2907.19.61.00 - 2-tert-Butylethylphenol; 6-tert-Butyl-2,4-xylenol; and Xylenols and their salts

This HTS classification covers specific monophenolic compounds, including 2-tert-Butylethylphenol and 6-tert-Butyl-2,4-xylenol, as well as xylenols and their salts. These are organic chemical substances characterized by the presence of a hydroxyl group directly attached to an aromatic ring, with additional alkyl substituents and, in the case of xylenols, multiple methyl groups. This category is reserved for these particular phenol derivatives that do not fall under more specific subheadings within the broader phenol classifications.

It is important to distinguish this category from its sibling, 2907.19.80.00, which is also designated for "Other" monophenols. While both are residual categories, 2907.19.61.00 specifically enumerates the aforementioned tert-butylated phenols and xylenols, implying that other unlisted monophenols would typically be classified under 2907.19.80.00. The presence of the tert-butyl group and specific xylenol structures are key differentiators for classification under this heading.

As this is a leaf node within the HTS structure, there are no further subcategories to explore. Classification under 2907.19.61.00 is therefore final for the specified compounds and their salts, provided they meet the general criteria for monophenols and do not have a more precise classification elsewhere in Chapter 29. The purity, form, and intended use of these chemicals are critical factors to consider during the classification process.
