FAQ before ordering Cosmetics OEM
General points that buyers commonly ask before ordering {industry} OEM. For each manufacturer's specific terms, please refer to their official website.
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.
