Mastics; n.e.c. in heading no. 3214

HS code 321490 covers a diverse range of mastics, which are adhesive compounds used for sealing, filling, and bonding applications. These materials play a crucial role in various industries, from construction and automotive to aerospace and electronics. As a versatile and essential product, the global mastic market continues to grow, driven by increasing demand for durable and reliable sealing solutions across a wide range of end-use sectors.

Mastics are typically produced through a process of blending and compounding various raw materials, including resins, solvents, and fillers. The specific production techniques can vary depending on the desired properties and applications of the final product. Common methods include hot-melt extrusion, solvent-based mixing, and two-component systems that require on-site mixing before application.

The main inputs for the mastic industry include 390110 Polyethylene, having a specific gravity of less than 0.94, 390120 Polyethylene, having a specific gravity of 0.94 or more, 380620 Gum, wood or sulphate turpentine and other terpenic oils produced by the distillation or other treatment of coniferous woods; crude dipentene; sulphite turpentine and other crude para-cymene, and various mineral fillers and additives. Specialized equipment, such as mixing tanks, extruders, and application tools, are also essential for the production and use of mastics.

The primary outputs of the mastic industry are sealants, adhesives, and filler compounds used in a wide range of applications. These products are often consumed by industries such as 680911 Boards, sheets, panels, tiles and similar articles, of plaster or of compositions based on plaster, not ornamented, 870899 Parts and accessories for tractors, motor vehicles for the transport of ten or more persons, motor cars and other motor vehicles principally designed for the transport of persons, motor vehicles for the transport of goods and special purpose motor vehicles of headings 87.01 to 87.05, n.e.c. in this chapter, and 854420 Coaxial cable and other coaxial electric conductors, among others.
