2922.29.13.00 - o-Aminophenol; and 2,2-Bis[4-(4-aminophenoxy)phenyl]propane 🖩

This HTS category, 2922.29.13.00, specifically covers two distinct chemical compounds: o-Aminophenol and 2,2-Bis[4-(4-aminophenoxy)phenyl]propane. Both are classified under amino-phenols, excluding those with multiple oxygen functions and their derivatives. o-Aminophenol is a basic organic compound with both an amine and a hydroxyl group attached to a benzene ring, positioning it as a fundamental building block in various chemical syntheses. The second compound, 2,2-Bis[4-(4-aminophenoxy)phenyl]propane, is a more complex molecule featuring multiple amine and ether linkages, indicating its potential use in specialized applications such as polymer production.

The distinction from sibling categories lies in the specific chemical structures and functionalities of the listed compounds. For instance, while other siblings in this group might include various substituted aminophenols, anisidines, or phenetidines, this particular code isolates the unadulterated o-Aminophenol and the specific bis-phenoxypropane derivative. This precision is crucial for accurate tariff application, ensuring that only these exact compounds are classified here, and not other related or similarly functionalized chemicals that fall under different subheadings.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, the classification terminates with the explicit identification of o-Aminophenol and 2,2-Bis[4-(4-aminophenoxy)phenyl]propane. Importers and exporters should meticulously verify that the imported or exported substances precisely match these descriptions to ensure correct duty assessment and compliance with trade regulations. Any deviations in chemical structure or the presence of other functional groups would necessitate classification under a different HTS code.
