Plastics; builders' ware, doors, windows and their frames and thresholds for doors

HS code 392520 covers a diverse range of plastic building materials, including doors, windows, and their associated frames and thresholds. This industry plays a crucial role in the construction and renovation sectors, providing essential components that contribute to the structural integrity, energy efficiency, and aesthetic appeal of buildings. As a key part of the broader plastics manufacturing industry, this code represents a significant economic activity with applications across residential, commercial, and industrial construction projects.

The production of the items covered under HS code 392520 typically involves a combination of extrusion, injection molding, and thermoforming techniques. Extruded plastic profiles are used to create door and window frames, while injection molding is employed to manufacture more complex components, such as hinges, locks, and thresholds. Thermoforming processes may be utilized to shape and mold plastic sheets into specific door and window designs.

The main inputs required for the production of items under HS code 392520 include various types of thermoplastic resins, such as polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP). These raw materials are supplemented by additives, such as stabilizers, plasticizers, and colorants, which enhance the physical properties and appearance of the final products. Additionally, the industry relies on specialized machinery, molds, and tooling to facilitate the manufacturing processes.

The primary outputs of the industry covered by HS code 392520 are plastic doors, windows, and their associated frames and thresholds. These products are widely used in the construction and renovation of residential, commercial, and industrial buildings. The outputs of this industry may be consumed by other industries, such as 441820 Wood; windows, French-windows and their frames, 441910 Wood; doors and their frames and thresholds, and 681011 Cement; building blocks and bricks, as they are often integrated into larger construction projects.
