9902.03.90 - 4-Methyl-N,N-dipropoxyaniline (CAS No. 38668-48-3) (provided for in subheading 2922.19.70)

This HTS category, 9902.03.90, specifically covers the chemical compound 4-Methyl-N,N-dipropoxyaniline, identified by CAS No. 38668-48-3. Its inclusion within Chapter 99 signifies that this substance is subject to temporary legislation or modifications related to trade agreements or agricultural adjustment provisions. The "provided for in subheading 2922.19.70" notation indicates that while this specific temporary classification applies, the base classification for this substance would typically fall under the heading for other acyclic amino-alcohols and their derivatives.

As a leaf node within the HTS database, this category has no further subdivisions. Its existence as a distinct HTS code within Section XXII highlights a specific, likely temporary, regulatory or tariff treatment imposed on this particular chemical. The context of Section XXII and Chapter 99 suggests this classification is not based on the intrinsic physical or material properties of the compound itself, but rather on external factors such as trade policy, import restrictions, or specific agreements, differing from the permanent chemical classifications found in earlier chapters.
