Finding the right factory is one of the most important decisions you'll make. Here's a practical checklist to help you separate professionals from amateurs.
1. Verify Certifications
GMP (Good Manufacturing Practice) is non‑negotiable.
ISO 22716 (cosmetics GMP), FDA registration, or Halal certification are strong signals of higher standards.
Ask for copies of certificates and verify them directly with the issuing bodies.
2. Assess R&D Capability
Do they have an in‑house R&D team? Can they develop a custom formula from scratch, or do they only offer pre‑made bases?
Can they adjust ingredients, concentrations, and textures to meet your brief?
Do they provide stability testing, preservative challenge tests, and safety assessments?
3. Production Equipment and Capacity
What formats do they specialise in? Softgels, liquids, creams, serums, masks?
What's their MOQ (Minimum Order Quantity)? Does it fit your budget and launch plan?
Can they support small‑scale trial runs before full production?
4. Quality Control Process
Ask about their QC workflow: incoming raw material inspection, in‑process checks, and finished product testing (microbial, heavy metals, active potency).
Do they retain batch samples and issue COAs (Certificates of Analysis) for every batch?
Are they open to third‑party inspections or audits?
5. Transparency and Communication
How quickly and clearly do they respond to your initial inquiries? This often reflects how they'll treat you later.
Are they willing to share factory tour videos or welcome on‑site visits? Reluctance is a red flag.
Are all costs (mould fees, sampling, shipping) clearly stated in the quote?
6. Samples and Testing
Always request product samples (some factories charge, some don't).
Test texture, scent, and performance yourself. If possible, run a small user trial.
Confirm their sample lead time and revision policy.
7. Client References and Experience
Ask for anonymised case studies or references from past clients.
Check online reviews or ask industry peers for feedback.
Ensure they understand regulations in your target markets (EU, US, ASEAN, etc.).
8. After‑Sales Support and Issue Resolution
What's their process if a batch has defects (leaks, contamination, unstable actives)?
Can they handle urgent re‑orders or rush production when needed?
