Import of Recycled Plastic Granules Customs Clearance Process and 2026 Regulatory Requirements: Compliance Pitfall Avoidance to Reduce Port Detention Costs

Core Regulatory Requirements for Import of Recycled Plastic Granules (Latest Version 2026)

In 2026,the General Administration of Customs updated the "Regulatory Details for Import of Recycled Plastic Granules".The core determination criteria are still based on the "three unifications",namely uniform color,uniform particle size,and uniform packaging.However,new regulations have been added,such as impurity content not exceeding 0.5% and VOC emission limits complying with GB38507-2020.Goods that do not meet the standards will be directly judged as solid waste and subject to return or destruction.There are significant differences in regulatory requirements for imported recycled plastic granules from different regions of origin; refer to the table below for details.

Many enterprises easily overlook regulatory differences based on origin when importing.For example,recycled plastic granules imported from Southeast Asia without an RCEP Certificate of Origin obtained in advance will lead to an additional 3% tariff payment.If PP recycled plastic granules imported from the USA fail to check the anti-dumping duty schedule in advance,upon arrival,they will find that an anti-dumping duty of 42% needs to be paid,directly increasing the cargo value by nearly half.

Core Operation Nodes of Import Agency for Recycled Plastic Granules

In March 2026,I met Mr.Gan from Ningbo,Zhejiang,who runs an injection molding business for home appliance housings.He imported 12 containers of PE recycled plastic granules from Malaysia and declared them through a local customs broker.Due to the lack of pre-inspection for solid waste,his goods were selected for on-site identification.Among them,2 containers were judged as solid waste and required to be returned because they were mixed with 5% of different-colored granules.The remaining 10 containers were detained at the port for 21 days,with detention and storage costs amounting to RMB 120,000.Later,he entrusted our agency to handle subsequent import business.We contacted the Malaysian supplier before shipment,guided them to sort the granules in accordance with domestic identification standards,and issued a third-party pre-inspection report in advance.We submitted pre-examination materials simultaneously during customs declaration.The subsequent 8 containers of goods were declared at Yangshan Port,Shanghai,taking only 3 days from arrival to release without being subject to controlled inspection.The cost per container was nearly RMB 2,000 lower than before.

There are four core operation nodes for importing recycled plastic granules; proper preparation in advance can avoid over 90% of customs clearance risks.

• Accurate HS Code Classification: Strictly classify according to the corresponding tariff item in Chapter 39 of the 2026 Edition of the Customs Import and Export Tariff to avoid misclassification into the solid waste category leading to direct return.The tariff difference between different categories of recycled plastic granules can reach up to 10%,and accurate classification can directly reduce tariff costs.
• Pre-examination of Documents in Advance: Coordinate with overseas suppliers before shipment to collect documents such as MSDS,factory test reports,packaging declarations,and Certificates of Origin.Verify the "three unifications" supporting materials in advance to avoid port detention due to incomplete documents upon arrival.
• Pre-inspection for Solid Waste Attributes: Coordinate with a third-party testing institution in advance to complete pre-inspection in accordance with the latest 2026 "Solid Waste Identification Standards for Recycled Plastic Granules" and issue a pre-identification report,which can reduce the probability of solid waste controlled inspection by over 90%.
• Pre-verification of Customs Valuation: Prepare procurement contracts,foreign exchange payment vouchers,overseas factory invoices,and reference materials for imported prices of the same category in advance.This allows quick submission of supporting documents when facing valuation inquiries,avoiding additional tax and late payment interest losses.

Common Risks and Pitfall Avoidance Guide for Import of Recycled Plastic Granules

Most risks related to importing recycled plastic granules can be predicted in advance.Many enterprises fall into pitfalls because they only focus on cargo value costs while ignoring compliance costs.Three common types of risks need key attention:

The first is the risk of return due to solid waste.In 2026,the customs updated the control model for recycled plastic granules.As long as the declared recycled plastic granules have a color difference exceeding 10%,particle size difference exceeding 20%,or mixed with other impurities,the solid waste identification instruction will be automatically triggered.Once judged as solid waste,the return cost can exceed 30% of the cargo value,and the enterprise will be included in the customs dishonesty list,leading to all subsequent imports being controlled.

The second is the risk of additional tax payment due to valuation.In 2026,the customs updated nearly 30,000 global procurement price data entries in the valuation database for recycled plastic granules.If the declared price is underreported by more than 5%,a valuation early warning will be automatically triggered.The total of additional tax and late payment interest can reach up to 20% of the cargo value.Many enterprises underreport prices to reduce costs,but eventually lose more.

The third is the risk of hidden costs.Many enterprises are unfamiliar with the operational rhythm of ports.For example,during Ramadan in Southeast Asia,the operational efficiency of local ports drops by 40%.Before the Christmas season in Europe and the USA,the inspection volume at domestic ports increases by 30%.If the declaration time is not arranged in advance,it is easy to incur detention fees,order exchange fees,and overdue penalties.Many freight forwarders will not inform of these costs in advance,so enterprises have to bear them finally.

Core Value of Agency Services

Zhongshitong is headquartered in Shanghai,relying on the customs clearance resource advantages of Shanghai port to realize remote declaration at all ports nationwide.We have cooperative agency outlets in over 20 countries globally,and can coordinate with overseas suppliers in advance to complete document review and cargo pre-inspection.For goods from RCEP member states,we verify Certificates of Origin in advance to ensure enjoying tariff reductions.For categories with anti-dumping duties in Europe and the USA,we can provide compliant origin traceability solutions to avoid paying high anti-dumping duties.

Many enterprises think that self-declaration can save costs,but in reality,if they are not familiar with regulatory rules,the cost of a single return or additional tax payment is enough to pay for agency service fees for several years.Professional import agencies can intervene in risk investigation from before shipment,control each operation node throughout the process,not only accelerate customs clearance speed but also avoid all predictable risks in advance.The actual comprehensive cost is 20%-30% lower than self-declaration.

When choosing an agency for importing recycled plastic granules,do not only look at the quote.Priority should be given to confirming whether the agency has operation experience in similar products,can provide a clear risk prediction plan,and can coordinate with overseas parties to complete pre-inspection.Avoid choosing an agency only responsible for declaration after arrival; if the previous risks are not investigated,enterprises will have to bear all subsequent problems themselves.
