2904.20.10.00 - p-Nitrotoluene

This classification covers p-Nitrotoluene, a specific organic chemical compound derived from toluene. It is characterized by the presence of a nitro group (-NO2) attached to the para position of the toluene molecule. p-Nitrotoluene is primarily used as an intermediate in the synthesis of dyes, pigments, pharmaceuticals, and other organic chemicals. Its precise chemical structure and reactivity are key to its distinct classification.

Within the broader category of sulfonated, nitrated, or nitrosated hydrocarbon derivatives, this subheading specifically isolates p-Nitrotoluene. It is distinguished from sibling categories such as p-Nitro-o-xylene and Trinitrotoluene (TNT) by the singular nitro group at the para position of a single benzene ring derived from toluene. Unlike the broader "Nitrated benzene, nitrated toluene (except p-nitrotoluene), or nitrated naphthalene" subheading, this code is for the specific para isomer, excluding other nitrated toluenes.

As this is a leaf node, there are no further subcategories. The classification of p-Nitrotoluene under 2904.20.10.00 is definitive for this specific chemical compound, ensuring its accurate treatment within international trade and customs procedures. Classification hinges on the exact isomer and the presence of only one nitro group in the specified position.
