Products classified under HTS 8474.31.00.00
Portable Electric Concrete Mixer
A compact, wheel-mounted electric-powered mixer designed specifically for blending cement, sand, and aggregates into concrete on construction sites. It falls under HTS 8474.31.00.00 as it is dedicated machinery for mixing concrete, a solid mineral substance in powder or paste form, essential for small-scale building projects.
Truck-Mounted Concrete Mixer Drum
A large rotating drum assembly mounted on transit mixer trucks for continuous mixing and transport of ready-mix concrete. Classified under HTS 8474.31.00.00 as it constitutes the core mixing machinery for concrete production during transit from batch plants to job sites.
Stationary Planetary Concrete Mixer
Industrial fixed-position mixer with planetary agitators for high-volume, homogeneous concrete batching in precast plants. It qualifies for HTS 8474.31.00.00 due to its specialized design for kneading concrete mixes from powder and aggregate components.
Twin-Shaft Concrete Mixer
High-intensity mixer with counter-rotating shafts for rapid, compulsory concrete mixing in ready-mix plants. Falls under HTS 8474.31.00.00 as specialized equipment for intensive kneading of concrete aggregates and cement paste.
Gasoline-Powered Mortar Mixer
Portable mixer with gasoline engine optimized for small batches of mortar used in masonry and tile setting. Classified in HTS 8474.31.00.00 as it specifically mixes mortar, explicitly covered under the concrete or mortar mixers heading.
Reversible Drum Concrete Mixer
Drum mixer that reverses rotation direction to discharge concrete without tilting, ideal for confined construction spaces. It belongs to HTS 8474.31.00.00 as dedicated concrete mixing machinery with specialized reversible discharge mechanism.
Continuous Concrete Mixer
High-capacity pugmill-style mixer for non-stop concrete production feeding slipform pavers and pumps. Covered by HTS 8474.31.00.00 for its continuous mixing of concrete from solid mineral inputs.
Mini Concrete Mixer for DIY Use
Lightweight, hand-push electric mixer for homeowner concrete projects like patios and footings. Still falls under HTS 8474.31.00.00 despite small size, as it performs the specific function of concrete mixing.
