Harmonized System Code Classification

The first two digits of the HS code "73" represent steel products.

Specifically, Chapter 73 covers the following main contents:

• Steel products: Including various shapes of steel products, such as angle steel, channel steel, flat steel, round steel, steel pipes, steel plates, steel wire, steel nails, bolts, nuts, etc.
• Cast iron products: Including various cast iron products, such as pipes, pipe fittings, valves, cookware, radiators, etc.
• Other steel products: Including steel mesh, steel ropes, steel springs, steel chains, etc.

Reason for classification:

The classification principle of HS codes is based on the material, use, and manufacturing method of the goods. Steel products in Chapter 73 are classified according to the main material being steel.

In summary, if the main component of the product is steel, and it is various shapes of steel products, cast iron products, or other steel products, it is likely to be classified into Chapter 73.

Hope this explanation is helpful to you!

First four digits explanation: HS code: 7305

Classification description: Other tubes and profiles (e.g., welded, riveted, or similarly closed), with a circular cross-section, iron or steel tubes and profiles with an external diameter exceeding 406.4 millimeters.

Specific meaning: Refers to iron or steel tubes and profiles with a circular cross-section and an external diameter greater than 406.4 millimeters, which are closed by welding, riveting, or similar methods.

Six-digit explanation: Classification: Other tubes and profiles (e.g., welded, riveted, or similarly closed), with a circular cross-section, iron or steel tubes and profiles with an external diameter exceeding 406.4 millimeters.

Specific meaning:

• 7305.31: Refers to other iron or steel tubes and profiles with an external diameter exceeding 406.4 millimeters, welded, longitudinally welded, other, alloy steel, other.

8-10 digit explanation: hscode: 7305314000 Classification: Other tubes and profiles (e.g., welded, riveted, or similarly closed), with a circular cross-section, iron or steel tubes and profiles with an external diameter exceeding 406.4 millimeters: --> other, welded: --> longitudinally welded: --> other: --> iron or non-alloy steel Explanation: This HS code belongs to iron or steel tubes and profiles with a circular cross-section, an external diameter exceeding 406.4 millimeters, specifically other welded tubes, longitudinally welded, and made of iron or non-alloy steel.

Example products: * Large-diameter steel pipes used in oil and gas transportation * Steel structural profiles for construction * Welded steel tubes for industrial equipment * Longitudinally welded steel pipes for water supply and drainage systems * Non-alloy steel pipes for mechanical engineering applications
