9902.05.44 - Dimethyl, methyl (polyethylene oxide acetate-capped) siloxane (CAS No. 70914-12-4) (provided for in subheading 2931.90.90)

This HTS category, 9902.05.44, specifically covers Dimethyl, methyl (polyethylene oxide acetate-capped) siloxane, identified by CAS Number 70914-12-4. While its primary classification is found under subheading 2931.90.90, this entry within Chapter 99 signifies a temporary legislative or trade agreement modification. Therefore, goods falling under this code are subject to special provisions that temporarily alter their import status or requirements, often in response to specific trade policies or agricultural adjustments.

Distinguishing this category from its numerous siblings within the broader HTS database is crucial. Unlike the foundational chapters that classify live animals or common agricultural products, Chapter 99 operates as a distinct layer for temporary measures. This means that while the chemical substance itself has a permanent classification, its presence under 9902.05.44 indicates it is currently subject to specific, time-limited trade regulations rather than its inherent material composition.

As this is a leaf node, there are no further subcategories within 9902.05.44. The classification is definitive at this level, meaning any import or export of Dimethyl, methyl (polyethylene oxide acetate-capped) siloxane must adhere to the specific temporary provisions indicated by this HTS code, in addition to its permanent classification. Importers and exporters should consult the relevant trade agreements and proclamations associated with Chapter 99 to fully understand the current requirements for this product.
