HS v2022 Code: 3907

About polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms

HS code 3907 covers a diverse range of synthetic polymers that are widely used in various industries. These materials, including polyacetals, polyethers, epoxide resins, polycarbonates, alkyd resins, and polyesters, are essential building blocks for a vast array of products, from automotive components to packaging materials. This industry plays a crucial role in the global economy, providing critical inputs to numerous downstream sectors and contributing to the development of innovative, high-performance materials.

Production process

The production of the materials covered under HS code 3907 typically involves complex chemical synthesis processes. Polyacetals, for example, are commonly produced through the polymerization of formaldehyde, while polyethers are often synthesized by the reaction of epoxides with alcohols or other nucleophiles. Epoxide resins are typically formed by the reaction of epichlorohydrin with bisphenol A, and polycarbonates are produced by the reaction of phosgene with bisphenol A. These production methods require specialized equipment, precise control of reaction conditions, and careful handling of hazardous materials.

Production inputs

The main inputs required for the production of the materials under HS code 3907 include a variety of petrochemical feedstocks, such as ethylene, propylene, and benzene, as well as specialty chemicals like formaldehyde, epichlorohydrin, and bisphenol A. Additionally, the industry relies on advanced manufacturing equipment, including reactors, distillation columns, and extrusion machinery, as well as a skilled workforce with expertise in polymer chemistry and engineering.

Production outputs

The materials produced under HS code 3907 are widely used as inputs for a diverse range of downstream industries. Polyacetals, for instance, are commonly used in the production of 3926 Articles of plastics and articles of other materials of headings 3901 to 3914, such as automotive parts and electrical components. Polyethers and epoxide resins are key components in 3907 Polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms and 3909 Amino-resins, phenolic resins and polyurethanes, in primary forms, which are used in coatings, adhesives, and composite materials. Polycarbonates are widely used in the production of 3926 Articles of plastics and articles of other materials of headings 3901 to 3914, such as eyewear, electronics, and construction materials.
