HS Code for Silicomanganese

Silicomanganese is classified under HS code 720230, which specifically covers ferro-silico-manganese. This classification is determined by the product's status as a ferro-alloy, as defined in Note 1(c) to Chapter 72. To be classified here, the alloy must contain by weight more than 4% iron and more than 8% manganese, along with a significant proportion of silicon. Silicomanganese is a critical intermediary product used in the iron and steel industry, primarily as a deoxidizer and an alloying element to improve the mechanical properties of the final steel product. The Harmonized System places it in Chapter 72 because it is a primary form of ferrous metal that is not useful for rolling or forging in its current state but is essential for the production of other ferrous metals. The specific subheading 720230 is reserved for alloys where both manganese and silicon provide the primary functional characteristics, distinguishing it from pure ferromanganese or ferrosilicon.

Common Misclassification

Silicomanganese is frequently confused with ferromanganese, which is classified under HS code 720211 (containing more than 2% carbon) or 720219 (other). The distinction lies in the silicon content; if the silicon content is negligible, it remains under 720211. Another common error is classifying it as ferrosilicon under HS code 720221, which is reserved for alloys where silicon is the primary alloying element without the requisite manganese levels. Importers must verify the chemical assay to ensure the manganese and silicon percentages meet the thresholds defined for 720230.

FAQ

What is the HS code for Silicomanganese?

The HS code for silicomanganese is 720230, which falls under the category of ferro-alloys.

Is silicomanganese classified as a chemical or a metal?

In the Harmonized System, silicomanganese is classified as a ferro-alloy within Chapter 72 (Iron and Steel), rather than as a chemical compound in Chapter 28, because it is a metallic alloy used in metallurgy.
