HS Code for Building blocks

Building blocks made of cement, concrete, or artificial stone are classified under HS code 6810.11. This classification falls under Chapter 68, which covers articles of stone, plaster, cement, asbestos, mica, or similar materials. Heading 6810 specifically encompasses articles of cement, concrete, or artificial stone, whether or not they are reinforced with metal or other materials. The subheading 6810.11 is specifically reserved for building blocks and bricks. These items are characterized by their use in the construction of walls, foundations, and other structural elements. The classification is determined by the material composition—primarily a binder like Portland cement mixed with aggregates—and the fact that they are manufactured or molded products rather than natural stone. Even if the blocks contain steel reinforcement (rebar), they remain under this code because the concrete provides the essential character of the building component.

Products Included

Common Misclassification

Building blocks are often confused with ceramic bricks, which are classified under HS code 6904.10. The distinction lies in the material: 6810.11 is for cement/concrete, while 6904.10 is for fired clay. Another common error is classifying them under 6802 if they look like natural stone; however, if they are made from stone dust and a binder (artificial stone), they must stay in 6810. Toy building blocks are classified under 9503.00.
