2908.99.20.00 - p-Nitrophenol

This classification covers p-Nitrophenol, a specific nitrated derivative of phenol. It is characterized by a nitro group (-NO2) attached to the para position of the phenol ring. This compound finds various applications, including as an intermediate in the synthesis of other chemicals, dyes, and pharmaceuticals. Its identity is confirmed by its chemical structure and properties, distinct from other nitrated phenol derivatives.

Within the broader category of "Halogenated, sulfonated, nitrated or nitrosated derivatives of phenols or phenol-alcohols," this subheading distinguishes p-Nitrophenol from other similarly derived compounds. While siblings such as "Other nitrophenols" (2908.99.25.00) or specific dinitro compounds like Dinitro-o-cresols (2908.99.33.00) and Dinitrobutylphenol (2908.99.40.00) are also nitrated derivatives, they represent different positional isomers or multiple nitro group substitutions. The key differentiator for 2908.99.20.00 is the singular nitro group at the para position of the phenol molecule.

As this subheading represents a leaf node, there are no further subdivisions. Therefore, the classification of p-Nitrophenol under this HTS code is specific and direct. When classifying, customs professionals should ensure the chemical in question is indeed p-Nitrophenol, identified by its unique chemical structure and CAS number, to differentiate it from other nitrophenol isomers or more complex nitrated phenol derivatives that would fall under sibling or parent categories.
