2927.00.40.00 - Products described in additional U.S. note 3 to section VI

This HTS classification covers diazo-, azo-, or azoxy-compounds that are specifically identified by additional U.S. note 3 to Section VI. These compounds are organic chemicals that contain one or more azo (-N=N-) or azoxy (-N=N(O)=) groups. The inclusion of "additional U.S. note 3" indicates that the scope of this category is further defined by specific U.S. legal text, likely outlining particular chemical structures, purity levels, or intended uses that distinguish them from other diazo-, azo-, or azoxy-compounds. Importers should consult this note for definitive inclusion criteria.

As a leaf node, this category does not have further subdivisions. Its distinctiveness lies in its reliance on the specific provisions outlined in additional U.S. note 3 to Section VI, rather than broader descriptive criteria found in sibling or higher-level categories. While other classifications within 2927.00.40.00 may exist, this particular code is reserved for products explicitly called out in that note. Therefore, classification here necessitates a direct match with the stipulations within the referenced U.S. note.

Examples of products that might fall under this classification, depending on the precise wording of additional U.S. note 3, could include specific dyestuffs, pigments, or chemical intermediates where the diazo, azo, or azoxy functionality is central to their chemical identity and is subject to particular regulatory or commercial considerations outlined in the note. Due diligence requires careful examination of the chemical properties and the official additional U.S. note to ensure accurate classification.
