Import Tips
• Provide detailed chemical analysis (NMR, MS) confirming aromatic structure and sulfur directly linked to carbon to avoid misclassification
• Include Safety Data Sheet (SDS) and purity certificate; thiophenol is hazardous and requires proper hazmat documentation
• Verify not sulfonated/halogenated derivatives, as those shift to earlier 2930 subheadings per chapter notes
