8504.90.96.34 - Laminations for incorporation into stacked cores

This category encompasses laminations specifically designed for integration into stacked cores used in electrical transformers. These laminations are thin sheets of magnetic material, typically silicon steel, which are stacked and insulated to form the core of a transformer. The primary function of these laminations is to provide a low-reluctance path for magnetic flux, minimizing energy losses through hysteresis and eddy currents within the transformer. The "incorporation into stacked cores" aspect is crucial, indicating that these are components of a larger assembled core, not finished cores themselves.

Distinguishing this category from its siblings, 8504.90.96.38 covers the assembled stacked cores themselves, which are the product of assembling multiple laminations. Similarly, 8504.90.96.42 refers to wound cores, which are constructed differently. This category, 8504.90.96.34, is specifically for the individual laminated sheets before they are assembled into a complete stacked core. The distinction lies in the stage of manufacture and assembly.

As this is a leaf node within the HTS classification system, there are no further subcategories. Therefore, the focus remains on the precise definition of these laminations as components intended for stacked core construction. Classification under this heading relies on verifying that the goods are indeed laminations and are intended for this specific application within transformer manufacturing, as opposed to being general electrical sheet metal or parts for other types of cores.
