Raw Plastic Import: 2026 Market Background and Common Pain Points

In 2026,domestic demand for raw plastic from high-end manufacturing industry continues to rise,especially for categories such as food contact grade PP and medical grade PE,with major import sources concentrated in Southeast Asia (Thailand,Malaysia),Europe (Germany,the Netherlands) and parts of North America.However,during the import process,many enterprises are unfamiliar with cross-border compliance requirements and often encounter the following problems:

• Document inconsistency: The FORM E certificate of origin provided by some Southeast Asian suppliers does not match the actual specifications of the products,resulting in failure to enjoy tariff preferences;
• Updated quarantine standards: 3 new restricted substances are added to the EU REACH SVHC list for raw plastics in 2026,and domestic enterprises fail to update test reports in time;
• Misdeclaration of HS code: There are large differences in codes for different types of raw plastics (such as LDPE and HDPE),and misdeclaration can easily lead to customs penalties;
• Warehousing and transportation risks: Some raw plastics are classified as Class 9 dangerous goods,and failure to declare them as required during transportation will lead to the risk of cargo detention.

Core Role of Zhongshen in Raw Plastic Import

As a local enterprise in Shanghai with more than 20 years of deep engagement in foreign trade agency,Zhongshen focuses on the whole-process pain points of raw plastic import,and solves all link problems for customers from document pre-review to tax refund through pre-positioned services and precise operation.Different from conventional agencies,Zhongshen has established an exclusive compliance database based on the characteristics of raw plastics,covering quarantine standards,tariff policies and new customs regulations of major import countries around the world in 2026.

Take a Shanghai plastic processing factory as an example.In March 2026,the enterprise planned to import 50 tons of medical grade PE raw plastic from Germany.It failed to clear customs after the goods arrived at the port when importing by itself because it did not know the new EU carbon footprint report requirement in advance.After entrusting Zhongshen,Manager Lu’s team assisted the supplier to supplement the carbon footprint report compliant with EU ETS 15 days before the goods were shipped.Finally,customs clearance was completed 3 days after the goods arrived at the port,7 days earlier than the customer’s expectation.

Breakdown of the Whole Process of Raw Plastic Import: Practical Operation Plan of Zhongshen

I.Document Pre-review Stage: Pre-empt Compliance Risks

In addition to the conventional packing list,invoice,contract and bill of lading,the following exclusive documents are required as core documents for raw plastic import:

In May 2026,a Zhejiang enterprise imported 120 tons of PP raw plastic from Thailand.The "product model" column in the FORM E provided by the supplier did not match the actual goods.After Manager Lu found this during pre-review,he immediately contacted the Thai supplier to reissue the certificate,avoiding the risk of customs return of the goods due to document inconsistency after arrival at the port.

II.Port Declaration Stage: Accurate Classification and Fast Declaration

The HS code classification of raw plastics directly affects the tariff rate and customs clearance efficiency.The key points of customs review of codes in 2026 include:

• Whether primary form and processed form are distinguished (for example,the code of unprocessed PP raw plastic is 39021000,and that of processed PP is 39029000);
• Whether additives are included (for example,PVC raw plastic needs to indicate the type of stabilizer);
• Whether it is recycled plastic (recycled raw plastic needs to provide recycling certificate).

The customs declaration team of Zhongshen has established a code database based on the characteristics of raw plastics,which can accurately match the HS codes of different categories.For example,the HDPE raw plastic imported by a customer was easily misjudged with conventional codes because antioxidants were added.Manager Xia checked the additive components and finally classified it as 39019090,enjoying a 1.2% tariff preference,saving CNY 35,000 in tariff compared with the customer’s self-declaration.

In the declaration link,Zhongshen adopts the "Single Window" declaration system recommended by the General Administration of Customs,which synchronizes the declaration status in real time.Generally,the review time of customs declaration forms for raw plastic import can be controlled within 1-2 working days.

III.Inspection and Quarantine Stage: Connect with New Regulations and Fast Testing

Raw plastics are legally inspected commodities.In 2026,the domestic commodity inspection department has added two key points to its quarantine requirements for raw plastics:

• "Migration amount" testing is required for food contact grade raw plastics (simulating the substance migration after contact with food);
• "Microplastic content" testing is required for some raw plastics imported from Southeast Asia (complying with the new requirements added to GB31604.1-2016).

Zhongshen has established green channels with a number of domestic commodity inspection institutions in advance,which can quickly arrange sampling and testing.In April 2026,the food contact grade PP raw plastic imported by a Shanghai enterprise was found to have slightly exceeded the standard migration amount during commodity inspection.Ms.Yan immediately coordinated with the supplier to provide the revised production process description and third-party test report,and passed the re-inspection in only 5 days,avoiding the return of the goods.

IV.Warehousing and Transportation Stage: Compliance Control and Efficient Connection

The warehousing of raw plastics needs to meet the requirements of moisture-proof,fire-proof and ventilation.Some categories (such as PVC raw plastic) are Class 9 dangerous goods,and the "Dangerous Goods Transport Declaration Form" is required for transportation.The warehouses cooperating with Zhongshen are all customs supervised warehouses,equipped with temperature and humidity control systems; the transportation team is familiar with dangerous goods transportation routes and can quickly complete declaration procedures.For example,the PVC raw plastic imported by a customer is classified as dangerous goods,Zhongshen completed the dangerous goods port entry declaration for Shanghai Port in advance,and the container pickup and warehousing arrangement were completed on the same day after the goods arrived at the port.

V.Foreign Exchange and Tax Refund Stage: Secure Receipt and Payment and Fast Arrival

The foreign exchange receipt and payment for raw plastic import shall comply with the requirements of the State Administration of Foreign Exchange for "receipt and payment under trade items",and customs declaration form,bill of lading and other materials shall be provided for foreign exchange settlement; for export tax refund (if export after processing is involved),special VAT invoices,tax refund copy of customs declaration form and other documents shall be prepared.The financial team of Zhongshen can quickly handle foreign exchange entry and settlement,and the preparation cycle of tax refund materials is controlled within 3 working days.Generally,the tax refund arrival time is 15-20 days,5 days faster than the industry average.

Summary: Zhongshen Helps Reduce Costs and Improve Efficiency for Raw Plastic Import
