Client: Canadian air-filter manufacturer (hospitals & institutions) – NDA
Destination: Canada (with USA compliance considerations)
SHAMANA services: Sourcing, documentation review, sample management, corrective actions, second-source qualification, engineering change & PPS, commercial optimization (TCO)
Timeline: Round-1 rejected (odor) → Round-2 passed → 23 mm base change → PPS approved → commercial renegotiation/TCO
Status: Initial purchase order — 500 units
Commercial impact: ~50–60% unit price reduction vs. the client’s initial European source (like-for-like spec & compliance)
The challenge
The client needed UV lamps with strict specifications and full CA/US documentation. Round-1 samples passed datasheet checks but showed odor/outgassing. After round-2 success, a fit requirement led to reducing the base to 23 mm. Once resolved, the client also sought a cost reduction to improve commercial viability.
Our approach
Confirmed technical and compliance requirements.
Resolved odor issue with Supplier A.
Qualified Supplier B in parallel.
Sent round-2 samples (A + B) — both passed.
Selected supplier with strongest compliance.
Engineering change: reduced base to 23 mm with tooling adjustments.
Produced PPS to 23 mm spec — approved.
Commercial optimization & TCO: compared qualified factories, reviewed BoM, leveraged batch size, and validated savings using a landed-cost model (unit price + freight + duties).
Results
~50–60% unit price reduction vs. client’s previous European source.
Total cost of ownership validated with logistics/duty assumptions.
0 rejections in round-2.
2 qualified suppliers.
First PO: 500 units.
Odor issue resolved.
Engineering change implemented (23 mm base).
PPS approved.
What we learned / tips
Validate savings on a TCO (landed-cost) basis, not just factory price.
Document assumptions so savings can be audited internally.
Keep compliance equivalence explicit when comparing across regions.
