Pseudocumene (1,2,4-Trimethylbenzene)
Pseudocumene is a colorless, flammable liquid cyclic hydrocarbon with the chemical formula C9H12, specifically 1,2,4-trimethylbenzene. It falls under HTS 2902.90.10.00 as a specified 'other' cyclic hydrocarbon distinct from benzene, toluene, and xylene. Primarily used as a solvent and chemical intermediate in industrial applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from coal tar or containing mixed C9 aromatics
Coal tar oils containing mixed alkylbenzenes like pseudocumene fall under Chapter 27 as mineral fuels, not pure Chapter 29 chemicals.
If imported as a chemical mixture or formulation with additives
Mixtures of chemicals not specifically provided for elsewhere are classified under heading 3824, excluding pure single compounds of Chapter 29.
If classified as other specified cyclic hydrocarbons
While 2902.90.10.00 specifically names pseudocumene, other trimethylbenzene isomers may fall under different 2902.90 subheadings.

Import Tips & Compliance
• Provide detailed chemical purity certificates and CAS number (95-63-6) documentation to confirm classification as pseudocumene
• Ensure proper hazardous material labeling (UN 2321, flammable liquid) and compliance with DOT/UN transport regulations
• Avoid misclassification as mixed alkylbenzenes; specify single-isomer content to prevent reclassification under 2707
