Propionic Acid 99% Technical Grade
Propionic acid (C2H5COOH) is a straight-chain saturated acyclic monocarboxylic acid used primarily as a preservative and intermediate in chemical synthesis. This technical grade product, with 99% purity, falls under HTS 2915.50.1000 as it matches the chemical definition of propionic acid without halogenation, sulfonation, or other modifications specified in the heading. It is commonly imported in bulk for industrial applications like feed preservation.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a stabilized solution for safety/transport
Chapter note (f) allows classification under propionic acid if stabilizer is added solely for preservation/transport, but solutions may shift if rendered suitable for specific use.
If mixed with other substances exceeding Chapter 29 mixture limits
Mixtures not purely propionic acid or its simple derivatives fall outside Chapter 29 per exclusion notes, moving to miscellaneous chemical preparations.
If diluted/formulated specifically for fertilizer use
End-use formulations like mineral/chemical fertilizers containing propionic acid derivatives are excluded from Chapter 29 and classified by function.
