2922.29.61.00 - Products described in additional U.S. note 3 to section VI

This HTS classification covers specific amino-naphthols and amino-phenols, their ethers and esters, and their salts, which do not contain more than one type of oxygen function. The designation "other" at this level signifies that the products do not fall under more specific subheadings within the broader category of amino-alcohols and their derivatives, and are not otherwise specifically enumerated. Therefore, it acts as a residual category for such compounds when they do not meet the criteria for more precise classification.

The distinction from sibling categories, such as 2922.29.81 ("Other" under a different sub-classification), lies in the precise nomenclature and structural characteristics defined in the preceding HTS headings and subheadings. This specific node is reached after excluding more defined subcategories of amino-naphthols and amino-phenols, emphasizing the "other" aspect to capture compounds that fit the general definition but lack more specific defining features for narrower groupings.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Consequently, the practical classification for goods falling under 2922.29.61.00 relies on a thorough examination of the product's chemical composition, ensuring it aligns with the defined scope of amino-naphthols and amino-phenols, their ethers, esters, and salts, while also confirming it is not covered by any more specific preceding HTS designations that would take precedence.
