p-Xylene (Para-Xylene)
p-Xylene is a colorless, flammable liquid aromatic hydrocarbon with the chemical formula C6H4(CH3)2, classified under HTS 2902.43.00.00 as a specific xylene isomer within cyclic hydrocarbons. It is primarily used as a feedstock in the production of purified terephthalic acid (PTA) for polyester fibers and resins.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If crude or unrefined mixtures containing p-xylene from petroleum sources
Aromatic hydrocarbon mixtures from Chapter 27 take precedence over pure compounds if not separately defined.
If p-xylene dissolved in solvents for safety/transport exceeding chapter note (e) limits
Solutions beyond normal transport preparations fall into mixtures of Chapter 38 rather than pure Chapter 29 compounds.
If p-xylene with added stabilizers or anti-dusting agents rendering it suitable for specific non-general use
Chapter note (g) excludes additions that make products particularly suitable for specific uses from pure compound headings.

Import Tips & Compliance
• Verify purity levels via Certificate of Analysis (COA) as impurities may affect classification under chapter 29 notes
• Ensure proper UN 1307 hazardous material documentation and IMDG/49CFR compliance for flammable liquid transport
• Include end-use declaration to avoid misclassification into Chapter 27 if resembling crude petroleum mixtures
