Products classified under Tariff item 8459.70.90
Adjustable Pitch Threading Lathe Alternative
The Adjustable Pitch Threading Lathe Alternative is a compact universal threading machine with quick-change dies for creating metric and NPT threads on metal rods. It operates by removing material to form threads and is not a true lathe, so it falls under this tariff item for other threading machines. This low-cost model is popular for DIY and light industrial applications.
Benchtop CNC Threading Machine
The Benchtop CNC Threading Machine is a compact, computer-controlled machine tool designed for precision threading and tapping operations on metal parts. It removes material to create threads and is classified here as an other threading or tapping machine. This machine is suitable for small-scale production and prototyping.
Desktop Thread Milling Center
The Desktop Thread Milling Center is a small-footprint machine that combines tapping with limited milling to create custom threads in metal prototypes. It removes material to form threads and is classified here as an other threading machine. This equipment is intended for rapid prototyping laboratories and small-batch production.
Electric Tapper for Small Parts
The Electric Tapper for Small Parts is a handheld electric tapping tool with digital depth control for creating M1-M10 threads in thin metal sheets. It removes material to form internal threads and is classified here as an other tapping machine. This tool is used in electronics assembly and light metalworking.
Geared Pipe Threader
The Geared Pipe Threader is a floor-model threading machine for creating pressure-tight threads on steel pipes from 1/4 to 2 inches in diameter. It cuts threads by removing material and is classified here as an other threading machine. This equipment is essential for HVAC and fire sprinkler installations.
Grob G350 Threading Module
The Grob G350 is a 5-axis machining center with a dedicated threading pallet system for batch production of planetary gears. It creates precise helical threads through controlled metal removal. This machine is not numerically controlled, so it falls under tariff item 8459.70.90 as an other threading or tapping machine.
Manual Tapping Head Station
The Manual Tapping Head Station is a standalone manual tapping station with adjustable speed gearing for creating internal threads in metal workpieces. It removes material through chip formation and is classified here as an other tapping machine. This station is used in workshops for low-volume tapping operations.
Mitsubishi MV Series Thread Cutter
The Mitsubishi MV Series Thread Cutter is a wire electrical discharge machine (EDM) configured to cut thread forms in hardened tool steels. Although it uses electrical discharge rather than mechanical cutting, it is classified here as a machine tool for removing metal to create threads, consistent with the tariff item's scope for threading machines. It is designed for precision threading of mold components and other hardened parts.
Multi-Size Thread Chaser
The Multi-Size Thread Chaser is a precision thread chasing machine that repairs damaged threads on metal fasteners by selectively removing material. It is classified here as an other threading machine because it performs threading operations through metal removal. This machine is used in aircraft maintenance and precision repair applications.
Pneumatic Tapping Arm
The Pneumatic Tapping Arm is an articulated pneumatic tapping arm with auto-reversal for overhead and deep-hole tapping in metal castings. It removes material to create threads and is classified here as an other tapping machine. This arm is used in foundry and machining applications for improved ergonomics and productivity.
Portable Bolt Threading Machine
The Portable Bolt Threading Machine is a lightweight, portable die-head threading machine for creating external threads on pipes and bolts up to 2 inches in diameter. It removes material to form threads and is classified here as an other threading machine. This machine is commonly used in plumbing and construction applications.
Semi-Automatic Nut Tapping Machine
The Semi-Automatic Nut Tapping Machine is a bench-mounted semi-automatic machine for high-volume tapping of blind and through holes in metal nuts and fittings. It removes material to create threads and is classified here as an other tapping machine. This machine is used by fastener manufacturers for efficient production.
Used Accutex Tapping Module
The Used Accutex Tapping Module is a used EDM machine equipped with a tapping module for creating threads in metal parts after initial machining. It performs threading by removing metal through electrical discharge, and is classified here as a threading machine under the tariff item. This unit is intended for secondary threading operations in metalworking.
