About copper; plates and sheets, of a thickness exceeding 0.15mm, of copper-zinc base alloys (brass), not in coils

HS code 740929 covers the trade of copper plates and sheets made from copper-zinc base alloys, commonly known as brass. This industry plays a crucial role in the broader metal manufacturing and construction sectors, providing essential raw materials for a wide range of applications. Brass, with its distinctive golden hue and desirable properties such as corrosion resistance and malleability, is a versatile alloy that finds use in a variety of products, from plumbing fixtures to decorative architectural elements.

Production process

The production of copper plates and sheets under HS code 740929 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 cast into ingots or billets, which are subsequently rolled or extruded into the desired thickness and shape of the plates and sheets. Precision temperature and pressure controls are essential during these metalworking stages to ensure the final products meet strict quality standards.

Production inputs

The main inputs required for the production of copper plates and sheets under HS code 740929 include refined copper, zinc, and various alloying elements such as lead or tin. Specialized metalworking machinery, including rolling mills, extruders, and annealing furnaces, are also crucial for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in metallurgy, metalworking, and quality control.

Production outputs

The copper plates and sheets produced under HS code 740929 are primarily used as raw materials in the manufacturing of a wide range of products. These include 732510 Sanitary ware and parts thereof, of copper, 732690 Other articles of copper, n.e.s., and 731815 (Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter-pins, washers (including spring washers) of copper). The industry's output also serves as an important input for the construction and building materials sectors, where brass components are used in plumbing, roofing, and decorative applications.
