HS Code for Ferrocerium

Ferrocerium is classified under HS code 3606.90 because it is defined as a pyrophoric alloy. While the material contains iron and rare-earth metals such as cerium, its primary functional characteristic is the ability to emit sparks when subjected to friction. According to the General Rules of Interpretation (GRI) and the Explanatory Notes to Chapter 36, pyrophoric alloys in all forms are specifically assigned to this heading. This classification takes precedence over Chapter 72 (Iron and Steel) because the pyrophoric property is the defining feature for trade, safety, and regulatory purposes. The material is typically traded in the form of small rods, flints, or blocks used in mechanical ignition devices rather than as a bulk alloying agent for steelmaking.

Products Included

• Lighter flints for cigarette lighters
• Ferrocerium rods for survival fire starters
• Mischmetal alloys in pyrophoric forms
• Sparking metal alloys for gas lighters
• Pyrophoric pellets for industrial ignition

Common Misclassification

Ferrocerium is frequently misclassified under HS code 7202.99, which covers other ferro-alloys. While ferrocerium is technically an alloy of iron and cerium, the Harmonized System dictates that products with pyrophoric properties must be classified in Chapter 36. Another common error is using HS code 3606.10, which is reserved for liquid or liquefied-gas fuels in containers for filling lighters, whereas ferrocerium is a solid alloy.

FAQ

What is the HS code for Ferrocerium?

The HS code for ferrocerium in all forms, including lighter flints and fire-starting rods, is 3606.90.

Is ferrocerium classified as a hazardous material for shipping?

Yes, because it is classified under Chapter 36 as a pyrophoric alloy, it is often subject to Class 4.1 (Flammable Solids) regulations during transport.
