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.
What shelf-life can be set for food products?
Depends on format and sterilization. Typical targets: retort foods 1–2 years, frozen 1 year, refrigerated 30–90 days, ambient baked goods 90–180 days. Shelf-life is fixed after stability testing (microbial and sensory).
Can allergen labeling and ingredient specs be accommodated?
Yes. Most manufacturers manage the 8 mandatory + 20 recommended allergen items, and some operate gluten-free, dairy-free, or vegan dedicated lines. Share any required ingredient specs in the quote request.
Are HACCP or food-safety certifications in place?
HACCP is mandatory for Japanese food manufacturers, so nearly all listed partners operate HACCP or equivalent systems. You can also filter for upper-tier certifications such as FSSC 22000, ISO 22000, JAS, or Organic JAS.
