2909.50.45.00 - Products described in additional U.S. note 3 to section VI

This HTS code, 2909.50.45.00, encompasses products classified under Additional U.S. Note 3 to Section VI, pertaining to specific ethers, ether-alcohols, ether-phenols, and their derivatives. These substances are characterized by the presence of both ether and phenolic functional groups, or ether and alcohol functional groups in conjunction with a phenol. The scope is further narrowed by the additional U.S. note, which provides specific criteria for inclusion beyond the general chemical structure.

This specific classification distinguishes itself from its sibling category, 2909.50.50.00, which is also designated as "Other." The distinction lies in the explicit reference to Additional U.S. Note 3. While both codes represent a residual category within the broader classification of ether-phenols and their derivatives, 2909.50.45.00 is reserved for those items that meet the specific stipulations of that particular note, implying a more precise definition or application intended by U.S. Customs and Border Protection.

As this is a leaf node within the HTS, there are no further subcategories. Classification under 2909.50.45.00 is final for products meeting the defined chemical structure and the specific requirements outlined in Additional U.S. Note 3. Importers should carefully review the text of Additional U.S. Note 3 to Section VI to ensure accurate classification, as it provides the definitive criteria for goods falling under this code.
