What Is a SMETA Audit? A Complete Guide for Suppliers

Introduction

If you supply goods to international brands, retailers, or sourcing companies, there’s a good chance you’ve come across the term “SMETA Audit” — often as a requirement from a buyer or customer rather than something you sought out on your own. For many suppliers, especially those new to social compliance, the term can feel unfamiliar and even a little intimidating.

In simple terms, SMETA stands for Sedex Members’ Ethical Trade Audit, an audit methodology used to assess how a business operates across four key areas: labour practices, health and safety, environmental practices, and business ethics. It’s one of the most widely recognised social compliance audit formats used across global supply chains today.

It’s worth noting upfront that not every business needs a SMETA Audit. Whether your company is required to complete one generally depends on your specific buyer, customer, or supply chain requirements — not on a fixed rule that applies to every exporter or manufacturer. This guide walks through what SMETA actually covers, how it works, and how suppliers can prepare with confidence.

What Is a SMETA Audit?

At its core, a SMETA Audit is a way for businesses and their buyers to assess workplace practices and responsible business conduct within a supply chain. Rather than being a certification you apply for and receive, SMETA is best understood as an audit methodology — a standardised way of reviewing how a company actually operates, based on documented evidence, physical site conditions, and worker feedback.

Buyers and brands use SMETA Audits to gain visibility into their supply chains: are workers treated fairly? Is the workplace safe? Are environmental and ethical standards being upheld? For suppliers, going through a SMETA Audit is less about ticking a compliance box and more about demonstrating that day-to-day operations genuinely reflect responsible business practices. You can find more detail directly from Sedex’s own overview of the SMETA methodology if you’d like to go deeper into the official framework.

The current SMETA methodology is SMETA 7.0, introduced in 2024, which provides updated guidance on audit scope, methodology, and specific workplace requirements.

This guide keeps things practical rather than diving into the full technical audit protocol — the goal is to help you understand what’s involved and how to approach it with clarity.

What Does a SMETA Audit Cover?

A SMETA Audit is built around four key areas, often referred to as “pillars.” Depending on the scope required by your buyer, you may be assessed against two or all four of these.

Labour Standards

This area looks at how workers are treated on a day-to-day basis, including working hours, wages, and freely chosen employment. Auditors typically review issues such as child labour, forced labour, discrimination, and whether workers’ rights — including freedom of association — are respected.

Health & Safety

This pillar focuses on the physical safety of the workplace. It covers occupational health measures, emergency preparedness (such as fire safety and evacuation procedures), and general workplace safety practices, from machinery guarding to protective equipment.

Environment

The environmental pillar examines how a business manages its environmental footprint. This can include energy use, waste management, chemical handling, and broader pollution prevention practices relevant to the nature of the business.

Business Ethics

This area looks at the integrity of how a business operates commercially, including anti-bribery and anti-corruption measures, and whether the company conducts itself ethically in its dealings with suppliers, customers, and authorities.

SMETA 2-Pillar vs 4-Pillar: What’s the Difference?

One of the most common points of confusion for suppliers is the difference between SMETA’s 2-Pillar and 4-Pillar audit scopes. The table below breaks down what each option covers:

It’s worth noting that 2-Pillar doesn’t mean environmental factors are ignored entirely — it already includes a simplified, basic environmental assessment. The 4-Pillar audit provides a broader scope, with a more comprehensive assessment of Environment and an additional Business Ethics pillar, on top of the core areas already covered under 2-Pillar.

It’s important to note that neither option is inherently “better” than the other. The appropriate scope depends entirely on what your buyer or customer requires. Some buyers may require a 2-Pillar assessment covering labour, health & safety, and basic environmental considerations, while others — particularly those with more stringent ESG or sustainability commitments — may require the broader 4-Pillar scope. If you’re unsure which applies to you, the right first step is to check directly with the buyer requesting the audit.

Who Needs a SMETA Audit?

SMETA requirements typically come from a company’s customer, buyer, or position within a supply chain, rather than being a general legal obligation. Businesses that commonly encounter SMETA requirements include:

• Manufacturing companies
• Suppliers and factories
• Export-oriented businesses
• Companies supplying international brands
• Businesses whose customers require social compliance assessments

A common misconception worth clarifying: exporting to Europe or the US does not automatically mean your company must complete a SMETA Audit. SMETA is not a government-mandated requirement tied to a destination market. Instead, the requirement is typically set by the specific buyer, brand, retailer, or supply chain customer you’re working with, as part of their own supplier due diligence or ethical sourcing programme.

If you haven’t been asked for one, it’s worth checking with your key customers or reviewing your contracts to see whether a social compliance audit — SMETA or otherwise — is expected as part of your ongoing business relationship.

What Happens During a SMETA Audit?

SMETA audits are conducted by independent third-party auditors from Sedex-approved Affiliate Audit Companies (AACs) — Sedex maintains the SMETA methodology itself but does not carry out audits directly.

While the exact process can vary slightly depending on the auditor and scope, a SMETA Audit generally follows five broad stages:

Step 1: Preparation

Before the audit, relevant requirements, internal policies, records, and general workplace conditions are reviewed to identify what documentation and information will be needed.

Step 2: Document Review

Auditors review records relevant to the areas being assessed — this typically includes labour records (such as payroll and working hours), health & safety documentation, and, where applicable, environmental and business ethics records.

Step 3: Site Assessment

The auditor conducts a physical walkthrough of the workplace to assess actual conditions and observe how relevant policies and procedures are implemented in practice — not just on paper.

Step 4: Worker Interviews

Auditors speak directly with workers, usually in a confidential setting, to better understand real workplace conditions and experiences from the employees’ own perspective.

Step 5: Findings & Corrective Actions

After the audit, findings are compiled and any areas requiring improvement are identified. Where applicable, corrective actions are discussed to help the business address gaps and strengthen its practices over time.

How Can Businesses Prepare for a SMETA Audit?

Good preparation makes a significant difference to how smoothly a SMETA Audit goes. Rather than treating it as a complicated or intimidating process, suppliers can approach it as a structured review of practices that are likely already partially in place. Some practical starting points include:

• Review labour policies and procedures
• Prepare employee and payroll records
• Check working hours and leave records
• Review workplace health & safety practices
• Review environmental practices relevant to your operations
• Check business ethics policies, including anti-bribery measures
• Identify potential gaps before the audit takes place

Going through this checklist ahead of time allows you to address obvious gaps early, rather than being caught off guard on the day of the audit itself.

How Is SMETA Connected to ESG?

SMETA sits within a broader framework that many businesses will recognise as ESG (Environmental, Social, and Governance). SMETA is not a formal sub-certification or official tier within ESG, but conceptually, the relationship can be understood through a simple chain:

ESG → Social → Social Compliance → SMETA

SMETA is particularly relevant to the Social component of ESG, as it directly assesses areas such as:

• Labour rights
• Human rights
• Workplace health & safety
• Responsible supply chains

For businesses that are increasingly asked about their ESG performance by investors, partners, or customers, understanding how SMETA fits into this bigger picture can be useful — though a deeper dive into ESG as a whole is a topic for another discussion.

SMETA and Other Social Compliance Audits

SMETA is one of several social compliance frameworks used across global supply chains. Depending on your industry and buyer requirements, you may also come across:

• SMETA (Sedex Members’ Ethical Trade Audit)
• RBA (Responsible Business Alliance, commonly used in electronics manufacturing)
• WRAP (Worldwide Responsible Accredited Production, common in apparel and textiles)

Different buyers may have different social compliance requirements depending on their industry, sourcing policies, and the standards their own customers expect. Understanding how these frameworks differ can help you avoid confusion — and avoid unnecessary duplication of effort — if you’re asked to comply with more than one.
