Company History of Inuiu Eiyou Kagaku Co., Ltd.
- —
Founded in 1855 (Ansei 2) as a traditional herbal medicine wholesaler in Dōshōmachi, Osaka under the trade names "Ōmi-ya" and subsequently "Inui Ui," the company was inherited by Inui Uibei I in 1880. The Namba Factory was established in 1905 for licorice root processing, followed by the Sakai Factory in 1911 for mosquito coil manufacturing. In 1913, a Dalian branch office was opened, and the Dalian Factory began operations in 1914 for licorice extract production and export. Inui Ui Shōten Corporation was incorporated in 1917, followed by the establishment of Inui Ui Food Products Co., Ltd. in 1921. The company began manufacturing and selling the bath additive "Onsense" in 1933, and changed its corporate name to Inui Ui Eiyō Kagaku Co., Ltd. in December 1934.

Common Pre-Order Questions
Frequently asked questions from buyers before placing an OEM order. Manufacturer-specific details can be confirmed via a quote request.
What are typical minimum order quantities (MOQ)?
MOQs vary by manufacturer, but listed partners handle anything from small lots (100–1,000 units) up to large-scale production (100,000+). The lower bound depends on raw material sourcing and packaging specs, so confirm exact MOQs in your quote request.
How long does it take from quote to delivery?
Quote replies typically take 3–7 business days. From there, mass-production delivery (including prototyping) generally takes 2–4 months. New formulation development or certification work can extend this past six months. Final schedule is set during the quote phase.
Are prototype or sample fees charged?
Most manufacturers charge for prototypes (typically a few hundred USD up), but the cost is often credited back once mass production is confirmed. Existing-formula samples are sometimes free. Policies vary, so confirm in advance.
Can we sign an NDA?
Yes, generally. Quote requests routed through OEM JAPAN can be covered by an NDA before formulation or recipe details are shared. Either the manufacturer's or the buyer's NDA template can be used.
Will the manufacturer help with PMDA (cosmetics) filings?
Manufacturers licensed as cosmetic marketing-authorization holders typically assist with manufacturing notifications and ingredient-label review. Quasi-drugs (medicated cosmetics) require a separate approval process with longer lead times.
Will stability (use-by) testing be performed?
Yes. Accelerated tests (40°C / 3 months) and long-term tests (25°C / 6–12 months) are commonly run to set the use-by period. Cost ranges from several hundred to several thousand USD depending on test items; minimum duration is roughly 3 months.
What container and filling formats are supported?
Tubes, bottles, jars, pouches, sprays, and airless containers are widely supported. Sample-size fills and material specifications (PET, glass, aluminum, etc.) are usually negotiable — confirm in the quote request.
