| Intended service environment | Dry interior use | The panel is designed for conditions where moisture exposure is limited and stable. | Furniture components, wall panels, partitions, packaging, and interior fit-out. | Confirm the applicable product standard, moisture limits, thickness tolerance, and storage requirements. |
| Bonding performance | EN 314-2 Class 1 | Bonding intended for dry conditions; it is not a guarantee of weather resistance. | Indoor applications with controlled humidity and no prolonged wetting. | Request test reports or declarations showing the bonding class and test method. |
| Bonding performance | EN 314-2 Class 2 | Bonding suitable for limited exposure to moisture, such as occasional damp conditions. | Kitchens, bathrooms with proper protection, interior construction, and sheltered applications. | Check whether the intended project requires a higher durability class or additional sealing. |
| Bonding performance | EN 314-2 Class 3 | Bonding suitable for exterior conditions and repeated wetting, subject to the full panel specification. | Exterior cladding substrates, outdoor construction, transport structures, and humid environments. | Verify the full durability specification, face veneer quality, edge sealing, and required coating system. |
| Use class under EN 636 | EN 636-1 | Plywood for dry conditions. | Interior building work and general dry-use fabrication. | Do not substitute it for a moisture-resistant or exterior grade without project approval. |
| Use class under EN 636 | EN 636-2 | Plywood for humid conditions. | Covered exterior areas and interior locations with elevated humidity. | Check exposure duration, edge protection, surface coating, and local building requirements. |
| Use class under EN 636 | EN 636-3 | Plywood for exterior conditions. | Outdoor applications where the panel is exposed to weather, when correctly designed and protected. | Confirm structural design, preservative treatment where needed, coating compatibility, and maintenance requirements. |
| Core material | Poplar core | Usually lightweight and easy to machine, with lower density than many hardwood alternatives. | Lightweight furniture, interior panels, doors, and applications where low panel weight is important. | Check density, screw-holding performance, veneer gaps, core joint quality, and moisture resistance. |
| Core material | Eucalyptus or other hardwood core | Generally denser and harder than lightweight species, with good durability potential when properly manufactured. | Construction panels, shelving, flooring substrates, transport components, and higher-wear applications. | Confirm density consistency, pressing quality, formaldehyde classification, and dimensional stability. |
| Core material | Birch or other fine-grained hardwood core | Typically dense, uniform, and suitable for machining and edge finishing. | Precision furniture, visible edges, machining-intensive components, and demanding interior fabrication. | Inspect edge voids, number of plies, thickness tolerance, and surface sanding quality. |
| Core material | Mixed hardwood or softwood core | Performance can vary widely according to species mix, veneer arrangement, density, and manufacturing control. | General-purpose panels where the specification and price balance are more important than a uniform exposed edge. | Request species information, average density, visual samples, and test data instead of relying only on the term “hardwood.” |
| Surface quality | A-grade or face-grade veneer | Cleaner appearance with fewer repaired defects, knots, open splits, and patches than lower visual grades. | Visible furniture surfaces, painted panels, decorative interiors, and clear-finished components. | Define allowable knots, patches, discoloration, sanding marks, and color variation in the purchase specification. |
| Surface quality | B-grade face | Good appearance with limited natural defects and generally more repairs than a premium face grade. | Painted furniture, interior joinery, wall panels, and surfaces that will receive finishing. | Inspect the actual sample because grade definitions differ by standard, species, and supplier specification. |
| Surface quality | C or utility face | More visible knots, open defects, patches, color variation, and local surface imperfections are permitted. | Structural or semi-concealed components, packaging, subfloor layers, and non-decorative construction work. | Confirm whether open defects require filling and whether the panel will be covered or directly exposed. |
| Surface combination | BB/CC or similar commercial notation | The first letter generally describes the better face and the second letter the back face; exact defect limits depend on the governing standard. | Projects requiring a presentable front face while the reverse side is concealed or less critical. | Always identify the grading standard and written defect limits; letter pairs are not globally interchangeable. |
| Panel construction | Balanced odd-numbered veneer lay-up | Cross-oriented veneer layers help improve dimensional stability and reduce directional movement. | General panels, furniture, cabinetry, partitions, and construction components. | Check veneer orientation, ply count, core alignment, face balance, and thickness uniformity. |
| Dimensional quality | Standard thickness and flatness control | Thickness variation, warping, twist, and edge squareness affect installation, machining, and joint accuracy. | All projects, especially CNC machining, modular construction, flooring, and laminated assemblies. | Measure samples with calibrated tools and agree on tolerances, panel size, flatness, and moisture content. |
| Health and compliance | Formaldehyde emission classification | Emission requirements vary by destination market and may be defined by standards such as E1 or other local regulations. | Interior projects, schools, offices, residential buildings, and enclosed transport spaces. | Request a valid test report for the destination country and confirm the test method and production date. |
