HS Code for Bridge sections

Bridge sections and complete bridges made of iron or steel are classified under heading 7308. This heading covers structures and parts of structures of iron or steel, excluding prefabricated buildings of heading 9406. Specifically, HS code 7308.10 is dedicated to "Bridges and bridge-sections." This classification is appropriate when the steel components have been further worked (e.g., drilled, bent, or notched) or are presented as assembled or unassembled structures specifically designed for use in a bridge. The classification is based on the material (iron or steel) and the specific structural application. Even if the sections are shipped in pieces for ease of transport, they remain under 7308.10 as long as they are identifiable as bridge components. This follows GRI 2(a), which allows for the classification of incomplete or unassembled articles as the finished product if they have the essential character of that product. The engineering and fabrication level of these items distinguishes them from simple plates or beams found in earlier headings of Chapter 72 or 73.

Products Included

• Steel bridge girders and trusses
• Prefabricated bridge segments
• Iron bridge supports and pillars
• Modular steel bridge kits
• Decking sections for permanent bridges

Common Misclassification

Bridge sections are sometimes misclassified under 7301, which covers sheet piling, or 7304-7306 if they are simple tubes or pipes. Another common error is using 8428 if the section is part of a mechanical moving bridge (like a drawbridge), though the structural steel itself usually remains in 7308.10.

FAQ

What is the HS code for bridge sections?

The HS code for bridges and bridge-sections of iron or steel is 7308.10.

Are bolts and nuts included in this code?

While 7308.10 covers the structural sections, separate fasteners like bolts are usually classified under 7318, unless they are part of a complete unassembled bridge kit.
