HS Code for High carbon steel billets

High carbon steel billets are classified under HS code 7207.20 because they represent semi-finished products of iron or non-alloy steel containing, by weight, 0.25% or more of carbon. According to the General Rules of Interpretation (GRI) and the Chapter 72 notes, semi-finished products are continuous cast products or forged items that have not yet been rolled or worked into finished shapes like bars, rods, or sheets. The classification specifically targets the carbon content threshold; once the carbon content reaches or exceeds 0.25%, the product moves from the low-carbon subheadings into 7207.20. These billets serve as the primary feedstock for the production of high-strength wires, springs, and structural components. The metallurgical composition must be strictly non-alloy, meaning no other elements (like chromium or manganese) exceed the specific weight percentages defined in Note 1(f) to Chapter 72.

Products Included

• Continuous cast high carbon steel billets
• Forged steel blooms with carbon content exceeding 0.25%
• Rectangular or square semi-finished steel slabs
• High carbon steel rounds for seamless tube production
• Semi-finished billets intended for high-tensile wire drawing

Common Misclassification

A frequent error involves confusing high carbon steel billets (7207.20) with low carbon steel billets, which fall under 7207.11 (rectangular cross-section) or 7207.12 (other cross-sections) if the carbon content is below 0.25%. Additionally, if the steel contains alloying elements above the thresholds defined in the Harmonized System (e.g., more than 0.3% aluminum or 1.65% manganese), it must be classified under 7224.90 as alloy steel. Importers also occasionally mistake billets for finished bars (7214), but billets are distinguished by their rough surface and lack of specific finishing work.

FAQ

What is the HS code for high carbon steel billets?

The primary HS code for semi-finished products of non-alloy steel with 0.25% or more carbon is 7207.20.

How is a billet distinguished from a bloom in this HS code?

While both fall under 7207.20, a billet typically has a smaller square cross-section (usually less than 155mm x 155mm), whereas a bloom is larger and more rectangular, though the HS code treats them similarly based on carbon content.
