Melamine-Impregnated Tongue-and-Groove MDF Siding from China
Melamine-impregnated MDF siding boards, under 5 mm thick, with continuous rabbetted edges and a synthetic resin lamination for weather-resistant building exteriors. The melamine treatment provides a moisture barrier, while the tongue-and-groove profiling allows for interlocking installation. These boards are classified under tariff item 4411.12.00 as MDF of a thickness not exceeding 5 mm, with the resin lamination considered a surface treatment that does not change their fibreboard character.

Import Tips
• Verify that the melamine lamination is not applied in a way that gives the boards the character of laminated wood panels, which could shift classification
• Provide technical data sheets showing the MDF core and resin content to CBSA upon request
• Confirm the boards are not surface-covered with decorative laminates, as that may fall under other headings
