Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered primarily amino acid derivative
Certain amino-hydroxy acids classified earlier in 2922.19; however, true amino alcohols remain in 2922.50 per oxygen function specificity.
If when imported as fuel additive mixture
Antiknock preparations containing these compounds classified in Chapter 38, not pure organic chemicals.
If pre-formulated into surface-active preparations
Anionic organic surface-active agents fall under Chapter 34, not bulk chemicals of Chapter 29.

Import Tips & Compliance
• 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
