Polyesters; n.e.c. in heading no. 3907, saturated, in primary forms

HS v2017 Code: 390799

About polyesters; n.e.c. in heading no. 3907, saturated, in primary forms

HS code 390799 covers a diverse range of saturated polyester products in primary forms, excluding those more specifically classified elsewhere. These polyesters have a wide array of applications across various industries, making them an essential component of the global economy. They are utilized in the production of textiles, packaging materials, automotive parts, and a multitude of other consumer and industrial goods.

Production process

The production of polyesters classified under HS code 390799 typically involves the polycondensation of dicarboxylic acids and dihydric alcohols. This process results in the formation of long-chain polymer molecules with a high degree of saturation. The specific techniques employed may vary depending on the desired properties and end-use applications of the polyester products.

Production inputs

The main inputs required for the production of polyesters under HS code 390799 include petrochemical-derived raw materials such as 290711 ethylene glycol, 291712 terephthalic acid, and other dicarboxylic acids and dihydric alcohols. Additionally, specialized catalysts, stabilizers, and other additives may be used to enhance the performance characteristics of the final polyester products.

Production outputs

Polyesters classified under HS code 390799 are widely used in the manufacture of a diverse range of products, including 540233 polyester textiles, 392010 polyester film and sheets, and 870321 polyester-based automotive components. These polyesters may also serve as inputs for the production of other 3907 polyester-based products not specifically covered by this code.
