HS Code for Ferroniobium

Ferroniobium is classified under HS code 7202.93 based on the General Rules for the Interpretation (GRI) of the Harmonized System, specifically GRI 1 and GRI 6. According to the legal notes of Chapter 72, specifically Note 1(c), ferro-alloys are defined as alloys in pigs, blocks, lumps, or similar primary forms, of a kind commonly used as an additive in the manufacture of other steels or as deoxidants, desulfurants, or for similar uses in ferrous metallurgy. Ferroniobium is a critical ferro-alloy composed of iron and niobium, typically containing between 60% and 70% niobium by weight. It is produced primarily through the aluminothermic reduction of niobium-bearing ores like pyrochlore. The classification under 7202.93 is mandatory because the Harmonized System provides a specific subheading for ferro-niobium. This alloy is primarily used in the production of High-Strength Low-Alloy (HSLA) steels, which are essential for modern infrastructure, including oil and gas pipelines, automotive frames, and structural beams. The presence of niobium helps refine the grain structure of the steel, significantly increasing its strength-to-weight ratio and toughness at low temperatures. To qualify for this code, the material must be in a primary form and must not be usefully malleable, distinguishing it from finished steel products or pure niobium metal.

Products Included

Common Misclassification

A frequent point of confusion involves HS code 8112.92, which covers unwrought niobium and niobium powders. The distinction lies in the iron content and the intended use. HS code 7202.93 is strictly for ferro-alloys, which must contain at least 4% iron by weight and are used as additives. If the material is high-purity niobium used for superconducting magnets, it falls under Chapter 81. Another potential error is using 7202.99, the residual category for other ferro-alloys, which is incorrect since 7202.93 is specific.

FAQ

What is the HS code for Ferroniobium?

The specific HS code for Ferroniobium is 7202.93, which falls under the heading for ferro-alloys.

Is Ferroniobium considered a hazardous material for shipping?

In its common lump form, it is generally classified as non-hazardous for transport, though dust or fine powders may require specific safety handling according to the Safety Data Sheet (SDS).
