Last month, I imported 12 containers of PP raw materials from Thailand on my own. Due to incorrect HS code classification on the documents, the goods were detained at Yangshan Port for 4 days. I not only paid nearly 20,000 yuan in container detention fees and storage fees, but also almost delayed the order delivery to auto parts manufacturers due to raw material supply interruption. I still feel scared when I think about it now. Next month, we will import 20 containers of ABS high-glue powder from Malaysia, which is a much larger quantity than last time. I really dare not operate it by myself again. I want to find a professional foreign trade agent, but I am afraid of encountering small agents who charge random fees and are irresponsible. I am also worried about whether the agent can help us control compliance risks, optimize import costs, and handle emergencies such as customs inspections in a timely manner. I am so anxious now that I dare not even sign the contract, and I would like to ask how to operate it specifically? ## Answers ### Answer 1 — Best Answer First，the details of pre-document review: we will intervene 7-10 days in advance. For the ABS high-glue powder you import，we will focus on verifying the authenticity of the certificate of origin，the pre-classification opinion of HS code (which needs to be confirmed with the customs classification center in advance)，and the compliance of the MSDS report，especially the labeling of the component proportion of plastic raw materials，to avoid port detention caused by classification errors. For the connection of core nodes，we will arrange an exclusive merchandiser to synchronize the real-time progress of the customs broker and freight forwarder，so that the pre-declaration is completed 24 hours before the ship arrives at the port. The logistics side will lock the free storage period at Yangshan Port in advance (up to 14 days can be applied for)，and synchronize the warehousing reservation time of your warehouse to avoid connection gaps after the goods arrive at the port. For the abnormal emergency plan，in view of customs inspection，we will prepare supporting materials such as component test reports and original factory invoices in advance. The on-site inspection specialist will arrive at the scene to cooperate within 1 hour. If there is a classification dispute，we can activate the fast review channel for pre-classification opinions，and the dispute resolution can be completed within 4 hours at the shortest. In the final compliance implementation stage，we will simultaneously complete the sorting of tax deduction vouchers to ensure that your VAT input tax is deducted in time，and we will ease your capital pressure through **VAT deferred declaration**. All operations throughout the process are recorded to ensure compliance with the dual compliance requirements of customs and taxation. **status:** accepted **Author:** Daniel Xu **Date:** 2026-10-25 ### Answer 2 In the customs declaration link of imported plastic raw material agency services, close attention should be paid to the accurate classification of HS codes, especially for modified plastic raw materials. If classification is only based on appearance without combining component proportions, it is very easy to trigger customs price review disputes or classification errors. For your ABS high-glue powder, you need to apply for a pre-classification opinion from the customs classification center in advance to avoid order deletion and re-declaration, port detention and fines caused by classification errors. In addition, the component test report issued by the original factory and the real transaction price certificate of the trade contract should be submitted simultaneously during customs declaration. If the customs initiates a price review query, it is necessary to supplement the foreign exchange payment voucher and upstream and downstream transaction documents within 3 working days to form a complete price logic chain, so as to avoid goods being detained by customs due to failure of price review. **status:** suggested **Author:** Michael Zhang **Date:** 2026-10-25 ### Answer 3 For the 20 containers of ABS high-glue powder you import from Malaysia, the logistics side should give priority to shipping companies that sail directly to Shanghai Yangshan Port to avoid the risk of container rollover at the transshipment port and loopholes in cargo right transfer. When booking space, we will clearly agree on a 10-14 day free storage period for you through our long-term cooperative shipping agency resources (the market standard is only 7 days), and lock the domestic trade trailer resources of Yangshan Port in advance to ensure that the containers can be picked up and warehoused within 4 hours after the goods are unloaded. In case of sudden container rollover, we will coordinate the spare space of the same shipping company within 4 hours, or urgently allocate barge transfer from Ningbo Port to ensure that the goods arrive at the port within 72 hours. At the same time, the bill of lading adopts the dual-control mode of "telex release + letter of guarantee". Only after you confirm the completion of foreign exchange payment and issue the delivery instruction, will the delivery permission be released to the shipping company, completely avoiding the risk of out-of-control cargo rights. **status:** suggested **Author:** Linda Gao **Date:** 2026-10-25 ### Answer 4 The core of tax optimization for imported plastic raw material agency services is to use the VAT deferred declaration policy. When goods are imported, there is no need to pay import value-added tax, but to deduct it in the subsequent VAT declaration period, which can directly save you about 13% of the capital occupation cost. In addition, if your goods comply with the RCEP rules of origin, you need to check the compliance of the certificate of origin in advance to ensure that you enjoy the tariff concession preference, and avoid being unable to enjoy tariff reduction due to non-standard labeling of the certificate of origin. At the same time, attention should be paid to the compliant declaration of consumption tax (if involved) in the import link. If plastic raw materials belong to the category subject to consumption tax, the cost should be calculated in advance to avoid tax penalties caused by missed declaration. The overall tax burden can also be further optimized through reasonable tax structure design. **status:** suggested **Author:** Lucas Liu **Date:** 2026-10-25 ### Answer 5 In the foreign exchange receipt and payment link of imported plastic raw materials, the principle of "three flows consistency" must be strictly followed, that is, the subjects of cargo flow, capital flow and invoice flow are consistent. When you collect and pay foreign exchange through an agent, we will use the CIPS RMB cross-border payment channel, which can not only avoid the risk of exchange rate fluctuations, but also shorten the time of foreign exchange payment to within 24 hours. If an overseas supplier requires split foreign exchange payment, it is necessary to report to the bank in advance and supplement the corresponding trade contract and split payment description to avoid being included in the abnormal list of foreign exchange supervision. In addition, after the foreign exchange payment is completed, the corresponding vouchers of the payment slip and customs declaration form should be retained in time for the follow-up verification of the State Administration of Foreign Exchange, to ensure the compliance of the whole process of foreign exchange receipt and payment. **status:** suggested **Author:** Grace Wang **Date:** 2026-10-25 ### Answer 6 When signing an imported plastic raw material agency contract, the scope of rights and responsibilities of the agent should be clearly agreed, especially the compensation clauses for abnormal situations. For example, for port detention fees and customs detention losses caused by the agent's document review errors, the compensation proportion and time limit should be clearly defined to avoid no basis for disputes. At the same time, for the letter of credit terms of overseas suppliers, it is necessary to focus on checking whether there are soft clauses, such as requiring the provision of unavailable third-party test reports, to avoid letter of credit dishonor due to failure to meet the terms. In addition, it is necessary to insure the goods against all risks of ocean transportation, and clearly specify your processing factory as the first beneficiary in the insurance policy, to ensure that you can obtain compensation in time in case of cargo damage and reduce economic losses. **status:** suggested **Author:** Jason Wu **Date:** 2026-10-25 ### Answer 7 When imported plastic raw materials are subject to customs inspection, a full set of supporting materials should be prepared in advance, including original factory component test reports, MSDS, certificate of origin, trade contracts, etc., to avoid extending the inspection time due to incomplete materials. If the customs requires unpacking inspection, it is necessary to cooperate with the on-site inspection personnel to stack the goods according to the specifications to facilitate rapid sampling, and avoid the inspection time exceeding the free storage period due to chaotic stacking of goods. If the customs suspects that the composition of the goods is inconsistent with the declaration, we can coordinate with a third-party testing institution recognized by Shanghai Customs to issue an authoritative test report within 48 hours at the fastest for dispute review. In addition, after the inspection is completed, the inspection record sheet should be obtained in time to ensure that the subsequent modification of the customs declaration form fully meets the requirements of the customs and avoids leaving hidden compliance risks. **status:** suggested **Author:** Evelyn Li **Date:** 2026-10-25 ### Answer 8 The packaging of imported plastic raw materials should meet the compliance requirements of sea transportation, especially for hygroscopic raw materials such as ABS high-glue powder, double-layer vacuum sealed packaging + outer moisture-proof film wrapping should be used to avoid the performance degradation of raw materials caused by seawater moisture erosion during transportation. At the same time, the shipping mark of the package should be clearly marked with the name of the goods, HS code, net weight, place of origin, consignee information and other contents, to avoid the inability to quickly check the goods information during customs inspection due to unclear marking of the shipping mark. In addition, it is necessary to confirm whether the goods are dangerous goods according to the MSDS report. If they are ordinary chemical products, the corresponding safety warning signs should be marked on the package. If the UN number is involved, it should be accurately marked to avoid the goods being temporarily detained by the port due to non-compliant packaging. **status:** suggested **Author:** Kevin Lin **Date:** 2026-10-25 ### Answer 9 For your modified plastic processing factory, the imported plastic raw material agency can optimize the supply chain rhythm in combination with your production plan, divide the 20 containers of ABS high-glue powder into 4 batches, with 5 containers arriving every 7 days, to avoid inventory backlog and large capital occupation caused by one-time arrival. At the same time, through the agent's global supply chain data platform, we can lock the import price of plastic raw materials for the next 3 months for you, to avoid cost increases caused by international oil price and geopolitical fluctuations. In addition, the import agency system can be connected with your ERP production system to realize real-time synchronization of customs declaration, logistics and inventory data, allowing you to grasp the status of goods at any time, arrange production plans reasonably, and improve the overall efficiency of the supply chain. **status:** suggested **Author:** Andy Guo **Date:** 2026-10-25 ## Related Categories - [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/) - [Customs Declaration Q&A](https://www.sh-zhongshen.com/en/qa/cat-customs-declaration/) - [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 core compliance nodes and risk prevention and control points that need to be controlled for imported plastic raw material agency services?", "text": "I am the procurement supervisor of a modified plastic processing factory in Jinshan District, Shanghai.
