Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If significant impurities alter chemical identity
Other acyclic polyamine derivatives with undefined composition fall under the residual 2921.59 provision.
If containing heterocyclic impurities
Presence of ring structures would shift classification to heterocyclic compounds in heading 2933.
If sold as formulated organic composite solvent
TEPA in organic solvent blends for specific industrial applications classifies as composites in 3814.
