9902.11.35 - Poly(phenol-co-formaldehyde-co-4-(1,1-dimethylethyl)phenol) (CAS No. 28453-20-5) (provided for in subheading 3909.40.00)

This HTS classification, 9902.11.35, specifically covers Poly(phenol-co-formaldehyde-co-4-(1,1-dimethylethyl)phenol), identified by CAS No. 28453-20-5. This product falls under a temporary legislation chapter, indicating its classification is driven by specific trade agreements or statutory provisions rather than its inherent material composition alone. It is important to note that this classification is provided for in subheading 3909.40.00, suggesting that its underlying chemical nature aligns with phenolic resins for molding or manufacture.

As this node is a leaf node within Chapter 99, it does not have further subcategories. Therefore, distinguishing it from siblings involves understanding that Chapter 99 itself is dedicated to temporary legislation and special provisions. Unlike the primary chapters of the HTS which classify goods based on inherent characteristics (e.g., live animals, textiles, machinery), Chapter 99 nodes are contingent on external proclamations and legislative actions. The specific identifier 9902.11.35 signifies a unique modification or provision applied to the commodity otherwise potentially classifiable under Chapter 39, and its application is strictly dictated by the terms of the legislation it references.
