8505 - Electromagnets; permanent magnets and articles intended to become permanent magnets after magnetization; electromagnetic or permanent magnet chucks, clamps and similar holding devices; electromagnetic couplings, clutches and brakes; electromagnetic lifting heads; parts thereof:

This HTS category, 8505, encompasses a range of electromagnetic and magnetic devices, along with their components. It specifically covers electromagnets used for generating magnetic fields when an electric current is applied, and permanent magnets designed to retain their magnetic properties. The scope also extends to holding devices such as magnetic chucks and clamps, which utilize magnetic force for securing workpieces, as well as electromagnetic couplings, clutches, and brakes used for power transmission and control. Finally, it includes electromagnetic lifting heads and all parts thereof.

When classifying within this chapter, it's crucial to distinguish these magnetic and electromagnetic apparatus from general electrical machinery and equipment covered in other headings of Chapter 85. For instance, simple magnets not intended for use in the specific applications listed (electromagnets, holding devices, power transmission) would fall elsewhere. Similarly, electrical motors or generators, while utilizing electromagnetic principles, are classified under separate headings based on their primary function.

The subcategories within 8505 provide further specificity for classification. For permanent magnets and articles intended to become permanent magnets after magnetization, the focus is on their inherent magnetic properties and potential. Electromagnetic couplings, clutches, and brakes are distinct by their function in controlling power transmission. The "Other, including parts" subheading serves as a residual category for items that fit the general description of electromagnets and permanent magnets but do not fall into the more specific subheadings, as well as components for all devices covered in this heading.
