Import Tips
• Provide chemical analysis certificates specifying silicon and tungsten percentages; U.S. notes require verification of alloy compositions
• Use moisture-proof bags to prevent silicon degradation during ocean transit; declare as 'ferrosilicon tungsten' explicitly
• Avoid classification errors with ferrosilicon (7202.21); tungsten content distinguishes this under 7202.80
