9902.17.58 - Golf club driver heads, each stamped or otherwise permanently marked to indicate a loft under 9.5 degrees (provided for in subheading 9506.39.00)

This HTS category, 9902.17.58, specifically classifies golf club driver heads that are permanently marked to indicate a loft angle of less than 9.5 degrees. These are specialized components intended for use in the assembly or repair of golf equipment, and their classification is contingent upon this precise physical characteristic – the loft angle. The provision for this item within Chapter 99 signifies a temporary legislative or trade agreement-related modification to the standard tariff treatment, indicating a specific import regime or restriction applies.

While the broader HTS system encompasses a vast array of goods, this particular classification is distinct from general categories of sporting goods (Chapter 95) by focusing on a very specific component with defined technical parameters. It differs from sibling categories within Chapter 99, which would likely relate to other temporary modifications or restrictions on different types of goods, by its exclusive focus on golf equipment meeting a particular loft specification.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 9902.17.58 is definitive once the goods are identified as golf club driver heads with a permanently marked loft under 9.5 degrees. The parenthetical reference to subheading 9506.39.00 indicates that absent this specific Chapter 99 provision, these heads would typically fall under the broader heading for golf club parts and accessories.
