Harmonized System Code Classification

The first two digits of the HS code indicate that products starting with 73 typically represent steel products.

Specifically, Chapter 73 covers the following main contents:

• Steel products: Including various shapes of steel (such as plates, tubes, profiles, wires, etc.), as well as forged, cast, and stamped steel products.
• Fasteners such as screws, nuts, and washers
• Railway tracks and their accessories
• Other steel products, such as steel ropes, steel mesh, and steel structural components.

Why Chapter 73?

The HS code system classifies goods based on their material, use, and manufacturing method. Chapter 73 is specifically used to classify products primarily made of steel. Therefore, if a product is mainly composed of steel and falls within the category of steel products, it is typically classified under Chapter 73.

To determine a more specific HS code, the specific shape, size, use, and manufacturing process of the product must also be considered.
