Choose the core by component
Cabinet sides, shelves, backs and doors do different jobs. A stable painted door core may not be the same material as the cabinet box, and a lightweight back panel is not a substitute for the specified structural side. Ask for each part to be named in the schedule.
| Core | Useful characteristics | What to resolve |
|---|---|---|
| Plywood | Cross-layer construction; a useful option where screw fixing and exposed edges matter. | Core quality, face grade, adhesive system, thickness and moisture exposure. |
| Particleboard | A flat panel used beneath decorative surfaces. | Declared panel grade, shelf span, fastening and edge protection. |
| MDF | A smooth, uniform core suited to painted or routed components. | Thickness, finish build-up, fixing details and protection from water. |
| Solid wood / veneer | Grain and tactile character. Veneer is a face over a substrate. | Species, cut, grain direction, movement allowances and backing construction. |
Read moisture resistance precisely
“Moisture-resistant” does not mean that an installed cabinet can tolerate a continuing leak. The board grade is one part of the assembly. Exposed cut-outs, sink edges, site fixings and joints must be detailed for their actual conditions.
For a sink base or vanity, identify the wet-risk zones and how they will be sealed. Include access to the plumbing so a small leak can be found and repaired. In a wardrobe, pay equal attention to wall dampness and ventilation rather than assuming a premium board solves the room conditions.
Match documentation to the destination
| Market / label | What to request | Avoid this shortcut |
|---|---|---|
| United States / TSCA Title VI | Documentation and traceability for the regulated composite-wood product, with the applicable certification and labeling. | Treating a Chinese grade label as a US certificate. |
| European Union | A review of the current REACH formaldehyde restriction and applicable test conditions for the finished article. | Assuming an E1 panel declaration alone settles the finished product’s requirements. |
| China / GB standards | The dated report, product identity, applicable mandatory standard and any declared voluntary grade. | Reading E0 or ENF without a test method or named product. |
| UK and other destinations | The requirements applicable to the specific jurisdiction and project. | Assuming an EU statement automatically covers every destination. |
EU Regulation 2023/1464 applies its formaldehyde restriction to relevant articles after August 6, 2026. China’s GB 18580-2025 took effect on June 1, 2026. Older comparison tables need to be read against these changes.
Check the report, not just the badge
- Product name, panel supplier and manufacturing site match the proposed material.
- The standard, version, test method and unit are stated.
- The report covers the relevant material, thickness or product family.
- The certifier or laboratory and report date are identifiable.
- The delivery documentation can be traced to the proposed product.
A report for a board is not automatically a report for every coating, adhesive or finished cabinet made with it. Ask which part of the specification each document supports.
Put the complete assembly in writing
Record the core and thickness for each component, the decorative face on both sides, the edge-banding material and the treatment of concealed cuts. Agree which faces need matching grain or color and which are service surfaces.
Use the cabinet substrates library for component references and the emission ratings article for a closer explanation of the market labels. Availability and project documentation should be confirmed for the proposed material before approval.
