9902.05.23 - 3-{[3-(Dodecylsulfanyl)propanoyl]oxy}-2,2-bis({[3-(dodecylsulfanyl)pro- panoyl]oxy}methyl)propyl 3-(dodecylsulfanyl)propanoate) (CAS No. 29598-76-3) (provided for in subheading 2930.90.91)

This HTS code, 9902.05.23, specifically designates a complex organic compound identified by CAS No. 29598-76-3. The chemical name, 3-{[3-(dodecylsulfanyl)propanoyl]oxy}-2,2-bis({[3-(dodecylsulfanyl)propanoyl]oxy}methyl)propyl 3-(dodecylsulfanyl)propanoate, indicates a molecule characterized by multiple dodecylsulfanyl propanoyl ester groups attached to a glycerol backbone. This compound is provided for under subheading 2930.90.91, highlighting its inclusion within the broader category of organosulfur compounds.

This temporary tariff provision distinguishes itself from the numerous other sibling categories within Chapter 99, which generally cover temporary legislation, trade agreement modifications, and agricultural import restrictions. Unlike those broader provisions, 9902.05.23 is highly specific, applying solely to this particular chemical substance. Furthermore, it is distinct from the primary chemical classifications found in Chapters 28 and 29, which detail more general organic and inorganic compounds. The nature of the goods under this code suggests they are likely specialized chemicals with specific industrial or commercial applications, often subject to temporary duty rates or restrictions.

As this is a leaf node, there are no further subcategories for this specific HTS code. Classification at this level is precise, focusing on the exact chemical identity and structure of the substance. The presence of this code under Chapter 99 signifies that its tariff treatment is temporary and subject to change based on specific trade policies or legislative actions, rather than being a permanent classification within the core HTS structure.
