Product classification
HS code for Silicomanganese: 7202.30
Ferro-alloys, ferro-silico-manganese.
Classification of silicomanganese under HS 7202.30
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.

Codes often confused with 7202.30
Common mistake. 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.
Top exporters and importers of HS 720230 (the code used for silicomanganese), 2025
In 2025, the largest exporter of HS 720230 (the code used for silicomanganese) in UN Comtrade data was India, with 36% of world exports; the largest importer in UN Comtrade data was the United States, with 12% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 720230, not only silicomanganese.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about silicomanganese
What is the HS code for Silicomanganese?
The HS code for Silicomanganese is 720230 (Ferro-alloys; ferro-silico-manganese). The HS code for silicomanganese is 720230, which falls under the category of ferro-alloys.
How do I classify Silicomanganese for customs?
Silicomanganese is classified under HS code 720230 — Ferro-alloys; ferro-silico-manganese. This is a 6-digit subheading level code.
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.
Which countries are the top exporters of silicomanganese (HS 720230)?
In 2025, the top exporters of HS 720230 (the code used for silicomanganese) in UN Comtrade data were India ($1.1B, 36% of world exports), Norway ($366M) and Malaysia ($342M). World exports came to about $3.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of silicomanganese (HS 720230)?
In 2025, the top importers of HS 720230 (the code used for silicomanganese) in UN Comtrade data were the United States ($388M, 12% of world imports), Japan ($218M) and Türkiye ($207M). World imports came to about $3.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
