Import Tips

• Provide manufacturer's assay certificate specifying exact silicon percentage and impurity levels

• Ship in inert atmosphere packaging to prevent oxidation, which could affect purity claims

• Watch for reclassification if ingots exceed 100mm diameter and appear 'worked' per HTS terms
