Tungsten (wolfram); articles n.e.c. in heading no. 8101

HS code 810199 covers a diverse range of tungsten-based products, including raw tungsten materials, tungsten alloys, and various tungsten-containing articles. Tungsten is a highly versatile metal with exceptional hardness, high melting point, and excellent thermal and electrical conductivity. This industry plays a crucial role in supporting a wide array of industries, from construction and mining to electronics and aerospace, making it an integral part of the global economy.

The production of tungsten-based products under HS code 810199 typically involves several key steps. Tungsten ore is first mined and processed to extract pure tungsten powder. This powder is then compacted and sintered at high temperatures to form solid tungsten blocks or ingots. These raw tungsten materials can be further processed through techniques like rolling, forging, or machining to create a variety of tungsten-containing articles, such as wires, sheets, or specialized components.

The main inputs required for the production of tungsten-based products under HS code 810199 include tungsten ore, which is the primary raw material, as well as various alloying elements like cobalt, nickel, or iron, depending on the specific application. Specialized machinery and equipment, such as furnaces, rolling mills, and precision cutting tools, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in metallurgy, engineering, and advanced manufacturing techniques.

The outputs of the industry covered by HS code 810199 include a wide range of tungsten-based products, such as raw tungsten materials, tungsten alloys, and various tungsten-containing articles. These outputs are then consumed by a diverse array of industries, including 820713 Machine tools for working metal, 840290 Parts of steam or other vapor generating boilers, 840490 Parts of machinery and apparatus for the industrial preparation or manufacture of food or drink, and 901380 Optical devices, appliances and instruments, n.e.c. in this chapter; parts and accessories thereof.
