2918.29.65.00 - Products described in additional U.S. note 3 to section VI

This HTS classification, 2918.29.65.00, encompasses a specific subset of organic chemicals: carboxylic acids featuring a phenol function but lacking any other oxygen-containing functional groups, along with their related derivatives such as anhydrides, halides, peroxides, and peroxyacids. Crucially, the products classified here are further defined by Additional U.S. Note 3 to Section VI, which provides specific criteria for their inclusion. This means that beyond the basic chemical structure, specific regulatory or compositional requirements outlined in that note are determinative for classification under this code.

At this level of detail within Chapter 29, the "Other" subheadings indicate classifications that do not fit into more specifically defined categories. The distinction between 2918.29.65.00 and its sibling, 2918.29.75.00 (also described as "Other"), relies entirely on the stipulations of Additional U.S. Note 3 to Section VI. Importers and exporters must carefully consult this note to determine which of the "Other" categories applies, as the deciding factor is not a difference in basic chemical structure but rather adherence to the specific conditions set forth in the note.

As this is a leaf node, there are no further subcategories. Therefore, the classification hinges directly on meeting the requirements of Additional U.S. Note 3 to Section VI for products fitting the general description of phenolic carboxylic acids and their immediate derivatives. Examples might include certain specialty chemicals used in specific industrial processes where adherence to particular purity standards, manufacturing methods, or end-use declarations is mandated by the Additional U.S. Note.
