Products classified under HTS 6810.11.00.70
Sound-Absorbing Concrete Blocks
Concrete blocks engineered with internal textures or materials to reduce noise in urban barriers or studios. HTS 6810.11.00.70 applies as unreinforced building blocks of artificial stone for construction. Acoustic properties don't change core classification.
Thermal Mass Concrete Blocks
Dense concrete blocks designed to store and release heat for passive solar buildings. Classified HTS 6810.11.00.70 as unreinforced artificial stone building blocks. High thermal capacity from specific aggregates.
Concrete Garden Border Blocks
Small scalloped or rectangular concrete blocks for defining garden beds and paths. HTS 6810.11.00.70 for other concrete building/landscaping blocks, unreinforced.
Concrete Foundation Blocks
Precast blocks for pier-and-beam foundations, providing level bases. HTS 6810.11.00.70 as unreinforced concrete building blocks.
Concrete Screen Blocks
Lattice-pattern concrete blocks for privacy screens and facades. HTS 6810.11.00.70 other blocks.
Concrete Utility Blocks
Versatile blocks for cable trenches or meter bases. HTS 6810.11.00.70.
Concrete Lintel Blocks
U-shaped blocks for door/window headers. HTS 6810.11.00.70.
Concrete Corner Blocks
Angled blocks for clean wall corners. HTS 6810.11.00.70.
Concrete Interlocking Paver Blocks
These are precast concrete blocks designed with interlocking shapes for use in patios, walkways, and driveways. They fall under HTS 6810.11.00.70 as building blocks of concrete, not reinforced, used in construction for paving surfaces. The 'other' subheading applies since they are neither standard bricks nor specified tiles.
Lightweight Concrete Breeze Blocks
Breeze blocks are lightweight concrete building blocks with voids for ventilation and reduced weight, commonly used in non-load-bearing walls. Classified under HTS 6810.11.00.70 as unreinforced concrete building blocks, distinct from solid bricks. They qualify as 'other' blocks for construction purposes.
Concrete Curbing Blocks
Precast concrete blocks shaped for edging lawns, driveways, and paths, providing a stable border. HTS 6810.11.00.70 covers these as unreinforced concrete building blocks used in landscaping construction. They are 'other' since not bricks or flagstones.
Perforated Concrete Partition Blocks
These concrete blocks feature holes for wiring or piping, ideal for interior partition walls in commercial buildings. Under HTS 6810.11.00.70 as other unreinforced concrete building blocks for construction. Perforations aid installation without altering classification.
Concrete Half-Blocks for Walls
Half-height concrete blocks used for constructing shorter walls, retaining edges, or bonding full courses. Classified in HTS 6810.11.00.70 as other concrete building blocks, unreinforced, for masonry applications.
Concrete Retaining Wall Blocks
Segmental concrete blocks stacked without mortar for gravity retaining walls up to certain heights. Under HTS 6810.11.00.70 as other unreinforced concrete building blocks for civil engineering. Designed for soil retention in landscaping.
