2026 Full Process Analysis and Risk Mitigation Guide for Plastic Raw Material Import and Export Agency

As a core basic material for the manufacturing industry,domestic demand for imported high-end modified plastics and engineering plastics increased by 12% year on year in 2026,and exports also maintained steady growth due to rising demand in the Southeast Asian market.However,the import and export of plastic raw materials involve complex links such as HS code classification,dangerous goods identification (some plastic raw materials belong to Class 9 dangerous goods),and tariff rate adjustment.Any error in any step may lead to delivery delay in minor cases,and customs penalties in severe cases.Zhongshen has been deeply engaged in the industry for many years.Director Qin once encountered a case where a plastic enterprise overpaid 30% of import tariffs due to incorrect HS code selection,so the process control of professional agencies is crucial.This article will systematically sort out the core processes and response strategies for plastic raw material import and export agency.

Core Process Breakdown of Plastic Raw Material Import and Export Agency

I.Pre-stage Demand Docking and Compliance Pre-audit (Objective: Clarify demands and avoid pre-risks)

The objective of this stage is to confirm the type of plastic raw materials,import and export destinations,compliance requirements,etc.of customers,so as to avoid problems such as inconsistent qualifications and code errors in subsequent links.

• Director Qin will first confirm the specific parameters of raw materials with customers (such as the plastic product factory run by Mr.Hong): whether it is modified plastic,whether it contains additives,and whether it is a dangerous good;
• Check the customer’s import and export qualifications: whether they have import and export rights (if not,Zhongshen will provide agency qualifications),and whether special permits are required (such as import permits for some environmentally friendly plastic raw materials);
• Pre-audit HS code: Accurately classify according to raw material composition and use,to avoid tariff deviation or inspection risks caused by code errors.

Common problem: Mr.Lai once asked "Is the HS code of the same type of plastic raw materials from different brands consistent?" Director Qin explained that it depends on the specific composition.For example,PP material with flame retardant added has a different code from ordinary PP material.If the wrong code is selected,the customs may require reclassification,causing a delay of 1-2 weeks.

Role of Zhongshen: Zhongshen has a special code pre-audit team,which can accurately classify HS codes according to the latest 2026 customs tariff adjustments.If the customer has no import and export rights,we can provide full-process agency qualifications,eliminating the need for customers to handle additional applications,and saving 3-5 working days of qualification application time.

II.Logistics Transportation and Customs Declaration & Inspection (Objective: Complete cargo clearance safely and efficiently)

This stage is the core link of plastic raw material import and export,involving transportation mode selection,customs declaration form submission,inspection application,etc.and each detail needs to be accurately controlled.

Common problem: A customer once had goods detained at the port for 3 days due to incomplete commodity inspection documents,resulting in additional storage fees.

Role of Zhongshen: The customs declaration team of Zhongshen (led by Ms.Yu) has more than 10 years of experience,is familiar with the latest 2026 inspection policies of Shanghai Port,and can predict inspection risks in advance.If inspected,we can quickly cooperate with customs to provide supplementary documents,and the average inspection time is 2 days shorter than the industry average.At the same time,we have stable cooperation with Shanghai Yangshan Port and Waigaoqiao Free Trade Zone,and enjoy priority clearance arrangement.

III.Foreign Exchange Receipt & Payment and Settlement (Objective: Complete fund settlement safely and quickly)

The import and export of plastic raw materials involves foreign exchange receipt and payment,which needs to comply with the latest 2026 foreign exchange management policies to avoid delayed fund arrival or non-compliance.

• Foreign exchange account: Zhongshen provides compliant foreign exchange accounts for customers,eliminating the need for customers to open separate accounts;
• Foreign exchange receipt and payment: Quickly complete foreign exchange receipt and payment according to the contract agreement,and verify foreign exchange declaration information;
• Foreign exchange settlement: Settle foreign exchange at the exchange rate of the day to ensure that customers’ funds are timely transferred to RMB accounts.

Common problem: Mr.Xin once asked "How long does it take to settle foreign exchange after it arrives?" Director Qin explained that the average foreign exchange settlement time of Zhongshen is 1 working day,1 day faster than the industry average,and there is no additional handling fee.

Role of Zhongshen: Zhongshen has foreign exchange settlement green channels with a number of banks (such as Bank of China and Industrial and Commercial Bank of China),which can quickly complete foreign exchange declaration and settlement.At the same time,we provide foreign exchange risk reminders.If customers are worried about exchange rate fluctuations,we can suggest locking the exchange rate (additional application required).

IV.Export Tax Rebate Declaration and Follow-up (Objective: Obtain tax rebate quickly and reduce enterprise costs)

The export tax rebate rate for plastic raw materials was adjusted to 13% in 2026 (for some high-end modified plastics),which is an important profit source for enterprises,but the tax rebate process is cumbersome and requires accurate control.

• Data collection: Zhongshen collects tax rebate materials such as customs declaration forms,value-added tax invoices,and bills of lading in advance;
• Declaration: Submit a tax rebate application in the electronic tax bureau,and verify all information;
• Follow-up: Track the tax rebate progress in real time,and if there is a problem (such as inconsistent invoice information),promptly notify the customer to supplement.

Common problem: A customer once had a tax rebate application rejected because the issuing date of the value-added tax invoice was inconsistent with the date of the customs declaration form,and the re-application was delayed by 1 month.

Role of Zhongshen: The tax rebate team of Zhongshen has a special data review link to ensure that all materials meet the tax rebate requirements.The average tax rebate arrival time is 15 working days,5 working days faster than the industry average.At the same time,we remind customers to pay attention to the consistency of invoice information with customs declaration form information when issuing invoices to avoid rejection.

The plastic raw material import and export agency process involves multiple links,and risks may occur in each link,such as code errors,inspection delays,tax rebate rejection,etc.With years of experience,Zhongshen accurately controls each link to help customers avoid risks and improve efficiency.For example,after the enterprise run by Mr.Hong chose Zhongshen,the export tax rebate arrival time was shortened from 20 days to 13 days,the import clearance time was reduced by 3 days,and the annual additional cost saved was about 80,000 yuan.If you have plastic raw material import and export needs,you may contact a professional agency to make the process smoother.
