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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If reinforced with steel fibers or mesh
Reinforced concrete blocks shift to 6810.19 due to added structural reinforcement, changing the tariff heading.
If primarily composed of ceramic materials
Blocks made mainly from fired clay or ceramics fall under Chapter 69 for ceramic building bricks, not artificial stone.
If sold as part of a complete prefabricated building kit
If integrated into Chapter 94 prefabricated structures, they may classify under 6810.91 for articles of cement used in buildings.
