Overview
This HTS classification, 9902.11.32, specifically covers a particular type of polymer: Poly{(azacyclotridecan-2-one)-co-(1,3-benzenedicarboxylic acid; 1,4-benzenedicarboxylic acid)-alt-(1,6-hexanediamine; 4,4'-methylenebis[cyclohexanamine]; 4,4'-methylenebis[2-methylcyclohexanamine])}, identified by CAS Number 1030611-14-3. While the broader scope of Section XXII and Chapter 99 deals with special classification provisions and temporary measures, this specific subheading is designated for this precisely defined chemical compound, which is also provided for under subheading 3908.90.70. The inclusion under Chapter 99 signifies its temporary or specific classification status, overriding or supplementing its usual placement within the Chapters 1-97.
Unlike the numerous sibling categories at the root of the HTS database, which cover a vast array of physical goods from live animals to manufactured products, this entry is highly specialized. It is not a general category for plastics or polymers but rather a very specific designation for a complex synthesized material. Its distinction lies in its precise chemical composition and its particular classification under temporary provisions, rather than its material type or general end-use, which would be the primary distinguishing factors for many other HTS categories.
As this is a leaf node, there are no subcategories to introduce. Classification within 9902.11.32 is final and determined by the exact chemical identity of the imported product. The primary classification criterion is the precise matching of the imported substance to the detailed chemical description and CAS number provided. Any deviation in chemical structure would necessitate re-evaluation and likely classification under a different HTS code, potentially the primary classification code indicated (3908.90.70) or another specialized provision if applicable.
