HS v2022 Code: 740322

About copper; copper-tin base alloys (bronze) unwrought

HS code 740322 covers the import and export of unwrought copper and copper-tin base alloys, commonly known as bronze. This industry plays a crucial role in the global metal manufacturing and construction sectors, providing essential raw materials for a wide range of applications. As a highly versatile and durable metal, copper and its alloys are in high demand across various industries, making this code an important component of the broader international trade landscape.

Production process

The production of unwrought copper and copper-tin alloys typically involves a multi-step process. First, copper ore is extracted from mines and then smelted to produce pure copper. The copper is then alloyed with tin to create bronze, which can be cast or extruded into various shapes and forms. Depending on the specific application, the alloy composition may be adjusted to achieve desired properties, such as increased strength or corrosion resistance.

Production inputs

The main inputs required for the production of unwrought copper and copper-tin alloys include copper ore, tin, and various energy sources for smelting and casting processes. Additionally, specialized machinery and equipment, such as furnaces, molds, and extrusion presses, are essential for the manufacturing of these metal products. The availability and cost of these raw materials and production resources can significantly impact the global supply and pricing of 740322 (copper; copper-tin base alloys (bronze) unwrought).

Production outputs

The primary outputs of HS code 740322 are unwrought copper and copper-tin alloy (bronze) products, which can be used in a wide range of applications. These include construction materials, such as pipes, fittings, and roofing components, as well as electrical and electronic components, industrial machinery, and various consumer goods. The outputs of this industry are often consumed by other industries covered under codes such as 7403 copper, refined and copper alloys, unwrought, 7404 copper waste and scrap, and 7407 copper bars, rods and profiles.
