Which factors influence the price of this Nardostachys spikenard oil?

Key price drivers: (1) marker content — valeranone and spathulenol levels directly determine grade (Ph.Eur.-grade commands a premium); (2) CITES scarcity — spikenard is CITES Appendix II with a national quota (2025: 3.8 t), so legal, traceable lots are structurally tight; (3) origin and harvest — Dao-di highland batches (Aba/Gannan/Guoluo/Qamdo) cost more; (4) extraction process — supercritical CO2 and molecular distillation cost more than steam distillation; (5) certifications (FairWild, Halal, Kosher) and (6) order volume.
