HS v2017 Code: 740931

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 (also known as bronze), with a thickness exceeding 0.15mm, and presented in coils. This industry plays a crucial role in the broader metal manufacturing and fabrication sectors, providing essential raw materials and semi-finished products for a wide range of applications across various industries, including construction, electrical and electronics, transportation, and consumer goods.

Production process

The production of copper-tin alloy strip classified under HS code 740931 typically involves a multi-step process. First, the copper and tin are melted and alloyed together to create the desired bronze composition. The molten alloy is then cast into ingots or billets, which are subsequently hot-rolled to the desired thickness. The rolled strip is then coiled and may undergo further processing, such as annealing or surface finishing, depending on the specific requirements of the end-use application.

Production inputs

The main inputs required for the production of copper-tin alloy strip under HS code 740931 include high-purity copper and tin as the primary raw materials. Additionally, the industry relies on specialized rolling and coiling equipment, as well as various consumables and utilities, such as energy, water, and lubricants, to facilitate the manufacturing process.

Production outputs

The copper-tin alloy strip produced under HS code 740931 is a versatile material that finds applications in a wide range of industries. It is commonly used in the manufacture of electrical components, plumbing fittings, decorative hardware, and various other products that require the unique properties of bronze, such as corrosion resistance, malleability, and aesthetic appeal. The output from this industry may be further processed or consumed by industries classified under other HS codes, such as 741510 Copper; articles for table, kitchen or other household articles and parts thereof, 853620 Electrical; automatic circuit breakers, for a voltage not exceeding 1,000 volts, and 870840 Motor vehicles; parts and accessories of bodies, bumpers, among others.
