Subheadings
Products classified under HTS 8430.49.80
Soil Sampling Auger Rig
Truck-mounted hydraulic auger for collecting undisturbed soil samples in environmental site assessments. HTS 8430.49.80 classification for specialized earth boring sampling equipment.
Auger Boring Machine
Rotary drilling rig using continuous flight augers to bore horizontal holes through soil for pipe jacking in sewer construction. Classified in HTS 8430.49.80 as other earth boring machinery distinct from vertical pile drivers.
Core Drill Rig
Portable diamond core drilling machine for extracting cylindrical earth/rock samples in geotechnical investigations. Falls under HTS 8430.49.80 as other boring machinery specialized for sampling rather than production excavation.
Geothermal Drilling Rig
Compact rotary rig for boring vertical ground source heat exchanger holes up to 500ft deep. HTS 8430.49.80 applies to earth boring machinery for renewable energy heat pump installations.
Pile Hole Boring Machine
Crawler-mounted rotary table machine for large-diameter cast-in-place concrete pile holes. Classified under HTS 8430.49.80 as other boring machinery distinct from pile drivers/extractors.
Horizontal Directional Drill
A compact machine used for installing underground pipelines and cables by drilling a pilot hole horizontally beneath the surface without trenching. It falls under HTS 8430.49.80 as other boring machinery for earth designed for precise subsurface excavation in utility construction.
Tunnel Boring Machine Head
Rotary cutting head assembly for small-diameter tunnel excavation in soft ground urban projects. HTS 8430.49.80 covers this as other boring machinery for earth, excluding full TBMs often self-propelled.
Microtunneling Boring System
Remote-controlled pipe jacking machine for precise small-diameter tunnel boring under rivers/railways. HTS 8430.49.80 classification as other earth boring machinery for trenchless technology applications.
Rock Auger Earth Drill
Heavy-duty hydraulic auger attachment for drilling foundation holes in rocky soil conditions. Classified HTS 8430.49.80 as specialized earth boring equipment for construction site preparation.
Directional Boring Locator
Walkover guidance system with sonde transmitter for tracking underground boring head path. While primarily guidance, integral to classified boring systems under HTS 8430.49.80 statistical provisions.
