9902.14.15 - Footwear for women, with outer soles and uppers of rubber or plastics (except vulcanized footwear and footwear with waterproof molded bottoms or vulcanized bottoms, including bottoms comprising an outer sole and all or part of the upper, and except footwear designed to be protective that is incomplete in its condition as imported), not covering the ankle or having a protective metal-toe cap, valued over $27/pair, designed to be worn in lieu of, but not over, other footwear as a protection against water, oil, grease or chemicals or cold or inclement weather where such protection is imparted by the use of a laminated textile and has openings in the bottom and/or side of the sole, or covered openings in the upper above the sole unit, or a combination thereof, designed to permit moisture vapor transport from under the foot (provided for in subheading 6402.99.33)

This HTS category, 9902.14.15, pertains to a specific type of women's footwear. The core requirements for classification here include outer soles and uppers constructed from rubber or plastics. Crucially, it excludes vulcanized footwear and footwear with waterproof molded or vulcanized bottoms, as well as those designed for protection with incomplete imported components. The footwear must not cover the ankle and lack a protective metal-toe cap. Furthermore, it must be valued over $27 per pair and be designed as a substitute for other footwear to provide protection against water, oil, grease, chemicals, or adverse weather conditions. This protection is achieved through a laminated textile and specific moisture vapor transport mechanisms, such as openings in the sole or upper.

Given that this is a leaf node within Chapter 99, which deals with temporary legislation and modifications, this specific classification likely represents a temporary duty or quota provision applied to footwear meeting these precise criteria. It is distinct from the broader categories within Section XII (Footwear, Headgear, Umbrellas...) by its inclusion under temporary import restrictions. While general footwear classifications (e.g., within Chapter 64) might cover similar items by material and construction, this 9902 code signifies a special import regime rather than a permanent tariff classification based solely on product characteristics. The detailed description emphasizes specialized protective features and a specific construction method designed for breathability, differentiating it from standard rubber or plastic footwear.
