Scenario: How should CTIP be implemented for multi-tier supplier networks?

• A. Rely solely on self-reporting without audits.
• B. Only audit the first-tier suppliers and ignore sub-tier suppliers.
• C. Use flow-down clauses to all tiers, require supplier attestations, conduct on-site audits, and monitor through risk-based approaches.
• D. Ban all subcontracting to avoid complexity.

Answer: (C)

Implementing CTIP across a multi-tier supplier network requires a comprehensive, verifiable framework that flows down through all tiers and uses audits and risk-based monitoring. Flow-down clauses embedded in contracts ensure the same CTIP expectations apply to every supplier, from primary vendors to sub-tier providers, creating clear, enforceable obligations across the entire network. Requiring supplier attestations formalizes commitment and creates a documented trail that suppliers acknowledge and stand behind, which helps in accountability and due diligence.

On-site audits are essential to verify actual practices and uncover issues that attestations alone cannot reveal, such as indicators of trafficking, forced labor, coercive recruitment, or exploitative conditions. When combined with risk-based monitoring, you focus resources where risk is greatest—geographies, industries, or supplier tiers with higher trafficking indicators—allowing timely remediation and continuous improvement without overextending oversight.

Relying solely on self-reporting provides no independent verification, auditing only first-tier suppliers misses exploitation that can occur deeper in the chain, and banning subcontracting is often impractical and does not address the root risk. The flow-down, attestations, audits, and risk-based monitoring approach creates a proactive, scalable, and enforceable CTIP program aligned with modern supply-chain realities.
