This HTS category, 9902.02.59, specifically addresses Cyclopentanone (CAS No. 120-92-3). Its primary function is to provide a temporary or modified classification for this chemical compound, as indicated by its placement within Chapter 99, which deals with temporary legislation and trade agreement modifications. While the primary chemical classification for cyclopentanone typically falls under subheading 2914.29.50 of the Harmonized Tariff Schedule, this specific entry signifies a distinct tariff treatment for the imported substance under specific, likely time-limited, regulations.

It is crucial to understand that this category does not represent a broad class of goods like the sibling categories which cover live animals. Instead, it is a highly specific provision for a single chemical compound. The inclusion in Chapter 99 signifies that this classification is subject to special rules, potentially for reasons related to agricultural adjustments, trade policy, or other temporary legislative measures, distinguishing it from standard chemical classifications that lack such special provisions.

As this is a leaf node, there are no further subcategories under 9902.02.59. The classification is definitive for cyclopentanone when imported under the specific conditions necessitating its presence in Chapter 99. Importers must refer to the underlying legislative or proclamational text associated with this HTS code to fully understand the applicable duties, restrictions, or reporting requirements.
