Overview
This HTS classification, 9902.09.12, covers specific mixtures of chemical substances primarily used as industrial surfactants or emulsifiers. The designated mixtures include poly(oxy-1,2-ethanediyl), α-(2,4,6-tris(1-phenylethyl)phenyl)-ω-hydroxy-, phosphate, potassium salt (CAS No. 163436-84-8); poly(oxy-1,2-ethanediyl), α-(tris(1-phenylethyl)phenyl)-ω-hydroxy- (CAS No. 99734-09-5); and propane-1,2-diol (CAS No. 57-55-6). These components are known for their ability to reduce surface tension and facilitate the mixing of otherwise immiscible substances, making them valuable in various industrial applications.
As a classification within Chapter 99, this specific subheading pertains to temporary legislation and special provisions. Its purpose is to address specific importations that may be subject to particular trade agreement proclamations or temporary modifications, as outlined in the broader context of Section XXII. Unlike the primary commodity chapters (e.g., Chapter 01 for live animals), which classify goods based on their inherent nature and intended use in trade, this subheading focuses on regulatory and temporary import status rather than the fundamental categorization of goods.
Since 9902.09.12 is a leaf node, it does not have further subcategories. This indicates that any goods meeting the precise description of this mixture, as identified by its chemical names and CAS numbers, are directly classified under this specific provision without further subdivision. The classification relies entirely on the presence and identity of the enumerated chemical components and their inclusion within the defined mixture. The reference to subheading 3402.90.30 in the description highlights a potential underlying classification of these substances before applying this temporary provision.
