3606.90.30.00 - Ferrocerium and other pyrophoric alloys

This HTS classification covers ferrocerium and other pyrophoric alloys. Pyrophoric materials are those that readily ignite when exposed to air. Ferrocerium is a man-made alloy, typically composed of iron and cerium with other rare-earth elements, known for its ability to produce sparks when struck or scraped, making it ideal for fire-starting devices like lighters and survival tools. This category also encompasses other alloys exhibiting similar pyrophoric properties, regardless of their specific composition or intended application.

Within this heading, this specific code, 3606.90.30.00, is distinct from its siblings by its focus on the alloy material itself. For instance, 3606.90.40.00 classifies metaldehyde, a chemical compound used as a pesticide, which lacks the inherent pyrophoric characteristics of the alloys covered here. Similarly, 3606.90.80.00 is a residual "other" category for combustible materials not otherwise specified within Chapter 36, implying that ferrocerium and other pyrophoric alloys have their own dedicated classification due to their unique properties and common applications.

As this is a leaf node within the HTS, there are no further subcategories to introduce. The classification of ferrocerium and other pyrophoric alloys under 3606.90.30.00 is definitive for these specific materials. When classifying goods, focus on the material composition and the inherent pyrophoric nature of the alloy. This ensures accurate differentiation from other combustible materials or distinct chemical compounds that might share some functional similarities but not the core material properties.
