Quick answer
Before signing with any cosmetics OEM factory, get written answers to ten questions covering certification, formula exclusivity, what the price includes, who holds the NPRA notification, testing, timelines, minimum orders, reorders, failure handling and references. The answers — and how willingly they arrive in writing — will tell you more about the next twelve months of your brand than any brochure.
Key takeaways
- Every question below has a “good answer” pattern — compare factories on the same ten.
- Verbal answers are conversation; written answers are policy. Ask for email replies.
- The exclusivity question (No. 2) is the one most brand owners forget — and regret forgetting.
The 10 questions — and what good answers sound like
- “Can you show me your GMP certificate?”
A top factory sends it same-day with scope and validity visible. Hesitation here ends the shortlist. (Why it matters: GMP & NPRA explained.) - “Will my formula be manufactured for any other client?”
The honest answers are “yes, we fill shared bases” (private-label model) or “no — your formula is exclusive, and here is the clause.” OEM2YOU’s policy is the second: one brand, one formula. Whatever the answer, get it in the agreement. - “Exactly what does this quotation include?”
Look for an itemised list: formulation, sampling rounds, stability testing, packaging, artwork support, NPRA notification, delivery. “All-in” single numbers hide exclusions. - “Who files and who holds the NPRA notification?”
Either party can hold it, but you must know — it defines who controls the product’s market access. (Process: NPRA notification guide.) - “What testing is included, and in which packaging?”
Stability and compatibility testing in the final container is the professional norm — a formula tested in a lab beaker is not a tested product. - “What is the stage-by-stage timeline?”
A capable factory maps brief → sampling → packaging → testing → notification → production with weeks per stage. (Benchmarks: launch timeline guide.) - “What is the MOQ — and why?”
A factory that can explain its MOQ (batch sizes, raw-material minimums) is being straight; a suspiciously low MOQ usually means a shared base or a subcontractor. - “How do reorders work?”
Reorder lead time, price stability, and formula retention — your second production run matters more than your first. - “What happens if a batch fails QC?”
The good answer describes investigation, batch records and remake terms — without you paying for the factory’s failure. - “Can I speak to two clients in my category?”
References are the fastest truth-check in the industry. Protecting client confidentiality is fair; producing zero contactable references after years of operation is not.
How to run this as a comparison
Send the same ten questions to your shortlist of three factories in the same email format. Score each answer 0–2 (missing / partial / clear-and-written). The spread is usually dramatic — and the factory that answers fastest and clearest during courtship is almost always the one that communicates best during production.

Frequently asked questions
Is it rude to ask factories these questions?
No — serious manufacturers respect prepared clients. A factory annoyed by due diligence is answering question 10 for you.
What if I don’t understand an answer?
Ask for it in plain language. Inability to explain simply often signals the factory doesn’t control that step in-house.
Should I sign an NDA before sharing my product idea?
For a genuinely novel concept, a mutual NDA before detailed briefing is reasonable and normal.
