HS v2022 Code: 390761

About poly(ethylene terephthalate); in primary forms, having a viscosity of 78ml/g or higher

HS code 390761 covers poly(ethylene terephthalate) (PET) in its primary forms, specifically those with a viscosity of 78ml/g or higher. PET is a widely used thermoplastic polymer that has become an integral part of the global economy, with applications ranging from packaging and textiles to engineering plastics. This high-viscosity PET grade is particularly valued for its superior mechanical properties, chemical resistance, and thermal stability, making it a crucial material in various industries.

Production process

The production of high-viscosity PET (HS 390761) typically involves a multi-step process. First, ethylene glycol and terephthalic acid are combined through a polycondensation reaction to form PET resin. The resin is then extruded and pelletized into primary forms. To achieve the desired high viscosity, the PET may undergo additional processing steps, such as solid-state polymerization, which increases the molecular weight and enhances the material's properties.

Production inputs

The main inputs required for the production of high-viscosity PET (HS 390761) include ethylene glycol and terephthalic acid as the primary raw materials. Additionally, specialized machinery, such as extruders, pelletizers, and solid-state polymerization equipment, is necessary to manufacture the final product. Energy sources, such as electricity or natural gas, are also crucial inputs for the various stages of the production process.

Production outputs

The primary output of HS code 390761 is high-viscosity PET in its primary forms, such as pellets or granules. This material is widely used in the production of 392310 Boxes, cases, crates and similar articles of plastics for packaging applications, as well as in the manufacture of 550320 Synthetic filament tow for textile and apparel industries. Additionally, the high-viscosity PET may be further processed into engineering plastics for use in 392010 Other plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials and 392690 Other articles of plastics and articles of other materials of headings 39.01 to 39.14, n.e.s..
