The HSN code 8457 identifies machining centres, unit construction machines (single station), and multi-station transfer machines for working metal. This code falls under Chapter 84 of the Harmonized System, which covers nuclear reactors, boilers, machinery, and mechanical appliances, and parts thereof.
Understanding HSN Code 8457
The Harmonized System of Nomenclature (HSN) is an internationally recognized product classification system used by customs authorities worldwide to classify goods for customs purposes. HSN code 8457 specifically categorizes sophisticated industrial machinery designed for precise metalworking operations.
Here's a breakdown of what the code covers:
- Machining Centres: These are highly advanced, computer-controlled (CNC) machine tools capable of performing multiple machining operations (like milling, drilling, boring, and tapping) on a workpiece in a single setup. They often have automatic tool changers and can rotate the workpiece, enabling complex geometries to be produced efficiently.
- Unit Construction Machines (Single Station): These machines are built from standardized, interchangeable units (like drilling heads, milling heads, and feeding units) and are typically designed for a specific operation or a sequence of operations on a single workpiece at one station. They are often used for high-volume production of specific components.
- Multi-Station Transfer Machines: These are complex, automated production lines where workpieces are transferred from one station to another, with different machining operations performed at each station. They are engineered for mass production of parts requiring a series of operations, significantly reducing cycle times and labor.
These machines are essential in various manufacturing sectors, including automotive, aerospace, and general engineering, due to their ability to produce parts with high precision and efficiency.

Applications and Importance
Machines classified under HSN 8457 are critical for modern industrial production. They enable:
- High Precision and Accuracy: CNC controls ensure tight tolerances and consistent quality.
- Increased Productivity: Automation and multi-tasking capabilities significantly reduce manufacturing time.
- Reduced Labor Costs: Less human intervention is required once the machines are set up and programmed.
- Versatility: Machining centres, in particular, can handle a wide range of tasks and materials, depending on their configuration.
