9902.03.58 - 2-Ethyl-N-[(2S)-1-methoxypropan-2-yl]-6-methylaniline (CAS No. 118604-70-9) (provided for in subheading 2921.42.65)

This HTS category, 9902.03.58, specifically covers the chemical compound 2-Ethyl-N-[(2S)-1-methoxypropan-2-yl]-6-methylaniline, identified by CAS Number 118604-70-9. This particular substance is designated for temporary classification under this provision, while its standard tariff treatment is found in subheading 2921.42.65, which pertains to aniline and its derivatives. The inclusion in Chapter 99 signifies that this classification is subject to temporary legislation or modifications, potentially related to trade agreements or specific import restrictions under Section 22 of the Agricultural Adjustment Act.

Given its position within Chapter 99 of the Harmonized Tariff Schedule, this category stands apart from the primary commodity classifications found in Chapters 1 through 97. Siblings to this node would typically be other temporary or special provisions also found within Chapter 99, addressing unique import circumstances, temporary tariff suspensions, or specific quotas. It is important to distinguish this entry from the main chemical classifications in Chapter 29, as its presence here indicates a temporary, potentially duty-free or specially regulated import status, rather than a permanent classification.

As this node represents a "leaf node," it does not possess any subcategories. Classification is definitively established at this level for the specified chemical compound. Therefore, the focus for classification professionals is to confirm the identity of the imported merchandise against the precise description and CAS number provided, and to be aware of any associated temporary modifications or restrictions governing its importation.
