HS Code for Concrete structural components

Prefabricated structural components made of concrete are classified under HS code 6810.91. Chapter 68 covers articles of stone, plaster, cement, asbestos, mica, or similar materials. Heading 6810 specifically addresses articles of cement, concrete, or artificial stone, whether or not reinforced. The subheading 6810.91 is reserved for prefabricated structural components for building or civil engineering. This classification is applied because the products are finished articles that have been cast and cured in a factory environment before being transported to a construction site for assembly. The presence of steel reinforcement (rebar) or prestressing cables does not change this classification, as the essential character of the article is provided by the concrete.

Products Included

• Precast concrete bridge girders and beams
• Prefabricated concrete floor slabs and roof elements
• Precast concrete columns and pillars
• Concrete foundation piles
• Prefabricated wall panels for industrial buildings

Common Misclassification

These components are often confused with HS code 6810.11, which covers building blocks and bricks. While both are made of concrete, 6810.91 is specific to "structural" components used in engineering, whereas 6810.11 is for standard masonry units. Another common misclassification is HS code 9406.90 for prefabricated buildings. While structural components are used to make buildings, 9406 is only for complete or substantially complete buildings presented as a single unit. Individual beams or slabs always fall under 6810.91.
