Chapter 39 covers plastics and articles thereof, including polymers in primary forms, synthetic resins, plastic materials (such as plates, sheets, film, foil, strips, etc.) and articles of plastics. This chapter is subdivided based on the chemical composition, processing state, and use of polymers, and is the core chapter for classifying plastic products in international trade. Heading 3920 covers other plates, sheets, film, foil and strip, of non-cellular plastics, not reinforced, laminated, or combined with other materials. This heading is further subdivided based on the type of plastic material (such as polyethylene, polypropylene, polyamide, etc.), and is an important classification node for plastic semi-finished products. First 2 digits 39: indicates Chapter 39 plastics and articles thereof, covering all plastic materials and their primary articles. Digits 3-4, 20: indicates heading 3920, i.e., other plates, sheets, film, foil and strip, of non-cellular plastics, not reinforced, laminated, or combined. Digits 5-6, 92: indicates subheading 3920.92, specifically plates, sheets, film, foil of polyamides (nylon), distinguished from other plastic materials such as polyethylene and polypropylene. This product is plates, sheets, film, foil of polyamide, belonging to semi-finished products of non-cellular plastics, and is not reinforced or laminated with other materials, therefore classified under 3920. Since the material is polyamide, it is classified under subheading 3920.92, rather than other plastic subheadings (such as 3920.10 polyethylene).

📝 Declaration Elements
Product name: The specific name of the declared commodity, which should accurately reflect the material and form, such as "polyamide film". Material: Clearly specify the type of polyamide, such as nylon 6, nylon 66, etc., and whether additives are contained. Appearance: Describe the shape (plate, sheet, film, foil), color, transparency, dimensions, etc. Whether cellular: Declare whether it is cellular plastic; cellular plastics are classified under 3921, non-cellular under 3920. Whether reinforced or laminated: Declare whether it is reinforced, laminated, or supported with other materials; if not, classified under 3920. Use: Explain the main use, such as packaging, electronic insulation, automotive parts, etc. Specifications and dimensions: Provide thickness, width, length, etc., to distinguish plates, sheets, film, foil. Product name: Polyamide film; Material: Nylon 6, without plasticizer; Appearance: transparent roll, thickness 0.05mm, width 1000mm; Whether cellular: non-cellular; Whether reinforced or laminated: not reinforced, not laminated; Use: for food packaging; Specifications and dimensions: thickness 0.05mm, width 1000mm, length 5000m/roll. Mistakenly classifying cellular polyamide under 3920, when it should actually be classified under 3921. Failing to distinguish polyamide from other plastics, leading to incorrect subheading. Ignoring reinforcement or lamination, incorrectly classifying under 3920.
Product name
The specific name of the declared commodity, which should accurately reflect the material and form, such as "polyamide film".
⚠️ Incorrectly declared as "plastic film" without specifying polyamide material.
Material
Clearly specify the type of polyamide, such as nylon 6, nylon 66, etc., and whether additives are contained.
⚠️ Only writing "nylon" without distinguishing specific models or copolymers.
Appearance
Describe the shape (plate, sheet, film, foil), color, transparency, dimensions, etc.
⚠️ Omitting dimensions or thickness, leading to classification disputes.
Whether cellular
Declare whether it is cellular plastic; cellular plastics are classified under 3921, non-cellular under 3920.
⚠️ Mistakenly declaring microcellular foamed materials as non-cellular.
Whether reinforced or laminated
Declare whether it is reinforced, laminated, or supported with other materials; if not, classified under 3920.
⚠️ Failing to declare combination with glass fiber, etc., leading to incorrect classification under 3920.
Use
Explain the main use, such as packaging, electronic insulation, automotive parts, etc.
⚠️ Use description too general, such as "industrial use".
Specifications and dimensions
Provide thickness, width, length, etc., to distinguish plates, sheets, film, foil.
⚠️ Failing to provide thickness, making it impossible to determine whether it belongs to film.
Example： Product name: Polyamide film; Material: Nylon 6, without plasticizer; Appearance: transparent roll, thickness 0.05mm, width 1000mm; Whether cellular: non-cellular; Whether reinforced or laminated: not reinforced, not laminated; Use: for food packaging; Specifications and dimensions: thickness 0.05mm, width 1000mm, length 5000m/roll.
Common Mistakes：
Mistakenly classifying cellular polyamide under 3920, when it should actually be classified under 3921.
Failing to distinguish polyamide from other plastics, leading to incorrect subheading.
Ignoring reinforcement or lamination, incorrectly classifying under 3920.
🎯 Classification Logic
Classification basis: First determine whether it is plastic (Chapter 39), then determine whether it is non-cellular plastic plates, sheets, film, foil (3920), and finally determine the subheading based on the type of plastic. Plates, sheets, film, foil made of polyamide and not reinforced, laminated, or combined are classified under 3920.92. 3921.90 Other plastic plates, sheets, film, foil: 3921 is cellular plastic or reinforced, laminated, combined plastic plates, sheets, film, foil, while 3920 is non-cellular and not reinforced or laminated. 3920.10 Plates, sheets, film, foil of polyethylene: Different material; 3920.10 is polyethylene, 3920.92 is polyamide. 3920.20 Plates, sheets, film, foil of polypropylene: Different material; 3920.20 is polypropylene, 3920.92 is polyamide. 5903.20 Textile fabrics coated with polyamide: 5903 is textile combined with plastic, 3920 is pure plastic plates, sheets, film, foil. Is it indeed polyamide material? Is it non-cellular plastic? Is it not reinforced, laminated, or combined? Does it belong to the form of plates, sheets, film, foil? Is it not combined with other materials?
