For first-world buyers, supplier due diligence is no longer a CSR nicety. EU due-diligence rules, UK and Australian modern slavery reporting and US forced-labour enforcement all put the burden on the importer, not the factory. If you manufacture in Thailand, you own the evidence.
What regulators actually ask for
| Requirement area | Evidence buyers must hold | Refresh cycle |
|---|---|---|
| Labour and recruitment | Contracts in workers' language, no recruitment fees, passport-retention policy | Annual |
| Working hours and pay | Payroll and time records sampled, overtime consent | Annual audit, quarterly spot check |
| Health and safety | Permits, machine guarding, PPE, incident log | Annual |
| Environment | Wastewater and emissions permits, waste contractor licence | Annual |
| Traceability | Tier-2 material origin, mill or farm level where required | Per programme |
Thailand's manufacturing base includes a large migrant workforce, which is exactly where recruitment-fee and document-retention findings appear. Treat those two items as mandatory checks, not sampling items.
Building an audit programme that is proportionate
- Risk-tier your suppliers — spend, process hazard, workforce composition and destination-market rules.
- Use one standard — SMETA, SA8000 or your own protocol, but the same one everywhere so results are comparable.
- Combine with quality — a joint quality and social audit halves travel cost. Our factory audit checklist covers the quality half.
- Require corrective action plans with dates — findings without owners and deadlines are documentation, not remediation.
- Verify closure on site, not by email photograph.
Traceability beyond tier one
Your Thai assembler may be flawless while a tier-2 material supplier is the exposure. Ask for a bill of materials mapped to named upstream sources for anything regulated: metals, cotton and textiles, rubber, palm derivatives, seafood and electronics components. Put the disclosure obligation in the contract — the clause belongs in your supply agreement.
Cost and cadence
An independent third-party social audit of a mid-size Thai plant is a modest cost against the value of a compliant supply chain, and far cheaper than a detained shipment. Fold the result into the same quarterly review as your supplier scorecard so commercial and ethical performance sit on one page.
Documentation you should be able to produce within one working day
- Current audit report and corrective action status per supplier
- Signed supplier code of conduct
- Tier-2 traceability declaration for regulated materials
- Records of any grievance raised and how it was resolved
- Your own risk assessment methodology
If a customs authority or an enterprise customer asks and you cannot produce this, the shipment stops while you look for it.
Frequently Asked Questions
Do EU due-diligence rules apply to a small importer buying from Thailand?
Thresholds vary by regulation and company size, but enterprise customers and retailers push the same requirements down the chain contractually. In practice most exporters to the EU need the evidence regardless of whether the statute applies directly.
Which social audit standard is most accepted for Thai factories?
SMETA four-pillar is the most widely recognised among Thai exporters, with SA8000 and BSCI also common. Pick one standard and apply it consistently so year-on-year comparison is possible.
What are the most common findings in Thai factory social audits?
Recruitment-fee and migrant-worker documentation issues, excessive overtime records, incomplete machine guarding, and missing or expired environmental permits.
How often should social audits be repeated?
Annually for tier-one suppliers, with unannounced or semi-announced spot checks for higher-risk sites and any supplier with open critical findings.
Does an audit protect me from a forced-labour detention?
It reduces risk and gives you evidence, but detention decisions turn on traceability of the material itself. Combine the audit with documented tier-2 origin records for regulated inputs.
