Supplier codes of conduct
A supplier code of conduct is a formal set of standards a business requires its suppliers to follow
It typically covers areas such as labour rights, health and safety and environmental practices
The purpose and value of a supplier code of conduct
Sets clear, consistent expectations for all suppliers
This reduces the risk of misunderstanding the standards required
Helps protect a business's reputation
Customers and other stakeholders increasingly expect ethical practices throughout the supply chain
Reduces legal and reputational risk
A supplier found breaching laws, such as on labour rights, can seriously damage the business that buys from it
Provides a business with clear grounds to end a relationship with a supplier that seriously breaches agreed standards
A typical supplier code of conduct
Labour standards
Suppliers must not use child labour or forced labour, and must pay at least the legal minimum wage
Working hours
Employees must not be required to work more hours than permitted by local law, and must receive appropriate rest breaks
Health and safety
Suppliers must provide a safe working environment, including appropriate safety equipment and training
Environmental standards
Suppliers must comply with local environmental laws and take reasonable steps to reduce waste and pollution
Anti-discrimination
Suppliers must not discriminate against employees on the basis of gender, race, religion or disability
Right to audit
Suppliers must allow the business, or an independent third party acting on its behalf, to inspect premises and records to check compliance
Supplier audits
A supplier audit is a formal check, carried out by a business or an independent third party, to verify that a supplier is actually complying with the agreed standards
A code of conduct sets out expectations in writing, but an audit is what confirms whether a supplier is genuinely following it in practice, since agreeing to a code does not guarantee compliance
Example
A clothing retailer requires all its suppliers to sign a code of conduct banning child labour and setting minimum safety standards, then sends independent auditors to visit factories unannounced to check that working conditions match what has been agreed
Purpose and value of supplier audits
Verifies that a supplier is genuinely meeting the standards in the code of conduct, rather than simply agreeing to them on paper
Helps identify problems early, before they escalate into a serious ethical or legal issue that could damage the business's reputation
Provides evidence a business can show to customers, investors or regulators that it takes ethical sourcing seriously
Encourages continuous improvement
Regular audits can highlight areas where a supplier needs to make changes over time
Case Study
Marlow Lane
Marlow Lane is a clothing retailer that sources most of its garments from factories in South and East Asia.
Following criticism of the wider fashion industry over poor factory conditions, Marlow introduced a supplier code of conduct requiring every factory it worked with to meet minimum standards on wages, working hours and health and safety.
To check the code was being followed, Marlow commissioned independent audits of its suppliers' factories, including unannounced visits.
During one audit, inspectors found that a long-standing supplier was requiring staff to work far more overtime than permitted under the code, without paying the agreed rate.
Marlow gave the supplier three months to make changes and carried out a follow-up audit to confirm the issue had been resolved before continuing to place orders.
Setting up the auditing programme was costly and added time to Marlow's supplier onboarding process, and some smaller suppliers struggled to meet the administrative demands of regular inspections.
However, Marlow was able to use its ethical sourcing programme in its marketing, and reported an increase in sales from customers who said ethical sourcing influenced their choice of retailer
