FAQ for OEM buyers

Q. What MOQ and lead time should buyers expect for Wakayama or Tamba sansho?

Supplier-disclosed industry ranges are typically 1–10 kg for dried whole peppercorn lots and 100 g – 5 kg for milled powder, with 4–8 week lead times for Wakayama (Arida) or Tamba (Hyōgo) origin material. Smaller test lots may be available outside the harvest window from inventory; fresh-season material from May–June (young pods) and August–October (mature peppercorns) is allocated earliest to standing customers.

Q. Is English documentation (COA, allergen statement, origin certificate) typically available?

Mid- and large-scale Japanese spice processors generally issue English COA and origin documentation on request, with a reissue lead time of 1–2 weeks beyond the production lead time. Smaller regional cooperatives may only supply Japanese-language documentation; in those cases buyers usually engage a trading-house intermediary that can re-issue in English. Specify required test parameters (microbiology, heavy metals, residual pesticides) at the RFQ stage.

Q. Are organic or specialty-grade sansho options available?

Organic JAS-certified sansho is produced in limited volume in Wakayama and Hyōgo, primarily from established satoyama growers. Buyers should expect smaller MOQ ceilings (often capped per harvest), longer lead times, and price premiums versus conventional. Specialty grades — such as 'mi-zanshō' (young green pods) packed in salt or lightly blanched — are available seasonally and require chilled-chain handling.

Use cases

  • Shichimi tōgarashi seven-spice blend

    Positioning
    Heritage Japanese spice profile — sansho is one of the seven canonical components alongside chili, sesame, hemp/poppy seed, ginger, citrus peel, and nori. Blend dates to a 1625 Edo recipe at Yagenbori.
    Formulation notes
    Typical sansho proportion in a balanced shichimi is in the single-digit percent range; higher inclusion shifts the blend toward a tingling-forward profile suitable for noodles and yakitori finish.

    Sources

  • Unagi (grilled eel) finishing spice

    Positioning
    Traditional accompaniment — finely ground sansho is the canonical finishing pepper for kabayaki-style grilled eel, where its citrus-woody aroma cuts through the richness of the tare-glazed fish.

  • Specialty confectionery and chocolate

    Positioning
    Modern Japanese craft positioning — sansho is increasingly used by craft chocolate and confectionery makers as a single-origin Japanese spice, paired with dark chocolate, caramel, or matcha to deliver an unfamiliar tingling note in dessert applications.
    Formulation notes
    Sansho's volatile aroma compounds are heat-sensitive; powder is typically incorporated post-temper or in finishing dustings rather than in the main melt.
