Quality Inspection Report: Comparative Analysis of Flooring Products Manufactured in Vietnam and China
Introduction
Our QC team conducts rigorous inspections on over 300 containers of various flooring types annually, providing deep insights into the production processes, material differences, quality standards, and common defects in Vietnamese and Chinese flooring products. This report compares the manufacturing processes, raw materials, quality issues, and laboratory test results for different flooring types (e.g., laminate, engineered wood, SPC/WPC vinyl, and solid hardwood) produced in Vietnam and China. Additionally, we evaluate their suitability for export markets such as the USA, Canada, and Australia.
1. Production Processes and Manufacturing Differences
Vietnam:
Vietnamese flooring manufacturers emphasize manual craftsmanship, particularly for engineered wood and solid hardwood. The production process includes careful selection of local rubberwood and acacia, which are kiln-dried to stabilize moisture content. Laminate and SPC flooring production in Vietnam relies on imported German and Belgian wear layers, ensuring high abrasion resistance. However, inconsistencies in adhesive application and pressing techniques sometimes lead to delamination issues.
China:
Chinese factories utilize highly automated production lines, especially for laminate and rigid core (SPC/WPC) flooring. Local sourcing of HDF cores and limestone-based SPC materials reduces costs but may compromise dimensional stability in high-humidity environments. Chinese engineered wood often uses fast-growing eucalyptus or poplar cores with thin veneers, which are prone to warping if not properly treated.
2. Raw Material Differences
- Wood Flooring: Vietnamese factories use sustainable rubberwood and acacia, while Chinese producers favor eucalyptus and poplar for cost efficiency. Vietnamese hardwood tends to have tighter grain structures, enhancing durability.
- Laminate Flooring: Both countries import high-pressure laminate (HPL) surfaces, but Chinese laminates often use lower-density fiberboard to cut costs, affecting impact resistance.
- SPC/WPC Flooring: Vietnamese manufacturers prioritize imported PVC stabilizers, whereas Chinese SPC relies on local calcium carbonate fillers, which may reduce flexibility in cold climates.
3. Common Quality Defects
- Vietnam: Minor surface scratches (due to manual handling), uneven staining in hardwood, and occasional adhesive bleeding in engineered floors.
- China: More prevalent issues include edge chipping (laminate), core separation (engineered wood), and thermal expansion in SPC flooring due to filler-heavy compositions.
4. Laboratory Testing & Performance Data
Key tests conducted include:
- Abrasion Resistance (EN 13329): Vietnamese laminate averages 6,000–8,000 RPM, while Chinese products range 4,500–7,000 RPM.
- Moisture Content (ASTM D4442): Vietnamese hardwood maintains 6–8%, outperforming Chinese samples (8–10%).
- Formaldehyde Emissions (CARB Phase 2): Both countries comply, but Vietnamese factories show stricter adherence (≤0.05 ppm vs. China’s ≤0.07 ppm).
5. Export Market Suitability
- USA/Canada: Vietnamese hardwood and engineered floors are ideal for high-end residential use due to superior moisture stability. Chinese SPC is cost-effective for commercial projects but may require thicker wear layers for heavy traffic.
- Australia: Strict emissions standards favor Vietnamese laminate and low-VOC Chinese WPC. Climate adaptability tests show Vietnamese products perform better in tropical regions.
Conclusion
Vietnamese flooring excels in craftsmanship and material quality, making it suitable for premium markets, while Chinese products dominate budget-conscious segments with scalable production. Buyers should prioritize Vietnamese hardwood for durability and Chinese rigid core flooring for large-scale projects, provided thorough QC checks are implemented.
Recommendations for Importers:
- For US/Canadian buyers: Specify higher-density cores for Chinese laminate to avoid wear issues.
- For Australian buyers: Focus on formaldehyde compliance and moisture-resistant treatments.
