Poly(ethylene terephthalate); in primary forms, having a viscosity of less than 78ml/g

HS v2022 Code: 390769

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

HS code 390769 covers poly(ethylene terephthalate) (PET) in primary forms, with a viscosity of less than 78ml/g. PET is a widely used thermoplastic polymer that has become an essential material in various industries, from packaging and textiles to electronics and construction. Its versatility, durability, and recyclability have made it a staple in the global economy, contributing significantly to international trade and the broader manufacturing sector.

Production process

The production of PET with a viscosity of less than 78ml/g 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, such as chips or granules. To achieve the desired viscosity, the PET may undergo further processing, such as solid-state polymerization or melt-phase polymerization, to control the molecular weight and chain length.

Production inputs

The main inputs required for the production of HS code 390769 PET include ethylene glycol and terephthalic acid as the primary raw materials. Additionally, the process may require specialized machinery, such as extruders, reactors, and pelletizers, as well as energy sources, catalysts, and other additives to ensure the desired properties and quality of the final product.

Production outputs

The primary output of HS code 390769 is PET in various primary forms, such as chips, granules, or pellets. These PET products can be further processed and consumed by a wide range of industries, including 392310 Boxes, cases, crates and similar articles, of plastics, 392330 Carboys, bottles, flasks and similar articles, of plastics, 540233 Polyester filament yarn, including monofilament; not put up for retail sale, and 854420 Coaxial cable and other coaxial electric conductors, among others.
