HS v2017 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 primary forms, 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, particularly in the packaging, textile, and electronics industries. Its versatility, durability, and recyclability have made it a popular choice for a wide range of applications, contributing to its significant role in international trade and commerce.

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 required viscosity of 78ml/g or higher, the PET may undergo additional processing steps, such as solid-state polymerization, which increases the molecular weight and, consequently, the viscosity of the material.

Production inputs

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

Production outputs

The primary output of HS code 390761 is high-viscosity PET in primary forms, which can be used in a variety of applications. This material is often consumed by industries producing 392310 Boxes, cases, crates and similar articles, of plastics for packaging, 550320 Synthetic filament tow for textile manufacturing, and 854420 Coaxial cable and other coaxial electric conductors for the electronics industry, among others. The high-viscosity PET produced under this code is valued for its enhanced mechanical properties, thermal stability, and chemical resistance compared to lower-viscosity PET.
