Propylene, other olefin polymers; n.e.c. in heading no. 3902, in primary forms

HS code 390290 covers a diverse range of propylene and other olefin polymers that are not classified elsewhere in the 3902 heading. These polymers are essential materials in the plastics industry, finding widespread applications across various sectors, including packaging, automotive, construction, and consumer goods. As a key component of the global petrochemical supply chain, the production and trade of these polymers play a vital role in supporting economic growth and development worldwide.

The primary production techniques for the polymers covered under HS code 390290 involve polymerization processes, such as catalytic polymerization, using a range of catalysts and reaction conditions. These processes typically start with the monomer feedstock, which is then converted into the desired polymer through carefully controlled temperature, pressure, and other parameters. The resulting polymer is then extruded, pelletized, or otherwise processed into primary forms, such as granules, powders, or blocks, ready for further downstream processing and manufacturing.

The main inputs required for the production of the polymers under HS code 390290 include the monomer feedstock, typically propylene or other olefins, as well as various catalysts, additives, and processing equipment. The availability and cost of the monomer feedstock, often derived from the 270900 Petroleum oils and oils obtained from bituminous minerals, crude industry, are crucial factors in the competitiveness and profitability of this industry. Additionally, specialized manufacturing equipment, such as polymerization reactors, extruders, and pelletizers, are essential capital investments for producers.

The primary outputs of the industry covered by HS code 390290 are the various propylene and other olefin polymers in their primary forms, such as granules, powders, or blocks. These polymers are then consumed by a wide range of downstream industries, including 392010 Plates, sheets, film, foil and strip, of polymers of ethylene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392020 Plates, sheets, film, foil and strip, of polymers of propylene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392030 Plates, sheets, film, foil and strip, of polymers of styrene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, and 392040 Plates, sheets, film, foil and strip, of polymers of vinyl chloride, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, among others.
