9902.05.12 - 1-(Octadecyldisulfanyl)octadecane (CAS No. 2500-88-1) (provided for in subheading 2930.90.29).

This HTS category, specifically 9902.05.12, covers the chemical compound 1-(Octadecyldisulfanyl)octadecane, identified by CAS No. 2500-88-1. While its base classification is found under subheading 2930.90.29, this specific entry in Chapter 99 signifies a temporary legislative provision or modification. These provisions often relate to temporary trade agreements or special import restrictions, meaning the classification here is tied to a specific time-limited policy rather than the inherent nature of the chemical itself, which would be a sulfur compound.

As this is a leaf node within Chapter 99, there are no further subcategories to explore. Its uniqueness lies not in its physical or chemical properties relative to other Chapter 99 entries (which all deal with temporary measures), but rather in the specific chemical compound it pertains to and the underlying temporary legislation it is subject to. Therefore, classification under this code necessitates understanding both the chemical identity of 1-(Octadecyldisulfanyl)octadecane and the specific trade or legislative context under which this 9902.05.12 code is active.
