HS Code for Prefabricated concrete beams

Prefabricated concrete beams are classified under HS code 6810.91 because they are structural components made of cement, concrete, or artificial stone. Chapter 68 covers articles of stone, plaster, and cement, and heading 6810 specifically addresses articles of cement or concrete, whether or not reinforced. The subheading 6810.91 is dedicated to prefabricated structural components for building or civil engineering. These beams are typically manufactured in a factory environment (precast) and then transported to construction sites for use in bridges, parking garages, or building frames. The classification is based on the material composition and the fact that they are finished structural elements rather than raw materials. Even if the beams contain steel reinforcement (rebar) or are prestressed, the concrete component determines the primary classification under this heading.

Products Included

• Concrete lintels for windows and doors
• Structural concrete girders
• Precast floor slabs (structural)

Common Misclassification

These beams are often misclassified under 9406.90 (prefabricated buildings). However, 9406 is for entire buildings or kits, whereas 6810.91 is for individual structural components. Another common error is using 6810.11, which is for building blocks and bricks. While both are concrete, 6810.91 is specifically for engineering components like beams and pillars. Additionally, some importers try to classify them under 7308 if they are heavily reinforced with steel, but since the concrete provides the volume and form, 6810 remains the correct heading.

FAQ

What is the HS code for prefabricated concrete beams?
