Supplier Due Diligence & Procurement Auditing

Independent Supplier Due Diligence in China

Choosing the right supplier in China is one of the most important commercial decisions an importer will make. The difference between a capable manufacturer and the wrong manufacturer rarely becomes obvious during the quotation stage. It becomes apparent months later through quality failures, project delays, compliance issues, unexpected costs, warranty claims, or damaged customer relationships.

At Dracon International, supplier due diligence is the foundation of every procurement programme.

​

For more than 15 years, we have operated on the ground in China, independently qualifying manufacturers for clients across New Zealand, Australia, the Pacific Islands and increasingly the Middle East. Our role is not to represent factories or act as a trading company. We work exclusively for our clients, providing objective supplier assessments, procurement intelligence and ongoing project oversight throughout the sourcing and manufacturing lifecycle.

Our objective is simple:

​

Reduce procurement risk. Improve supplier performance. Build long-term supply chains that continue delivering value for years, not just one shipment.

Procurement Begins Long Before the First Quote

One of the biggest misconceptions about buying from China is that procurement starts once quotations are received.

​

In reality, procurement begins much earlier.

Before pricing can even be compared, suppliers must first be qualified.

Every year we review manufacturers with impressive websites, professional sales teams and attractive pricing that ultimately fail our assessment process. Some lack production capability. Others outsource critical components without disclosure. Many hold certificates that don't actually apply to the products being quoted, while others simply have no experience producing to New Zealand or Australian standards.

​

A low price has very little value if the supplier cannot consistently deliver.

Our due diligence process exists to remove those suppliers before they become expensive mistakes.

 

Our Supplier Due Diligence Framework

Every project is different, however our qualification framework generally follows the same structured methodology.

​

1. Project Discovery & Technical Review

Before approaching any manufacturer, we first seek to understand exactly what the client is trying to achieve.

This normally includes reviewing:

• Architectural drawings
• Engineering drawings
• Specifications
• Bill of Quantities (BOQ)
• Material schedules
• Performance requirements
• Compliance obligations
• Delivery programme
• Commercial objectives

Without accurate project documentation, suppliers cannot provide accurate quotations and meaningful comparisons become almost impossible.

We often prepare a structured Chinese-language tender package so every shortlisted manufacturer is pricing exactly the same scope of works.

This removes ambiguity and allows genuine "apples with apples" comparisons.

 

2. Manufacturer Identification

Unlike sourcing platforms that rely on advertising visibility, we identify manufacturers through years of industry relationships, direct market research and sector-specific networks developed over more than fifteen years.

Depending on the project we may review anywhere from five to more than thirty manufacturers before progressing to detailed assessment.

Selection criteria include:

• Manufacturing specialisation
• Years operating
• Export markets
• Production capability
• Project experience
• Factory scale
• Product suitability
• Industry reputation

The objective is quality, not quantity.

 

3. Business Verification

A legitimate business registration alone does not prove manufacturing capability.

We verify:

• Chinese business registration
• Legal operating status
• Shareholding structure
• Manufacturing licences
• Export registration
• Years trading
• Financial maturity
• Company history

Where appropriate we also investigate previous litigation, ownership changes and operational consistency.

 

4. Factory Capability Assessment

This stage determines whether a supplier can actually manufacture the products they claim.

Areas assessed include:

• Factory size
• Production lines
• Manufacturing equipment
• Automation levels
• CNC capability
• Welding systems
• Surface finishing
• Assembly processes
• Workforce capability
• Engineering support
• Production planning
• Monthly production capacity
• Scalability

We also assess whether critical production processes are performed in-house or subcontracted elsewhere.

This distinction often becomes critical for quality control and delivery certainty.

 

5. Quality Management Systems

Quality should never rely solely on final inspection.

We review how quality is managed throughout production.

Assessment includes:

• Incoming material inspections
• First article inspections
• In-process inspections
• Final inspections
• Hold point procedures
• Calibration systems
• Traceability
• Non-conformance reporting
• Corrective action procedures
• Internal testing capability
• Continuous improvement systems

Where appropriate we recommend additional third-party inspections through organisations such as SGS or V-Trust, particularly at critical production milestones before shipment approval.

 

6. Compliance Verification

This is one of the areas where we regularly identify the greatest risk.

Many manufacturers genuinely believe their products comply because they possess certificates.

Unfortunately certificates are often:

• Expired
• Issued for different products
• Issued under previous factory ownership
• Not recognised in New Zealand or Australia
• Laboratory reports rather than product certification
• Based on overseas standards only

We independently review:

• Product certifications
• Test reports
• Factory certifications
• Quality system certifications
• Declaration documents
• Technical data
• Material traceability
• Welding procedures
• Steel grades
• Fire testing
• Structural testing
• Environmental testing

Where possible documentation is cross-checked directly with issuing authorities.

For regulated products this stage is often the difference between successful market entry and expensive project delays.

 

7. Supply Chain Assessment

Strong factories also require strong suppliers.

We assess:

• Raw material sourcing
• Approved supplier systems
• Steel procurement
• Aluminium sourcing
• Hardware suppliers
• Glass suppliers
• Electrical components
• Plumbing components
• Supply continuity
• Inventory management
• Alternative sourcing capability

Recent global supply disruptions demonstrated that understanding second and third-tier suppliers is becoming increasingly important.

 

8. Commercial & Project Management Assessment

Good manufacturing capability means very little without effective project management.

We assess:

• English communication
• Technical understanding
• Responsiveness
• Drawing interpretation
• Documentation quality
• Reporting capability
• Commercial professionalism
• Engineering support
• Problem solving
• Client service

Many projects succeed or fail simply because communication breaks down.

 

9. Comparative Supplier Evaluation

Once due diligence is completed we compare suppliers across multiple weighted criteria rather than price alone.

Typical evaluation categories include:

• Capability
• Compliance
• Commercial competitiveness
• Quality systems
• Engineering support
• Production capacity
• Communication
• Delivery performance
• Supply chain stability
• Long-term partnership potential

This enables informed commercial decisions rather than selecting suppliers purely on price.

 

Procurement Partnership — Beyond Supplier Selection

Finding the right supplier is only the beginning.

Once manufacturing commences, procurement becomes an active management process.

Dracon continues supporting clients through:

• Commercial negotiations
• Purchase contract review
• Production scheduling
• Engineering coordination
• Technical clarification
• Material verification
• Manufacturing oversight
• Inspection hold points
• Third-party inspections
• Packing verification
• Container loading supervision
• Export documentation
• Freight coordination
• Delivery monitoring

We remain involved until products have been manufactured, inspected, packed and released for shipment.

 

Examples of Due Diligence in Practice

New Zealand Windows & Doors Programme

For a large residential programme, more than twenty Chinese window manufacturers were reviewed.

Many claimed compliance with AS/NZS 2047.

Following technical review, only a small number demonstrated genuine capability through independently verified testing, documented quality systems, engineering support and previous export history into regulated markets.

The result was a compliant supply chain capable of delivering significant savings while maintaining New Zealand performance requirements.

 

Aluminium Ringlock Scaffolding

Rather than purchasing from the first available supplier, multiple manufacturers were assessed across aluminium grades, welding procedures, extrusion quality, dimensional consistency and export capability.

The selected manufacturer supplied major international scaffold brands using the same production systems and quality controls, providing clients access to Tier One manufacturing without Tier One pricing.

 

Modular Housing

Modular housing is one of the most misunderstood sectors in China.

Many factories advertise premium modular homes online, however detailed audits often reveal significant differences in engineering capability, structural design, insulation systems, waterproofing, electrical standards and export experience.

Supplier qualification before procurement dramatically reduces project risk and establishes a far stronger foundation for successful delivery.

 

Why Long-Term Supply Chains Create Higher Returns

One-off sourcing rarely delivers the greatest value.

The greatest commercial advantage comes from building a supply chain that improves over time.

As relationships mature:

• supplier performance improves
• pricing becomes more competitive
• quality systems strengthen
• communication improves
• engineering knowledge accumulates
• production becomes more predictable
• lead times reduce
• commercial leverage increases

The result is not simply lower pricing.

The result is a procurement system that continues generating value year after year.

This is why Dracon has deliberately shifted away from one-off sourcing projects.

Today we focus on a smaller number of long-term procurement partnerships where we can continue refining and strengthening our clients' supply chains over multiple projects.

 

Why Clients Engage Dracon

Our clients don't engage us because they cannot buy from China.

They engage us because they recognise that successful procurement requires far more than obtaining quotations.

They want an experienced team on the ground that understands both Chinese manufacturing and Western commercial expectations.

For more than fifteen years we have helped businesses avoid costly mistakes, verify manufacturers, strengthen quality systems and establish procurement programmes that continue delivering commercial returns long after the first shipment arrives.

We don't represent factories.

We represent our clients.

That independence allows every recommendation we make to be based on evidence, capability and long-term commercial performance—not sales commissions or factory incentives.

Procurement is not the process of buying products.

Procurement is the disciplined process of building supply chains that consistently outperform the market.

That is where Dracon International delivers its greatest value.
