Equine Pregnenolone Crystals
Pregnenolone derived from equine adrenal glands is a precursor to other steroid hormones, including progestins. 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.
