Import Tips

• Provide mill test certificates verifying silicon content exceeds 90% by weight to avoid reclassification during customs examination

• Declare particle size and packaging details (e.g

• 1MT jumbo bags) as they impact handling but not tariff classification

• Watch for contamination risks during transit; no duty allowance for rust or discoloration per Chapter 72 notes
