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
