Practical Guide on Customs Valuation and Commodity Inspection for Shanghai Plastic Pellet Import Agencies

Plastic Pellet Import Agency: Core Risks and Countermeasures for Customs Valuation

Plastic pellet import agencies first face the customs valuation process.Last year,Mr.Jia from a chemical enterprise imported PP plastic pellets from Singapore.The declared price on the customs declaration was 12% lower than the average price in the customs internal database,which directly triggered a customs inspection.Such cases are not uncommon in 2026,as plastic pellets have frequent HS code classification disputes and the international market price fluctuates significantly.

Three Major Dispute Points in Customs Valuation

• Price Declaration Disputes: Customs will verify whether the transaction price meets normal trade conditions.For example,if an importer quotes under EXW terms,additional documents such as factory pickup records and international logistics cost vouchers must be provided; otherwise,the declared price may be deemed "too low".
• Classification Disputes: For polyethylene pellets,the tax rate for general grade (39011000,density 0.92-0.96) differs by 3% from that for high-density grade (39012000).Agencies must confirm the final use with the customs broker in advance to avoid tax supplements due to classification errors.
• Rules of Origin: Plastic pellets imported from RCEP member states are eligible for tariff reductions,but the "origin criteria" (e.g.fully obtained,tariff classification change) must be indicated on the customs declaration.A client once paid an extra 23,000 yuan in tariffs for plastic pellets imported from South Korea due to missing the origin certificate version number.

Impact of 2026 Customs Valuation New Rules on Plastic Pellet Imports

According to Announcement No.15 of the General Administration of Customs,2026,plastic pellet imports require submission of an "Explanation of Price-influencing Factors",focusing on: ① Production process (e.g.cost differences between drawing grade and injection molding grade); ② Transit loss rate (1.5%-2% is common for sea transport); ③ International market price fluctuation range (import average price data released by the General Administration of Customs in the past 3 months must be provided).

Commodity Inspection Pre-review and MSDS Compliance: First Pitfall Avoidance Step for Plastic Pellet Import Agencies

Plastic pellets are classified as chemical products,so commodity inspection pre-review is a core competency of agencies.Mr.Hua from a chemical enterprise once failed to clear customs after goods arrived at the port due to not submitting MSDS documents in advance,resulting in 18,000 yuan in costs from 3 days of port detention.This is also one of the "false declaration of non-hazardous chemicals" behaviors that customs will focus on verifying in 2026.

Three-review Principles for MSDS Documents

• Review against Producing Country Standards: The EU REACH Regulation requires MSDS to include 13 items,while US OSHA requires 29 items.If the MSDS provided by the importer only meets Chinese standards,it may be rejected due to missing items such as "carcinogenicity classification" and "heavy metal content".
• Consistency of Chinese Version: The 2026 new commodity inspection system requires the Chinese version of MSDS to fully correspond to the version from the producing country.An agency once had goods detained due to translating "CAS Number" into "Product Code" incorrectly.
• GHS Label Matching Degree: Both Chinese and English GHS labels must be affixed to plastic pellet packaging.Mislabeling of identifiers such as "Flammable Solid (Category 4)" or "Irritant (Category 3)" will trigger penalties from the commodity inspection bureau for "non-compliant packaging labels".

Legal Red Lines for Non-hazardous Chemical Declaration

Announcement No.8 of the General Administration of Customs,2026 clearly states: If plastic pellets contain free monomers (e.g.styrene > 0.5%) or heavy metals (e.g.lead > 100ppm),even if the MSDS marks them as "non-hazardous",they must be declared as "hazardous chemicals".An agency once assisted a client in declaring styrene-containing plastic pellets as general cargo,resulting in goods being detained by customs and a fine of 50,000 yuan.

Import Licenses and Anti-dumping Duties: Policy Interpretation by Shanghai Port Agencies

The Automatic Import License (HS Codes Added in 2026: 39011000-39021000) is a key document for plastic pellet imports.Notes: ① The license is valid for 6 months; re-application is required if expired; ② An "Import Purpose Statement" (e.g.for injection molding/drawing) must be submitted when applying; re-filing is required if the purpose changes.

Anti-dumping Duties and Tariff Inquiry Tools

In 2026,the EU imposes anti-dumping duties of 12.8%-43.2% on Chinese PP plastic pellets,and the US imposes an additional 21.5% tariff on PS plastic pellets.Agencies must inquire about real-time tariff rates through the official website of the Bureau of Fair Trade for Imports and Exports,Ministry of Commerce,and clarify the "party responsible for tariff adjustment risks" in the contract in advance.

Origin Certificate Pre-review Checklist

• Origin Certificate (Form A/R) must be submitted 72 hours before shipment to ensure consistency of "transport route" and "production batch" with the customs declaration
• Additional "Product Composition List" (e.g.polyethylene content > 90%) is required for imports from RCEP member states such as South Korea and Japan
• A "Non-GMO Declaration" must be supplemented for plastic pellets imported from Australia (applicable to food-contact grade plastics)

Logistics and Capital Risk Control: Guide to Avoiding Hidden Costs Such as Demurrage Fees and Document Exchange Fees

Zhongshitong’s 20 years of agency experience shows that hidden costs account for 15%-20% of the total cost of plastic pellet imports.Below are high-frequency risk points and corresponding solutions:

Three Scenarios Leading to Demurrage Fees

Identifying Document Exchange Fee Traps

Document exchange fees usually include "Bill of Lading Exchange Fee" (150-300 yuan per shipment),"Telex Release Fee" (200-500 yuan per shipment),and "Port Storage Fee" (50-100 yuan per day).An agency once discovered that shipping lines increased fees indirectly through "Amendment Fees"; it is necessary to sign an "All-inclusive Fee Agreement" with the shipping agent in advance.

Practical Case: Full Process Review of Plastic Pellet Import Customs Clearance for a Chemical Enterprise

Scenario: Mr.Jia from a chemical enterprise imported 500 tons of PP plastic pellets (HS Code 39021000) from Malaysia,with an FOB price of USD 1,200 per ton and destination port Shanghai Port.

Task: Zhongshitong Agency must complete the following before the goods arrive at the port: ① MSDS pre-review; ② Automatic Import License application; ③ Origin certificate verification.

Actions: ① Within 48 hours of receiving the documents,it was found that the MSDS lacked the "GHS Label",and the overseas supplier was immediately contacted to re-send it; ② Since Malaysia is an RCEP member state,Form R origin certificate was applied for 72 hours in advance; ③ Coordinated with the customs broker to complete "pre-classification determination",confirming a 0 tax rate (no additional anti-dumping duty).

Result: The goods were released within 24 hours of arriving at the port,shortening the customs clearance time by 48 hours compared to the industry average,saving 62,000 yuan in demurrage fees and enjoying 125,000 yuan in tariff reduction.
