9902.15.58 - Pedestal column assemblies comprising parts for oscillating electric fans, presented in the assembled condition, each consisting of upper and lower tubes of steel, with thermoplastic collet (sleeve) covering the connection point of such tubes together with accompanying collet insert and allowing the two tubes to be locked at adjustable intervals (provided for in subheading 8414.90.10)

This HTS classification, 9902.15.58, specifically covers pedestal column assemblies designed as components for oscillating electric fans. These assemblies are presented in a pre-assembled state and are characterized by their construction from steel upper and lower tubes. A key distinguishing feature is the thermoplastic collet or sleeve that encases the connection point of these tubes, working in conjunction with an accompanying collet insert. This design allows for the secure locking of the two tubes at adjustable intervals, a critical function for the operation of fan pedestals.

Distinguishing this category from its siblings at the Chapter 99 level is its highly specific nature. Chapter 99 of the HTS is dedicated to temporary legislation, modifications, and restrictions. Unlike broader categories that might deal with general machinery parts or electrical components, 9902.15.58 targets a precise set of parts with a defined assembly and functional characteristic, tied to a specific end-use (oscillating electric fans). The "provided for in subheading 8414.90.10" note within its description indicates that while these are specific fan parts, their primary classification under the general tariff schedule would be as parts of air or gas pumps/ventilators.

As this classification (9902.15.58) represents a leaf node within the HTS database, there are no further subcategories to explore. The classification therefore stands as the most granular entry for these particular pedestal column assemblies. Its existence within Chapter 99 signifies a temporary measure or special provision that supersedes or modifies the general classification of these parts, likely for reasons of trade policy, import restrictions, or specific trade agreements. Therefore, import and export professionals must refer to the specific rulings or legislation associated with this code to understand its full implications beyond the physical description of the product.
