Magnets; permanent magnets and articles intended to become permanent magnets after magnetisation, other than of metal

HS code 850519 covers a wide range of permanent magnets and magnetic articles, excluding those made of metal. These magnets play a crucial role in various industries, from electronics and automotive to medical equipment and renewable energy. Their unique properties, such as high magnetic strength and resistance to demagnetization, make them indispensable components in countless applications that drive economic growth and technological advancement.

The production of permanent magnets and magnetic articles under HS code 850519 typically involves a multi-step process. Key techniques include powder metallurgy, injection molding, and sintering. Manufacturers carefully select and blend raw materials, such as rare earth elements, ferrites, and polymers, to achieve the desired magnetic properties. The materials are then subjected to high-pressure compaction, followed by heat treatment to enhance their magnetic characteristics and durability.

The main inputs required for the production of permanent magnets and magnetic articles under HS code 850519 include rare earth elements (e.g., neodymium, samarium, and cobalt), ferrite materials, and various polymers or resins. Specialized machinery, such as powder compaction presses, sintering furnaces, and injection molding equipment, are also essential for the manufacturing process. Additionally, the industry relies on advanced research and development to continuously improve the performance and cost-effectiveness of these magnetic products.

Permanent magnets and magnetic articles produced under HS code 850519 find applications in a wide range of industries. They are commonly used in electric motors, generators, sensors, speakers, and various electronic devices. These magnets are also crucial components in 850511 (Generators; generating sets, electric, with compression-ignition internal combustion piston engines (diesel or semi-diesel engines)) and 850520 Generating sets; electric, with spark-ignition internal combustion piston engines, as well as in 902780 (Instruments and apparatus for physical or chemical analysis, e.g. polarimeters, refractometers, spectrometers, gas or smoke analysis apparatus; instruments and apparatus for measuring or checking viscosity, porosity, expansion, surface tension or the like; instruments and apparatus for measuring or checking quantities of heat, sound or light (including exposure meters); microtomes).
