About copper; strip, of a thickness exceeding 0.15mm, of copper-tin base alloys (bronze), in coils

HS code 740931 covers the classification of copper strip made from copper-tin base alloys, commonly known as bronze. This industry plays a crucial role in the broader metal manufacturing and fabrication sectors, providing essential raw materials and components for a wide range of applications across various industries. The production and trade of these copper-tin alloy strips are integral to the global supply chain, supporting the development of products ranging from electrical and electronic devices to construction materials and decorative items.

Production process

The production of copper-tin alloy strips classified under HS code 740931 typically involves a multi-step process. The raw materials, including copper and tin, are first melted and alloyed to create the desired bronze composition. The molten alloy is then cast into ingots or billets, which are subsequently rolled or drawn into thin strips with a thickness exceeding 0.15mm. The strips may undergo further processing, such as annealing or surface treatment, to enhance their physical and mechanical properties before being coiled and prepared for distribution.

Production inputs

The primary inputs required for the production of copper-tin alloy strips under HS code 740931 are copper and tin. High-purity copper and tin are essential raw materials, along with various alloying elements and additives that may be used to fine-tune the properties of the final product. Additionally, the industry relies on specialized rolling and drawing equipment, as well as energy sources and skilled labor to carry out the manufacturing processes.

Production outputs

The copper-tin alloy strips classified under HS code 740931 are versatile materials with a wide range of applications. They are commonly used in the production of electrical and electronic components, such as 854411 winding wire, 854420 coaxial cable, and 853400 printed circuits. These strips also find applications in the construction industry, where they are used for roofing, flashing, and decorative elements. Furthermore, the output of this industry may be consumed by manufacturers of 732393 copper tableware and kitchenware and 830630 statuettes and other ornamental copper articles.
