Vietnam Factory Audit Checklist: What to Verify Before Placing an Order
A factory audit is how you confirm that a Vietnamese supplier can actually deliver what they promised before you wire any money. Unlike product inspections, which check finished goods during and after production, a factory audit evaluates the supplier itself: legal registration, production capacity, quality systems, and working conditions. Most audits cost $300 to $500 for a standard assessment and can be arranged remotely through a third-party auditor in as little as 48 hours.
This guide covers what to include in your audit checklist, the main audit types, their costs, and how to interpret results so you can make a confident sourcing decision.

What a Factory Audit Actually Verifies (and What It Does Not)
A factory audit and a product inspection are two different things that happen at two different stages of the sourcing process.
A factory audit evaluates the supplier itself: their facility, their systems, their people, and their ability to produce your product consistently over time. It happens before you place an order.
A product inspection evaluates the actual goods being manufactured: checking finished units against your spec sheet using AQL sampling. It happens during and after production. If you need guidance on inspections, AQL, defect classification, and building a QC plan, see our quality control in Vietnam guide.
This guide focuses entirely on the audit side: verifying the factory before you commit.
Specifically, a factory audit in Vietnam should verify:
Legal status: Is the company registered and licensed to manufacture and export? Does their business license match their claimed company name and address?
Physical facility: Does the factory exist at the stated location? Is it a real production facility or a trading company operating out of an office?
Production capacity: Does the factory have the equipment, floor space, and workforce to handle your order volume within your timeline?
Quality management: Are there documented quality control procedures? Do they have incoming material checks, in-process controls, and final inspection protocols?
Certifications: Does the factory hold relevant certifications (ISO 9001, BSCI, OEKO-TEX, SA8000, etc.) and are those certifications current?
Working conditions: Are employees working in safe conditions consistent with Vietnamese labor law and international standards?
If you are still in the process of identifying potential factories, start with our guide on how to find manufacturing companies in Vietnam before scheduling audits.
When You Need a Factory Audit
Not every order requires a formal audit, but certain situations make it essential.
Always audit when:
You are working with a new supplier for the first time and have not visited the factory yourself.
Your order value exceeds $10,000 or involves tooling/mold investment.
The supplier was found online (Alibaba, Made-in-Vietnam, etc.) and you have no independent verification of their legitimacy.
You are producing a regulated or safety-critical product (children's items, electronics, food-contact materials).
Your end buyer (retailer, distributor) requires supplier compliance documentation.
An audit is optional but recommended when:
You have an existing supplier relationship but have never verified conditions on the ground.
You are scaling order volume significantly with a current factory.
Your product category has changed and you need to confirm the factory's capability for the new item.
You can likely skip the audit when:
You have personally visited and vetted the factory.
A trusted sourcing company has vetted the supplier on your behalf with documented evidence.
You are placing a small trial order (under $2,000) specifically to test the supplier before committing.
The Four Main Audit Types
Factory audits in Vietnam generally fall into four categories. Most buyers only need the first one or two. Social and environmental audits are typically required by large retailers or brands with formal compliance programs.
Supplier Qualification Audit (SQA)
Cost: $300 to $400
This is the standard pre-production audit and the one most buyers should start with. An SQA verifies the basics: legal registration, physical presence, production equipment, workforce size, and general capability. The auditor visits the facility, reviews documentation, photographs the production floor, and delivers a report confirming whether the factory is what it claims to be.
An SQA answers the core question: "Is this a real, capable factory that can produce my product?"
Extensive Factory Audit (EFA)
Cost: $350 to $500
An EFA goes deeper into technical capability. Beyond confirming that the factory exists and is licensed, the auditor evaluates production processes, quality management systems, equipment calibration records, defect tracking, and capacity utilization. An EFA is the right choice when you need to confirm the factory can meet specific technical requirements or when you are comparing multiple qualified suppliers on capability.
An EFA answers: "Can this factory consistently produce my product to the quality level and timeline I need?"
Social Compliance Audit (CSA)
Cost: $800 to $1,000
A CSA evaluates labor practices, worker safety, and working conditions against standards like SMETA (Sedex), BSCI, WRAP, or SA8000. Auditors interview employees, review payroll and timekeeping records, inspect dormitories (if applicable), and assess fire safety, emergency preparedness, and overall facility conditions.
CSA audits are typically required when selling to major retailers (Walmart, Target, Costco) or European brands with supply chain compliance mandates. If your buyer has not specifically required a social audit, an SQA or EFA is usually sufficient.
Environmental Audit (EA)
Cost: $700 to $1,000
An EA assesses the factory's environmental impact: waste management, chemical handling, water and energy consumption, emissions, and compliance with Vietnamese environmental regulations. These audits are most relevant for industries with significant environmental exposure (textiles with dyeing processes, tanneries, chemical manufacturing) or when your brand makes environmental sustainability claims.
Your Pre-Order Factory Audit Checklist
Whether you hire a third-party auditor or visit the factory yourself, use this checklist to make sure you cover every critical area. This is the checklist we use internally at Cosmo Sourcing when vetting factories for clients, and it reflects what we have learned from visiting hundreds of Vietnamese factories since 2014.
1. Legal and Business Verification
Business registration certificate (confirm company name, registration number, and address match)
Cross-check against Vietnam's National Enterprise Registration Portal if possible
Export license (required for direct export)
Tax registration certificate
Confirm the legal representative's name matches who you have been communicating with (or is the actual owner/director)
Red flag: The company cannot or will not produce a business license. The name on the license does not match the company name you were given. The registered address is different from the factory address with no explanation.
2. Facility and Equipment
Factory is at the stated address and is a genuine production facility (not an office, warehouse, or showroom)
Production floor layout is organized and appropriate for the product type
Equipment is operational, reasonably maintained, and suitable for your product
Equipment age and condition (older machines are not automatically a problem, but poorly maintained ones are)
Sufficient floor space and workstations for the claimed production capacity
Red flag: The "factory" is clearly a trading company office. Equipment is idle or visibly broken. The facility looks recently staged (borrowed equipment, empty tool racks, freshly painted floors with no wear).
3. Production Capacity
Number of production lines and workers per line
Current production load and available capacity for new orders
Typical lead times for products comparable to yours
Whether the factory subcontracts any production steps (and if so, to whom)
Past production volumes for similar products (ask for examples)
Red flag: The factory claims capacity far exceeding what the facility and workforce could support. They refuse to discuss subcontracting. Their claimed lead times are unrealistically fast for the product complexity.
From our experience, many small and mid-sized Vietnamese factories operate at 70% to 90% capacity. If a factory says they have unlimited availability, that is usually either inaccurate or a sign they are planning to outsource your order.
4. Quality Management Systems
The audit is not the place to evaluate how good the factory's QC process is in detail. That is what product inspections are for. But the audit should confirm that the factory has quality systems in place at all.
Is there a dedicated QC team or at least a designated quality person?
Written quality control procedures (even basic ones)
Evidence of incoming material checks
Evidence of in-process and final checks (documented, not just claimed)
Defect tracking and corrective action records
Equipment calibration records (for relevant machinery)
Sample retention policy
Red flag: No QC personnel on-site. No written procedures of any kind. The factory has never heard of AQL (Acceptable Quality Level) standards. They cannot show you any records of defect tracking.
5. Certifications and Compliance
ISO 9001 (quality management) or equivalent
Product-specific certifications relevant to your market (CE, UL, FDA, OEKO-TEX, CPSIA, etc.)
Verify that certifications are current and issued by accredited bodies (not self-declared)
Social compliance certifications if required (BSCI, WRAP, SMETA, SA8000)
Red flag: Certifications are expired. The factory claims ISO certification but cannot produce the certificate. The certification was issued by an unknown or unaccredited body.
6. Working Conditions (Basic Assessment)
Even if you are not conducting a full social compliance audit, any factory visit or audit should include a basic assessment of working conditions:
General cleanliness and housekeeping
Adequate lighting and ventilation
Fire exits are clearly marked, unblocked, and sufficient for the number of workers
Basic safety equipment is available (fire extinguishers, first aid kits, PPE where required)
Workers appear to be of legal working age
No visible signs of unsafe conditions (exposed wiring, blocked exits, hazardous material storage issues)
Red flag: Fire exits are locked or blocked. Workers are not wearing required PPE. The factory tries to restrict which areas you can see.
7. References and Track Record
Ask the factory for references from other international buyers (particularly from your target market)
Request examples of products they have manufactured that are similar to yours
If possible, verify export history through trade data or shipping records
Red flag: The factory claims to work with major brands but cannot provide any verifiable references. They have no samples or production examples to show.
How to Arrange a Factory Audit in Vietnam
You have three options for getting an audit done:
Option 1: Hire a third-party audit company. This is the most common approach for buyers who are not based in Vietnam. Companies like V-Trust, QIMA, Bureau Veritas, Pro QC, and others have full-time auditors stationed across Vietnam's manufacturing regions. You book the audit online, specify what you need, and receive a detailed report (usually within 24 to 48 hours of the visit). For a full list with contact details, see our list of inspection and audit companies in Vietnam.
Option 2: Use your sourcing agent. If you are working with a sourcing company in Vietnam, factory vetting and audits are typically part of their service. A good sourcing company will visit the factory, verify the basics, and provide you with photos and a written assessment. The depth of this varies by company, so make sure you are clear about what you expect them to check.
Option 3: Visit the factory yourself. If your order size justifies the trip, there is no substitute for walking the production floor in person. You will pick up on things an audit report cannot capture: how the factory manager responds to questions, how organized the workflow is, how workers interact, and whether the overall feel of the operation matches what you were told. If you do visit, bring the checklist above.
What Factory Audits Cost in Vietnam
Audit pricing in Vietnam is straightforward. Most third-party audit companies charge a flat day rate:
Standard SQA/EFA audit: $300 to $500 per man-day
Social compliance audit (CSA): $800 to $1,000 per man-day
Environmental audit (EA): $700 to $1,000 per man-day
A standard supplier qualification audit typically takes one man-day and covers one factory location. More complex audits (multi-building facilities, combined audit types) may require additional time.
Vietnam audit pricing runs about 20% to 40% higher than comparable audits in China. The reason is simple: China has far more competition among QC companies, which drives prices down. Vietnam's audit industry is still growing, and there are fewer providers competing for business. The quality of audits is comparable. The reports follow the same international formats and standards. You are just paying a premium for a less competitive market.
Most audit companies do not require you to be present. You book remotely, the auditor visits the factory, and you receive the report electronically. Travel costs to the factory (if outside a major city) are typically included in the day rate, though some companies charge extra for remote locations.
Vietnam-Specific Considerations
Factory auditing in Vietnam follows the same general principles as auditing anywhere in Asia, but there are a few things worth knowing about the local context.
Factory locations are spread out. Unlike China, where massive industrial clusters concentrate thousands of factories in tight zones, Vietnamese factories tend to be more dispersed. The major manufacturing provinces (Binh Duong, Dong Nai, Long An, Binh Phuoc in the south; Bac Ninh, Hai Phong, Thanh Hoa in the north) each have their own industrial parks, but distances between them can add up. This does not usually affect audit scheduling, but it is worth noting if you plan to audit multiple factories in a single trip.
Language barriers are real. Most factory owners and managers in Vietnam speak limited English, especially outside Ho Chi Minh City and Hanoi. Your auditor should be a Vietnamese native speaker. If you visit in person, bring a translator or work with a sourcing partner who can interpret.
Trading companies are common. One of the most frequent findings in Vietnamese factory audits is that the "manufacturer" is actually a trading company that outsources production. This is not always a dealbreaker, but you need to know about it before you place an order. A proper audit will identify this immediately by verifying the business license type and physically inspecting the production facility.
Relationship dynamics matter. Vietnamese business culture places significant weight on relationships and trust. A factory that welcomes an audit and cooperates openly is generally a good sign. A factory that resists, delays, or tries to limit what the auditor can see is a serious warning. How a supplier responds to the audit process tells you a lot about how they will handle production issues later. For more on how to negotiate with Vietnamese suppliers, see our dedicated guide.
How to Read an Audit Report
Third-party audit reports typically include a summary score (often on a scale like "Approved," "Approved with Conditions," "Not Approved"), followed by detailed findings organized by category (facility, quality systems, capacity, compliance, etc.).
Focus on these areas when reviewing:
Critical findings are issues that should stop you from placing an order until they are resolved. Examples: the factory does not actually produce your product type, the business license is invalid or expired, serious safety hazards, or evidence of child labor.
Major findings are significant issues that need attention but may not be dealbreakers if the factory is willing to address them. Examples: quality management system gaps, equipment maintenance issues, incomplete documentation.
Minor findings are areas for improvement that are common in developing-market factories and are generally acceptable for a first order. Examples: some missing calibration records, incomplete training logs, minor housekeeping issues.
No factory in Vietnam (or anywhere) will receive a perfect audit score. The goal is not perfection. It is to confirm that the factory is legitimate, capable, and operating at an acceptable standard for your product and order size. Use the audit to set a baseline, then follow up on major findings before production begins.
Common Mistakes Buyers Make with Factory Audits
Skipping the audit to save $300. This is the most expensive mistake in Vietnam sourcing. A $300 audit can prevent a $10,000+ loss from a fraudulent or incapable supplier. We have seen buyers lose entire orders because they took a factory's word over a phone call instead of spending a day's audit fee.
Auditing too late. The audit should happen before you finalize payment terms and certainly before you send a deposit. An audit after you have already committed capital defeats the purpose.
Using the wrong audit type. If you just need to confirm the factory is real and capable, a $300 SQA is sufficient. You do not need a $1,000 social compliance audit unless your buyer requires one. Match the audit scope to your actual risk.
Confusing audits with inspections. An audit tells you whether you should work with a factory. Inspections tell you whether a specific production run meets your standards. You need both, but they serve different purposes at different stages. Once your factory passes the audit and you place the order, shift to the inspection framework in our quality control in Vietnam guide to manage the production itself.
Only auditing once. A single audit captures a snapshot. If you are building a long-term supplier relationship, periodic re-audits (annually or when scaling volume) help you catch problems before they affect your orders.
Ignoring subcontracting findings. If the audit reveals that the factory outsources some production steps, that is not automatically a problem, but you need to understand which steps, to whom, and whether those subcontractors meet your standards. Some factories in Vietnam outsource specialized processes (printing, embroidery, plating) to partner workshops. Just make sure you know where your product is actually being made.
Factory Audits: Vietnam vs. China
If you are moving production from China to Vietnam, the audit process is essentially the same. The report formats, scoring systems, and audit standards are internationally consistent. The practical differences are:
Vietnam has fewer third-party audit companies, so pricing is higher (roughly 20% to 40% more than China for equivalent audits).
Vietnamese factories tend to be smaller on average, which can make audits faster but also means capacity constraints are more common.
The audit company landscape in Vietnam is growing quickly. Several major providers (V-Trust, QIMA, Bureau Veritas, Testcoo, Pro QC) now have significant Vietnamese operations with locally based auditors.
Communication with the factory during and after the audit may require Vietnamese-language support, whereas many Chinese factories have English-speaking staff.
The bottom line: do not skip the audit just because you already had a process in China. Vietnamese suppliers deserve the same verification, and the risks of not auditing are the same regardless of the country.
Get Your Factory Audited Before You Commit
Cosmo Sourcing has been helping buyers vet Vietnamese factories since 2014. We do not just send you a factory name and wish you luck. As part of our sourcing process, we verify suppliers on the ground, arrange factory audits through trusted third-party providers, and give you an honest assessment of whether a factory can actually deliver. Our flat-fee model means we have no financial incentive to push you toward any particular supplier. We typically collect original quotes from two to six factories so you can compare on capability, price, and audit findings before making a decision.
