8505.20.00.00 - Electromagnetic couplings, clutches and brakes 🖩

This HTS category, 8505.20.00.00, specifically covers electromagnetic couplings, clutches, and brakes. These devices utilize electromagnetic principles to transmit or control mechanical power. Electromagnetic couplings are designed to connect and disconnect shafts, allowing for the engagement and disengagement of power transmission. Electromagnetic clutches operate similarly, enabling or preventing the rotation of one shaft relative to another through magnetic force. Electromagnetic brakes, on the other hand, use magnetic fields to arrest or slow down the motion of rotating machinery.

Distinguishing this category from its siblings, it's important to note that while all fall under the broader scope of electromagnets and related articles, 8505.20.00.00 is dedicated solely to the functional components that manage power transmission and motion control through electromagnetic action. Sibling categories may cover permanent magnets themselves or other miscellaneous electromagnetic devices and their parts. Therefore, classification under 8505.20.00.00 hinges on the primary function of the article being a system for coupling, clutching, or braking activated by electromagnetic force, rather than being a standalone magnet or a different type of electromagnetic apparatus.

As a leaf node, this category does not have further subcategories. Classification at this level is determined by the definitive nature of the article as an electromagnetic coupling, clutch, or brake. When classifying, consider the essential characteristics and intended use of the product. For instance, an article designed to engage or disengage mechanical power through the application of an electric current to generate a magnetic field would typically fall here, provided it is not primarily a permanent magnet or part of another article.
