We designed a four-stage progressive screening protocol for topsheet suppliers: Stage 1 filters by basic fiber specifications, Stage 2 retests surviving candidates under controlled conditions, Stage 3 runs blind comparison against the target benchmark, Stage 4 validates cost competitiveness. Each stage eliminates roughly half the candidates, so resources are concentrated on the highest-potential options.

Why Only CORIO
Most sourcing processes are two-stage: get samples, pick the cheapest. Our four-stage funnel invests more upfront to avoid costly mistakes downstream.
