HS Code for Silico-manganese steel bars

Silico-manganese steel bars are classified under HS code 7228.20. This classification is governed by the notes to Chapter 72, which define "other alloy steel" and specifically "silico-manganese steel." According to Chapter 72, Note 1(f), silico-manganese steel must contain by weight: not more than 0.7% of carbon, 0.5% or more but not more than 1.9% of manganese, and 0.6% or more but not more than 2.3% of silicon. Heading 7228 covers "Other bars and rods of other alloy steel; angles, shapes and sections, of other alloy steel; hollow drill bars and rods, of alloy or non-alloy steel." Subheading 7228.20 is the specific provision for bars and rods of silico-manganese steel that are not in irregularly wound coils. These products are typically used in the manufacture of springs or high-strength structural components. The classification is determined by the chemical composition of the alloy and the physical form of the product (straight lengths rather than coils).

Products Included

• Hot-rolled silico-manganese steel bars
• Cold-finished or cold-drawn silico-manganese bars
• Forged silico-manganese steel bars
• Rectangular, circular, or polygonal cross-section bars
• Spring steel bars of silico-manganese alloy

Common Misclassification

The most common misclassification is with HS code 7227.20. While both codes cover silico-manganese steel, 7227.20 is strictly for bars and rods in irregularly wound coils. If the bars are in straight lengths, they must be classified under 7228.20. Another error involves 7214, which is for non-alloy steel bars; if the silicon and manganese levels meet the thresholds defined in the Chapter Notes, the product must be classified as alloy steel under 7228.

FAQ

What is the HS code for silico-manganese steel bars?

The HS code for silico-manganese steel bars in straight lengths is 7228.20.

What defines a bar as silico-manganese steel?

It must meet specific chemical thresholds: carbon ≤ 0.7%, manganese 0.5%–1.9%, and silicon 0.6%–2.3% by weight.
