Polysulphides, polysulphones and similar products of chemical synthesis n.e.c. in chapter 39; in primary forms

HS code 391190 covers a diverse range of synthetic chemical products known as polysulphides, polysulphones, and similar compounds. These materials play a crucial role in various industries, from automotive and aerospace to electronics and construction. As versatile engineering plastics, they offer exceptional thermal and chemical resistance, making them indispensable in applications where durability and performance are paramount.

The production of polysulphides, polysulphones, and related products typically involves complex chemical synthesis processes. These often start with the reaction of organic compounds, such as phenols or aromatic amines, with sulfur-containing reagents. The resulting polymers are then further processed, often through extrusion or injection molding, to create the desired primary forms, such as pellets, sheets, or films.

The main inputs required for the production of HS code 391190 products include a range of organic chemicals, such as phenols, aromatic amines, and sulfur-containing compounds. Additionally, specialized catalysts, solvents, and other processing aids may be necessary. Manufacturers also rely on advanced production equipment, including reactors, extruders, and molding machines, to ensure consistent quality and efficiency.

The outputs of HS code 391190 are primarily used as engineering plastics in a wide range of applications. These materials may be further processed and incorporated into products classified under other HS codes, such as 392010 Plates, sheets, film, foil and strip, of polymers of ethylene, 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 392690 Other articles of plastics and articles of other materials of headings 39.01 to 39.14, n.e.c. in chapter 39.
