Import Tips
• Conduct density testing to confirm MDF specs; densities outside 450-800 kg/m³ may reclassify to particleboard (4410)
• Prepare invoices specifying 'building construction dedicated' with edge details to preempt CBP queries
• Avoid common error of importing in furniture sets, which could invoke GRI 3(b) for composite goods classification
