Prednisone Micronized Powder
Micronized prednisone powder with particle size reduced for improved bioavailability in inhalation and topical formulations. Remains classified as pure prednisone under HTS 2937.21.00.30 since physical form modification doesn't change chemical identity as a steroidal hormone. Used primarily for hormone therapy in respiratory conditions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing heterocyclic ring structure prioritized
Chapter notes require classification in last occurring heading; some steroid derivatives might compete with oxygen heterocycles but prednisone specifically named.
If pre-mixed with pharmaceutical excipients
Bulk medicaments not in dosage form shift from pure chemicals to Chapter 30 preparations.
If precursor ketone classified separately
Synthetic intermediates before final prednisone structure complete would use earlier hydrocarbon derivative headings.
