Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing impurities rendering it a derivative
Slightly modified forms (e.g., nitrated) fall under later numerical headings per Chapter note on classification order.
If packaged with anticaking stabilizer for transport
Chapter note (f) keeps it under propionic acid if stabilizer is necessary for preservation and not for specific end-use.
If ethyl alcohol esters dominate in mixture
Esters of propionic acid with ethanol classified with acid per note 5(A)(B), but alcohol exclusions may apply if primary.
