Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2921.19.11.00Higher: 137.5% vs 44%

If primary aromatic amine like aniline

Aromatic monoamines classified earlier in 2921.19.11; acyclic in .61

3824.99Lower: 17.5% vs 44%

If impure mixture >2% contaminants or with solvents

Chapter 29 excludes mixtures not meeting chemically defined criteria; becomes chemical preparation

2903.15.00.00Lower: 43% vs 44%

If classified as saturated acyclic alcohol amine

Some ethanolamines may fall under oxygen-function heading 2905 if oxygen group predominates

Import Tips & Compliance

• Provide Certificate of Analysis confirming purity >98% as chemically defined compound per Chapter 29 note (a)

• Declare exact CAS number (109-89-7) on entry; impurities must not exceed 2% to avoid reclassification

• Ensure UN 2685 hazmat labeling for corrosive liquid; common pitfall is missing SDS documentation
