HS Code for Concrete blocks

Concrete blocks are classified under HS code 6810.11, which falls within Chapter 68: Articles of stone, plaster, cement, asbestos, mica or similar materials. This specific subheading is designated for building blocks and bricks made of cement, concrete, or artificial stone, whether or not they are reinforced with metal or other materials. The classification is determined by the primary material—concrete—and the intended use as a discrete unit for masonry construction. These items are manufactured by molding a mixture of cement, aggregates (such as sand, gravel, or crushed stone), and water. The resulting product is a building unit used to construct walls, partitions, and other structures. The code 6810.11 specifically excludes prefabricated structural components for building or civil engineering, which are classified under 6810.91. It also excludes ceramic bricks, which are found in Chapter 69. The distinction between a block and a prefabricated component is often based on size and the degree of engineering; blocks are generally standard sizes used by masons, whereas components are often custom-engineered for specific structural roles. This classification ensures that basic building materials are separated from complex structural elements.

Common Misclassification

Concrete blocks are often misclassified under 6810.91, which is reserved for prefabricated structural components like beams or wall panels. They may also be confused with 6904.10, which covers ceramic building bricks. It is vital to distinguish the material (cement vs. clay) and the function (standard block vs. engineered component) to avoid using the incorrect code. Paving stones may also be confused with 6801.00 if they are made of natural stone rather than concrete.
