Mexican Yam Diosgenin Powder from Japan
Diosgenin is a steroidal sapogenin extracted from Mexican wild yam, used as a precursor to progesterone. Although it has a steroid structure, it is not itself an oestrogen or progestogen, nor a derivative or structural analogue used primarily as a hormone. Therefore, it does not meet the terms of heading 29.37 and is excluded from this tariff item.

Import Tips
• Clarify with the CBSA that diosgenin is a precursor, not a hormone itself
• Provide evidence of its use as an intermediate, not as a hormone
• Consider classification under other steroid headings
