(1) Classification of Plastics:

The Customs Tariff of the Peoples Republic of China divides plastics and their products into two sub-chapters:import and exporta. Primary forms of polymers (3901-3914);

b. Waste, semi-finished products, and finished products (3915-3926).
(2) Declaration Elements:

a. Primary forms of polymers: Product name, appearance, composition content, types and proportions of monomer units, etc.;

a. Primary forms of polymers: product name, appearance, composition content, types and proportions of monomer units, etc.;
b. Scrap materials: product name, source, composition, processing status, whether with core, etc.;
c. Semi-finished and finished products: product name, appearance, purpose, composition, material, accessories status, etc.

(1) Appearance:Describe the color, transparency, and shape of the product.
(2) Composition content:Types of substances in the product and their proportions.
(3) Types and proportions of monomer units:Specifically refers to low-molecular-weight compounds for polymerization or polycondensation.
(4) Base material source:Including recycled material, bottle flake material, virgin material, or sub-brand material.
(5) Brand:The brand name in Chinese or foreign language must be declared.
(6) Purpose:Describe the application aspects or scope of the product.
(7) Grade:Indicate whether the product meets preset production standards.
(8) Composite material status:Indicate whether it is compounded with other materials.
(9) Material:Types of materials or plastic varieties used in the product.
(10) Specifications and dimensions:Describe the size dimensions of the product.

(a) Appearance description is an essential element for HS codes 3901 to 3914 and cannot be omitted.
(b) "Composition content" and "types and proportions of monomer units" should be clearly distinguished.
(c) Base material source should be selected from the four provided options for declaration.
(d) Brand name should be declared in Chinese or foreign language.
(e) Material should be declared according to the actual product.
(f) The specifications and dimensions should be filled in according to the form of the goods, and should not be simply marked as "no specifications".

Note: To ensure the quality and safety of import and export goods, correct declaration is crucial. Enterprises must carefully verify and declare information to ensure its authenticity and accuracy.
