Global buyers increasingly expect suppliers to provide clear information about labour practices, health and safety, environmental management and business ethics. For suppliers working with international brands, retailers, manufacturers and other buyers, meeting these expectations can become an important part of maintaining business relationships.
Sedex membership gives suppliers a platform to manage and share responsible business information with customers. Suppliers can complete their profile and Self-Assessment Questionnaire (SAQ), share relevant information with buyers and use audit results to support Sedex and ethical supply chain management
A SMETA audit (Sedex Members Ethical Trade Audit) provides an on-site assessment of areas such as labour standards, health and safety, environmental performance and business ethics. SMETA audits are conducted by Sedex-approved Affiliate Audit Companies. Importantly, Sedex membership and SMETA are not certifications and SMETA does not operate on a traditional pass-or-fail basis.

What Is Sedex Membership for Suppliers?
Sedex is a platform that helps suppliers collect, manage and share information about responsible business practices with their customers. Supplier membership provides access to the Sedex platform, where businesses can maintain company and site information, complete assessments, share audit results and communicate relevant information with buyers.
For suppliers, Sedex can help reduce repeated requests for similar information from different customers. Instead of preparing separate information for every buyer, businesses can maintain their information on the platform and share it with selected customers.
Sedex membership can therefore support suppliers that want to:
- Improve supply chain transparency
- Organize responsible sourcing information
- Respond to buyer requirements
- Share audit information with customers
- Identify areas requiring improvement
- Strengthen ongoing compliance practices
Why Do Buyers Ask Suppliers to Join Sedex?
International buyers need reliable information about the suppliers they work with. They may want to understand how a supplier manages labour conditions, workplace safety, environmental responsibilities and business ethics.
Sedex gives buyers access to supplier information through a centralized platform and can help reduce duplicated questionnaires and assessments. For suppliers, this can make it easier to respond to customer requests and demonstrate how responsible business practices are managed.
Buyer requirements can vary depending on the industry, country, product, risk level and individual customer. A supplier should therefore review the specific requirements communicated by each buyer rather than assuming that Sedex membership alone satisfies every requirement.
What Is a SMETA Audit?
SMETA (Sedex Members Ethical Trade Audit) is an audit methodology developed and stewarded by Sedex to assess working conditions and responsible business practices at a specific site. It covers areas including labour standards, health and safety, environmental performance, and business ethics.
The 2-Pillar SMETA audit covers Labour Standards and Health & Safety, while the 4-Pillar SMETA audit also includes Environment and Business Ethics. Sedex currently identifies SMETA 7 as its latest version.
During the audit, an approved auditor may review policies, records, workplace conditions, processes, and worker information to identify good practices and areas requiring corrective action.

SMETA 2-Pillar vs 4-Pillar Audit
Suppliers should understand the scope requested by their buyer before preparing for a SMETA audit.
SMETA Audit | Main Areas Covered | Typical Focus |
2-Pillar | Labour Standards; Health & Safety | Working conditions, wages, working hours, worker rights and workplace safety |
4-Pillar | Labour Standards; Health & Safety; Environment; Business Ethics | Wider responsible sourcing, environmental controls and ethical business practices |
The appropriate scope depends on buyer expectations and the supplier’s circumstances. Sedex notes that most buyers now choose the full 4-Pillar audit.
What Should Suppliers Prepare Before a SMETA Audit?
Good preparation starts well before the auditor arrives. Suppliers should review their policies, records, workplace practices and legal obligations to identify potential gaps.
Preparation Area | What Suppliers Should Review |
Labour and Employment | Employment contracts, working hours, wages, leave records, worker documentation, recruitment practices and controls against forced or child labour |
Health and Safety | Emergency procedures, fire safety, PPE, machinery safeguards, accident records, risk assessments, first aid and safety training |
Environmental Management | Waste, energy and water use, emissions, wastewater, chemical controls, environmental permits and monitoring records |
Business Ethics | Anti-bribery controls, conflict-of-interest procedures, ethical policies, reporting channels and business conduct |
Records and Evidence | Training records, inspection reports, payroll records, maintenance records, permits, monitoring data, corrective actions and internal reviews |
How Suppliers Can Prepare for Sedex and SMETA
Suppliers can approach Sedex compliance as a series of practical steps rather than waiting until a buyer requests an audit.
1. Register as a Sedex Supplier:
The first step is to establish the appropriate supplier membership and create the required business and site information on the Sedex platform.
2. Complete the Self-Assessment Questionnaire:
The Self-Assessment Questionnaire (SAQ) provides information about the organization’s responsible business practices. Suppliers should ensure that responses are accurate, current and supported by appropriate evidence.
3. Review Compliance Gaps:
After completing the relevant information, businesses should identify areas where policies, controls, records, or workplace practices need improvement.
4. Prepare for the SMETA Audit:
If a buyer requires a SMETA audit, the supplier should prepare the workplace, documents, employees and relevant records according to the required audit scope.
5. Complete the Audit:
SMETA audits are conducted by Sedex-approved Affiliate Audit Companies. The auditor assesses the site against the applicable SMETA methodology and reviews relevant workplace conditions, documentation, processes and practices.
6. Address Corrective Actions:
Audit findings can identify areas where improvements are needed. Suppliers should develop corrective actions, assign responsibilities, establish timelines and maintain evidence of completed improvements.
7. Maintain and Share Updated Information:
Sedex should be treated as an ongoing supply chain management process. Businesses should keep their information current and share relevant information with buyers as required.
Common Sedex Compliance Gaps Suppliers Should Check
Many supplier issues are not caused by the absence of policies but by inconsistent implementation or incomplete evidence.
Common areas to review include:
- Missing or outdated employee records
- Incomplete working-hour or payroll records
- Insufficient workplace risk assessments
- Weak emergency preparedness
- Inadequate worker training records
- Poor waste or chemical management
- Missing environmental monitoring records
- Incomplete supplier controls
- Weak grievance or reporting mechanisms
- Inconsistent corrective-action follow-up
Identifying these issues before an audit gives the business an opportunity to improve its practices and organize supporting evidence.

How Suppliers Can Prepare Employees for SMETA
Employees play an important role in demonstrating how workplace procedures operate in practice. Preparation should therefore not be limited to management or compliance staff.
Employees should understand:
- Their workplace health and safety responsibilities
- Relevant company policies
- Emergency procedures
- Working-hour and leave arrangements
- Available grievance or reporting channels
- Environmental responsibilities relevant to their work
- How to provide accurate information during an audit
Businesses should avoid preparing employees with scripted answers. The objective should be to ensure that employees understand actual workplace practices and can communicate honestly about their experience.
Managing Corrective Actions After a SMETA Audit
A SMETA audit should not be treated as the end of the compliance process. Where findings are identified, suppliers should focus on addressing the underlying causes.
A practical corrective-action approach can include:
- Understand the finding clearly.
- Identify the underlying cause.
- Define the corrective action.
- Assign responsibility.
- Set a realistic completion date.
- Collect evidence of implementation.
- Review whether the action has been effective.
This approach helps suppliers move from simply responding to findings toward continual improvement.
Sedex and Ethical Supply Chain Transparency
Sedex can support broader responsible supply chain management by helping businesses organize and share information about labour practices, health and safety, environmental performance and business ethics.
Suppliers can use Sedex to:
- Improve supply chain transparency by maintaining relevant responsible business information.
- Share information with buyers about workplace practices, policies and audit results.
- Identify areas for improvement across labour, health and safety, environmental and ethical practices.
- Support ongoing responsible sourcing by keeping information and corrective actions updated.
