Import Tips & Compliance
• Ensure the concentrate meets the definition of 'ores' under Chapter 26 Note 2 — it must not have undergone processes beyond those normal to the metallurgical industry
• Provide assay certificates showing silver content, as the statistical unit of measure is based on metal content
• Verify whether the gold content triggers additional reporting under other tariff items
