SEDEX SMETA 4-Pillar Audit Preparation SOP

SMETA stands for Sedex Members Ethical Trade Audit. Sedex is the Supplier Ethical Data Exchange, an online platform where garment factories share ethical trade information with their buyers. When a factory completes a SMETA audit, the report is uploaded to Sedex and can be shared with every buyer linked to that factory site. That sharing is the reason SMETA preparation matters so much: one audit result is visible to many buyers at once, for better or worse.

A SMETA audit assesses a factory against the ETI Base Code and local labour law, applying whichever standard is stronger. The audit comes in two scopes. A 2-pillar audit covers Labour Standards and Health and Safety. A 4-pillar audit adds two further pillars: Environment and Business Ethics. Buyers specify the scope, and the factory must confirm it before preparation starts, because a factory prepared only for two pillars will be caught short on environmental records and ethics policies when a 4-pillar auditor arrives.

This lesson gives a complete preparation SOP for a SMETA 4-pillar audit in a Bangladesh garment factory. It follows the same logic auditors use: documents first, site second, workers third, and corrective action last.

Labour Standards covers freely chosen employment, freedom of association, safe and hygienic working conditions, no child labour, living wages, working hours, no discrimination, regular employment, and no harsh or inhumane treatment. These are the nine clauses of the ETI Base Code, and they are examined through contracts, payroll, time records, and worker interviews.

Health and Safety covers building safety, fire safety, machine guarding, personal protective equipment, chemical handling, and worker training. Auditors walk the floor, test whether exits are clear, check extinguisher and hydrant certificates, and ask workers whether they know evacuation routes.

Environment covers legal environmental compliance, waste management, water use, energy use, and emissions. For a garment factory this usually means environmental clearance documents, hazardous waste disposal slips, and effluent treatment plant monitoring records.

Business Ethics covers anti-bribery and fair business practice. Auditors look for a written anti-bribery policy, a gift and hospitality register, and evidence that managers and relevant staff have been briefed. A factory with no ethics policy at all will raise a finding under this pillar even if its labour and safety performance is strong.

Preparation follows a fixed sequence, and skipping a step creates risk later.

First, the factory completes the Sedex self-assessment questionnaire, known as the SAQ. The SAQ must be honest and complete, because auditors compare SAQ answers against site evidence. A factory that claims full overtime compliance in its SAQ and then shows mismatched time records will face a credibility problem on top of the overtime finding.

Second, the audit body is confirmed. The buyer usually approves or nominates the audit firm, which must be qualified to conduct SMETA audits. Confirm the audit dates, the number of auditors, the languages needed, and which site areas and worker groups are in scope.

Third, the factory assembles its document pack, indexed by pillar, so that any document can be produced within minutes during the audit. Auditors typically review the last twelve months of payroll and time records, so the pack must cover a full year, not just the last month.

Fourth, the factory runs internal cross-checks: payroll against time cards against production records; fire and building certificates against expiry dates; environmental slips against waste actually generated. Every mismatch found internally is a finding prevented.

Fifth, the site is prepared: evacuation routes cleared, safety equipment serviced, chemical storage labelled, and a private interview room set up away from the production floor. The interview room must be genuinely private, with no management presence and no line of sight from supervisors.

Sixth, management and workers are briefed honestly: an audit is coming, interviews are confidential, and no worker will face retaliation for speaking truthfully. This briefing is also the moment to state clearly that no one should coach workers on answers.

Seventh, the audit itself runs over its scheduled days: opening meeting, site tour, document review, worker interviews, and a closing meeting where findings are presented. The factory then submits a corrective action plan, or CAPA, for every finding, with root cause, corrective action, responsible person, deadline, and evidence. Findings close only when evidence is accepted, not when a promise is made.

The document pack decides most of the audit outcome before the auditor reaches the factory floor. For Labour Standards, prepare employment contracts, age verification records, twelve months of payroll and time records, leave records, wage slips, and grievance logs. For Health and Safety, prepare the fire licence, building safety and structural certificates, evacuation drill records, PPE issue logs, and the accident register. For Environment, prepare environmental clearance, waste disposal contracts and slips, and effluent treatment monitoring reports. For Business Ethics, prepare the anti-bribery policy, conflict-of-interest declarations, and ethics training records.

Two rules govern the pack. Every document must be original or a true copy, and every date must be current. An expired fire certificate is worse than a missing one in one respect: it proves the factory knew the requirement and let it lapse. If a document genuinely does not exist, say so and show what does exist instead. Never create a document after the auditor asks for it.

An export knitwear factory in Gazipur, supplying three European buyers through Sedex, received its first SMETA 4-pillar audit date with five weeks of notice. A quick internal check found three problems: overtime hours on time cards did not match overtime paid for one sewing line, two fire extinguisher certificates had expired, and the factory had no written anti-bribery policy for the Business Ethics pillar.

The compliance manager organised preparation into weekly sprints. Week one reconciled payroll against time records for every line and paid the shortfall found on the sewing line. Week two renewed all fire safety certificates and cleared two partially blocked evacuation routes. Week three drafted, approved, and briefed an anti-bribery and business ethics policy to managers and commercial staff. Week four ran a full mock audit, including worker interviews in the private room, conducted by an internal team that had not prepared the documents.

The real audit raised only minor non-compliances, all closed within the agreed CAPA period. Because the SMETA report is shared on Sedex, all three buyers accepted the same report instead of each commissioning a separate audit, saving the factory repeated disruption and repeated audit cost.

The most severe recurring finding is disagreement between records: time cards, payroll sheets, and production records telling different stories about the same workers hours. Prevention is a monthly three-way reconciliation, signed off by HR and production together.

Blocked or locked emergency exits are a critical safety finding. Prevention is a weekly exit inspection routine with a named owner and a log, not a pre-audit cleanup.

Missing or expired safety certificates are easy to prevent with a certificate expiry calendar reviewed monthly by the compliance team.

Coaching workers before interviews is an integrity violation. Prevention is a clear management instruction, repeated in the pre-audit briefing, that workers answer truthfully and that no retaliation will follow.

A missing business ethics policy is a common 4-pillar surprise. Prevention is a short, real policy: what counts as a bribe, what gifts are allowed, who to report concerns to, and evidence that staff were briefed.

Thirty days before the audit, confirm scope, audit body, and dates, and complete or update the SAQ. Twenty-one days before, assemble the document pack and start the payroll-versus-time reconciliation. Fourteen days before, renew any expiring certificate and clear every evacuation route. Seven days before, run the mock audit, fix what it finds, and brief managers and workers honestly. On audit day, provide access, documents, and a private interview room, attend the closing meeting without arguing findings, and begin the CAPA the same week.

SMETA 4-pillar audit preparation is a documentation and systems exercise, not a cleaning exercise. Factories that reconcile their own records every month, maintain safety and environmental evidence year-round, protect interview confidentiality, and close findings with genuine root causes pass audits and keep the shared Sedex report working for every buyer on the platform. The next lesson examines the labour standards pillar in depth: forced labour, child labour, and freedom of association.
