Sedex Audits: A Guide to SMETA 2 and 4-Pillar Audits (+ Free Templates)

The Supplier Ethical Data Exchange (Sedex) is a platform dedicated to enhancing transparency and accountability in supply chain operations. The Sedex Members Ethical Trade Audit (SMETA) is a comprehensive audit methodology (not a certification) designed to assess labor standards, health and safety, environmental performance, and business ethics across various industries.

SMETA 2 and SMETA 4 pillar audits are applicable across a broad spectrum of industries, including manufacturing, agriculture, food and beverage, apparel and textiles, pharmaceuticals, retail, logistics, hospitality, electronics, and chemicals. Sedex audits can enhance transparency across the supply chain, mitigate potential risks, ensure compliance with ethical standards, and build trust with consumers and partners.

This article will help you understand the scope and process of both SMETA 2 and SMETA 4 pillar audits, their importance in ensuring ethical supply chain practices, and the key differences between the two.

SEDEX SMETA Requirements: 4 Pillars of SMETA 

To align your operations with global ethical standards, understanding the Sedex SMETA 4 pillar framework is essential. Developed by Sedex, SMETA audits assess compliance across 4 critical areas: Labor Standards, Health & Safety, Environment, and Business Ethics. These SMETA 4 pillars are grounded in the Ethical Trading Initiative (ETI) Base Code and International Labour Organization (ILO) conventions, ensuring a comprehensive evaluation of ethical practices.

1. Labor Standards

It evaluates your adherence to fair labor practices, focusing on:

• Wages and Working Hours: Ensuring employees receive at least the minimum wage and work within legally mandated hours.
• Child and Forced Labor: Prohibiting employment of underage workers and any form of forced labor.
• Freedom of Association: Respecting workers’ rights to join unions and engage in collective bargaining.
• Non-Discrimination: Promoting equal opportunities regardless of race, gender, or other protected characteristics.

2. Health & Safety

The health & safety pillar examines the measures in place to protect workers’ well-being:

• Workplace Safety: Identifying and mitigating hazards to prevent accidents.
• Emergency Preparedness: Establishing procedures for emergencies, including fire drills and first aid.
• Sanitation and Hygiene: Maintaining clean facilities and access to potable water.
• Health Services: Providing necessary medical support and health education.

3. Environment

This pillar evaluates your organization’s environmental impact and sustainability efforts by reviewing environmental policies, monitoring data, and improvement plans:

• Resource Management: Efficient use of energy, water, and raw materials.
• Waste Management: Proper disposal and recycling practices to minimize pollution.
• Emissions Control: Reducing greenhouse gas emissions and monitoring air quality.
• Compliance: Adhering to environmental laws and obtaining necessary permits.

4. Business Ethics

This is the last SMETA pillar, which assesses the integrity of your business practices. It involves the evaluation of codes of conduct, training programs, and reporting mechanisms to ensure ethical operations.

• Anti-Corruption Measures: Implementing policies to prevent bribery and corruption.
• Transparency: Ensuring accurate record-keeping and honest communication.
• Confidentiality: Protecting sensitive information and respecting privacy.
• Fair Competition: Engaging in lawful and ethical competitive practices.

What is a SMETA Audit?

SMETA is a globally recognized audit methodology designed to assess and improve ethical and responsible business practices within supply chains. SMETA is one of the most widely used social audit formats in the world, helping organizations evaluate and enhance standards. 

There are two main types of Sedex SMETA audits, each varying in scope and depth.

SMETA 2 Pillar Audit

A SMETA 2 pillar audit focuses on two areas: labor standards and health & safety. It helps businesses identify and address ethical risks within their operations and supply chains. The SMETA 2 pillar audit can also include supplementary elements such as entitlement to work, homeworking, management systems, subcontracting, and a simplified environmental assessment.

Organizations across various industries may need a SMETA 2 pillar audit, particularly those:

• Supplying to retailers or brands that mandate ethical audits.
• Operating in regions with high risks related to labor and safety practices.
• Seeking to demonstrate commitment to ethical standards and improve supply chain transparency.

The timing for a SMETA 2 pillar audit depends on various factors:

• Client Requirements: If a client mandates an ethical audit, organizations should schedule it accordingly.
• Risk Assessment: Companies operating in high-risk regions or industries should consider regular 2 pillar SMETA audits to mitigate potential issues.
• Internal Policies: Organizations aiming to uphold high ethical standards may opt for periodic audits to ensure continuous compliance and improvement.

SMETA audit frequency for 2-pillar audits is typically annual or biennial, though this may vary based on specific organisational needs and stakeholder expectations.

SMETA 4 Pillar Audit

The SMETA 4 pillar audit is a comprehensive assessment framework designed to assess and improve a company’s ethical performance and evaluate its compliance with ethical trade practices across all four key areas discussed above.

• Labor Standards
• Health and Safety
• Environmental Management
• Business Ethics

SMETA 4 pillar audits are particularly relevant for:

• Companies with complex supply chains
• Exporters and suppliers
• Organizations committed to corporate social responsibility (CSR)

The necessity and frequency of SMETA 4 pillar audits depend on various factors:

• Customer or Buyer Requirements: Some clients may mandate regular audits to ensure ongoing compliance with ethical standards.
• Industry Standards: Certain industries may have specific guidelines dictating the need for periodic audits.
• Risk Assessment Outcomes: Companies may choose to conduct audits based on identified risks within their operations or supply chains.

To maintain compliance and address any identified issues, SMETA audit frequency for 4-pillar audits is generally annual or biennial too, depending on the company’s risk profile and stakeholder requirements.”.

What are the Main Differences Between 2-Pillar and 4-Pillar SMETA Audits?

While 2-pillar audits cover the basics, the 4-pillar audit offers a deeper, more structured approach across multiple dimensions of the Sedex audit process.

Aspect	SMETA 2-Pillar Audit	SMETA 4-Pillar Audit
Core Focus	Labor Standards, Health & Safety	Includes 2-pillar focus plus Environment and Business Ethics
Environmental Review	Simplified Assessment	Comprehensive Assessment
Business Ethics	Not Included	Included
Applicability	Suitable for organizations with limited environmental impact	Ideal for organizations with significant environmental and ethical considerations
Audit Depth	Foundational assessment	In-depth, comprehensive evaluation, making it more suitable for companies aiming for advanced sustainability and ethical standards

What’s New in SMETA 7.0?

SMETA 7.0 is Sedex’s current audit methodology, and it builds on SMETA 6.1 rather than replacing it outright. If you were audited under 6.1 or an earlier version, that audit remains valid; you don’t need an immediate re-audit, but any new audit will be carried out against 7.0.

The core of SMETA is unchanged: it’s still built on the ETI Base Code, still offered as a 2-pillar or 4-pillar audit, and still uses the same announced, semi-announced, and unannounced audit types. What SMETA 7.0 adds:

• Workplace Requirements: a more explicit breakdown of what auditors check against the ETI Base Code and local law, reducing the room for inconsistent interpretation between auditors.
• Management Systems Assessment: rather than only capturing a snapshot on the day of the audit, SMETA 7.0 scores how mature your underlying systems are for sustaining ethical practice, from “Not Addressed” to “Strong System.”
• Collaborative Action Required (CAR) findings: for issues too large for a single supplier to fix alone, such as living wage gaps, SMETA 7.0 calls for a joint response between buyer, supplier, and other stakeholders rather than placing the burden solely on the supplier.

SMETA 7.0 is still the current version; there’s no SMETA 8.0 in progress. What Sedex is doing right now is refining parts of 7.0 based on feedback since launch, running a consultation through Q1 2026 to adjust how Collaborative Action Required findings work in practice and to review its Issue Titles.

If you’re preparing for a 7.0 audit today, the methodology itself isn’t changing, only some of the finer implementation detail may be refined later in the year.

How to Prepare for Sedex Audits?

Here’s a step-by-step guide to prepare for on-site SMETA audits. 

1. Register with Sedex

Begin by registering on the Sedex platform. Choose the appropriate membership type (A or AB) based on your role in the supply chain. Upon registration, you will receive a Sedex Company Reference (ZC) number, which is essential for linking with your customers and accessing necessary tools like the self-assessment questionnaire (SAQ).

Sedex offers two main membership types: an A membership for suppliers, and an AB membership for organisations that are both a supplier and a buyer in the supply chain. Choose the one that matches your role before registering.

2. Link with Your Customers (Supplier Linking)

After registration, link your Sedex account with your customers by using their ZC numbers. This connection allows for the sharing of audit reports and SAQ responses.

3. Conduct a Gap Analysis

Perform a thorough gap analysis to identify discrepancies between your current practices and the requirements outlined in the Sedex audit criteria. It helps pinpoint areas that need improvement and ensure that you address potential non-compliances before the actual audit.

4. Complete the Sedex Self-Assessment Questionnaire (SAQ)

Access and complete the SAQ on the Sedex platform. The SAQ gathers information about your company’s operations, labor standards, health and safety practices, and environmental management systems. Ensure that your responses are accurate and reflective of your current practices, as this information will be reviewed by the auditor. 

5. Gather Necessary Documentation

Compile all relevant documents that demonstrate compliance with ethical standards, including employment contracts, payroll records, health and safety policies, environmental management procedures, training records, and any previous audit reports and corrective action plans. 

6. Brief Staff and Management

Educate your staff and management about the upcoming audit. Ensure they understand the purpose of the audit, what it entails, and their roles during the process. Conduct training sessions if necessary to prepare them for potential interviews and to reinforce the importance of compliance with ethical standards.

7. Choose a Sedex-Approved Auditing Company

Select an Affiliate Audit Company (AAC) approved by Sedex to conduct SMETA audits, ideally one accredited through APSCA. Ensure that the auditor is familiar with your industry and understands the specific requirements of your operations. Coordinate with the auditor to schedule the audit at a time when your facility is fully operational, as audits should be conducted during periods of peak activity. 

8. Determine the Scope: 2-Pillar or 4-Pillar SMETA Audit

Decide whether you require a 2-pillar SMETA audit or a 4-pillar audit. The choice depends on your customer’s requirements and the nature of your business operations. 

9. Conduct a Pre-Audit

Before the official audit, consider conducting an internal pre-audit to assess your readiness. It helps in identifying any remaining gaps and allows you to address them proactively. Review your SAQ responses, verify the availability and accuracy of documentation, and ensure that staff is prepared for the audit process.

On-Site Sedex Audit Process

Let’s take a closer look at what the actual Sedex audit process looks like. 

1. Opening Meeting

The Sedex audit commences with an opening meeting involving the site’s management and, where applicable, employee representatives. During this session, the auditor outlines the audit’s scope, objectives, and methodology, referencing standards such as the ETI Base Code and relevant local laws. The meeting also confirms logistical details, including the audit schedule, required documentation, and arrangements for site access and employee interviews. 

2. Site Tour

Following the opening meeting, the auditor conducts a comprehensive tour of the facility. It covers all operational areas, including production zones, storage areas, employee amenities, and, if applicable, worker accommodations. This is done to observe working conditions firsthand, assess health and safety measures, and verify compliance. 

3. Documentation Review

The auditor then examines relevant documentation to assess the site’s adherence to labor and ethical standards. Key documents include employment contracts, payroll records, working hour logs, health and safety policies, training records, and any permits or licenses required by law. It helps corroborate observations from the site tour and provides evidence of the site’s compliance with applicable standards. 

4. Worker and Management Interviews

Interviews are conducted with both management and a representative sample of workers. Management interviews focus on understanding the site’s policies, procedures, and management systems. Worker interviews, conducted confidentially, aim to gather insights into actual working conditions, treatment by management, and awareness of rights and grievance mechanisms, validating information obtained through documentation and observation. 

5. Closing Meeting

At the conclusion of the audit, a closing meeting is held with management and, where appropriate, employee representatives. The auditor presents the findings, highlighting areas of compliance and non-compliance. A corrective action plan report is prepared to ensure that the site understands the audit outcomes and the steps required for continuous improvement. 

What if an on-site visit isn’t possible?

For sites where physical access is restricted, for example due to location, travel restrictions, or urgency, a Sedex Virtual Assessment is an option, using video conferencing to connect an approved auditor with the site remotely. It covers the same core areas as a standard audit and produces a Sedex-recognised report.

Sedex’s own guidance still recommends an in-person audit whenever site conditions allow, so treat a virtual assessment as an exception rather than a permanent substitute.

What to Do After a Sedex Audit?

Once the Sedex audits have been completed, here’s what you need to do.

1. Prepare and Submit the Audit Report and Corrective Action Plan (CAPR)

Upon receiving the audit report, review it thoroughly to understand the findings. Collaborate with your audit firm to develop a corrective action plan report (CAPR) that outlines specific actions to address each non-compliance issue, responsible parties, and timelines. Once finalized, upload both the audit report and the CAPR to the Sedex platform.

2. Address Non-Conformities

Implement the corrective actions as detailed in the CAPR. This may involve revising policies, enhancing training programs, or improving workplace conditions. Engage with your team to ensure that these changes are effectively integrated into daily operations. Regularly monitor progress and document evidence of improvements to demonstrate compliance.

3. Conduct Follow-Up Audits if Required

Depending on the severity of the non-conformities, a follow-up audit may be necessary to verify the implementation of corrective actions. Schedule this audit in coordination with your audit firm and ensure that all remedial measures are in place beforehand. The follow-up audit will assess the effectiveness of the actions taken and confirm compliance with SMETA standards.

4. Maintain Ongoing Compliance

Establish internal mechanisms to regularly review and update your practices in line with ethical standards. Use the Sedex platform to monitor compliance status, track improvements, and share updates with stakeholders. Engage in continuous training and development programs to foster a culture of ethical responsibility within your organization.
