12mm Thick MDF Sheet from Canada

Medium density fiberboard (MDF) panel measuring 6 feet by 4 feet with thickness of 12mm, made from wood fibers bonded with resins. Classified under HTS 4411.13.90.90 as MDF exceeding 5mm but not exceeding 9mm is a misnomer; this thick variant falls in 'Other' due to specific thickness criteria in the hierarchy, but actually exceeds 9mm so properly 4411.13 but detailed as other. Used for furniture and cabinetry construction.

Import Tips

Verify exact thickness measurement as classifications split at 5mm and 9mm thresholds; provide caliper certifications

Include mill test reports confirming density between 0.45-0.80 g/cm³ and resin content for Customs verification

Avoid misclassification as particleboard (4411.11) by demonstrating uniform fiber structure via samples
