Understanding SEDEX: The World’s Largest Ethical Trade Platform
The Supplier Ethical Data Exchange (Sedex) was established in 2004 in the United Kingdom by a coalition of leading global brands seeking a shared solution to supply chain risk management. Today, Sedex operates as the world’s largest collaborative platform for sharing responsible sourcing data, connecting over 85,000 members across 180+ countries and storing more than 1.5 million supply chain datasets.
Sedex operates on a simple but powerful principle: “Audit once, share many.” Rather than hosting multiple separate inspections for each buyer, a supplier completes one SMETA audit and publishes the report on the Sedex Advance platform, where it becomes accessible to all linked Member A (buyer) accounts simultaneously. This dramatically reduces audit fatigue and duplication costs for both suppliers and buyers.
The Sedex Membership Structure
| Member A | Buyers, brands & retailers (e.g. global FMCG, fashion, automotive). They access the platform to monitor supplier risk and review SMETA reports from their supply chain. |
| Member B | Suppliers & service providers — factories, warehouses, logistics companies. This is where Vietnamese businesses sit. Member B completes the SAQ and undergoes SMETA audit. |
| Member AB | Organisations that are both buyers of inputs and sellers of outputs — common in mid-tier supply chains. |
| AAC | Approved Audit Companies: independent third-party auditors authorised by Sedex to conduct official SMETA audits. Examples: Bureau Veritas, SGS, Intertek, Control Union, Staunchly Management & System Services. |
| ⚠️ Critical Distinction: Sedex does NOT issue certificates like ISO. The outcome of a SMETA audit is a detailed audit report published on Sedex Advance — buyers read it and make their own commercial decisions. A clean report with strong Good Practices and all NCs closed on time is your competitive advantage. |
What Is SMETA? A Deep-Dive into the Audit Methodology
SMETA — Sedex Members Ethical Trade Audit — is the standardised audit protocol, measurement criteria, and reporting format that all AACs must follow when evaluating a supplier site. Currently at version 7.0 (SMETA Measurement Criteria v7.0), SMETA provides a globally consistent framework that allows a report from a warehouse in Ho Chi Minh City and one from a factory in Bangladesh to be read and compared on equal terms by the same international buyer.
The ETI Base Code: SMETA’s Ethical Foundation
All SMETA assessments are grounded in the Ethical Trading Initiative (ETI) Base Code — nine principles for protecting workers’ rights, safety, and dignity — cross-referenced against applicable local law (Vietnam Labour Code 2019, Law on Occupational Safety & Health 2015, Decree 145/2020/ND-CP, and current regional minimum wage regulations).
| # | Nguyên tắc ETI / ETI Principle | Nội dung cốt lõi / Core Requirement |
| 1 | Lao động tự nguyện / Freely Chosen Employment | Không cưỡng bức, không giữ giấy tờ, không đặt cọc giữ việc |
| 2 | Tự do hiệp hội / Freedom of Association | Quyền gia nhập công đoàn, thương lượng tập thể |
| 3 | An toàn & Vệ sinh lao động / Health & Safety | Môi trường làm việc an toàn, PPE, đào tạo ATSK ⭐ Trọng tâm kho lạnh |
| 4 | Không lao động trẻ em / No Child Labour | Tối thiểu 15 tuổi (VN law + ILO), bảo vệ lao động trẻ (≤ 18) |
| 5 | Lương đủ sống / Living Wage | Lương ≥ mức tối thiểu vùng, hướng tới lương đủ sống |
| 6 | Giờ làm việc hợp lý / Working Hours | Tổng ≤ 60 giờ/tuần, OT tự nguyện, ≥ 1 ngày nghỉ/7 ngày ⭐ Rủi ro OT |
| 7 | Không phân biệt đối xử / No Discrimination | Tuyển dụng, thăng tiến, lương bình đẳng không phân biệt |
| 8 | Đối xử nhân văn / Humane Treatment | Cấm xúc phạm, đe dọa, quấy rối, phạt tiền kỷ luật |
| 9 | Hợp đồng lao động / Regular Employment | Hợp đồng văn bản, đúng loại, ký trước khi làm việc |
| The Higher Standard Principle: When Vietnamese law and the ETI Base Code differ on a specific requirement, SMETA always applies whichever offers greater protection to workers. Example: Vietnamese law caps overtime at 40 hours/month; if a worker actually worked 50 hours of OT, this violates Vietnamese law — and the auditor will record it as a Non-Conformance regardless of the ETI weekly cap. |

NC Classification: How Auditors Grade Findings
Every finding is classified into one of five severity levels. Understanding this system is essential for prioritising pre-audit preparation and post-audit remediation:
| Mã | Tên | Mô tả / Description | Hành động / Action |
| BC | Business Critical | Nguy cơ ngay lập tức tới tính mạng, an toàn hoặc nhân quyền NLĐ. Imminent risk to life, safety or human rights. | Xử lý ngay + CAP trong 7 ngày / Immediate + CAP within 7 days |
| CR | Critical | Vi phạm nghiêm trọng Bộ quy tắc/luật, cần xử lý khẩn. Serious breach requiring urgent action. | Ưu tiên cao / High-priority remediation |
| M | Major | Vi phạm rõ ràng Bộ quy tắc hoặc luật. Clear breach of code or law. | Khắc phục ≤ 90 ngày / Remediate ≤ 90 days |
| C | Core / Minor | Sai lệch nhỏ hoặc thiếu hệ thống quản lý. Minor deviation or management-system gap. | Theo kế hoạch / Planned remediation |
| S | Screening | Câu hỏi xác định phạm vi — không xếp hạng NC. Scope-defining — not ranked as NC. | Không áp dụng / Not applicable |
| Key Insight: A Business Critical (BC) finding such as a blocked fire exit or unresolved refrigerant leak must be addressed on the day of the audit. Buyers are notified immediately and may suspend orders until the BC is closed and verified. |
The SMETA Audit Process: Three Phases
Pre-Audit (Preparation): Sedex registration → SAQ completion → gap assessment → document preparation → site improvement → worker awareness
On-site Audit: Opening meeting → site walk → worker interviews (confidential) → records review (triangle cross-check: timesheet ↔ payroll ↔ interview) → closing meeting → preliminary CAPR
Post-Audit (Follow-Through): Report upload to Sedex → Publish → CAPR implementation → Desktop Audit or Follow-up Audit → NC closure → ongoing annual SAQ maintenance
| Typical Total Timeline: 3–6 months from first preparation to published report. A well-prepared site can complete the full cycle in 10–12 weeks. Annual SAQ update required every year to keep the account “In Date”. |
SMETA and the Regulatory Landscape: Why It Is No Longer Optional
A combination of buyer pressure and binding legislation is making SMETA participation effectively mandatory for Vietnamese exporters:
- Germany’s Supply Chain Due Diligence Act (Lieferkettensorgfaltspflichtengesetz / LkSG, effective 2023): German companies with 1,000+ employees must conduct human rights and environmental due diligence across their entire supply chain — and document it. SMETA is a widely accepted evidence standard.
- EU Corporate Sustainability Due Diligence Directive (CSDDD, 2024): Extends similar obligations to EU companies, cascading requirements down to all tiers of supplier relationships.
- UK Modern Slavery Act & EU Forced Labour Regulation: Require proactive identification and remediation of forced labour risks — directly mapped to SMETA ETI 1.
- Buyer Scorecards (EcoVadis, CDP, GRI-aligned questionnaires): International buyers increasingly score suppliers on ESG — and SMETA audit evidence provides some of the strongest possible documentation.

Service 3 — Pre-Audit Consulting & GAP Assessment
Our consultants conduct a structured GAP Assessment benchmarked against SMETA 7.0 Measurement Criteria. Deliverables include:
- Written GAP Assessment Report mapped to each requirement code (01.01.001 through 11.01.004)
- Prioritised CAP with BC/Critical items flagged for immediate remediation
- Document checklist and evidence preparation guide
- Sedex SAQ review and data reconciliation (including GHG inventory alignment)
- Mock worker interview preparation — ensuring workers know their rights without coaching
Service 4 — Certification Support & Post-Audit NC Closure
- Liaising with Sedex-approved AACs (including our affiliate Staunchly Management & System Services) for official audit scheduling
- CAPR drafting support with 5-field corrective action documentation
- Root-cause analysis using 5 Whys methodology to prevent NC recurrence
- Evidence compilation and Sedex Advance upload (policies, certificates, GHG reports)
- Annual SAQ maintenance to keep the account audit-ready year-round
SMETA and EcoVadis: Maximum ROI on Your Compliance Spend
- Labour & Human Rights: SMETA report + closed CAPR = verified implementation → maximum EcoVadis scoring
- Environment: SMETA 4-Pillar data + GHG inventory = comprehensive environmental evidence package
- Business Ethics (hardest to score): SMETA Pillar 4 ABC policy and whistleblowing documentation closes this gap
