HS Code for Hot-drawn alloy steel rods

Hot-drawn alloy steel rods are classified under HS code 7228.30 based on their metallurgical properties and the specific thermal-mechanical process used during manufacture. To fall under this code, the product must meet the definition of alloy steel, which requires the presence of one or more elements such as aluminum, boron, chromium, cobalt, copper, lead, manganese, molybdenum, nickel, niobium, silicon, titanium, tungsten, vanadium, or zirconium in specific weight percentages. The physical form must be a bar or rod, which are solid products that do not conform to the definitions of flat-rolled products or wire. The manufacturing process must be hot-rolling, hot-drawing, or extrusion. Hot-drawing involves pulling the steel through a die at high temperatures to achieve a specific cross-sectional shape and size. This code is specifically for products that have not been further worked than hot-processing, distinguishing them from cold-finished bars which have much tighter dimensional tolerances and different surface characteristics. These rods are essential in the production of fasteners, gears, and structural components in the aerospace and automotive industries.

Products Included

• Hot-drawn alloy steel round bars
• Hot-rolled alloy steel hexagonal rods
• Extruded alloy steel structural rods
• Alloy steel square bars (hot-processed)

Common Misclassification

A common error is classifying these under HS code 7228.50, which is reserved for bars and rods that are cold-formed or cold-finished. Cold-finished products undergo processing at room temperature to improve surface finish and strength. Another misclassification occurs with HS code 7214, which is only for non-alloy steel rods. Finally, if the rods are in irregularly wound coils, they should be classified under heading 7227 rather than 7228.

FAQ

What is the HS code for hot-drawn alloy steel rods?

The HS code for hot-rolled, hot-drawn, or extruded alloy steel bars and rods is 7228.30.

How do I distinguish between HS 7228.30 and 7228.50?

HS 7228.30 is for products that are hot-processed, whereas 7228.50 is for products that have been cold-formed or cold-finished after the initial rolling.
