goods being detained and inspected by the customs. In addition, you can require the supplier to provide a performance bond. If the supplier cannot deliver the goods on time or the quality of the goods does not meet the requirements, you can claim compensation through the bond. **status:** suggested **Author:** Evelyn Li **Date:** 2026-10-04 ### Answer 7 For on-site inspection of imported paper products, it is necessary to focus on cooperating with the sampling inspection of the customs: the customs will select some samples for environmental protection testing according to the type, origin and other factors of the goods, including formaldehyde content, heavy metal content, etc. At this time, you need to prepare the MSDS report of the goods, raw material testing report and other materials in advance to assist the customs in completing the testing. In case of seal authenticity identification, you need to provide the seal certificate issued by the shipping company to avoid the goods being detained and inspected due to abnormal seals. In addition, during unpacking inspection, you need to ensure that the goods are stacked neatly to facilitate on-site inspection by the customs, and avoid extended inspection time and port storage fees caused by messy goods. **status:** suggested **Author:** Cindy Chen **Date:** 2026-10-04 ### Answer 8 The supply chain planning for imported paper products should be optimized in combination with inventory and customs clearance time limit: for paper with seasonal demand (such as Spring Festival couplet paper), import should be arranged 2-3 months in advance, and sufficient time for customs clearance and transportation should be reserved to avoid stock shortage caused by delayed arrival of goods. At the same time, the CIF trade term can be adopted to transfer the responsibility of logistics and customs clearance to the supplier, but it must be clarified in the contract that the supplier needs to entrust a qualified customs broker to avoid customs clearance delay caused by insufficient broker qualification. In addition, an inventory linkage mechanism can be established to adjust the import volume according to the domestic inventory level, avoid inventory overstock or shortage, and optimize the efficiency of capital occupation. **status:** suggested **Author:** Kevin Lin **Date:** 2026-10-04 ## 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": "What are the complete operation procedures and core control nodes of customs brokerage for imported paper products?", "text": "I am a small and medium-sized trader engaged in office stationery wholesale in Shanghai.
