Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cyclic polymer impurity predominates
Chapter notes exclude certain cyclic structures from 2932 but could affect purity classification.
If pre-mixed with ointment base
Any excipient addition creates Chapter 30 mixed medicaments.
If propionate ester emphasis over steroid base
Unsaturated acyclic carboxylic esters heading if functional group prioritized.

Import Tips & Compliance
• Specify 17-propionate, 21-chloride substitution pattern; impurities >0.5% risk reclassification
• Rx-only status requires prescription drug import license; verify ANDA status
• Potency limits (max 0.05% in formulations) affect bulk import quantities permitted
