Crude wool grease (1505001000) is the unrefined fat recovered directly from wool scouring liquor, while 1505009000 covers refined derivatives including lanolin (anhydrous or hydrous), lanolin alcohols, and lanolin acids.

Yes. Lanolin used as an ingredient in cosmetics is subject to FDA's cosmetic ingredient safety framework, and lanolin used in OTC drug products (such as skin protectants) must meet USP or NF monograph specifications. Importers of pharmaceutical-grade lanolin should ensure the foreign supplier holds appropriate GMP documentation and that the product meets purity standards required for the intended application.
