2026 PS Plastic Pellets Import Customs Clearance Operation Guide

Core Regulatory Requirements for PS Plastic Pellets Import Customs Clearance in 2026

PS plastic pellets fall under the category of general chemical products under Chapter 3903.In 2026,the General Administration of Customs adjusted declaration rules for plastic pellet products,adding two mandatory declaration elements: recycled attribute and monomer unit content.Omission or incorrect entry directly triggers inspection control.I previously worked with Mr.Tang from Suzhou,who imported food-contact grade PS plastic pellets from South Korea.He failed to indicate the "non-recycled" attribute during declaration,leading to the cargo being selected by Customs for third-party testing.This resulted in 12 days of port detention and RMB 23,000 in demurrage fees.After our intervention,we supplemented the original factory test report and production process description,achieving release within 3 days.

Import duties,taxes,and regulatory requirements for PS plastic pellets vary significantly depending on the origin.The latest rules for 2026 are summarized below:

Key Practical Points for the Entire PS Plastic Pellets Import Clearance Process

• Pre-Declaration Document Review: Collect MSDS,packing list,commercial invoice,trade contract,and Certificate of Origin 3 days in advance.Focus on verifying consistency between declared elements and physical labels.The margin of error for the four key pieces of information—brand,model,material,and specification—must not exceed 0.5%,otherwise it will directly trigger valuation queries.
• Accurate HS Code Classification: General non-foam PS plastic pellets are classified under 39031100; foam-grade under 39031910.Food-contact grade requires additional test reports such as FDA or GB4806.7.Recycled material is classified under 39039000 and must comply with the latest 2026 standards for solid waste import.Non-compliance leads directly to re-export handling.
• Valuation Risk Pre-assessment: In 2026,Customs’ valuation benchmark for PS plastic pellets is within ±5% of the CIF price from Southeast Asia in the previous month. For declared prices deviating from this range,prepare supporting documents in advance,such as payment proof,original factory invoice,and trade correspondence,to avoid Customs valuation and tax supplements.
• Pre-Inspection Preparation: Shanghai Port launched a pre-inspection service for chemical products in 2026.We can schedule Customs officers for a pre-inspection at the warehouse to confirm non-hazardous status and absence of solid waste risks before formal declaration,potentially reducing the inspection rate by 70%.

Common Risks and Avoidance Solutions for PS Plastic Pellets Import Clearance

The first is the D/O fee trap: Many appointed freight forwarders charge an additional RMB 300-800 as "document processing fees" or "hazardous goods identification fees" after cargo arrival.In reality,PS plastic pellets are general cargo.As long as an MSDS proving non-hazardous status is provided,no extra hazardous goods identification is needed.We have long-term cooperation with agents in over 200 ports worldwide.All charges at the D/O exchange stage are disclosed upfront,with no hidden fees.

The second is the risk of forged Certificates of Origin: To avoid anti-dumping duties on PS plastic pellets from Europe and the US,some companies ship goods to Southeast Asia for transshipment and forge local Certificates of Origin to apply for zero tariffs.In 2026,Customs has implemented a Certificate of Origin traceability system.If abnormal logistics paths are detected,they will directly demand payment of anti-dumping duties plus a fine of 0.5 to 3 times the duty amount.Our risk control system pre-checks the entire logistics chain and provides compliant tax planning solutions,absolutely avoiding regulatory red lines.

The third is foreign exchange loss risk: In 2026,the two-way fluctuation of the RMB exchange rate has increased.If the interval between booking and payment exceeds 15 days,a 2-3% exchange loss may occur.We offer foreign exchange locking services to lock in the purchase rate in advance,avoiding extra costs from exchange rate fluctuations.
