HS v2017 Code: 392111

About plastics; plates, sheets, film, foil and strip, of polymers of styrene, cellular

HS code 392111 covers cellular plastics products made from polymers of styrene. These lightweight, insulating materials are widely used in packaging, construction, and a variety of other applications. As a key component of the broader plastics industry, this sector plays an important role in the global economy, supporting manufacturing, trade, and consumer needs across numerous industries.

Production process

The production of cellular styrene polymers typically involves the expansion of polystyrene beads or sheets through the application of heat and pressure. This process creates a porous, lightweight material with excellent insulating properties. Manufacturers may also utilize injection molding or extrusion techniques to shape the material into the desired plates, sheets, films, foils, or strips.

Production inputs

The primary raw material input for this industry is polystyrene resin. Manufacturers also require access to specialized production equipment, such as molding machines, extruders, and cutting/shaping tools. Energy sources, such as electricity or natural gas, are necessary to power the production process, while chemical additives may be used to modify the material's properties as needed.

Production outputs

The cellular styrene polymer products covered by HS code 392111 are widely used in packaging, insulation, and a variety of other applications. These outputs may be further processed or consumed by industries covered under related HS codes, such as 392110 Plastics; plates, sheets, film, foil and strip, of polymers of styrene, non-cellular and 392190 Plastics; plates, sheets, film, foil and strip, of other plastics, cellular.
