Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as ferrosilicon rather than ferrophosphorus
Ferrosilicon has distinct silicon content; misidentified high-P alloys go under different ferroalloy subheading.
If derived from phosphate slag waste rather than intentional alloy production
Slag and ash containing ferrous phosphides classify under Chapter 26 mineral wastes.

Import Tips & Compliance
• Submit chemical analysis reports from accredited labs showing Fe-P composition to support HTS 7202 classification
• Avoid common pitfall of classifying as scrap metal; ferrophosphorus is a purpose-made alloy, not waste
• Declare exact phosphorus percentage on entry as it affects steel industry end-use compliance
