Supplier Qualification Process
Initial Qualification
- Request sample + COA
- Verify COA meets all critical specifications
- Conduct sensory evaluation (visual, odour)
- If pilot testing, submit for independent verification
- Approve supplier and add to Approved Supplier List
Ongoing Monitoring
- Review COA for every lot received
- Track any out-of-spec trends
- Re-qualify annually or after any quality issue
- Maintain at least two approved suppliers for critical anchors
- Include psyllium and fibre base COAs in the per-lot review process due to their impact on process consistency and GI tolerance

Feb 2026 |
Expanded scope to cover Functional Pack fibre ingredients. Added Section 7 (Psyllium Husk) and Section 8 (Fibre Base — Pumpkin Powder / Carrot Fibre). Standardised all dosing notes to reference Production Master Spec rather than hardcoded inclusion rates. Tightened kelp iodine range from 500–1,500 mg/kg to 800–1,200 mg/kg. Updated rejection criteria for kelp to match tightened range. Added psyllium + fibre base to Supplier Qualification ongoing monitoring. Purpose section updated to clarify fibre ingredient coverage. |
