9902.03.86 - 2,2'-[[(1S,2S)-1,2-Diphenyl-1,2-ethanediyl]bis(im- inomethylene)]bis[6-(1,1-dimethylethylphenol] (CAS No. 481725-63-7) (provided for in subheading 2921.59.40)

This HTS category, 9902.03.86, specifically covers the chemical compound 2,2'-[[(1S,2S)-1,2-Diphenyl-1,2-ethanediyl]bis(im- inomethylene)]bis[6-(1,1-dimethylethylphenol], also identified by CAS Number 481725-63-7. This classification is found within Chapter 99, which pertains to temporary legislation, temporary modifications proclaimed pursuant to trade agreements, and additional import restrictions. The inclusion of this specific chemical under this chapter indicates it is subject to special import provisions or limitations beyond the standard tariff classifications.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its purpose is to denote a specific, temporarily regulated product. Unlike the broad categories of live animals found in the earlier chapters of the HTS (e.g., Chapters 01), which classify based on species and broad biological classifications, 9902.03.86 focuses on a particular chemical substance with precise structural and functional properties, subject to specific trade policy measures.

The fact that this entry is "provided for in subheading 2921.59.40" signifies that while the primary classification for the chemical itself might reside in Chapter 29 (Organic Chemicals), its importation under these specific circumstances is subject to the temporary or special provisions outlined in Chapter 99. This suggests that importers must consider both the chemical nature of the product and the prevailing trade regulations or restrictions associated with its import.
