Boiler Draft Fan Impeller from Japan
Precision-balanced rotor blades for forced draft or induced draft fans supporting combustion air/flue gas movement in boiler auxiliary systems. While fan assemblies may classify elsewhere, impellers as replacement parts fall under HTS 8404.90.00.00. Critical for airflow optimization.

Import Tips
• Dynamic balance certificates mandatory; imbalance causes operational failures
• Blade material (e.g
• abrasion-resistant alloys) affects tariff treatment
• Complete fan assemblies classify differently; declare as 'impeller only'
