Supply Chain Due Diligence
Supply chain due diligence is the process by which a business identifies, prevents, mitigates and accounts for adverse social and environmental impacts in its supply chain. Far from a passive compliance exercise, it is an active and ongoing risk management framework. For procurement professionals, this means systematically investigating and addressing potential and actual harms related to human rights, labour standards and environmental protection connected to your company’s purchasing activities.
Why it matters
For procurement leaders, mastering supply chain due diligence has become essential for operational resilience and strategic risk management. As legislative frameworks like the EU’s Corporate Sustainability Due Diligence Directive (CSDDD) and Germany’s Supply Chain Act (LkSG) become more common, a robust due diligence process is no longer optional — it is a core business function with significant legal and financial implications.
A strategic approach to supply chain due diligence is vital to:
- Ensure legal compliance: Adhering to mandatory due diligence laws is paramount. An effective process protects your organisation from substantial fines, civil liability, and exclusion from key markets, ensuring your licence to operate.
- Mitigate profound business risks: Due diligence uncovers critical vulnerabilities before they escalate. Issues like forced labour, unsafe working conditions, or environmental violations can lead to sudden factory shutdowns, delivery failures, and reputational crises. Proactively managing these risks ensures business continuity.
- Enhance brand reputation and trust: Stakeholders, from investors to consumers, now demand transparency and hold businesses accountable for their supply chains. Demonstrating credible due diligence builds trust and provides a powerful competitive differentiator.
- Drive supplier performance and resilience: The process fosters deeper collaboration with suppliers. By setting clear expectations and working together on improvement plans, you can build stronger, more reliable partnerships founded on shared values, which enhances overall supply chain performance.
How it works / key points
The first step is to formally commit to responsible business conduct. This involves creating a clear policy statement and integrating due diligence responsibilities into relevant business functions, particularly procurement. This ensures accountability is defined and embedded throughout the organisation.
Organisations must gain visibility into their supply chains to understand where the most severe risks lie. This involves mapping suppliers and using a risk-based approach — analysing country, sector and site-specific data — to prioritise action. The goal is to identify the most salient risks so resources can be focused effectively.
Once risks are identified, action is required. This stage involves implementing measures to prevent potential harm and address existing issues. Key activities include enforcing supplier codes of conduct, seeking contractual assurances, investing in supplier capacity building, and developing and tracking corrective action plans to remedy identified violations.
Due diligence is an ongoing process. It is crucial to monitor the effectiveness of your actions over time. This means tracking the progress of corrective actions, verifying that improvements are sustained, and regularly re-assessing risks to ensure your interventions are delivering tangible, positive outcomes.
The final stage is transparency. This involves publicly reporting on your due diligence efforts—the risks you found, the actions you took, and the results you achieved. Clear communication, backed by credible data, demonstrates accountability to regulators, investors, and other stakeholders.
Examples
An electronics company identifies a high risk of workplace accidents in a region where key components are sourced. As part of its due diligence, the company makes a SMETA audit a mandatory step in its supplier onboarding process for that region. It then uses its leverage to ensure suppliers with identified hazards create and implement a time-bound corrective action plan to address issues such as inadequate machine guarding or insufficient safety training.
A global coffee brand, in response to due diligence requirements, invests in a supply chain due diligence solution to map its supply chain back to the cooperative level. This increased visibility helps identify risks of child labour and deforestation. The company then provides training and resources to specific cooperatives to help them implement safer, more sustainable farming practices.
Following a site audit, a procurement manager for an automotive parts supplier discovers that a Tier 2 supplier has inadequate machine guarding, posing a significant safety risk. The procurement team works with the Tier 1 supplier to ensure a corrective action plan is implemented at the Tier 2 facility, tracking progress through photographic evidence and follow-up verification to confirm the risk is mitigated.
