Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If silica content exceeds 50% forming natural silica sand mix
Quartz-pyrite sands classify primarily as silica sands under heading 2505.
If pebbles or gravels with minor pyrite content
Pyrite gravel mixtures fall under Chapter note priority for heading 2517.
If calcined for refractory brick production
Heat-treated pyrites become refractory materials excluding Chapter 25 raw state.

Import Tips & Compliance
• Screening certificates showing natural grain size distribution prevent classification as manufactured powders
• Test for acid-generating potential; may require special waste handling declarations
• Bulk shipments need moisture content verification to avoid liquefaction hazards at sea
