HS Code for High carbon steel slabs

High carbon steel slabs 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 defined as continuous cast products or forged products that have not yet been rolled into finished shapes like plates, sheets, or bars. The classification specifically targets the carbon content threshold; steel with less than 0.25% carbon falls under different subheadings. These slabs are typically rectangular in cross-section, with a width considerably greater than the thickness, and serve as the primary feedstock for hot-rolling mills. The metallurgical properties of high carbon steel, such as increased hardness and tensile strength, necessitate this specific classification to distinguish it from mild or low-carbon variants used in general construction.

Products Included

• High carbon steel rectangular slabs
• Semi-finished blooms with carbon content ≥ 0.25%
• High carbon steel billets for wire rod production
• Forged semi-finished blocks of non-alloy high carbon steel
• Continuous cast slabs intended for further rolling

Common Misclassification

A frequent error involves misclassifying these products under HS code 7207.11 or 7207.12, which are reserved for steel containing less than 0.25% carbon. Importers must verify the mill test certificate to confirm the carbon weight percentage. Additionally, if the steel contains alloying elements (such as chromium, nickel, or molybdenum) above the thresholds defined in Note 1(f) to Chapter 72, it must be classified under heading 7224 as alloy steel, regardless of the carbon content. Another common mistake is using heading 7208, which is strictly for flat-rolled products that have already undergone the rolling process and are considered finished goods.

FAQ

What is the HS code for high carbon steel slabs?

The primary HS code for semi-finished high carbon steel slabs containing 0.25% or more carbon by weight is 7207.20.

How do I distinguish between a slab and a plate for customs?

A slab (7207) is a semi-finished product with rough surfaces and unworked edges, whereas a plate (7208) is a finished flat-rolled product with precise dimensions and a smoother surface finish.
