Products classified under HTS 8480.30.00.00
Precision Mold Base Pattern Set
Matched cavity and core patterns for building injection mold bases in plastics manufacturing. HTS 8480.30.00.00 as molding patterns distinct from complete mold bases.
Investment Casting Wax Pattern for Turbine Blades
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.
Sand Casting Wooden Pattern for Engine Blocks
A durable wooden pattern with cope and drag sections used to create sand molds for large automotive engine blocks. Classified in HTS 8480.30.00.00 as it functions as the reusable molding pattern that shapes the sand into the negative form for molten metal pouring.
Die Casting Aluminum Pattern for Automotive Wheels
A machined aluminum pattern used to create the master die for high-pressure die casting of alloy wheels. It falls under HTS 8480.30.00.00 as a molding pattern since it is the prototype tool that defines the cavity shape for repeated metal injection molding.
Plastic Injection Molding Pattern Prototype
A 3D-printed or CNC-machined plastic pattern used for validating mold designs before steel tool production. HTS 8480.30.00.00 applies as it is a molding pattern for creating molds used in plastics manufacturing.
Glass Bottle Blow Molding Pattern
A graphite or cast iron pattern used to form the plaster mold for blow-and-blow glass bottle production. Classified under HTS 8480.30.00.00 for molding patterns used in mineral material (glass) molding processes.
Silicone Rubber Compression Molding Pattern
A metal or epoxy pattern for creating compression molds used in silicone rubber gasket production. It qualifies under HTS 8480.30.00.00 as a molding pattern specifically for rubber molding applications.
Semiconductor Wafer Crystal Grinder Pattern
A precision molding pattern used to calibrate crystal grinders for semiconductor boule diameter control per statistical notes. HTS 8480.30.00.00 covers it as a pattern for semiconductor manufacturing equipment.
Float Zone Crystal Puller Molding Pattern
Pattern for shaping the float zone furnace components used in monocrystalline silicon boule pulling, as noted in statistical notes (a)(i). Classified HTS 8480.30.00.00 for semiconductor crystal grower patterns.
Wafer Slicing Saw Calibration Pattern
Diamond-patterned test piece for calibrating wafer slicing saws from semiconductor boules, per statistical note (a)(ii)(B). Falls under HTS 8480.30.00.00 as specialized molding pattern for semiconductor equipment.
