When a customer or global brand asks a supplier to complete “Sedex”, a “SMETA Audit”, or even obtain a “SMETA certificate”, these terms are often treated as if they mean the same thing.
They do not.
Sedex provides a platform, tools, and solutions for managing responsible sourcing and supply chain sustainability data. SMETA – Sedex Members Ethical Trade Audit – is the social audit methodology developed and managed by Sedex.
Another important distinction is that SMETA is not a certification scheme and does not operate on a pass-or-fail basis. Instead, a SMETA audit provides information about actual workplace conditions, management systems, non-compliances, and areas requiring improvement.
This guide explains what Sedex and SMETA are, how they differ, the difference between SMETA 2-Pillar and 4-Pillar audits, what has changed under SMETA 7, how an audit is conducted, and what businesses should prepare before an assessment.
1. What Is Sedex?
Sedex is an organisation that provides a technology platform, tools, and solutions to help companies manage responsible sourcing, sustainability information, and supply chain risks.
Through the Sedex Platform, suppliers can maintain site information, complete self-assessment questionnaires, connect with customers, and share SMETA audit data with authorised business partners.
What Is the Sedex Platform Used For?
For suppliers, the Sedex Platform can be used to:
register and maintain company and site information;
complete the Self-Assessment Questionnaire – SAQ;
connect with customers and buyers;
manage and share SMETA audit information;
track responsible sourcing and sustainability-related information;
support supply chain due diligence activities.
Sedex itself does not conduct SMETA audits.
Official SMETA audits are carried out by auditors working for Sedex-approved Affiliate Audit Companies – AACs.

2. What Is SMETA?
SMETA stands for Sedex Members Ethical Trade Audit.
It is an audit methodology developed by Sedex to assess working conditions, labour practices, health and safety, environmental management, and business ethics at individual worksites.
SMETA draws on the principles of the ETI Base Code, relevant International Labour Organization – ILO conventions, and applicable local laws.
During a SMETA audit, auditors review not only policies and records but also actual workplace conditions, management systems, and information obtained from workers.
What Does a SMETA Audit Assess?
Depending on the selected audit scope, SMETA may cover:
Labour Standards
Recruitment, employment contracts, wages, working hours, child labour, forced labour, discrimination, freedom of association, worker treatment, and other employment conditions.
Health and Safety
Fire safety, machinery, personal protective equipment, chemicals, emergency preparedness, occupational health, workplace conditions, and related management systems.
Environment
Environmental permits, waste management, water, energy, chemicals, emissions, and other environmental management issues within a 4-Pillar audit.
Business Ethics
Anti-bribery, corruption, conflicts of interest, ethical business practices, and related management controls.
Labour Standards and Health & Safety form the core scope of SMETA, while Environment and Business Ethics are covered in greater depth under a 4-Pillar audit.
3. What Is the Difference Between Sedex and SMETA?
Sedex and SMETA are closely connected, but they are not interchangeable terms.
| Area | Sedex | SMETA |
|---|---|---|
| Nature | Organisation, platform and supply chain solutions | Social audit methodology |
| Main purpose | Manage, analyse and share supply chain information | Assess workplace conditions and management practices |
| Conducts audits | Sedex does not conduct audits directly | Audits are conducted by approved AAC auditors |
| Main output | Supply chain data and information | Audit Report, CAPR and findings |
| Certification | No | No |
| Pass/Fail | No | No |
In simple terms:
Sedex provides the ecosystem and platform; SMETA is the audit methodology.

4. Is SMETA a Certification?
Terms such as “SMETA certification” or “SMETA certificate” are commonly used in commercial discussions and online searches.
Technically, however, SMETA is not a certification programme.
After completing a SMETA audit, a company does not receive a Sedex certificate stating that it has “passed”.
Instead, the auditor records the conditions found at the site and documents relevant findings in the SMETA Audit Report and related corrective action documentation.
The buyer may then use this information together with its own supplier requirements, responsible sourcing policies, and risk criteria to determine appropriate follow-up actions.
When a customer asks for a “SMETA certificate”, the actual requirement may therefore be to:
complete a SMETA audit;
provide a recent SMETA Audit Report;
upload the audit to the Sedex Platform;
share the audit with the buyer;
address corrective actions identified during the audit.
5. What Are SMETA 2-Pillar and SMETA 4-Pillar Audits?
SMETA audits are commonly conducted using either a 2-Pillar or 4-Pillar scope.
SMETA 2-Pillar
A SMETA 2-Pillar audit focuses primarily on:
Labour Standards
Health & Safety
It also includes certain additional elements relating to entitlement to work, subcontracting, homeworking, and environmental assessment.
SMETA 4-Pillar
SMETA 4-Pillar expands the assessment by adding:
Environment
Business Ethics
This provides buyers with a broader view of social, environmental, and ethical risks at the site.
Whether a supplier requires a 2-Pillar or 4-Pillar audit normally depends on the buyer's responsible sourcing programme, risk profile, and specific customer requirements.

6. What Is SMETA 7?
SMETA 7 is the current generation of the SMETA methodology and represents a major evolution from earlier versions.
SMETA 7 places greater emphasis on identifying not only individual non-compliances but also the management systems and root causes behind workplace issues.
Key developments include the following.
Workplace Requirements
SMETA 7 introduces clearer Workplace Requirements to support more consistent assessment against the ETI Base Code and related requirements.
This allows auditors to determine more clearly whether specific workplace expectations are being met.
Management Systems Assessment – MSA
One of the most important developments in SMETA 7 is the Management Systems Assessment – MSA.
The auditor does not simply check whether a policy or procedure exists.
The assessment also considers factors such as:
policies and procedures;
management responsibility;
communication and training;
monitoring and evaluation of effectiveness.
This means that having well-written documents alone is not sufficient if the company cannot demonstrate that its systems are effectively implemented in practice.
Additional Data Points
SMETA 7 captures additional information that can help buyers and suppliers better understand workplace context and supply chain risks.
Collaborative Action Required – CAR
Some social or labour issues cannot be solved by the supplier alone.
SMETA 7 therefore introduced Collaborative Action Required – CAR for certain complex issues where effective remediation may require cooperation among suppliers, buyers, workers, and other stakeholders.
This reflects a broader shift towards continuous improvement and collaborative remediation rather than simply “closing findings”.
7. What Areas Does SMETA Assess?
A SMETA audit covers a wide range of workplace and management system issues.
Relevant Base Code Areas may include:
Enabling Accurate Assessment
The site must enable auditors to conduct an accurate and effective assessment.
Employment Is Freely Chosen
Employment must be voluntary and free from forced or compulsory labour.
Responsible Recruitment and Entitlement to Work
Recruitment practices and workers' legal entitlement to work are assessed.
Freedom of Association and Collective Bargaining
Workers' rights to association and collective representation are reviewed in the context of applicable law.
Health and Safety
Workplace safety, emergency preparedness, fire safety, machinery, chemicals, PPE, occupational health, and related systems are assessed.
Child Labour
The audit examines controls designed to prevent child labour and manage young workers appropriately.
Wages
Auditors review wages, deductions, benefits, payment practices, and relevant wage requirements.
Working Hours
Working hours, overtime, rest periods, and associated records are reviewed against applicable requirements.
Discrimination
Employment practices are assessed for discrimination and unequal treatment.
Regular Employment
The audit reviews whether employment arrangements appropriately reflect the actual working relationship.
Subcontracting and Homeworking
Controls relating to subcontracting and homeworking may also be reviewed.
Harsh or Inhumane Treatment
The audit examines issues such as harassment, abuse, disciplinary practices, and worker treatment.
For 4-Pillar audits, Environment and Business Ethics are assessed in greater depth.
In Vietnam, the auditor must also consider applicable Vietnamese legal requirements relevant to each assessment area.
8. What Is the Sedex SAQ?
SAQ – Self-Assessment Questionnaire is a questionnaire that a supplier completes on the Sedex Platform.
It collects information about the site's workforce, management systems, business activities, policies, and responsible sourcing practices.
The SAQ should not be treated merely as an administrative form.
Information entered in the SAQ should be accurate and consistent with actual site conditions and supporting records.
Significant differences between information declared on the platform and conditions identified during an audit may require further clarification.

9. What Is the SMETA Audit Process?
The detailed process may vary depending on the buyer, AAC, audit scope, and site circumstances, but a typical SMETA audit process includes the following steps.
Step 1: Confirm the Buyer's Requirements
The supplier should first determine:
whether a 2-Pillar or 4-Pillar audit is required;
whether the request is for a full or follow-up audit;
which site is within scope;
whether the buyer has additional programme-specific requirements;
the required timeline.
Step 2: Register and Maintain an Active Sedex Account
Businesses undergoing an official SMETA audit need to be registered on the Sedex Platform with an appropriate active membership.
Step 3: Complete Site Information and SAQ
The supplier updates its company and site profile, workforce information, and relevant self-assessment data.
Step 4: Select an AAC and Arrange the Audit
Official SMETA audits must be conducted by an Affiliate Audit Company approved by Sedex.
Sedex owns and manages the methodology but does not directly send its own auditors to conduct SMETA audits.
Step 5: Prepare for the Audit
The company reviews:
legal compliance;
management systems;
employment records;
payroll and working hours;
health and safety;
fire safety;
environmental management;
business ethics requirements;
actual workplace conditions.
Audit preparation should focus on identifying and addressing genuine compliance gaps rather than creating documents solely for the audit.
Step 6: Conduct the On-Site Audit
The auditor performs activities such as:
opening meeting;
site tour;
document review;
worker interviews;
management interviews;
data reconciliation;
closing meeting.
Step 7: Audit Findings and CAPR
Findings identified during the assessment are discussed at the closing meeting and documented in accordance with SMETA methodology.
Step 8: Corrective Action and Follow-Up
The company takes corrective action for identified findings.
Depending on the issue and buyer requirements, verification may involve documentary evidence or a follow-up audit.
