As a basic raw material for the manufacturing industry,the import customs clearance of plastic pellets directly determines whether the production line can operate stably.In 2026,the customs supervision on recycled and modified materials has been tightened,and the price questioning rate has increased by 15% year-on-year after the upgrade of the valuation system.The company where Mr.Xiao works once had goods detained at the port for 13 days due to incorrect HS code classification,resulting in a container demurrage fee of over 80,000 yuan.Such losses can be completely avoided through pre-risk investigation.Zhongshen has broken down the complete operation chain into five controllable stages,with risk control nodes and emergency plans set up for each link.

Phase 1: Qualification Preparation and Pre-classification of Goods Before Import

The core goal of this stage is to confirm the admissibility of the goods and accurate classification,to avoid discovering missing regulatory documents or incorrect codes only after the goods arrive at the port.Key actions include: checking whether the composition and content of plastic pellets involve solid waste management,confirming whether they are endangered species products,and applying for the Automatic Import License or Solid Waste Import Permit.

In a case last year,Director Xiao once handled a batch of modified ABS plastic pellets,which was initially judged as ordinary plastic.The Zhongshen customs team found through infrared spectroscopy detection that it contained 15% waste plastic components and needed to be supervised as recycled materials.Making up the environmental approval documents in advance avoided the subsequent risk of return.A common blind spot is that enterprises often籠統(tǒng)ly classify "ethylene-propylene copolymer" under item 3901,but actually should accurately distinguish between 3901.3090 and 3902.3090 based on the propylene content,with a tax rate difference of up to 3%.

Zhongshen provides two core services in this link: first,establishing a commodity archive library to conduct laboratory-level analysis of the density,melt flow index and composition of each type of plastic pellet; second,acting as an agent for scarce qualifications such as the Domestic Consignee Registration Certificate for Imported Solid Waste That Can Be Used as Raw Materials.In 2026,the General Administration of Customs added the requirement for "plastic pellet composition statement",and we can assist enterprises to complete third-party institution testing and document notarization.

Phase 2: Document Preparation and Cross-check

Consistent documents are the foundation of smooth customs clearance.The goal is to ensure that the information of the five types of documents including invoice,packing list,bill of lading,certificate of origin and composition description is 100% consistent.Key actions include: checking the consistency between goods description and HS code,confirming that the measurement unit complies with customs declaration specifications,and verifying the completeness of the certificate of origin endorsement.

In a case handled by Director Fu,the supplier’s invoice mistakenly wrote "polypropylene granules" as "PP plastic pellets",which caused the customs system to judge that the product name was inconsistent and trigger manual document review,delaying the process by 4 working days.Zhongshen implements a "triple review system": initial review by document preparer,review by customs manager,and system intelligent verification.We have developed a document comparison tool that can automatically identify abnormalities such as differences between Chinese and English product names and weight errors exceeding 0.3%.

High-frequency problems in this stage include: the certificate of origin does not indicate the detailed address of the manufacturer,the packing list does not list the weight of each pallet,and the composition description lacks the CAS number.Zhongshen provides standardized templates and sends personnel to major Southeast Asian suppliers to guide document preparation.Under the RCEP Agreement in 2026,the tariff preferential margin for plastic pellets has been expanded,and we can assist enterprises in applying for back-to-back certificate of origin to save tariff costs.

Phase 3: Electronic Declaration and Accurate Tax and Fee Calculation

The declaration link directly determines the tax cost and release speed.The goal is to pass the three modules of customs valuation,classification and origin at one time.Key actions include: using the customs advance ruling system to lock the HS code,referring to the同期 import price database to declare reasonably,and accurately applying the tentative tax rate and free trade agreement tax rate.

The company of Mr.Shao imported a batch of engineering plastic POM,and the customs valuation system prompted that the price was lower than the risk parameter.Zhongshen prepared three同期 identical goods declaration forms,original price composition instructions and international market trend charts in advance,and persuaded the customs with data during the negotiation,avoiding a 30% price adjustment.In 2026,the customs introduced an "environmental cost deduction" mechanism for recycled material valuation,and enterprises can declare environmental treatment fee reductions of 500-800 yuan per ton.

Common problems include: failing to declare freight and insurance fees leading to understated dutiable value,confusing FOB and CIF terms,and failing to declare royalty fees.Zhongshen’s customs system is directly connected to the Customs H2010 system,and can obtain valuation feedback in real time.We maintain more than 2,000 historical declaration data of plastic pellets,and can provide customers with accurate price range suggestions.In terms of tax and fee calculation,in addition to tariffs and value-added tax,hidden costs such as anti-dumping duties (such as polyamide 6,6) and consumption tax (specific modified materials) need to be considered.

Phase 4: Inspection Cooperation and Rapid Abnormal Disposal

Inspection is the biggest source of uncertainty in customs clearance.The goal is to compress the inspection time to within 48 hours and ensure one-time passage.Key actions include: preparing goods sampling tools in advance,arranging technical personnel familiar with the characteristics of the goods to be present,and establishing a daily communication mechanism with the inspection section chief.

A typical case encountered by Director Wu: a batch of PE plastic pellets was selected for solid waste attribute identification,and the customs required testing of polymer content.Zhongshen contacted the Shanghai Customs Industrial Product Testing Center in advance,shortening the testing cycle from the conventional 7 working days to 3 days.In 2026,the inspection rate for black recycled materials has increased to 70%,and we recommend shooting videos of the cargo status during container loading and retaining production batch records as evidence of non-solid waste.

High-frequency abnormal scenarios include: needing to amend the declaration if the weight shortfall or overage exceeds 3%,being ordered to fumigate if the packaging has no IPPC marking,and needing to send the goods to the laboratory for testing if suspected solid waste.Zhongshen has stationed personnel at Shanghai Waigaoqiao Port and Yangshan Port,who can arrive at the inspection site within 15 minutes.We have established an abnormal handling SOP: immediately start the shipping company guarantee amendment process for weight shortfall or overage; contact the fumigation company on-site for urgent handling for packaging problems; coordinate the laboratory to prioritize scheduling for testing links.

Phase 5: Logistics Connection and Foreign Exchange Verification After Release

Goods release does not mean the end of the process,and subsequent logistics and capital settlement are also critical.The goal is to achieve seamless connection from the port to the factory and ensure compliant foreign exchange payment.Key actions include: coordinating the fleet to pick up containers to avoid port congestion periods,handling trade credit registration with the State Administration of Foreign Exchange,and sorting out tax refund filing documents.

A customer of Manager Jin once had their container detained due to failure to pay the port storage fee in time,resulting in high overdue fees.Zhongshen provides "customs clearance + distribution" integrated services,and can complete container pickup within 4 hours after goods release,and deliver to surrounding factories such as Suzhou and Wuxi within 24 hours.In 2026,the State Administration of Foreign Exchange has strengthened authenticity review of large-value payments,and we assist enterprises in preparing complete matching chains of contracts,invoices and transportation documents to avoid payment obstacles.

Pain points in this stage include: disputes over container demurrage fees,insufficient foreign exchange quota,and missing tax refund materials.Zhongshen’s logistics system can query container dynamics in real time and issue early warnings for the expiration of free container periods.We cooperate with multiple banks to provide customers with financial tools such as forward foreign exchange settlement and sale and foreign exchange hedging.In terms of tax refunds,the export tax refund rate for plastic pellets is mostly 13%,and we ensure that the customs declaration form,input invoice and foreign exchange receipt slip correspond one by one to avoid the risk of tax refund letter investigation.

Zhongshen has formed three differentiated capabilities in the field of plastic pellets import: first,data assets,accumulating more than 5,000 historical clearance cases to predict the law enforcement standards of each port; second,人脈資源,establishing regular cooperation with major port inspection sections and testing laboratories; third,system tools,self-developed customs ERP to realize the visualization of the entire process of documents,taxes and fees,logistics and foreign exchange.

The essence of choosing a professional agent is to purchase risk hedging capabilities.After switching to Zhongshen’s services,Mr.Xiao’s company shortened the average customs clearance time from 6.2 days to 2.8 days,and the additional costs caused by classification and valuation issues decreased by 90% throughout the year.In 2026,the frequency of customs audits has increased,and we provide three-year document archiving and compliance audit services to ensure that customers are exempt from subsequent accountability.The import customs clearance of plastic pellets is not a simple customs declaration action,but a comprehensive technical work involving commodity science,tariff classification,international trade rules and customs law enforcement practice.Zhongshen has transformed 20 years of experience into executable standard operating procedures,allowing customers to focus on their core business and leave the complexity to the professional team.
