Products classified under HTS 8406.90.60.00
Cast-Iron Turbine Rotor Post-Fin Cleanup
Cast iron rotor for small industrial vapor turbines, post-casting cleanup removing all fins/sprues for machining setup. Semi-finished per statistical notes. 8406.90.60.00 classification maintained.
Inconel Alloy Rotor for High-Temp Steam Service
Inconel superalloy rotor cleaned/machined for ultra-high temperature steam turbines, fins removed only. For supercritical power plants. HTS 8406.90.60.00 as limited advancement vapor turbine part.
Monel Rotor Blank for Corrosive Vapor Environment
Monel alloy rotor blank for corrosive industrial vapor turbines, sprues/gates machined off for fixturing. Semi-finished 8406.90.60.00 status.
Stellite-Coated Rotor Pre-Finishing Stage
Rotor with Stellite erosion coating, fins removed for finishing location only. For steam turbine last stage blades support. 8406.90.60.00 semi-finished.
Titanium Rotor for Lightweight Turbine Design
Lightweight titanium rotor cleaned/machined for aerospace-derived industrial turbines. Fins/gates removed only. HTS 8406.90.60.00 vapor turbine part.
Large Forged Rotor Post-Riser Removal
8-meter class forged rotor for utility steam turbines, risers machined off for horizontal boring mill setup. Semi-finished per 8406.90.60.00.
Niobium-Stabilized Rotor for Sour Service
Nb-stabilized stainless rotor for H2S-containing steam, cleaned/machined casting removal only. 8406.90.60.00 classification.
Bi-Rotor Set Cleaned for Finishing
Matched pair of high/low pressure rotors, both cleaned/machined for location only, imported as set. Each qualifies individually under 8406.90.60.00.
Machined Steam Turbine Rotor for Industrial Power Generation
A precision-machined rotor designed for steam turbines used in industrial power plants, cleaned and machined solely to remove casting fins, gates, sprues, and risers. This allows precise location in finishing machinery without further advancement. It falls under HTS 8406.90.60.00 as a semi-finished part of steam turbines limited to basic post-casting cleanup.
Cleaned Vapor Turbine Rotor for Cogeneration Plants
A rotor for organic vapor turbines in cogeneration facilities, processed only by cleaning and minimal machining to eliminate sprues, risers, and fins from casting. This semi-finished state permits accurate fixturing for subsequent finishing operations. Classified in 8406.90.60.00 due to restriction to basic preparation without blade attachment or balancing.
Fin-Removed Rotor for Utility Steam Turbines
Large-scale rotor for utility-scale steam turbines, machined exclusively to remove casting fins, gates, sprues, and risers for proper fixturing in CNC finishing equipment. No balancing grooves or blade roots added. Meets HTS 8406.90.60.00 as not further advanced than basic casting cleanup for steam/other vapor turbine parts.
Sprue-Cleaned Rotor for Marine Vapor Turbines
Corrosion-resistant rotor for marine vapor turbine propulsion systems, cleaned of sprues/risers and lightly machined for location only. Prevents misfixturing in final blade milling operations. HTS 8406.90.60.00 applies as vapor turbine part not exceeding casting cleanup stage.
Gate-Machined Rotor Blank for Geothermal Turbines
High-temperature rotor blank for geothermal steam turbines, with gates and risers machined off to enable precise finishing setup. No functional features like keyways added. Fits 8406.90.60.00 limitation for steam turbine rotors at cleaned/machined casting removal stage.
Riser-Removed Low-Pressure Steam Turbine Rotor
Low-pressure stage rotor for combined cycle steam turbines, risers removed and surface cleaned/machined for finishing fixture location. Remains semi-finished per HTS 8406.90.60.00 criteria for vapor turbine parts.
Precision-Location Machined HP Turbine Rotor
High-pressure steam turbine rotor machined only at bearing journals for precise finishing machine location, fins/gates fully removed. No blade attachment features. HTS 8406.90.60.00 for steam turbine rotors not further advanced.
