Import Tips
• Provide infrared spectroscopy (IR) or NMR data to distinguish from triethanolamine and confirm molecular structure
• Comply with TSCA pre-manufacture notification if new chemical use; check REACH equivalents for EU transshipments
• Label with GHS hazard pictograms for corrosivity; improper packaging leads to common CBP holds
