6810.11.00 - Building blocks and bricks

This HTS category encompasses pre-formed articles used in construction, specifically building blocks and bricks made from cement, concrete, or artificial stone. These items are designed for the structural assembly of walls, foundations, and other building elements. They are distinguished by their primary function as modular construction units and their composition, which relies on binders like cement and aggregates.

Within this subdivision, the distinction is made between specific types of building blocks and bricks and a general "other" category. This allows for more precise classification of articles based on their material composition or intended use, facilitating accurate tariff application.

The subcategories provided offer further granularity. For instance, 6810.11.00.10 specifically addresses articles with a high magnesia content and particular carbon and binding agent characteristics, likely for specialized refractory or industrial applications. The remaining 6810.11.00.70 subcategory covers all other building blocks and bricks within this broader classification that do not meet the specific criteria of the preceding subcategory.
