9902.16.15 - AC electric generators, each with a flywheel and an eddy-current loading device, the load being controlled magnetically (provided for in subheading 8501.61.00), designed for use in exercise equipment of subheading 9506.91

This HTS classification, 9902.16.15, covers specialized AC electric generators designed specifically for integration into exercise equipment falling under subheading 9506.91. These generators are distinguished by their inclusion of a flywheel and an eddy-current loading device, with the load controlled magnetically. The primary function of these generators is to provide a controlled resistance for exercise machines, such as stationary bicycles or elliptical trainers.

As a classification within Chapter 99, this entry represents a temporary or specialized tariff provision, distinct from the primary goods chapters like Chapter 85 (Electrical Machinery and Equipment) where the underlying AC electric generators (subheading 8501.61.00) are typically classified. While sibling categories within Chapter 99 would represent other temporary or restricted import items, this specific code targets a niche application of generators within the exercise equipment sector. Its precise coverage is limited to generators meeting all stipulated design and functional criteria for use in the specified exercise equipment category.

Since this HTS code is a leaf node, there are no further subcategories. Classification under 9902.16.15 is final and depends on the generator meeting the precise description, including its magnetic eddy-current loading mechanism and intended application in exercise equipment classified under 9506.91. Any deviation in the generator's design or intended use would necessitate classification under a different HTS code.
