A factory audit in Vietnam costs $240 to $400 per man-day; a basic one-day audit runs $300 to $400. It checks quality, labour, fire safety and security before your first PO. Run the 12-point checklist and insist on ISO/IEC 17020 and APSCA credentials.

Why audit a Vietnamese factory before you buy?
Vietnam’s manufacturing base has never been bigger. GDP reached US$514 billion in 2025 and exports hit US$470 billion. Manufacturing value-added grew 9.97 percent year on year, the fastest annual rate of the 2019 to 2025 cycle.
Disbursed FDI touched a five-year high of US$27.6 billion. The S&P Global Manufacturing PMI closed the year at 53.0, after eight straight months of expansion.
The catch: factory quality systems have not kept pace with that growth. In the audits we run across Ho Chi Minh City, Binh Duong and Bac Ninh, three Critical findings recur: blocked fire exits, payroll that does not match timecards, and hidden subcontracting. A structured audit closes that gap.
Per dollar of order value, the case for auditing in Vietnam is stronger than in China.
What types of factory audits are conducted in Vietnam?
Five audit types cover most sourcing needs. You rarely need all five. The right scope depends on your product, your destination market and what your buyer demands.
| Audit type | Main standards | What it verifies |
|---|---|---|
| Social compliance | SMETA 4-pillar, SA8000, amfori BSCI, WRAP | Wages, overtime cap (200 hrs/yr), minimum age 15, health and safety |
| Environmental & fire safety | ISO 14001, Decree 08/2022, Decree 136/2020, QCVN 06:2022/BXD | Wastewater, EIA, fire permit (PCCC), exits |
| Capability & capacity | Extensive Factory Audit | Headcount, monthly output versus your MOQ |
| Technical / quality | ISO 9001:2015, AQL sampling | Calibration, defect tracking, in-line QC |
| Security | C-TPAT, TAPA, ISO 28000 | Personnel screening, container 7-point check, seal log |
How much does a factory audit in Vietnam cost?
Vietnam audit pricing in 2026 sits at USD 240 to 400 per man-day, all-inclusive. Cost climbs with factory size, remote location, scope and weekend surcharges. Vietnam audits run 30 to 50 percent higher than equivalent audits in China, because the country has fewer accredited auditors per capita.
| Audit scope | Duration | Typical cost (USD) |
|---|---|---|
| Basic general audit | 1 day | 300 to 400 |
| In-depth social or environmental | 1 to 2 days | 700 to 1,000 |
| SMETA 4-pillar (medium factory) | 2 to 5 days | 2,500 to 4,000 |
| Man-day rate, all-inclusive | per day | 240 to 400 |
For orders under US$10,000, a one-day evaluation is usually enough. For orders above US$100,000 or US-bound apparel and electronics, combine a SMETA 4-pillar and a C-TPAT check in the same visit.
What happens during a factory audit?
The day follows the same backbone whatever the audit type, only the focus changes. The most requested is the social compliance audit. It checks wages, working hours, the overtime cap, worker safety, and the absence of forced or underage labour.
After 10,000+ hours auditing Vietnamese factories, here is how Jeremy, our lead auditor in Ho Chi Minh City, runs a social compliance audit.
| Time | Step |
|---|---|
| 8:00 | Opening meeting with factory management |
| 8:30 to 11:30 | Document review: payroll, contracts, permits |
| 11:30 to 13:00 | Floor walk: fire exits, PPE, machine safety |
| 14:00 to 16:00 | Confidential worker interviews, off the floor |
| 16:00 to 16:30 | Payroll versus timecards cross-check |
| 16:30 | Closing meeting and same-day draft findings |
Findings are classified Critical, Major or Minor, with photo evidence and root-cause notes. The factory signs a corrective action plan with deadlines under 60 days, and a re-audit verifies closure. The full report follows within 48 hours.
Factory audit Vietnam checklist
Use this 12-point checklist on every new supplier before your first order. The payroll cross-check (item 5) is what catches forced overtime and underage labour.
- Business licence, tax code and export licence, with GPS-verified factory address.
- Org chart, total headcount, shift structure and monthly capacity versus your order.
- 5M1E review across the production line.
- ISO 9001, 14001 and 45001 certificates, plus product certs (FSC, CARB), validated on the issuing body’s portal.
- Payroll cross-checked against timecards and social-insurance filings.
- Fire exits unblocked and labelled, QCVN 06:2022 compliance, PCCC permit on file.
- Environmental and wastewater discharge permit under Decree 08/2022 (amended by 05/2025).
- Confidential worker interviews covering at least 10 percent of the workforce.
- Subcontracting register showing which steps are outsourced and to whom.
- Sample traceability from raw-material lot to finished-goods carton.
- C-TPAT items for US-bound goods: container 7-point inspection, seal log, visitor log.
- Corrective action plan signed by the GM, with SMART actions and deadlines under 60 days.
The payroll cross-check against social-insurance filings is the single highest-yield test. It catches the forced overtime and underage labour that staged audit-day conditions are designed to hide.
How do you vet a Vietnam audit provider?
Two credentials are non-negotiable. The audit body should hold ISO/IEC 17020 accreditation for inspection competence and impartiality. Individual social auditors should be APSCA-registered. APSCA oversees 84 member firms and over 5,300 auditors worldwide, and you can scan an auditor’s digital membership QR code on arrival.
Avoid firms that quietly subcontract audits to freelancers. The 2016 Nike-Hansae Vietnam case is the warning: third-party auditors missed forced overtime and unsafe conditions until independent groups re-audited. A credible partner holds both credentials and returns a full report within 48 hours.
Factory audit in Vietnam vs China
| Dimension | Vietnam | China |
|---|---|---|
| Average manufacturing wage | ~US$3/hr | ~US$6.50/hr |
| Audit cost (man-day) | $240 to $400 | 30 to 50% lower |
| QMS and IP maturity | Growing, thinner mid-management | Deeper, more standardised |
| Social-compliance readiness | Strong, driven by EVFTA | Mixed |
| Tariff access via FTAs | EVFTA, CPTPP, UKVFTA, RCEP | Few comparable |
Factory audit vs product inspection: how often should you audit?
An audit and an inspection are not the same. A factory audit checks systems, people and process before tooling starts. A product inspection checks finished goods against spec at three points: during production, before shipment, and at container loading. Serious buyers run both.
Audit every new supplier before the first PO. Re-audit low-risk suppliers once a year. For high-risk categories like apparel and electronics, run social and environmental audits quarterly.
One caveat from experience: an audit is a snapshot. Some factories tidy up for the visit, then slip back. We counter this with unannounced re-audits on high-risk sites.
