8302.41.30.00 - Door closers (except automatic door closers), and parts thereof

This category specifically covers mechanical door closers designed for installation on doors, excluding automatic door closers. It also encompasses any parts specifically manufactured for these types of door closers. The defining characteristic is their function in controlling the closing action of a door through mechanical means, typically involving springs, hydraulic, or pneumatic mechanisms. These are distinct from automatic door closers, which operate without manual intervention once a door is opened.

While other categories under "Other mountings, fittings and similar articles, and parts thereof: Suitable for buildings" might include general hardware for construction, this node is dedicated solely to the mechanism and components of non-automatic door closers. The emphasis is on the specific function of controlled door closure and not on broader architectural hardware like hinges, handles, or locks, unless they are integral parts of these particular door closing devices.

As this classification represents a leaf node, it does not have further subcategories. Therefore, the focus for classification purposes is on the precise identification of the item as a non-automatic door closer or a part thereof. Importers and exporters should verify that the product's design and intended use align with the mechanical operation and specific function of controlling a door's swing, differentiating it from electrical or sensor-activated automatic systems.
