A precision wax pattern used in the lost-wax investment casting process to create intricate turbine blade shapes for aerospace engines. It is classified under HTS 8480.30.00.00 as a molding pattern because it serves as the expendable template that forms the mold cavity when invested in ceramic slurry and melted out.

Import Tips
• Verify the pattern is specifically for molding and not a finished part; provide engineering drawings showing mold-forming intent to avoid reclassification as a metal component
• Include certificates of material composition (e.g
• wax type) and foundry process documentation to confirm use in metal casting
