Overview
This HTS category, 9902.03.31, specifically covers Ethyl (RS)-4-cyclopropyl(hydroxy)methylene-3,5-dioxocyclohexanecarboxylate, also known by its trade name Trinexapac-ethyl. This classification is provided for under subheading 2918.99.50, indicating its primary chemical nature as an organic carboxylic acid with other oxygen hetero-atom functional groups. The use of Chapter 99 codes signifies that this item is subject to special classification provisions, potentially due to temporary legislation, trade agreement modifications, or import restrictions enacted under Section 22 of the Agricultural Adjustment Act. Therefore, classification here is determined by its chemical identity and its status under these specific trade policies.
While sibling categories in Chapter 99 would cover other items under special classification provisions, 9902.03.31 is unique in its specific identification of Trinexapac-ethyl. The broader HTS structure begins with live animals in Chapter 01, progressing through various chapters detailing agricultural products, live animals, and processed goods. However, the "99" series chapters are distinct, addressing goods that, regardless of their primary commodity classification, are subject to additional regulatory or legislative controls. This particular entry serves as an example of how specific chemical compounds can be designated within these special provisions, highlighting the importance of consulting all applicable HTS chapters and notes for accurate classification.
As this is a leaf node, there are no further subcategories within 9902.03.31. Classification at this level is final, and importers must ensure that the goods precisely match the chemical description and CAS number provided. Any deviations in chemical composition or if the product is intended for a use not covered by the originating subheading (2918.99.50) would necessitate a re-evaluation of the HTS classification. The presence of this code within Chapter 99 underscores that beyond its inherent chemical properties, its import is governed by specific legal or trade policy requirements.
