2922.39.25.00 - Products described in additional U.S. note 3 to section VI

This HTS category, 2922.39.25.00, encompasses amino-aldehydes, amino-ketones, and amino-quinones, excluding those with multiple oxygen functions, and their salts. These compounds are characterized by the presence of both an amino group (-NH2, -NHR, or -NR2) and an aldehyde (-CHO), ketone (RCOR'), or quinone functional group within the same molecule. The classification here specifically applies to products falling under additional U.S. note 3 to section VI, indicating a particular set of criteria or substances that are defined within that note for specialized classification purposes.

Distinguishing this category from its sibling, 2922.39.45.00 ("Other"), is crucial. While both fall under the broader "Other" aromatic amino-aldehydes, ketones, and quinones, the .25.00 subheading is reserved for those explicitly identified by the aforementioned additional U.S. note 3. This note provides a specific list or set of characteristics that govern the classification of particular compounds, effectively carving out a distinct group from the more general "Other" category at this level. Therefore, classification into 2922.39.25.00 relies on meeting the defined requirements of U.S. note 3, rather than simply being an aromatic amino-aldehyde, ketone, or quinone not specified elsewhere.

As a leaf node, this category does not have further subcategories. Classification decisions within this subheading will therefore depend directly on whether the imported merchandise meets the specific criteria outlined in additional U.S. note 3 to section VI. Importers and customs brokers must carefully consult this note to accurately determine if their aromatic amino-aldehydes, amino-ketones, or amino-quinones qualify for classification under 2922.39.25.00.
