Overview
This HTS category, 9902.10.48, specifically covers certain specialized mixtures. These mixtures are defined by their precise composition, requiring a minimum of 88% by weight of poly[oxy(dimethylsilanediyl)] bis[omega-butoxypoly(oxypropylene)] ether (CAS No. 67762-96-3). They also contain up to 8% by weight of α-butyl-ω-hydroxylpoly(oxypropylene) (CAS No. 9003-13-8) and a minor amount, less than 4% by weight, of silica dimethylsilylate (CAS No. 68611-44-9). These specific formulations are typically used in industrial applications, often as sealants, adhesives, or as components in more complex products.
As a temporary provision within Chapter 99, this code is distinct from the standard HTS classifications found in earlier chapters which categorize goods based on their inherent nature and primary use (e.g., chemicals, machinery, textiles). Unlike sibling categories in Chapter 99 which might cover other temporary trade measures or specific import restrictions under Section 22, 9902.10.48 is narrowly focused on this particular chemical mixture, often to implement specific trade agreement provisions or temporary import duties.
Since this is a leaf node within the HTS database, it does not have further subdivisions. The classification is definitive for mixtures meeting the exact compositional criteria. For classification purposes, importers must verify that the goods precisely match the described percentages of each chemical component to ensure correct duty assessment and compliance with the temporary legislation under which this code falls. The reference to subheading 3824.90.92 indicates the underlying classification of these types of mixtures in the absence of this temporary provision.
