Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If roasted for nickel recovery
Pyrrhotite-pyrite roaster products become nickel ores under Chapter 26.
If chemically processed iron oxides extracted
Oxidized forms from processing shift to Chapter 28 iron oxides.
If vermiculite or perlite contaminants dominate
Mixed with Chapter 2530 minerals, priority classification applies per notes.

Import Tips & Compliance
• Composition analysis required showing iron pyrite as chief characteristic constituent
• Monitor for magnetic pyrrhotite content which may affect end-use declaration accuracy
• Declare total sulfur content for proper duty assessment and environmental compliance
