Supplier code of conduct
A supplier code of conduct is a documented set of environmental, social, ethical, and business-behaviour expectations that an organization communicates to suppliers. It may form part of contracts and supplier management, but it becomes effective only when supported by risk-based due diligence, engagement, monitoring, purchasing practices, corrective action, and remedy.
In simple terms
A code commonly addresses labour and human rights, health and safety, environmental management, integrity, and compliance with applicable law. It should explain scope, responsibilities, reporting channels, and consequences, and it should be understandable to the suppliers expected to implement it. The code is one tool within a wider responsible sourcing system. Organizations still need to identify and prioritize actual and potential impacts, involve relevant stakeholders, examine how their own purchasing decisions contribute to risk, support improvement, track outcomes, and enable remediation where appropriate.
Why it matters
A clear code can align baseline expectations across a supply network and give procurement teams and suppliers a common reference. Where CSDDD applies, publishing a code alone does not satisfy the directive's due diligence duties. Used alone, a code can shift responsibility downstream or encourage paperwork without better outcomes. Its credibility depends on governance, supplier dialogue, risk-sensitive assessment, realistic commercial terms, responsible disengagement, grievance channels, corrective action, and evidence that harms are addressed.
Example
A buyer includes its supplier code in onboarding, translates it where needed, and trains procurement staff on the same expectations. It uses risk information to focus assessment, gives a supplier time and support to correct unsafe conditions, adjusts purchasing practices that contributed to the problem, consults affected workers, and verifies whether conditions improve.
How it differs
Responsible sourcing
Responsible sourcing is the broader practice of integrating impact and risk considerations into purchasing and supplier relationships; a supplier code of conduct is one document used to communicate expectations within that practice.
