Copper; wire, of copper-zinc base alloys (brass)

HS code 740821 covers the classification of copper wire made from copper-zinc base alloys, commonly known as brass. Brass is a versatile and widely used alloy that combines the desirable properties of copper and zinc, making it a popular choice for a variety of applications across numerous industries. This code is of significant importance in the global import/export trade, as copper and brass products are essential components in the manufacturing of a wide range of goods, from electrical and plumbing systems to decorative and architectural elements.

The production of copper wire under HS code 740821 typically involves a multi-step process. First, the copper and zinc are melted and alloyed together to create the desired brass composition. The molten alloy is then extruded or drawn through a die to form the wire, which is subsequently spooled or coiled for further processing or distribution. Depending on the intended application, the wire may undergo additional treatments, such as annealing, plating, or coating, to enhance its properties and performance.

The primary inputs required for the production of copper wire under HS code 740821 are copper and zinc, the two main components of brass. High-quality copper and zinc ores, as well as scrap metal, are essential raw materials. Additionally, specialized machinery, such as melting furnaces, extruders, and wire-drawing equipment, are necessary for the manufacturing process. Energy sources, such as electricity or natural gas, are also crucial inputs for the various stages of production.

The primary output of HS code 740821 is copper wire made from copper-zinc base alloys, or brass wire. This wire can be used in a wide range of applications, including 854411 Electric conductors, for a voltage not exceeding 1,000 V, fitted with connectors, 732690 Other articles of iron or steel, and 732410 Sinks and wash basins, of stainless steel. The versatility of brass wire makes it a valuable commodity in the global import/export trade, as it is a key component in the manufacturing of various products across multiple industries.
