Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically modified structural analogue rather than pure progesterone
Modified steroid hormones not specifically enumerated as progesterone fall under the 'other' steroidal hormones subheading.
If pre-formulated as finished dosage form like capsules or injections
Medicaments containing progesterone as active ingredient are classified in Chapter 30 as pharmaceutical products rather than bulk hormones.
If imported as veterinary hormone product
Hormones used primarily in animal applications may fall under different hormonal subheadings based on end-use designation.

Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming USP purity ≥99% and identity by HPLC/GC to verify classification as pharmaceutical progesterone
• Include FDA Drug Master File (DMF) reference if applicable; ensure proper pharmaceutical import registration via FDA prior notice
• Avoid misclassification as veterinary hormones; specify human pharmaceutical end-use in import documentation to prevent duty reclassification
