FAQ for OEM buyers
Q. Is sudachi a Tokushima regional product (chiriki-hin) and does that affect labeling?
Yes — sudachi is a Tokushima Prefecture flagship agricultural product, with the prefecture supplying over 95% of Japan's commercial sudachi. While 'sudachi' itself is not GI-registered with 農林水産省 (Ministry of Agriculture, Forestry and Fisheries), Tokushima provenance is a key authenticity marker; suppliers can typically provide origin documentation on request.

Q. Is Citrus Sudachi Peel Extract listed in INCI/CosIng?
Yes, Citrus Sudachi Peel Extract is listed in CosIng/INCI dictionaries with skin-conditioning function, and is acceptable for cosmetic use in Japan, EU, US, and most major markets. Botanically, sudachi (Citrus sudachi) is a separate species from yuzu (Citrus junos) and kabosu (Citrus sphaerocarpa).

Q. Are there phototoxicity concerns with sudachi peel extract or oil?
Cold-pressed sudachi peel oil, like other citrus peel oils, may contain furocoumarins and should be evaluated against IFRA standards for leave-on use. Water/BG/glycerin sudachi peel extracts typically have low furocoumarin content; request a furocoumarin profile from the supplier for leave-on applications.

Q. What is the typical MOQ and seasonality for sudachi extract supply?
Sudachi peel extract MOQ is typically 5-20 kg from Japanese suppliers; the harvest season runs August-October so freshly-pressed material is most available in autumn. Frozen and lyophilized peel forms are available off-season.
