9. Inspection Summary & Conclusion
Sampling Strategy: Random sampling was conducted per international quality inspection standards, with 10% of panels inspected per container (minimum 10 pieces per container) for dimensional, appearance, and functional tests; destructive and laboratory tests were performed on 1 sample per container.
Pass/Fail Criteria: All items must meet the specified U.S. import standards and customer requirements; failure of critical items (formaldehyde emission, structural strength, dimensional accuracy) results in overall inspection failure; minor defects (e.g., negligible surface blemishes) are acceptable if within agreed tolerance and do not affect performance or safety.
