Inspection Location: WHITE BIRCH PLYWOOD Manufacturing Facility, Malaysia
Product Inspected: UV Prefinished Birch Plywood
Inspected On Behalf Of: A designated U.S.-based Importer
Purpose of Inspection: To verify and document that the production of UV Prefinished Birch Plywood meets the agreed-upon specifications and quality standards for finish durability and substrate integrity.
1.0 Executive Summary
This report details the findings of a comprehensive quality inspection conducted on August 28, 2025, at our manufacturing facility in Malaysia. The inspection was performed in the presence of a representative from our U.S.-based importer client. The scope covered the evaluation of both the birch plywood substrate and the UV-cured finishes for various thicknesses (5.2mm and 18mm) and finish types (UV 2 Sides, UV 1 Side).
The inspection concluded that the sampled products consistently conform to the stringent quality parameters agreed upon with the client. All tested aspects, including substrate quality, finish hardness, scratch resistance, and aesthetic consistency, were found to be satisfactory.
This report is published with the client’s consent, with all identifying business information redacted to maintain confidentiality.

3.0 Inspection Methodology & Acceptance Criteria
The inspection was conducted on randomly selected panels from finished production batches. The following standardized test methods were employed:
- Substrate Inspection: Visual examination for surface defects (e.g., voids, patches, overlaps) and measurement of thickness, squareness, and dimensional stability.
- Finish Hardness: Tested using a standardized pencil hardness test (ASTM D3363).
- Scratch Resistance: Assessed using a scratch test with a calibrated hardness pick.
- Adhesion: Cross-cut tape test (ASTM D3359) to evaluate the bonding between the UV coating and the plywood substrate.
- Color & Gloss Uniformity: Visual inspection under standard lighting conditions against approved master samples.
- Chemical Resistance: Spot testing with common agents to check for discoloration or finish degradation.
4.0 Detailed Findings
4.1 Birch Plywood Substrate Quality
- Result: PASS
- Observations: The birch plywood substrate for both 5.2mm and 18mm panels was found to be of high quality. Surfaces were smooth and even, providing an excellent base for the UV finishing process. No significant core gaps, voids, or surface imperfections were detected. Thickness measurements were within the specified tolerances.
4.2 UV Finish System Evaluation
The UV finish was evaluated based on its constituent layers and final properties.
- UV Base Coat:
- Function: To seal the wood substrate and provide a uniform surface for the topcoat.
- Result: PASS. The base coat was applied evenly, with complete absorption and sealing of the wood grain, ensuring a perfectly smooth foundation.
- UV Top Coat:
- Function: To provide the final durability, sheen, and protective properties.
- Result: PASS. The top coat was uniform and consistent across all panels, with the specified sheen level (e.g., UV Sheen) matching the approved standard.
- Number of UV Coats:
- Result: PASS. The application of the specified number of UV coats (Base Coat + Top Coat) was confirmed, resulting in a sufficient film build for enhanced durability.
4.3 Physical and Durability Tests
- Hardness (Pencil Hardness Test):
- Standard Required: ≥ 2H
- Result Achieved: 3H
- Observation: The UV finish demonstrated excellent hardness, exceeding the minimum requirement, indicating high resistance to surface marring.
- Scratch Resistance:
- Result: PASS
- Observation: Under moderate pressure, the finish showed high resistance to scratching. Only minor, superficial marks were observed under high-pressure testing, which is considered acceptable for the intended applications.
- Adhesion (Cross-Cut Tape Test):
- Standard Required: 5B (Best Rating – 0% removal)
- Result Achieved: 5B
- Observation: The adhesion of the UV coating to the birch plywood substrate is excellent, with no flaking or detachment observed.
- Color Fastness & Resistance to Discoloration:
- Result: PASS
- Observation: Panels subjected to limited exposure tests showed no noticeable yellowing or color change. The UV finish provides effective protection against discoloration from light exposure.
5.0 Conclusion
The quality inspection conducted on August 28, 2025, confirms that the batch of UV Prefinished Birch Plywood (5.2mm and 18mm) manufactured at our facility fully complies with the technical and quality specifications required by our U.S. importer client. The product exhibits superior substrate quality, a robust and well-applied UV finish system, and excels in critical performance areas such as hardness, scratch resistance, and finish adhesion.
This successful inspection underscores our commitment to manufacturing excellence and our capability to consistently deliver high-performance, durable products for the North American market.
